Did you know ? Quantum mechanics is a theory that deals with the behavior of subatomic particles such as atoms and their constituents. Quantum mechanics describes how particles behave at microscopic levels, such as their motion, spin, charge, energy, and various properties. This theory is important for understanding many physical and chemical phenomena, such as the electronic structure of atoms, spectroscopy, electron microscopes, nuclear reactions, and many others. Quantum mechanics is also important in many modern technologies, such as quantum computers and cryptography.
