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

My primary interest is in general relativistic magnetohydrodynamics simulations of black hole accretion.

comment Manager for results of physical simulations
You know, as projects scale up the work required to set up the software pipeline becomes comparable to the work needed to write the simulation code/design the telescope/build the particle collider. And alas these are usually quite specialized; I'm not aware of any "pipeline infrastructures" out there.

comment How do control rods work?
In case the terminology isn't clear to someone not in the field, I'd add that "thermal" means having a Maxwellian distribution of speeds, usually with a temperature of something room temperature. That is, the gas of free neutrons approaches thermodynamic equilibrium with everything else in the reactor, in this case by slowing down ("thermal" does not always mean "hot").

comment Measuring small amounts of lift in a wind tunnel
For the record, I think off-topic by way of engineering is meant to exclude "what is the most cost-effective way to manufacture this?" questions, not "how do I perform a physical measurement?" questions.

comment Calculating vector to aim for moving asteroid (3D asteroid game)
@Bradley My (4) is just a way of writing your statement "our ship can shoot bullets, the speed of which is known" -- I write that known speed as $v$, and in my notation the vector $\dot{\mathbf{A}} = (\dot{A}_x, \dot{A}_y, \dot{A}_z)$ is just the velocity vector for the bullet. $\lVert \dot{\mathbf{A}} \rVert = v$ is the fundamental constraint equation, but this is easier to write by squaring both sides.
