IUCAA foundation day lecture on Dec 29

The 24th IUCAA foundation day lecture, one of the most coveted events for sky lovers in the city, will be organised on December 29. As part of the programme, Physicist professor Ashoke Sen will deliver a lecture on 'Search for a Unified Theory' around 5 pm at Chandrashekhar Auditorium.

Sen was recently in news for winning the biggest physics award, the 'Fundamental Physics Prize' which carries a prize money of $3 million. He got the award for 'uncovering striking evidence of strong-weak duality in certain supersymmetric string theories and gauge theories, opening the path to the realisation that all string theories are different limits of the same underlying theory'. In its maiden year, eight others also received the award with Sen the only Indian.

Sen is a researcher at the Harish-Chandra Research Institute in Allahabad, Uttar Pradesh.

In his lecture, Prof Sen will review our current understanding of the theory of the elementary constituents of matter and attempts to go beyond that. The lecture will be open to public free-of-cost and will also be webcast on www.livestream.com/scipop.

Prof Sen has made a number of major contributions to the subject of string theory , including a landmark paper which was influential in changing the course of research in the field. He pioneered the study of unstable D-branes and made the famous Sen conjecture about open string tachyon condensation on such branes. His description of rolling tachyons has been influential in string cosmology.
