This book will change your view of the world. Jordan Ellenberg, professor of mathematics and author of the MYTH bestseller How Not to Be Wrong, shows the power of geometry, a science that only seems theoretical. Mathematics is called the queen of sciences, and part of it, geometry, lies at the basis of understanding the world. A professor of mathematics at the University of Wisconsin-Madison and a fellow of the American Mathematical Society, Jordan Ellenberg has been popularizing his favorite discipline for more than 15 years. In this book, with his usual ease and humor, he says that geometry does not just measure the world - it explains it. She is not somewhere out there, outside of space and time, but here and now, with us. It helps to see and understand hidden relationships and algorithms in everything: in society, politics and business. Geometry is hidden behind the most important scientific, political and philosophical problems. For whom is the book? For those who want to rediscover geometry and learn about this fascinating science what was not taught at school. For everyone who is interested in looking at the world from a new perspective. Published in Russian for the first time.
