It would seem that love and mathematics have in common? The author of the book, professor of mathematics at the University of London Hannah Fry, convincingly proves that mathematical formulas are quite capable of telling us something new about love and relationships. Our feelings may be chaotic and difficult to analyze, but mathematics has long learned to work with chaos—whether we are talking about the behavior of elementary particles or demographic problems. No matter how bizarre and changeable the laws of love may be, mathematics is able to not only describe them, but also offer a number of practical ideas - from the theory of flirting and the optimal behavior algorithm at a party to predicting the number of guests at a wedding and even their seating arrangement at the table. Mathematics is the language of the universe. So why not talk about love in this language? The publishing design is preserved in pdf A4 format.
