Aryabhata was the first in the line of great mathematician-astronomers from the classical age of Indian mathematics and Indian astronomy. He is the author of several treatises on mathematics and astronomy.
His major work, Aryabhatiya, a compendium of mathematics and astronomy, was extensively referred to in the Indian mathematical literature and has survived to modern times. The mathematical part of the Aryabhatiya covers arithmetic, algebra, plane trigonometry, and spherical trigonometry. It also contains continued fractions, quadratic equations, sums-of-power series, and a table of sines.
He formulated the process of calculating the motion of planets and the time of eclipses.

Baudhayana was the author of the Baudhayana sutras, which cover dharma, daily ritual, mathematics, etc.

He was the author of the earliest Sulba Sutra—appendices to the Vedas giving rules for the construction of altars—called the Baudhayana Sulbasutra. These are notable from the point of view of mathematics, for containing several important mathematical results, including giving a value of pi to some degree of precision, and stating a version of what is now known as the Pythagorean theorem.

Sequences associated with primitive Pythagorean triples have been named Baudhayana sequences. These sequences have been used in cryptography as random sequences and for the generation of keys.

Bhaskaracharya was an Indian mathematician and astronomer. his works represent a significant contribution to mathematical and astronomical knowledge in the 12th century.  His main work Siddhanta Shiromani deal with arithmetic, algebra, mathematics of the planets, and spheres respectively.
Bhaskaracharya’s work on calculus predates Newton and Leibniz by over half a millennium. He is particularly known in the discovery of the principles of differential calculus and its application to astronomical problems and computations. While Newton and Leibniz have been credited with differential and integral calculus, there is strong evidence to suggest that Bhaskaracharya was a pioneer in some of the principles of differential calculus. He was perhaps the first to conceive the differential coefficient and differential calculus.

Acharya Charak has been crowned as the Father of Medicine. His renowned work, the ” Charak Samhita “, is considered as an encyclopedia of Ayurveda. His principles, diagoneses, and cures retain their potency and truth even after a couple of millennia. When the science of anatomy was confused with different theories in Europe , Acharya Charak revealed through his innate genius and enquiries the facts on human anatomy, embryology, pharmacology, blood circulation and diseases like diabetes, tuberculosis, heart disease, etc. In the ” Charak Samhita ” he has described the medicinal qualities and functions of 100,000 herbal plants. He has emphasized the influence of diet and activity on mind and body. He has proved the correlation of spirituality and physical health contributed greatly to diagnostic and curative sciences. He has also prescribed and ethical charter for medical practitioners two centuries prior to the Hippocratic oath. Through his genius and intuition, Acharya Charak made landmark contributions to Ayurvedal. He forever remains etched in the annals of history as one of the greatest and noblest of rishi-scientists.
6) Kanad

Kanada was a Hindu sage and philosopher who founded the philosophical school of Vaisheshika and authored the text Vaisheshika Sutra.

His primary area of study was Rasavadam, considered to be a type of alchemy. He is said to have believed that all living beings are composed of five elements: water, fire, earth, air, Aether (classical element). Vegetables have only water, insects have water and fire, birds have water, fire, earth and air, and Humans, the top of the creation, have ether—the sense of discrimination (time, space, mind) are one.

He says, “Every object of creation is made of atoms which in turn connect with each other to form molecules.” His statement ushered in the Atomic Theory for the first time ever in the world. Kanad has also described the dimension and motion of atoms and their chemical reactions with each other.
7) Kapil

He gifted the world with the Sankhya School of Thought. His pioneering work threw light on the nature and principles of the ultimate Soul (Purusha), primal matter (Prakruti) and creation. His concept of transformation of energy and profound commentaries on atma, non-atma and the subtle elements of the cosmos places him in an elite class of master achievers – incomparable to the discoveries of other cosmologists. On his assertion that Prakruti, with the inspiration of Purusha, is the mother of cosmic creation and all energies, he contributed a new chapter in the science of cosmology.
8) Nagarjuna

The Sundial at Konark Sun temple in India built in 1250 A.D is a treasure trove of secrets of ancient India. People still use it today to tell time. We know how the sundial works and shows time accurate to the minute. What is interesting is what is missing from the picture!
konark Sun temple
For the uninitiated the sundial has 8 major spokes that divide 24 hours into 8 equal parts, which means that the time between two major spokes is 3 hours.

8 Major spokes. Distance between 2 spokes is 3 hours.

There are 8 minor spokes as well. Each minor spoke runs exactly in the middle of 2 major spokes. This means that the minor spoke divides the 3 hours in half, so the time between a major spoke and a minor spoke is an hour and half or 90 minutes.

8 Minor spokes between 2 major spokes dividing 3 hours, i.e. 180 minutes into 90 minutes each

The edge of the wheel has a lot of beads. There are 30 beads between a minor and a major spoke. So, the 90 minutes are further divided by 30 beads. This means that each bead carries a value of 3 minutes.

The beads are large enough, so you can also see if the shadow falls in the center of the bead or on one of the ends of the bead. This way we can further calculate time accurately to the minute.

Imagine how much time and coordination would have happened between the astronomers, engineers and sculptors to create something like this, 750 years ago.

There are 2 questions that one would get in their mind. The first question would be, what happens when the sun moves from east to west. Since the wheel is carved on a wall, the sun would not shine on this wheel at all. How can we tell time in the afternoons? Now, the Konark sun temple has another wheel or sundial, located on the west side of the temple as well. You can just use the other sundial that will work perfectly from afternoon, until sunset.

The second and the most interesting question about the Konark sun temple. How do you tell time after sunset? There would be no sun, and hence no shadows from sunset till the next morning’s sunrise. After all, we have 2 sundials in the temple which work only when the sun shines. Well, actually, the Konark sun temple does not have just 2 wheels like this. The temple has a total of 24 wheels, all accurately carved just like the sundials. Have you heard of the Moondial? Do you know that the moondials can work just like sun dials during night time? What if the other wheels in the temple could be used as moondials?

Many people think that the other 22 wheels were carved for decorative or religious purposes and do not have an actual use. This is what people thought about the 2 sundials as well. Believe it or not, people thought that all the 24 wheels were just carved for beauty and as Hindu symbols. About 100 years ago, it became known that this was a sundial when an old yogi was seen calculating time secretly. Apparently selected people were using these wheels for generations and for 650 years no one else knew about it. They say that when they asked him about the purpose of the other 22 wheels, the yogi refused to talk and simply walked away.

And our knowledge of just these 2 sundials themselves is actually very limited. There are multiple circles of beads. There are carvings and markings all over these sundials, and we don’t know the meaning of most of them. For example, this carving on a major spoke has exactly 60 beads. Some carving you can see leaves and flowers which may mean Spring or Summer. Some carvings you can see monkeys mating, which only happens during winter. So, these sundials could have even been used as an almanac for a variety of different things. Now you can understand how limited our knowledge is about the rest of the 22 wheels.

There are clues on these wheels that people have overlooked for centuries. Notice how a woman wakes up and looks at a mirror in the morning. Notice how she is stretching, being tired and ready to go to sleep. And you can also see that she is engaging in sexual activity during night. For centuries, people have ignored these hints and thought that these were carvings of Hindu Goddesses.

This is also a perfect example of how people think ancient unexplained carvings are just for beauty or religious purposes. If ancient people spent a lot of time creating something, there is a very good chance that it was done for a valuable, scientific purpose.
