Bizarre/Interesting examples/stories told by teachers to keep you interested/make you remember something
Phew,

Quite a few slashes there. What I am getting at is that teachers will often give a story to try and help you remember a formula or keep you interested. Some are pretty cool.

Our physics teacher told us that you could shake down a lamppost if you shook it at is resonant frequency and kept going till it fell over. We tried this later at uni but it made far too much noise.

your physics teacher was an idiot
shake something hard enough for long enough and it will fall down

has fuck all to do with its resonant frequency, and even if it did, its resonant frequency is likely to be a lot higher than how fast drunk students can shake it.

I dunno
They're pretty long.
