AI overview
A boson is one of two fundamental types of subatomic particles that make up all matter and forces in the universe, with the other type being fermions. Bosons matter because understanding them is essential to physics, as every subatomic particle must be classified as either a boson or a fermion.

In particle physics, a boson ( ) is a subatomic particle whose spin quantum number has an integer value (0, 1, 2, ...). The class of bosons is one of the two fundamental classes of subatomic particle, the other being fermions, which have half odd-integer spin (1/2, 3/2, 5/2, ...). Every observed subatomic particle is either a boson or a fermion. Paul Dirac coined the term boson to classify the fundamental particles that obey Bose–Einstein statistics, the quantum framework pioneered by Satyendra Nath Bose.
