Also...
"Amorphous" -- is just another way of saying that the crystal patterns contain shorter runs within the whole of the material... in other words, you can have differing crystal patterns which take up smaller amounts of space -- than the whole of the structure...
That sort of brings us to Level 2...
Level 2 is not just understanding metals as crystals, but (potentially) as crystals containing runs of various crystal structures, which could be the same crystal pattern, and could be different crystal patterns -- interrupted by fractures.
That brings us to Level 3:
Level 3 is sort of understanding Crystals -- as Fractals, that is, as "nested containers", that is, crystals themselves -- may contain one or more repeating patterns much in the same way that the larger structure contains one or more repeating groups of crystals...
Anyway, my point is, there's a lot more research to be done here... that and certain words like "amorphous" can unintentionally obscure the deeper pattern... or broken patterns, as the case can be...
Level 4 understanding: Broken patterns -- are indeed broken at one level(!) -- but they can be part of a "higher order" (unseen) pattern... a higher-order "pattern-breaker pattern".
Which should be discoverable using higher-order (higher dimensionality) math...
As I said... more research needs to be done here...
