Benjamin Crowell undertakes the subject of physics from a rather profound perceptive, a lot of thought provoking segments in which the concepts take many different forms, which is great to get a good hold of the ideas necessary to succeed in understanding physics at college level. Reading intensive, in which examples stretch the concepts rather than try to mechanically drive you through steps. Excellent book if you really want to learn physics.

Page 16 - Newton was not the first of the age of reason. He was the last of the magicians, the last of the Babylonians and Sumerians, the last great mind which looked out on the visible and intellectual world with the same eyes as those who began to build our intellectual inheritance rather less than 10,000 years ago.

Page 72 - The general conclusion which must, I think, be drawn from this collection of facts is, that electricity, whatever may be its source, is identical in its nature. The phenomena in the five kinds or species quoted, differ, not in their character but only in degree; and in that respect vary in proportion to the variable circumstances of quantity and intensity...

Page 30 - To present direct and tangible demonstration, through the study of the behavior in electrical and gravitational fields of this oil drop, carrying its captured ions, of the correctness of the view advanced many years ago and supported by evidence from many sources that all electrical charges, however produced, are exact multiples of one definite elementary electrical charge; or, in other words, that an electrical charge, instead of being spread uniformly over the charged surface has a definite granular...
Page 26 - ... which must be overthrown, surmounted, or turned, if chemical science is ever to develop into a definite, an organised unity. This barrier is nothing less than the chemical elements commonly so called, the bodies as yet undecomposed into anything simpler than themselves. There they extend before us, as stretched the wide Atlantic before the gaze of Columbus, mocking, taunting, and murmuring strange riddles, which no man yet has been able to solve.
