Particle Physics is for jerkoffs.

Indeed, I feel it is, to put it mildly. Why? Because the equations are just too long and tedious; there are just too many assumptions and uncertainities; and the number of elementary particles is just too high (24, are you kidding me?). So, I feel strangely attracted to Quantum Physics, the arch-enemy of Particle Physics. Quantum Mechanics defines the behaivour of things which are so small that they disobey the present laws and coventions of Particle Phy. For example, a car that is only a few millimeters in lenght. It is just too small. The traction will go to hell, and the engine will get nicely screwed up. Overlooking such practical examples, let me elaborate on Q.P. in the way that is considered more, ah, traditional. Q.P. actually tells us about the behaivour of elementary particles inside the atom. Like, it says that electrons do not revolve around the nucleus in definite paths (something P.P. comfortably claims), instead the electrons "float" around the nucleus in the form of electron clouds, and we measure the probability of finding an electron at a particular instant around the nucleus. So much for the basics. Now, what makes Q.P. really interesting is the phenomenon of Quantum Computers, an idea proposed by Richard Feynman in 1982. According to Feynman, a quantum computer is an unimaginably powerful computer that can be made from a single molecule. It utilizes all the 32 states of an electron, unlike a modern day computer that uses only two of them, i.e., 0 and 1. Right now, there are just too many problems and practical issues which come in the way of developing a working prototype of this kind of a computer.

"Nobody understands quantum mechanics." - Feynman

I beg to differ.

A car that small, also, would be very hard to get into, and it would be difficult to fill it with enough fuel to carry it from one fueling station to the next. But think how easy and pleasant it would be to park!

You need some Superstring Theory lovin'…

I love QM. Not the mathematical part of it though, the philosophical part.
There was this movie(15 Park Avenue) discussion that I attended once and I explained the movie's inexplicably weird ending using Schrodinger's equation and the Multiverse theory and recieved a standing ovation for it at the discussion :-)Would tell you about it some day if I get a chance.
