Journey to the Attoworld with Prof. Sreerup Raychaudhuri

Prepare to dive into the intricacies of the unseen realm as Department of Physics is organising an Eminent Guest Lecture Series, where Prof. Sreerup Raychaudhuri will unfold the mysteries of the Attoworld on January 31, 2024. An experience that transcends the limits of the known, promising a captivating journey through the frontiers of physics.

Mark your calendar to venture into the cosmos of the infinitesimally small, seeking to unravel the secrets that shape our understanding of the universe.

About the Speaker

Prof. Sreerup Raychaudhuri works on the physics of elementary particles and their interactions. He is a Ph.D. from the University of Calcutta and worked as a postdoc first at TIFR and then at CERN, Geneva. He taught Physics at IIT Kanpur for several years before joining TIFR, where he is now a Professor of Theoretical Physics and Dean (Administration). His research interests are interfacing theory with experiments, especially in the physics of electroweak interactions. He is also interested in the popularisation and history of science.

Abstract

Over the past twelve decades, we have gathered an incredible amount of information about the world at tiny length scales going down from a nano-metre – the size of a small molecule – to the order of an atto-metre – a billion times smaller – which is the limit of today’s experiments. We have found the most amazing structures and interactions which could not have been dreamed of in earlier times. We will trace the story of this great adventure from an empirical viewpoint and ask if we have finally unravelled the ultimate building blocks of the Universe.
