Hello everyone on Blogosphere. It seems like a decade I am away from this blog except to those who are in space or in Miller's planet (courtesy: Interstellar). Coming back here was not a compulsion by the way, but a reflection of the fact that I have been living some beautiful days since November 9 in the city of Joy, Calcutta. The best part of these few days was the freedom I was awarded to do whatever I want which is rare in a government job. I am indeed thankful to my official as well as practical hosts in this city as well as to my university for sending me here. I came here on duty leave taking our students to the National Science Camp held during November 10-12 at Science City here. Although the organizers sent me a hard copy of invitation letter, they simply denied accommodation to me after my arrival, thanks to the lack of communication between national and local organizers. Although they took good care of our students, I had to roam here and there before somehow managing to get into the IACS guest house. Thanks to all who helped me out and gave me a place to stay at night within such a short notice and that too on a weekend. Although the trip to Calcutta started like this, it took off very smoothly as I could utilize my day time reading and discussing things at IACS theoretical physics department. I felt as if I am reading some new science after a long long time. The hectic teaching and administrative work schedule at my workplace hardly allow me to do something creative or read something new. Days were fun with science, whereas the evenings were fun with tasting new food with friends at places like Tandoor Park (Jadavpur), South City Mall (Jadavpur), Peter Cat (Park Street) etc. Visiting the Victoria Memorial at night was simply amazing, such a mesmerizing structure. My stay here also allowed me to watch the new movie Interstellar released last week. This would have never been possible in a small town like Tezpur where I work. Before leaving tonight, just thanking everyone who made my stay comfortable and enjoyable. Also a big thanks to the National Science Camp organizers who could not offer me a place to stay but finally paid for my stay at a place which I am sure is better than anything the organizers would have offered. Adios City of Joy, hope to visit again!
