Force Carrier
In particle physics, forces between particles arise from the exchange of other particles. These force carrier particles are bundles of energy (quanta) of a particular kind of field. There is one kind of field for every species of elementary particle. For instance, there is an electron field whose quanta are electrons, and an electromagnetic field whose quanta are photons. The force carrier particles that mediate the electromagnetic, strong, and weak interactions are called gauge bosons.

Famous quotes containing the words force and/or carrier:
“The ideas of the ruling class are in every epoch the ruling ideas, i.e. the class which is the ruling material force of society, is at the same time its ruling intellectual force.”
—Karl Marx (1818–1883)
“When toddlers are unable to speak about urgent matters, they must resort to crying or screaming. This happens even with adults. The voice is the carrier of emotion, and when speech fails us, we need to cry out in whatever form we can to convey our meaning. Often, what passes for negativism is really the toddler’s desperate effort to make herself understood.”
—Alicia F. Lieberman (20th century)
