The Epicycle Model of Bhaskara





The Model propounded by Aryabhata is an algorithm. The Khmers drew the diagrams of the Sun by using the epicyle equivalent of the model developed by Bhaskara in the seventh century. Eccentricity is variable in this Epicycle Model.

Punjab and Bangalore prevail

We had 2 magnificent nerve baiting finishes yesterday. Dravid's men trouncing the Deccan Chargers by 3 runs and Punjab winning by 9 runs. The final over was bowled by experienced bowlers and they won the game for their teams. Kumble for Bangalore and Pathan for Punjab. If not for the great bowling of these bowlers, results could have been otherwise. This gives lie to the theory that T20 is a batter's game ! Piyush Chawla hit 21 in the last over to give Punjab a decent score, 178/6. Kolkota, despite David Hussy's 71 off 46 balls and Saha's 59 off 32, could only finish nine runs behind. Praveen Kumar took 3/23 and bowled the Royal Challengers to victory. 20 runs were need in the last over and Sanjay Bangar hit 2 sixes and almost did a Shane Warne. But Kumble's experience proved too much for the Deccan Chargers !

Ishant proved Gavaskar's word true, as he bowled India to an 11 runs lead ! His pace and bounce accounted for 6 West Indian scalps and he removed Edwards and Rampaul off successive balls, to bowl out West Indies for 190. Earleir, India could only get one wicket before the pre lunch session, that of Chanderpaul, who was clean bowled by Mithun for 37. Then Sharma came back strongly into the game and finished with the great figures of 21.5 - 7 - 55 - 6 ! Ishant was born with Mercury and Moon exalted, in Vasumath Yoga, a yoga for prosperity. His Sun is powerful in the 4th. His Rahu is dominant on the Meridien, which endows him with professional skill. His Mars in the Eleventh makes him a very competitive individual. Samuels was unconquered with 78 not out. He tried to redeem the West Indies, but Ishant was too smart for that ! The Indian openers played solidly in a tricky period and India are 23/0 ! Mihtun scalped two wickets for 34 and Praveen Kumar and Bajji took one wicket each. Man...
