- Gemstone based metamaterial. Gem-gum as an intentionally paradoxical concrete example of
a mechanical metamaterial with vastly different properties to the base material. With a catchy name. - The defining traits of gem-gum-tec. What gem, gum, and gem-gum refers to.
Gem-gum-tech also called "gem(stone) based APM" here.
⚠️ Related warning
Be aware that:
⚠️ Diamondoid nanoscale machinery is not at all jelly like floppy
as molecular dynamics simulations may misleadingly suggest.
This is NOT what "gum" in "gem-gum" refers to. High simulations speeds are to blame.
For details see: Misleading aspects in animations of diamondoid molecular machine elements
Actually at nominal proposed speeds (few mm/s)
nanomachinery bends and deflects LESS from machine motions
than even everyday metal macroscale machinery does.
That is due to the scaling law of same relative deflections across scales.
A better intuition: hyper-spring-steel, super-magnets, and sometimes giant forces, all at snail speed
