After almost eighteen years of deceptive silence, Brazen is back with Distance, an ambitious indie-rock epic where melancholic modulations and vocal harmonies intertwine on a soaring instrumental carpet. The eight tracks that make up the album are characterised by refined songwriting, carried by an epic breath that makes each track a journey in its own right. Composed, arranged and recorded remotely between London and Geneva over the course of almost a decade, the album is as musically polished as it is rich in narrative twists. The meticulous care taken in its conception gives it a timeless character that in no way detracts from its emotional intensity.
Testing out a new DIY LED-onna-stick arrangement. Still need to get the timing right on the pulse-width modulation.

I'm back from my yacht trip with the fabulous Sadie Peckham!
I'll be hard at work again tomorrow, at No. 1 Westmoreland Mews. This is the 'notorious address in West One' where The Salon is located: my high-class bordello, catering exclusively for the nobility and gentry. The Salon is entirely staffed by a team of happily-married, blue-blooded Aristocratic Ladies - shameless hotwives and cuckoldresses all!!
It never ceases to amuse me to see how naturally-adapted the upper-class English Lady is to a life of unrestrained depravity and corruption. How easily these snooty and entitled snobs pander to the Gomorran vices of their customers! And with what eagerness do their adoring husbands flock to watch their spouses' descent into the deepest depths of debauchery. It seems as if we have uncovered a hitherto unexplored psychological truth in the love lives and sexuality of our ruling class!!
As you all know, a harlot must dress as a harlot - it's what our clients expect. But the language of transactional lust has many modulations. Teaming this crisply-tailored jacket with my tarty PVC (vinyl) skirt and heels is the kind of fashion statement that always makes their Lordships stiff with anticipation!
Woo Hoo! It'll be such fun to be back at work!
Toodle Pip! Love and Kisses to All!!!

Messier 3 (M3 or NGC 5272) is a globular cluster of stars in the northern constellation of Canes Venatici. It was discovered by Charles Messier on May 3, 1764, and resolved into stars by William Herschel around 1784. Since then, it has become one of the best-studied globular clusters. Identification of the cluster's unusually large variable star population was begun in 1913 by American astronomer Solon Irving Bailey and new variable members continue to be identified up through 2004.
Many amateur astronomers consider it one of the finest northern globular clusters, following only Messier 13. M3 has an apparent magnitude of 6.2, making it a difficult naked eye target even with dark conditions. With a moderate-sized telescope, the cluster is fully defined. It can be a challenge to locate through the technique of star hopping, but can be found by looking almost exactly halfway along an imaginary line connecting the bright star Arcturus to Cor Caroli. Using a telescope with a 25 cm (9.8 in) aperture, the cluster has a bright core with a diameter of about 6 arcminutes and spans a total of 12 arcminutes.
This cluster is one of the largest and brightest, and is made up of around 500,000 stars. It is estimated to be 8 billion years old. It is located at a distance of about 33,900 light-years away from Earth.
Messier 3 is located 31.6 kly (9.7 kpc) above the Galactic plane and roughly 38.8 kly (11.9 kpc) from the center of the Milky Way. It contains 274 known variable stars; by far the highest number found in any globular cluster. These include 133 RR Lyrae variables, of which about a third display the Blazhko effect of long-period modulation. The overall abundance of elements other than hydrogen and helium, what astronomers term the metallicity, is in the range of –1.34 to –1.50 dex. This value gives the logarithm of the abundance relative to the Sun; the actual proportion is 3.2–4.6% of the solar abundance. Messier 3 is the prototype for the Oosterhoff type I cluster, which is considered "metal-rich". That is, for a globular cluster, Messier 3 has a relatively high abundance of heavier elements.

The Pulsemonger is a one of a kind design by me. It takes an input signal, squares it up, divides it by 2 (the sub-octave), and sends each pitch through individual pulse width modulator circuits that generates synth like tones. With the internal shapeable triangle LFO chorus and sci-fi sounds can be produced. The pulse width is variable from 1-50% and each can be externally controlled via the 1/4" input jacks.

A Casa de Mateus é mandada construir na primeira metade do século XVIII por António José Botelho Mourão, 3º Morgado de Mateus. Substitui-se à casa da família já existente no local em inícios do século XVII. Em 1911 é classificada como Monumento Nacional.
A arquitectura barroca, de gosto italiano, é atribuída a Nicolau Nasoni pela coerência do estilo e semelhança com outras obras de sua autoria. Segundo Robert Smith, especialista na sua obra, o arquitecto terá dedicado à construção da Casa, ou pelo menos à sua fachada central e decoração, os anos entre 1739 a 1743.
Para além do esplendor barroco da fachada principal e da riqueza da decoração, composta por cimalhas curvas, frontões, pináculos e estatuária, impressiona a racionalidade da planta e o rigor da métrica e da modulação.
A planta inscreve-se num rectângulo, e divide-se em dois quadrados vazados ao centro, que criam várias alas e compõem dois pátios ligados entre si por grandes aberturas no piso térreo. O pátio frontal é aberto libertando a vista da fachada principal recuada e voltada a poente, e o posterior é encerrado, e definem através dos grandes vãos do rés-do-chão um eixo central de perspectiva que atravessa toda a construção, e constitui um enfiamento de expressão clássica e grande harmonia.
O acesso ao piso nobre faz-se por duplas escadarias que se repetem nas fachadas transversais dos dois pátios, duas a poente e uma a nascente, e acentuam a simetria e o movimento barroco de toda a ornamentação.
No 1º andar, entre os pátios e com fachadas sobre ambos, ao centro da construção e definindo a linha de união dos dois quadrados que compõem a planta, localiza-se o Salão de Entrada. Dá acesso a norte e a sul, respectivamente à Biblioteca e ala de quartos, e à Sala do Tijolo e ala das salas. As duas alas são ligadas entre si no topo nascente através de uma ala com quartos que dá acesso ao Coro da Capela.
Os vinhos são DIVINOS e os jardins magníficos!

The Matthew House is ordered to be built in the first half of the eighteenth century by Antonio José Botelho Mourao, 3rd Morgado de Mateus. Replaces up to the family home already on site in the early seventeenth century. In 1911 is classified as a National Monument.
The baroque architecture of Italian style, is attributed to Nasoni consistency of style and resemblance to other works of authorship. According to Robert Smith, an expert in his work, the architect will be devoted to building the house, or at least its central facade and decor, the years between 1739 to 1743.
Apart from the baroque splendor of the main façade and wealth of decoration, consisting of curved cornice, gables, spiers and statuary, impresses the rationality and accuracy of the plant and metric modulation.
The plant is part of a rectangle and divided into two quadrants in the center, creating several wards and consist of two courtyards connected by large openings on the ground floor. The front patio is open, releasing the rearward view of the main facade and facing the west, and the latter is closed, and define through large openings in the ground-floor view of a central axis running through the building, and is a string of classical expression and great harmony.
Access to the first floor is by twin staircases that are repeated on the facades of the two cross courts, two to the west and east, and emphasize the symmetry and movement of all the Baroque ornamentation.
On the 1st floor, between the courts and on both fronts, the center of the building and defining the line of union of the two squares that make up the plant, located in the Entrance Hall. Provides access to the north and south respectively to the library and ward rooms, and room of the Brick and ward rooms. The two wings are linked together through spring at the top of a wing with rooms that gives access to the Chapel Choir.
The wines are magnificent gardens and DIVINE!
I always prefer photographing in available light – or Rembrandt-light I like to call it – so you get the natural modulations of the face. It makes a more alive, real, and flattering portrait.

[ Compulsory note: I did something here that I never do -- replaced a photo/post. Explanation: I uploaded this while taking a walk recently, or tried to, rather. No Wi-Fi [was in semi-Rural Texas at the time] and 0 phone data availability. Anyway, I accidentally uploaded the same image twice. Shockingly, I didn't go for twenty-three identical images or more [I am joking].
SO, instead of moving forward, ignoring the identical twins of my stream, AND to keep myself from just deep-sixing it [that wouldn't be very nice at all ;], I subbed a BW image shot at approx. same time and local.
Appreciate your understanding. Prost.

A good Saturday afternoon with wine, sun and ABBA
The greatest pop band ever in existence is back. It's like saying Elvis is in fact alive or Bowie faked his death (which he totally did) or Prince had a twin who is also a genius and still alive living as a recluse playing funk or Beatles recorded secret album in 1967 which just been found.
Favourite ABBA song?
impossible
but let's say I need to pick one for aliens to show them what ABBA thing is?
Ok I'll go with that one, it's just because I know, no strike that, my body knows (skin and all) , every note every shade of the keyboard track every voice modulation of every second of it, all of which is in its perfect place
Choro (Portuguese pronunciation: [ˈʃoɾu], "cry" or "lament"), popularly called chorinho ("little cry" or "little lament"), is a Brazilian popular music instrumental style. Its origins are in 19th century Rio de Janeiro. In spite of the name, the style often has a fast and happy rhythm, characterized by virtuosity, improvisation, subtile modulations and full of syncopation and counterpoint. Choro is considered the first urban popular music typical of Brazil.
Originally choro was played by a trio of flute, guitar and cavaquinho (a small chordophone with four strings). Other instruments commonly played in choro are the mandolin, clarinet, saxophone, trumpet and trombone. These melody instruments are backed by a rhythm section composed of guitar, 7-string guitar (playing bass lines) and light percussion, such as a pandeiro. The cavaquinho appears sometimes as a melody instrument, other times as part of the rhythm.
Structurally, a choro composition usually has three parts, played in a rondo form: AABBACCA, with each section typically in a different key (usually the tonal sequence is: principal key->relative mode->sub-dominant key). There are a variety of choros in both major and minor keys.
In the 19th century, choro resulted from the style of playing several musical genres (polka, schottische, waltz, mazurka and habanera) by carioca musicians, who were already strongly influenced by African rhythms, principally the lundu and the batuque. The term “choro” was used informally at first to refer to the style of playing, or a particular instrumental ensemble, (e.g. in the 1870s flutist Joaquim Antônio da Silva Callado formed an ensemble called "Choro Carioca", with flute, two guitars and cavaquinho), and later the term referred to the music genre of these ensembles. The accompanying music of the Maxixe (dance) (also called "tango brasileiro") was played by these choro ensembles. Various genres were incorporated as subgenres of choro such as "choro-polca", "choro-lundu" "choro-xote" (from schottische), "choro-mazurca", "choro-valsa" (waltz), "choro-maxixe", "samba-choro", "choro baião".
Just like ragtime in the United States, tango in Argentina and habanera in Cuba, choro springs up as a result of influences of musical styles and rhythms coming from Europe and Africa.
In the beginning (by the 1880s to 1920s), the success of choro came from informal groups of friends (principally workers of postal/telegraphic service and railway) which played in parties, pubs (botecos), streets, home balls (forrobodós), and also the large success of musical scores of Ernesto Nazareth, Chiquinha Gonzaga and others pianists, published by print houses. By the 1910s, many of the first Brazilian phonograph records are choros.
Much of the mainstream success (by the 1930s to 1940s) of this style of music came from the early days of radio, when bands performed live on the air. By the 1950s and 1960s it was replaced by urban samba in radio, but was still alive in amateur circles called "rodas de choro" (choro gatherings in residences and botecos), the one most famous was the "roda de choro" in the house of Jacob do Bandolim, in Jacarepaguá, and the "roda de choro" in the pub "suvaco de cobra" in the Penha.
In the late 1970s there was a successful effort to revitalize the genre in the mainstream, through TV-sponsored nation-wide festivals in 1977 and 1978, which attracted a new, younger generation of professional musicians. Thanks in great part to these efforts, choro music remains strong in Brazil. More recently, choro has attracted the attention of musicians in the United States, such as Mike Marshall and Maurita Murphy Mead, who have brought this kind of music to a new audience.
Most Brazilian classical composers recognize the sophistication of choro and its major importance in Brazilian instrumental music. Radamés Gnattali said it was the most sophisticated instrumental popular music in the world. Heitor Villa-Lobos defined choro as the true incarnation of Brazilian soul. Notably, both composers had some of their music inspired by choro, bringing it to the classical tradition. The French composer Darius Milhaud was enchanted by choro when he lived in Brazil (in 1917) and he composed the ballet Le Boeuf sur le toit, in which he quotes close to 30 Brazilian tunes.
According to Aquiles Rique Reis (a Brazilian singer), ”Choro is classical music played with bare feet and callus on the hands”

Radioteletype (RTTY) is a telecommunications system consisting originally of two or more electromechanical teleprinters in different locations connected by radio rather than a wired link. Radioteletype evolved from earlier landline teleprinter operations that began in the mid-1800s. The US Navy Department successfully tested printing telegraphy between an airplane and ground radio station in 1922. Later that year, the Radio Corporation of America successfully tested printing telegraphy via their Chatham, Massachusetts, radio station to the R.M.S. Majestic. Commercial RTTY systems were in active service between San Francisco and Honolulu as early as April 1932 and between San Francisco and New York City by 1934. The US military used radioteletype in the 1930s and expanded this usage during World War II. From the 1980s, teleprinters were replaced by personal computers (PCs) running software to emulate teleprinters.
The term radioteletype is used to describe both the original radioteletype system, sometimes described as "Baudot", as well as the entire family of systems connecting two or more teleprinters or PCs using software to emulate teleprinters, over radio, regardless of alphabet, link system or modulation.
In some applications, notably military and government, radioteletype is known by the acronym RATT (Radio Automatic Teletype).
Steam yacht Thelma, photographed in 1904. My colorization of an image in the Library of Congress archive (Detroit Publishin Co. collection).
Three years later Thelma made made history. The world´s first ship-to-shore broadcast was made from the yacht.
Electrical World reported on August 10, 1907:
"The first actual application of radio-telephony to practical work anywhere in the world was made at Put-in-Bay, in Lake Erie, during the week of July 15 to 20, in reporting the regatta of the Interlake Association. The Radio Telephone Company installed the De Forest wireless telephone on board of the cruiser yacht "Thelma," and also equipped a shore station at the Fox Dock at Put-in-Bay.
The "Thelma" followed the competing yachts around the course through most of the races and full and graphic accounts were telephoned into the shore station.
The greatest distance at which the reports from the yachts were heard and recorded was four miles, considered remarkable in view of the height of "Thelma's" spars and the power of the transmitter on board. Her equipment comprised a 220-volt generator of 1 kilowatt capacity, the DeForest oscillator and transmitter, and for the receiving apparatus an audion detector and "pan cake" form of syntonizer or tuner. Her aerial wires led through the roof of the wheelhouse to a small crossarm on top of the foremast and thence to a similar arm on the mainmast. Ground connection was at first made to the propeller shafts of her twin screws, but as this was found insufficient, more area was added by fastening two sheets of zinc to the yacht's hull at the bow.
The telephone dynamo was belted direct to the flywheel of her starboard engines, aft, and the rest of the radio apparatus was mounted on a small table in her main cabin convenient to all.
On shore 110-volt direct-current was available and this was transformed to 220 volts by a motor generator. The current was led through a rheostat and choke coils to the oscillator. Connected to this oscillator is a shunt circuit consisting of a condenser of peculiar construction and a primary coil, the exact number of turns of which could be varied at will to alter the tune or wave length of the electrical waves which were generated. A second coil within this primary had its upper end connected direct with the antennae or aerial wire, while its lower end led first through the microphone transmitter and thence to the earth plate. In this way the changes in resistance in the microphone produced by the modulations of the human voice directly affect the intensity of the high-frequency currents which are continually passing from the air wire to the ground plate. Inasmuch as the receiver instrument is affected exactly in proportion with the strength of the received electric waves, it is evident that every variation in the microphone resistance by the voice will be reproduced to the listening ear at the distant station by the vibration of the telephone diaphragm there. The microphone transmitter and the telephone receiver are exactly the same as used in the wire telephone, with which all are familiar. The "oscillator" and the "responder" are the only new and additional features, and the ether takes the place of the connecting wire.
Upon the finish of the regatta the telephone apparatus from the "Thelma" and the Put-in-Bay shore station was shipped to Toledo, where it is the intention of the Radio Telephone Company to install it permanently, where it can be in communication with other wireless telephone sets to be installed on vessels sailing Lake Erie. The Great Lakes offer, perhaps, the most promising field anywhere in the world for the first general application of this new invention to the needs of a merchant marine, and it is the intention of the company to at once enter this promising field."
Electrical World, August 10, 1907
About 7 years after Japan first staked it’s claim on Mercury and began mining the planet for Magnesium ore in an effort to curb reliance on the Russo-Sino Confederacy, the miners began taking scrap and creating maglev tracks and racing modified mining buggies and carts.
Within 20 years, the planetary pastime was refined and became increasingly dangerous, high tech, and profitable in its own right.
Bleeding edge technology not commonly used for terrestrial race applications became commonplace due to the lack of safety regulations pertaining to anything but the extraction of ore, an inherently risk seeking populace of thrill and adventure seekers now a generation deep.
Usually events were matched in three way heats to extend the festivities over the course of a full Mercurian day, or almost 2 months long on Earth. Pilots could expect to cross between scorching heat and bitterly freezing temperatures making the need for robust propulsion systems and life support systems paramount.
Here we see from left to right a Klandonian MKIV, adorned in spoilers which have less to do with producing downforce in a minimal atmosphere and more importantly work to transfer heat to or from the core of the vehicle depending on daytime or night time racing.
The Titan Industries Marauder is the only design produced from a manufacturer based on Mercury, and it’s record number of podium finishes is there to prove it. With a similarly complex set of veins and spoiler surfaces to mitigate heat and provide what aerodynamic modulation it can, it is slightly more delicate than the rest but otherwise supremely tuned to its environment.
Last in this heat is the Subaru Pleiades - a newly designed introduction from the Japanese automobile manufacturer. Hoping to stake a name for themselves in the fastest growing segment of industry and Motorsport entertainment, their cutting edge design was produced in partnership with Titan Industries but takes bold steps away from the reliance on heat sinks, diffusers, and spoilers, and focuses on a robust more rally like design. Not to be easily outdone, the vehicle shares the same power plant as the competitors but recirculates the heat in an ingenious internal channeling system that primes the fuel delivery system for more powerful combustion less reliant on external conditions and is thusly much more consistently performing in its output.
Events rarely end without one or two pilots meeting a glorious end by nightfall, but the prestige and a chance at the grand prize of a peripheral mining colony is too much for many young miners to pass up.
Here at one of the first officially recognized long distance tracks, Hi Bakudan Raceways (re-named after the tremendous and fatal collision during its inaugural race when it was simply known as The Path) all are expected to survive, but the odds are ever shifting.

........... and you think the world is in chaos today?..............
The New York Stock Exchange crashed in October 1929 throwing the nation into the grips of poverty and financial despair. 1930 was the beginning of the Great Depression. It would last a decade in the United States, where, at its nadir in 1933, 25 percent of all workers and 37 percent of all nonfarm workers were completely out of work. Some people starved; many others lost their farms and homes. Homeless vagabonds sneaked aboard the freight trains that crossed the nation. Dispossessed cotton farmers, the “Okies,” stuffed their possessions into dilapidated Model Ts and migrated to California in the false hope that the posters about plentiful jobs were true. Although the U.S. economy began to recover in the second quarter of 1933, the recovery largely stalled for most of 1934 and 1935. A more vigorous recovery commenced in late 1935 and continued into 1937, when a new depression occurred. The American economy had yet to fully recover from the Great Depression when the United States was drawn into World War II in December 1941. Because of this agonizingly slow recovery, the entire decade of the 1930s in the United States is often referred to as the Great Depression.
Socialism declared the Death of Capitalism; Hitler rose to power; From July 1936 to April 1939 Spain was ravaged by a Civil War, In 1931, the Japanese Kwangtung Army attacked Chinese troops in Manchuria. Ominous clouds of impending war loomed on the horizon. In the United States, the majority of its citizens were too preoccupied with trying to survive another day under the strains of the depression to notice.
But all of this drove technology forward: Radio was now the dominant mass medium in the so-called civilized world; the first commercial intercontinental airline flights began.

Meanwhile, Hitler's Nazi party gained power (in 1930), and soon led to the annexation of Austria (1938) and the invasion of Poland (1939), which drew France and Great Britain into World War II, despite the dithering of Neville Chamberlain. In June of 1940 the rapidly advancing German Army captured Paris. Franklin Delano Roosevelt is U.S. president (1932 into the next decade). Great Britain sees three kings in the decade: Edward VIII, George V, and George VI.

RADIO:
Although the origins of television can be traced back as far as 1873 the discovery of the photoconductivity of the element selenium by Willoughby Smith, the first regularly scheduled television service in the United States was not available until July 2, 1928 and yet then it was in its infancy and certainly not perfected and not a widely accepted form of media. Radio was the media of the time. Most Americans, although barely able to put food on the table or clothes on their backs, had some type of radio in their living quarters.
1932, November 7th - the First radio broadcast of "Buck Rogers" www.buck-rogers.com/radio_serial/
What followed was a whole host of Science fiction, mystery, comedy, westerns, detective and music programs. During the mid to late 30’s and 40’s millions of American families gathered around their radios in the evening listening to their favorite radio shows. Radio broadcasts continued well into the late 50’s when eventually television became readily accessible and affordable to most Americans.
A few of the earliest radio shows:
“Flash Gordon” – September, 1935: www.oldradioworld.com/media/Flash%20Gordon%201935-09-07%2...
“The Town Crier” 1929 - 1942: www.oldradioworld.com/media/The%20Town%20Crier%20Twenty%2...
“Sam Bass, Death Valley Days” 1930 – 1945: www.oldradioworld.com/media/Death%20Valley%20Days%201936-...
“The Aldrich Family” – 1939 - 1953: www.oldradioworld.com/media/The%20Aldrich%20Family%201952...

Notable events:
1931 - Empire State Building opens in New York City
1931, September – Japanese invade Manchuria
1932 - Ford introduces the Model B, the first low-priced car to have a V-8 engine
1933 - Franklin Delano Roosevelt sworn in as President; he is the last president to be inaugurated on
March 4.
1933, February - Less than a month after Hitler became chancellor, the Reichstag burns down. When the police arrive they find Marinus van der Lubbe on the premises. Upon being tortured by the Gestapo van der Lubbe confesses to starting the fire. However he denies that he was part of a Communist
Conspiracy. Hitler later gives orders that all leaders of the German Communist Party "will be
hanged that very night." Hermann Goering announces that the Nazi Party plans "to exterminate" German communists.
1934 Chancellor Dollfuss of Austria assassinated by Nazis. Hitler becomes führer. USSR admitted to League of Nations.
1934 - John Dillinger is killed in Chicago
1935 - Mussolini invades Ethiopia; League of Nations invokes sanctions. Roosevelt opens second
phase of New Deal in U.S., calling for social security, better housing, equitable taxation, and farm assistance. Huey Long assassinated in Louisiana.
1935, September - The Nuremberg Race Laws deprive German Jews of their rights of citizenship, giving them the status of "subjects" in Hitler's Reich. The laws also make it forbidden for Jews to marry or have sexual relations with Aryans or to employ young Aryan women as household help. The Nazis settle on defining a "full Jew" as a person with three Jewish grandparents. Those with less were designated as Mischlinge or a "mixed blood."
1937, May - the German passenger airship, the Hindenburg, catches fire and is destroyed while attempting to dock during a electrical storm at the Lakehurst Naval Air Station. Of the 97 people on board, 15 are killed along with people killed on the ground. The exact cause for this disaster is still unknown.
1936, August – The 1936 Summer Olympics officially known as Games of the XI Olympiad, are held in Berlin, Germany. Jesse Owens wins four gold medals: the 100m sprint, the long jump, 200m sprint and after he was added to the 4 x 100 m relay team, he won his fourth on August 9.
* Owens was allowed to travel with and stay in the same hotels as whites, while at the time blacks in many parts of the United States were denied equal rights. After a New York City ticker-tape parade of Fifth Avenue in his honor, Owens had to ride the freight elevator at the Waldorf-Astoria to reach the reception honoring him.......... a sad chapter in the history of the United States. Owens said, "Hitler didn't snub me – it was FDR who snubbed me. The president didn't even send me a telegram." On the other hand, Hitler sent Owens a commemorative inscribed cabinet photograph of himself. Jesse Owens was never invited to the White House nor were honors bestowed upon him by president Franklin D. Roosevelt (FDR) or his successor Harry S. Truman during their terms. In 1955, President Dwight D. Eisenhower honored Owens by naming him an "Ambassador of Sports."
1936 - Germans occupy Rhineland. Italy annexes Ethiopia. Rome-Berlin Axis proclaimed (Japan to join
in 1940). Trotsky exiled to Mexico.
1937 - Hitler repudiates war guilt clause of Versailles Treaty; continues to build German power. Italy withdraws from League of Nations. U.S. gunboat Panay sunk by Japanese in Yangtze River.
Japan invades China, conquers most of coastal area. Amelia Earhart lost somewhere in Pacific
on round-the-world flight. Picasso's Guernica mural – an abstract depicting the chaos and human calamity of the Spanish Civil War.
1938, November - The Kristallnacht or the "Night of Broken Glass" is a night when the Gestapo and the SS go through towns of Austria and smash the windows of Jewish occupations. Thousands of homes and businesses are ransacked, 91 Jews are murdered and 25,000 to 30,000 are arrested and placed in concentration camps.
1938, March - The Anschluss, Germany takes over Austria. The German speaking part of Austria wanted to unite with Germany and Hitler states that this was his purpose for the annexation of Austria. However, this is against the Treaty of Versailles.
1939, September - Nazi-Germany attacks Poland, essentially the beginning of World War II. Many
countries around Germany declared war on Germany but do not take overt action against the Third Reich. Recently, Adolf Hitler had agreed in the Munich Agreement that he would not invade Poland. Great Britain and Poland have a mutual aid treaty that requires either country to come to the aid of the other in the event of war. When Germany invades Poland, Britain (and the Commonwealth) is obligated to come to the aid of Poland by declaring war on Germany. The United States, however, does not officially declare war against Germany. Many countries rise up and voiced anger over Hitler’s betrayal but only Britain and the Commonwealth take overt actions to try and stop Hilter’s military aggression.
1939 - President Roosevelt, appears at the opening of the 1939 New York World's Fair, becoming the first President to give a speech that is broadcast on television. Semi-regular broadcasts air during the next two years
1940, August - The Battle of Britain begins. The German Luftwaffe attempts to take over British airspace and destroy the Royal Air Force with the intention of eventually invading England. Against all odds, Britain and The Royal Air Force resist the Luftwaffe aggression causing Hitler to abandon the idea of invading Britain and to turn his attention to Russia.
1940, March - "Lend/Lease" is the name of the program under which the US supplied the United Kingdom, the Soviet Union, China, France and other Allied nations with vast amounts of war material in return for military bases in Newfoundland, Bermuda, and the British West Indies. It
was intended to promote the defense of the US. This act also ended the neutrality of the United States.
1940, May (This picture) – A mostly vacant downtown area of St. Louis on an early Sunday
morning.
As this picture suggests, the United States lay basically asleep, as many Americans are either unaware , or prefer to ignore the ominous winds of war swirling all around them. In a few short months, the hammer would fall and Americans would find themselves anxiously gathered around their radios listening to the President of the United States announce:
“Yesterday, December 7th, 1941 - a date which will live in infamy - the United States of America was suddenly and deliberately attacked by naval and air forces of the Empire of Japan.
The United States was at peace with that nation and, at the solicitation of Japan, was still in conversation with its government and its emperor looking toward the maintenance of peace in the Pacific.
Indeed, one hour after Japanese air squadrons had commenced bombing in the American island of Oahu, the Japanese ambassador to the United States and his colleagues delivered to our Secretary of State a formal reply to a recent American message. And while this reply stated that it seemed useless to continue the existing diplomatic negotiations, it contained no threat or hint of war or of armed attack.
It will be recorded that the distance of Hawaii from Japan makes it obvious that the attack was deliberately planned many days or even weeks ago. During the intervening time, the Japanese government has deliberately sought to deceive the United States by false statements and expressions of hope for continued peace.
The attack yesterday on the Hawaiian islands has caused severe damage to American naval and military forces. I regret to tell you that very many American lives have been lost. In addition, American ships have been reported torpedoed on the high seas between San Francisco and Honolulu.
Yesterday, the Japanese government also launched an attack against Malaya.
Last night, Japanese forces attacked Hong Kong.
Last night, Japanese forces attacked Guam.
Last night, Japanese forces attacked the Philippine Islands.
Last night, the Japanese attacked Wake Island.
And this morning, the Japanese attacked Midway Island.
Japan has, therefore, undertaken a surprise offensive extending throughout the Pacific area. The facts of yesterday and today speak for themselves. The people of the United States have already formed their opinions and well understand the implications to the very life and safety of our nation.
As commander in chief of the Army and Navy, I have directed that all measures be taken for our defense.
But always will our whole nation remember the character of the onslaught against us.
No matter how long it may take us to overcome this premeditated invasion, the American people in their righteous might will win through to absolute victory.
I believe that I interpret the will of the Congress and of the people when I assert that we will not only defend ourselves to the uttermost, but will make it very certain that this form of treachery shall never again endanger us.
Hostilities exist. There is no blinking at the fact that our people, our territory and our interests are in grave danger.
With confidence in our armed forces - with the unbounding determination of our people - we will gain the inevitable triumph - so help us God.
I ask that the Congress declare that since the unprovoked and dastardly attack by Japan on Sunday, December 7th, 1941, a state of war has existed between the United States and the Japanese empire.”
From this day forward, life as American’s knew it, will be drastically and forever changed.
A partial view of one of the three apses of Florence's cathedral, Santa Maria del Fiore, from the bottom up.
I have been fascinated by the series of layers you can see, something like steps in a ladder climbing towards the sky, culminating with the curve surface of Brunelleschi bricks dome and the gilt copper sphere and cross crowning the whole structure (the lantern is hidden due to the curvature of the dome, from this point of view).
This view strikes me as another kind of visual counterpoint, the spiral canon - a canon whose theme at every repetition begins at a different pitch, creating a sort of ascending (or possibly descending - I do not know examples of this, though) musical spiral - or a ladder, indeed.
There are few examples of spiral canons, the most known being the ascending spiral canon in Bach's Musical Offering BWV 1079, which ia accompanied by the Latin motto Ascendenteque Modulatione ascendat Gloria Regis (As the keys ascend so may the glory of the king also ascend).
The spiral canon is one of the "musical traps" set by Bach for Frederick the Great, to whom the work is dedicated - with no flattery from the Author. The motto is related to the structure of the canon, which undeniably sports an ascending pitch progression - on the stave, at least. But the Royal Theme permeating the whole work - a tricky theme imposed upon Bach by Frederick himself for an impromptu display of his masterly contrapunctal arts - is so rich in chromaticism that, upon execution, one cannot really perceive the ascending modulation. I strongly suspect that this could be just a way to negate with music the letter of the Latin motto, getting into perspective Frederick's earthly power (possibly suggesting that the only King is not of this world) :-))

I knew nothing about the practical use of LED strip lights before this project. I've since discovered the concept of "pulse width modulation," or PWM. There's plenty of info on the net about it. What I observed was ghost imaging at high magnifications (>5X) and at shutter speeds of less than 1/400s. The "light tunnel" produces a lot of light, but I still had to use an ISO of 1000 at TV 1/400s and Av 5.6 at those high magnifications. The ghosting effect decreases to negligibility at lower magnifications of less than 2X and I was able to adjust exposure parameters such as reducing ISO and Tv. I did not notice any typical banding effects. I had installed a dimmer mechanism on the LED circuit, but will remove it to see if it affects anything.
I like the light that the "light tunnel" produces. Very soft and diffused.

Choro (Portuguese pronunciation: [ˈʃoɾu], "cry" or "lament"), popularly called chorinho ("little cry" or "little lament"), is a Brazilian popular music instrumental style. Its origins are in 19th century Rio de Janeiro. In spite of the name, the style often has a fast and happy rhythm, characterized by virtuosity, improvisation, subtile modulations and full of syncopation and counterpoint. Choro is considered the first urban popular music typical of Brazil.
Originally choro was played by a trio of flute, guitar and cavaquinho (a small chordophone with four strings). Other instruments commonly played in choro are the mandolin, clarinet, saxophone, trumpet and trombone. These melody instruments are backed by a rhythm section composed of guitar, 7-string guitar (playing bass lines) and light percussion, such as a pandeiro. The cavaquinho appears sometimes as a melody instrument, other times as part of the rhythm.
Structurally, a choro composition usually has three parts, played in a rondo form: AABBACCA, with each section typically in a different key (usually the tonal sequence is: principal key->relative mode->sub-dominant key). There are a variety of choros in both major and minor keys.
In the 19th century, choro resulted from the style of playing several musical genres (polka, schottische, waltz, mazurka and habanera) by carioca musicians, who were already strongly influenced by African rhythms, principally the lundu and the batuque. The term “choro” was used informally at first to refer to the style of playing, or a particular instrumental ensemble, (e.g. in the 1870s flutist Joaquim Antônio da Silva Callado formed an ensemble called "Choro Carioca", with flute, two guitars and cavaquinho), and later the term referred to the music genre of these ensembles. The accompanying music of the Maxixe (dance) (also called "tango brasileiro") was played by these choro ensembles. Various genres were incorporated as subgenres of choro such as "choro-polca", "choro-lundu" "choro-xote" (from schottische), "choro-mazurca", "choro-valsa" (waltz), "choro-maxixe", "samba-choro", "choro baião".
Just like ragtime in the United States, tango in Argentina and habanera in Cuba, choro springs up as a result of influences of musical styles and rhythms coming from Europe and Africa.
In the beginning (by the 1880s to 1920s), the success of choro came from informal groups of friends (principally workers of postal/telegraphic service and railway) which played in parties, pubs (botecos), streets, home balls (forrobodós), and also the large success of musical scores of Ernesto Nazareth, Chiquinha Gonzaga and others pianists, published by print houses. By the 1910s, many of the first Brazilian phonograph records are choros.
Much of the mainstream success (by the 1930s to 1940s) of this style of music came from the early days of radio, when bands performed live on the air. By the 1950s and 1960s it was replaced by urban samba in radio, but was still alive in amateur circles called "rodas de choro" (choro gatherings in residences and botecos), the one most famous was the "roda de choro" in the house of Jacob do Bandolim, in Jacarepaguá, and the "roda de choro" in the pub "suvaco de cobra" in the Penha.
In the late 1970s there was a successful effort to revitalize the genre in the mainstream, through TV-sponsored nation-wide festivals in 1977 and 1978, which attracted a new, younger generation of professional musicians. Thanks in great part to these efforts, choro music remains strong in Brazil. More recently, choro has attracted the attention of musicians in the United States, such as Mike Marshall and Maurita Murphy Mead, who have brought this kind of music to a new audience.
Most Brazilian classical composers recognize the sophistication of choro and its major importance in Brazilian instrumental music. Radamés Gnattali said it was the most sophisticated instrumental popular music in the world. Heitor Villa-Lobos defined choro as the true incarnation of Brazilian soul. Notably, both composers had some of their music inspired by choro, bringing it to the classical tradition. The French composer Darius Milhaud was enchanted by choro when he lived in Brazil (in 1917) and he composed the ballet Le Boeuf sur le toit, in which he quotes close to 30 Brazilian tunes.
According to Aquiles Rique Reis (a Brazilian singer), ”Choro is classical music played with bare feet and callus on the hands”

In the past i study Geology in University, i decided to create, through the help of Artificial Intelligence, some breathtaking landscapes resulting from the erosive action of water throughout geological cycles.
By changing certain parameters such as lithology, oxidation of minerals, different types of algae and the type of karstic modulation as well as local environmental conditions, these series of landscapes are the result of these attempts...
Jerusalem, Israel: Covered carelessly with an adhesive sheet of plastic, this poster was marred by a number of channel-shaped, air pockets, running randomly over its surface, but which provided the image with visually interesting modulations of the reflections of the warm, street lighting.
After requests to show the setup I used for the lighting of Streets of Barqa, here is a sketch of how I remember I connected the cables. The only reason I used my eLite Advanced 2 was due to a shortage of inputs and too short cables, will probably replace that as soon as I order more stuff from LifeLites if I do not dismantle the MOC before that. The "flicker flame" diodes did not like it's ordinary outputs however even at steady light (probably due to PWM modulation messing with the flickering diode's electronics?) so I had to use the non-controlled output for that.
The ModuLites are of the warm-white kind and using two + white interior walls gave quite a lot more light as can be seen on the building to the right.
I gladly recommend LifeLites to anyone who wants to light their MOCs! Just be careful with those fragile connectors...

There is a superhighway between the brain and GI system that holds great sway over humans
"There is a muscle that encircles the gut like a lasso when we are sitting… creating a kink in the tube," Giulia Enders explains in Gut: The Inside Story of Our Body's Most Underrated Organ. She calls the mechanism "an extra insurance policy, in addition to our old friends, the sphincters" (you have two sphincters – keep reading) and cites studies showing that squatters, with their unkinked guts, are less susceptible to haemorrhoids and constipation.Enders, a 25-year-old student at the Institute for Microbiology in Frankfurt, inside an underground public lavatory in central London. "Is there a toilet in this toilet?" she asks when she arrives. There is not, a barista tells her. The Victorian urinals, abandoned in the 1960s, have been converted into cafe with booths and stools, and no room for anything else.After a dash to a pub loo above ground, Enders talks with infectious energy about the wonder of the gut. She has been delighted to discover how many people share her fascination with a subject that can suffer for being taboo. "Even today in the taxi, I told the driver what I was doing and within about two minutes he was telling me about his constipation," she says in perfect English, which she owes to a year of study in the US. "And it's not just him. It's ladies with chic hair at big gala dinners, too. Everyone wants to talk about it."Enders first got noticed after a self-assured turn at a science slam in Berlin three years ago. Her 10-minute lecture went viral on YouTube, and now, weeks after completing her final exams as a doctoral student, she is a publishing sensation. Her book, called Darm Mit Charme ("Charming Bowels") in Germany, has sold more than 1.3 million copies since it came out last year. Rights have been sold to dozens of countries.
Her way into the gut is a lightness that some reviewers have found too childish or lacking in scientific rigour to be taken seriously. But there is something compelling and refreshing about her curiosity and popular approach. "When I read the research, I think, why don't people know about this – why am I reading about it in some paper or specialist magazine? It's ridiculous because everyone has to deal with it on a daily basis." After she explains the inspiration for her fixation (the suicide of an acquaintance who had had severe halitosis, and her own teenage skin condition, which turned out to have been caused by a wheat intolerance) Enders starts at the end of the digestive tract with what she calls the "masterly performance" that is defecation. "There is so much about the anus that we don't know," she says, reaching for a gluten-free chocolate chip cookie. "The first surprise is the sophistication of our sphincters… you know about the outer one because you can control it, but the inner one nobody knows about."
This inner opening is beyond our conscious control, releasing waste material into a sort of anal vestibule where, in Enders words, "a small taster" hits sensor cells that tell the body what it's dealing with and how to respond using the outer sphincter. This opening, and our mouths, are the recognisable and controllable ends of a system that, stretched out, would be almost as long as a bus. But it's the bits in between, and their link with the rest of our bodies, including our brains and emotions, that really interest Enders.
"Medical diagrams show the small intestine as a sausage thing chaotically going through our belly," she says. "But it is an extraordinary work of architecture that moves so harmonically when you see it during surgery. It's clean and smooth, like soft fabric, and moves like this." She performs a wavy, pulsating motion with her hands. Enders believes that if we could think differently about the gut, we might more readily understand its role beyond basic digestion – and be kinder to it. The great extent to which the gut can influence health and mood is a growing field in medicine. We speak of it all the time, whether we describe "gut feelings", "butterflies in our stomachs", or "pooing our pants" in fear, but popular understanding of this gut-brain axis remains low.
A primal connection exists between our brain and our gut. We often talk about a “gut feeling” when we meet someone for the first time. We’re told to “trust our gut instinct” when making a difficult decision or that it’s “gut check time” when faced with a situation that tests our nerve and determination. This mind-gut connection is not just metaphorical. Our brain and gut are connected by an extensive network of neurons and a highway of chemicals and hormones that constantly provide feedback about how hungry we are, whether or not we’re experiencing stress, or if we’ve ingested a disease-causing microbe. This information superhighway is called the brain-gut axis and it provides constant updates on the state of affairs at your two ends. That sinking feeling in the pit of your stomach after looking at your postholiday credit card bill is a vivid example of the brain-gut connection at work. You’re stressed and your gut knows it—immediately.
The enteric nervous system is often referred to as our body’s second brain. There are hundreds of million of neurons connecting the brain to the enteric nervous system, the part of the nervous system that is tasked with controlling the gastrointestinal system. This vast web of connections monitors the entire digestive tract from the esophagus to the anus. The enteric nervous system is so extensive that it can operate as an independent entity without input from our central nervous system, although they are in regular communication. While our “second” brain cannot compose a symphony or paint a masterpiece the way the brain in our skull can, it does perform an important role in managing the workings of our inner tube. The network of neurons in the gut is as plentiful and complex as the network of neurons in our spinal cord, which may seem overly complex just to keep track of digestion. Why is our gut the only organ in our body that needs its own “brain”? Is it just to manage the process of digestion? Or could it be that one job of our second brain is to listen in on the trillions of microbes residing in the gut?
Operations of the enteric nervous system are overseen by the brain and central nervous system. The central nervous system is in communication with the gut via the sympathetic and parasympathetic branches of the autonomic nervous system, the involuntary arm of the nervous system that controls heart rate, breathing, and digestion. The autonomic nervous system is tasked with the job of regulating the speed at which food transits through the gut, the secretion of acid in our stomach, and the production of mucus on the intestinal lining. The hypothalamic-pituitary-adrenal axis, or HPA axis, is another mechanism by which the brain can communicate with the gut to help control digestion through the action of hormones.
This circuitry of neurons, hormones, and chemical neurotransmitters not only sends messages to the brain about the status of our gut, it allows for the brain to directly impact the gut environment. The rate at which food is being moved and how much mucus is lining the gut—both of which can be controlled by the central nervous system—have a direct impact on the environmental conditions the microbiota experiences.
Like any ecosystem inhabited by competing species, the environment within the gut dictates which inhabitants thrive. Just as creatures adapted to a moist rain forest would struggle in the desert, microbes relying on the mucus layer will struggle in a gut where mucus is exceedingly sparse and thin. Bulk up the mucus, and the mucus-adapted microbes can stage a comeback. The nervous system, through its ability to affect gut transit time and mucus secretion, can help dictate which microbes inhabit the gut. In this case, even if the decisions are not conscious, it’s mind over microbes.
What about the microbial side? When the microbiota adjusts to a change in diet or to a stress-induced decrease in gut transit time, is the brain made aware of this modification? Does the brain-gut axis run in one direction only, with all signals going from brain to gut, or are some signals going the other way? Is that voice in your head that is asking for a snack coming from your mind or is it emanating from the insatiable masses in your bowels? Recent evidence indicates that not only is our brain “aware” of our gut microbes, but these bacteria can influence our perception of the world and alter our behavior. It is becoming clear that the influence of our microbiota reaches far beyond the gut to affect an aspect of our biology few would have predicted—our mind.
For example, the gut microbiota influences the body’s level of the potent neurotransmitter serotonin, which regulates feelings of happiness. Some of the most prescribed drugs in the U.S. for treating anxiety and depression, like Prozac, Zoloft, and Paxil, work by modulating levels of serotonin. And serotonin is likely just one of a numerous biochemical messengers dictating our mood and behavior that the microbiota impacts.
Most of us can relate to the experience of having butterflies in our stomach, or to a visceral gut-wrenching feeling, and how often are we told not to ignore our “gut-instinct” or “gut-feeling” when making a decision.
Even from our simple slang, it’s clear just how symbolically connected the gut is to our emotions. Now, there’s tangible proof to support these popular metaphors.
We all have a microbiome, and they are as unique as our neural pathways
Research has shown that the body is actually composed of more bacteria than cells. We are more bug than human! Collectively, these trillions of bacteria are called the microbiome. Most of those bacteria reside in our gut, sometimes referred to as the gut microbiota, and they play multiple roles in our overall health.
The gut is no longer seen as an entity with the sole purpose of helping with all aspects of digestion. It’s also being considered as a key player in regulating inflammation and immunity.
A healthy gut consists of different iterations of bacteria for different people, and this diversity maintains wellness. A shift away from “normal” gut microbiota diversity is called dysbiosis, and dysbiosis may contribute to disease. In light of this, the microbiome has become the focus of much research attention as a new way of understanding autoimmune, gastrointestinal, and even brain disorders.
The benefit of a healthy gut is illustrated most effectively during early development. Research has indicated just how sensitive a fetus is to any changes in a mother’s microbiotic makeup, so much so that it can alter the way a baby’s brain develops. If a baby is born via cesarean section, it misses an opportunity to ingest the mother’s bacteria as it travels down the vaginal canal. Studies show that those born via c-section have to work to regain the same diversity in their microbiome as those born vaginally. Throughout our lives, our microbiome continues to be a vulnerable entity, and as we are exposed to stress, toxins, chemicals, certain diets, and even exercise, our microbiome fluctuates for better or worse.
The gut as second brain
Our gut microbiota play a vital role in our physical and psychological health via its own neural network: the enteric nervous system (ENS), a complex system of about 100 million nerves found in the lining of the gut.
The ENS is sometimes called the “second brain,” and it actually arises from the same tissues as our central nervous system (CNS) during fetal development. Therefore, it has many structural and chemical parallels to the brain.
Our ENS doesn’t wax philosophical or make executive decisions like the gray shiny mound in our skulls. Yet, in a miraculously orchestrated symphony of hormones, neurotransmitters, and electrical impulses through a pathway of nerves, both “brains” communicate back and forth. These pathways include and involve endocrine, immune, and neural pathways.
At this point in time, even though the research is inchoate and complex, it is clear that the brain and gut are so intimately connected that it sometimes seems like one system, not two.
Our emotions play a big role in functional gastrointestinal disorders
Given how closely the gut and brain interact, it has become clear that emotional and psychosocial factors can trigger symptoms in the gut. This is especially true in cases when the gut is acting up and there’s no obvious physical cause.
The functional gastrointestinal disorders (FGIDs) are a group of more than 20 chronic and hard to treat medical conditions of the gastrointestinal tract that constitute a large proportion of the presenting problems seen in clinical gastroenterology.
While FGID’s were once thought to be partly “in one’s head,” a more precise conceptualization of these difficulties posits that psychosocial factors influence the actual physiology of the gut, as well as the modulation of symptoms. In other words, psychological factors can literally impact upon physical factors, like the movement and contractions of the GI tract, causing, inflammation, pain, and other bowel symptoms.
Mental health impacts gut wellness
In light of this new understanding, it might be impossible to heal FGID’s without considering the impact of stress and emotion. Studies have shown that patients who tried psychologically based approaches had greater improvement in their symptoms compared with patients who received conventional medical treatment.
Along those lines, a new pilot study from Harvard University affiliates Benson-Henry Institute for Mind Body Medicine at Massachusetts General Hospital and Beth Israel Deaconess Medical Center found that meditation could have a significant impact for those with irritable bowel syndrome and inflammatory bowel disease. Forty-eight patients with either IBS or IBD took a 9-week session that included meditation training, and the results showed reduced pain, improved symptoms, stress reduction, and the change in expression of genes that contribute to inflammation.
Poor gut health can lead to neurological and neuropsychiatric disorders
Vice-versa, poor gut health has been implicated in neurological and neuropsychiatric disorders. Disturbances in gut health have been linked to multiple sclerosis, autistic spectrum disorders, and Parkinson’s disease. This is potentially related to pro-inflammatory states elicited by gut dysbiosis-microbial imbalance on or inside the body. Additional connections between age-related gut changes and Alzheimer’s disease have also been made.
Further, there is now research that is dubbing depression as an inflammatory disorder mediated by poor gut health. In fact, multiple animal studies have shown that manipulating the gut microbiota in some way can produce behaviors related to anxiety and depression. (Maes, Kubera, Leunis, Berk, J. Affective Disorders, 2012 and Berk, Williams, Jacka, BMC Med, 2013).
Our brain’s health, which will be discussed in more depth in a later blog post, is dependent on many lifestyle choices that mediate gut health; including most notably diet (i.e., reduction of excess sugar and refined carbohydrates) and pre and probiotic intake.
The brain-gut connection has treatment implications
We are now faced with the possibility of both prevention and treatment of neurological/neuropsychiatric difficulties via proper gut health. On the flip side, stress-reduction and other psychological treatments can help prevent and treat gastrointestinal disorders. This discovery can potentially lead to reduced morbidity, impairment, and chronic dependency on health care resources.
The most empowering aspect to the gut-brain connection is the understanding that many of our daily lifestyle choices play a role in mediating our overall wellness. This whole-body approach to healthcare and wellness continues to show its value in our longevity, well-being, and quality of life: that both physical and mental health go hand-in-hand.
Germany, Hamburg, Harbour City, Magellan Terraces, a square covering about 5,000 square metres, similar to an amphitheatre & providing a fine view of the Traditional-Ship Harbour in the Harbour City. This square is an inviting place to linger & is also used for cultural events.
For almost one & a half century, since 1866, the Harbour at the “Sandtorwall” was used as a port for ships with all kinds of imports from around the world. With the increasing size of cargo ships & later the container giants, the ware house area was not able to handle the freighters any longer. The whole area started than to be changed, maintaining the historic structure & buildings, into today’s harbour city, housing offices, apartments, gastronomy, shops etc., the re-modulation of the harbour city will still go on for many years, including the never ending story of the philharmonic concert hall.
