Are all measurements in the real world just approximations of the ideal?

This was more of a mathematical question, but because it’s closed and people say it’s philosophical I post it here: Someone tells you “my pen is 9 cm long”. How can that be? Can you really have a pen ...

What are the ontological implications of that “the universe is not locally real” in quantum mechanics?

Is there any “stability metric” for scientific fields?

Is there any attempt to gauge how quickly a scientific field overturns its own claims/findings; ie an evaluation of if the fields’ findings have what degree of longevity? It could compare fields as ...

Is there "empirical" distance without "mathematical" distance?

Mathematicians since antiquity have been thinking about length and angle, including doing things with straight-edges, rulers, compasses, and protractors. Fast-forward to modern physics, and you'll see ...

What is the difference between Zeno's "Dichotomy" and Richardson's "Coast of England" paradox?

We assume, though I believe it can be debated, that Zeno's "Dichotomy" paradox is apparently "unreal." We can treat any given distance as the sum of an infinite regress of smaller ...
