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 How can laser interferomerty be used to measure path difference smaller than wavelength of laser light?
Have you ever seen the fringes from an interferometer? There's nothing stopping you from measuring a fraction of a fringe...

comment What happens to sound at speeds greater than mach 1?
I'm really confused by the close votes here. The sound is reversed, and the OP seems to understand this better than most users on this site.

comment Difference between Enzo & Gadget astronomy simulation codes
Ah that too. To be honest, I don't use either code (being an Athena dev myself), so I'm just going off a quick glance at their webpages.

comment Circle becomes Sphere in 3d?
In particular, that scene in the movie was all about how we normally draw wormholes as circles, since we suppress one dimension for convenience when using 2D paper. The circle $\to$ sphere conversion is just undoing that simplification. If we understood some other 3D $\to$ 2D process at work, we would undo it in some other way.

comment Book suggestion for introductory plasma physics
Note there are (at least) two main branches of plasma physics books these days: astrophysical plasmas and fusion plasmas. You kind of have to decide which application you want the theory grounded in.
