I think there was one spread sheet that I had to view this semester.
It turned out to not be that important so I didn't really have to do
much with it.
I take good notes and don't really need power point presentations.
However something interesting, my astronomy teachers use powerpoint
to make their presentations, but you can download the lectures in PDF
form. Does anyone here know how that is done? That may be an option
for us perhaps.

"A man's memory is bound to be a distortion of his past in accordance
with his present interests, and the most faithful autobiography is
likely to mirror less what a man was than what he has become."
