Two very good books on Special Relativity were written by the same professor at the beginning of his career and at the end of his career. Together they show how much America has changed between 1968 when the first book was written and 2004 when the second was published.
In the late 1960s during the zenith of science in American culture, N. David Mermin, a young professor of physics at Cornell University wrote SpaceTime and Special Relativity. I love this book.
Mermin wrote the book after hosting a summer seminar for high school physics teachers. He taught the group special relativity with the goal of giving them the information they needed to teach special relativity in their high schools. Mermin’s book was published the year before the moon landing.
He believed that special relativity could be taught and understood at the high school level because the only math required is algebra and trigonometry. In 2005, as he neared retirement, Mermin published a new edition of the book titled It’s About Time.
The new edition reflected almost 40 years of teaching a course in science for non-science majors. In the preface, he also wistfully admitted his dream of high school kids learning special relativity had evaporated. The new edition is a better book with better examples, but I prefer the first one.
Mermin has an interlude between chapters 10 and 12, a "Relativisitic Tragicomedy" in which he makes fun of Absolutists. He attacks his anti-science enemies with the same confidence and brio he brings to the subject of the book. For me the book helped me to see the real flaw in the Young Earth Creationist arguments and at the same time gave me a picture of God in the universe that Einstein gets beautifully right and the Creationists get horribly wrong.
Before the new book was published, I wrote Mermin a letter telling him what I saw in his book. He wrote a long letter back telling me he was happy to hear what I found in the book and saying if he writes a new edition, it would not have a Chorus. It doesn’t.
Thinking about these books together reminded me how different Life, the Universe, and Everything looked when America was the world center of science and innovation.
