Sharks have been on this planet for over 400 million years, so there is a lot they can teach us about survival and adaptability. For example: how do sharks, which unlike other fish are denser than water, stay afloat? They keep moving. When Jasmin Graham, an award-winning young shark scientist, started to feel that the traditional path to becoming a marine biologist was pulling her under, she remembered this important lesson: keep moving forward.

Mathematics shapes almost everything we do. But despite its reputation as the study of fundamental truths, the stories we have been told about it are wrong—warped like the sixteenth-century map that enlarged Europe at the expense of Africa, Asia and the Americas. In The Secret Lives of Numbers, renowned math historian Kate Kitagawa and journalist Timothy Revell make the case that the history of math is infinitely deeper, broader, and richer than the narrative we think we know.

What has counting meant to different cultures and different individuals? In this book, historian and mathematician Benjamin Wardhaugh explores stories from all over the world and from every period of human history, from the African Stone Age to cyberspace; from Assyrian kings to Chinese peasants. Weaving these histories together, Wardhaugh shows the ways in which counting has been continually reinvented over time, through language, writing, counters and machines.
