Mathematicians don't work with numbers (Q6553933)

The book ``Mathematicians don't work with numbers'' is an agile and engaging introduction to different branches of mathematics, from public key encryption to chaotic models, from proof techniques to aesthetics in mathematics. It starts from the point of view of a citizen with a high-school math education, wondering about the use of mathematical concepts in everyday life. Each chapter is a little piece added to the reality's understanding. The non-expert reader can enjoy jargon-free chapters, while the more expert reader can appreciate the way to present the topics, along with their precision. The book returns circularly to the point of view of the citizen, who, by the end of the reading, made the connection between scheduling tasks and graph theory, pricing business and game theory, and news and actual danger-rating scale. At the end of the book, we find a synthetic list of mathematical branches and the domains of human knowledge where they have an impact and a table of approximated conversions between metric and imperial units. A section on category theory would have completed the presentation; maybe it could be considered by the author for a second edition of the book.
