My calc professor is awesome (similar to Morin haha). Apparently he's notorious amongst the chems, but for now he's been hilarious.
He says the best things in class:

Math is being intelligently lazy.

I think positive numbers are better than negative ones, at least in term of marks.

We've been going over trig using the unit circle, and I am convinced that it is magical. So many trig identities can be proved just by definition (sin^2(x)+cos^2(x)=1), while others is so much more intuitive than with triangles (cos(A-B)).

Other courses are alright, mechanics prof tells really cold jokes (and rules under a gentle dictatorship), phy chem prof is really monotone, ESP is said to be a lot of work, and lin alg will kill us all with nth dimensions :]
