Each month, Hamilton RASC librarian Bruce Murray has reviews a book. This month it is “Astrophysics for People in a Hurry” by Neil de Grasse Tyson.
There are 12 chapters covering various astrophysics’ topics written in an easy to read format. The first chapter describes the period from the big bang to the start of life on earth in 18 pages .
Some of the interesting things learned included information on which of the 118 elements in the periodic table how many were formed in the Big Bang (Hydrogen, Helium and Lithium; all the others were forged within stars).
I personally enjoyed the chapters on dark matter and dark energy. Dark Matter is used to explain the 6x addition gravity from visible matter and Dark Energy is used to explain the theoretical to explain the expanding universe
