Introductory videos and podcasts

Ulrik Fjordholm has made introductory videos to (almost) all parts of the course. I will link to them in the entries on the "Before the lectures" page, but to make them easier to find, I have also made a separate page where you can find them all (look for "Introductory videos" under "Resources").

For the time being we are also allowed to post untexted podcasts on the course page, and you will find them under "Reports from the lectures".
