Most of you would have heard of Aryabhataan ancient astronomer and mathematician who lived between 476 and 550BC.

He was credited to have used the place value system which is based on the modern decimal system of calculation. In his work Aryabhatiyam  he has accurately conclude that  π  is an irrational number with an approximate value of 3.1416. In Ganitapada , Aryabhata gives the area of a triangle as “tribhujasya phalashariram samadalakoti bhujardhasamvargah” that translates to: “for a triangle, the result of a perpendicular with the half-side is the area.”. He also provided solutions to summation of a series.

His work on astronomy were ahead of his times. He concluded 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, contrary to the then-prevailing view, that the sky rotated.  He believed that the planet’s orbits as elliptical rather than circular. He invented  instruments for  astronomical  measurements  and observations

From ancient times the pole star or dhruva nakshatra was used by ancient mariners to locate directions. The star is approximately aligned with the earth’s axis of rotation. This  pole star usually refers to Polaris which is our maiden villa development in North Bangalore.
