"The World's First Computer Start-Up" ... In 1941


Here.

Also Here.

... and, in abstract but I must say thought-provoking ... This.

Enjoy!

Those are indeed fascinating and chronicle the power of manipulating electrons. Of course before that we manipulated larger objects to do similar work as Necessity is the Mother of Invention (with a sideways nod to Frank Zappa) as seen in Pacal's computer, the Pascaline which he invented to assist his father in calculating taxes in 1645 and the Daddy of them all, the Abacus invented in 500 BC. I am curious as to why the base 10 method of using hands common in some Asian countries and amazing to witness wasn't developed sooner.

For anyone unfamiliar with the "mental Abacus' here is an instructional video -- How to Multiply Any Numbers, FAST --

Some may find simple instruction boring but look up videos of kids in South Asia using this method with astonishing speed and accuracy. It is jaw-dropping.

It is interesting that all of Zuse's computer designs, including his first mechanical ones, were binary and supported floating-point arithmetic. Some people have said that Charles Babbage would have met with more manufacturing success had he thought to use a binary system, since the biggest obstacle to his designs was the accurate manufacturing of precision gears and the drag of turning shafts which were linked to one another in gear-chains.

Others have noted that the cryptanalytic uses of these machines were barely mentioned – although Zuse did discuss them – and to express disbelief that, if such ideas were known to the Germans before war broke out, the British didn't also know of them and use them somehow at Bletchley Park. I think that, although much is now revealed of the BP story, there are still a great many classified secrets there.
