What science is, from a freshly-minted scientist

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. His speech is an excellent introduction into why we need more gifted speakers talking about what science is and isn't: 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.
