to plant a non-threatening seed of skepticism into the minds of all present.

I kind of tried to do that, by making sure all my comments in the discussion afterwards were about the actual physics content, and reductionism, and how scientific ideas are evaluated... But I'm not incredibly charismatic, or especially good at breaking physics down into easily-teachable segments on the spot, and I think most people's reaction was to assume I was really smart and then stop trying to understand anything. (At least six people asked me if I'd thought about switching my major to physics...I had to explain that I hadn't because I'm not actually really smart, at least not enough to be a good theoretical physicist, and if the choice is between being a mediocre-to-poor physicist or an awesome nurse, I'd pick being an awesome nurse any day.)
