[FRIAM] reasoning

[Frank Wimberly]

As for teachers who barely understood.what they were teaching...

At Carnegie Mellon the guy who usually taught digital signal processing was
on sabbatical, the guy who taught it when the first guy wasn't available
was just made director of the Robotics Institute.  I had mentioned a desire
to teach so they decided I should do it.  I said "but I never took that
course."  The RI guy said,  "You'll do fine. It's just math."  The course
was for about 40 MS and a few PhD students in EE.  The text was by
Oppenheim and Schafer.  As I read it I wondered where the theorems and
proofs were.  Long story short, with help from a control throry professor
who was available to answer my questions it went OK.  I'm sure most of the
students knew I was a beginner.  On the student evaluations I got 3.2 out
of 4.
