Acharya Pingala (piṅgala; around 3rd or 2nd century BCE) was an ancient Indian scholar. He wrote an important book called the Chandaḥśāstra, also known as Pingala-sutras. This book is the oldest known work about Sanskrit prosody.
Sanskrit prosody is the study of how poems and songs are put together in the ancient Indian language, Sanskrit. It looks at things like rhythm and patterns of syllables. Pingala's book has eight chapters. It was written in a style called Sūtra, which means it's very short and to the point. Later, in the 10th century, another scholar named Halayudha wrote a detailed explanation of Pingala's work.

Pingala's Amazing Math Ideas
Pingala's Chandaḥśāstra is not just about poetry. It also shows some very early and clever ideas in mathematics.
Binary Numbers and Syllables
Pingala's book describes a system similar to what we now call a binary numeral system. This is a way of counting using only two symbols, like 0 and 1. In computers, everything is stored using binary numbers.
Pingala used this idea to describe different patterns of syllables in poetry. Instead of 0s and 1s, he used "light" (laghu) and "heavy" (guru) syllables. A heavy syllable was equal to two light syllables. This system is a bit like Morse code, which uses dots and dashes to represent letters.
Zero and Ancient Math
Some people believe Pingala's work also hints at the idea of zero. He used the Sanskrit word śūnya, which means "empty" or "void," to refer to zero. This shows how advanced ancient Indian mathematics was.
Pascal's Triangle and Fibonacci Numbers
Pingala's work also connects to other famous math concepts:
- Pascal's Triangle: This is a triangular pattern of numbers where each number is the sum of the two numbers directly above it. It's used in many areas of math, like probability. In Halayudha's commentary on Pingala's book, this triangle is called meruprastāra.
- Fibonacci Numbers: These are a sequence of numbers where each number is the sum of the two preceding ones (like 0, 1, 1, 2, 3, 5, 8...). Pingala's work included ideas related to these numbers, which he called mātrāmeru.
Pingala's discoveries show that ancient Indian scholars were exploring complex mathematical ideas long ago.
