"At <a href=""https://www.youtube.com/watch?v=K78jqx9fx2I&amp;t=1h11m00s"">1:11:00</a>", "I represent science" can be interpreted in 2 completely different ways, one seems arrogant and the other is the opposite: as in, "at my core, what I am about is the honesty and rigor and beauty of science, who I am is that at my core, not as an ego thing but the opposite".  I think Lex's sometime weak English can lead him to taking this in the wrong way.
