Title: Excellent writing but .... no pictures
Review: This book is about the theory that, over 600 million years ago, the earth underwent periods when it was completely covered with ice, hence, Snowball Earth. Although many scientists have contributed to this theory over the past few decades, the book focuses mainly on the efforts of Dr. Paul Hoffman, the main scientist responsible for developing and promoting the theory, thus raising its status to level that it has today. This is a very well-written book. It vividly describes the way in which science works, as well as the fact that scientists are all too human. It also contains well-written discussions on the science involved. Such a book should contain diagrams, figures, charts, photos, maps, etc., to better illustrate the locations, ideas and facts presented in the text. Unfortunately, the book contains none of the above - no picture whatsoever; if it did, I would have easily given it 5 stars. Despite this shortcoming, the book is definitely worth the read.
