RMS delivered the Silver Jubilee Lecture at Centre for Earth Science Studies (CESS) entitled "Copyright and Freedom in Science". It was more of a discussion than a lecture, and the discussion covered not just copyright but went into the philosophy of Free Software and its economic and business aspects. There were a number of young faces in the small but enthusiastic crowd of around 200. And, interestingly, some of the older members of the crowd also showed considerable interest in both the copyright aspect and Free Software. The discussions were lively and went on till we had to put a stop because of lack of time. There was reasonably good media coverage, with two camera crews present along with a few from the print media.
