Presented in another conference namely "Let There Be Light" during March 2025. This is a unique conference in which presentation is of "Chalk-Board" type and discussion time is much more than the presentation time. Thoroughly enjoyed the discussion. Kudos to Prof. Naresh Patwari.

Prof. Maksym Kovalenko delivered an excellent Institute Colloquium of very high depth & versatility at IISER Kolkata recently. In India it's a tradition to show the highest respect to a revered person by putting a shawl on his shoulder. Prof.Kovalenko is definitely such a person.
