Eric Schulze just received his doctorate at the Keck School of Medicine. Asked by his colleagues to give a commencement address, he opted to discuss the things he should've been taught about science when he started out.

At 3:20, he quotes an "eminent cosmologist [sic; the man to whom Eric is referring is actually more of a general astronomer-type and smart ass] and teacher". I'm very sure the man to whom Eric is referring is grateful.
