Computing the topological genus from a parametric function
Recall that the topological genus of a surface (or Euler characteristic) is (in essence) the number of its "holes." Thus the genus of a baseball is 0 while the genus of a donut or handled coffee cup is 1.
Is there a way to calculate the topological…

How can Mathematica be used to compute distance from a metric?
I have a metric:
$$g_{\mu\nu}=\begin{bmatrix}-c & 0 & 0 & 0\\0 & a(t) & 0 & 0\\0 & 0 & a(t)\space r & 0\\0 & 0 & 0 & a(t)\space r\space \sinθ\end{bmatrix}$$
Having the dimensions $(t, r, θ, \phi)$. It corresponds to this…
