017) Lorentz factor
019) The Standard Model of particle physics is the theory describing three of the four known fundamental forces (the electromagnetic, weak, and strong interactions, while omitting gravity) in the universe, as well as classifying all known elementary particles.
020) In particle physics, an elementary particle or fundamental particle is a subatomic particle that is not composed of other particles.
021) In physics, the
Lorentz transformations are a six-parameter family of linear transformations from a coordinate frame in spacetime to another frame that moves at a constant velocity relative to the former. ... The transformations connect the space and time coordinates of an event as measured by an observer in each frame.
