When did people tie the first knots? Why was the first female mathematician killed? Is it possible to turn a sphere inside out? These are just some of the questions answered in Clifford Pickover's beautifully illustrated book. The author reveals the most significant milestones and the most fascinating and amazing ideas in the development of mathematics, reveals the magic and secrets of the queen of sciences. After all, mathematics permeates all areas of science. It can be used to explore and explain the color of sunset skies and the architecture of our brains, and it can help study subatomic quantum structures and image distant galaxies. The book "GREAT MATH" is a fascinating journey through 250 mathematical discoveries: from the pedometer of ancient ants and the first abacus to the discovery of fractals and the search for new dimensions. The book also explores the ideas of eminent thinkers, from Pythagoras and Euclid to the icon of modern mathematics, Martin Gardner, and the cosmologist Max Tegmark. Well-known formulas and mathematical concepts are accompanied by interesting facts from the lives of mathematicians and information about the practical implementation of the theorems they proved. Articles about mathematical discoveries are arranged in chronological order and accompanied by colorful illustrations.
