Science & Mathematics in Ancient India
UPSC Notes
Ancient India made significant contributions to mathematics, astronomy, medicine, metallurgy and related sciences.
Mathematics
Decimal System
Indian mathematicians played a major role in developing the decimal place-value system.
The concept of zero as a number and placeholder became particularly important in the development of mathematics.
Aryabhata
Aryabhata was one of ancient India's most influential mathematicians and astronomers.
His famous work:
Aryabhatiya
Important contributions include:
- Mathematical calculations
- Approximation of π
- Trigonometric concepts
- Astronomical calculations
- Explanation of eclipses using astronomical principles
Aryabhata proposed that the apparent movement of the stars was related to the rotation of the Earth.
Brahmagupta
Brahmagupta wrote:
Brahmasphutasiddhanta
Important contributions:
- Rules involving zero
- Negative numbers
- Algebraic calculations
- Astronomical computations
Medicine
Ancient Indian medical traditions are associated with Ayurveda.
Important figures include:
Charaka
- Associated with internal medicine.
- Charaka Samhita is an important medical text.
Sushruta
- Associated with surgery.
- Sushruta Samhita contains extensive discussion of surgical procedures.
Metallurgy
Ancient Indian metallurgical knowledge is demonstrated by structures such as the Iron Pillar of Delhi, notable for its resistance to corrosion.
