A while ago, I tweeted that I hoped Cambridge would allow us to post our online lectures publicly. I'm delighted to say that they do indeed allow this, so I shall be posting my course Topics in Combinatorics on YouTube as I give it. 1/

The first two videos (equivalent to one lecture) are now up on my fledgling YouTube channel. They are not particularly polished, but that wasn't the idea. 2/ https://youtube.com/c/TimothyGowers0

I just felt (very strongly actually) that if it is easy to share content like this, then it should be shared. I hope it will be a useful resource, particularly to people who are less privileged than the average Cambridge student, but if not, then there's no harm done. 3/

It's a graduate-level course, but doesn't need much by way of prerequisites, so much of it should be understandable to people with only one or two years of undergraduate mathematics behind them. 4/

I think (without being 100% sure) that a number of my colleagues feel the same way, so I hope other Cambridge maths courses will become available too, and will tweet about it when I have more information. 5/5
