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 \u003ci\u003eNo Shadow of a Doubt\u003c\/i\u003e, 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. \u003cp\u003e\u003c\/p\u003eThe 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. \u003cp\u003e\u003c\/p\u003eBy chronicling the expeditions and their enormous impact in greater detail than ever before, \u003ci\u003eNo Shadow of a Doubt\u003c\/i\u003e reveals a story that is even richer and more exciting than previously known.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Daniel Kennefick\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 0691183864\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9780691183862\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Princeton University Press\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 04\/30\/2019\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 416\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Hardcover\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 1.85lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.40h x 6.50w x 1.50d\u003cbr\u003e\u003cbr\u003e\u003cb\u003eReview Citation(s): \u003c\/b\u003e\u003cbr\u003e\u003ci\u003eChoice\u003c\/i\u003e 08\/01\/2019","brand":"Daniel Kennefick","offers":[{"title":"Hardcover","offer_id":43981106610431,"sku":"9780691183862","price":29.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_ae7ef866-4c9b-4240-b0d5-284fdb68ac0d.jpg?v=1683253691","url":"https:\/\/www.whiterainbookhouse.com\/products\/no-shadow-of-a-doubt-daniel-kennefick-9780691183862","provider":"WR Book House","version":"1.0","type":"link"}
