**Heron of Alexandria** was a Greek Mathematician and Engineer who was born in Alexandria, Roman Egypt in c. 10 AD. He was famous for doing experiments. He spent his lifetime in Egypt learning, experimenting, and teaching Engineering and Mathematics. It is assumed that Hero used to teach at the Museum. He died in c. 70 AD.

## Contributions of Heron in Mathematics

Heron Contribution in the field of Mathematics:

- He described a method for iteratively computing the square root of a number.
- His work is now famously known as Heron’s formula. Using this formula one can find the area of a triangle from its side lengths.
- He also found a technique for calculating the square roots and cube roots.
- He also derived the shortest path algorithm.

## Other Mathematicians like Heron

Euclid and Thales of Miletus, Ptolemy were also Greek Mathematicians, who has contributed like Heron.

### What is S in Triangle?

Heron of Alexandria gave Heron’s formula to derive the area of a triangle using the three sides of the **triangle**, In simple terms, it can be described as the square root of the product **s**(**s** – a)(**s** – b)(**s** – c) where **s** is the semi perimeter of the **triangle**, that is, **s** = (a + b + c)/2.
