I'm applying to some schools that have a February 1st deadline. I'm not sure if I will do too well this semester. Let's say it moves me from a 3.7 to a 3.6. Would sending my transcript now before the semester ends be advantageous or would it just look dubious? Would they request a more recent...

I have been doing pendulum problems lately, and I have found 2 different formulations for potential energy of a pendulum. U=mgl(1-cos(Θ)) and U=-mglcos(Θ) The first says U=0 when Θ=0 (at the bottom). The second has U=0 when Θ=π/2 (halfway to the top). Both give the same equation of motion...

Planetary geology, astrogeology, and geophysics come to mind. You will need more schooling, but you are probably best to use your geology knowledge in combination with physics or astronomy. Good luck!

I have some problems with your plan. You say you want to interested in computers, but don't want to go into computing because you wouldn't "make an impact." Read about Elon Musk. He started in computing, was very successful, and then made SpaceX. You cannot make an Aerospace start-up in the way...

Hi, I am a junior astrophysics undergraduate student and enjoy physics, but after researching astrophysics PhD's, I am having second thoughts about graduate school. My impression of physics graduate school right now is that you are paid what amounts to minimum wage to work 60 hours a week for...

Moo. Alright, well 1 last question: so when you multiply, you're adding a bunch of times and when you integrate you're finding the area, so conceptually what are you doing with the Ramanujan Summation?

Oh, never mind thanks for clearing it up for me, but I still don't quiet understand why it's negative n

I thought that too, but this guy pulled out some string theory textbook.

I've recently accepted (reluctantly) that 1+2+3+4+...=-1/12, but wouldn't that mean the limit as x→∞ of f(x)=x not be ∞ but some maybe negative number because if it were ∞ then 1+2+3+4+... should also be ∞. Also, do numbers get so positive they become negative lol.
