"Quantum Chromodynamics(theory of quarks and their color)
-Grand Unified Theory(GUTs, as these theories are usually called)
-Relativistic Astrophysics(Black holes and stuff)
-Mesoscopic Physics(VERY INTERESTING AND TIMELY, e.g. small structures, photonic crystals)
-Quantum Information theory(Quantum computers, entangled systems)"
I do know a little about quark colors. It is actually related to something that has nothing to do with actual coloring, just the division of ... I
Well, that helps to explain it. It has to do with quarks and anti-quarks (and gluon I think). That is now part of the standard quantum mechanics, I
The Grand Unified Theory does not yet exist. Every scientist who has tried has failed. Quantum gravity is been the major obstacle so far. Most
other issues have been delt with, but until everything fits together, a GUT cannot exist. It is a hit or miss theory.
Relativistic Astrophysics is just Relativity. Relativity only exists on the macroscopic level, for now, so just saying General Relativity or Special
Relativity or Relativity is ok. This may change soon.
Mesoscopic Physics is something I don't think I've heard of. I do know of photonic crystals, but I never knew of any official branch dedicated to
it. Please post a link if you have anything on this.
Quantum Information Theory is a branch of quantum mechanics that deals with spin of the atoms and marking information as either "existing" or not.
This will greatly help to speed up computers and to solve very difficult problems, but creating a quantum computer is no simple task. My reason for
this is because it seems to involved the Mesoscopic Physics listed above. We have to learn to manipulate light and electrons at a very complex level
in order to achieve a real quantum computer (and quantum computer network).
Thanks for the post.
