He LOVES physics.
As a lifelong learner (aprenc tant existeixo: I learn, therefore I am), I've been taking Coursera classes on economics, language, physics & more. I'm not sure how much I'm taking in—let alone retaining—but I do like how enthusiastic the teachers are & how much they want us to appreciate their subjects. This physics guy ("How Things Work") can't believe how cool these formulas are: don't we agree?!!?! I barely passed the first test, even though I was paying attention. That was yesterday, & if I had to take it today, I doubt if I could still remember velocity, mass, acceleration, the newton, & how they interact (or do they?).
