Kaehler bracket

Kaehler brackets are (usually small) structural crystolecule elements made from gemstone-like compounds
that have as their internal structure not a nicely ordered lattice
but rather a glassy amorphous like structure that was computer optimized
to approximate a certain ideally desired geometric alignment.

Kaehler brackets fing mention in Nanosystems.

Avoiding high internal stresses and strains

Avoiding high internal tensions will usually be desired to:

• retain full mechanical strength
• avoid fire hazard or even explosion hazard

Size and search space

The bigger the bracket the more accurate a desired alignement can be approximated.
The search-space quickly becomes hyper gigantic though.
Quantum computers could be used to find optimal atomic arrangements for desired geometries.

Going to the extreme

Even if thermal motions are bigger than the achieved accuracy over large scales (macroscale) that can average out.
Gravitational detectors e.g. can detect distances far below the diameter of an atomic core.
