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

comment Why does my eardrum feel strange inside a car?
Any answers here can only be wild guesses, because there isn't enough information to go on. Did this only happen while the car was moving? How fast? What was the terrain? The weather? Were you driving through a tornado? Did you sneeze particularly hard? Did the feeling go away upon swallowing? Were any windows open?

comment Wouldn't angular momentum of a binary star system decrease?
The OP seems to have had a different question in mind than the one originally asked, but +1 for the answer to what was originally written.

comment How is the Plane of the Solar System oriented to the Sun's motion through space?
@JohnRennie Well there is at least one other obvious interpretation, as has partially been answered already: physics.stackexchange.com/questions/2582/the-galactic-plane

Hi there, and welcome to Physics Stackexchange! Just so you know, we implement Latex-style math formatting on this site. (Detailed guide here)

comment Velocity distribution in Plummer's models and others mass distributions
+1 for the nice summary. I'll mention that an optimally chosen range will get rejection sampling to work a bit over 46% of the time in this case, so I don't think it's too bad. It's the approach used by Aarseth, Henon, and Wielen, whose half-page appendix covers the initialization problem quite well.

revised Why do rocket engines have a throat?
motors are not the same as engines; fun fact: unwieldy images can be made smaller by changing the link

comment Integral form of Gauss's law for magnetism from Stokes' theorem?
Huh - I've never heard it called "Gauss's Law for magnetism," and it's one of the most referenced equations in my field.

comment Does the Sun produce audible sound?
While the p-modes are pressure waves just like normal acoustic oscillations, their frequencies are something like 3 mHz, so they don't really correspond to "sound" in the colloquial sense.

comment Do Pulsar Stars produce sound?
The latest installment in our "natural sounds in space" series, which includes supernovae, black holes, and the Sun.

comment How is gravity consistent when you split an object into multiple pieces?
@user49685 For yet another proof, why not go back to original sources: Newton's Principia proves the result for spheres in detail (using the admittedly underdeveloped mathematical language of the day).

comment Can we break the Shannon capacity?
I agree this is not so much about physics, but the math underlying signal processing. At the very least, terms like "slot" and "symbol" would need to be better defined here to make sense of the question, whereas they are presumably understood in the signal processing community.
