We all know the earth is round. But HOW do we know? Join intrepid young scientist-adventurer Joulia Copernicus as she takes readers on a historical journey through time and space. From jumping on board Columbus's ship to planet-hopping in the outer reaches of our solar system, Joulia explains with humor and wit the ins and outs of how we learned that the earth is round.

People used to think that Earth was flat, but now we know it isn’t. How did we find out Earth is actually a sphere? How did science help us understand the shape of our planet? Readers will delight in exploring the history and science behind Earth’s spherical shape. They’ll learn how satellite images and modern technology give us an image of the Earth. Readers will also learn all about early scientists and how they gradually came to enlighten others that the Earth wasn’t flat. Clear diagrams and fascinating sidebars help explain this important science topic, as supplemental science experiments give readers the hands-on experience they need to grasp the topic.

A colorfully illustrated biography of the Greek philosopher and scientist Eratosthenes, who compiled the first geography book and accurately measured the globe's circumference.

Reveals the facts behind the deceiving myths that have been professed about Columbus and his time.

Contrary to popular belief fostered in countless school classrooms the world over, Christopher Columbus did not discover that the earth was round. The idea of a spherical world had been widely accepted in educated circles from as early as the fourth century B.C. Yet, bizarrely, it was not until the supposedly more rational nineteenth century that the notion of a flat earth really took hold. Even more bizarrely, it persists to this day, despite Apollo missions and widely publicized pictures of the decidedly spherical Earth from space. Based on a range of original sources, Garwood's history of flat-Earth beliefs---from the Babylonians to the present day---raises issues central to the history and philosophy of science, its relationship to religion and the making of human knowledge about the natural world. Flat Earth is the first definitive study of one of history's most notorious and persistent ideas, and it evokes all the intellectual, philosophical, and spiritual turmoil of the modern age. Ranging from ancient Greece, through Victorian England, to modern-day America, this is a story that encompasses religion, science, and pseudoscience, as well as a spectacular array of people and places. Where else could eccentric aristocrats, fundamentalist preachers, and conspiracy theorists appear alongside Copernicus, Newton, and NASA, except in an account of such a legendary misconception? Thoroughly enjoyable and illuminating, Flat Earth is social and intellectual history at its best.
