### Physics Equation

Post your favorite physics equation. It can be about anything just make sure you explain what the equation describes and who formulated it.

It suggests that if you have a thing and you group it together with another thing in such a way that combining them represents some sort of meaningfully significant new entity, then you can describe that new entity with a symbol that will describe the objects as a collection rather than singular entities.

Happy Quark you should get in touch with rexrino over at physicsforums. He had some disturbingly impressive insight about a formula similar to yours

My fav physics equation is

T=1/f

Where f= frequency
T= time for one cycle
