It All Adds Up: The Story of People and Mathematics

‘Fascinating … so enlightening that suddenly maths doesn’t seem so fearsome as it once did’ SIMON WINCHESTER

From Aristotle to Ada Lovelace: a brief history of the mathematical ideas that have forever changed the world and the everyday people and pioneers behind them. The story of our best invention yet.

From our ability to calculate the passing of time to the algorithms that control computers and much else in our lives, numbers are everywhere. They are so indispensable that we forget how fundamental they are to our way of life.

In this international bestseller, Mickaël Launay mixes history and anecdotes from around the world to reveal how mathematics became pivotal to the story of humankind. It is a journey into numbers with Launay as a guide. In museums, monuments or train stations, he uses the objects around us to explain what art can reveal about geometry, how Babylonian scholars developed one of the first complex written languages, and how ‘Arabic’ numbers were adopted from India. It All Adds Up also tells the story of how mapping the trajectory of an eclipse has helped to trace the precise day of one of the oldest battles in history, how the course of the modern-day Greenwich Meridian was established, and why negative numbers were accepted just last century.

This book is a vital compendium of the great men and women of mathematics from Aristotle to Ada Lovelace, which demonstrates how mathematics shaped the written word and the world. With clarity, passion and wisdom, the author unveils the unexpected and at times serendipitous ways in which big mathematical ideas were created. Supporting the belief that – just like music or literature – maths should be accessible to everyone, Launay will inspire a new fondness for the numbers that surround us and the rich stories they contain.

• BIG PLATFORM AND ENTHUSIASTIC AUTHOR: Mickael is young, enthusiastic and really approachable. He takes part in numerous projects aimed at popularizing mathematics among young people and the general public. He runs Micmaths, a YouTube channel that has now garnered more than 315,500 subscribers and generated 24 million views. He has a lot of energy and would perform very well in events.

• A NEW WAVE OF MATHEMATICS BOOKS: This book will sit in the tradition of titles that popularize mathematics for the general public in an approachable and fun way. For readers of: Alex Bellos (230k), The Number Mysteries: A Mathematical Odyssey Through Everyday Life by Marcus du Sautoy (22k), history and science enthusiasts, and readers of Christophe Galfard.

• GLOBAL FEMINIST INTELLECTUAL HISTORY: This book debunks the idea of science as a European idea, showing the truly global scope of the discipline. It also showcases women and in their absence investigates the issue of gender. It would do really well on these sort of reading lists and with book clubs.
