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 – The Spinning Magnet: The Force That Created the Modern World – and Could Destroy It
If you have used a compass, you will know our planet has a magnetic North and South pole. You might even be aware that the geographical and magnetic poles are not exactly in the same location. The magnetic poles have a tendency to wander with time. They can even swap places, and we have evidence of a long history of such geomagnetic reversals in the rock record. But how does this happen? And what would the consequences be if this happened today? Earth’s magnetic field offers protection against radiation from outer space, primarily from the sun, so if this field weakens or changes, what will happen to us and our electrical infrastructure? Join science journalist Alanna Mitchell as she explores this topic and delves into the history of electromagnetism.
