Today I Learnt....

E = mc^2 is not the full equation...

this is the simplified form for the particles which doesn't have any momentum

actual equation shown in the image attached

Doesn’t look correct. Reason- p is mass * velocity. So for anything moving at the speed of light the equation becomes, E=1.414mc2 🧐

Any physicists in the house to explain this?

It doesn’t work like that. mc^2 is the static energy equivalent for mass m. So basically if a mass m is not moving and completely annihilate to energy then energy equivalent to mc^2 will be released. But if the same mass is moving with some velocity then what op is saying is correct.

That’s fine. I’m talking about a situation where the mass is moving. Will the equation yield the multiple of 1.414 if speed is equal to speed of light?

Rather for any moving mass, the multiple would be greater than 1. The velocity can be represented as a % of c and the equation will become E= sqrt(1+x%)mc2

[Thread] What is your favourite math equation?

TLDR: I was reading up on the Navier Stokes equations today and it is so elegant that it might be my favourite math equation.

Equation 1: ∇u = 0 (conservation of mass) states that the divergence of the velocity vector u is zero, mea...

Boss' call saved my ass yesterday

Was at my relatives' place yesterday for Rakshabandhan.

We were all sitting down after lunch, casually chatting over tea. My cousin is prepping for JEE (two years of coaching plus school). We're on good terms; he looks up to me in terms...
