Group theory and crystallograpy without either word? I suppose I can look at this as an extension of group theory to glassy and partial.domains, but it doesn't appear to offer much more.

Columnar basalt formation has been understood for a long time, I really don't understand what this explained that wasn't already known?

It doesn't even explain it particularly well. The reference to a taco cart was unexpected; it wasn't necessary, but an interesting literary device, I suppose. I just feel a good editor could have made it a better explainer. It's all over the place.
