- 1. History of Science & Technology in India
- 2. Characteristics of Science • Text for visuals • Science is an intellectual and practical activity – systematic study of the structure and behavior of the physical and natural world through observation and experiment • Science is Universal and belongs to the People • World view of Science is common heritage • The development and the direction of science is dependent on socio-political- economic dynamics in society as it is fund dependant of the ruling Govt. • Ruling Govt. Decides Science Development
- 3. Characteristics of Technology • Text for visuals • Technology is a collection of techniques, skills, methods and processes for the production of goods or services or for objectives such as scientific investigation. • Technology can be the knowledge of techniques, processes or can be embedded in machines which can be operated without detailed knowledge of their workings. • Which technology is utilized and for whom depends on socio-political- economic dynamics in society • Technology is not static, but evolves as it is passed on in time and space • Technology depends upon the Society
- 4. •Text for visuals •Myth is any traditional story •consists of imaginary events were passed on in oral history •explains origins of a cultural practice or natural phenomenon •Eg: Rahu, Ketu for eclipse; Mahabaratha, Ramayanas •Religions are based on Mythical Gods or historic person: •Rama, Jesus, Mohammed, Buddha, Confucius •Rituals help religions: eg.

- 5. Characteristics of manufactured S&T from myths • Assigning maximum antiquity to Vedic-Sanskritic Hindu traditions – 20,000 to 2 lakh years while in reality Vedas were composed during ‘Iron age’ (1500-500 BCE) • No concrete verifiable evidence cited for the claims – Birth of Rama, Adam Bridge • Ignores extensive interactions and exchanges between cultures and • civilisations thus denying universal character of S&T • Tries to establish superiority of one culture and way of thinking over others • All those who do not subscribe to this ‘greatness’ are termed outsiders or anti-national • Objecting Myths is labeled as anti National

India), binary numbers (Pingala), Brahmagupta, Aryabhata, Baskara II, cartography, indigo dye, Susruta Samhita
- 7. Science & Technology: Historical perspective Science and Technology before colonial exploitation 1100 CE – 1600 CE •Madhava of Sangagrama and Kerala school of astronomy and mathematics •Infinite series for π (pi) , trigonometric functions •Silver currency from Sher Shah of Northern India •Ali Kashmiri ibn Luqman’s seamless globe •Gun powder, pyrotechniques •Advanced irrigation systems •Cashmere wool •Sadiq Isfahani of Jaunpur 32 sheet atlas
- 8. Science & Technology: Historical perspective Science and Technology during colonial period 1600-1947 •Rockets (Sultan Hyder Ali of Mysore) •Extensive Railway network •Indian Postal System •Establishment of Calcutta, Madras, Bombay Universities •Creation of Indian Institute of Science by Jamshedji Tata •Eminent scientists – J.C. Bose, Prafulla Chandra Ray, S.N. Bose, Meghnad Saha, P.C. Mahalnobis, C.V. Raman, S. Chandrasekhar, Homi Bhabha, S. Ramanujam, Vikram Sarabai, Harish Chandra, Abdus Salam, Muthulakshmi Reddi, Janaki Ammal
- 9. Science & Technology: Historical perspective Science and Technology after becoming Independent 1947-1990 •Indian Constitution, in Article 51 A (h) states that it is part of the fundamental duties of citizens to “...develop the scientific temper, humanism and the spirit of inquiry and reform” •Establishment of more than 200 Universities, 5 IITs •Hybrid varieties: Green revolution (MS Swaminathan) •Edible oil manufacture, milk production •Bhakra Nangal dam, Kaveri engine (for Tejas Light Combat Aircraft) •Indian Space Research Organisation, DRDO •Missiles, IRS, INSAT •Creation of Tata Institute of Fundamental Research •Param supercomputer
- 10. Science & Technology: Historical perspective Science and Technology post globalisation 1990 till now •Privatisation through Public Private Partnership of education and research-Private Universities and Research Centres •Indian version of the Bayh Dole Act – Intellectual Property Bill •IT boom: Outsourcing – modern colonial exploitation •Technologies for exploitation of natural resources and mobile communication spectrum •Transgenics , biotechnology centres •Stopped indigenous manufacture of computers, equipments for research etc.
- 11. Science & Technology: Historical perspective PSM role •Campaign against pseudoscience •Campaign of our historical achievements of S&T to create confidence that we are capable. •The S&T in the 50 years after independence must be highlighted •Create a sense of freedom movement to fight globalization and neocolonialism •Modernize, popularize and replicate People’s Technology- like CTD/STD, MP-BGVS,IRTC,CERD
