Finally the day has come when the enthu people could find some common free time to sit together and watch the STRING THEORY lecture part 1 by Prof Shiraz Minwalla. This was not a new lecture video by the way, it was just taken from his TIFR webpage http://theory.tifr.res.in/~minwalla/ . Although these videos are accessible to all, Prof Ramadevi wanted us to sit together and watch such that if there is any doubt, students can ask her. It was however very difficult in the past to find a common free slot out of the tight semester schedule in IIT Bombay. But yesterday people agreed to come for it although it was a national holiday on the occasion of Eid. The first lecture was very elementary, he started with a little motivation for doing strings and then went on to discuss relativistic point particle action, the reparameterization invariance (under one to one mapping between 2 parameter space), use of lagrange multipliers in the action etc. He also made a gauge symmetry interpretation of the reparameterization invariance. I just had a small doubt if we can have a lie algebra kind of interpretation of this gauge symmetry like we have in our standard model of particle physics. Prof Ramadevi commented that this reparameterization is something more general (like a general coordinate transformation) and hence need no be specific to lie algebra. From non-academic point of view also it was enjoyable, you can guess the reason if you are aware of Prof Minwalla's body language..:P. We are planning the screening of his second lecture next week. Hope to see more people there than yesterday.
