Mathematics is called the queen of sciences, and part of it - geometry - underlies the understanding of the world. Professor of mathematics at the University of Wisconsin at Madison, researcher at the American Mathematical Society Jordan Ellenberg has been popularizing his favorite discipline for more than 15 years. In this book, with his inherent lightness and humor, he reveals that geometry doesn't just measure the world - it explains it. She is not somewhere there, outside of space and time, but here and now, with us. It helps to see and understand hidden relationships and algorithms in everything: society, politics and business.
