Excercise: Derive the rotation rate of a Foucault pendulum
at an arbitrary latitude, inertially, without using Coriolis forces.

Anecdote, FYA. Foucault himself could do it, and did it.
He gave the correct result, in an off-hand way, without derivation.
This drove the leading lights of Parisian mathematics crazy.
It annoyed them greatly that a mere outsider, one they loked down upon,
not a mathematician, did it, as if it were obvious,
while they had to struggle.
It took some of them months to get it too.

nonsense. That's turbulence, large scale.
