Ask HN: Any place having all science and maths equations and implementations?

[NoelJacob]

Is there anywhere containing all the standard equations from maths, physics, etc like Pythagoras, Orbital lifetime, etc? I only need the ones that are feasible to compute on a desktop PC without taking more than an hour at most and isn't too specialised.

I don't know if it's possible to find but ideally I would like a function for solving each equation (a, b, c) = fn(x, y, z). Even if implementation isn't available at least the equations would be good.

Why? Curiosity? You want to implement a universe simulator? Studding?

The list is too wide and too difficult to use without understanding them. Wolfram Alpha (as suggested by a sibling comment) is quite good and they have a lot of docs. Wikipedia can help too. There are a fwe additional sites.

But without understanding "why" it's difficult to give more personalized advice.
