  • Thanks for posting this!

  • Seems tetrahedra would have duality with two interlocked rings, maybe something like a di-quark, maybe not like a meson. If I were using a fluid dynamics model, it seems surface tension discontinuities would be a prominent phenonenon when it comes to representing binding energies at various scales

  • My first thought at the moment is why not go with octahedra (2^3 faces) instead of tetrahedra. It's just because I have this nucleon model based on thick tight borromeo rings that empasizes what I perceive as octaherally-arrayed cube-corner-reflector-like mixing zones, where an inter-nucleon reflection-conservative property is analogous to binding energy. Seeing a ring as a depth-gradient mirror helps with this idea. Maybe using octahedra makes no major difference, I can't be sure at this time.

  • Thanks for posting this video - I'm still going through Rovelli's book on QG, so still have much to learn. Surprised Lubos Motl hasn't spammed this video yet ;)

  • I believe this field of mathematics can be used to model turbulent fluids in 3 dimensions, along with other goodies found in Quantum gravity. Its amazing how similar fluid mechanics is to quantum gravity, just my opinion.

  • Thank you.

  • So most of it went right over my head because I'm not hip to the jargon, but I was curious about the 2D nature of space time at small scales. First how small is small? Much smaller than atomic scale I'm assuming. Second what effects would this have on particles/forces?

  • I think the scale would be close to Planck length (1.616x10^-35 m).
