**theory**of the atom,**quantum**mechanics is perhaps the most successful**theory**in the history of science. It enables physicists, chemists, and technicians to calculate and predict the outcome of a vast number of experiments and to create new and advanced technology based on the insight into the behavior of atomic objects.**Einstein's**equivalence principle, on which general**relativity**is founded, requires that in any local, freely falling reference frame, the speed of light is always the same. [1] [2] This leaves open the possibility, however, that an inertial observer inferring the apparent speed of light in a distant region might calculate a different value.This is one big book, and it takes time to look through topics as diverse as general

You get a Ph.D., join a faculty, they show you your office, and then tell you “By the way, you’re teaching 205 next semester.
