comment How to tell whether a curve has a regular parametrization?
@Winther what do you mean by "if $\tau$ is a valid parametrization"? How can I tell whether it is a valid parametrization?

comment “Immediate” Applications of Differential Geometry
Isn't this the Borsuk-Ulam theorem? It is a topological theorem, I think it is more related to topology than to geometry.

Just to give some intuition: person A holds two knives such that the value between them is exactly $p$. The function $s(x)$ is the location of the second knife, when the first knife is at $x$. The function $\psi(x)$ is the value of person B for the piece between the knives, when the first knife is at $x$.

@DanielFischer They are non-negative. If this helps, it can also be assumed that they are positive.
