DANCING QUANTUM PARTICLES

✍AstroMuon Kuki🚀

All the known particles in the universe can be divided into two groups: The ones that have an integer spin 0 , 1 , 2 that form all the matter in the universe (these are known as bosons) and the ones which have a 1/2 integer spin which give rise to the forces (fermions) acting upon matter particles. Common examples of bosons are photons, gravitons, He4 atoms, etc. Common examples of fermions are protons, neutrons, and electrons.

And in the most simple words, Pauli’s exclusion principle says that two identical fermions cannot be in the same quantum state. (viz., the condition of its quantum mechanics system which can be described through a wave function or a complete set of quantum numbers)

The Pauli exclusion principle is said to be one of the most important principles in quantum physics, largely because the three types of particles from which ordinary matter is made (electrons, protons and neutrons) are all subject to it, so that all material particles exhibit space-occupying behavior. Interestingly, though, the principle is not enforced by any physical force understood by mainstream science. When an electron enters an ion, it somehow mysteriously seems to "know" the quantum numbers of the electrons which are already there, and therefore which atomic orbitals it may enter, and which it may not.

Thus, it forms the base of many quantum concepts, understanding which will enhance your understanding of the principle itself.
