Question

what is quantum physics?

Answer 1

, quantum physics is entirely based on the relationship between the wavefunction and the observable operators. Fortunately, the wavefunction itself is deterministic. If you know the wavefunction at any point in time, you can calculate what the wavefunction will be at any point in the future. Thus, despite the apparent randomness of the numerical quantities that we associate with observables, the probability of obtaining a particular number from a measurement can be predicted with great accuracy. This is the focus of modern physics

Answer 2

quantum physics is a branch of physics which deals with physical phenomena at nanoscopic scales where the action is on the order of the plank constant.!
