His Majesty, Sultan Qaboos bin Said
sub section- Overview Stone Age 4000 BC 3000 BC 2000-1000 BC Dawn of Islam Oman's Rulers Al Bu Said Dynasty H.M. Sultan Qaboos
Sultan Qaboos bin Said was born in Salalah in Dhofar on 18th November, 1940, the only son of Sultan Said bin Taimur (1932-1970) and the eighth direct descendant of the royal Al Busaidi line, founded in 1744 by Imam Ahmed bin Said.
Sultan Qaboos has received his primary and secondary education in Salalah, and When he reached the age of 16, his father sent him to a private educational establishment in England. At the age of 20, he entered the Royal Military Academy at Sandhurst. After passing out of Sandhurst, he joined a British Infantry battalion on operations in Germany for one year and also held a staff appointment with the British Army.
After his military service, Sultan Qaboos studied local government subjects in England and, after a world tour, returned home to Salalah where he studied Islam and the history of his country. Upon his accession to the throne on 23 July 1970, he moved to Muscat where he declared that the country would no longer be known as 'Muscat and Oman', but would be united as the 'Sultanate of Oman'.
Since this time, Sultan Qaboos has faced many obstacles, not least than when he came to power. Oman today has an excellent health service, a clear road network and many educational establishments for girls and boys, from nursery levels, to university degrees.
His Majesty Sultan Qaboos has described his situation thus:"I am working for Oman - the country and its people...for me it is a delight to see my country and my people in the situation I imagined from the very first day I assumed power. I feel that I am a man with a mission rather than a man with authority.".

Life can give u ahundred resons
To cry , but u can give
Life a thousand reasons to smile
Good afternoon
As I promise you, I come back^^
The person that I choose is a famous man because he is the first man who discovers new things in mathematical such as: systematic solution of linear and quadratic equations.
MUHAMMAD BIN MUSA AL-KHWARIZMI
Abu Abdullah Muhammad Ibn Musa al-Khwarizmi was born at Khwarizm (Kheva), a town south of river Oxus in present Uzbekistan. (Uzbekistan, a Muslim country for over a thousand years, was taken over by the Russians in 1873.) His parents migrated to a place south of Baghdad when he was a child. The exact date of his birth is not known. It has been established from his contributions that he flourished under Khalifah (Calif) Al-Mamun at Baghdad during 813 to 833 C.E. and died around 840 C.E. He is best known for introducing the mathematical concept Algorithm, which is so named after his last name.
Al-Khwarizmi was one of the greatest mathematicians ever lived. He was the founder of several branches and basic concepts of mathematics. He is also famous as an astronomer and geographer. Al-Khwarizmi influenced mathematical thought to a
greater extent than any other medieval writer. He is recognized as the founder of Algebra, as he not only initiated the subject in a systematic form but also developed it to the extent of giving analytical solutions of linear and quadratic equations. The
name Algebra is derived from his famous book Al-Jabr wa-al-Muqabilah. He developed in detail trigonometric tables containing the sine functions, which were later extrapolated to tangent functions. Al-Khwarizmi also developed the calculus
of two errors, which led him to the concept of differentiation. He also refined the geometric representation of conic sections .The influence of Al-Khwarizmi on the growth of mathematics, astronomy and geography is well established in history. His
approach was systematic and logical, and not only did he bring together the then prevailing knowledge on various branches of science but also enriched it through his original contributions. He synthesized Greek and Hindu knowledge and also contained his own contribution of fundamental importance to mathematics and science. He adopted the use of zero, a numeral of fundamental importance, leading up to the so-called arithmetic of positions and the decimal system. His pioneering
work on the system of numerals is well known as "Algorithm," or "Algorizm." In addition to introducing the Arabic numerals, he developed several arithmetical procedures, including operations on fractions.
Finally, the contribution of Al-Khwarizmi to geography is also outstanding. He not only revised Ptolemy's views on geography, but also corrected them in detail. Seventy geographers worked under Khwarizmi's leadership and they produced the first map of the globe (known world) in 830 C.E. He is also reported to have collaborated in the degree measurements ordered by khalifah (Caliph) Mamun al-Rashid were aimed at measuring of volume and circumference of the earth. His geography book entitled "Kitab Surat-al-Ard," including maps, was also translated. His other contributions include original work related to clocks, sundials and astrolabes. He also wrote Kitab al-Tarikh and Kitab al-Rukhmat (on sundials).
