in case you must chat in $$'s ..

i wouldn't say every day, but most days i learn something new.

as for today, i learned ..

1. .. about Wolff potentials (of measures), i.e.
   
   
   and how they come up in PDE, occasionally.
   
   
   
2. .. that there is a LaTeX-based web chat program called MαthIM.
   
   since nobody claimed the name yet, i have started a chatroom called quasiworld and posed a random question that came to mind, some months ago.
