On the birth anniversary of #JagadisChandraBose, I proudly remember the moment in 2012 when, as the Head of Physics at #PresidencyUniversityKolkata, I received, along with VC Malabika Sarkar, the #IEEE #MilestonePlaque recognising Bose's seminal contribution to microwave research Dr Peter Staeker, then President-Elect of IEEE, had flown from New York to confer this honour. This was the first #IEEE plaque given to an Indian Institution. Later the same day, a second such milestone plaque was presented to IACS to commemorate the work done by C V Raman there

It is a Diwali tradition at IUCAA that second year students will choose the annual theme, and decorate IUCAA with traditional diyas and rangoli, but with a contemporary twist. All students and postdocs at IUCAA team up to create this Diwali magic.

Happy Deepavali everybody! This year's Nobel Prize is depicted by two thousand oil lamps (diyas) in the @iucaapune Kund. In the upper half are some of the stellar orbits around the #SupermassiveBlackHole at the centre of our Galaxy that got #AndreaGhez and #ReinhardGenzel the #NobelPrizePhysics this year.
