The study of heat and how it behaves.

Plank's constant is relevant in quantum mechanics, particularly in the Heisenberg Uncertainty Principal, which says that the uncertainty in position multiplied by the uncertainty in momentum must be equal or greater to 1/2 h-bar, where h-bar is Plank's constant divided by 2 pie.  Another way of saying it is that the uncertainty in energy multiplied by the uncertainty in time must be equal or greater to the same.  Since Plank's constant is already pretty damn small, I'll talk about if it were large enough to affect macroscopic objects directly.  Essentially, all of the laws of physics by which we live our everyday lives would be replaced with quantum mechanical laws.  You could never know where anything is exactly, you could only know it's probability of being at some location.  Large objects would barrier tunnel through other objects, going directly from point A to point B without ever having passed through the space between.  Your position and your energy would have to take discreet values.  For instance, say you were running down a football field.  You might be able to be at the 5 yard line and at the 10 yard line, but you could never be at the 6-9 yard line.  In other words, it would be weird.

The theoretical physics equation E = mc2 states a relationship between energy (E), in whatever form, and mass (m). In this formula, c², the square of the speed of light in vacuum, is the conversion factor required to formally convert from units of mass to units of energy, i.e. the energy per unit mass. In unit specific terms, E (Joules) = M (kilograms) · (299792458 m/s) 2.\n\nMeaning of the Formula:\nThis formula, which was discovered by Albert Einstein, proposes that when a body has a mass (measured at rest), it has a certain (a very large) amount of energy associated with this mass. This is opposed to the Newtonian mechanics, in which a massive body at rest has no kinetic energy, and may or may not have other (relatively small) amounts of internal stored energy (such as chemical or thermal energy), in addition to any potential energy it may have from its position in a field of force. That is why a body's mass, in Einstein's theory, is often called the rest energy of the body. The E of the formula can be seen as the total energy of the body, which is proportional to the mass when the body is at rest.\n\nConversely, a single photon travelling in empty space cannot be considered to have an effective mass, m, according to the above equation. The reason is that such a photon cannot be measured in any way to be at "rest" and the formula above applies only to single particles when they are at rest. Photons are generally considered to be "massless," (i.e., they have no rest mass or invariant mass) even though they have varying amounts of energy.\n\nThis formula also gives the quantitative relation of the quantity of mass lost from a resting body or an initially resting system, when energy is removed from it, such as in a chemical or a nuclear reaction where heat and light are removed. Then this E could be seen as the energy released or removed, correponding with a certain amount of mass m which is lost, and which corresponds with the removed heat or light. In those cases, the energy released and removed is equal in quantity to the mass lost, times the speed of light squared. Similarly, when energy of any kind is added to a resting body, the increase in the resting mass of the body will be the energy added, divided by the speed of light squared.

You are quite curious. What about studying physics? For a "good explicit derivation of this constant" one would have to write a book. The constant derives from the most abstract formulation of mechanics.\n\nskim through this:\n\nhttp://en.wikipedia.org/wiki/Action_(physics)\n\nand attend to the sentence:\n\n"The action is a scalar (a number) with the unit of measure for Action as Energy × Time"\n\nyou can think of 'Planck's Constant' (aka 'plancksches Wirkungsquantum' <-> 'Planck's Action Quantum') as the smallest Action an object can do. If you want to put energy somewhere else you have to take at least ε = h/t (action per time slice).\n\nPlanck introduced his constant to rectify the failure to describe 'blackbody radiation' properly. This failure of his predecessors (Wien, Rayleigh, Jeans) is known as the 'ultraviolet catastrophe'.\n\nhttp://en.wikipedia.org/wiki/Rayleigh-Jeans_law\nhttp://en.wikipedia.org/wiki/Black_body\n\nTo avoid the energy divergence of the blackbody radiation field, he restricted the energy E of each wave of frequency ν to a multiple n = 1, 2, 3, ... of an elementary energy quantum ε = hν. Thus E(ν) = n hν.\n\n\nAt this point quantum theory was born.

I know Einstein came up with it and it deals with energy.\n\nEnergy(E) = Mass(m) * Speed of Light(c2)

The energy of a photon is proportional to its frequency, the constant of proportionality being called Planck's constant who discovered this relation.\n\nE = h * Frequency\n\nIf you know the frequency (or wavelength) of the light you can calculate the corresponding energy.\n\nWhen an electron jumps from an excited state back to its ground state it will emit energy.  If the frequency is in the right range we will see that as light.

He discovered that atoms are not indivisible and are actually made up of smaller particles, electrons. When he first discovered electrons, he formed three hypotheses:\n\n1. Cathode rays are charged particles (which he called "corpuscles"). \n2. These corpuscles are constituents of the atom. \n3. These corpuscles are the only constituents of the atom. \n\nThere were minor changes made to his first and second hypotheses, but the third was completely wrong.\n\nNOTE: The table of contents to the first link is on the bottom left of the page.

This is one of the questions that spurred the early development of quantum mechanics.  \n\nAccording to classical mechanics and Maxwell's electromagnetics, electrons give off light as they rotate in their orbits.  However, in doing so, they would lose energy (the energy keeping them in orbit), and, as you said, would collapse inward.  Another implication of this would be that light would have continuous values of energy as it rotated around and inward.  \n\nPlanck discovered that the energy of light could only have discrete, or integer, values, though he was confounded as to why.  Einstein figured out that light was a particle, a photon, with energy n.  \n\nSorry to drag the answer out, but I find the story behind the story just as interesting and also it was this realization that resulted in the discovery that electrons give off light as they jumped from (discrete) orbit to (discrete) orbit.  Though the means of jumping from orbit to orbit were unknown, it became clear, that by travelling in this fashion, electrons would not lose energy as they rotated, and their orbit would be preserved, maintained by centripital force much like a bucket swung around on a string.\n\nSo, long story short, as mentioned in a previous answer, just as the earth travels around the sun and is preserved in its orbit by its own inertia (which would cause it to fly outward away from the sun) countered by gravity from the sun (pulling it inward), electrons' inertia is countered by the magnetic force of the protons pulling inward.  The key, however, is that the electrons do not lose energy and collapse as they give off light.

The Conservation of Energy!\n\nHere's an easy analogy to follow presented by the famous RICHARD P. FEYNMAN...\n\nSince it is an abstract idea, we shall illustrate the meaning of it by an analogy.\nImagine a child, perhaps "Dennis the Menace," who has blocks which are absolutely indestructible, and cannot be divided into pieces. Each is the same as the other. Let us suppose that he has 28 blocks. His mother puts him with his 28 blocks into a room at the beginning of the day. At the end of the day, being curious, she counts the blocks very carefully and discovers a phenomenal law--no matter what he does with the blocks, there are always 28 remaining! This continues for a number of days, until one day there are only 27 blocks, but a little investigation shows that there is one under the rug--she must look everywhere to be sure that the number of blocks has not changed. One day, however, the number appears to change-- there are only 26 blocks. Careful investigation indicates that the window was open, and upon looking outside, the other two blocks are found. Another day, careful count indicates that there are 30 blocks! This causes considerable consternation, until it is realized that Bruce came to visit, bringing his blocks with him, and he left a few at Dennis’ house. . . .What is the analogy of this to conservation of energy? The most remarkable aspect that must be abstracted from this picture is that there are no blocks.. . . .It is important to realize that in physics today, we have no knowledge of what energy is.

Quantum Theory, also quantum mechanics, in physics, a theory based on using the concept of the quantum unit to describe the dynamic properties of subatomic particles and the interactions of matter and radiation. The foundation was laid by the German physicist Max Planck, who postulated in 1900 that energy can be emitted or absorbed by matter only in small, discrete units called quanta. Also fundamental to the development of quantum mechanics was the uncertainty principle, formulated by the German physicist Werner Heisenberg in 1927, which states that the position and momentum of a subatomic particle cannot be specified simultaneously.

The energy contained is indeed a function of it's frequency and Einstein actually won a Nobel for his work on the photoelectric effect which is  a result of that relationship. The lower the frequency, the longer the wavelength, the lower the energy in the wave. There is no relationship between the speed of light and it's energy content. The speed is determined by two electromagnetic physical constants. Similarly, the speed of sound doesn't depend of the frequency of the sound wave.

Its the frequency/wavelength.\n\nThe "energy" of an EM wave is in its photons.  Each photon\nhas energy of hf, where h is Plank's constant and f is the freq.\nSince Xrays are higher freq than microwaves or light waves, they\ncarry more energy.
