He is best known for developing the concept of the algorithm in mathematics, and the word "algorithm" itself comes from a translation of his name, but he also made major contributions to the fields of algebra, trigonometry, astronomy, geography, and cartography. His systematic and logical approach to solving linear and quadratic equations gave shape to the discipline of algebra, a word that is derived from the name of his 830 book on the subject, Hisab aljabr w’almuqabala.
While his major contributions were the result of original research, he also did much to synthesize the existing knowledge in these fields from Greek, Indian, and other sources, stamping them with his unique mark of logic and rigor. He appropriated the placemarker symbol of zero, which originated in India, and he is also responsible for the use of Arabic numerals in mathematics that forever changed the way the world thinks about numbers.
AlKhwarizmi was familiar with Ptolemy's research in geography, which he systematized and corrected, using his own original findings. He supervised the work of 70 geographers to create the first map of the known world. When his work became known in Europe through Latin translations, his influence made an indelible mark on the development of science in the West: His algebra book introduced that discipline to Europe and became the standard mathematical text at European universities until the 16th century. He also wrote on mechanical devices like the clock, astrolabe, and sundial.
Mathematics and the sciences that are expressed in terms of mathematics would not be what they are today without the groundbreaking contributions of AlKhwarizmi.
