[300th entry in this 'blog! Hurray, hurray, hurray!]

At the end of 2001, I had started a mathematical diary, which I kept
active through most of 2002. The idea is *not* to write down
ideas that are important for my current mathematical research activity
(writing my thesis, that is), but, on the contrary, to evacuate by
committing them on paper various side ideas that I have from time to
time. It's the same sort of force that drives me to write this 'blog:
once I become infected with a meme, say a mathematical problem,
it will keep haunting me until I either solve the problem or save it
on paper (electronic paper will do as well, of course) for later. So
this is how this diary should be regarded: as a meme pool of weird
ideas. There is nothing that could be called “mainstream
mathematics” in it, I guess. Some of these memes are
“abstract nonsense” as mathematicians call it, embryos of
theories that are trivial to work through the basic definitions, which
produce pages and pages of easy writing. Some are (presumably hard)
questions.

In a way, this diary could be shown as evidence of my mathematical
angst: probably nothing it contains would be deemed of any interest by
any other mathematician, and I guess the questions which obsess me are
very much *alien* to mainstream mathematical culture. This is
one of the reasons why I have solid doubts as to whether I should
pursue the academic career in mathematics.

Anyway, whatever it's good for, I've decided to start writing in this diary again. Probably not nearly as actively as this 'blog, but it'd be nice to hold a one-entry-a-week minimum average. There are lots of goofy thoughts that I won't be rid of until I've written them down.
