As I mentioned in my review of Volume 1 of "Physics for Entertainment" I thought this was a charming book containing scores of stories illustrating why things act the way they do in nature, such as sound waves, light waves, all sorts of natural phenomena. The author provides endlessly entertaining examples and explanations of so many things we usually take for granted or don't consider or stop to question in everyday life.
Here is a quote in connection with measuring air temperature: "...it is only in the shade that a thermometer will register the right temperature of the air. After all if it were exposed to the sun, it might be heated up to a much greater temperature than that of the surrounding air."
Also, a quote from section about dry ice, called "Cold from Coal:" "Dry ice is derived from liquid carbon dioxide by fast vaporization under a reduced pressure."
And in a discussion of radium: "Radium...emits three types of rays--respectively, alpha, beta and gamma rays."
In a section discussing how to determine the age of the Earth: "...the emission of ...alpha rays....a beam of charged particles of matter or atoms of the light inert gas helium--by the decaying atoms. As these charged particles possess enormous velocities, when released they lose their positive charge and settle down in the mineral as particles of ordinary helium--which explains why we find helium in all radioactive minerals."
All in all, I was entranced with this two-volume book. There was so much I didn't know.. or maybe had forgotten. Since the last time I was in school was 45 years ago, and since then I must say I have not in general read much on physics or math, "Physics for Entertainment" was a fun way to brush up on these topics. I think I could actually feel my brain getting much-needed exercise when reading this two-volume book!
