How was he able to do this when most scientists didn't even believe that light traveled? Like many paradigm-shattering discoveries, Romer's was accidental. Night after night he was timing the disappearance and reappearance of Jupiter's moon Io behind the huge, distant planet. Eventually he realized that the discrepancies in his measurements could have only one explanation: Light had a speed, and it took longer to reach Earth when Earth was farther from Jupiter. All he needed then to calculate light's speed was some fancy geometry.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Mark Weston\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 0884485455\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9780884485452\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Tilbury House Publishers\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 03\/12\/2019\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 32\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Hardcover\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 1.10lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.10h x 11.20w x 0.40d\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAccelerated Reader:\u003c\/b\u003e\u003cbr\u003e\u003cb\u003eReading Level:\u003c\/b\u003e 5.1\u003cbr\u003e\u003cb\u003ePoint Value:\u003c\/b\u003e 1\u003cbr\u003e\u003cb\u003eInterest Level:\u003c\/b\u003e Middle Grade\u003cbr\u003e\u003cb\u003eQuiz #\/Name: \u003c\/b\u003e504184 \/ Finding the Speed of Light: The 1676 Discovery That Dazzled the World\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eReview Citation(s): \u003c\/b\u003e\u003cbr\u003e\u003ci\u003eKirkus Reviews\u003c\/i\u003e 02\/01\/2019 pg. 163\u003cbr\u003e\u003ci\u003eSchool Library Journal\u003c\/i\u003e 06\/01\/2019 pg. 94\u003cbr\u003e\u003ci\u003eHornbook Guide to Children\u003c\/i\u003e 07\/01\/2019 - Recommended, Satisfactory","brand":"Mark Weston","offers":[{"title":"Hardcover","offer_id":44044552765695,"sku":"9780884485452","price":17.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_f74bfff9-7404-411e-89e1-4164e7d12ab0.jpg?v=1684973510","url":"https:\/\/www.whiterainbookhouse.com\/products\/finding-the-speed-of-light-mark-weston-9780884485452","provider":"WR Book House","version":"1.0","type":"link"}
