teaching ends; exams begin.

today at 10am, i will proctor an 0DE exam;
at 1pm, we start grading:

4 class sections,
each with a class size limit of 70 students.

this might take a while.

my guess: if i get to thinking about research at all today, then it will happen no earlier than 8pm.

despite the end of classes, research is slow: my own fault. lately i seem unable to generate any good ideas, and i get distracted by,

among other things,
the m0nge-kant0rovich mass tran$p0rt problem.
