How does mathematics enable us to send pictures from space back to Earth? Where does the bell-shaped curve come from? Why do you need only 23 people in a room for a 50/50 chance of two of them sharing the same birthday? In "Strange Curves, Counting Rabbits, and Other Mathematical Explorations", Keith Ball highlights how ideas, mostly from pure math, can answer these questions a...(展开全部)
