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

(Hmm, you might need 20 rep to use chat, or else you can ping me and I'll see if I can get you into a room.)

I'm not sure how much this should be on topic here, and I'm reasonably sure it won't be on topic at Academia. That said, this is the type of thing that would be great for chat if nowhere else.

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.

comment What mechanism is responsible for the creation of these dunes on Comet 67P/Churyumov-Gerasimenko?
Note to potential answerers who assume, like I originally did, that this is sand: It was pointed out to me that we have observed other bodies to consist of larger rock fragments (think fist-sized stones, I'll see if I can dig up a reference), and at this resolution that would look the same as sand. So these may be large pebble dunes rather than sand dunes.

comment Is any energy required to deflect an asteroid, with force always perpendicular to its trajectory?
I'm confused. You talk about straight lines and lack of gravity, then you talk about centripetal forces. Which is it?
