Astronomy Meghan Saha (1893-1959) was one of the foremost astrophysicists in our country. It is noteworthy that with the help of a formula he discovered, astronomers were able to determine the temperature, pressure, and many other aspects of the sun and stars. This formula may have caused a great revolution in astronomy.

Astronomy is the study of the spheres around the earth. It is a branch of physics. It seeks to learn about the origins, nature, and evolution of the solar system, stars, galaxies, and so on. Astronomers use telescopes mainly in their studies. These can be divided into optical and radio telescopes. “Optical telescopes” are used to see objects emitting visible light waves. The Visual Telescope named after the best astronomer “Vainupappu” set up at Kavalur in Tamil Nadu is the largest in Asia.

Astronomy is one of the oldest scientific disciplines known to man. India has produced many of the best astronomers in the world. BC 476 was the first researcher in the world to discover the following facts.

  • The earth is round
  • It rotates on its axis and orbits the sun.
  • That is why night and day are alternating.

He was the one who found that the most important level number in mathematics is “pi(r = 22/7) which is approximately 3.1416.

Brahma Gupta, who lived in 598 BC, was the first to introduce mathematics in astronomy.

Indian astronomers have made many discoveries in the study of planets and their motions. Attempts to calculate the orbits of the planets have greatly aided the development of mathematics. Thus the decimal system came into use. It is no exaggeration to say that this is fundamental to the overall scientific development.
