A Collection of Quotations (Gathered by a Former Student in APMA 203, Vector Calculus)

** ****- On the
difficulty of planetary motion equations (deriving Kepler's Laws)**

"Even if I waved my arms hard enough to fly, I'm not going to be able to complete a solution by the end of class."

* - On those
"damned tree diagrams" (for partial derivatives)*

"I will absolutely stand on my haunches and prevent a tree diagram from appearing on any quiz."

** **

* - Following several minutes of
alternately staring at his notes on paper, and those on the board *

"I'm lost. I don't know what to do." -Immediately following this remark, the entire class laughed, then got up and left.

* - This came out of
nowhere *

"I better practice my German. I'm going to visit some friends near Cologne in June. Then we go through Italy, and end up in France. It's terrible..."

** - So did this (in
relation to polar plots of cycloids)**

"I used to have a little toy when I was a kid, called a hootenannie. I still have it. It's in a box.... in the attic..."

* - On finding centers of mass in three
dimensions (and moments of inertia)*

"The mass is not only changing along the teeter-totter, but the kid sitting on it is pretty fat, so you have to integrate sideways as well."

* - For all occasions (as an alternative
to analytic solutions)*

"Let me show you how to do this (numerically) in FORTRAN 90."
