Derivative

Abstract Definition: For any smooth and differentiable mapping f:R->R, the derivative is an operator d/dx that takes f to df/dx, defined by the limit of the difference quotient f(x+h)-f(x)/h as h approaches 0.

Geometric Definition: The slope of the tangent line at any point of the graph of a function.
The Derivative of x^2 is 2x.

Spin

In Quantum Physics, spin is the intrinsic angular momentum associated to Elementary Particles. It is the quantum mechanical analogue of angular momentum.
Some guy : Yo g, can you tell me what people mean by "spin"?

Nerd : Oh it's just a thing elementary particles have. For example, Quark has a Spin of 1/2.
