# 18 Facts Indians Don’t Know About Aryabhatta, The Master Astronomer & Mathematician

Aryabhatta was the first mathematician astronomer from the classical age of India, when mathematics and astronomy were still in their nascent stages of development around the globe. His works have been extensively used by the Greeks and others in the Middle East.

His most famous work was compiled when he was just 23 years old.

While we may all have heard about him, not many know interesting facts from his life. These are given below, and are a must read:

## 2. Aryabhatta composed numerous numerical and cosmic treatises; among these, ‘Aryabhatiya’ was his first major work.

He wrote his book ‘Aryabhatiya’, when he was only 23.

## 8. Aryabhatta has named the initial 10 decimal places and derived the methods for extracting square roots, summing arithmetic series and solving indeterminate equations of the type ax – by = c.

His method to find a solution to indeterminate equations of this type is recognized the world over.

## 10. He stated correctly the number of days in a year to be 365, alongside the seven-day week and about an intercalary month embedded into a year to make the calendar adjust to the seasons.

Time, therefore, could be measured all the more precisely.

## 13. Aryabhatta challenged many superstitious theories

He also gave a theory on eclipse; he said it wasn’t because of Rahu, as preached by many priests, but because of shadows cast by the earth and moon.

## 14. Aryabhatta pronounced that the moon has no light of its own.

It is visible because it mirrors the light of the sun.

## 17. In his old age, Aryabhatta composed another treatise, ‘Aryabhatta-siddhanta’.

It’s a booklet for every day astronomical calculations as well as a guide to examine auspicious times for performing rituals.To this very day, astronomical data provided in this text is used for preparing panchangs (Hindu calendars).

## 18. India’s first satellite Aryabhatta was named after him.

There is also an Indian research center is called ‘Aryabhata Research Institute of Observational Sciences’.

We hope more Indians would come to know about this master astronomer and mathematician. We really should be proud that we had such a man making such advanced discoveries back in the day when half of the world wasn’t even civilized.
