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 What are the tidal effects of Io on Jupiter?
"But I think the effect is more complicated than that, affecting the isosurface of equipotential" -- honestly, altering the equipotential surface is all tides directly do. On Earth's oceans, the presence of the continents together with the thinness of the ocean hampers the response to this forcing, resulting in complex patterns as detailed here, but I can't see this mattering for Jupiter.

comment Ratio of two RMS values in recorded audio
Questions simply about volumes are certainly physics, though when you start mixing in human perception (dynamic range), this becomes less clear. For similar questions, note there is a sound design beta site that might be more appropriate.

I'm voting to close this question as off-topic because it is about the conventions employed in navigation, rather than about physics per se.

comment Is it possible that Mercury collided with Earth, thus creating the Moon?
@BowlOfRed Well, Mercury is easily tugged by the other planets. For example its orbit is precessing at a good fraction of a degree per century relative to an inertial frame. And it has been proposed that its orbital parameters vary chaotically on very short timescales (for example having no eccentricity some times).

comment Can the event horizon save conservation laws for black holes?
The information paradox is a lot more subtle than often presented. In particular, even if you can account for all the information at the end and the beginning of the process, I think there is an issue in the middle. Most of the Hawking radiation comes out at the end of the black hole's life, when the hole itself is already too small to contain much information. Perhaps someone can fill in the details in this line of thinking.

@wim Yes. I meant 11.
