This piece sounds impressive until I ask you what the equatorial speed
of the Earth is and,giving the incorrect answer,you set off a chain
reaction which leads to some really nasty conclusions.

Whether one is measuring the effect of centrifugal force at the
Earth's equator on the period of a pendulum clock, or the even more
subtle relativistic effects, we find that only the 23 hour, 56 minute,
and 4 second period for the Earth's rotation gives the right answers.

Now, I'll agree that a Schwarzschild metric tensor can be pretty nasty
to someone who doesn't even understand basic algebra, this stuff isn't
nasty in the sense you're using the term.
