- CPhO translation [quit because it's a serious waste of my time]
I worked on the translations for about twenty years worth of problems from the Chinese Physics olympiad, which is currently available online in Chinese only.
- Atmospheric refraction
How much later does the sun set due to the refraction of light in the atmosphere?
And a generalization to times other than sunset
some screwing around with 3-body, equal mass simulation, a short comparison of various numerical integration methods
- Bucket problem
What shape does light form on the bottom of a bucket? Some various approaches to this problem, using computer and analytical methods
Here is my favorite physics video: Rotating textbook
. It humbled (humbles) me!
