I am a graduate student studying astrophysics at Princeton. I received my bachelor's in physics and mathematics from Caltech (2011).

comment Notation regarding the continuity equation for conservation of mass
Mathjax supports \iint and \oint but not \oiint. In a pinch there's \unicode{x222F} for $\unicode{x222F}$, but it doesn't scale beyond inline math.

comment Solving ODE with negative expansion power series
@dingo_d Well, Math Overflow is generally only for research-level math. If your question is just needing an application of well-known ODE theory, it belongs on Math Stackexchange. If it calls upon physical principles in some meaningful way (beyond just "this came up while doing physics"), then it is okay here. But I doubt it will be particularly well-received on Math Overflow. In general, though, if you feel the question should be moved, you can ping a moderator and request they migrate it for you, to avoid cross-site duplication.

comment Analytical Solution for Elastic Bar under applied end velocity
Existence of solutions sounds more like a math topic, unless you want to know if the setup is physically reasonable enough to admit a solution. I suggest migrating to mathematics, though in that case the users there should take into account that the word "analytical" here probably means "in terms of common functions" rather than simply "converges to its Taylor series."

comment Uniqueness of the vector in $\mathbb{R}^n$ specified by the curl, divergence and the normal component
Though no doubt used in physics a lot, this is most certainly a pure math question (with a pure math answer).

comment Mathematicians conceived of black holes long before astronomers actually found any?How?
A word of caution about the looseness of that claim: Most everyone involved in developing the theory of black holes would be described primarily as a theoretical physicist/astrophysicist, not a mathematician. You could ask how does any theorist make predictions prior to having observations, but that's just what a *pre*diction is, and it's exactly what theoretical scientists do all day long.

comment Solving to get free falling coordinate as function of arbitrary coordinate
Should that be $\partial x^\mu$ rather than $\partial x^\lambda$ on the left?
