Greetings and very good morning to everyone present. Today on this auspicious day I am going to speak about the father of Indian Mathematics Aryabhatta. The earliest mathematician and astronomer in India was Aryabhatta. Aryabhatta’s greatest contribution was in the area of mathematics. He discovered a number of trigonometric functions that are extremely important in contemporary mathematics. The difficulties in mathematics are eliminated by Aryabhatta’s discovery of the value of “pi.” But his discovery of place value and zero is the mathematical equivalent of a stroke of genius. The book “Aryabhatiya” has a variety of astronomical theories.

Aryabhatta excelled at mathematics and has extensive astronomical knowledge. His heliocentric theory states that the planets rotate around the sun. He used his hypothesis to determine the relative speeds of the planets to the Sun. The sidereal year, which stipulates that there should be 365 days, 6 hours, 12 minutes, and 30 seconds in a year, was one of his most important astronomical discoveries. This differs just by 3 minutes and 20 seconds from the current number.

The world revolves on its axis, as was properly established by Aryabhatta. He also anticipated the geocentric solar system model, which put the earth at the center of the universe. The sun, moon, and planets rotate around it. He also discussed lunar and solar eclipses in his book. His book provided an explanation of how the earth and moon’s shadows cause solar eclipses and lunar eclipses to occur.
