Proton, Captain. Fictional hero of a holodeck program created by Tom Paris. The Adventures of Captain Proton is based on old Earth film serials from the 1930s. Captain Proton is normally accompanied by his trusty sidekick, Buster.
Protons were therefore a candidate to be a fundamental particle, and hence a building block of nitrogen and all other heavier atomic nuclei. In the modern Standard Model of particle physics, protons are hadrons, and like neutrons, the other nucleon (particles present in atomic nuclei), are composed of three quarks. Although protons were originally considered fundamental or elementary particles, they are now known to be composed of three valence quarks: two up quarks of charge +2/3 e and one down quark of charge â1/3 e.
