Quadratic equations, Pythagoras’ theorem, imaginary numbers, and pi — you may remember studying these at school, but did anyone ever explain why? Never fear — bestselling science writer, and your new favourite maths teacher, Michael Brooks, is here to help.

In The Maths That Made Us, Brooks reminds us of the wonders of numbers: how they enabled explorers to travel far across the seas and astronomers to map the heavens; how they won wars and halted the HIV epidemic; how they are responsible for the design of your home and almost everything in it, down to the smartphone in your pocket. His clear explanations of the maths that built our world, along with stories about where it came from and how it shaped human history, will engage and delight. From ancient Egyptian priests to the Apollo astronauts, and Babylonian tax collectors to juggling robots, join Brooks and his extraordinarily eccentric cast of characters in discovering how maths made us who we are today.

‘At school, many of us wondered about the point of geometry, calculus, and algebra. Brooks shows how the childhood question “What’s the point of this?” can be reframed: esoteric concepts such as imaginary numbers, cryptography, and the semi-mystical digits of pi are revealed to be the essential building blocks of the 21st century.’

‘An alternative textbook that suggests a new way of thinking about maths, and a more congenial way of teaching it — as not simply an abstract science but as a cultural achievement, an indelible and indispensable part of human history.’

‘A more or less chronological history and compelling case that advances in mathematics provided the foundation for the advance of civilisation … An unabashed lover of mathematics, Brooks refuses to take the traditional pop writer’s pledge to eschew equations. Most readers will follow his description of ancient navigation across the Mediterranean and the birth of linear perspective in Renaissance Italy, but when he turns his attention to calculus, logarithms, statistics, and cryptography, there is no shortage of complex equation … Not a mathematics-is-fun romp but a serious, persuasive effort to describe how its discoveries paralleled human progress.’

‘Moving from ancient Egyptian priests to a hobbyist who solved a mapmaking puzzle that confounded NASA and the US Geological Survey, science writer Brooks aims to persuade readers that mathematics was one of the great innovations that made civilisation happen.’

"

‘He begins by diligently explaining the basics of algebra, arithmetic, calculus, and geometry, and introducing key figures in math’s history … Brooks uses the work of these thinkers to break down the math behind facets of everyday life: he describes the statistics that underlie life expectancies; the equations that allow scientists to understand the cosmos; and the imaginary numbers that give guitar amplifiers their power … It’s a show-stopping paean to the wonder of numbers.’
