A funny story where annoyingly physics gets in the way
of Gedankenexperiments. Two professors clash about whether
Zenos paradox is for real: Can a frog which makes jumps
of 1, 1/2, 1/4, 1/8... really reach 2? Math says yes,
but they agree to solve it experimentally. One prof
maliciously puts the other in the companionsship of
the frog. Now *he* must run too from the doomsday device
which also halves his size which each step.
It ends obviously - as soon as he is smaller than atoms,
he passes easily through the backdoor of the contraption,
and out of the shrinking field, where he regrows.
The most funny thing is the end: The prof is not angry
about the other playing such a prank on him, but about
Nature which ruined the experimental setup with her
dreckeffekts.
