About Quantum mechanics

Wave functions of the electron in a hydrogen atom at different energy levels.
Quantum mechanics is a fundamental theory in physics that provides a description of the physical properties of nature at the scale of atoms and subatomic particles. It is the foundation of all quantum physics including quantum chemistry, quantum field theory, quantum technology, and quantum information science. Quantum mechanics cannot predict the exact location of a particle in space, only the probability of finding it at different locations.
