More epistemological/metaphysical than scientific, but a good limerick told by Alan Watts:
There was a young man who said Though
It seems that I know that I know,
What I would like to see is the “I” that knows me
When I know that I know that I know.
Higgledy Piggledy, Herr Werner Heisenberg
Cried out “Judge, it just isn’t fair!
That I was speeding is unascertainable,
And if I was, then I can’t have been there!”
(This was an Omni competition winner about a thousand years ago and it stuck with me.)
A manager, mechanical engineer, and computer programmer are driving through Austin, when suddenly the brakes fail as they’re descending a hill! After successfully coming to a stop, they get out and wonder wtf just happened.
The Manager says, “I’ll form a committee to investigate the incident!”
The ME says, “Hang on, I’ve got a screwdriver - I can probably fix it.”
The programmer says, “I dunno, I think we should push it back up to the top of the hill and see if it does that again.”
