What did I do over Thanksgiving? I read Ernie Croots's excellent exposition of Szemeredi's Regularity Lemma which is here
It is sometimes easier to learn stuff when you are AWAY from
your computer. Less distractions. BUT if you need to look something
up, its harder. BUT this may force you to think harder.
BUT maybe you need to look something up and can't derive it yourself
BUT, BUT, BUT...
However, it worked this time.
I also came up with a trivial math problem based on real life.
I got into an elevator that had 23 floors and was going to
the 4th floor. Two people got in and BOTH pushed
buttons that were LESS than the 4th floor and diff from each other.
I later thought `Gee, you would think being on the 4th floor you
wouldn't stop twice to get there. What is the probability of that happening?'
I had the answer in about 1 minute. Much easier than understanding
Szemeredi's Regularity lemma.
