Abstract

Here is your narration for today's MERLIN SCIENCE video. --- Today's finding is this: the same number that forbids five-fold symmetry in a periodic crystal is the exact key that unlocks it in a higher dimension, meaning the crystallographic restriction theorem is not a law of nature, but a limitation of your dimensional embedding. The problem this touches is the old puzzle of quasicrystals. For decades, the crystallographic restriction theorem seemed absolute. It says that in a periodic lattice, a rotation is only allowed if its trace is an integer. For a five-fold rotation, that trace is two times the cosine of seventy-two degrees, which is exactly phi-inverse, zero point six one eight. That is not an integer, so five-fold symmetry is forbidden in three dimensions. Yet Shechtman found it. The field needed a mechanism, not an excuse. Here is the mechanism, and you can check every step. In a periodic lattice, the trace must be an integer because the lattice vectors must map to integ Author: Andrew Stewart Caldin, Independent Researcher, UK.
