MathJax posts
My posts on the string bend calculator used MathJax to display the equations used. But I ended up struggling a while to get them to work on mobile devices. The problem is this: typically MathJax loading needs to go into the document head, but that means editing your blog template.

Bending with Dojo part 3: Slight return
This is the last of three posts about building the string bend calculator and maybe the most interesting to anyone other than me. Part 1 dealt with the basic physics and Part 2 with building the Javascript app. All that's left is to wonder what it all means.
Bending with Dojo part 2: Stretching in the Dojo
Following on from Part 1, I wanted to make an interactive way to explore the mechanics of string bending. A spreadsheet is the simplest way to do that, but it needs users
to download a file and open it up with the right program. A web-app
only needs a browser and internet access to use, but takes a bit more
assembly. To cut down the amount of DIY needed it's common to use a framework. JQuery is probably the most commonly used, but without built-in support for plots, so I went for the slight more complex Dojo.
I tried to make the maths background in Part 1 understandable for a general audience, but this Dojo section is going to have to assume you know a few programming terms. If that doesn't sound like your thing, then maybe you're just looking for the string bend calculator.
