As many pointed out, internal energy of the quantum system can't be less then some zero-level > 0. On the other hand, temperature is statistical property and if we extend it to non-equilibrium systems, it is possible to have inverse population of energy levels, which resilts in negative velue for temperature.

Why is it modded funny? This is how it supposed to be. But I might prefer even little higher temperatures and some rest after snow or ice water

1) And after that you call a guy sitting in WTC and designing a military drone with AI "an innocent civilian". Taliban figther sure doesn't see it that way.
2) Old eye for eye comment: you can flatten all 2+ store buildings, set puppet goverment and do manhunt, but what do you do with with a guy who lost the last reason to live (a child, wife, loved one) due to american bomb? Or due to the american-supported tribe from the north? Well, the right solution is to kill them all, of course.
3) For some reason, an opinion of US citizen which has a military drone at his/her service have a lof bigger weigth than an opininon of an average human from planet Earth. Somehow people don't like this.
4) When this technology will be mature enough, one guy (or dozen) can "go crazy" and decide that they do not want democracy in the US anymore. It will be very difficult to object to this having laser beam on your back. Technological advance for people service, right!

Yeah, US doesn't torture prisoners, it just asks right folks from North Alliance to get the information. Very easy.
Playing Civ III, I came up with idea that "democratic" nation should keep its people happy, produce all goods and give them to "despotic" nation which will do all dirty work. If it is so obvious even in the game, imagine how elaborated it can become in the real world!
I was always wondering why they do not average time for spec number (harmonic average for scores). That way it would be very difficult to change average with only 1 test. Yes, they do something like this for spec_rate, but this test is mainly for multiprocessor systems
I think actors and music in Shrek were brilliant, but I hate the idea they put in this movie - you can be ugly ogre and still be beautiful. Why bother and try to improve yourself? You just need to wait for equally ugly wife and produce ugly children happily thereafter. And they (and I) don't mean physical beauty only...
Fast ethernet is good enough for pretty big range of well-written parallel applications. In general, the ratio of CPU power/communication has to be proportional to nonlinearity/nonlocality ratio of the problem the computer is designed for. Usually, for partial differential equations, explicit timestepping algorithms put little strain on communications. OTOH, once you go to implicit transport equations of any kind, you need all communications you can get.
And, memory bandwidth is a bitch, I agree. Those dual athlons really have memory bottleneck:(
>Do we need high-order simulation of planetary orbits in a space shooter?
It depends. If you want to stay on the same orbit after 10 loops - yes, you need all accuracy you can get. If you have a crazy gamer who presses keys every millisecond - no, right parts of equations will have bigger effects than any integration errors you can have. Sometimes high-order schemes can produce worse results.
>Not quite sure how to take your comment on my degree
Sorry being nasty. But you need better feeling what is the right method for a problem.
Where is the world going? The orbit simulation is probably the most complex problem for integration ordinary differential equations. 3-(or more)-body problem does not have closed form solution and can have attractors with fractal dimenstions. This kind of problems are very difficult to integrate numerically. 16-th and higher order methods (opposed to usual 4-th order runge-kutta) are most common. On the other hand, "simulating heat flow within in a heatsink" is usually done with no more than 4-th order schemes and 2-nd order are most common. (Partial differrential equations have other problems, of course)
Guess what: quantum mechanics is also approximation in nonrelativistic limit. Only 1 electron (Dirac) problem was solved so far without any approximation (with latest model of universe)

Another possibility would be to define god(s) as having some "irrational" constituents, which ALWAYS will violate laws of nature and logic.
