Did you know that long before Isaac Newton discovered the theory of gravity, there was a scientist who had thought of the theory.

He is a Muslim scientist who lived in the 12th century AD Historians pursue the title as' the greatest physician in history. ".

Muslim scientists who have contributed enormously to a modern development called Al Khazini. Al-Khazini was born in Byzantium or now known as Greece. Al Khazini is an all-round Muslim scientist who works in astronomy, physics, biology, chemistry, mathematics and philosophy.

Thanks to his intelligence, Al-Khazini succeeded in sparking important theories in fields such as: the experimental scientific method in mechanics; Potential strengths in; verse power, time and weight; also reporting distance. His hydrostatic balance theory has also encouraged the discovery of a variety of scientific equipment. One of the most important inherited al-Khazini in the field of astronomy is Table Sinjaric. The table describes a 24-hour clock designed for astronomical use. This is one of the first known astronomical clocks in the Islamic world.

In addition, al-Khazini also explained about the position of 46 stars which in the future became the reference of scientists and students in Kadu Byzantium. Al-Khazini also succeeded in creating a variety of tools that are essential for astronomical research and development such as triquetrum, dioptra, triangular, quadrant and sectional equipment, astrolabes and original equipment on reflection.

Another important contribution that al-Khazini inherited in the field of physics is the book Mizan al-Hikmah or Balance of Wisdom. In the book, al-Khazini explains in detail the thoughts and theories he created about the balance of hydrostatics, construction and usefulness, and the theory of statics or the science of equilibrium and hydrostatics.

Al-Khazini and other Muslim scientists also called hydrodynamics, he also has a growing knowledge in Europe. Not only that, Al-Khazini's thinking later inspired many important tools such as barometer and thermometer. Al-Khazin was also considered to be the inventor and size of the hot temperature, before it was later developed by Torriceli and Galileo.

Al-Khazini has also made a lot of capillarity measurements and uses aerometer for density and with respect to the temperature of liquids, the theory of levers and the use of measurements for buildings and for measuring time.
