Seven Rivers: a History of Mathematics with Temperature in One Step

This is not the kind of mathematics book you wanted to tear up when you were in school, but a "record of grievances and feuds in mathematics" spanning five thousand years. It doesn't talk about test points or piles of formulas, it just talks about how a group of paranoiacs, unlucky people, and geniuses used numbers to step by step advance human civilization to what it is today. The whole play unfolds along seven rivers of love and death: ·The battle of counting: From tying knots to note notes all the way to computers, binary numbers, Arabic numerals, and finally smartphones, you will have a lot of fun every day. ·Battle of Equations: From ancient Egypt's "blind guessing" to young Galois' creation of group theory, there are various academic conflicts and competition for starting rights. ·Battle of Infinity: Zeno's "tortoise can't catch up" has tortured mankind for two thousand years. Cantor said "infinity is also divided into big and small" and was sprayed until he had a mental breakdown. ·The battle of shapes: From Euclid's triangle drawing to Riemann's statement that "space is curved", and later supporting Einstein's general theory of relativity, geometry not only paved the floor, but also paved the universe. ·Battle of Guessing Numbers: Judge Fermat wrote "I have proved it but cannot write it down" on the side of his book, which drove the whole world crazy for three hundred years. In the end, Wiles went into seclusion for seven years to solve it. ·Battle of Logic: Hilbert shouted "We must know", but Godel gave him a blow at the age of 25 - any self-consistent system has unprovable truth. ·Application War: How mathematics has transformed from measuring land into navigation, payment, and AI algorithms on your mobile phone, supporting the entire online civilization. Seven rivers, each going his own way and visiting each other. There are no born gods, only generations of mortals who have taken up the torch of their predecessors and continued to move forward while cursing "it's too difficult".
