Interesting Indian Astronomer

Bhaskaracharya, or Bhaskara II, is regarded almost without question as the greatest Hindu mathematician of all time and his contribution to not just Indian, but world mathematics is undeniable. As L Gurjar states:

...Because of his work India gave a definite 'quota' to the forward world march of the science. [LG, P 104]

Born in 1114 AD (in Vijayapura, he belonged to Bijjada Bida) he became head of the Ujjain school of mathematical astronomy (Varahamihira and Brahmagupta had helped to found this school or at least 'build it up'). There is some confusion amongst the texts I have referred to as to the works that he wrote. C Srinivasiengar claims he wrote Siddhanta Siromani in 1150 AD, which contained four sections:

1) Lilavati (arithmetic)
2) Bijaganita (algebra)
3) Goladhyaya (sphere/celestial globe)
4) Grahaganita (mathematics of the planets)
