Inside the AT&T TSD-3600E Telephone Security Device, an encrypting telephone from 1993 based on the controversial Clipper Chip
The Clipper chip was the flagship component of a controversial National Security Agency-designed "key escrow" cryptography scheme, in which intercepted encrypted traffic could be decrypted easily by law enforcement or intelligence agencies for surveillance purposes. The program was extremely controversial and, in the end, not a success. Aside from the obvious fundamental problems (the security risks of having a large database of citizen's keys, the need to implement cryptography in expensive secret hardware, etc), the Clipper architecture had technical flaws that made it possible to circumvent the escrow features and preclude the possibility of law enforcement access. (See "Protocol Failure in the Escrowed Encryption Standard" [pdf format], for details.)
AT&T (my employer at the time) was the first (and ultimately only) company to build a commercial product based on the ill-fated system. The AT&T TSD-3600, announced in 1992, was a voice encryption device designed to be installed in a standard telephone (between the phone base and the handset). Calls placed to other TSD-3600-equipped telephones could be automatically digitized (at 4800bps) and encrypted, making eavesdropping on the conversation (by legal or illegal means) effectively infeasible. When the US government learned of AT&T's plans to market the device, it worried that criminals might used them to thwart wiretaps. Plans for a new encryption system with a wiretap backdoor were hurriedly drawn up by the NSA, and AT&T was persuaded to replace the regular (non-escrowed) DES-based encryption scheme in the original TSD product with the new system, called the Clipper chip. The Clipper-based model TSD-3600E hit the market in 1993. As incentive for AT&T's cooperation, the government agreed to purchase a significant quantity of Clipper-equipped TSD-3600Es, which sold for over $1000 each in quantity.
Hobbled by the controversial key escrow features and the high retail price, the government ended up being the TSD's only major customer, and even most of the units they bought sat unopened in storage for over ten years. AT&T, for its part, eventually sold off the division that produced the product.
I'm aware of five different TSD-3600 models produced between 1992 and the product's cancellation, differing in the cipher algorithm used. The TSD-3600D was the original, using standard DES with a 56 bit key. (These were quickly recalled and disappeared from the market after Clipper was announced). The 3600F was an exportable model that used a proprietary 40 bit cipher that, I was told, was "embarassingly" weak even given the short key. The 3600P used a proprietary 56 bit cipher similar to DES (but not inter-operable with the 3600D). The 3600E was the first controversial key escrowed model, with the then-classified Skipjack cipher and key escrow features implemented on a tamper-resistant MYK-78T Clipper chip. A later model, the 3600S, included a Clipper chip but would also downgrade (or upgrade, depending on your opinion of key escrow) to the F or P ciphers when communicating with those models. All five models use a Diffie-Hellman key exchange (768 bit, if I recall correctly) to establish a session key, a 4 character hash of which is displayed on each unit's LCD. To detect "man-in-the-middle" attacks, users could verify (by voice) that their displayed hashes matched.
This photo shows an open unit with its main circuit board exposed. The MYK-78T Clipper chip is visible in the far right of the board. The gray handset module at the front is a removable part that matches the unit to the audio and electrical levels of particular telephones.

As the 21st century dawned, an emerging generation of artists expanded the performance of self-fashioning, in which dress functions as a signifier of disidentification with the dominant social orders; their aim was to formulate modes of expression that affirm communal identity. In an age when issues of race, ethnicity, religion, gender, and sovereignty dominate national and geopolitical discourse, textiles, "as dense and multivalent sites of encryption," may, art historian Julia Bryan-Wilson argues, "alert others to our sense of self and signal our attempt to collectively belong."
In 2003 Liz Collins created "Pride Dress", in collaboration with designer Gary Graham, as part of a series of representations of the seven deadly sins. Today, the tattered gown with its torn and distressed flags precariously tacked together transcends its initial signification to reverberate with the roiling gender wars that rend the fabric of American society.

"Ants are more like the parts of an animal than entities on their own. They are mobile cells, circulating through a dense connective tissue of other ants in a matrix of twigs. The circuits are so intimately interwoven that the anthill meets all the essential criteria of an organism.

One of the world’s most confounding literary mysteries may finally be, in part, solved: the author of the mysterious and as-yet untranslatable Voynich manuscript has been identified as a Jewish physician based in northern Italy, an expert in medieval manuscripts has claimed.
The Voynich manuscript is an illustrated book printed on vellum written entirely in an indecipherable script, leaving scholars and code-breakers scratching their heads since it re-emerged a century ago.
Writing in the foreword of a new facsimile of the 15th-century codex, Stephen Skinner claims visual clues in each section provide evidence of the manuscript’s author. If proved true, Skinner believes his theory will help unlock more secrets of the coded manuscript.
The Voynich manuscript: the unbreakable encryption?

The scholar draws evidence for his theory of the author’s identity from a range of illustrations in the manuscript, particularly a section in which naked women are depicted bathing in green pools supplied by intestinal-like pipes.
The doctor, whose work includes editing the spiritual diaries of the Tudor mystic John Dee, believes the illustrations show communal Jewish baths called mikvah, which are still used in Orthodox Judaism to clean women after childbirth or menstruation.
Pointing to the fact that the pictures show only nude women and no men, Skinner told the Guardian: “The only place you see women like that bathing together in Europe at that time was in the purification baths that have been used by Orthodox Jews for the last 2,000 years.”
He believes the drawings were of an invention designed by the mysterious author that aimed to ensure an efficient supply of clean water to a mikvah. “I think there is no other explanation for what they are: it is either rank fantasy by the author – which doesn’t really fit with the medical, herbal and cosmological sections of the manuscript – or it is a mikvah,” he said.
Other evidence Skinner uses to support his theory include the lack of Christian symbolism in the manuscript – unusual at a time of deep religious superstition, as the Inquisition enforced orthodox religion and punished any hint of heresy. “There are no saints or crosses, not even in the cosmological sections,” he said.
onsidered in addition to the absence of religious symbolism, Skinner said, visual clues in the manuscript suggest its author was a Jewish physician and herbalist. Many of the plants depicted, alongside astrological charts, are medicinal herbs, such as opium and cannabis. “In those days, doctors had to be astrologers as well, so they could determine the nature of an illness and treatment.”

Although Jews were persecuted in the Inquisition, they were in demand as doctors due to their knowledge of Mediterranean botany, he added.

A visual clue to the geographical origin of the manuscript in northern Italy lies in a sketch of a castle with a “swallow-tail” on one page. The unusual design, Skinner believes, is a Ghibelline fortification found only in castles in northern Italy in the 15th century. Many of the region’s towns, such as Pisa, had significant Jewish populations and could have inspired the Germanic style of some of the illustrations because the ruling family was allied to the German Holy Roman Emperor, instead of the pope.
He admitted his theory will have to be rigorously tested by other scholars, but added that he felt “85% certain” he was right. Skinner, who is an expert in medieval esoteric manuscripts, said he was now searching European Jewish books from the period for similar language, codes, scripts or linguistic patterns to those in the Voynich.
Should he succeed, Skinner will have solved a problem that has frustrated academics, cryptographers and computer programming experts since it was discovered in 1912 by the Polish collector Wilfrid Voynich.
Although there were allegations that Voynich had faked the book, the vellum and ink has been carbon dated to between 1404 and 1438. The authorship of the manuscript has led to heated debate with characters as varied as Dee and Leonardo da Vinci being posited as responsible for the manuscript.
Dee has also been suggested as a possible owner of the Voynich manuscript, a claim refuted by Skinner because the Tudor doctor and mystic was a notorious vandal of manuscripts that came into his hands. “The ladder-like symbol of his ownership is not on there and he hasn’t written anything on it,” he said, adding: “A temptation is always to find a name that everyone recognises, but I think it is unlikely to be by anyone famous.”
Skinner is hopeful that facsimiles of the manuscript will help decode it. “If it is in bookshops, someone might pick it up and recognise something in it that they are working with in another field of scholarship,” he said.
Asked what secrets he hopes it will reveal, he cited the medieval use of willow bark which provided the basis of aspirin: “It would be lovely if the herbalist section provided cures for things that we have forgotten about.”

A lot of my friends are using LR and raves about it. But somehow I am not convinced.
Due to the RAW encryption that Nikon (also Canon) put on its RAW file, Abobe softwares would never be able to get the 100% accuracy of what Nikon (Canon) wants the picture to look like. And I will stick with accuracy over convenient any times.

Quantum computing represents a groundbreaking advancement in technology, deeply intertwined with the concepts of superposition, entanglement, and interference from quantum physics. Unlike classical computing, which processes information in a linear fashion using bits (0s and 1s), quantum computing utilizes quantum bits or qubits that can exist in multiple states simultaneously. This enables quantum computers to perform numerous calculations at once, effectively navigating through a vast landscape of potential solutions.
The idea of parallel timelines can be likened to the way quantum computers operate. Each decision or computation can be viewed as branching into multiple outcomes, similar to how different timelines might unfold based on various choices. This means that a quantum computer can explore various paths to a solution simultaneously, leading to remarkable efficiencies in solving complex problems.
In practical terms, this capability could revolutionize fields such as cryptography, where quantum computers may break existing encryption methods faster than classical computers. In material science, they could simulate quantum phenomena to discover new materials with desirable properties. Additionally, in optimization problems across various industries, quantum computing offers the potential to find the most efficient solutions more rapidly than traditional methods.
In summary, the link between quantum computing and the concept of parallel timelines highlights a fascinating intersection of technology and theoretical physics, suggesting that our understanding of reality may be more complex and interconnected than we previously imagined.

Star Trek, First Contact (Paramount, 1996).

Star Trek - 'Beyond First Contact' The Borg - Making The Movie.
Starring Patrick Stewart, Jonathan Frakes, Brent Spiner, LeVar Burton, Michael Dorn, Gates McFadden, Marina Sirtis, Alfre Woodard, James Cromwell, Alice Krige, Neal McDonough, Robert Picardo, and Dwight Schultz. Directed by Jonathan Frakes.
Captain Jean-Luc Picard awakens from a nightmare about his Borg assimilation experience to an incoming message from Admiral Hayes. Hayes informs Picard that Deep Space Five reported that a colony has been destroyed. Completing the Admiral's sentence, Picard realizes who destroyed the colony — the Borg.
Picard calls a meeting and informs his senior officers that their ship has been instructed to patrol the Neutral Zone. Their orders are to protect the area from any possible Romulan uprising during a Borg attack. Despite protests from his officers, Picard remains faithful to his orders and the U.S.S. Enterprise NCC 1701-E begins to patrol the area. Later, Picard regretfully tells Riker that it is his own fault they are stuck in the Neutral Zone. Starfleet believes Picard to be too emotionally involved with the Borg because of his previous assimilation to tactically complete a mission against them.
The men return to the bridge to learn that Starfleet has engaged in combat with the Borg. Intercepting messages between the starships, the crew learns that the Federation is losing. Picard, with his Borg experience, knows he can help the fleet. He informs his staff that he will make a decision directly in opposition to Starfleet commands. With no objections from his crew, Captain Picard gives the order and the starship Enterprise sets a course for Earth and the attacking Borg cube.
A massive battle ensues and it appears that the Federation will lose the fight. Despite serious structural damage to the Borg cube, their strength does not weaken. Even the U.S.S. Defiant, commanded by Worf, does not appear to be able to turn the tides of the battle. As the starship Defiant is about to ram the Borg ship on a suicide run, the U.S.S. Enterprise beams aboard its crew, including Worf. Picard, having an inside perspective of the Borg and their vessel, focuses the firepower of the fleet on coordinates he knows to be critical. Just as the main ship is destroyed, a spherical escape pod flies out. The sphere creates a temporal vortex, catching the starship Enterprise in its wake. Immune to the paradoxes created by the time travel, the starship's crew learns that Earth at the present time appears to be inhabited entirely by the Borg. The commanding officers realize that the Borg have gone into the past and assimilated Earth, so they follow them back in time to repair the damage the Borg have done.
On Earth, over three centuries earlier, a somber Lily Sloane accompanies a stumbling, drunk Zefram Cochrane out of a bar after a night of revelry. Then, Lily notices a fast moving light. She hardly has time to ask what the object is, when the Borg vessel attacks. Back aboard the Enterprise, Picard demands that Data tell him the exact date and location the Borg ship is attacking. The location: central Montana. The date: April 4, 2063 — the day before First Contact. Realizing that the Borg have come to prevent first contact between alien life forms and humans, the crew knows they must stop the Borg and facilitate this exchange. They destroy the Borg sphere, and Dr. Crusher, Captain Picard, Commander Data, Commander Riker, Counselor Troi and other U.S.S. Enterprise crew transport down to Earth to survey the damage.
At the Borg attack site in Montana, the crew finds destruction and chaos. They split into groups to search for Cochrane. Data and Picard hunt for Cochrane's warp ship, the Phoenix. There they encounter a very angry and confused Lily, who believes Data and Picard to be members of a coalition that broke the cease-fire after World War III. She shoots at them in a rage, but impervious to bullets, Data approaches Lily. Overcome by fear and radiation, she falls to the ground. Dr. Crusher diagnoses Lily with radiation sickness caused by the damaged Phoenix, and inoculates the entire crew. Against Picard's better judgment, Crusher takes Lily to sickbay. Geordi is called to help repair the warp vessel and Picard becomes intrigued by its historical significance. In this vessel began the future as the world would know it, and the past as Picard remembers it. He reaches out to touch the ship. Data, curious about the human need for tactile reinforcement, attempts to create the same feelings he observes in Picard, but is unsuccessful in duplicating this aspect of humanity.
Aboard the ship, two crewmembers are sent to examine unexplained maintenance problems, and both disappear. Picard is called to the ship and discovers that the survivors from the Borg sphere have transported onto the ship and are taking over Deck 16. While Picard arranges teams to fight them, the Borg manipulate the climate of the deck to suit their needs and begin to spread throughout the ship. When the Borg attack sickbay, Crusher, her staff, and Lily escape through a Jeffries tube, thanks to a distraction by the ship's Emergency Medical Hologram. While Crusher leads the group down the passageway, Lily steals away in a different direction.
On Earth, Riker finds Troi and Cochrane drunk in a bar. Troi justifies that the only way she could get Cochrane to talk to her was by shooting Tequila with him. Denying her drunken state, Troi offers her professional opinion on Cochrane. She explains, "He's nuts."
Picard and his team are tracking the Borg through the starship. As Crusher and her staff find Worf's team, Picard's team encounters the Borg, who have begun to assimilate U.S.S. Enterprise crewmembers. Worf's team engages the Borg in combat, but the enemies adapt to the crew's weapons too quickly to make any difference. The teams are ordered to regroup on Deck 15, but Data is captured. Picard cannot save him, so he quickly crawls into a Jeffries tube to escape. Face to face with Picard, Lily steals his phaser and demands an explanation and escape route. Picard agrees.
Geordi shows Cochrane the starship Enterprise through a large telescope on Earth and tries to convince him to launch his vessel the next morning. Geordi glorifies Cochrane by explaining that his ship will make first contact with alien life forms. Humanity will be saved if Cochrane launches his ship. Still drunk, Cochrane agrees.
Aboard the ship, the Borg Queen introduces herself to a bound Data, claiming that she is the Collective. Reactivating Data's emotion chip, the Borg begin to graph organic, human skin onto the android's arm. As Data is overcome by this new human sensation of touch, something he never thought possible, the Borg continue their work.
Lily and Picard wander through the service deck as the captain attempts to explain what has happened between Lily's time and his own. She begins to calm down until they suddenly run into a Borg-infested area. Quickly escaping in the Holodeck, Picard activates a Dixon Hill program. At a dance, he and Lily try to blend in without being noticed by the Borg. Following the Holodeck's story, Picard searches for Nicky the Nose and takes his machine gun. Killing the Borg with the gun, Picard retrieves the memory chip that contains all of the information the Borg has received. Lily then notices that the two dead Borg were once crewmembers of the U.S.S. Enterprise.
Back on Earth, Cochrane keeps hearing what an amazing historical figure he is and begins to question whether or not he wants to go through with the launch. He doubts his own nobility and flees the launch site. Geordi and Riker attempt to catch up with Cochrane in the woods and are forced to stun him with a phaser to return him to the Phoenix.
Lily and Picard join the rest of the surviving crew and discover that the Borg are outside of the ship. The retrieved memory chip reveals that they are reconfiguring the main deflector in order to contact the Borg of this century, calling them to Earth to assimilate the planet. Picard, Worf and Lieutenant Hawk put on space suits and venture onto the surface of the starship to stop the Borg.
Aware of Data's desire to become human, the Borg Queen offers him the chance to be entirely covered in human flesh and join the Borg, in an attempt to get the encryption codes from Data so she can obtain total control over the U.S.S. Enterprise. Outside the Enterprise, Hawk, Worf and Picard attempt to unlock the deflector dish. Attacked by a Borg, Worf's suit begins to depressurize. Two Borg are killed and Hawk is attacked. As the dish is released, a now-assimilated Hawk attempts to kill Picard. Worf saves the captain, but Hawk is killed. Picard and Worf then destroy the free-floating deflector dish.
On Earth, Cochrane explains to Riker that his only motivation for inventing warp travel was money. He never expected to save mankind, become a hero, or be instrumental in the founding of a new civilization. He simply wanted to retire in peace.
An argument ensues aboard the Enterprise as the majority of the senior officers believe that they should evacuate the ship, destroying it and the Borg. Picard won't give up, and insists they stay. Challenged by Worf, Picard orders him off the Bridge. Lily follows Picard into his ready room and demands that he explain his obsession with fighting the Borg. Picard declares he won't sacrifice the starship, and swears to finally make the Borg pay for all they've done. Lily quietly and calmly compares Picard to Captain Ahab, forever fighting his white whale — the Borg. Realizing that this fight could only destroy himself and his crew, Picard decides to evacuate the ship. Worf, Picard and Crusher activate the ship's self-destruct sequence. The countdown begins, and the crew leaves in escape pods. Picard surveys his ship and prepares to leave when he hears Data calling him.
Meanwhile , the earth-bound crew and Cochrane begin takeoff. Cochrane, Geordi and Riker take off in the Phoenix, and with music blaring, the three men launch successfully into orbit.
On the ship, Lily and Picard say good-bye and the captain goes to save Data. Entering Engineering, Picard confronts the Borg Queen, whom he knows from his experience with the Borg. The queen reminds Picard that it was not enough that he was assimilated, but that he needed to give himself freely to the Borg — she wished him to stand by her side as an equal to further the power of the Collective. Picard offers himself in exchange for Data, but the android does not comply. He refuses to leave, and at the queen's command, disarms the self-destruct sequence. He quickly enters the encryption codes, offering full control of the Enterprise to the Borg.
As Cochrane's ship nears warp, Data arms the U.S.S Enterprise's weapons and aims them at the defenseless Phoenix. At the Borg Queen's order, Data fires, but the missiles fail to hit the Phoenix. His deception of the Borg complete, Data smashes a conduit, releasing a gas that floods engineering, killing all organic material. As the Borg are destroyed, Picard climbs to safety and the Borg Queen falls into the deadly gas. With the Borg threat gone, Cochrane safely completes humanity's first warp flight.
Celebrating the flight back on Earth that night, Cochrane and the Enterprise crew see an alien ship land nearby. The doors open, and Zefram Cochrane makes Earth's first contact with an alien race — the Vulcans. Picard and his crew beam out, having witnessed this historic event, and the U.S.S Enterprise NCC 1701-E returns to the 24th century.

At the Borg attack site in Montana, the crew finds destruction and chaos. They split into groups to search for Cochrane. Data and Picard hunt for Cochrane's warp ship, the Phoenix. There they encounter a very angry and confused Lily, who believes Data and Picard to be members of a coalition that broke the cease-fire after World War III. She shoots at them in a rage, but impervious to bullets, Data approaches Lily. Overcome by fear and radiation, she falls to the ground. Dr. Crusher diagnoses Lily with radiation sickness caused by the damaged Phoenix, and inoculates the entire crew. Against Picard's better judgment, Crusher takes Lily to sickbay. Geordi is called to help repair the warp vessel and Picard becomes intrigued by its historical significance. In this vessel began the future as the world would know it, and the past as Picard remembers it. He reaches out to touch the ship. Data, curious about the human need for tactile reinforcement, attempts to create the same feelings he observes in Picard, but is unsuccessful in duplicating this aspect of humanity.
Aboard the ship, two crewmembers are sent to examine unexplained maintenance problems, and both disappear. Picard is called to the ship and discovers that the survivors from the Borg sphere have transported onto the ship and are taking over Deck 16. While Picard arranges teams to fight them, the Borg manipulate the climate of the deck to suit their needs and begin to spread throughout the ship. When the Borg attack sickbay, Crusher, her staff, and Lily escape through a Jeffries tube, thanks to a distraction by the ship's Emergency Medical Hologram. While Crusher leads the group down the passageway, Lily steals away in a different direction.
On Earth, Riker finds Troi and Cochrane drunk in a bar. Troi justifies that the only way she could get Cochrane to talk to her was by shooting Tequila with him. Denying her drunken state, Troi offers her professional opinion on Cochrane. She explains, "He's nuts."
Picard and his team are tracking the Borg through the starship. As Crusher and her staff find Worf's team, Picard's team encounters the Borg, who have begun to assimilate U.S.S. Enterprise crewmembers. Worf's team engages the Borg in combat, but the enemies adapt to the crew's weapons too quickly to make any difference. The teams are ordered to regroup on Deck 15, but Data is captured. Picard cannot save him, so he quickly crawls into a Jeffries tube to escape. Face to face with Picard, Lily steals his phaser and demands an explanation and escape route. Picard agrees.
Geordi shows Cochrane the starship Enterprise through a large telescope on Earth and tries to convince him to launch his vessel the next morning. Geordi glorifies Cochrane by explaining that his ship will make first contact with alien life forms. Humanity will be saved if Cochrane launches his ship. Still drunk, Cochrane agrees.
Aboard the ship, the Borg Queen introduces herself to a bound Data, claiming that she is the Collective. Reactivating Data's emotion chip, the Borg begin to graph organic, human skin onto the android's arm. As Data is overcome by this new human sensation of touch, something he never thought possible, the Borg continue their work.
Lily and Picard wander through the service deck as the captain attempts to explain what has happened between Lily's time and his own. She begins to calm down until they suddenly run into a Borg-infested area. Quickly escaping in the Holodeck, Picard activates a Dixon Hill program. At a dance, he and Lily try to blend in without being noticed by the Borg. Following the Holodeck's story, Picard searches for Nicky the Nose and takes his machine gun. Killing the Borg with the gun, Picard retrieves the memory chip that contains all of the information the Borg has received. Lily then notices that the two dead Borg were once crewmembers of the U.S.S. Enterprise.
Back on Earth, Cochrane keeps hearing what an amazing historical figure he is and begins to question whether or not he wants to go through with the launch. He doubts his own nobility and flees the launch site. Geordi and Riker attempt to catch up with Cochrane in the woods and are forced to stun him with a phaser to return him to the Phoenix.
Lily and Picard join the rest of the surviving crew and discover that the Borg are outside of the ship. The retrieved memory chip reveals that they are reconfiguring the main deflector in order to contact the Borg of this century, calling them to Earth to assimilate the planet. Picard, Worf and Lieutenant Hawk put on space suits and venture onto the surface of the starship to stop the Borg.
Aware of Data's desire to become human, the Borg Queen offers him the chance to be entirely covered in human flesh and join the Borg, in an attempt to get the encryption codes from Data so she can obtain total control over the U.S.S. Enterprise. Outside the Enterprise, Hawk, Worf and Picard attempt to unlock the deflector dish. Attacked by a Borg, Worf's suit begins to depressurize. Two Borg are killed and Hawk is attacked. As the dish is released, a now-assimilated Hawk attempts to kill Picard. Worf saves the captain, but Hawk is killed. Picard and Worf then destroy the free-floating deflector dish.
On Earth, Cochrane explains to Riker that his only motivation for inventing warp travel was money. He never expected to save mankind, become a hero, or be instrumental in the founding of a new civilization. He simply wanted to retire in peace.
An argument ensues aboard the Enterprise as the majority of the senior officers believe that they should evacuate the ship, destroying it and the Borg. Picard won't give up, and insists they stay. Challenged by Worf, Picard orders him off the Bridge. Lily follows Picard into his ready room and demands that he explain his obsession with fighting the Borg. Picard declares he won't sacrifice the starship, and swears to finally make the Borg pay for all they've done. Lily quietly and calmly compares Picard to Captain Ahab, forever fighting his white whale — the Borg. Realizing that this fight could only destroy himself and his crew, Picard decides to evacuate the ship. Worf, Picard and Crusher activate the ship's self-destruct sequence. The countdown begins, and the crew leaves in escape pods. Picard surveys his ship and prepares to leave when he hears Data calling him.
Meanwhile , the earth-bound crew and Cochrane begin takeoff. Cochrane, Geordi and Riker take off in the Phoenix, and with music blaring, the three men launch successfully into orbit.
On the ship, Lily and Picard say good-bye and the captain goes to save Data. Entering Engineering, Picard confronts the Borg Queen, whom he knows from his experience with the Borg. The queen reminds Picard that it was not enough that he was assimilated, but that he needed to give himself freely to the Borg — she wished him to stand by her side as an equal to further the power of the Collective. Picard offers himself in exchange for Data, but the android does not comply. He refuses to leave, and at the queen's command, disarms the self-destruct sequence. He quickly enters the encryption codes, offering full control of the Enterprise to the Borg.
As Cochrane's ship nears warp, Data arms the U.S.S Enterprise's weapons and aims them at the defenseless Phoenix. At the Borg Queen's order, Data fires, but the missiles fail to hit the Phoenix. His deception of the Borg complete, Data smashes a conduit, releasing a gas that floods engineering, killing all organic material. As the Borg are destroyed, Picard climbs to safety and the Borg Queen falls into the deadly gas. With the Borg threat gone, Cochrane safely completes humanity's first warp flight.
Celebrating the flight back on Earth that night, Cochrane and the Enterprise crew see an alien ship land nearby. The doors open, and Zefram Cochrane makes Earth's first contact with an alien race — the Vulcans. Picard and his crew beam out, having witnessed this historic event, and the U.S.S Enterprise NCC 1701-E returns to the 24th century.
I attended a class in Dallas, Texas, that covers classification of encryption software for export control purposes. I might as well have gone to clown school! After listening to everything that's covered and the reporting process, I'm sure there must've been a meeting I missed where no one volunteered and my name came up as an ideal person to take this role. I'd bet when I submit the first request they come back with what kind of clown sent this!
If we read this sign the French way (that is, backwards), then this zone has free drugs. And lots of it.
This sign is almost as ridiculous as software licenses that say the licensees must obey local laws (or even have specific parts of local laws, such as export restrictions, written into it).
Of course licensees must obey local laws. A license cannot make an illegal act legal magically, no more than a street sign will make illegal drugs legal and legal drugs illegal. But a license must not include these particular restrictions placed by the law in itself---then, when the law is changed (such as U.S. export laws regarding encryption), the license itself will be the fetter that binds---a truly nonfree license.

Star Trek - 'Beyond First Contact' The Borg - Making The Movie.
Starring Patrick Stewart, Jonathan Frakes, Brent Spiner, LeVar Burton, Michael Dorn, Gates McFadden, Marina Sirtis, Alfre Woodard, James Cromwell, Alice Krige, Neal McDonough, Robert Picardo, and Dwight Schultz. Directed by Jonathan Frakes.
Captain Jean-Luc Picard awakens from a nightmare about his Borg assimilation experience to an incoming message from Admiral Hayes. Hayes informs Picard that Deep Space Five reported that a colony has been destroyed. Completing the Admiral's sentence, Picard realizes who destroyed the colony — the Borg.
Picard calls a meeting and informs his senior officers that their ship has been instructed to patrol the Neutral Zone. Their orders are to protect the area from any possible Romulan uprising during a Borg attack. Despite protests from his officers, Picard remains faithful to his orders and the U.S.S. Enterprise NCC 1701-E begins to patrol the area. Later, Picard regretfully tells Riker that it is his own fault they are stuck in the Neutral Zone. Starfleet believes Picard to be too emotionally involved with the Borg because of his previous assimilation to tactically complete a mission against them.
The men return to the bridge to learn that Starfleet has engaged in combat with the Borg. Intercepting messages between the starships, the crew learns that the Federation is losing. Picard, with his Borg experience, knows he can help the fleet. He informs his staff that he will make a decision directly in opposition to Starfleet commands. With no objections from his crew, Captain Picard gives the order and the starship Enterprise sets a course for Earth and the attacking Borg cube.
A massive battle ensues and it appears that the Federation will lose the fight. Despite serious structural damage to the Borg cube, their strength does not weaken. Even the U.S.S. Defiant, commanded by Worf, does not appear to be able to turn the tides of the battle. As the starship Defiant is about to ram the Borg ship on a suicide run, the U.S.S. Enterprise beams aboard its crew, including Worf. Picard, having an inside perspective of the Borg and their vessel, focuses the firepower of the fleet on coordinates he knows to be critical. Just as the main ship is destroyed, a spherical escape pod flies out. The sphere creates a temporal vortex, catching the starship Enterprise in its wake. Immune to the paradoxes created by the time travel, the starship's crew learns that Earth at the present time appears to be inhabited entirely by the Borg. The commanding officers realize that the Borg have gone into the past and assimilated Earth, so they follow them back in time to repair the damage the Borg have done.
On Earth, over three centuries earlier, a somber Lily Sloane accompanies a stumbling, drunk Zefram Cochrane out of a bar after a night of revelry. Then, Lily notices a fast moving light. She hardly has time to ask what the object is, when the Borg vessel attacks. Back aboard the Enterprise, Picard demands that Data tell him the exact date and location the Borg ship is attacking. The location: central Montana. The date: April 4, 2063 — the day before First Contact. Realizing that the Borg have come to prevent first contact between alien life forms and humans, the crew knows they must stop the Borg and facilitate this exchange. They destroy the Borg sphere, and Dr. Crusher, Captain Picard, Commander Data, Commander Riker, Counselor Troi and other U.S.S. Enterprise crew transport down to Earth to survey the damage.

Vera Wilde, artist-in-residence at Hack42. Because Art & Science!
Hackerspace Hack42 is proudly hosting a new artist-in-residence. Dr. Vera K. Wilde (PhD PoliSci) is a (former) Harvard Kennedy School researcher. She is working on re-branding the Dark-Web to the EDTR-web, a place for Expressing, Dissenting, Teaching and Resisting.
The EDTR-web is using technologies like TOR and encrypted communications tools to create a place of freedom where centralised power cannot reach.
Vera will be using arts (oil painting and songwriting) as well as writing and political science methods to define and develop the EDTR-web as a social space and technological phenomenon.
Vera's third photo-shoot, in which we get to play with some theatrical props and explore extreme opposites.
Special thanks go to Moem for mixing up a batch of red paint and for producing the mad-mad-mad bloody special FX on the baseball-bat.

" the brain had the ability to go beyond what could be achieved by axioms or formal systems. This would mean that the mind had some additional function that was not based on algorithms (systems or rules of calculation). A computer is driven solely by algorithms. Penrose asserted that the brain could perform functions that no computer could perform. He called this type of functioning "non-computable".
" information is Platonic, the three worlds ;
physical, mental, and the Platonic mathematical world. In his theory, the physical world can be seen as the external reality, the mental world as information processing in the brain and the Platonic world as the encryption, measurement, or geometry of fundamental spacetime that is claimed to support non-computational understanding.°

Inscription pasted in front of book "To William Bellows, Esq as a memento of the unveiling on 19 Oct 1925 of the tablet to Sir Charles Wheatstone, from his grandson Charles Wheatstone Salmi, Down End, Chilbolton, Hants". Sir Charles Wheatstone (6 February 1802 – 19 October 1875), was an English scientist and inventor of many scientific breakthroughs of the Victorian era, including the English concertina, the stereoscope (a device for displaying three-dimensional images), and the Playfair cipher (an encryption technique). However, Wheatstone is best known for his contributions in the development of the Wheatstone bridge, originally invented by Samuel Hunter Christie, which is used to measure an unknown electrical resistance, and as a major figure in the development of telegraphy.

Speaking with Chris Anderson and Tim Berners Lee on a telepresence robot, beaming in from a secret location in Russia.
The video is online, and more photos below
Some of his zingers:
I am living proof that an individual can go head to head against the most powerful agency in the world and win.
Democracy may die behind closed doors. We don’t have to give up privacy to have good government, we don’t have to give up liberty to have security.
Boundless Informant is a program the NSA hid from Congress. It tells us that more communications are being intercepted in America about Americans than there are in Russia about Russians. I’m not sure that’s what an intelligence agency should be aiming for.
Dick Cheney is really something else.
The public interest is not always the same as the national interest.
At the NSA, "terrorism" is used as a cover for action. Terrorism provokes an emotional response that allows people to rationalize and authorize programs they wouldn’t have otherwise. They asked for this authority in the 1990s and Congress said no.
I grew up in the Internet. Although I never expected to have the chance to defend it in such a direct and practical manner, or to embody it in this unusual, avatar manner, there’s something poetic about it.
(Facing Tim Berners Lee on stage): A Magna Carta for the Internet is exactly what we need to encode values not just in writing but in the structure of the Internet.
PRISM is about content. It deputizes corporate America to do the dirty work for the NSA. Even though some companies did resist, they lost. But this was never tried by open court, only by secret court... making secret interpretations of the law. There have been 34,000 warrant requests in 33 years and they only rejected 11 government requests.
(Of 1.7 million documents, only a hundred have been shared so far. Is there more to come?). There are absolutely more revelations to come. Some of the most important reporting is yet to come.
The biggest thing an Internet company in America can do today without consulting lawyers to protect users worldwide is to enable SSL web encryption on every page you visit.
(When asked if he would return to America If given amnesty): Absolutely. There’s really no question. The government has hinted they want some kind of deal, a compromise deal to come back. But I want to make it very clear. I did not do this to be safe. I did this to do what was right. I won’t stop working in the public interest just to benefit myself.
Beneath Bishop’s Bridge Road, halfway between Sheldon Square and the entrance to Paddington underground station, you’ll find an intriguing work of art. Curated by Futurecity on behalf of British Land, this permanent installation is a collaboration between United Visual Artists and poet Nick Drake.
Alan Turing is one of Paddington’s most famous sons. This artwork, Message From the Unseen World, celebrates his groundbreaking work on artificial intelligence. Its outer shell comprises aluminium panels, punctuated with holes. LED lights shine through the holes, forming the words to Drake’s poem. A Turing-inspired algorithm shuffles through the poem, creating new interpretations of the verse.
You can see the full poem below.
MESSAGE FROM THE UNSEEN WORLD
Nick Drake
This is Alan speaking
to you who pass by this bridge
in the enchantment of time
under the echoing arch
over the mirror of water
on your way to work or home
and to other places in the infinity
held in the secret dream cave
of your mysterious minds
This is Alan speaking
through this interface with time and space
I am the ghost in the universal machine
the one I dreamed as I lay on the grass
that grew in the green of lost time
of a meadow in Grantchester alone
thinking about whoever I was in love with at the time
and the unchanging truth of numbers
in their beautiful equations
and the enigma of human beings
in their infinite possible configurations -
I was puzzling the problem of the apple
of the knowledge of good and evil -
For on that day you eat of it
you shall surely die
but the winding snake
the only creature coded as a question
looked me in the eye and asked
in his intelligent high voice -
What’s wrong with this picture?
Why do starfish have five arms
and why are they fish not stars?
What connects stars and grains of sand?
What is the secret ciphered in a fir cone?
Why is the heart always on the left?
Natural wonders every child should know…
He smiled like the flickering pages of a book -
Christopher, my first true love, appeared
his beautiful fingers blue with ink
holding his telescope and the star globe
I made him as a present -
We lay side by side
looking through the window at the stars
naming the constellations
as they wheeled across the night
The maths brain lies often awake in his bed
Doing logs to ten places and trig in his head
When I woke in the shock of light
he was gone
and nothing was ever the same again
What happens to the dead
when spirit separates from matter?
Is time a river ever giving birth
in an endless wheel?
Why is loss always incalculable?
What is the heart’s square root,
its point and infinite recurrences?
This is Alan speaking
perhaps you wish to hear about the task
of deciphering the Enigma messages?
It was the impossible before breakfast
to imagine the unimaginable
the day after war was declared -
but a logical theorem says
you can deduce everything from a contradiction
so we imagined a cryptanalytic machine
an electric brain ticking away
to solve the insoluble
to sort the irrelevant from the essential
to discover the heart of the mystery
in thousands of meaningless signals every day
enciphered and sent by the enemy
in billions of different possible combinations -
like reading a poem written in random static
in wind and rain and dark
threaded with the dot and dash of Morse
encrypted transmitted transcribed
but there was one clue -
a letter was never enciphered as itself
so that was the starting point
to find the letters that made the only word
that helped to save ships and lives
in the middle of the Atlantic
and some say win the war -
We kept hush hush but I wondered
Could a machine be intelligent and if so how?
Could a machine be fascinated by another machine?
Could machines talk to each other?
Could a machine experience delight
and suffer fear and jealousy?
If a machine could dream what would it dream
in the forest of the night?
Could a machine fall sick or fall in love?
Could a machine imagine the future?
This is Alan speaking
we devised the Automatic Computing Engine
capable of calculating anything
quantified in an algorithm
and that was the basis of the future -
But how is it I found myself
a stranger in a room alone
a sequence of contradictory instructions
coded into my criminal heart?
Of gross indecency accused
I replied truthfully
Englishman atheist mathematician
Order of the British Empire
Recreations listed in Who’s Who
chess long-distance running gardening
(the last a kind of lie, I like wild flowers) -
Homosexual cryptographer
noble in reason or traitor in his bones?
Unable to say a word of what I knew
unable to speak the unspeakable
secret within the secret
I felt no guilt -
They offered me a choice
Prison or probation
with hormonal emasculation -
I made my decision
and emerged a different man
Why does nothing happen for a long time
Then everything suddenly changes?
Why does the rational give rise to the irrational?
Who is this man kissing me on the mouth?
Is he telling truth or lies?
This is Alan speaking
now as I could not speak before
to you who were unborn when I died -
Oh beautiful people of tomorrow
we are not fallen creatures
life is the only garden
the apple is love
two Adams, two Eves
in open celebration hand in hand
So I delight to watch you dance
in the enchantment of time
like angels in a forest of mirrors
but in the age of shopping
festivals and information consumption
the sign of the bitten apple is everywhere
and your lives are held in the beautiful devices
familiar in your hands -
So revel in your liberty
but read between the lines
you are becoming information
touch screen to touch screen
connected but alone
the algorithm of desires and dreams
end to end encryption held
in the infinite memory of the great ghost server
How did the zebra get its stripes
and the leopard its disguise of spots?
Why does a snail have a spiral shell?
Why do sunflowers follow not just the sun
but the Fibonacci sequence
in the structure of their beautiful faces?
How does a bud of cells generate your seeing eyes
and beating heart?
This is Alan speaking
I have been waiting a long time
puzzling everything and nothing -
I leave no note of explanation
but a mystery story
it is an ordinary summer evening
by the side of my bed is found
a half-eaten slice of apple
Dip the apple in the brew
let the sleeping death seep through -
I lie alone for the last time
at the edge of reality
my arms at my sides
like a badly-dressed figure on a tomb
looking out of the window at the sun
setting for the final night
a golden apple in the black branches
of a tree of shadows where the birds quibble -
until it disappears into the dark

Fangruida: human landing on Mars 10 cutting-edge technology
[Fangruida- human landing on Mars 10 innovative and sophisticated technologies]
Aerospace Science and space science and technology major innovation of the most critical of sophisticated technology R & D project
-------------------------------------------------- -------------
Aerospace Science Space Science and Technology on behalf of the world's most cutting-edge leader in high technology, materials, mechatronics, information and communication, energy, biomedical, marine, aviation aerospace, microelectronics, computer, automation, intelligent biochips, use of nuclear energy, light mechanical and electrical integration, astrophysics, celestial chemistry, astrophysics and so a series of geological science and technology. Especially after the moon landing, the further development of mankind to Mars and other planets into the powerful offensive, the world's major powers eager to Daxian hand of God, increase investment, vigorously develop new sophisticated technology projects for space to space. Satellite, space station, the new spacecraft, the new space suits, the new radiation protection materials, intelligent materials, new manufacturing technology, communications technology, computer technology, detector technology, rover, rover technology, biomedical technology, and so one after another, is expected to greater breakthroughs and leaps. For example, rocket technology, spacecraft design, large power spacecraft, spacesuits design improvements, radiation multifunctional composite materials, life health care technology and space medicine, prevention against microgravity microgravity applicable drugs, tracking control technology, landing and return technology. Mars lander and returned safely to Earth as a top priority. Secondly, Mars, the Moon base and the use of transforming Mars, the Moon and other development will follow. Whether the former or the latter, are the modern aerospace science, space science basic research, applied basic research and applied research in the major cutting-edge technology. These major cutting-edge technology research and innovation, not only for human landing on Mars and the safe return of great significance, but for the entire space science, impact immeasurable universe sciences, earth sciences and human life. Here the most critical of the most important research projects of several sophisticated technology research and development as well as its core technology brief. Limit non-scientific techniques include non-technical limits of technology, the key lies in technology research and development of technology maturity, advanced technology, innovative, practical, reliable, practical application, business value and investment costs, and not simply like the idea mature technology achievements, difficult to put into things. This is the high-tech research and development, testing, prototype, test application testing, until the outcome of industrialization. Especially in aerospace technology, advanced, novelty, practicality, reliability, economy, maturity, commercial value and so on. For technical and research purely science fiction and the like may be irrelevant depth, but not as aerospace engineering and technology practice. Otherwise, Mars will become a dream fantasy, and even into settling crashed out of danger.
Regardless of the moon or Mars, many technical difficulties, especially a human landing on Mars and return safely to Earth, technical difficulties mainly in the following aspects. (Transformation of Mars and the Moon and other planets and detect other livable technology more complex and difficult, at this stage it is difficult to achieve and therefore not discussed in detail in this study). In fact, Mars will be the safe return of a full set of technology, space science, aerospace crucial scientific research development, its significance is not confined to Mars simply a return to scientific value, great commercial value, can not be measure.
1. Powered rocket, the spacecraft overall structural design not be too complex large, otherwise, the safety factor to reduce the risk of failure accidents. Fusion rocket engine main problem to be solved is the high-temperature materials and fuel ignition chamber (reaction chamber temperatures of up to tens of millions of supreme billion degrees), fissile class rocket engine whose essence is the miniaturization of nuclear reactors, and placed on the rocket. Nuclear rocket engine fuel as an energy source, with liquid hydrogen, liquid helium, liquid ammonia working fluid. Nuclear rocket engine mounted in the thrust chamber of the reactor, cooling nozzle, the working fluid delivery and control systems and other components. This engine due to nuclear radiation protection, exhaust pollution, reactor control and efficient heat exchanger design and other issues unresolved. Electrothermal rocket engine utilizing heat energy (resistance heating or electric arc heating) working medium (hydrogen, amines, hydrazine ), vaporized; nozzle expansion accelerated after discharged from the spout to generate thrust. Static rocket engine working fluid (mercury, cesium, hydrogen, etc.) from the tank enter the ionization chamber is formed thrust ionized into a plasma jet. Electric rocket engines with a high specific impulse (700-2500 sec), extremely long life (can be repeated thousands of times a starter, a total of up to thousands of hours of work). But the thrust of less than 100N. This engine is only available for spacecraft attitude control, station-keeping and the like. One nuclear - power rocket design is as follows: Firstly, the reactor heats water to make it into steam, and then the high-speed steam ejected, push the rocket. Nuclear rocket using hydrogen as working substance may be a better solution, it is one of the most commonly used liquid hydrogen rocket fuel rocket carrying liquid hydrogen virtually no technical difficulties. Heating hydrogen nuclear reactor, as long as it eventually reaches or exceeds current jet velocity hydrogen rocket engine jet speed, the same weight of the rocket will be able to work longer, it can accelerate the Rockets faster. Here there are only two problems: First, the final weight includes the weight of the rocket in nuclear reactors, so it must be as light as possible. Ultra-small nuclear reactor has been able to achieve. Furthermore, if used in outer space, we can not consider the problem of radioactive residues, simply to just one proton hydrogen nuclei are less likely to produce induced radioactivity, thus shielding layer can be made thinner, injected hydrogen gas can flow directly through the reactor core, it is not easy to solve, and that is how to get back at high speed heated gas is ejected.
Rocket engine with a nuclear fission reactor, based on the heating liquid hydrogen propellant, rather than igniting flammable propellant
High-speed heavy rocket is a major cutting-edge technology. After all, space flight and aircraft carriers, submarines, nuclear reactors differ greatly from the one hand, the use of traditional fuels, on the one hand can be nuclear reactor technology. From the control, for security reasons, the use of nuclear power rocket technology, safe and reliable overriding indicators. Nuclear atomic energy in line with the norms and rules of outer space. For the immature fetal abdominal hatchery technology, and resolutely reject use. This is the most significant development of nuclear-powered rocket principle.
Nuclear-powered spaceship for Use of nuclear power are three kinds:
The first method: no water or air space such media can not be used propeller must use jet approach. Reactor nuclear fission or fusion to produce a lot of heat, we will propellant (such as liquid hydrogen) injection, the rapid expansion of the propellant will be heated and then discharged from the engine speed tail thrust. This method is most readily available.
The second method: nuclear reactor will have a lot of fast-moving ions, these energetic particles moving very fast, so you can use a magnetic field to control their ejection direction. This principle ion rocket similar to the tail of the rocket ejected from the high-speed mobile ions, so that the recoil movement of a rocket. The advantage of this approach is to promote the unusually large ratio, without carrying any medium, continued strong. Ion engine, which is commonly referred to as "electric rocket", the principle is not complicated, the propellant is ionized particles,
Plasma Engine
Electromagnetic acceleration, high-speed spray. From the development trend, the US research scope covers almost all types of electric thrusters, but mainly to the development of ion engines, NASA in which to play the most active intake technology and preparedness plans. "
The third method: the use of nuclear explosions. It is a bold and crazy way, no longer is the use of a controlled nuclear reaction, but to use nuclear explosions to drive the ship, this is not an engine, and it is called a nuclear pulse rocket. This spacecraft will carry a lot of low-yield atomic bombs out one behind, and then detonated, followed by a spacecraft propulsion installation disk, absorbing the blast pushing the spacecraft forward. This was in 1955 to Orion (Project Orion) name of the project, originally planned to bring two thousand atomic bombs, Orion later fetal nuclear thermal rocket. Its principle is mounted on a small rocket reactor, the reactor utilizing thermal energy generated by the propellant is heated to a high temperature, high pressure and high temperature of the propellant from the high-speed spray nozzle, a tremendous impetus.
Common nuclear fission technologies, including nuclear pulse rocket engines, nuclear rockets, nuclear thermal rocket and nuclear stamping rockets to nuclear thermal rocket, for example, the size of its land-based nuclear power plant reactor structure than the much smaller, more uranium-235 purity requirements high, reaching more than 90%, at the request of the high specific impulse engine core temperature will reach about 3000K, require excellent high temperature properties of materials.
Research and test new IT technologies and new products and new technology and new materials, new equipment, things are difficult, design is the most important part, especially in the overall design, technical solutions, technical route, technical process, technical and economic particularly significant. The overall design is defective, technology there are loopholes in the program, will be a major technical route deviation, but also directly related to the success of research trials. so, any time, under any circumstances, a good grasp of the overall control of design, technical design, is essential. otherwise, a done deal, it is difficult save. aerospace technology research and product development is true.
3, high-performance nuclear rocket
Nuclear rocket nuclear fission and fusion energy can rocket rocket two categories. Nuclear fission and fusion produce heat, radiation and shock waves and other large amounts of energy, but here they are contemplated for use as a thermal energy rocket.
Uranium and other heavy elements, under certain conditions, will split their nuclei, called nuclear fission reaction. The atomic bomb is the result of nuclear fission reactions. Nuclear fission reaction to release energy, is a million times more chemical rocket propellant combustion energy. Therefore, nuclear fission energy is a high-performance rocket rockets. Since it requires much less propellant than chemical rockets can, so to its own weight is much lighter than chemical rockets energy. For the same quality of the rocket, the rocket payload of nuclear fission energy is much greater than the chemical energy of the rocket. Just nuclear fission energy rocket is still in the works.
Use of nuclear fission energy as the energy of the rocket, called the atomic rockets. It is to make hydrogen or other inert gas working fluid through the reactor, the hydrogen after the heating temperature quickly rose to 2000 ℃, and then into the nozzle, high-speed spray to produce thrust.
A vision plan is to use liquid hydrogen working fluid, in operation, the liquid hydrogen tank in the liquid hydrogen pump is withdrawn through the catheter and the engine cooling jacket and liquid hydrogen into hydrogen gas, hydrogen gas turbine-driven, locally expansion. Then by nuclear fission reactors, nuclear fission reactions absorb heat released, a sharp rise in temperature, and finally into the nozzle, the rapid expansion of high-speed spray. Calculations show that the amount of atomic payload rockets, rocket high chemical energy than 5-8 times.
Hydrogen and other light elements, under certain conditions, their nuclei convergent synthesis of new heavy nuclei, and release a lot of energy, called nuclear fusion reaction, also called thermonuclear reaction.
Using energy generated by the fusion reaction for energy rocket, called fusion energy rocket or nuclear thermal rockets. But it is also not only take advantage of controlled nuclear fusion reaction to manufacture hydrogen bombs, rockets and controlled nuclear fusion reaction needs still studying it.
Of course there are various research and development of rocket technology and technical solutions to try.
It is envisaged that the rocket deuterium, an isotope of hydrogen with deuterium nuclear fusion reaction of helium nuclei, protons and neutrons, and release huge amounts of energy, just polymerized ionized helium to temperatures up to 100 million degrees the plasma, and then nozzle expansion, high-speed ejection, the exhaust speed of up to 15,000 km / sec, atomic energy is 1800 times the rocket, the rocket is the chemical energy of 3700 times.
Nuclear rocket engine fuel as an energy source, with liquid hydrogen, liquid helium, liquid ammonia working fluid. Nuclear rocket engine mounted in the thrust chamber of the reactor, cooling nozzle, the working fluid delivery and control systems and other components. In a nuclear reactor, nuclear energy into heat to heat the working fluid, the working fluid is heated after expansion nozzle to accelerate to the speed of 6500 ~ 11,000 m / sec from the discharge orifice to produce thrust. Nuclear rocket engine specific impulse (250 to 1000 seconds) long life, but the technology is complex, apply only to long-term spacecraft. This engine due to nuclear radiation protection, exhaust pollution, reactor control and efficient heat exchanger design and other issues not resolved, is still in the midst of trials. Nuclear rocket technology is cutting-edge aerospace science technology, centralized many professional and technical sciences and aerospace, nuclear physics, nuclear chemistry, materials science, the long term future ___-- wide width. The United States, Russia and Europe, China, India, Japan, Britain, Brazil and other countries in this regard have studies, in particular the United States and Russia led the way, impressive. Of course, at this stage of nuclear rocket technology, technology development there are still many difficulties. Fully formed, still to be. But humanity marching to the universe, nuclear reactor applications is essential.

The traditional lead-acid battery PbO2 monomer is a positive electrode plate and a negative electrode plate spongy Pb composition, not a super cell. : Silicon solar cells, multi-compound thin film solar cells, multi-layer polymer-modified electrode solar cells, nano-crystalline solar cells, batteries and super class. For example, the solar aircraft .10. To protect the health and life safety and security systems. Lysophosphatidic acid LPA is a growth factor-like lipid mediators, the researchers found that this substance can on apoptosis after radiation injury and animal cells was inhibited. Stable lysophosphatidic acid analogs having the hematopoietic system and gastrointestinal tract caused by acute radiation sickness protection, knockout experiments show that lysophosphatidic acid receptors is an important foundation for the protection of radiation injury. In addition to work under high pressure, the astronauts face a number of health threats, including motion sickness, bacterial infections, blindness space, as well as psychological problems, including toxic dust. In the weightless environment of space, the astronaut's body will be like in preadolescents, as the emergence of various changes.
Plantar molt
After the environment to adapt to zero gravity, the astronaut's body will be some strange changes. Weightlessness cause fluid flow around the main flow torso and head, causing the astronauts facial swelling and inflammation, such as nasal congestion. During long-term stay in space
Bone and muscle loss
Most people weightlessness caused by the impact may be known bone and muscle degeneration. In addition, the calcium bones become very fragile and prone to fracture, which is why some of the astronauts after landing need on a stretcher.
Space Blindness
Space Blindness refers astronaut decreased vision.
Solar storms and radiation is one of the biggest challenges facing the long-term space flight. Since losing the protection of Earth's magnetic field, astronauts suffer far more than normal levels of radiation. The cumulative amount of radiation exposure in low earth orbit them exceeded by workers close to nuclear reactors, thereby increasing the risk of cancer.
Prolonged space flight can cause a series of psychological problems, including depression or mood swings, vulnerability, anxiety and fear, as well as other sequelae. We are familiar with the biology of the Earth, the Earth biochemistry, biophysics, after all, the Earth is very different astrophysics, celestial chemistry, biophysics and astrophysics, biochemistry and other celestial bodies. Therefore, you must be familiar with and adapt to these differences and changes.
Osteoporosis and its complications ranked first in the space of disease risk.
Long-term health risks associated with flying Topics
The degree of influence long-term biological effects of radiation in human flight can withstand the radiation and the maximum limit of accumulated radiation on physiology, pathology and genetics.
Physiological effects of weightlessness including: long-term bone loss and a return flight after the maximum extent and severity of the continued deterioration of other pathological problems induced by the; maximum flexibility and severity of possible long-term Flight Center in vascular function.
Long-term risk of disease due to the high risk of flight stress, microbial variation, decreased immune function, leading to infections
Radiation hazards and protection
1) radiation medicine, biology and pathway effects Features
Radiation protection for interplanetary flight, since the lack of protective effect of Earth's magnetic field, and by the irradiation time is longer, the possibility of increased radiation hazard.
Analysis of space flight medical problems that may occur, loss of appetite topped the list, sleep disorders, fatigue and insomnia, in addition, space sickness, musculoskeletal system problems, eye problems, infections problems, skin problems and cardiovascular problems
---------------------------------------------------------
Development of diagnostic techniques in orbit, the development of the volume of power consumption, features a wide range of diagnostic techniques, such as applied research of ultrasound diagnostic techniques in the abdominal thoracic trauma, bone, ligament damage, dental / sinus infections and other complications and integrated;
Actively explore in orbit disposal of medical technology, weightlessness surgical methods, development of special surgical instruments, the role of narcotic drugs and the like.
——————————————————————————————-
However, space technology itself is integrated with the use of the most advanced technology, its challenging technical reserves and periodic demanding
With the continuous development of science and technology, space agencies plan a manned landing on the moon and Mars, space exploration emergency medicine current concern.
Space sickness
In the weightless environment of space, in the weightless environment of space, surgery may be extremely difficult and risky.
Robot surgeons
Space disease in three days after entering the space started to ease, although individual astronauts might subsequently relapse. January 2015 NASA declared working on a fast, anti-nausea and nasal sprays. In addition, due to the zero-gravity environment, and anti-nausea drugs can only be administered by injection or transdermal patches manner.
Manned spaceflight in the 21st century is the era of interplanetary flight, aerospace medicine is closely watched era is the era of China's manned space flourish. Only the central issue, and grasp the opportunity to open up a new world of human survival and development.
Various emergency contingency measures in special circumstances. Invisible accident risk prevention. Enhancing drugs and other screening methods immunity aerospace medicine and tissue engineering a microgravity environment. Drug mixture of APS, ginseng polysaccharides, Ganoderma lucidum polysaccharides, polysaccharides and Lentinan, from other compounds. Drug development space syndrome drug, chemical structure modification will be an important part.
These issues are very sensitive, cutting-edge technology is a major difficulty landing on Mars. Countries in the world, especially the world's major space powers in the country strategies and technical research, the results of all kinds continue to emerge. United States, Russia, China, Europe, India, Japan and other countries is different. United States, Russia extraordinary strength. Many patented technology and health, and most belong to the top-secret technology. Especially in aerospace engineering and technological achievements is different from the general scientific literature, practical, commercial, industrial great, especially the performance of patents, know-how, technical drawings, engineering design and other aspects. Present Mars and return safely to Earth, the first manned, significance, everything is hard in the beginning, especially the first person to land on Mars This Mars for Human Sciences Research Mars, the moon, the earth, the solar system and the universe, life and other significant. Its far greater than the value of direct investments and business interests.
In addition, it is the development of new materials, suitable for deep space operations universe, life, and other detection, wider field.
Many aerospace materials, continuous research and development of materials are key areas of aerospace development, including material rocket, the spacecraft materials, the suit materials, radiation materials, materials and equipment, instruments, materials and so on biochemistry.
Temperature metal-based compound with a metal matrix composite body with a more primordial higher temperature strength, creep resistance, impact resistance, thermal fatigue and other excellent high temperature performance.
In B, C, SiC fiber reinforced Ti3Al, TiAl, Ni3Al intermetallic matrix composites, etc.
W Fiber Reinforced with nickel-based, iron-based alloys as well as SiC, TiB2, Si3N4 and BN particle reinforced metal matrix composites
High temperature service conditions require the development of ceramic and carbon-based composite materials, etc., not in this eleven Cheung said.
Fuel storage
In order to survive in space, people need many things: food, oxygen, shelter, and, perhaps most importantly, fuel. The initial quality Mars mission somewhere around 80 percent of the space launch humans will be propellant. The fuel amount of storage space is very difficult.
This difference in low Earth orbit cause liquid hydrogen and liquid oxygen - rocket fuel - vaporization.
Hydrogen is particularly likely to leak out, resulting in a loss of about 4% per month.
When you want to get people to Mars speed to minimize exposure to weightlessness and space radiation hazards
Mars
Landings on the Martian surface, they realized that they reached the limit. The rapid expansion of the thin Martian atmosphere can not be very large parachute, such as those that will need to be large enough to slow down, carry human spacecraft.
Therefore, the parachute strong mass ratio, high temperature resistance, Bing shot performance and other aspects of textile materials used have special requirements, in order to make a parachute can be used in rockets, missiles, Yu arrows spacecraft and other spacecraft recovery, it is necessary to improve the canopy heat resistance, a high melting point polymeric fiber fabric used, the metal fabric, ceramic fiber fabrics, and other devices.
Super rigid parachute to help slow the landing vehicle.
Spacecraft entered the Martian atmosphere at 24,000 km / h. Even after slowing parachute or inflatable, it will be very
Once we have the protection of the Earth magnetic field, the solar radiation will accumulate in the body, a huge explosion threw the spacecraft may potentially lethal doses of radiation astronauts.
In addition to radiation, the biggest challenge is manned trip to Mars microgravity, as previously described.
The moon is sterile. Mars is another case entirely.
With dust treatment measures.
Arid Martian environment to create a super-tiny dust particles flying around the Earth for billions of years.
Apollo moon dust encountered. Ultra-sharp and abrasive lunar dust was named something that can clog the basic functions of mechanical damage. High chloride salt, which can cause thyroid problems in people.
Mars geological structure and geological structure of the moon, water on Mars geology, geology of the Moon is very important, because he, like the Earth's geology is related to many important issues. Water, the first element of life, air, temperature, and complex geological formations are geological structure. Cosmic geology research methods, mainly through a variety of detection equipment equipped with a space probe, celestial observations of atmospheric composition, composition and distribution of temperature, pressure, wind speed, vertical structure, composition of the solar wind, the water, the surface topography and Zoning, topsoil the composition and characteristics of the component surface of the rock, type and distribution, stratigraphic sequence, structural system and the internal shell structure.
Mars internal situation only rely on its surface condition of large amounts of data and related information inferred. It is generally believed that the core radius of 1700 km of high-density material composition; outsourcing a layer of lava, it is denser than the Earth's mantle some; outermost layer is a thin crust. Compared to other terrestrial planets, the lower the density of Mars, which indicates that the Martian core of iron (magnesium and iron sulfide) with may contain more sulfur. Like Mercury and the Moon, Mars and lack active plate movement; there is no indication that the crust of Mars occurred can cause translational events like the Earth like so many of folded mountains. Since there is no lateral movement in the earth's crust under the giant hot zone relative to the ground in a stationary state. Slight stress coupled with the ground, resulting in Tharis bumps and huge volcano. For the geological structure of Mars is very important, which is why repeated explorations and studies of Martian geological reasons.

Crust
The outermost layer of the crust.
Crustal thickness obtained, the original thickness of the low north 40 km south plateau 70 kilometers thick, an average of 50 kilometers, at least 80 km Tharsis plateau and the Antarctic Plateau, and in the impact basin is thin, as only about 10 kilometers Greece plains.
Canyon of Mars there are two categories: outflow channels (outflow channel) and tree valley (valley network). The former is very large, it can be 100 km wide, over 2000 km long, streamlined, mainly in the younger Northern Hemisphere, such as the plain around Tyre Chris Canyon and Canyon jam.
In addition, the volcanic activity sometimes lava formation lava channels (lava channel); crustal stress generated by fissures, faults, forming numerous parallel extending grooves (fossa), such as around the huge Tharsis volcanic plateau radially distributed numerous grooves, which can again lead to volcanic activity.
Presumably, Mars has an iron as the main component of the nucleus, and contains sulfur, magnesium and other light elements, the nuclear share of Mars, the Earth should be relatively small. The outer core is covered with a thick layer of magnesium-rich silicate mantle, the surface of rocky crust. The density of Earth-like planets Mars is the lowest, only 3.93g / cc.

Lunar core
The average density of the Moon is 3.3464 g / cc, the solar system satellites second highest (after Aiou). However, there are few clues mean lunar core is small, only about 350 km radius or less [2]. The core of the moon is only about 20% the size of the moon, the moon's interior has a solid, iron-rich core diameter of about 240 kilometers (150 miles); in addition there is a liquid core, mainly composed of iron outer core, about 330 km in diameter (205 miles), and for the first time compared with the core of the Earth, considered as the earth's outer core, like sulfur and oxygen may have lighter elements [4].
Chemical elements on the lunar surface constituted in accordance with its abundance as follows: oxygen (O), silicon (Si), iron (Fe), magnesium (Mg), calcium (Ca), aluminum (Al), manganese (Mn), titanium ( Ti). The most abundant is oxygen, silicon and iron. The oxygen content is estimated to be 42% (by weight). Carbon (C) and nitrogen (N) only traces seem to exist only in trace amounts deposited in the solar wind brings.

Moon geological history is an important event in recent global magma ocean crystallization. The specific depth is not clear, but some studies have shown that at least a depth of about 500 kilometers or more.
Lunar landscape
Lunar landscape can be described as impact craters and ejecta, some volcanoes, hills, lava-filled depressions.
Regolith
TABLE bear the asteroid and comets billions of years of bombardment. Over time, the impact of these processes have already broken into fine-grained surface rock debris, called regolith. Young mare area, regolith thickness of about 2 meters, while the oldest dated land, regolith thickness of up to 20 meters. Through the analysis of lunar soil components, in particular the isotopic composition changes can determine the period of solar activity. Solar wind gases possible future lunar base is useful because oxygen, hydrogen (water), carbon and nitrogen is not only essential to life, but also may be useful for fuel production. Lunar soil constituents may also be as a future source of energy.
Here, repeatedly stressed that the geological structure and geological structure of celestial bodies, the Earth, Moon, Mars, or that this human existence and development of biological life forms is very important, especially in a series of data Martian geological structure geological structure is directly related to human landing Mars and the successful transformation of Mars or not. for example, water, liquid water, water, oxygen, synthesis, must not be taken lightly.

Mars landing 10 Technology
Aerospace Science and space science and technology major innovation of the most critical of sophisticated technology R & D project
[
"1" rocket propulsion technology ion fusion nuclear pulse propulsion rocket powered high-speed heavy rocket technology, space nuclear reactors spacecraft] brought big problems reflected in the nuclear reaction, nuclear radiation on spacecraft launch, control, brakes and other impact.
In particular, for the future of nuclear power spacecraft, the need to solve the nuclear reactor design, manufacture, control, cooling, radiation shielding, exhaust pollution, high thermoelectric conversion efficiency and a series of technical problems.
In particular, nuclear reactors produce radiation on astronauts' health will pose a great threat, which requires the spacecraft to be nuclear radiation shielding to ensure astronaut and ship the goods from radiation and heat from the reactor influence, but this will greatly increase the weight of the detector.
Space nuclear process applications, nuclear reaction decay is not a problem, but in a vacuum, ultra-low temperature environment, the nuclear reaction materials, energy transport materials have very high demands.
Space facing the reality of a nuclear reactor cooling cooling problems. To prevent problems with the reactor, "Washington" aircraft carrier to take four heavy protective measures for the radiation enclosed in the warship. These four measures are: the fuel itself, fuel storage pressure vessel, reactor shell and the hull. US Navy fuel all metal fuel, designed to take the impact resistance of the war, does not release fission product can withstand more than 50 times the gravity of the impact load; product of nuclear fission reactor fuel will never enter loop cooling water. The third layer of protection is specially designed and manufactured the reactor shell. The fourth layer is a very strong anti-impact combat ship, the reactor is arranged in the center of the ship, very safe. Engage in a reactor can only be loaded up to the aircraft, so as to drive the motor, and then drive the propeller. That is the core advantage of the heat generated by the heated gas flow, high temperature high pressure gas discharge backward, thereby generating thrust.
.
After installation AMPS1000 type nuclear power plant, a nuclear fuel assembly: He is a core member of the nuclear fuel chain reaction. Usually made into uranium dioxide, of which only a few percent uranium-235, and most of it is not directly involved in the nuclear fission of uranium 238. The uranium dioxide sintered into cylindrical pieces, into a stainless steel or a zirconium alloy do metal tubes called fuel rods or the original, then the number of fuel rods loaded metal cylinder in an orderly composition of the fuel assembly, and finally put a lot of vertical distribution of fuel assemblies in the reactor.
Nuclear reactor pressure vessel is a housing for containing nuclear fuel and reactor internals, for producing high-quality high-strength steel is made to withstand the pressure of dozens MPa. Import and export of the coolant in the pressure vessel.
The top of the pressure vessel closure, and can be used to accommodate the fixed control rod drive mechanism, pressure vessel head has a semi-circular, flat-topped.
Roof bolt: used to connect the locking pressure vessel head, so that the cylinder to form a completely sealed container.
Neutron Source: Plug in nuclear reactors can provide sufficient neutron, nuclear fuel ignition, to start to enhance the role of nuclear reactors and nuclear power. Neutron source generally composed of radium, polonium, beryllium, antimony production. Neutron source and neutron fission reactors are fast neutron, can not cause fission of uranium 235, in order to slow down, we need to moderator ---- full of pure water in a nuclear reactor. Aircraft carriers, submarines use nuclear reactor control has proven more successful.
Rod: has a strong ability to absorb neutrons, driven by the control rod drive mechanism, can move up and down in a nuclear reactor control rods within the nuclear fuel used to start, shut down the nuclear reactor, and maintain, regulate reactor power. Hafnium control rods in general, silver, indium, cadmium and other metals production.
Control rod drive mechanism: He is the executive body of nuclear reactors operating system and security protection systems, in strict accordance with requirements of the system or its operator control rod drives do move up and down in a nuclear reactor, nuclear reactor for power control. In a crisis situation, you also can quickly control rods fully inserted into the reactor in order to achieve the purpose of the emergency shutdown
Upper and lower support plate: used to secure the fuel assembly. High temperature and pressure inside the reactor is filled with pure water (so called pressurized water reactors), on the one hand he was passing through a nuclear reactor core, cooling the nuclear fuel, to act as a coolant, on the other hand it accumulates in the pressure vessel in play moderated neutrons role, acting as moderator.
Water quality monitoring sampling system:
Adding chemical system: under normal circumstances, for adding hydrazine, hydrogen, pH control agents to the primary coolant system, the main purpose is to remove and reduce coolant oxygen, high oxygen water suppression equipment wall corrosion (usually at a high temperature oxygen with hydrogen, especially at low temperatures during startup of a nuclear reactor with added hydrazine oxygen); when the nuclear reactor control rods stuck for some reason can not shutdown time by the the system can inject the nuclear reactor neutron absorber (such as boric acid solution), emergency shutdown, in order to ensure the safety of nuclear submarines.
Water system: a loop inside the water will be reduced at work, such as water sampling and analysis, equipment leaks, because the shutdown process cooling water and reduction of thermal expansion and contraction.
Equipment cooling water system:
Pressure safety systems: pressure reactor primary coolant system may change rapidly for some reason, the need for effective control. And in severe burn nuclear fuel rods, resulting in a core melt accident, it is necessary to promptly increase the pressure. Turn the regulator measures the electric, heating and cooling water. If necessary, also temporary startup booster pump.
Residual Heat Removal System: reactor scram may be due to an accident, such as when the primary coolant system of the steam generator heat exchanger tube is damaged, it must be urgently closed reactors.
Safety Injection System: The main components of this system is the high-pressure injection pump.
Radioactive waste treatment systems:
Decontamination Systems: for the removal of radioactive deposits equipment, valves, pipes and accessories, and other surfaces.
Europe, the United States and Russia and other countries related to aircraft carriers, submarines, icebreakers, nuclear-powered research aircraft, there are lots of achievements use of nuclear energy, it is worth analysis. However, nuclear reactor technology, rocket ships and the former are very different, therefore, requires special attention and innovative research. Must adopt a new new design techniques, otherwise, fall into the stereotype, it will avail, nothing even cause harm Aerospace.

60 years the United States has successfully developed polyimide fibers, it has highlighted the high temperature, radiation-resistant, fire-retardant properties.
[ "4" cosmic radiation resistant clothing design multifunctional anti-aging, wear underwear] ① comfort layer: astronauts can not wash clothes in a long flight, a lot of sebum, perspiration, etc. will contaminate underwear, so use soft, absorbent and breathable cotton knitwear making.
② warm layer: at ambient temperature range is not the case, warm layer to maintain a comfortable temperature environment. Choose warm and good thermal resistance large, soft, lightweight material, such as synthetic fibers, flakes, wool and silk and so on.
③ ventilation and cooling clothes clothes
Spacesuit
In astronaut body heat is too high, water-cooled ventilation clothing and clothing to a different way of heat. If the body heat production more than 350 kcal / h (ventilated clothes can not meet the cooling requirements, then that is cooled by a water-cooled suit. Ventilating clothing and water-cooled multi-use compression clothing, durable, flexible plastic tubing, such as polyvinyl chloride pipe or nylon film.
④ airtight limiting layer:
⑤ insulation: astronaut during extravehicular activities, from hot or cold insulation protection. It multilayer aluminized polyester film or a polyimide film and sandwiched between layers of nonwoven fabric to be made.
⑥ protective cover layer: the outermost layer of the suit is to require fire, heat and anti-space radiation on various factors (micrometeorites, cosmic rays, etc.) on the human body. Most of this layer with aluminized fabric.

The legibility of an encrypted message does not just depend on the complexity of the encryption algorithm, but also on the placement of the data of the message.
The Discreet Cosine Transform is a mathematical technique. In the case of the JPEG compression, a DCT is used to describe a finite set of patterns, called macroblocks, that could be described as the 64 character making up the JPEG image, adding lumo and chroma values as ‘intonation’.
If an image is compressed correctly, its macroblocks become ‘invisible’. The incidental trace of the macroblocks is generally ignored as artifact or error.
Keeping this in mind, I developed DCT. DCT uses the esthetics of JPEG macroblocks to mask its secret message as error. The encrypted message, hidden on the surface of the image is only legible by the ones in the know.

Hackerspace Hack42 is proudly hosting a new artist-in-residence. Dr. Vera K. Wilde (PhD PoliSci) is a (former) Harvard Kennedy School researcher. She is working on re-branding the Dark-Web to the EDTR-web, a place for Expressing, Dissenting, Teaching and Resisting.
The EDTR-web is using technologies like TOR and encrypted communications tools to create a place of freedom where centralised power cannot reach.
Vera will be using arts (oil painting and songwriting) as well as writing and political science methods to define and develop the EDTR-web as a social space and technological phenomenon.
Vera's third photo-shoot, in which we get to play with some theatrical props and explore extreme opposites.
Special thanks go to Moem for mixing up a batch of red paint and for producing the mad-mad-mad bloody special FX on the baseball-bat.
