the preprint is almost done.
i'm trying to keep working. it's not easy.

today was the calculu∫ final for my students. desperate for research time, this morning i woke up at 7am and went right away to work, in efforts to get something done before the exam at noon. [1]

the proctoring took 2 hours [2],
the grading took 4 hours,
the sorting, data entry, and curve cutting took another 2 hours.

for some reason, the local coffeehouse closed today at 10pm;
i found another one that closed at midnight.

i really didn't want to work at home tonight,
but .. [sighs] it's almost done ..

on a related note: however the scores would turn out, i shook hands with half- to a dozen few students after the exam period.

in the end, i guess i managed to make some of them care about calculu∫, after all, or at least make the journey to stοkes's theοrem a little easier.

[1] on the bright side, i found a simple way to adapt our proofs to a more general setting.

[2] i've tried working during exam periods before, with no success: when proctoring exams, i find it hard to concentrate on anything else.
