Gravity, not Newton’s theory
Hyderabad, Dec. 8: Long before the apple fell on Isaac Newton’s wise head, a Turkmenistani astro-nomer had penned the basic ideas of the theory of gravitation. To be exact, almost 450 years before Newton wondered how the earth pulled back things to itself, Abul Fatah Abdul Rahman Al Khazini had idea bulbs popping in his head, according to London-based Hyderabadi archivist Ziau-ddin Shakeb.
Shakeb said that two institutions in Hyderabad, Dairatul Ma’arif and Iqbal Academy, possessed one copy each of Al Khazini’s ancient treatise in which the astronomer-mathematician discussed the theory of gravitation. It is not known whether Newton had any idea of Al Khazini’s work. Quite probably, he discovered the phenomenon independently in 1687.
Shakeb, in an informal chat with a select group of people in the city recently, said that Al Khazini, who died in Turkmenistan in 1270 AD, stumbled upon the theory while he was writing his famous book Mez-anul Hikma or the Balance of Wis-dom. Al Khazini, while working on the book, began studying the movements of the sun, the moon and other planets. He studied the planets during solar and lunar eclipses and made mathematical calculations of the difference in their positions. He realised there was an invisible force working.
“Some of the elements of his speculations are in Mezanul Hik-ma,” said Shakeb. “But, I understand he wrote a paper exclusively on the subject of gravitational theory. I have not been able to trace it.” Al Khazini was a person of Greek origin who had been sold, while a child, as a slave to Abul Hussain Ali Bin Muhammad Al Khazin Al Marozi, the treasurer of the ruler. He brought him up as his own son and gave him the best education. The boy grew up to be a great scientist.
The archivist, who is consultant to auctioneer Christie’s on Indian and Islamic art, said that a few years ago the original manuscript of Mezanul Hikma reached London. It was bought by a private collector.
