By the time Dr. Nash emerged from his disturbed state, his ideas had influenced economics, foreign affairs, politics, biology — virtually every sphere of life

I would think that his disturbed state actually influenced his theories. I believe that his paranoid schizophrenia started somewhat early on. I cannot imagine how such a profound mental disturbance would not influence one's intellect.

When Barack Hussein Obama won the Nobel Peace Prize for doing ... oh yeah, absolutely nothing, the entire credibility of all Nobel prizes took a swift kick in the gonads. Including those based on science and mathematics.

It wasn't for nothing. It was very likely because at the time he was single-handedly pushing for nuclear disarmament negotiations with Russia. I know this because a relative of mine was involved in the process.

Here is a typesetting comparison between Word and LaTeX. Here is some more discussion. Really, I think LaTeX was created by people who are passionate about the 2000 year old art of typography (Roman). For a long time, MS has ignored far too much of that history in the way it typesets. In my experience, I can always tell a Word document from a LaTeX document, even if the fonts are substantially identical. There is something sub-consciously beautiful about proper typesetting.

What do you mean "in the future"? I've got students whipping out graphing calculators to multiply 2*2.

True story: A math teacher I know once had a student come up to him who claimed his calculator was broken. The teacher took the calculator and entered 4, hit square root and got 2. Entered 25, hit square root and got 5. "Hmmmmm...it seems to work for me" he said. The student then proceeded to take the calculator, enter the number 1, and hit square root repeatedly. "See...the button doesn't work".

Try to do calculus problems without pen and paper. Would Microsoft suggest using MS Word Equation Editor?! Just give me a minute while I swallow my vomit. Ok, I'm fine now.

I'm a LaTeX aficionado. I do quite a reasonable amount of math type-setting. I use LaTeX because the output looks amazing, and because I can use my keyboard alone, instead of having to click on menus and buttons. However, it is still an order of magnitude slower than good old fashioned hand-written problem solving.

+ - New Chips Could Bring Deep Learning Algorithms to Your Smartphone

catchblue22 writes: At the Embedded Vision Summit on Tuesday, a company called Synopsys, showed off a new image-processor core tailored for deep learning. It is expected to be added to chips that power smartphones, cameras, and cars.

Synopsys showed a demo in which the new design recognized speed-limit signs in footage from a car. The company also presented results from using the chip to run a deep-learning network trained to recognize faces. A spokesperson said that it didn’t hit the accuracy levels of the best research results, which have been achieved on powerful computers, but it came pretty close. “For applications like video surveillance it performs very well,” he said. Being able to use deep learning on mobile chips will be vital to helping robots navigate and interact with the world, he said, and to efforts to develop autonomous cars.

+ - Baidu's Artificial-Intelligence Supercomputer Beats Google at Image Recognition 1

Submitted by catchblue22
catchblue22 writes: Chinese search giant Baidu says it has invented a powerful supercomputer that brings new muscle to an artificial-intelligence technique giving software more power to understand speech, images, and written language.

The new computer, called Minwa and located in Beijing, has 72 powerful processors and 144 graphics processors, known as GPUs. Late Monday, Baidu released a paper claiming that the computer had been used to train machine-learning software that set a new record for recognizing images, beating a previous mark set by Google.

Call me a cynic, but the only word I see there is "if".

Yeah well, you probably would have been cynical of SpaceX when their first three launches failed. Now they are on track to dominate the entire industry, even without reusability. Looking at Musk's history, when he says something is possible, you can be quite sure that success is in the set of possible outcomes.

I mean, who's SpaceX's biggest customer? The US Government.

They are the world's cheapest launch service provider and that is without re-usability. They will likely become the dominant launch provider in the world. If they get re-usability to work economically, this will enable mass launches of inexpensive satellites, which could change the entire communications industry. Musk doesn't think small.

I suppose its not a bad thing to have just in case but I don't see the reasoning behind the fixation on it as a design requirement and their ranting about its "importance" in press releases. In almost 300 manned space launches a Launch Escape system has only been of verifiable use in a single incident(Soyuz T-10-1).

The same rockets used for the launch escape will also be used as a propulsive landing system that can land like a helicopter.

The trouble with doing something right the first time is that nobody appreciates how difficult it was.
