Mathematics, or what is common between cabbage, secret cipher and art gallery?

What is mathematics for you? Numbers, boring formulas and incomprehensible theorems ... or, conversely, inspiring graphic lines, perfection of snowflakes and music of your favorite poem? This book will find how to surprise those who are not friendly with the queen of sciences, and those who have already managed to fall in love with it! The author of the book - the teacher and popularizer of science Sergey Korneev - offers to wear magic glasses and see the magic of mathematics where there should not be numbers and formulas: in the football stadium, in the art gallery, in an encrypted message and even on a plate with cabbage. Mathematics is not scary, but terribly interesting.
