Question

Hello,I'm a beginner to physics ,could you tell me how to learn quantum mechanics and what's the meaning of it exactly ?

Answer 1

it is a branch of physics providing a mathematical description of much of the dual particle like and wave like behavior and interactions of energy and matter. It departs from classical mechanics primarily at the atomic and subatomic scales, the so-called quantum realm. In advanced topics of quantum mechanics, some of these behaviors are macroscopic and only emerge at very low or very high energies or temperatures. The name "quantum mechanics", coined by Max Planck, derives from the observation that some physical quantities can change only by discrete amounts, or quanta. For example, the angular momentum of an electron bound to an atom or molecule is quantized. In the context of quantum mechanics, the wave–particle duality of energy and matter and the uncertainty principle provide a unified view of the behavior of photons, electrons and other atomic scale objects

Answer 2

but if you just start n physics you should study classical mechanics and physics 1 first ........ Good luck

Answer 3

feynman lectures on physics vol 3 you can understand the concept easily ,my wishes
