Mathematics and physics
More content will accumulate here in time...
- Relativistic kinematics calculator and plotter: New and improved open source version available as of October 2025
- Tutorial on two body reaction kinematics: The new software is accompanied by an improved primer. This motivated me to learn mathML functionality in HTML5 and it is quite impressive. It is more tedious than LaTeX but the final result is better for web purposes. (Did I really just write that!?)
- Factorial approximation fun: recreational mathematics about the factorial and gamma functions
- Euler-Maclaurin formula: Derivation of a technique to evaluate infinite sums using integrals and derivatives, plus two examples of its use
- Calculating π: There are many ways to calculate π; this is the one that has yielded the most success for me by hand on a single sheet of paper.
