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 Why is the wave equation so pervasive?
In a very real sense nature only evolves hyperbolic equations; elliptic and parabolic equations are what we get when we make various approximations that change the question from "how does this evolve?" to "what does this evolve into?" or "approximately how does this evolve?" Even then, though, the wave equation isn't the only hyperbolic equation out there. Conservation laws (e.g. $\nabla_\mu T^{\mu\nu} = 0$) naturally beget first-order hyperbolic systems.

comment How can the Hubble telescope see the light from galaxies that are millions of light years distant?
Echoing Rob here. This question has nothing whatsoever to do with the marked duplicate.

comment How does the strength of gravity affect human walking speed?
Indeed to zeroth order walking is just falling forward as an inverted pendulum. Higher $g$ means shorter period, which equates to moving faster. Anything more sophisticated is no longer physics but biology.
