La la la links

In lieu of commentary on incompatibility semantics today, here are a couple of worthwhile links.

The first is a tutorial on how to use Zorn's lemma by Tim Gowers. It is quite good and has several examples.

The second is a short piece on time management by Terry Tao. Most productivity stuff I read online is aimed more at the business or tech industry crowd, so I enjoyed reading suggestions by a successful academic aimed at the academic crowd.
