Finding normal modes

Normal mode analysis is a typical topic in junior/senior mechanics courses. Ours suffers from a lack of linear algebra as a prerequisite so I’ve worked to find ways to engage students with this material without that background. My typical approach … Continue reading

Maxwell to Snell

Today was a really interesting day in my optics class. We’re doing chapter 9 in our text and I wanted to make sure that I motivated the material well. What’s weird about this text is that it waits until chapter … Continue reading

Group digital lab books

Last summer I bought a LiveScribe Sky pen for my lab group, with the hope that we’d connect it to a group Evernote account that we’d use as a group lab notebook. Unfortunately, it didn’t work very well. The Evernote … Continue reading

Relativistic explosions

Earlier this week I got an email from a friend who has been working with his students modeling how momentum works in a situation where two carts start connected and then explode apart. I’m not sure, but I think that … Continue reading

Leaving a gaping hole

This past week in my optics class I think I made a mistake. We were talking about how light interacts with a system with multiple parallel interfaces, and we started with analyzing a single interface that didn’t happen to be … Continue reading

Finding grains

My colleague asked me to help him out with this image: He needs to know the grain size distribution, and they’ve been having trouble automating this. He knew I’d been doing some work with Mathematica’s image analysis capabilities so he … Continue reading
