Synthesis and Adaptation

  • Adoption of new instruments (e.g., astrolabe).
  • Wider use of Arabic numerals.
  • Translation of Sanskrit texts to Arabic/Persian and vice-versa.

Architecture & Engineering

  • Indo-Islamic Architecture (Qutub Minar, Taj Mahal).

Medicine

  • Introduction of Unani system, integrated with Ayurveda.
  • Establishment of hospitals and medical schools.

Textiles & Crafts

  • Continued excellence in weaving, dyeing (Calico, Chintz, Muslin).
  • Development of pottery, glass-making, jewelry.

Overall Trend:

While impressive in applied fields like architecture and military technology, fundamental scientific research in mathematics and astronomy saw a relative decline compared to the ancient period, possibly due to changing patronage and intellectual priorities.

Colonial Era: Imperial Interests & Indigenous Response

British colonial rule significantly reshaped S&T in India, primarily to serve imperial interests, which had a mixed impact on indigenous scientific growth.

Early 19th Century

Initial British Scientific Endeavors

  • Surveys: Great Trigonometrical Survey (1802-1871), Botanical Survey (1890), Geological Survey (1851) for resource extraction.
  • Medical Research: Focus on tropical diseases for colonial staff.

Source: Spectrum, IGNOU

Mid-19th Century Onwards

Impact on Indigenous S&T

  • Decline of Traditional Systems: Lack of patronage for Ayurveda, local crafts.
  • Limited Indigenous Development: India as raw material source, market for British goods.
  • Educational Neglect: Macaulay's Minute (1835) favored English education for administration.
1835 - 1857

Establishment of Western-style Institutions

  • Medical Colleges: Calcutta Medical College (1835).
  • Engineering Colleges: Thomason College (now IIT Roorkee, 1847) for public works.
  • Universities: Calcutta, Bombay, Madras (1857) for administrative staff.
Late 19th - Early 20th Century

Emergence of Indian Scientists (Despite Constraints)

  • Jamsetji Tata: Supported IISc Bangalore (1909).
  • J.C. Bose: Radio, microwave optics, biophysics.
  • C.V. Raman: Nobel Prize (1930) for Raman Effect.
  • Meghnad Saha: Saha equation.
  • S.N. Bose: Bose-Einstein statistics.
  • P.C. Ray: Pioneer of chemical research.

Overall Colonial Impact:

The colonial era created a dualistic S&T structure: limited modern institutions serving colonial needs, alongside neglected traditional sciences. However, it also saw the rise of brilliant individual Indian scientists who worked with limited institutional support, often fueled by nationalist sentiments and individual dedication.

Post-Independence: Building a Self-Reliant Nation

After 1947, India embarked on a concerted, state-led effort to build a robust S&T infrastructure, central to its vision of self-reliance (Atmanirbharta) and national development under the Nehruvian vision.

Nehruvian Vision (1947-1964)

  • Scientific Temper: Advocated by Jawaharlal Nehru (Article 51A(h)).
  • Self-Reliance: S&T as key to industrialization and agricultural modernization.
  • State-led Development: Public sector investment in large S&T projects.
  • "Big Science": Focus on strategic areas like nuclear energy and space.

Key Policy Milestones

  • Scientific Policy Resolution (SPR) 1958: Foundation for S&T infrastructure.
  • Technology Policy Statement (TPS) 1983: Focus on indigenous tech development.
  • Later Policies: STP 2003, STIP 2013, STI Policy 2020 (draft) adapting to new challenges.
