Scholars or teachers having an immense deal of knowledge in mathematics and astronomy are known as” Mathematicians”.

Since many years we have been knowing about many of them who have shocked people with their extraordinary brain and mind facts. From creating the concept of zero to measuring the accurate days in a year, mathematicians in India have been debating the norms as well as a thirst for knowledge.

## **Some Indian mathematicians of India, known by their discoveries are:**

**Aryabhata**

**Aryabhata** was born in 476 CE in ** Pataliputra **(presently known as Patna), Bihar. He is famous for discovering and proving the concepts of the lunar eclipse and solar eclipse, rotation of Earth on its axis, the reflection of light by moon, the value of pi correct to 4 decimal places, the circumference of Earth to 99.8 per cent accuracy. His works include the famous ‘

**He wrote it when he was just 23 years old. He influenced other future mathematicians and thinkers as well -like Lalla, Bhaskara I, Brahmagupta, Varahamihira.**

*Aryabhatiya’.***Brahmagupta**

**Brahmagupta** was born in 598 CE in Ujjain. His fields include mathematics and astronomy. He was the first one to give rules for computation of zero. He wrote the book ‘** Brahmasphutasiddhanta’**. He was known for “zero’, “modern number system”, Brahmagupta’s theorem, etc. He died in 668 CE.

**Srinivasa Ramanujan**
