The essays that are most frequently updated tend to be those of more than ephemeral interest. The following are those that have received recent additions (in some case, as recently as ten minutes ago):
(A) Mathematics
* Consilience, right-side-up and upside-down
Now with a shout-out to our flippered friends the porpoises !

Added a mention of the Dylan song of that title; plus a plea to the readership.

This essay is a pendant to the post above; but whereas the notion of “difficulty” is extrinsic, and relativized to contingent human limitations, “depth” is intrinsic, and dwells within the very being of mathematics.
(B) Politics
Rumbles from around the world, including today's events in Rome.
Part of an attempt to prevent the phrase “President Romney” from ever entering our vocabulary.
