:: student work ::I solved the PSU parking garage puzzle only to have the login puzzle dog me in class. I solved that too, by starting from the bottom of my list and initializing new, unused accounts.
In addition to showing some animations, I gave a short lecture on vector algebra, focussing on the difference between left and right handed XYZ, and four vector ops: __add__, __neg__, __sub__ and __mul__ (note Python __rib__ syntax). See my CP4E write-up for more context.
On behalf of Saturday Academy, I handed out certificates of completion, with sa: staff coming by to collected the confidential student evals.
