What is qauntum physics?
Quantum physics is what happens on a very small scale.. If you think about your ipod you have what is called a continuous volume setting... you can set it at any level from 1 to 10 for example and all the decimal places in between. This is known as a continuous spectrum. On a subatomic level, we have a discreet spectrum, so if you had a quantum ipod it would have volume going from 1 to 10,but you could only go up in jumps of 1. This is known as quantisation. This applies to energy in subatomic systems. There are lots of other consequences, but I'd suggest getting a book for that.
