Aryabhatta, the ancient Indian genius, revolutionized mathematics and astronomy with concepts like pi, place value, and planetary motion that still shape science today.
When someone asks, “Who discovered zero?” most of us confidently say, Aryabhatta. And there’s a sense of pride in saying it, knowing he was of Indian origin.
But Aryabhatta’s contributions were not limited to just zero. His brilliance was first introduced to the world through his remarkable work in mathematics and astronomy. He was one of the earliest and most renowned Indian mathematicians. In fact, his ideas laid the foundation for the growth of both mathematics and astronomy, not just in India but across the world.
Early Life of Aryabhatta
Aryabhatta was born in 476 CE. Most scholars believe his birthplace was Kusumapura, which is present-day Patna in Bihar. Back in those days, Kusumapura was the capital city of Pataliputra during the Gupta Empire.
Some sources suggest he may have come from a region called Ashmaka. This could have been somewhere near modern-day Kerala or central India, between the Narmada and Godavari rivers.
Still, based on Aryabhatta’s own writings and what most researchers agree on, Kusumapura is considered his true hometown.
Not much is known about his early life. Details about his family or childhood were never clearly recorded. What we do know is that in his famous work, Aryabhatiya, he mentioned being 23 years old when he wrote it around 499 CE. This helps us figure out that he was born in 476 CE. While the rest of his early story remains unknown, his legacy speaks for itself.
Aryabhatta’s Education
Aryabhatta is believed to have studied in Kusumapura, which is now known as Patna in Bihar. Back then, it was a famous place for learning during the Gupta period. Many scholars and students came there to study subjects like science, maths, and astronomy.
Aryabhatta was likely a part of this learning environment. Some say he studied or even taught at the well-known Nalanda University, which was nearby. Nalanda also had an observatory, where people could study the stars and planets.
There’s also a belief that Aryabhatta led a school or institution in Kusumapura, helping teach others.
The atmosphere of learning in Kusumapura and Nalanda gave him access to a lot of knowledge. It helped him develop his ideas and make important contributions to mathematics and astronomy.
Notable Works by Aryabhatta
Aryabhatta wrote Aryabhatiya when he was just 23 years old. It’s his most well-known book and is made up of 121 short verses. These verses are divided into four main parts:
- Gitikapada : talks about the universe and large cycles of time
- Ganitapada: covers arithmetic, algebra, and geometry
- Kalakriyapada: explains how to measure time and track the movement of planets
- Golapada: describes the shape of the Earth, the sky, and how celestial bodies move
In this book, Aryabhatta introduced many ideas that were new to the world at the time. He explained the value of pi (about 3.1416), gave methods to find square and cube roots, and introduced the concept of the place value system, which is the basis of how we write numbers today. He also developed trigonometric tables and worked on sine functions, which are still taught in school math.
Arya-Siddhanta : Another Major Contribution
Though most of this book is now lost, Arya-Siddhanta was another one of his works that later scholars referred to. It helped in standardizing how astronomical calculations were done in ancient India.
Inspiration Behind Aryabhatta’s Work
Aryabhatta spent most of his life in Kusumapura, which is now known as Patna. At that time, it was a major hub of learning, filled with scholars, students, and intellectual exchange.
It’s believed that Aryabhatta not only studied there but may have also taught. He might have been connected to Nalanda University, one of the most respected educational institutions of that era.
The vibrant academic atmosphere of Kusumapura, along with exposure to a wide range of scientific ideas: from Vedic mathematics to global knowledge brought in through trade routes like the Silk Road, played a key role in shaping his thinking.
Some scholars also suggest that he was influenced by Greek and Babylonian astronomy.
Aryabhatta’s Ideas That Still Shape Science Today
Even though Aryabhatta lived more than 1,500 years ago, a lot of what he discovered still forms the base of how we learn and understand maths and astronomy today.
Contributions to Mathematics
Aryabhatta played a big role in developing the place value system.
It’s the method we still use to write numbers, where the position of each digit (like in tens, hundreds, or thousands) decides its value. While he didn’t use the zero symbol the way we do now, he used it as a placeholder, which was a major leap for arithmetic.
He also gave a very close value of pi, around 3.1416, which is still used to measure circles. Along with that, he introduced early ideas in trigonometry like sine and cosine. Today, these concepts are taught in schools and used in many fields including physics and engineering.
Aryabhatta also found smart ways to solve tricky algebra problems. His methods for solving quadratic and indeterminate equations, like the Kuttaka method, are still studied and used in maths and computer science.
Contributions to Astronomy
Aryabhatta was among the first to say that the Earth rotates on its axis, which is what causes day and night. At a time when most people believed the sky moved around the Earth, this idea was bold and ahead of its time.
He also explained solar and lunar eclipses using science, not myths. He even calculated the length of the solar year with surprising accuracy. Some of his ideas also point to the belief that planets move around the Sun, which we now know as the heliocentric model.
His work helped people move away from age-old beliefs and start looking at the universe through the lens of logic, maths, and careful observation.

Aryabhatta’s Global and Long-Lasting Legacy
Aryabhatta’s most well-known work, the Aryabhatiya, was later translated into Arabic. Through these translations, his ideas reached other parts of the world and influenced well-known Islamic scholars like Al-Biruni and Al-Khwarizmi. These scholars helped carry Aryabhatta’s knowledge even further, connecting ancient Indian science with global learning.
Even today, words like sine and cosine in trigonometry come from Sanskrit terms used by Aryabhatta. His ideas have become part of everyday mathematics without most of us even realizing it.
His work also played a big role in shaping traditional calendars. The Hindu calendar is based on some of his calculations, and his influence even reached the Jalali calendar, which is still used in parts of Central Asia.
How the World Remembers Aryabhatta
Aryabhatta’s legacy is still very much alive. In 1975, when India launched its very first satellite, it was proudly named Aryabhata to honor him. There’s also a university named after him: Aryabhatta Knowledge University in Bihar, where research in maths, science, and astronomy continues in his name.
But what truly makes Aryabhatta unforgettable is not just his discoveries, but his way of thinking. He questioned what others believed, trusted observation, applied logic, and let knowledge lead the way. That spirit of curiosity and reasoning is what science is all about, and it’s what continues to inspire people even today.
Aryabhatta was a brilliant Indian mathematician and astronomer born in 476 CE. He was one of the first to bring science and numbers together in a way that changed how we understand the world.
He’s best known for his book Aryabhatiya. In it, he shared ideas like the place value system, the value of pi, early trigonometry, and even gave scientific reasons for eclipses, things way ahead of his time.
Aryabhatta didn’t use the symbol ‘0’ as we know it today, but he did use zero as a placeholder in numbers. This was a huge step in how we write and calculate numbers now.
He was one of the first to say that the Earth spins on its axis, which causes day and night. He also explained solar and lunar eclipses using science and calculated the length of the year very accurately.
Aryabhatta’s legacy is still going strong. India named its first satellite after him, and his work is part of math and science lessons all over the world. His thinking still inspires learners and scientists today. 1. Who was Aryabhatta?
