ಮುಖ್ಯ ಅಂಶಗಳು
Remember these
- Ashoke Sen is the first Indian physicist to receive the Oskar Klein Medal.
- His key work: S-duality, precise counting of black hole entropy and string field theory.
- These ideas have shaped modern string theory, which seeks to unify gravity with quantum mechanics.
- String theory treats fundamental particles as tiny vibrating strings rather than points.

How the exam will ask it
ಪ್ರಿಲಿಮ್ಸ್
- Ashoke Sen is the first Indian to receive the Oskar Klein Medal, awarded for outstanding contributions in physics.
- S-duality in string theory relates a theory at strong coupling to another at weak coupling.
- Black hole entropy counting seeks to explain entropy through the microscopic states of a black hole.
- String theory is a candidate framework for a theory of quantum gravity.
ಮೇನ್ಸ್
GS-III Science and Technology: India's fundamental research strength is shown by theoretical physicists recognised globally. The issue is how sustained public funding of institutes and basic science, as through the National Research Foundation, yields frontier work like string theory. The implication is stronger talent retention and prestige; the way forward is more research funding, international collaboration and early nurturing of young researchers.
