If you need to solve symbolic problems in code, check out the complete guide for SymPy package I wrote ten pages on topics such as systems of , ordinary equations, , , equations, and Diophantine equations, and numerical solving. docs.sympy.org/dev/guides/solv

What I find interesting is: b^2 -4ac > 0 can be rewritten to say that the arithmetic mean of roots is > geometric mean. But what even IS geometric mean for two complex numbers?

This plane represents all possible with real coefficients.

The area in red is where both roots are real because the discriminant b^2 - 4ac is > 0. All the quadratics with imaginary roots lie inside the white region that's a parabola itself.

Interesting.

> One of the central problems in fluid dynamics is to figure out if the [Euler] equations ever fail, outputting nonsensical values that render them unable to predict a fluid’s future states.

At that point, the Euler equations are said to give rise to a “singularity” — or, more dramatically, to “blow up.”
> Once they hit that singularity, the equations will no longer be able to compute the fluid’s flow.

Very important and interesting work, if you're a mathematician, a physicist or an engineer that has ever 'crashed' with Euler/Navier-Stokes equations.

Can you please explain to a 14, 17 and 48 year old the reason why taking the square root of both sides does not work?
