A Short History of Nearly Everything

In A Short History of Nearly Everything, Bill Bryson starts with the beginning of the universe and works his way down. He laments the poor stats of science textbooks. They often have a few diagrams that attract you to the possibilities of learning, then let you down with very poor text. In this work, he tries to provide an accessible "history" of the world. It starts with the big bang, works through how the universe, suns and planets were formed, then goes down to describe life on earth. From here, it goes through the initial history of organisms, the evolution to different species, and the many extinction events that have taken place and the new species that have come to fill voids. The narrative follows a dual chronology approach. The author discusses key events in rough chronology that the occurred. Within the discussion of the events, he discusses the way that our knowledge of the events has unraveled, with special attention to the key figures in the discovery process. In many of the cases the "first discoverer" is disregarded by society, and only comes to light after somebody else has popularized and attached his name to the discovery (it is almost always a he). The earth has often been much hotter than it is today. (We are in part of a long term ice age.) However, global warming has a lot of uncertainties that could make matters worse. The book ends with a look at homo sapien and how he has come on the scene, with both the ability to both understand and destroy the world.
