It's something involving kinetic energy and light. I see Einstein's equation e=mc^2 there, so that's a large part of it. Gimme a bit, I'll try and decode it.
It's the potential energy of a free moving particle in a 3 D space. For clarity the h with a line through it means Planck's constant over 2 pi, Not 100% about the upside down triangle but I think its about The velocity ( like I said not too sure), the circle with a line through it means the angle of momentum, i is the moment of inertia and finally the fraction with the like curly 6's is a for of differentiation of angle of momentum with respect to time.
Nah, I gave up. The other guy had a lot more information. I had just assumed it was something about bullet impacts solely because it seems like something that'd be followed by "Too soon". But thank you.
