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.

Hi Sayan Datta, and welcome to Physics Stackexchange! Note that we support LaTeX-style MathJax for math formatting. You can click "edit" to see how I formatted your equations if you're not familiar with the syntax.

comment What happens to the skin when UV light burn you at the beach?
UV light is energetic enough to break chemical bonds (a topic better suited for chemistry than physics), and the response of your skin is very much a question for biology, not physics.

comment What speeds are “fast” enough for one to need the relativistic velocity addition formula?
I've heard the centimeter-level precision claim too, though I can't fathom how they deal with the varying light travel time though a dynamical atmosphere to the point where GR becomes relevant.

comment Number of significant figures
Nitpick: In a digital instrument where there is no doubt the displayed digits are correct, the discretization error is $1/\sqrt{12}$ times the scale step, not $1/2$, if you're going for the standard deviation.
