HOW QUANTUM MECHANIC is started.

 Until 1600's physicists developed classical mechanics. Classical mechanics make sure cause and effect and do not include something by accident. But classical mechanics can't explain situation when velocity of person is same to light's velocity. also it can't explain small world too, like an atom. 
 Quantum in Latin means 'how much'. Plank, Einstein, Heisenberg, Boer showed quantum mechanics. quantum mechanics is about probability. it is like throwing coins. I throw coin and it is the front of the coin. but I don't know the next time I coud get front of the coin. A key part of quantum theory is that we don't know certain states of particles, (position, speed, direction it moves in, and spin) until they are observed. 
 Quantum mechanics led to the location of electron in orbit. It shows that a light could be described by a particle, a small basic thing. Quantum mechanics is used for lasers, MRIS, Electronics, and Spectroscopy.
