[edit] Astronomy

Main article: Indian astronomy
Further information: Hindu cosmology and Jyotisha

Ancient India’s contributions to astronomy are well known and documented. The earliest references to astronomy, referring to around 4500 BCE, are found in the Rig Veda. By 500 CE, ancient Indian astronomy emerged as an important part of Indian studies and its affect is seen in several treatises of that period. In some instances, astronomical principles were borrowed to explain matters pertaining to astrology (called Jyotisha in India), like the casting of a horoscope. Apart from this link of astronomy to astrology in ancient India, the science of astronomy continued to develop independently and culminated in original findings such as: The astronomy and the astrology of Ancient India (Jyotisha) is based upon sidereal calculations. ... // an egg broke and out came the planets thanks to gods pet hen The Rig Veda describes the origin of the universe as: Then was not non-existence nor existence: there was no realm of air, no sky beyond it. ...

[edit] Vedic astronomy

There are astronomical references of chronological significance in the Vedas. Some Vedic notices mark the beginning of the year and that of the vernal equinox in Orion; this was the case around 4500 BCE. Fire altars, with astronomical basis, have been found in the third millennium cities of India. The texts that describe their designs are conservatively dated to the first millennium BCE, but their contents appear to be much older.

Lagadha (लगध) is the author of Vedanga Jyotisha, the text on Vedic astronomy that has been dated to 1350 BC. This text describes rules for tracking the motions of the sun and the moon. ...


The earliest concept of a heliocentric model of the solar system, in which the Sun that is at the centre of the solar system and the Earth that is orbiting it, is found in several Vedic Sanskrit texts written in ancient India. Heliocentric Solar System Heliocentrism (lower panel) in comparison to the geocentric model (upper panel) In astronomy, heliocentrism is the idea that the sun is at the center of the Universe and/or the Solar System. ...

The History of India begins with the Indus Valley Civilization, which flourished in the north-western part of the Indian subcontinent from 3300 to 1700 BC. This Bronze Age civilization was followed by the Iron Age Vedic period, which witnessed the rise of major kingdoms known as the Mahajanapadas. ...


The Aitareya Brahmana (2.7) (c. 9th–8th century BCE) states: "The Sun never sets nor rises. When people think the sun is setting, it is not so; they are mistaken." This indicates that the Sun is stationary (hence the Earth is moving around it), which is elaborated in a later commentary Vishnu Purana (2.8) (c. 1st century), which states: "The sun is stationed for all time, in the middle of the day. [...] Of the sun, which is always in one and the same place, there is neither setting nor rising." The Aitareya Brahmana is the Brahmana associated with the Rigveda in the Shakala school. ... The Vishnu Purana is one of the oldest of the Puranas (dating to maybe the 5th century), containing some 23,000 shlokas, presented as a dialogue between Parasara with his disciple Maitreya. ... The 1st century was that century which lasted from 1 to 100 according the Gregorian calendar. ...


Yajnavalkya (c. 3rd millennium BCE) recognized that the Earth was round and believed that the Sun was "the centre of the spheres" as described in the Vedas at the time. His astronomical text Shatapatha Brahmana (8.7.3.10) stated: "The sun strings these worlds - the earth, the planets, the atmosphere - to himself on a thread." He recognized that the Sun was much larger than the Earth, which would have influenced this early heliocentric concept. He also accurately measured the relative distances of the Sun and the Moon from the Earth as 108 times the diameters of these heavenly bodies, almost close to the modern measurements of 107.6 for the Sun and 110.6 for the Moon. Sage Yajnavalkya (याज्ञवल्क्य) of Mithila advanced a 95-year cycle to synchronize the motions of the sun and the moon. ...

The Vedas (Sanskrit: वेद) are a large corpus of texts originating in Ancient India. ... Shatapatha Brahmana (Brahmana of one-hundred paths) is one of the prose texts describing the Vedic ritual. ...


Based on his heliocentric model, Yajnavalkya proposed a 95-year cycle to synchronize the motions of the Sun and the Moon, which gives the average length of the tropical year as 365.24675 days, which is only six minutes longer than the modern value of 365.24220 days. This estimate for the length of the tropical year remained the most accurate anywhere in the world for over a thousand years. A tropical year is the length of time that the Sun, as viewed from the Earth, takes to return to the same position along the ecliptic (its path among the stars on the celestial sphere). ... A tropical year is the length of time that the Sun, as viewed from the Earth, takes to return to the same position along the ecliptic (its path among the stars on the celestial sphere). ...


There is an old Sanskrit shloka (couplet) which also states "Sarva Dishanaam, Suryaha, Suryaha, Suryaha"[citation needed] which means that there are suns in all directions. This couplet which describes the night sky as full of suns, indicates that in ancient times Indian astronomers had arrived at the important discovery that the stars visible at night are similar to the Sun visible during day time. In other words, it was recognized that the sun is also a star, though the nearest one. This understanding is demonstrated in another Sloka which says that when one sun sinks below the horizon, a thousand suns take its place. The Sanskrit language ( , for short ) is a classical language of India, a liturgical language of Hinduism, Buddhism, Sikhism, and Jainism, and one of the 23 official languages of India. ... Wikipedia does not yet have an article with this exact name. ...


[edit] Classical astronomy

Many Indian astronomers had later formulated ideas about gravity and gravitation in the early Middle Ages. The Middle Ages formed the middle period in a traditional schematic division of European history into three ages: the classical civilization of Antiquity, the Middle Ages, and modern times, beginning with the Renaissance. ...


The cosmological time cycles explained in the Surya Siddhanta, which was copied from an earlier work, gives: This article aims at providing a thorough (but not verse by verse) exposition of most important topics of and problems related to Surya Siddhanta and its comparison with ancient and modern astronomy, together with its use in astrology. ...

  • The average length of the sidereal year (the length of the Earth's revolution around the Sun) as 365.2563627 days, which is only 1.4 seconds longer than the modern value of 365.2563627 days. This remained the most accurate estimate for the length of the sidereal year anywhere in the world for over a thousand years.
  • The average length of the tropical year (the length of the year as observed on Earth) as 365.2421756 days, which is only 2 seconds shorter than the modern value of 365.2421988 days. This estimate remained the most accurate estimate for the length of the tropical year anywhere in the world for another 6 centuries (until Islamic mathematics Omar Khayyam gave a better estimate), and still remains more accurate than the value given by the modern Gregorian calendar currently in use around the world, which gives the average length of the year as 365.2425 days.

Later Indian astronomer-mathematicians such as Aryabhata made references to this text, while later Arabic and Latin translations were very influential in Europe and the Middle East. The sidereal year is the time for the Sun to return to the same position in respect to the stars of the celestial sphere. ...

The Indian astronomer-mathematician Aryabhata (476550), in his magnum opus Aryabhatiya, propounded a mathematical heliocentric model in which the Earth was taken to be spinning on its axis and the periods of the planets were given with respect to a stationary Sun. The treatise also uses a geocentric model of the solar system, in which the Sun and Moon are each carried by epicycles which in turn revolve around the Earth. He also theorized that the light from the Moon and the planets were reflected from the Sun. He also accurately calculated many astronomical constants, such as the times of the solar and lunar eclipses, and the instantaneous motion of the Moon (expressed as a differential equation). Arabic translations of Aryabhata's Aryabhatiya were available from the 8th century, while Latin translations were available from the 13th century, before Copernicus had written De revolutionibus orbium coelestium, so it's possible that Aryabhata's work had an influence on Copernicus' ideas.

Aryabhata wrote that 1,582,237,500 rotations of the Earth equal 57,753,336 lunar orbits. This is an extremely accurate ratio of a fundamental astronomical ratio (1,582,237,500/57,753,336 = 27.3964693572), and is perhaps the oldest astronomical constant calculated to such accuracy.


Brahmagupta (598-668 CE) was the head of the astronomical observatory at Ujjain and during his tenure there wrote a text on astronomy, the Brahmasphutasiddhanta in 628 CE.

Bhaskara (1114-1185), the head of the astronomical observatory at Ujjain, continued the mathematical tradition of Brahmagupta. He wrote the Siddhanta-Shiromani which consists of two parts: Goladhyaya (sphere) and Grahaganita (mathematics of the planets). He also expanded on Aryabhata's heliocentric model in his treatise Siddhanta-Shiromani, where he mentioned the law of gravity, discovered that the planets don't orbit the Sun at a uniform velocity, and accurately calculated many astronomical constants based on this model, such as the solar and lunar eclipses, and the velocities and instantaneous motions of the planets. Bhaskara (1114-1185), also known as Bhaskara II and Bhaskara Achārya (Bhaskara the teacher), was an Indian mathematician-astronomer. ...

Linguistics (along with phonology, morphology, etc.) first arose among Indian grammarians who were attempting to catalog and codify Sanskrit's rules.

Linguistics was pursued in ancient India for many centuries. The Sanskrit grammar of Pāṇini (c. 520460 BCE), who is often considered the founder of linguistics, contains a particularly detailed description of Sanskrit morphology, phonology and roots, evincing a high level of linguistic insight and analysis. In particular, he is most famous for formulating the 3,959 rules of Sanskrit morphology in the text Aṣṭādhyāyī. His sophisticated grammar of Sanskrit continues to be in use to this day. The Indian grammatical tradition is believed to have been active for many centuries before Pāṇini, and anticipates by millennia certain developments in the West, such as the phoneme and the generation of word forms by the successive application of morphological rules for example. (Outside of India, the phoneme seems to have been discovered and forgotten several times through history.) This article or section does not cite its references or sources. ...

The South Indian linguist Tolkāppiyar (c. 3rd century BCE) wrote the Tolkāppiyam, the grammar of Tamil, which is also still in use today. Bhartrihari (c. 450510) was another important author on Indic linguistic theory. He theorized the act of speech as being made up of three stages: conceptualization by the speaker; performance of speaking; and comprehension by the interpreter. The work of Pāṇini, and the later Indian linguist Bhartrihari, had a significant influence on many of the foundational ideas proposed by Ferdinand de Saussure, professor of Sanskrit, who is widely considered the father of modern structural linguistics.

It is now generally accepted that India was the birth place of several mathematical concepts, including zero, the decimal system, algorithm, square root and cube root. The concept of zero origininated in Indian philosophy's concept of "sunya", literally "void". A symbol for zero emerged to represent this philosophical concept. 0 (zero) is both a number and a numerical digit used to represent that number in numerals. ...

Algebraic theories and other mathematical concepts circulating in ancient India, were collected and further developed by Indian mathematician Aryabhatta, who lived in the 5th century in Patna city (then called Pataliputra). He referred to Algebra (as Bijaganitam) in his treatise on mathematics named Aryabhattiya. A 12th century mathematician, Bhaskaracharya, authored several mathematical treatises; one of them, Siddantha Shiromani, has a chapter on algebra. He is known to have given the basic idea of Rolle's Theorem and was the first to conceive of differential calculus. In 1816, James Taylor translated Bhaskaracharya's Leelavati into English. Another translation of the same work by English astronomer Henry Thomas Colebruke appeared in 1817. The Arabs and Persians fine-tuned and internationalized these mathematical concepts. Persian mathematician Al-Khawarizmi developed a technique of calculation that became known as "algorism." This was the seed from which modern arithmetic algorithms have developed. Al-Khwarizmi’s work was translated into Latin under the title Algoritmi de numero Indorum, meaning "The System of Indian Numerals."

In 2001, archaeologists studying the remains of two men from Mehrgarh, Pakistan, made the discovery that the people of Indus Valley Civilization, even from the early Harappan periods (c. 3300 BCE), had knowledge of medicine and dentistry. The physical anthropologist that carried out the examinations, Professor Andrea Cucina from the University of Missouri-Columbia, made the discovery when he was cleaning the teeth from one of the men (see History of medicine). Later research in the same area found evidence of teeth having been drilled, dating back 9,000 years.

The science of medicine in ancient India is known as "Ayurveda", literally, "the science of life or longevity" in Sanskrit from "ayur" (age or life) and "veda" (knowledge). Ayurveda constitutes ideas about ailments and diseases, their symptoms, diagnosis and cure, and relies heavily on herbal medicine, including extracts from several plants.

Ancient scholars of India like Atreya,[2] and Agnivesa have dealt with principles of ayurveda as long back as 800 BCE. Their works and other developments were consolidated by Charaka into a compendium of ayurvedic principles and practices ,Charaka-Samahita, which remained a standard textbook for almost 2000 years, translated into many languages including Arabic and Latin. It deals with a variety of matters covering physiology, etiology and embryology, concepts of digestion, metabolism, and immunity. Preliminary concepts of genetics are also mentioned; for example, Charaka theorized that blindness from the birth is not due to a defect in the mother or father, but originates in the ovum and the sperm.

Advances in the field of medical surgery were also made in ancient India, including plastic surgery, extraction of catracts and even dental surgery. The roots of ancient Indian surgery go back to at least circa 800 BCE. The medical theoretician and practitioner Sushruta lived around the 6th century BCE in Kasi (now called Varanasi). He wrote the medical compendium Shushruta-Samahita describing at least seven branches of surgery: Excision, Scarification, Puncturing, Exploration, Extraction, Evacuation, and Suturing. It also deals with matters like rhinoplasty (plastic surgery) and ophthalmology (ejection of cataracts). It also focuses on the study the human anatomy by using a dead body. Shushruta also describes over 120 surgical instruments, 300 surgical procedures and classifies human surgery in 8 categories. Because of his seminal and numerous contributions to the science and art of surgery he is also known by the title "Father of Surgery." Susrutha is also the father of plastic surgery and cosmetic surgery since his technique of forehead flap rhinoplasty (repairing the disfigured nose with a flap of skin from the forehead) that he used to reconstruct noses that were amputated as a punishment for crimes, is practiced almost unchanged in technique to this day. The Susrutha Samhita contains the first known description of several operations, including the uniting of bowel, the removal of the prostate gland, the removal of cataract lenses and the draining of abscesses. Susrutha was also the first surgeon to advocate the practice of operations on inanimate objects such as watermelons, clay plots and reeds; thus predating the modern practice of the surgical workshop by hundreds of years.

Yoga is a system of exercise for physical and mental nourishment. Its origins are shrouded in antiquity and mystery. Since Vedic times, the principles and practice of yoga have crystallized. But it was only around 200 BCE that the fundamentals of yoga were collected by Patanjali in his treatise Yogasutra ("Yoga-Aphorisms"; see Yoga Sutras of Patanjali). In short, Patanjali surmised that through the practice of yoga, the energy latent within the human body may be released, which has a salubrious effect on the body and the mind. Modern clinical practices have established that several ailments, including hypertension, clinical depression, amnesia, acidity, can be controlled and managed by yogic practices.

"As far as the sixth century BCE Hindu physicians described ligaments, sutures, lymphatics, nerve plexus, fascia, adipose and vascular tissues, mucous and synovial membranes, and many more muscles than any modern cadaver is able to show. The doctors of pre-Christian India shared Aristotle's mistaken conception of the heart as the seat and organ of consciousness, and supposed that the nerves ascended to and descended from the heart. But they understood remarkabley well the processes of digestion – the different functions of the gastric juices, the conversion of chyme into chyle, and of this into blood. Anticipating Weisman by 2400 years, Atreya (ca 500 BCE) held that the parental seed is independent of the parent's body, and contains in itself, in miniature, the whole parental organism."
