What distinguishes life from its nonliving ingredients? How could life arise from the lifeless? These questions have vexed philosophers and scientists for more than 2,500 years. Bio-besotted physicist Peter Hoffmann wrote Life’s Ratchet to get to the beating heart of the matter. After a lively, lucid grand tour of the controversy’s history—featuring prescient thinkers you’ve probably never heard of (Julien Offray de La Mettrie? D’Arcy Wentworth Thompson?)—Hoffman arrives at modern molecular biology and the technological breakthroughs, such as atomic force microscopy, that enable us to see the very atoms of a cell.

The secret of life, he says, is not some “vital force,” but the unique operations of the second law of thermodynamics at the nanoscale, where molecular machines from kinesins to DNA synthase, fueled by ATP, can harness the energy of the “molecular storm”—the random bombardment of water molecules at jet-plane ...
