Science and Skeptics Book Club - "Caesar’s Last Breath: Decoding the Secrets of the Air Around Us." Sam Kean.

Caesar’s Last Breath: Decoding the Secrets of the Air Around Us. Sam Kean. Kean tells us the story of the air we breathe, which, it turns out, is also the story of the earth and our existence in it. With every breath, you literally inhale the history of the world. Sextillions of molecules entering or leaving your lungs at this moment might well contain traces of Caesar’s last breath and particles exhaled by dinosaurs. Kean reveals how the alchemy of air reshaped continents and continues to influence everything we do.
