Fortnightly links (3)

More fortnightly links.

• I announced this already via Google+, but let's to it here too. We are organising a conference at the University of Antwerp. If you are part of the mathematical audience of this blog, you might be interested in attending. The list of speakers is frikkin' awesome so far.
• The slides and videos for the Miami conference on mirror symmetry are available. The cubic fourfolds from an earlier post (whose rationality is still open it turns out: the paper was retracted) make a guest appearance in Orlov's lecture, around the 38 minute mark, and during the question session.
• A comic on how to teach math. There is also the following related joke by the neverending author.
