I just finished reading The best American Science and Nature writing 2006. This is the seventh version of this book series and I definitely wish I had found out about it earlier. Each book is made up of about 25 articles that a guest editor selects from about a hundred articles chosen by Tim Folger.
The 2006 edition is edited by Brian Greene who just happens to be one of my favorite physics writers. The articles span everything from bittorrent and blogs to animal psychology, anthropology and advanced physics. Coming from sources like Scientific American, The New York Times and Wired, most articles are easy to read and don't get detailed to the point of being boring. I had actually managed to read some of the articles already, but the others were a great way for me to be introduced to areas of science I knew very little about.
Some of my favorite articles are Dr Ecstasy about the chemist Alexander Shulgin, His brain, her brain about the differences between the male and female brain, and The coming death shortage describing how the increasing life expectancy of humans will affect us.
I encourage everyone interested in widening their scientific horizons to read this book. It's only 280 pages long and reading one chapter per night before falling asleep was perfect. 9 out of 10 points for this book from me.
