- Perhaps Karl Popper should study theories of thinking, rather than
- physics. The purpose of such simple thought experiments is not to
- embody the exact uncertainty principle within a thought experiment.
- Rather, the point is to fit the concept naturally into one's own
- conceptual framework, so that it can be mentally manipulated and applied
- with ease.
-
- I.e., these minimal conceptions allow one to use the
- tool readily. Once you've discovered a use, then you can go back
- and check that you didn't missapply. The purpose of these minimal
- conceptions is _creative thought_, not _rigorous thought_.
-
- I think Popper should not be telling physicists how to think
- about things, seeing as he is a philosopher, and has not done
- any creative work in theoretical physics
- (or thinking skills, apparently)
