National Science Day

Prof. Sabyasachi Bhattacharya, Director, TCG-CREST, Kolkata, gave a special talk on Feb. 28, 2022, on the occasion of National Science Day. This programme was one of the series of events held at the Centre for Nano and Soft Matter Sciences (CeNS) to commemorate the 75th anniversary of India's Independence – Aazadi Ka Amrit Mahotsava. The program began with a brief introduction to the speaker by Prof B LV Prasad, Director, CeNS.

            Prof Bhattacharya began by explaining the importance of National Science day, the discovery of the Raman effect by Prof Sir. C V Raman, its importance, usage in the present-day world. Followed by this, he gave a presentation on the title “Perfectly Reasonable Approximations: Dealing With the Real World”. In this talk, he discussed strategies used in the physical sciences to understand and utilize the "real" world through approximations/idealizations. He mentioned Feynman's "minimum sentence" remark and possible extensions using the well-known Fermi-problem methods. The aim is to illustrate both the power and the limitations of approximations, a subject rarely included in science curricula.
