'There is no author whose books I look forward to more' Bill Gates 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. 'Vaclav Smil is a phenomenon with an appetite for facts over prejudice and fashion. Essential reading for anyone who cares about the future' Lord Norman Foster.
