商品簡介
A retired director of the American Institute of Physics, Ford presents his questions in 15 sections on such matters the small and the swift, atoms and nuclei, constancy during change, waves and probability, and quantum physics at every scale. Among the questions are what is Planck's constant and what is its significance, what are some quantum scales of time, why do bosons and fermions have such funny names, what are the big four absolute conservation laws, what is the two-slit experiment and why is it important, how do electrons behave in a metal, what is superconductivity, and what is string theory. A high-school or undergraduate background in physics makes following his explanations quicker. Annotation c2011 Book News, Inc., Portland, OR (booknews.com)
