Turing Bombe rebuild. This is not a computer, it is an electromechanical testing machine, used for finding the rotor settings of the Enigma machine, using trial-and-error.
Cryptography is used to secure the transactions and to control the creation of new coins. Put in another way, cryptocurrency is electricity converted into lines of code with monetary value. In the simplest of forms, cryptocurrency is digital currency. XenixCoin is also called cryptocurrency or digital currency and is basically a way to pay without the involvement of a third-party broker. Visit :: xenixcoin.com/cryptocurrency

This is an image of fol. Loose note 1, 1r from University of Pennsylvania LJS 186: Reverendi Patris Adami Adamandi disquisitiones physicomathematicae, by Kochánski, Adam, 1631-1700, Salvini, Anton Maria, 1653-1729, from Florence, dated to 1667-1668.
LJS 186 is a collection of scientific treatises with an emphasis on mathematical demonstration by the students of Adamus Adamandus (pseudonym of Adam Kochánski) at the Collegio Florentino, the Jesuit college in Florence. The third treatise, on underwater navigation, is described as a demonstration by Antonio Maria Salvini, a student at the Collegio from 1665 to 1669. Other treatises address fluid mechanics, perpetual motion, the possibility of human flight with mechanical wings, communication over distance with telescopes and lanterns, improvements in mechanical timekeeping, and the geometry of cross forms.

Michele Reilly is a scientist, an artist, and a systems thinker whose work resists easy classification. She trained in architecture and art at Cooper Union, where she began building intelligent machines and quickly became fascinated by the logic behind them. That curiosity drew her into mathematics, cryptography, macroeconomics, and eventually quantum physics. Her path has been shaped less by credentials than by the depth of her questions.
At MIT, where she teaches in the Department of Mechanical Engineering, Michele works at the intersection of computation and the structure of spacetime. She explores how information flows through the universe, drawing from Claude Shannon’s foundational theories and extending them into the quantum realm. Her research is ambitious, but it is rooted in careful thinking. She is not interested in speculation for its own sake. She wants to know what can be built, what can be measured, and what will last.
In 2016, she co-founded Turing, a quantum technology startup focused on building portable quantum memories and tools for long-distance quantum communication. She works closely with physicist Seth Lloyd on designing the scalable, robust systems needed to move quantum computing from theory into practice. The work is intricate and deliberate, building slowly toward a future that she sees as both beautiful and unfamiliar.
Michele is also a storyteller. Her science fiction series Steeplechase has received awards at Cannes and other international festivals. It reflects her belief that narrative and science are not separate pursuits, but parallel ways of exploring the unknown. In her teaching, she brings these strands together, guiding students through exercises that combine quantum theory, creative writing, and world-building. One of her courses, supported by MIT’s Center for Art, Science and Technology, invites students to imagine speculative futures grounded in scientific inquiry.
On her arm is a tattoo of Alan Turing. It is not ornamental. It is a quiet tribute to a thinker whose life and work continue to shape her own. Turing’s dedication to truth, structure, and the ethical weight of technology is a constant presence in her thinking. She carries it with her, quite literally.
The portrait above was made at The Interval at the Long Now Foundation in San Francisco. Michele is seated beside a polished table that reflects her image. Behind her stands the Orrery, a planetary model designed to keep time for ten thousand years. The setting reflects the spirit of her work. She is grounded in the present but always thinking forward, asking how we might live in ways that honor complexity, care, and continuity. She does not speak often about legacy. She speaks about attention, about precision, and about the discipline of staying with difficult questions until they begin to yield something real.
way way way before RSA, AES, Triple-DES ...

Mike took this photo during our visit to the Discover Greenwich Visitor Centre. This exhibit provides some information on the Old Royal Naval College:
Royal Naval College
The Royal Naval College opened on 1 February 1873. Its aim was to provide 'the highest possible instruction in all branches of theoretical and scientific study' necessary to the Navy at a time of rapidly changing technology. The first President, Vice-Admiral Sir Astley Cooper Key, believed that officers should be highly trained to provide the right leadership qualities. The senior training staff and directors of study were the foremost experts in their fields, further reinforcing the rigorous academic standards. The College quickly became the most highly rated naval officers' training college in Europe. As its reputation grew, students from navies around the world came to study in Greenwich, with officers from Russia, Japan and China among the first arrivals.
Students ranged in rank from Acting Sub-Lieutenant to Captain. There were also Royal Marines Officers, dockyard apprentice scholars and Merchant Marine officers. Later, selected Army and Air Force officers joined the Naval Staff Courses as well as officers from many other countries.
Occasions
In 1939, the restored Painted Hall was reinstated as the Officers' Mess. During term time the College held regular guest nights when nearly 400 sat down to dinner. The setting, with long rows of polished tables and the silver gleaming under the light of the candlesticks, provided a spectacle that no other mess could rival.
Many distinguished visitors were entertained. For example, in 1942 Winston Churchill attended a dinner with US government personnel and Senior Naval Staff. In January 1946 the Painted Hall was chosen for the first dinner of the newly formed United Nations. Another memorable occasion was the 150th anniversary of the Battle of Trafalgar on 21 October 1955, which was attended by the Queen and the Duke of Edinburgh.
The Royal Naval College courses were demanding so it was important for students to have time off, and leisure activities were encouraged. A variety of sports were played, including squash (using the courts then in this building), hockey, cricket, croquet and tennis. Social activities included a thriving dramatic society, which staged numerous plays, billiards, Highland dancing and skittles in the Victorian skittle alley beneath Upper Grand Square.
The War Years
World War I saw a change of emphasis in the courses offered at the Royal Naval College. It was used partly as a barracks and partly for experimental scientific work, including the production of vaccines. The end of the war brought further changes and considerable expansion, including the addition of History and English departments and the creation of a Royal Naval Staff College in 1919.
The outbreak of World War II in 1939 changed the College's main role to providing rapid training of 'hostilities only' officers with additional courses in cryptography, meteorology, navigation, air intelligence and current affairs. Nearly 27,000 officers passed through the College during the war years, including 14,000 from the Royal Naval and Royal Naval Volunteer Reserves and more than 8,000 WRNS officers (Women's Royal Naval Service).
After 1945 the College expanded its courses in engineering and science, including for the first time nuclear technology.

Everything cleared out once Sammy hoisted away the drone. Once she flew away, her losers lost their guts, making them easy to take down. Some were able to give us the slip, though. They aren't an issue, though. There's injured to attend to. It's stupid lucky there's just that: injuries. Everyone here is probably traumatized for a long time, but at least they get to see tomorrow. I got to tending the injured, one looking like it was Abe. The one kid with the rifle clocked him on the head, I think. I help him up off the ground as he brushes the dirt off his suit. He says to me "Weird uniform for a mail lady."I just chuckle a bit. First real time I'm actually talking to him. He's an alright guy. Don't see what Tim has such a problem with. About 10minuted later we're all out in front of the museum, officers patrolling around the display sets of old cannons and missile launchers. Next to the cannon was Arnold Patton, looking understandably mad.
"$15 million of hardware! Just flew away out the damned because of that bitch!"
"What, were you gonna sell that to psychopaths in suits of armor too?"
"Y'know what ya little loser, if you did your job right the first time back at city hall this wouldn't have happened! If people die because she has that drone, It's YOUR fault!"
"Why don't you--"
"Both of you just shut up already! Pointing fingers and accusing eachother isn't gonna stop Spinneret from whatever the hell she's gonna do! Now, Mr. Patton, I guess that drone Spinneret just flew off with wasn't just a mockup?"
"*sigh* No. Don't do mockups. I prefer giving people the real deal."
"And since it's a drone, It's remote controlled, and possibly remote activated?"
"YEAH! And y'know what, I have the controller right here! I can turn that sucker on and have it fly right back--"
"No! If you fly it back, we won't find Spinneret! We gotta use the drone to track her down. That remote activation might help."
"Well, a drone's just a big RC toy, so it uses radio waves of sorts, right? Maybe we can track those waves somehow to wherever Spinneret landed."
"Huh. Guess you're a detective for a reason, Arlington. Not bad."
"Thanks...Robin."
"Alright then! Arnold, just turn the Drone on, don't actually fly it. A signal should be sent to it giving us a trail. Robin, the cryptographic Sequencer should follow that signal, right?"
"Waaaay ahead of you."
Tim took out the sequencer and got to work. Man, that sequencer was always strange.I know how alot of our gizmos work, but this thing...I really don't know. Still, I don't really care how it works. As long as it helps us find Sammy before she does something stupid with that drone. I love it. I can't help but wonder, though. Just what does Sammy have planned? This stuff with attacking City Hall and stealing fancy drones...really high profile for her...Just makes you ask what's next....

Here I'm sniffing the NHBadge's SPI bus to demonstrate that radio settings are exposed on the bus. For radio chips such as the CC2420 that implement cryptography internally, keys are exposed on this bus.
