Re: [Phys-L] To gal or not to Gal.



Was this a real experiment, or a thought experiment ( = Gedankenexperiment) ?

Confusedly,

When I was in Pisa many years ago I decided to do a gedanken experiment.

I dropped a 1.000 Lire coin and a 1,000 Lira note at the same time.

Unfortunately, I forgot to station a grad student to make observations.

It could in fact be just the product of my overactive imagination.

(Or it might well have the sort of thing that Isaac Asimov would have
included in any of his many tomes that I absorbed as a child.)

I briefly reviewed the discussions of the Two New Sciences, but I
found no description with this arrangement, so I expect that it
occurred in some earlier, less digested version of the study of motion?
