Microcosmology : Atom light-second/light-year : The distance travelled by light in one second/year. magnetic field : The field responsible for magnetic forces, now incorporated, along with the electric field, into the electromagnetic field.
mass : The quantity of matter in a body; its inertia, or resistance to acceleration. microcosmology: see, cosmology. neutrino : An extremely light (possibly massless) elementary particle that is affected only by the weak force and gravity. (page 37). neutron : An uncharged particle, otherwise very similar to the proton, which accounts for roughly half the particles in the nucleus of most atoms (page 21). neutron star : A cold star, supported by the exclusion principle repulsion between neutrons (page 64). nuclear fusion : The process in which two nuclei collide and coalesce to form a single, heavier nucleus (page 54). nucleus : The central part of an atom, consisting only of protons and neutrons, held together by the strong force. particle accelerator : a machine that, using electromagets, can accelerate moving charged particles, giving them more energy. phase : For a wave, the position in its cycle at a specified time : a measure of whether it is at a crest, a trough, or at some point between. photon : A quantum of light. Planck's quantum principle : The idea that light (or any other classical waves) can be emitted or absorbed only in discrete quanta, whose energy is proportional to their frequency (page 23). positron : The (positively charged) antiparticle of the electron. primordial black hole : a black hole created in the very early universe (page 64). proton : The positively charged particles that make up roughly half the particles in the nucleus of must atoms.
