Indians knew about gravity before Newton: Isro ex-chief

Retarded.. Hmmmm .. Okay ... Enjoy your ancient nuclear wars,inter space travelling space ships with reverse heard,genetically n molecular engineering,ancient plastic surgery - replacing a boy's head with an elephants, n now this ...:tup:



N sorry you guys forgot all that ... I deeply am ..:(
I think your education system did not teach you about Great Indians like :-
Aryabhatta :-Aryabhata is the author of several treatises on mathematics and astronomy, some of which are lost.

His major work, Aryabhatiya, a compendium of mathematics and astronomy, was extensively referred to in the Indian mathematical literature and has survived to modern times. The mathematical part of the Aryabhatiya covers arithmetic, algebra, plane trigonometry, and spherical trigonometry. It also contains continued fractions, quadratic equations, sums-of-power series, and a table of sines.

The Arya-siddhanta, a lost work on astronomical computations, is known through the writings of Aryabhata's contemporary,Varahamihira, and later mathematicians and commentators, including Brahmagupta and Bhaskara I. This work appears to be based on the older Surya Siddhanta and uses the midnight-day reckoning, as opposed to sunrise in Aryabhatiya. It also contained a description of several astronomical instruments: the gnomon (shanku-yantra), a shadow instrument (chhAyA-yantra), possibly angle-measuring devices, semicircular and circular (dhanur-yantra / chakra-yantra), a cylindrical stick yasti-yantra, an umbrella-shaped device called the chhatra-yantra, and water clocks of at least two types, bow-shaped and cylindrical.

You are confusing the two Bhaskaras. The fellow who wrote the Chedyakadhikara was Bhaskara 2, who lived in the 12th century. He revered Brahmagupta, and in fact most of his works build on earlier works of Brahmagupta. Bhaskara 1 was roughly contemporanious with Brahmagupta.

There is no confusion.

The first model of heliocentric model of planetary motion was recorded by Aryabhata somewhere in 400 AD (425 AD to be precise), i.e. almost 2000 years back. He was the first to insist that the earth rotates about its axis daily, and that the apparent movement of the stars is a relative motion caused by the rotation of the earth.

PitamahaSiddhanta provides a chart of the planetary motion for the Moon, Mercury, Venus, Mars, Jupiter and Saturn. The only flaw in his model was that it was earth centric.

It was Varahamihira (505 AD to 587 AD) who first explained Gravity and provided a chart that maps planetary movement. He called that force of attraction (now know as Gravity) as Gurutvakarshan. i.e. the Force of attraction towards the Master.

Bhaskarcharya or Bhaskara 2 further expanded on the work of Aryabhata and varahamihira considerably. He help define the planetary motion and attributed that to Guruvakarshan or Gravity.

The Mathematical approach to Astronomy and Gravity was first used in India as can be seen.

To those who are not aware who this man is, he was someone behind the success of Chandrayan-1 mission India had sent and for Chandrayaan, the equation of Aryabhatta was used. Goes on to prove enough that we are right with our history.
