Paris in the century around 1789 saw the first lightning conductor, the first flight, the first estimate of the speed of light and the invention of the tin can and the stethoscope. The metre replaced the yard and the theory of evolution came into being. The city was saturated in science and many of its monuments still are. The Eiffel Tower, built to celebrate the Revolution's centennial, saw the world's first wind-tunnel and first radio message, and first observation of cosmic rays. Perhaps the greatest Revolutionary scientist of all, Antoine Lavoisier, founded modern chemistry and physiology, transformed French farming, and much improved gunpowder manufacture. His political activities brought him a fortune, but in the end led to his execution. In this enthralling and timely book, Steve Jones shows how wrong this was and takes a sideways look at Paris, its history, and its science, to give a dazzling new insight into the City of Light.
