I am writing a little article about thought experiments through the history of physics (university level); more specifically, from the times of Thales of Miletus (~ ancient Greeks) to our day.
I want to cover as many as possible of them, and not just stick to the most famous ones as those of Einstein (for example).
I should point out that I have already searched on the internet (including this site), and already got a good number of them; but I want to be sure I have not overlooked any interesting thought experiment.
So my question is, does anybody know about any thought experiments that are not commonly known (even for a physics grad student with access to Google)? Thanks in advance!
Edit: Ok, main question could be too broad so I'll be more precise:
Do you know about any thought experiments (in physics) dated from before those of Galileo?
