Proton torpedoes skillfully placed (with an assist from the Force) sparked a chain reaction which destroyed the putatively indestructable battle station.
The nucleus of a hydrogen atom is a proton.
Those who take different kinds of medication, notably proton pump inhibitors (like the common over-the-counter acid reflux drug Prilosec) have lower amounts of the stomach acid needed for proper B12 absorption from food.
Ordinary hydrogen has only one proton in the nucleus, while the isotope deuterium has one proton + one neutron.
The experiment is located at the proton electron accelerator HERA at DESY in Hamburg, Germany.
