Dear All,

The Department of Physics invites you to a colloquium on "EINSTEIN & HIS FAMOUS EQUATION   E = mc2" by Prof. Ajoy Ghatak, Honorary Professor at Optics & Photonics Center, IIT Delhi.

Abstract: The equation E = mc2 is probably the most famous equation. Einstein derived this equation in his Year of Miracles (1905). In this lecture, by considering a few examples, we will try to understand what exactly it means– and its consequences including as to how a star like our Sun was created. We will also give a simple derivation of the equation E = mc2 . The talk will be based on his recent book EINSTEIN, E = mc2and THE ATOM BOMB – recently published by VIVA Books.

About the Speaker: Prof. Ajoy Ghatak is currently Honorary Professor at Optics & Photonics Center, IIT Delhi. During Jan 2021- Dec 2022, he was the President of The National Academy of Sciences, India – the oldest Science Academy in India. He did his MSc from Delhi University and PhD from Cornell University. He is a Fellow of OPTICA (formerly OSA) and SPIE. He has authored several books including his undergraduate text on OPTICS which has been translated to Chinese and Persian. He is recipient of several awards including the 2003 OSA Esther Hoffmann Beller Award and the  2008 SPIE Educator award which was in recognition of “his unparalleled global contributions to the field of fiber optics research, and his tireless dedication to optics education worldwide..” and also the  CSIR 1979 S S Bhatnagar award. He received the OSA 2020 Sang Soo Lee award for his seminal role in the development of fiber optics and guided wave photonics and for pioneering optics education in India  and the 2021 SASTRA-G N Ramachandran Award for Excellence in Physics .  

We look forward to your active participation.
