@matildalove@wetdry.world @rgarner@mastodon.social We've clearly read the same bash.org thread...
It's always a marvel to me,
For a pendulum hanging quite free,
Each tick and each tock of a grandfather clock
Is 2Pi(sqrt(L/g)).
I still mention this to students at that level (even though it's an approximation).
A mosquito was heard to exclaim,
"A chemist has poisoned my brain!"
The cause of its sorrow
Was paradichloro-
Diphenyltrichloroethane
[EDIT: Corrected bracketing on 2Pi(sqrt(L/g)), thanks Anton]

@_thegeoff@mastodon.social @matildalove@wetdry.world @rgarner@mastodon.social I archived the top 50(?) or so on limerickdb before it was lost. I think my fave is A woman in liquor production Owns a still of exquisite construction The alcohol boils Through magnetic coils She says that it’s “proof by induction”

@_thegeoff@mastodon.social @matildalove@wetdry.world @rgarner@mastodon.social I think I remember the approximation comes from tan(x) is small for small angles?
