For any potential attendees of my "Wave Motion" course.

"Water waves are usually used as an example of waves in elementary courses, but as Feynman said "they are the worst possible example, because they are in no respect like sound and light; they have all the complications that waves can have”."

That's what makes them fun ...... but also why we won't begin with water waves.

I found this on my office chalkboard this morning, thanks to +Ryan Grover. Attempt to reason through it if you must. #mathed
