"British astronomer Arthur Stanley Eddington photographed the 1919 solar eclipse to prove Einstein's theory of general relativity by demonstrating that the sun's gravity could pull and bend light"--Provided by publisher.

On their 100th anniversary, the story of the extraordinary scientific expeditions that ushered in the era of relativityIn 1919, British scientists led extraordinary expeditions to Brazil and Africa to test Albert Einstein?s revolutionary new theory of general relativity in what became the century?s most celebrated scientific experiment. The result ushered in a new era and made Einstein a global celebrity by confirming his dramatic prediction that the path of light rays would be bent by gravity. Today, Einstein?s theory is scientific fact. Yet the effort to ?weigh light? by measuring the gravitational deflection of starlight during the May 29, 1919, solar eclipse has become clouded by myth and skepticism. Could Arthur Eddington and Frank Dyson have gotten the results they claimed? Did the pacifist Eddington falsify evidence to foster peace after a horrific war by validating the theory of a German antiwar campaigner? In No Shadow of a Doubt, Daniel Kennefick provides definitive answers by offering the most comprehensive and authoritative account of how expedition scientists overcame war, bad weather, and equipment problems to make the experiment a triumphant success.The reader follows Eddington on his voyage to Africa through his letters home, and delves with Dyson into how the complex experiment was accomplished, through his notes. Other characters include Howard Grubb, the brilliant Irishman who made the instruments; William Campbell, the American astronomer who confirmed the result; and Erwin Findlay-Freundlich, the German whose attempts to perform the test in Crimea were foiled by clouds and his arrest.By chronicling the expeditions and their enormous impact in greater detail than ever before, No Shadow of a Doubt reveals a story that is even richer and more exciting than previously known.

"[Discusses] the birth of a world-changing idea, relativity, and how it was shaped by the social upheaval and bloody horror of the First World War"--OCLC.

When one thinks of Georges Seurat, one artistic technique should come to mind: pointillism. Through Seurat's study of color and light, he came to use tiny dots to create gorgeous, unique colors. Readers see full-color photographs of some of his most famous pieces, such as A Sunday Afternoon on La Grande Jatte. Close-up images of small parts of the works call readers' attention to interesting details, like the child in this painting who's looking straight out of the canvas. Through clear instructions, readers can learn how to do a pointillist painting, too--if they have the patience!.

Recounts the rivalry between Subrahmanyan Chandrasekhar, who developed the first mathematical description of black holes, and Sir Arthur Eddington, one of the greatest astrophysicists of the day, discussing how their theories contradicted and inspired one another.
