Comment Re:"developed an artificial intelligence(AI) progr (Score 1) 152

The only thing the 1950s needed to obtain recent results in convolutional neural networks, was the planar process of 1959 and a suitably accelerated coefficient of Moore's law. We can get there by applying the inverse Hackermann function.

When planning a project, increase the amount of time that you estimate it will take by doubling the number and going up to the next time unit.

Dividing 18 by 2 and shifting to a lower unit gives us a doubling time of nine weeks. Probably we're recognizing cats by 1967. Before the modern API was half fleshed out.

Seriously, have you looked at the sophistication of mathematics in the 1950s?

Ramanujan surprises again

The discovery came when Ono and fellow mathematician Andrew Granville were leafing through Ramanujan's manuscripts, kept at the Wren Library at Trinity College, Cambridge. "We were sitting right next to the librarian's desk, flipping page by page through the Ramanujan box," recalls Ono. "We came across this one page which had on it the two representations of 1729 [as the sum of cubes]. We started laughing immediately." ...

What the equation in Ramanujan's manuscript illustrates is that Ramanujan had found a whole family (in fact an infinite family) of positive whole number triples x, y and z that very nearly, but not quite, satisfy Fermat's famous equation for n=3.

Ono and Trebat-Leder found that Ramanujan had also delved into the theory of elliptic curves. He did not anticipate the path taken by Wiles, but instead discovered an object that is more complicated than elliptic curves. When objects of this kind were rediscovered around forty years later they were adorned with the name of K3 surfaces — in honour of the mathematicians Ernst Kummer, Erich Kahler and Kunihiko Kodaira, and the mountain K2, which is as difficult to climb as K3 surfaces are difficult to handle mathematically.

His work amounts to one box, kept at Trinity College, and three notebooks, kept at the University of Madras. That's not a lot. It's crazy that we are still figuring out what he had in mind. When is it going to end?"

The book is not even closed yet on the mathematics of the 1920s.

Restated as 32% of Americans admit they disagree with American copyright law. Passing laws that most people don't agree with causes the people to stop respecting all laws, leading to them not respecting the government. This is a road that eventually ends with the ruling class dying in a violent revolution.

I ask you this: was less leadership ever required? Has a smaller, easier, less bitterly swallowed step ever been contemplated in the annals of the human condition?

On the "eventually" question, do you think before or after the Second Coming? (Name your sect if you wish, bearing in mind that a diligent and exhaustive land-title-search on "eventually" will set you back a king's ransom.)

In the 18th century, mathematicians such as Euler succeeded in summing some divergent series by stopping at the right moment; they did not much care whether a limit existed, as long as it could be calculated.

Likewise, we are less concerned here with whether history repeats itself in practice, than whether we can by facile bloviation declaim it so.

My point exactly: despite the proverb, it clearly *is* possible to fool enough of the people enough of the time or turds like those would never make it off the drawing board.

You may ask why this is a problem. They can do their thing and I can do mine, right? Wrong. Once 51% make the idiotic choice it's only a matter of time before some beancounter decides that the 49% isn't making enough contribution to the bottom line because Henry Ford or something.

That's nice that they offer the flexibility, but why on earth is the default the one worse for battery life? A non technical user will generally not appreciate the extra resolution while they WOULD appreciate the extra battery life... All users will know is they get an update and the battery life is worse.

This move seems like one that is done by marketing (to make the phones generally look better) than from any group that considers user happiness.
