Krawtchouk's Mind

A reader writes: "Central Europe Review is running an article on a gulag-condemned Soviet scientist whose contribution to the first computer is virtually unknown because of the Cold War mentality that infected much of society on both sides of the Iron Curtain. The story tells of how in 1937, American digital computer pioneer John Atanasoff came across a Myhailo Krawtchouk paper on a new method for finding approximate solutions to differential equations. Atanasoff tried sending a letter to him, but received no response. Krawtchouk had been attainted for giving a favorable review of the work of "enemies of the people" and shipped to Siberia for 20 years of gold mining, where he died four years later. Krawtchouk's biography gives a more detailed account of how Krawtchouk was labeled a "Polish spy" and "Ukrainian nationalist," stripped of his Academy of Sciences membership, and forced to sign a confession -- that he later retracted -- under torture and threats upon his family.

Actually...

I think the first computer was invented in 1936 by a German scientist, Konrad Zuse, who later had to flee to Switzerland because of the war... At least that't About.com claims.

You know, it's really funny how things can be invented in several places at the same time... Like the modern guitar as we know it was come up with in China, the Middle East and Spain at the exact same times (and not chronologically, implying that the invention would have traveled)... Or how Pythagores, Zarathustra, Buddha and Lao-Tse, who each pioneered philosophy in their own continent, were contemporaries.

An earlier Difference Engine....

was the one devised by Charles Babbage around 1832. It was started but never completed. However, part of the calculating section was produced in 1832. Babbage revised his design to simplify it but the second version was not produced. The Difference Engine No. 2 was produced from Babbage's plans by the Science Museum in Britain to verify that it would work. The team building it restricted themselves to manufacturing accuracies attainable 150 years ago. It worked after the correction of some small errors, which were felt to be deliberate (the Victorians feared espionage and frequently introduced a few deliberate mistakes into technical drawings.

The printer was completed in 2000. It featured variable spacing and line wrapping. Not bad for something that is 100% mechanical.

It should be noted that as with the machine talked about here, this was a machine for solving simple differential equations (tides) as well as more standard types of maths (i.e., logs, sines and so on) for the production of tables. It was not a general purpose computer, that term was reserved for his Analytical Engine - which was designed but never produced. However Ada Byron, Countess of Lovelace wrote some programs for it, converting equations into algorithms and generating register settings which could be punched on the Jacquard cards (Babbage pinched this idea from the manufacturers of automatic-looms, a long time before Hollerith).

If Babbage had completed the Analytical engine, we could have been in a very different world. One version would have been hypothesized in William Gibson's "The Difference Engine".
