Question about Schrodinger equation

[3m0k177y]

Ok, I understand the Schrödinger equation for the most part, the thing is though, I don't understand what ∂ means...
In the equation:(∂^2ψ/∂x^2)+8(pi)m/h^2(E-V)ψ=0
It pops up two times. The rest of the equation is kinda self explanatory, but I don't know what on Earth ∂ means
please, tell me, the ignorance is killing me.

Partial derivative.
The Schrödinger equation is a partial differential equation (PDE).
As for what it means, I guess I'll leave it to you to explore yourself :)

here is a good description of the equation

Partial derivative. Do you know calculus? Its part of calculus, multivariable that is.

Partial derivative i.e. if ψ is a function of two variables x and y, then it will be differentiated only with respect to x and the part of the function consisting of variable y will be treated as a constant. You may need to read up on it to fully grasp the concept of partial derivatives
