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

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

Object tracking in Mathematica
I’ve been playing with ImageFeatureTrack in Mathematica over the last few days. My interest is in helping me and my students track the beads on a swinging beaded chain (something we worked on quite a bit last summer). I just … Continue reading

Visualizing eigenvectors
When I was in undergrad, I dutifully did all my linear algebra homework, not really understanding why. I figured, “if they want me to find a vector or two for a given matrix that satisfies M.v=lambda v , fine, I’ll do it.” … Continue reading

Fourier analysis for nonscientists
Yesterday I went on twitter to try to get some help on teaching Fourier analysis for my sound and music class: teaching fourier theory to nonsciSs. Goal: that it's possible (to find freqs). notagoal: teach slickest way to do the … Continue reading

Creating supplemental texts
I’m nearing the end of a semester where, for one class, there was no official text. That’s going decently well, though I’ll likely have more to say about that in another post. What I want to talk about here are … Continue reading

Lagrange multipliers
This is a post that builds on my previous notes about the calculus of variations. This week I’m going to teach about modeling constraint forces using the Lagrangian approach, and I wanted to put these notes down for my current … Continue reading
