2. Great poster

It brought me to tears. That should be everywhere.

4. He also laid down the foundations for the entire field of computer science

His research into finite-state automata is still, 70 years later, the definitive work in the field.

5. Turing helped save the world from Nazi oppression

His reward?

To be treated as a criminal for the rest of his life because of a harmless and immutable characteristic.

K&R.

7. Thank you for this. There are members of our own DU community who'll be remembered as heroes

in this struggle, right along with Alan Turing. This illogical, mean-spirited marginalization and outright cruel persecution of our absolute equals (and in many cases, our betters, for their courage) has to end. It's just wrong.

8. Leonardo da Vinci

From Wikipedia, the free encyclopedia


Salai as John the Baptist (c. 1514)—Louvre

Leonardo di ser Piero da Vinci, (April 15, 1452 – May 2, 1519), was an Italian polymath: painter, sculptor, architect, musician, scientist, mathematician, engineer, inventor, anatomist, geologist, botanist and writer. Leonardo has often been described as the archetype of the Renaissance man, a man whose unquenchable curiosity was equaled only by his powers of invention.<1> He is widely considered to be one of the greatest painters of all time and perhaps the most diversely talented person ever to have lived.<2> According to art historian Helen Gardner, the scope and depth of his interests were without precedent and "his mind and personality seem to us superhuman, the man himself mysterious and remote".<1>

Personal life

Within Leonardo's lifetime, his extraordinary powers of invention, his "outstanding physical beauty", "infinite grace", "great strength and generosity", "regal spirit and tremendous breadth of mind" as described by Vasari,<52> as well as all other aspects of his life, attracted the curiosity of others. One such aspect is his respect for life evidenced by his vegetarianism and his habit, described by Vasari, of purchasing caged birds and releasing them.<53><54>

Leonardo had many friends who are now renowned either in their fields or for their historical significance. They included the mathematician Luca Pacioli,<55> with whom he collaborated on a book in the 1490s, as well as Franchinus Gaffurius and Isabella d'Este. Leonardo appears to have had no close relationships with women except for his friendship with Isabella d'Este. He drew a portrait of her while on a journey which took him through Mantua, and which appears to have been used to create a painted portrait now lost.<10>

Beyond friendship, Leonardo kept his private life secret. His sexuality has been the subject of satire, analysis, and speculation. This trend began in the mid-16th century and was revived in the 19th and 20th centuries, most notably by Sigmund Freud.<56>

Leonardo's most intimate relationships were perhaps with his pupils Salai and Melzi, Melzi describing Leonardo's feelings for him as both loving and intensely passionate. It has been claimed since the 16th century that these relationships were of a sexual or erotic nature. Court records of 1476, when he was aged twenty-four, show that Leonardo and three other young men were charged with sodomy, and acquitted.<9> Since that date much has been written about his presumed homosexuality and its role in his art, particularly in the androgyny and eroticism manifested in John the Baptist and Bacchus and more explicitly in a number of erotic drawings.<57>

A hero betrayed by his own country.

17. I thought that the Naval Enigma code wasn't broken

A captured machine allowed them to decrypt the submarine traffic. The Naval machine had an extra code wheel, which increased the permutations significantly.

The Nazis made one big mistake. Every message ended with Heil H..... It was a built in crib for the decoders.

19. Just after the war Wittgenstein and Turing had protracted discussions at

the Moral Sciences Club at Cambridge attended by
Wittgenstein's students. For some reason Turing
was unable to attend for a period of time and
Wittgentein dismissed the class saying, "Nothing
of significance could be discussed without the
presence of Mr. Turing"

20. I'd read about him before in connection with the "Turing machine"

http://en.wikipedia.org/wiki/Turing_machine

But I never heard about his prosecution, punishment, or suicide. What a terrible story!

And what an excellent poster!
