al-KhwārizmiAbū Abdullah Muhammad ibn Mūsa al-Khwārizmi2910000Algorithmus780815mathematics, astronomyHindu numeralsWith Al-Kindi, introduced Hindu numerals to the Arab world (using characters representing 0-9, that can be arranged to show any number). Prior to the Hindu decimal system there were only two ways of working with numbers: the finger counting method and a complicated process of using Arabic letter characters. 161976The first record of numerals in the west are found in the Codex Vigilanus of 976. Pope Sylvester II tried to spread knowledge of numerals in Europe from the 980s, & Fibonacci promoted numerals in his Liber Abaci published 1202.directThe word algebra is derived from the title of his book, 'Kitab al-Jebr'. 850Possibly from Uzbekistan.

3), in the presence of steam. As saltpeter decomposes, it oxidizes the sulfur to SO
3, which combines with water to produce sulfuric acid. In 1736, Joshua Ward, a London pharmacist, used this method to begin the first large-scale production of sulfuric acid.
