Father of Surgery; 
authored Sushruta 
Samhita detailing over 
300 surgical 
procedures including 
plastic surgery and 
cataract operations
Acharya Jagadish Chandra Bose
Conducted groundbreaking research in radio waves and 
plant science; demonstrated wireless signal 
transmission before Marconi

Modern Indian Pioneers
Sir C.V. Raman (1888-
1970)
Awarded the Nobel 
Prize in Physics (1930) 
for discovering the 
Raman Effect4the 
change in wavelength of 
light when scattered by 
molecules. This 
phenomenon became 
fundamental to 
analyzing molecular 
structures.
Founded the Indian 
Academy of Sciences 
and established 
research laboratories 
nationwide.
Homi J. Bhabha (1909-
1966)
Known as the Father of 
Indian Nuclear Program. 
Established the Tata 
Institute of Fundamental 
Research (TIFR) and the 
Atomic Energy 
Commission.
His vision led to India's 
self-reliance in nuclear 
energy and the three-
stage nuclear power 
program.
M.S. Swaminathan 
(1925-2023)
Architect of the Green 
Revolution in India, 
introducing high-
yielding varieties of 
wheat and rice.
His work transformed 
India from food-
deficient to food-
sufficient, saving 
millions from starvation 
and establishing 
agricultural self-
reliance.

India's Scientific 
Journey Through 
Time
India's scientific progress spans from ancient 
mathematical innovations to leading the world in 
cost-effective space exploration. This journey 
reflects persistent indigenous innovation despite 
historical challenges.
Exam Tip: Remember specific years for 
major scientific breakthroughs like 
Raman's Nobel Prize (1930), 
establishment of ISRO (1969), Pokhran 
nuclear tests (1974, 1998), and recent 
missions like Chandrayaan-3's 
successful landing (2023).
