• Aryabhatta : Among the notable scholars was Aryabhata, whose work in the 5th century CE revolutionized astronomy. He proposed the concept of a heliocentric solar system, with the Earth rotating on its axis and orbiting the sun. Aryabhata accurately calculated the Earth's circumference and explained the causes of eclipses. His groundbreaking book, the "Aryabhatiya," laid the groundwork for future astronomical studies.
• Brahmagupta : Brahmagupta, another influential astronomer and mathematician, made significant strides in understanding planetary motions and proposed mathematical formulas to calculate their positions. He introduced the concept of zero and negative numbers, revolutionizing the field of mathematics. Brahmagupta's work, particularly his treatise called "Brahmasphutasiddhanta," provided valuable insights into celestial phenomena and mathematical principles.
• Varahamihira : Varahamihira, considered one of the greatest astronomers of ancient India, contributed to the understanding of planetary movements and celestial mechanics. His renowned work, the "Brihat Samhita," covered various topics such as astrology, mathematics, architecture, and meteorology. Varahamihira's accurate calculations and predictions of celestial events made a lasting impact on the field of astronomy.
• Medical Science in Ancient India : Medical science was greatly advanced in line with the times. The traditional medical practice known as Ayurveda was created in ancient India. The literal meaning of the word "Ayurveda" is "the science of longevity and good health." This traditional Indian medical approach aids in not only treating illnesses but also identifying their causes and symptoms. It serves as a manual for both healthy and ill people. It characterizes both health and sickness as an equilibrium between the three doshas (vata, pitta, kapha). When using herbal remedies to cure a condition, the goal is to attack the ailment's fundamental causes to eradicate them. Health and longevity have been the primary goals of Ayurveda.

It is the world's most ancient system of medicine. The Atreya Samhita, a treatise on Ayurveda, is the world's oldest medical text. Susruta is known as the father of surgery, whereas Charak is credited as the creator of Ayurvedic medicine. The well-known ayurvedic doctors Susruta, Charak, Madhava, Vagbhatta, and Jeevak were among them. Do you realize how popular Ayurveda has recently become in the west? This is due to its many advantages over the contemporary, western-based Allopathy method of medicine.

• Sushruta : Susruta made significant contributions to surgery. The highest branch of the healing arts and the one least susceptible to error, in his opinion, was surgery. He used a dead body as a study tool for human anatomy. Over 1100 illnesses are recorded in Susruta Samhita, including 26 different types of fevers, 8 different types of jaundice, and 20 different types of urinary problems. The process of choosing and keeping a dead body for the sake of its in-depth study has also been covered in the Susruta Samhita. The fields of rhinoplasty (plastic surgery) and ophthalmic surgery (cataract removal) were those in which Susruta made the most significant contributions. Cutting one's nose and/or ears was a typical punishment back then. The recovery of these or other limbs was a wonderful blessing.
• Charak : The early Indian science of medicine is credited to Charak. He served as the royal physician (Raj Vaidya) for Kanishka. His Charak Samhita is a noteworthy medical text. It includes descriptions of numerous disorders as well as instructions on how to determine their causes and cure them. He was the first to discuss immunity, metabolism, and digestion as being crucial to health and medical science. Instead of just treating the symptoms of illness, the Charak Samhita places more emphasis on eradicating the root of the problem. Charak was also familiar with the basics of genetics.
• Yoga and Patanjali : Yoga is a branch of Ayurveda that was created in ancient India to treat physical and mental ailments without the use of drugs. Its roots are in the Vedas, just like all other sciences. It defines chitta as the condition of equilibrium attained once a person's consciousness has dissipated all their thoughts, feelings, and wants. Yoga combines mental and physical practice. Hathyoga, a type of physical yoga, attempts to cure a sickness and bring the body back to health. Mental yoga is Rajayoga. Its objective is to achieve physical, mental, emotional, and spiritual equilibrium to realize oneself and be freed from captivity. Yoga was transmitted orally from one sage to another, but sage Patanjali deserves praise for organizing this important science in a systematic way and presenting it to the world.

From 1200 BCE onward, Indian mathematics first appeared in the Indian subcontinent. Up to the 18th century's conclusion, this continued. Scholars like Aryabhatta, Brahmagupta, and Bhaskara II made significant contributions to Indian mathematics during the classical era (400 AD to 1200 AD).

The first mention of the current decimal number system is found in Indian mathematics. Early mathematicians from India contributed greatly. These contributions dealt with negative numbers, arithmetic, algebra, and the idea of zero as a number.

Ancient Mathematics

Trigonometry was developed further in India, specifically the contemporary definitions of sine and cosine that were created here, along with algebra, arithmetic, and negative numbers. The Middle East, China, and Europe all received these mathematical ideas, which sparked subsequent research that eventually became the cornerstones of numerous branches of mathematics. Indian mathematics from antiquity and the Middle Ages were all written in Sanskrit. It often consisted of a sutra section where a series of guidelines or issues were laid forth.

To make the sutras easier for a learner to memorize, they were stated in an extremely concise manner. A prose commentary that described the issue in more detail and supported the solution was presented after this in the second section. The prose section's form was not given as much weight as the concepts it contained. Up until roughly 500 BCE, all mathematical works were communicated verbally. Following that, they were communicated verbally and in written form. The Bakhshali Manuscript, written on birch bark, is the oldest surviving example of a mathematical work created on the Indian subcontinent. It was found in 1881 in the Pakistani town of Bakhshali, close to Peshawar. It was thought that this manuscript dated to the seventh century CE.
