• So often mathematics problems yield exact answers. It is a breath of fresh air (pun intended) to work on a problem that does not have an exact answer. Similar problems, that rely on estimates, are known as Fermi problems. The classic Fermi problem, generally attributed to Enrico Fermi, an Italian physicist, is 'How many piano tuners are there in Chicago?' A typical solution to this problem involves multiplying a series of estimates that yield a good approximation of the actual answer.

I initially heard this book described on the Grammar Girl podcast and immediately went to find out more about it. I now have it on my Christmas present wish list and am looking forward to receiving a copy (hint!).

"Caleb Everett provides a fascinating account of the development of human numeracy, from innate abilities to the complexities of agricultural and trading societies, all viewed against the general background of human cultural evolution. He successfully draws together insights from linguistics, cognitive psychology, anthropology, and archaeology in a way that is accessible to the general reader as well as to specialists." more...
