With Congress and the Senate in the hands of the republicans, what can he really do? Pretty much nothing except twiddle dials.

I'm not lying, though I'm not giving up my pseudo-anonymity. He was involved in the International Commission on Nuclear Non-proliferation and Disarmament.

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.

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.

Nor division.

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.

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.

The problems at Roscosmos couldn't have anything to do with financial irregularities and misuse of funds, or financial pressures caused by the current economic crisis. Nope. Nothing to see here. Move along.

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.
