The New York Times bestselling author returns with a mind-opening exploration of how size defines life on Earth.Explaining the key processes shaping size in nature, society and technology, Smil busts myths around proportions - from bodies to paintings and the so-called golden ratio - tells us what Jonathan Swift got wrong in Gulliver's Travels - the giant Brobdingnagian's legs would buckle under their enormous weight - and dives headfirst into the most contentious issue in ergonomics: the size of aeroplane seats.It is no exaggeration to say this fascinating and wide-ranging tour de force will change the way you look at absolutely everything.
