Thank you, this video made it instantly understandable.

The visualization of the paths of the vortex rings looks mimetically like electron orbitals

  That's because the orbitals are the consequence of spherical harmonic interference. https://en.wikipedia.org/wiki/Spherical_harmonics https://en.wikipedia.org/wiki/Spherical_harmonics

    Does that mean you can shoot 8 electrons and create a contained ball of electromagnetic turbulence?

      Electrons would just strongly scatter. You would probably need a charge distribution that produces an EM field which looks like the vortex rings. I forget how the analogy for fluid systems works, I think you have to make Poynting vector <-> pressure vector for the math to look similar? Not sure if that would work exactly but you can definitely make a ball of EM turbulence.

Amazing demonstration of yet another example of things that just work better in 3D. Seeing the 3D simulation through a 2D video on a 2D screen works to get the point across but it's so much better with the affordances of XR. I am hopeful it will become standard to publish to that medium in the near future so you can just click on a web link to see this whole system floating around you at whatever scale and perspective you choose. That to me would really help your ability to use others minds to reason about a problem, as you put it so well.

Fascinating! I wonder if this explains ball lightning?

Thanks for sharing! Amazing video... Also reminds me of this classic - Schrodinger's smoke from SIGGRAPH 2016: https://www.youtube.com/watch?v=5C9BLAXCe1I https://www.youtube.com/watch?v=5C9BLAXCe1I

Did they also try repeatedly colliding 2 vortex rings? That may make more sense of what parameter changes do (?)
