Explaining the Universe: The New Age of Physics
Princeton University Press, 05.06.2018 - 226 Seiten
In this fascinating book, John Charap offers a panoramic view of the physicist's world as the twenty-first century opens--a view that is entirely different from the one that greeted the twentieth century. We have learned that the universe is billions of galaxies larger than we imagined--and billions of years older. We know more about how it came to be and what it is. Because of physics, we live in a world of greater danger and more convenience, smaller particles and bigger ideas.

It is wonderful enough that matter, in all its variety of forms—from hydrogen, the simplest and most common element, to the most complex molecules, like the DNA that encodes our genetic inheritance—is made from atoms.
In this way the pharmacologist, for example, may design a drug using empirical rules about the structure of molecules derived from more basic chemistry; these in turn have a theoretical framework built upon the behavior of electrons and ...
The air in your room is made from molecules that collide and scatter from one another in a way well described by mechanics. ... But it makes no sense whatever to speak of the temperature of a single molecule, nor even of a half a dozen ...
At this distance in time, it is hard to recapture the passion with which physicists—and chemists—debated the existence of atoms and molecules. Was one to accept the particulate nature of matter as a reality, or merely a “conventional ...
