MECHANICS QUANTUM THEORY

What I learned from this concept so far is, every electron has its own energy.The energy is used to 'jump' from its original orbit to another orbit.There is some math calculation involved when the thing happens.Mechanics quantum also can be related to Einsten's Relativity Theory. The difference is, Einstein use a large object to show what is going to happen if the object move on a speed of light while Mechanics Quantum, Neils Bohr latest theory showed that the electron can be replace the object as the moving object .
