*Bosons* constitute one of the two main categories of sub-[[Atom|atomic]] particles in physics. "Sub-atomic" means: smaller than an atom, i.e., all atoms are made of sub-atomic particles. Particles of the second main category are called [[Fermion|fermions]]. Bosons have integer [[Spin|spin]], and unlike fermions, they can **all occupy the same quantum state** at once. This “crowding” property is behind phenomena like [[Laser|laser light]] and superfluidity. Examples of bosons include the [[Photon|photon]], the Higgs boson, and gluons (which hold quarks together). >[!read]- Further Reading >[[Fermion]] >[[Bose Einstein Condensation]] >[!ref]- References [News article on the discovery of 'paraparticles', a particle type beyond bosons and fermions](https://www.nature.com/articles/d41586-025-00030-5)
