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

The rules of quantum mechanics assert that the state space of a system is a Hilbert space and that observables of the system are...
Xem thêmSince its inception, the many counter-intuitive aspects and results of quantum mechanics have provoked strong philosophical debates and many interpretations.

Xem thêmQuantum mechanics was developed in the early decades of the 20th century, driven by the need to explain phenomena that, in some cases, had been observed in earlier times. Scientific inquiry into the wave nature of light began in the 17th and 18th centuries, when scientists

Xem thêmQuantum mechanics has had enormous success in explaining many of the features of our universe, with regards to small-scale and discrete quantities and interactions which cannot be explained by classical methods. Quantum mechanics is often the only theory that

These properties suggested a model in which electrons circle the nucleus like planets orbiting a sun. However, it was also known that the atom in this model would be unstable: according to classical th…
