Perhaps you thought that you were far from mathematics, and all you learned from school was “Pythagorean pants are equal in all directions.” If you always thought that you wouldn’t need mathematics, then it’s time to disabuse yourself of that. In the book “Mathematics for Geeks” by Raphael Rosen, you will not only learn a lot of new things, but also in practice you will understand that every day is full of mathematics - round manhole covers are round for a reason, the Romanesco cabbage that so attracts our attention, even your shoelaces , which have a lot in common with your DNA or even your envy on social networks has mathematical roots. After reading, you will be able to use terms such as Dewey classification, Fibonacci numbers, Nash equilibrium, Monty Hall paradox, chaos theory in conversation, prepare for the text Turing, find out how a film wins an Oscar, and what the Brazil nut effect is.
