In the #2020s, several important #mathematical #formulas and #equations had been related to #socialnetworks and #socialgraphs. Some notable ones included the Erdős–Rényi #randomgraphmodel (G(n, p)), the Watts-Strogatz #smallworld #networkmodel, and the Barabási-Albert #preferential #attachmentmodel. These models had been used to explain the #emergence of specific #network properties, such as the small-world phenomenon, #scalefreeness, and clustering. https://parkhealth.io/Social+Graph

#SabineHossenfelder - Do #ComplexNumbers Exist?
"Do complex #Numbers exist or are they just a convenient, #MathematicalTool that we use in science? With the exception of #QuantumMechanics, it is easy to get rid of complex numbers. But can you do quantum mechanics without complex numbers? A recent paper says no, you can't."

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 #quadratic #equations 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.
> Mathematicians have long suspected that there exist initial conditions that cause the equations to break down. But they haven’t been able to prove it.
> In a preprint posted online last month, a pair of mathematicians has shown that a particular version of the Euler equations does indeed sometimes fail.
...
> Perhaps in some situations, the equations will proceed as expected, producing precise values for the state of the fluid at any given moment, only for one of those values to suddenly skyrocket to infinity. 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.
