I was about to answer this, you did it first mein nigger

Brainlet reporting in, is here the brainlet club?

Is there a variational principle (like least action) that recover Schrödingers equation?

> I am not exactly comfortable with the way he treats Liebniz notation as a fraction either.

That's because OP did it in a moronic handwavy style, however it's possible to show OPs identity is true:
[math]\frac{d^2 y}{dx^2}=f(y)[\math]
A simples substation of [math]\frac{dx}{dy}=\dot{y}] will lead to
[math]\frac{d \dot{y}}{dx}=f(y)[/math]
[math]\frac{d \dot{y}}{dy} \frac{dy}{dx} =f(y)[/math]

Which as you can see will lead to OPs result. As I said, this a VERY famous did equation in physics, in fact they're equations of motion for an harmonic oscillator if you define [math]f(y)=-ky[/math], where k is a positive real number.

So, yes OPs identity is true, and I have to recognize his skills on problem solving (although he manipulates the equation in a WRONG hand wavy way). But whatever Fourier also lacked formalism in his work. In the end OP is a moron for thinking he discovered something new and also an idiot for lack of formalism.

Good advice, I'm geniuses though

So I saw a thread like that this week and I think it was actually a good idea.
