Particle composed of three quarks

Usage examples of proton.

Proton, plus the societies of werewolves, unicorns, vampires, demons and assorted monsters.

But as far back as 1950, hyperons had been discovered, elementary particles bigger than protons and neutrons.

The high-energy proton spectrpmetry clusters flunked out, too, as did the gravimetric distortion mapping scanner, the fixed angle gamma frequency counter, the wide-angle EM radiation imaging scanner, the quark population analysis counter, the Z-range particulate spectrometry sensor, the low-frequency EM flux sensor, the localized subspace field stress sensor, the parametric subspace field stress sensor, the hydrogen-filter subspace flux scanner, the linear calibration subspace flux sensor, the variable band optical imagining cluster, the virtual aperture graviton flux spectrometer, the high-resolution graviton flux spectrometer, the very low energy graviton spin pola-rimeter, the passive imaging gamma interferometry sensor, the low-level imagining sensor, the virtual particle mapping camera, and even the life-form analysis instrument counter.

Anchee Ye and Penn Brown spend a week at the Kennedy Space Center, learning how to use the proton drill rig.

In the first microsecond, space was filled with quagma, a swarming magma of quarks, as if the whole universe was a single huge proton.

Paraetonium to Siwa to here, hundreds of kilometers beyond human thought or action, half a mile down, where the gigantic claw diggers had ceased their abrading, the two of us with simple pick and shovel, standing on the last thin layer of compacted dirt and rock that roofed whatever great shadowy structure lay beneath us, a shadow picked up by the most advanced deep-resonance-response readings, verified on-site by proton free-precession magnetometry and ground-penetrating radar brought in from the Sandia National Laboratory in Albuquerque, New Mexico, in the United States.

Actually, that makes sense: neutrons decaying into protons and pions would transmute some of the calcium to scandium, the oxygen to fluorine, and the carbon to nitrogen.

It was a heavy isotope of hydrogen, with one proton and one neutron, and the Big Bang had made only a pinch of it, before stingily shutting off production just three minutes after creation.

Sam Cottage, monitoring the Sun on the morning after lift-off, saw with interest that Region 419 had maintained its horseshoe configuration, with signs indicating that a sunspot big enough to see with the naked eye might be developing, but there was no indication that a solar proton event might erupt.

ATP synthase molecule as the protons pass through a tunnel and out the other side of the membrane.

She got one in her sights and used a proton torpedo while it still made sense, then needled it with laserfire until the torp got there and blew it into molten slag.

Two twistor combinations produce electrons, three can create protons and neutrons, die building blocks of atomic nuclei.

He soon found that if beryllium was bombarded with alpha particles, a kind of radiation consisting of particles with a mass close to that of the proton were produced.

When protons were bombarded with high-energy electrons, pointlike charges were discovered inside the proton.

The more typical vibrating fundamental string corresponds to a particle whose mass is billions upon billions times greater than that of the proton.
