| 30 | KHAG L | No. 136 - APRIL 2025 Fergusson College Outreach Debarati Chatterjee (IUCAA) and Saurabh Salunkhe (IUCAA) were invited to present a special session on LIGO-India and its outreach activities at the Frontiers in Physics conference at Fergusson College, Pune, on February 12. Their interactive talks covered the fundamentals of gravitational wave science and discussed the diverse career opportunities offered through the LIGO-India project. National Science Day at IUCAA On February 28, IUCAA celebrated National Science Day, honouring Dr. C.V. Raman's contributions to science. The LI-EPO team set up an engaging booth focused on gravitational wave science. Several models and demonstrations were showcased, including: A perihelion shifts model of Mercury to illustrate the difference between Newtonian and Einsteinian gravity A scaled-down model of the LIGO-India detector A gravitational wave generator simulatingmergers of compact objects A space-time fabric model explaining gravity and gravitational waves A gravitational wave activity kit for children A Michelson interferometer model to demonstrate how LIGO detects gravitational waves These models helped demystify complex scientific concepts for a diverse audience and sparked curiosity among young visitors. • • • • • •
