Presents an illustrated look at computers, describing how they were invented, how they work, the different types, how they are used in everyday life, and how they affect the future.
". . . tells the story of algebra and calculus to explore the . . . evolution of mathematics through the ages. Along the way, readers will meet with geniuses, such as Diophantus and Newton, who figured out how to turn math problems into general techniques that worked whatever the situation. Readers will not only learn how computer chips process their programs, but also how a smartphone knows where it is, what the link is between snowflakes, cannonballs and wine barrels, and how Carl Gauss figured out how to add up all the numbers between 1 and 100 in less than a minute-when he was just 10 years old!"--Provided by publisher.
"[This book] starts with the simple task of dividing up ground for making fields and a building--the word geometry means 'Earth measurement.' It ends by navigating us through new universes constructed entirely from mathematics, strange worlds where curved lines are straight, and a donut and coffee cup are exactly the same shape. Along the way, we'll see just how lines, surfaces, and spaces can add up to reveal other ways of seeing the world"--Back cover.
