Assigned to lvl2, but maybe I can talk Saddam into convincing Satan to displace me to lvl1 by telling him I was against the war in Iraq. Homer, Socrates and Aristoteles propose to be better company than Cleopatra (or Helen, whoever that is). Seeing your violence-lvls I´m quite happy that I´m...

A circle can be considered the set of all point that have a certain distance (the radius) from a certain point (the center). In above case the center is the origin (0,0) and the distance is R. Thus, the cirlce is the set of all points (x,y) which have a distance R from the origin. The...

Gauss and Feynman would be my favorites for maths/physics. While the first one is rather obvious (maybe not as THE best mathematical but certainly as a very successful one), Feynman would be there just out of a personal feeling and my respect for the Feynman graphs which brought the description...

Hit the "print" button on your keyboard, go to paint and press Ctrl-V. EDIT: For clearification: That´s how you do a screenshot in Windows. If your Matlab runs in fullscreen or on another OS that probably won´t help you.

Both legs are equal lenght, especially the left one. EDIT: "Both legs are equal lenght, especially the other one" might be an even better answer.

Vectors are invariant under changes of the coordinate system (what you probably mean by tranformation). Only their representation as a linear combination of the base vectors changes (as an inverse to the changes of the base => contravariant vectors). As the vectors (do not confuse a vector with...

I wouldn´t know of any other method than using ASCII or TeX.

I don´t know how to include .jpg, I only know how to include .eps. What I usually do when I have to include a figure is printing it to a file (PostScript printer), then convert it to .eps with Ghostview and then include the .eps-file. Not very elegant and a bit time-consuming but it works.

>> in other words it has divisors other than 1 and X+1 Not if my list of primes I start with is complete which was the assumtpion I started from. However, I realize how and why my post was misleading and/or improperly written. Thanks for showing where the problem lied, I´ve edited the...

All textbooks I know define the Christoffel-Symbols in a way that they are symmetric in the last two indices and in that definition the minus-sign should be at the derivative by x^a (when a is the first index as above). Also I´ve never seen any other convention anywhere else. If your computer...

Bad example as it doesn´t give the n-th prime but the link is interesting, thanks. @StatusX: I don´t really see a problem with my post although I have to admit that I took that out of my head and didn´t bother to look up a more elegant proof somewhere. I will consider rephrasing what I wrote.

It´s actually so simple that I can post it here: (1) Assume a nonempty finite set P of primes. (2) Let X be the product of all these primes. (3) X+1 does not divide by any element in P so P cannot be the set of all primes (as any number except One divides by at least one prime). As this is...

>> However, if v is some element of V, then T(v) = Av, but Av is not even possible, since >> it involves multiplying two square matrices of different dimension. I´m not completely sure if I got your question but maybe I´m guessing right where your problems lie: Assume a linear operator O...

Well, I think the problem is that your view on temperature derives from Classical Thermodynamics. Classical Termodynamics more or less directly compares to the more modern Quantum Statistics as Classical Mechanics compares to Quantum Mechanics - obviously becaue they are based on Classical...

@Chronos: Three questions and one suggestion: q1) Where is the connection between uncertainty and temperature in your post? Uncertainty never appears except at the point where you claim that "it has everything to do with absolute zero". q2) If an atom in it´s energetically lowest state...
