{"product_id":"al-karaji-susan-nichols-9781508171430","title":"Al-Karaji: Tenth-Century Mathematician and Engineer","description":"Tenth-century mathematician al-Karaji is best known for his writings on algebra and for freeing algebra from geometry. The scholar spent most of his life in Baghdad, where he established a school for algebra and served as a vizier for the Abbasid government. Al-Karaji also was an accomplished engineer who wrote extensively on water extraction. Many of his hydrological ideas are still used in the Middle East today. While some modern scholars question his originality, others maintain he was an important transition between ancient mathematics and modern algebra.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Susan Nichols\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 1508171432\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9781508171430\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Rosen Young Adult\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 07\/30\/2016\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 112\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Library Binding\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.75lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.10h x 6.10w x 0.50d","brand":"Susan Nichols","offers":[{"title":"Library Binding","offer_id":48453734924543,"sku":"9781508171430","price":38.8,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_38578886-58ef-41c2-a869-5e0d5af1247a.jpg?v=1777301987","url":"https:\/\/www.whiterainbookhouse.com\/products\/al-karaji-susan-nichols-9781508171430","provider":"WR Book House","version":"1.0","type":"link"}
