Physics
In physics, the concept of charge is derived from the observation of conserved quantum numbers.
Various charge-like quantum numbers have been introduced by theories of particle physics, e.g.
- electric charge for electromagnetic interaction,
- magnetic charge (currently purely theoretic),
- colour charge for gluons,
- quark charges like strangeness, and
- isospin for electroweak interactions.
In the formalism of particle theories charge-like quantum numbers can sometimes be inverted by means of a charge conjugation operator called C. Chiral fermions often cannot.
