Matter and Interactions: Post-Mortem

OK, it’s not really a full post-mortem, because I haven’t graded the final exams yet, but I wouldn’t tell you about those, anyway. Still, I wanted to take a moment to reflect on the past term, which was my first teaching introductory mechanics on the Matter & Interactions curriculum. On the whole, I continue to… Continue reading Matter and Interactions: Post-Mortem

Nobody Expects the Vector Product

Today is the first day of the last week of class, hallelujah. Unfortunately, it’s also the first class on rotational motion and angular momentum. This is unfortunate because it’s the hardest material in the course– angular momentum doesn’t behave in as intuitive a manner as linear momentum, and the math involved is the most complicated… Continue reading Nobody Expects the Vector Product

Projectile Motion, Uncertainty, and a Question of Ethics

We no longer do what is possibly my favorite lab in the intro mechanics class. We’ve switched to the Matter and Interactions curriculum, and thus no longer spend a bunch of time on projectile motion, meaning there’s no longer room for the “target shooting” lab. It’s called that because the culmination of the lab used… Continue reading Projectile Motion, Uncertainty, and a Question of Ethics

Making Physics Relevant

An example problem from today’s lecture: A sleep-deprived parent is warming a bottle for a midnight feeding. He places a bottle containing 250 ml of infant formula at 275K into 300 ml of water at 320 K. When the two liquids reach equilibrium, what is the temperature of the formula?

Would You Like Some Calculus With Your Physics?

It’s a nice demonstration of the oddity of the blogosphere that a libertarian political blog has become my go-to-source for thoughtful blogging about physics education. Thoreau had two good posts yesterday at Unqualified Offerings, one on the problems created by breaking down incorrect intuition, and another on the lack of calculus in calculus-based physics texts:… Continue reading Would You Like Some Calculus With Your Physics?
