Empire of the Sum

The hidden history of the pocket calculatorβ€”a device that ushered in modern mathematics, helped build the atomic bomb and went with us to the moonβ€”and the mathematicians, designers and inventors who brought it to life

Starting with hands, abacus, and slide rule, humans have always reached for tools to simplify maths. Pocket-sized calculators ushered in modern mathematics, helped build the atomic bomb, took us to the bottom of the ocean, and accompanied us to the moon. The pocket calculator changed our world, until it was supplanted by more modern devices that, in a cruel twist of irony, it helped to create. The calculator is dead; long live the calculator.

In this witty mathematical and social history, Keith Houston transports readers from the nascent economies of the ancient world to World War II, where a Jewish engineer calculated for his life at Buchenwald, and into the technological arms race that led to the first affordable electronic pocket calculators. At every turn, Houston is a scholarly, affable guide to this global history of invention.

Empire of the Sum will appeal to maths lovers, history buffs, and anyone seeking to understand our trajectory to the computer age.
