Quantum Mechanics is both very intriguing and very confusing. First, I must answer the most commonly asked question about quantum mechanics, what is it? Quantum mechanics is the study of the radioactivity and physics of atoms. Another question you may have is why classical mechanics will not apply to atoms. This answer is simple, classical mechanics is imperfect. Quantum mechanics apply to all matter, and so does classical mechanics except for on an atomic level, so the much easier classical mechanics are still used for larger matter even though they are altogether incorrect. There are many things that quantum mechanics can explain that classical mechanics cannot. The first of these is that light acts as both a wave and a light. Quantum mechanics explains that light actually exists as a particle, but the probability of the position of the photon is
The location of a particle is not definite. The idea behind quantum mechanics is to use calculations to discover the possible locations of these particles. One interesting probability that comes out of this is the probability of quantum tunneling. Quantum tunneling is when an energy wave hits an energy barrier, and most of the wave is reflected back, but some of the matter may tunnel through the energy barrier. This is also theoretically possible on a larger scale, for example, if you were to drop a penny on your hand, there is a very small chance that it could fall straight through your hand and leave it undamaged. Quantum mechanics have helped society in an enormous way. Without the discovery of quantum tunneling it would be impossible to have computer chips and computers would be enormous. This is only an introduction to the confusing world of qu
