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\u003eBinding Type:\u003c\/b\u003e Hardcover\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Tilbury House Publishers\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 03\/12\/2019\u003cbr\u003e\u003cb\u003eISBN:\u003c\/b\u003e 9780884485452\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 32\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\u003cstrong\u003eReview Citations: \u003c\/strong\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\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAccelerated Reader Quiz #\/Name: \u003c\/b\u003e504184 \/ Finding the Speed of Light: The 1676 Discovery That Dazzled the World\u003cbr\u003e\u003cb\u003eReading Level:\u003c\/b\u003e 5.1 \/ \u003cb\u003eInterest Level:\u003c\/b\u003e Middle Grade \/ \u003cb\u003ePoint Value:\u003c\/b\u003e 1\u003cbr\u003e","brand":"Mark Weston","offers":[{"title":"Default Title","offer_id":36645676908700,"sku":"9780884485452","price":15.26,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0473\/0804\/6492\/products\/img_6eb271df-0796-4ce4-84ce-8d538038f0cb.jpg?v=1603861783","url":"https:\/\/pastforward.org\/products\/finding-the-speed-of-light-the-1676-discovery-that-dazzled-the-world-9780884485452","provider":"Past Forward","version":"1.0","type":"link"}
