Top Physics Honour For Prof Ashoke Sen, Working To Unify The Laws Of Universe, Pg1

Key Highlights:

• Professor Ashoke Sen, a distinguished Indian theoretical physicist, has been awarded the Oskar Klein medal for his pioneering contributions to physics.
• He is the first Indian physicist to receive this international honour, which recognizes distinguished contributions to physics.
• Sen is renowned for his work in string theory, particularly for demonstrating the equivalence of different string theories.
• His research aims to unify the theory of gravitation and quantum theory, bridging inconsistencies between them.
• He currently serves as an ICTS-Infosys Madhava Chair Professor at the International Centre for Theoretical Sciences (ICTS) in Bengaluru.

Detailed Insights:

• The Oskar Klein medal is awarded annually by Stockholm University and the Nobel Committee for Physics of the Royal Swedish Academy of Sciences.
• String theory posits that fundamental particles are not point-like but rather tiny, one-dimensional vibrating strings.
• Sen's significant breakthrough involved showing that various seemingly distinct string theories were mathematically equivalent, suggesting a single underlying physics.
• His contributions also include pioneering work on S-duality, the Sen conjecture on unstable D-branes, and the entropy function formalism for black holes.
• Professor Sen has received numerous accolades, including the Shanti Swarup Bhatnagar Prize (1994), Padma Shri (2001), Infosys Prize (2009), Breakthrough Prize in Fundamental Physics (2012), Padma Bhushan (2013), and the Dirac Medal (2014).
• He was elected a Fellow of the Royal Society (FRS) in 1998.
• Sen's career includes research at the Tata Institute of Fundamental Research (TIFR) and the Harish Chandra Institute before joining ICTS.

Scientific/Technical Concepts Involved:

• String Theory: A theoretical framework proposing that the fundamental constituents of matter are one-dimensional vibrating strings, not point particles.
• Theory of Gravitation: Describes the attractive force between masses, governing large-scale phenomena like planetary motion and galaxy formation.
• Quantum Theory: Explains the behavior of matter and energy at the atomic and subatomic levels.
