comment Motivation of the Gaussian Integral
This is an interesting answer. However, it is not clear to me why $p(x)\Delta x$ is the probability of landing in the vertical strip of size $\Delta x$. What is the justification for this?

comment Functions as integrals of basis functions
I know about this theory. However, it doesn't yield the classical Fourier transform though (where thinkings happen in $L^1(\mathbf R)$.

comment Questions about boundary faces of simplices and triangulations
@wckronholm I understand what you meant to say now, that is that every point of a simplex is an interior point of one of its faces. Let me think about what I can do with that.

@wckronholm That cannot be true since two subsimplices may share a face.

comment Questions about boundary faces of simplices and triangulations
@Joseph A triangulation of an $n$-dimensional simplex $S$ is a finite collection of $n$-simplices, called the subsimplices of the triangulation, whose union equals S and such that the intersection of any two of them is a common face.
