Book review – The Tectonic Plates are Moving!

What has plate tectonics ever done for us? Not having studied geology, I have a basic understanding of the movement of earth’s continents, but this book made me appreciate just how much of current geology it underpins. Marine geophysicist Roy Livermore, who retired from the British Antarctic Survey in 2006 after a 20-year career, convincingly shows here that the discovery and acceptance of plate tectonics was a turning point in geology, on par with Darwin’s formulation of evolution by natural selection. To paraphrase evolutionary biologist Theodosius Dobzhansky: nothing in geology makes sense except in the light of plate tectonics.

Book review – The Equations of Life: The Hidden Rules Shaping Evolution

Starting your book blurb by asking why gazelles have legs rather than wheels is a suitably out-there question to immediately grab a reader’s attention. A more pertinent question then; why is all life based on carbon rather than silicon? In The Equations of Life, Charles Cockell takes the reader on a giddy tour down the organisational hierarchy of life – from sociobiology to subatomic particles – to show that nature is far more predictable and understandable than it might appear at first blush. His eloquent answer to above and other why questions? “Because physics is life’s silent commander”.

Book review – Planet of Microbes: The Perils and Potential of Earth’s Essential Life Forms

What unites deep subterranean caves, hydrothermal vents in the deep sea, our guts, cloud formation, geochemical processes, and astrobiology (the search for life beyond our planet) to name but a few things? Microbes. The tiny, single-celled organisms that we cannot see with the naked eye are everywhere. With Planet of Microbes, Ted Anton makes the point that this world is really theirs, and takes the reader on a tour of the rapid increase in our understanding of their importance, focusing on three major subjects.
