Thank you! I live in Boston and am a frequent visitor to the Museum of Science, which has a Foucault pendulum. I never truly grasped the explanation until reading your post.
Thanks. I found that explanation a long time ago in some remote corner of the internet... some Japanese website about Transformers and Decipticons as I recall.
Ages ago -- when the Internet was young -- I tried to put the explanation in the Foucaults article on Wikipedia... it lasted about 30 minutes before getting deleted and replaced with the usual trig stuff.

My one and only attempt to edit Wikipedia was to redact a statement on the article about the Semantic Web that had recently been changed to note that someone named Dr. Foch was attempting to weaponize the semantic web in support of a Chinese takeover of the world. My edit was immediately removed for not having a valid reference...nevermind that the original note didn't either.
