What does bosonic mean?
"Bosonic" is a technical adjective from particle physics meaning of or relating to bosons — the family of subatomic particles, such as photons, gluons, and the Higgs boson, whose behavior is governed by Bose–Einstein statistics. Unlike fermionic particles such as electrons, bosonic particles carry integer spin and face no restriction against occupying the same quantum state, which is why laser light and Bose–Einstein condensates behave as they do. The term appears chiefly in research papers, textbooks, and serious science journalism: one speaks of a bosonic field, bosonic atoms, or bosonic string theory. It is not used figuratively or informally, and outside scientific contexts it is essentially unknown. The word derives from the name of Indian physicist Satyendra Nath Bose, whose 1920s work with Albert Einstein laid the statistical foundation for describing these particles. For anyone reading modern physics writing, "bosonic" is indispensable shorthand for half of the material world's fundamental constituents.
adjectiveRelating to or characteristic of bosons, the class of subatomic particles that obey Bose–Einstein statistics and include photons, gluons, and the Higgs boson.
- Of or relating to bosons or Bose–Einstein statistics in physics.
"Photons are bosonic particles, so any number of them can occupy the same quantum state."
"In bosonic string theory, the strings vibrate in ways consistent with integer-spin particles."
"Condensation occurs when a large fraction of bosonic atoms collapse into the lowest quantum state at temperatures near absolute zero."
Name a particle after an Indian physicist who never won the Nobel Prize — and physicists will use his name every single day: every photon in the universe is 'bosonic.'

Etymology of bosonic
The adjective "bosonic" is formed from "boson," the particle named after Indian physicist Satyendra Nath Bose, who developed the statistics underlying their behavior in collaboration with Albert Einstein in the mid-1920s. The suffix "-ic" simply marks it as an adjective, following the standard pattern of English scientific coinage. Its closest relative is "boson" itself; the contrasting adjective "fermionic," formed analogously from "fermion" (after Enrico Fermi), was coined around the same period to describe the other great class of particles.
How bosonic is actually used
Strictly technical vocabulary, used almost exclusively in physics literature and advanced science writing; rare in everyday speech.
Easily confused with bosonic
Fermionic describes particles like electrons and quarks that obey Fermi–Dirac statistics and obey the Pauli exclusion principle, whereas bosonic describes particles with integer spin that can share quantum states.
