Physical lecture discussions this week

As already pointed out on Friday, the new regulations seem to allow teaching with physical presence for small groups like ours - and this doesn't seem to have changed with the announcement from the press conference tonight. 

I will continue to put out videos (and slides), but the additional lecture discussions will take place physically this week (w 9); for next week we can assess whether it is better to continue like that or fully digital.

NB: Remember to prepare general questions about differential geometry for Tuesday: this is the last lecture on differential geometry, so it's a good time for a break and general Q&A round!
