Fang Fang – Quasicrystals, Penrose Tilings and Ribbon Dynamics.

Quantum Gravity Research | August 15, 2025



Quantum Gravity Research (QGR) head scientist Dr. Fang Fang introduces the basic concepts of quasicrystals (QC), a typical 2D QC called the Penrose Tiling (PT), and Ribbon Dynamics in PT’s – dynamic phason code in PT using its ribbons.

Present: Quantum Gravity Research scientists Klee Irwin (director,) Raymond Aschheim, Amrik Sen, Aaron Marchant, Daniel Woolridge, Russ Gries, Arindom Saha, Dugan Hammock.

    Does the fact that the D vertex configuration does not force any other tiles not imply that no tile of the D vertex configuration can be forced?

    I really have ended up in a youtube rabbit hole. It started when veritasium mentioned that that its possible for verteces in a quasi crystal to provide enough constraint for the tiling to work globally but penrose tilings, as far as i knew, couldnt be made with tiles piece by piece with only local rules so that it would globally work. Honestly im still confused but this was somewhat informative even if im not in this field at all as an unemployed engineer

    One explanation of the answer to the 1:05:00 question:

    If A is in the empire of vertex type T, it's forced by T, and if B is in the empire of A, it's forced by A, and thus by T.

    So if B is in the empire of anything in T's empire, it's in T's empire.

    Is there an 8-dimensional "engine" behind our universe? Join Marion Kerr on a fun, visually exciting journey as she explores a mysterious, highly complex structure known simply as 'E8'–a weird, 8-dimensional object that for some, strange reason, appears to encode within it all of the particles and forces of our 3-dimensional universe.
