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.
2) Bharadwaj

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

patanjali prescribed the control of prana (life breath) as the means to control the body, mind and soul. This subsequently rewards one with good health and inner happiness. Acharya Patanjali ‘s 84 yogic postures effectively enhance the efficiency of the respiratory, circulatory, nervous, digestive and endocrine systems and many other organs of the body. Yoga has eight limbs where Acharya Patanjali shows the attainment of the ultimate bliss of God in samadhi through the disciplines of: yam, niyam, asan, pranayam, pratyahar, dhyan and dharna.
10) Sushrut

Sushruta is an ancient Indian surgeon commonly attributed to as the author of the treatise Sushruta Samhita. He is dubbed as the “founding father of surgery” and the Sushrut Samhita is identified as one of the best and outstanding commentary on Medical Science of Surgery.

Sushruta in his book Sushruta Samhita discusses surgical techniques of making incisions, probing, extraction of foreign bodies, alkali and thermal cauterization, tooth extraction, excisions, and trocars for draining abscess, draining hydrocele and ascitic fluid, the removal of the prostate gland, urethral stricture dilatation, vesiculolithotomy, hernia surgery, caesarian section, management of haemorrhoids, fistulae, laparotomy and management of intestinal obstruction, perforated intestines, and accidental perforation of the abdomen with protrusion of omentum and the principles of fracture management, viz., traction, manipulation, appositions and stabilization including some measures of rehabilitation and fitting of prosthetics. It enumerates six types of dislocations, twelve varieties of fractures, and classification of the bones and their reaction to the injuries, and gives a classification of eye diseases including cataract surgery.
11) Varahmihir

Vedic mathematics were the first and foremost source of knowledge . Selflessly shared by ‪‎Hindus‬ to all around the ‪world‬. The Hindu FAQs Will now answer some discoveries around the world which may have existed in vedic hindusim. And as i always say, We wont judge, We will just write the article, its you who should know whether to accept it or reject it. We Need open mind to read this article. Read and learn about our unbelievable history . It will blow your mind ! ! !

But first, let me state Stigler’s law of eponymy:
“No scientific discovery is named after its original discoverer.”
Funny isn’t it.
Well It is also claimed that Babylonians knew and used the rule of the right triangle Long before Bauhayana and Pythagoras. It is also claimet to be developed sometime before Euclid, and it’s displayed very well in Euclid’s Elements. Some claime that it was chinese who discovered it before anyone else.

Well I wont go with who discovere it first, Rather i would explain Bauhayana’s Theory as our website is to know about hinduism, and not to prove how to hinduism is greatest of all.

So, Baudhayana, (800 BCE) was the author of the Baudhayana sutras, which cover dharma, daily ritual, mathematics, etc. He belongs to the Yajurveda school, and is older than the other sutra author Apastamba.
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.

Baudhanya
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.

Pythagorean Theorem
The square of the hypotenuse of a right-angled triangle equals to the sum of the square of the other two sides.

Baudhayana states:
“The area produced by the diagonal of a rectangle is equal to the sum of area produced by it on two sides.

Baudhayana listed Pythagoras theorem in his book called Baudhayana Sulbasutra (800 BCE). Incidentally, Baudhayana Sulbasûtra is also one of the oldest books on advanced Mathematics. The actual shloka (verse) in Baudhayana Sulbasutra that describes Pythagoras theorem is given below :

dirghasyaksanaya rajjuh parsvamani, tiryadam mani,
cha yatprthagbhute kurutastadubhayan karoti.

Interestingly, Baudhayana used a rope as an example in the above shloka which can be translated as – A rope stretched along the length of the diagonal produces an area which the vertical and horizontal sides make together. As you see, it becomes clear that this is perhaps the most intuitive way of understanding and visualizing Pythagoras theorem (and geometry in general) and Baudhāyana seems to have simplified the process of learning by encapsulating the mathematical result in a simple shloka in a layman’s language.
Baudhayana theorome
Some people might say that this is not really an actual mathematical proof of Pythagoras theorem though and it is possible that Pythagoras provided that missing proof. But if we look in the same Sulbasutra, we find that the proof of Pythagoras theorem has been provided by both Baudhayana and Apastamba in the Sulba Sutras! To elaborate, the shloka is to be translated as –
The diagonal of a rectangle produces by itself both (the areas) produced separately by its two sides.

Modern Pythagorean Theorem
The implications of the above statement are profound because it is directly translated into Pythagorean Theorem  and it becomes evident that Baudhayana proved Pythagoras theorem. Since most of the later proofs are geometrical in nature, the Sulba Sutra’s numerical proof was unfortunately ignored. Though, Baudhayana was not the only Indian mathematician to have provided Pythagorean triplets and proof.

Apastamba also provided the proof for Pythagoras theorem, which again is numerical in nature but again unfortunately this vital contribution has been ignored and Pythagoras was wrongly credited by Cicero and early Greek mathematicians for this theorem.

Baudhayana also presented geometrical proof using isosceles triangles so, to be more accurate, we attribute the geometrical proof to Baudhayana and numerical (using number theory and area computation) proof to Apastamba. Also, another ancient Indian mathematician called Bhaskara later provided a unique geometrical proof as well as numerical which is known for the fact that it’s truly generalized and works for all sorts of triangles and is not incongruent (not just isosceles as in some older proofs).

Circling the square

Another problem tackled by Baudhayana is that of finding a circle whose area is the same as that of a square (the reverse of squaring the circle). His sutra i.58 gives this construction:

Draw half its diagonal about the centre towards the East-West line; then describe a circle together with a third part of that which lies outside the square.

Square root of 2
Baudhayana i.61-2 (elaborated in Apastamba Sulbasūtra i.6) gives the length of the diagonal of a square in terms of its sides, which is equivalent to a formula for the square root of 2:

samasya dvikarani. pramanam trityena vardhayet
tac caturthenatmacatustrimsonena savisesah.

The diagonal [lit. “doubler”] of a square. The measure is to be increased by a third and by a fourth decreased by the 34th. That is its diagonal approximately.

The diagonal [lit. “doubler”] of a square. The measure is to be increased by a third and by a fourth decreased by the 34th. That is its diagonal approximately.

That is,

\sqrt{2} \approx 1 + \frac{1}{3} + \frac{1}{3 \cdot 4} - \frac{1}{3 \cdot4 \cdot 34} = \frac{577}{408} \approx 1.414216,

which is correct to five decimals.
