What can maths tell us about art and design? Professor John D. Barrow has all the answers. In 100 Essential Things You Didn't Know You Didn't Know About Maths and the Arts , he shows us that mathematics and the arts are not so far removed from each other. He takes us on a 100-step tour, guiding us through art forms as various as sculpture, literature, architecture and dance, and reveals what maths can tell us about the mysteries of the worlds of art and design. We find out why diamonds sparkle, how many words Shakespeare knew and why the shower is the best place to sing. We discover why an egg is egg-shaped, why Charles Dickens crusaded against maths and how a soprano can shatter a wine glass without touching it... Enlivening the everyday with a new way of looking at the world, this book will enrich your understanding of the maths and art that surround us in our day-to-day lives.
