The Human Cosmos: Civilization and the Stars
Dutton (September 1, 2020), 399 pages
Kindle edition $14.99, Amazon hardcover $24.21
The Human Cosmos is a look at how humankind has looked at the heavens through the ages.
The author describes how the earliest civilizations tracked the movement in the sky and how a king’s astronomers could help him solidify his power. The ability to predict an eclipse could reinforce his legitimacy, while an error could make him vulnerable.
The book goes on to follow human achievements in astronomy through classical, medieval, and early modern times. Marchant describes how observing the cosmos influenced the transition from the American colonies to the new United States. Oddly, the author goes off on a tangent recounting the events of the American and French revolutions, the only connection seemingly being that Thomas Paine used some of Newton’s principles in his writing.
But when she returns to the world of astronomy the book gets interesting again. She describes the current science and shows how a meteorite found in Antarctica turned out to be a chunk that was blown off of Mars. She also talks about pulsars and writes about the desire of many to believe that the signals occurring at precisely timed intervals were artificial and the creation of an intelligent source out there. So far, most of the signals seem to be natural events, emitting from rapidly spinning stars near the end of their life cycles. She does tantalize us, however, by saying a couple of the detected signals have not been adequately explained.
If you enjoy astronomy and/or the history of science you will like The Human Cosmos.
