Algebra, alchemy, number, zenith, and zero: all words that come from the Arab Golden Age (8th–15th centuries) when the Muslim world was at the heart of scientific research, invention, and advance. This colorfully illustrated book for readers 8 to 12—named a Notable Book for Children by Smithsonian Magazine—traces the advent and expansion of Arab civilization though its scientific discoveries. In 9th-century Baghdad, al-Khwarizmi invented the decimal system, while Alhazen studied light in 10th-century Cairo and in Damascus, al-Shatir devoted himself to astronomy in the 14th century.
