You mean, assume we take a bunch of charged particles with relativistic speeds and see what happens when they interact? That's what physicists do using accelerators. (Except they don't really observe the positions of particles at all times

Well, it isn't, and no, I haven't confused General with Special Relativity, trust me on that :) Maybe you confused Quantum Mechanics with Quantum Field Theory?

When a physicist studies Qunatum Mechanics, he knows that on the macroscopic scale, QM will behave like classical electromagnetism. Why do you say this? Quantum Mechanics in the classical limit does not become classical electrodynamics.

by pfedor 17y ago
You say "the problem cannot be solved in classical electrodynamics". Firstly, I'm not sure I agree. I would be happy to be proven wrong, but that's what I remember from studying physics many years ago. You can calculate the motion of a c

So for starters, if by "macroscopic" you mean a object that has a finite size (as opposed to point objects), then the problem is underspecified, because you didn't give a model of the finite size objects' behavior under the action of extern

Highschool is a mechanism to socialize you and a filter for colleges. That's what they kept telling me. I don't believe it. I for one acquired little social skills in high school and orders of magnitude more since I started working. I t

Can one drive it on a freeway? The article doesn't really say that, although the comparison to Honda Civic suggests that the answer is yes.

Let me use this opportunity to make a plug for another excellent writer. If you like Greg Egan, chances are you will like Stanisław Lem, who tackled some of the very similar questions in his work. One good place to start is: http://www.a

OK so let's take out one cell of your brain and build two identical electronic braincell replacements (if braincells need randomness, let's say they're both connected to the same source of randomness, or use they same pseudo-random algorith

In downtown Palo Alto you can see people sitting on the sidewalk with cardboards which say they lost their jobs and don't have money for food, talking on their iPhones.

I'm surprised by the direction this conversation is taking. I assumed the confusion came from a misunderstanding of what MapReduce was, since it's a much less known technology. My comment was intended to clarify this confusion. I didn't

You can write a paper comparing Perl with MySQL, and if you put enough effort into it you may even conclude that MySQL has better performance, but this doesn't make the comparison any more meaningful.

by pfedor 18y ago
You are absolutely correct. MapReduce is chiefly a framework for performing distributed computation. RDBMSes, colloquially referred to as "SQL databases", are for data storage and (parallel, transactional, ...) access. If you want to com

I'm guessing that among people who make, say, $100k+ a year, 95%+ finished college. So it's somewhat interesting that the trend reverses for larger values.

You can install Linux on a Mac these days too.

by pfedor 18y ago
I agree with everything you said but I would take it even further. One doesn't even have to go to chemistry or finance to find better things to invest time in than learning new tools. There are plenty of areas within the domain of compute

I wonder what "normal immigration process" you have in mind. Marrying a US citizen?

True. I knew people who were born in Switzerland and lived in Switzerland their whole lives, and still had Spanish passports only.

I would also mention Switzerland. I met plenty of people in Google's Zurich office who didn't get an American visa or were waiting for an American visa. For an engineer who has a job offer, getting a work permit in Switzerland is a few da

Interpretation of quantum mechanics is outside of the scope of physics, it's more like philosophy or something. For physics to be like economy in that respect, there would have to exist, for example, university professors who still wouldn'

A friend of mine who's a physicist claims that he's so used to Mathematica that he uses it for everyday scripting tasks, the way other people use Tcl or Perl.
