**Euclid of Alexandria** was a Greek Mathematician. He was born in 323 BC. He is also known as “founder/father of geometry”. Most of his days was spent in Alexandria. During his lifetime, he has written 13 books which are now famous as Euclid Elements. His books are one of the most influential works in the history of mathematics. These books will improve the Mental Mathematics.

This book is considered as a textbook for teaching mathematics. In the *Elements*, Euclid derived a theorem which is now known as Euclidean geometry. He also wrote works on spherical geometry, conic sections, number theory, perspective, and mathematical rigor.

He died in 283 BC. This was one of the most saddest part in the history of mathematicians at that moment of time.

## Contributions of Euclid in Mathematics

Euclid has written more than 13 books, which deals with the various topics of mathematics like geometry. His books are said to be most read mathematics books in schools and colleges.

**List of his books:**

- Books 1-6 covers the topics of plane geometry,
- Books 7-9 covers the topics of number theory,
- Book 10 covers the topics of Eudoxus’s theory of irrational numbers, and
- Books 11-13 covers the topics of a solid geometry.

He has derived the **Euclid–Euler theorem** which is named after Euclid and Leonhard Euler. This theorem says that any number will be considered as even number is perfect if and only if it has the form 2*p*−1(2*p* − 1), where 2*p* − 1 is a prime number. The theorem is named after Euclid.

## Interesting facts about Euclid

- It is said that he used to follow the orders of Alexander the Great. Under his guidelines of Alexander the Great, and with the help of Euclid, the great new city of academia and commerce was constructed in Egypt.
- His books are said to be ” the most studied books apart from the Bible”.

## Awards and Rewards under the name of Euclid

## Quotes By Euclid

“A straight line is said to have been cut in extreme and mean ratio when, as the whole line is to the greater segment, so is the greater to the lesser.”

“A ‘unit’ is that by virtue of which each of the things that exist is called one.”

” A ‘number’ is a multiple composed of units”

“What has been affirmed without proof can also be denied without proof.”

“The laws of nature are but the mathematical thoughts of God.”

“There is no Royal Road to Geometry.”

## Mathematicians like Euclid

Just Like Euclid, Shakuntala Devi used to apply the same pedagogy in mathematics. Shakuntala Devi has also written many books like him which tells a lot about mathematics.

There are other notable mathematicians from his birthplace like Thales of Miletus, Hero of Alexandria who did a lot of things in mathematics.
