It’s been a while since my last Sidebands post. That’s partly because I’ve been working on a project that I’m sure will become a multi-post series and thought it would be nice to start with #81. But I’m not done (or actually started on the writing) yet, and this one has also been lurking for a while.
Essentially, I needed to figure out how to join a cone to a sphere in a seamless way (as in the picture here). This requires the sides of the cone meet the sphere at a tangent point.
It’s yet another case of actually needing the trigonometry I learned in school.


Back in 2021 I got tired of having lots of supposed subscribers but almost no views (let alone engagement). 
Maybe this is on me; maybe I lack proficiency with English grammar. That’s always possible. I certainly have no pretension of being a grammarian, but I like to believe I have some grasp of it. In any event, lately I’ve found myself bemused by the Microsoft grammarian embedded in Windows™.
