The Talk

It was a nice talk. Similarly as Michael Freedman in the first talk, the speaker managed give an accessible talk to a rather general audience. The talk still did not convince me that the mass gap problem is a good problem. The talk could have been given 40 years ago when I was a student. I have added some slides below. I have added a few more comments on my blog.
