Putting a math- & code-heavy textbook online

Some changes arrive with great drama and attention. Others creep in stealthily, like the gradually warming water that boils the proverbial frog (contrary to reality). I can’t think of the last time I welcomed the sight of a printed journal in my mailbox. Though I might print the occasional article that needs to be pored over slowly, I’ll recycle that copy after a bit; the electronic version is the one that I archive.

The sorry state of teaching ODEs

I’ve spent the last two spring semesters teaching ODEs (ordinary differential equations) to a total of about 170 biomedical and chemical engineering majors. The content is dictated by a number of constraints: the perceived desires of the client departments, multiple instructors, all of whom have more experience with the course than I do, and traditional expectations. Based on a limited survey of popular textbooks ( this, this, and our choice, Brannan and Boyce), many courses like this are quite similar.

Matlab vs. Julia vs. Python

I’ve used MATLAB for over 25 years. (And before that, I even used MATRIXx, a late, unlamented attempt at a spinoff, or maybe a ripoff.) It’s not the first language I learned to program in, but it’s the one that I came of age with mathematically. Knowing MATLAB has been very good to my career. However, it’s impossible to ignore the rise of Python in scientific computing. MathWorks must feel the same way: not only did they add the ability to call Python directly from within MATLAB, but they’ve adopted borrowed some of its language features, such as more aggressive broadcasting for operands of binary operators.

New look, new tech

At long last, I’ve refreshed the look for this site. Previously it was based on a “Metro UI” style for HTML, which looked nice to me at the time. Actually it still looks pretty nice, but it was named for the Metro design introduced with Windows 8, which tells you that it wasn’t exactly a modern look. More importantly to me, I’ve ditched writing raw HTML for creating a site using the Hugo content creation system.

Jekyll for clicker questions

For a few years, I’ve been a fan of clickers (aka personal response systems) for large lecture sections. Clickers are a simple–and scalable–way to incorporate a little widespread active learning in the classroom. They can’t work miracles, but they do allow me to reward attendance, rouse the students once in a while, and give good feedback to all of us about how well the latest concepts are sinking in. I like the accountability: If you got the question wrong when 80% of the class got it right, that’s on you, but if 20% of the class got it right, that’s on me.
