What is a circle? complete, more accurate answer Jun7 answered Geometric Definitions: What is a straight line? What is a circle? Jun7 comment Non-existence of irrational numbers? It's a little bit like the question of whether the area of a surface is different when you bend it: Is the area larger on the convex side? One thinks of the surface as infinitely thin, but such a notion is useless for edge-cases like the above. If there isn't a difference, then there isn't even a notion of "curved surface". Jun7 comment Non-existence of irrational numbers? Your example may not actually be perfectly correct. The issue involves the notion of a surface and what it means to "cut". You would require an beyond infinitely-sharp cutters, and they cannot be conceived. For this issue of irrational vs. indeterminate rational rests on the distinction of the real vs. idealism. Jun7 awarded Supporter Jun7 comment How far can one get in analysis without leaving $\mathbb{Q}$? See also "Is the diagonal of the unit square truly irrational?" for a geometric quasi-proof for the algebraist. There it's shown that it is not merely a notion of linguistics and terms. Jun7 comment Is a transcendental number necessarily irrational? "Polynomials have precise definitions" is somewhat a matter of convention and habit. Beyond that there is only logical consistency. The question is whether these definitions stand in the light of new data. Please see the reference to geometry in the question "Is the diagonal of a square truly irrational?" Jun7 awarded Commentator Jun7 comment Is a transcendental number necessarily irrational? That doesn't look like a polynomial, only a "nomial". But this is where terminology becomes paramount. One can't argue on the grounds of reason here, because it involves definitions. Jun7 comment Is a transcendental number necessarily irrational? Zero is not a root. Is it transcendental? I've started a little hullabaloo over at "Is the diagonal of a square truly irrational?" if you want to join in.

But, technically, dripping water probably can't -- at least at the place where it turns chaotic.
