Jaime, thanks for writing an excellent article. It’s clear enough that even a layperson can follow it with ease, yet you don’t “dumb down” by removing the key formulae (which, fortunately, are quite straightforward to follow). I also think your use of visualization makes it easier for people who haven’t done any geometry or trig for a while.

Anyone who enjoys my articles here on Medium may be interested in my books Why Democracy Failed and The Praying Ape, both available from Amazon.
