I will be trying to link the talks that I give to this blog so that I have a record of these, and just in case one of you is also interested.
On September 10, 2008 I gave a talk here at CHEP in honour of the first beam at LHC. It was one of the best attended talks that I have given and to my satisfaction many students seem to have liked it. The link for the pdf file is here.
A shorter version was given as a colloquium at Physical Research Laboratory, Ahmedabad and the link for the pdf file is here.
