Quantum Theory?

Question

In "Surely You're Joking, Mr. Feynman!" by Richard Feynman. He said that he discovered a phenomenon where an object must make 2 rotations to complete a circle (4 pi). I would like to know some detail about the theory. It's because the discovery later helped feynman in winning the nobel prize

Answer 1

The specific phenomenon is related to antisymmetry in QT. More specifically antisymmetry of spin. Although you should know that the talk of rotations is more of an allegory. Spin is not everyday rotation, it's more a mathematical concept that is closely related to rotation in classical mechanics.
In physics lots of these ideas of higher theories are abstract/mathematical and physicists tend to try to somehow visualize them beyond mathematics. That's why you get some weird stuff like the one mentioned here.

Answer 2

quantum theory is a huge theory, which cannot be adequately explained on yahoo answers. the basic idea is this; all matter/antimatter can be described as particles and waves. Matter waves can be described by Schrodinger's equation. Just as when you are traveling at fast speeds you must use relativity, when you are looking at small objects, you must use QM. This implies that waves, like light, can be considered as small packets of energy (photons) called quanta. The mathematical ramafications of this applies to nuclear physics, particle physics, thermodynamics, cosmology and field theories (among others) you really need to understand advanced calculus and at least intro classical mechanics and EM physics if you want to talk in detail about QM

Answer 3

Watch the movie

What the bleep do we know.

It helps me to understand a lot about the Quantum Theory

Answer 4

I have no idea what it is... it came to me a few times.. and i'm determined to find out.. i hope i'l be able before the hols end.. tell me if you know... mail me at [e-mail]
