Could someone explain me about Quantum Chromodynamics?

QCD is a theory of the strong force.  Particles have a color charge.  For QCD you have three different colors of quarks (usually called red, green, blue).\n\nAnother major difference in QCD is that the force carrying particle, the gluon, is charged.  In electromagnetism, the photon is the carrying particle, and it is neutral.  There are actually 8 gluons (red - antigreen, red - antiblue, green - antired, green - antiblue, blue - antired, blue - antigreen, and then two different gluons that are combination of red - antired, blue - antiblue, and green - antigreen).\n\nBecause the force carrying particle is charged, it makes the theory very difficult mathematically to solve.  In fact, it has not yet been solved.  Even with the difficulties, there are lots of good approximations and many predictions can be made with it.

It sounds like you are talking about an area of science known as quantum mechanics, though you might be referencing subatomic particle theory.  Yes, the math can be a bit much and the conceptualizations a bit forced.  But not knowing you I am hestitant to say no way.  Maybe you could should start out with little thermodynamics.\n\nThe first site below is one called HyperPhysics.  The link will send you straight to the grid on thermodynmics.  Try tapping the buttons, read and little and see if it makes sense.  I suggest you start with kinetics.  If HyperPhysics doesn't do it for you, try Wikipedia.  If you want to leap in head first the last reference is about string theory, tachyons and all that good stuff.  Good luck and heppy learning.

Tiny particles called gluons.

Yes! in the Sub Atomic particle. Photons behave the same way.

A good website on quantum mechanics: http://en.wikipedia.org/wiki/Quantum_mechanics\n\nAlso, if you are intrigued by the cosmological theory of the universe, The Life of the Cosmos by Lee Smolin is an excellent read.

Feynman diagrams are a way to graphically portray sub-atomic particle interaction. You have to understand the underlying principles before you can understand the diagram. They can't be explained in a few words. Look them up.

Hi vacanucks\n\nA fock space is a mathematical space for the action of QM operators.  If you're familiar with operators acting in hilbert spaces, this is like "mutlidimensional" hilbert space - it's the addition of n=0 particle hilbert space (vacuum state), n=1 particle state, n=2, n=3...\n\nI can't think of a physical interpretation for it - I doubt there is one.\n\nHope this helps!\nThe Chicken

You can use the Rydberg formula, which relates the reciprocal of the wavelength of the photon absorbed or emitted to the squares of the reciprocals of the principal quantum numbers.\n\n1/wavelength = R(1/n_l^2 - 1/n_u^2)\n\nSo, for the listed values of n, \n\nA.  1/w = R(1/ 2^2 - 1/4^2) = 0.1875R\nB.  1/w = -0.75R\nC.  1/w = 0.21R\nD.  1/w = -0.04861R\n\nSince energy and frequency are proportional to 1/wavelength,\nlooks like the order is D, A, C, B.

Feynman diagrams are used to compute various quantities in an area called quantum field theory. Quantum field theory is an application of quantum mechanics to collections of particles and fields (like electromagnetic fields for example). For example, one might want to compute a "cross section", that is, the chance that a certain type of particle will be found at a certain place in an experiment where the particles are bouncing off a target. \n\nInstead of solving the probabilities using the partial differential equation known as Schrodinger's equation, Feynman formulated the problem as an integral equation (that is, instead of describing the probabilities in terms of an equation for how they change, an equation involving the sums of probabilities was produced instead). However, the integral equation cannot be solved directly, but instead is solved as a infinite series, or sum of terms. Each term in this series can be thought of as a certain kind of interaction by the particles in the system. Each of these terms in the series is represented by a Feynman diagram. A Feynman diagram is a pictorial characterization of this interaction. Feyman diagrams give an intuitive way to think about the ways these particles associate with each other and effect each other, and also make extremely challenging computations much more tractable. Each term is produced, then evaluated and summed to some desired level of accuracy. \n\nThis is only gives a very vague sketch of the basics of Feynman diagrams, but hopefully they will give you some idea about what they are good for and how they are used.

hmmm... \n\nWell the book that got me turned on to physics was "The source book on atomic energy"\n\nThis book starts off at newton and goes up to the nuclear reactors and basicly every thing that was known about nuclear technoolgy at the time (the book is about 50 years old).  It is not quantum mechanics, but it is modern physics.  And modern physics is the start to quantum.  It will give you ALL the backround that you need to know to start to really learn quantum. Also it is very easy to read (I read it the summer after my freshman year in college)  \n\nanother serise of book (also not quite to hard quantum yet) are the "Mr Tompkins" series.  he describes things like the atom and relitivity very well and in a hands on approch.  \n\n\nNow for quantum... I did read one decent book, but i can not remeber what it was.  Just go to your local library and do a search for quantum mechanics and pick up the shortest paper back you can find.  they are all written by very smart people and they are writen so that every on can under stand them.  \n\nI am sorry I did not help to much with a Quantum book, but the other two books that I recomended are very good and will put you directely on the right path towards understanding modern physics,  and you can not understand quantum with out understanding modern (actualy there is usualy a bit of quantum is modern physics classes)

Is this row-echelon form of diagonal? Dirac, Heisenberg matrix? Isn't -Psi just the unlikely probability of the electron function? Does Psi have anything to do with energy? Could you explain further.

Up: About 4 MeV\nDown: About 8 MeV\n\nThese should be compared to the mass of a proton: 938 MeV. Most of the mass of a proton is the energy of the interaction of the quarks, not the quarks themselves.

Quarks are the basic building blocks of some other sub-atomic particles, like the proton. Quarks, unlike other particles, can not be divided.\n\nQuarks are best on crackers with just a dab of peanut butter.

In order:\n\n1) Red, blue, and green colour charges are distinct, but arbitrary, exactly like + and - electrical charges.  There is a difference between something positively charged and something negatively charged.  With quarks, it's simply that there are three different kinds of charge, instead of just two for electromagnetism.\n2) Because gluons are, themselves, influenced by the strong force, a correct description of the quantum force diagrams (penguin diagrams, if you know that term) must necessarily include higher order interactions than simply quark <-> gluon <-> quark.  The one you propose is, I believe, possible by the rules governing the quantum behaviour of quarks and gluons, as are many, many more distinct diagrams.\n3) There is no meaningful order.  RBG and RGB are both "colourless".\n4) String theory is outside of my area of expertise, I don't think I can address this issue in any meaningful way.
