Einstein started it with his seminal work on the photo electric effect in 1905, where he defined the electromagnetic interaction of certain frequencies on matter. He noted that some frequencies of light would kick electrons out of metals, while most would not. He came to call this effect the "quanta" of the photoelectric effect. He also found that this process was reversible insofar as when the electron connected back to the atom where it had been ejected, a photon, a quanta of electromagnetic radiation of exactly the same frequency as that which kicked it out, was emitted instead. On this discovery and commentary was built all the sum of following quantum theory that describes all atomic and sub atomic processes as discrete phenomenon called quanta, hence quantum theory. It took a few years for physicists to catch up and the first person to approach him was Max Planck who had ideas of quantum mechanics of his own and found the proof he needed in the Photoelectric effect.
Einstein would end up arguing against quantum mechanics and aspects of it that he called "spooky action at a distance". But the findings of quantum mechanics are by and large confirmed. The problem now is to unite general relativity (GR) with quantum theory and so far, no one has successfully done this. Quantum theory has become complex, even unwieldy, but it accurately describes conditions at the atomic and sub atomic levels of reality.
Planck's Quantum Theory of radiation:
According to this theory,radiant energy is emitted or absorbed not continuously but discontinuously in the form of quanta.Each quanta is associated with definite amount of energy.
The energy (E)associated with each quantum foot is a particular radiation of frequency 'v' is given by E=hv where h is planck's constant.
In the case of light,the quantum of energy is called photon.
A body can emit or absorb either one quantum of energy or some whole number multiple of it i.e,hv,2hv,3hv etc called as quantisation of energy.

on the religion forum I was describing what I thought was quantum physics...that the universe is accelerating and expanding in a spiral. Is that quantum or something else or combination of things...?

Does cause really cause the effect, or does the effect create the cause? Is time truly relevant, or do humans simply bash their heads from the questions of life that are truly over our heads theoretically speaking.

Does anyone believe in Quantum Theory?I think it is so interesting when I was reading and talking about it with some people. If you had to explain what it means in a simple basic answer what would you say?

To say I read all of Mr. Campbell's works would be inaccurate, but I have consumed multiple texts that bear his name; even one that includes Bill Moyer. Soon after I followed-up with DVDs and VCRs that demonstrated his...

vote---what do YOU believe in more, big bang theroies being correct or quantum mechanics rules?? einstein on bohr??

A scientific theory must be able to make predictions.Quantum mechanics by it's very nature and laws cannot make predictions. Therefore, can quantum mechanics be considered science?Or is it just experimental metaphysics?
