We've come a long way from guesses at the Earth's shape (flat) and it's place in the Universe (dead centre). Thanks to ideas of pure genius and accidental realisations, we now see the world completely differently, able to do more and go further. This book highlights the key moments in a century that has seen more progress than any other. Written with flair and insight, it covers widely familiar inventions, great scientific thinkers such as Einstein and Stephen Hawkings, ground-breaking discoveries and mind-boggling theorems that altered the way we see the world, and the less well-known moments that provided the foundations for later discoveries. With all the key moments placed in their social, historical and scientific contexts, the book brings the complexities and secrets of the Universe, the world and everything in them to within your grasp.
