MOHAMMAD BIN MUSA AL-KHAWARIZMI (770 – 840 C.E.)

Abu Abdullah Mohammad Ibn Musa al-Khawarizmi was born at Khawarizm (Kheva), south of Aral sea. Very little is renowned about his early life, except for the detail that his parents had migrated to a location south of Baghdad. The exact designated days of his birth and death are furthermore not known, but it is established that he flourished under Al- Mamun at Baghdad through 813-833 and likely past away round 840 C.E.

Khawarizmi was a mathematician, astronomer and geographer. He was possibly one of the utmost mathematicians who ever dwelled, as, in fact, he was the founder of some parts and rudimentary concepts of mathematics. In the words of Phillip Hitti, he influenced mathematical thought to a larger span than any other mediaeval author. His work on algebra was spectacular, as he not only initiated the subject in a methodical form but he also evolved it to the span of giving analytical solutions of linear and quadratic formulas, which established him as the founder of Algebra. The very name Algebra has been derived from his well known book Al-Jabr wa-al-Muqabilah. His arithmetic synthesized Greek and Hindu information and furthermore comprised his own assistance of basic significance to numbers and science. therefore, he clarified the use of zero, a number of basic significance developed by the Arabs. likewise, he evolved the decimal system so that the overall scheme of numerals, ‘algorithm’ or ‘algorizm’ is named after him. In addition to inserting the Indian scheme of numbers (now usually renowned as Arabic numbers), he developed at extent some arithmetical procedures, including procedures on parts. It was through his work that the system of numerals was first presented to Arabs and later to Europe, through its translations in European dialects. He evolved in detail trigonometric benches containing the sine functions, which were probably extrapolated to tangent functions by Maslama. He furthermore finalised the geometric representation of conic parts and developed the calculus of two mistakes, which practically directed him to the notion of differentiation. He is also reported to have cooperated in the degree measurements organised by Mamun al-Rashid were directed at assessing of capacity and circumference of the soil.

The development of astronomical tables by him was a significant assistance to the science of astronomy, on which he furthermore wrote a publication. The assistance of Khawarizmi to geography is furthermore spectacular, in that not only did he modify Ptolemy’s outlooks on geography, but also amended them in minutia as well as his chart of the world. His other assistance include initial work related to timepieces, sun-dials and astrolabes.

some of his publications were translated into Latin in the early 12th years. In detail, his publication on arithmetic, Kitab al-Jam’a wal- Tafreeq bil Hisab al-Hindi, was lost in Arabic but endured in a Latin translation. His publication on algebra, Al-Maqala fi Hisab-al Jabr wa-al- Muqabilah, was furthermore converted into Latin in the 12th years, and it was this translation which presented this new science to the West “completely unknown till then”. He astronomical benches were furthermore converted into European languages and, later, into Chinese. His geography captioned Kitab Surat-al-Ard, simultaneously with its charts, was furthermore translated. In supplement, he composed a publication on the Jewish calendar Istikhraj Tarikh al-Yahud, and two publications on the astrolabe. He furthermore wrote Kitab al-Tarikh and his book on sun-dials was captioned Kitab al-Rukhmat, but both of them have been lost.

The leverage of Khawarizmi on the development of research, in general, and numbers, astronomy and geography in specific, is well established in history. Several of his publications were readily translated into a number of other dialects, and, in detail, constituted the university text-books till the 16th years. His approach was methodical and logical, and not only did he convey together the then current knowledge on diverse parts of science, particularly mathematics, but furthermore enriched it through his original assistance. No question he has been held in high repute all through the centuries since then.

Kratka pojašnjenja : "Islam je sastavljen od pet stvari: šehadeta i svjedočenja da nema drugog boga osim Allaha – la ilahe illalah, i da je Muhammed Allahov Poslanik – Muhammedun Resulullah, od klanjanja namaza, davanja zekata, obavljanja hadždža i posta mjeseca ramazana!". Klanjanje namaza, Namaz - molitva Allahu dž.š. Zekjat - 2.5% od imovine koja se ne koristi (zlato, novac, nekretnine) koju svaki Musliman izdvaja godišnje za pomoć siromašnima. Hadždž - vjerski obred koji vrši onaj ko može najmanje jednom u životu. Post - proces čuvanja tijela od grijeha, vode i hrane tokom mjeseca Ramazana. Ramazan - mjesec u Islamskom kalendaru u kome je početo objavljivanje Kur'an-a. Islamski kalendar se mjeri Mjesečevom-Lunarnom godinom. Hadis- predanje koje se prenosi od poslanika Muhameda s.a.w.s. Buhari, Muslim dva najpoznatija verodostojna sakupljača i objavljivača Hadisa. Za više pročitajte : šta je islam
