(wiki-TODO: Cover the below points)
- Add a basic explanation
- Show and explain basics (retractile cascades - collect all relevant images here)
- Show and explain Robert Baruchs reversible logic latch memory cell (from links below)
- Different designs polyyne rods vs crystolecule rods
- Considerations regarding friction/dissipation and radiation hardness

Relation to reversible computing
Rod logic seems to lend itself to reversible computing in an easy to understand/comprehend way.
As such it may be a good didactic tool for teaching reversible computing principles.

- Crystolecule rods
- Zuse Z1 - not rod logic but reciprocative logic
(depending on friction & gravity thus not 1:1 usable for nanoscale) - Buckling logic

Slide 28 here on needed sequence for reversible state transitions for a memory latch:

(wiki-TODO: Add this highly relevant slide as picture here under assumption of fair use. Also on pages reversible logic pages and perhaps dissipation sharing.)

Rod logic (&bucking logic) for reversible mechanical computation:
Robert C. Baruchs old work on rod logic
Especially interesting here is a latching memory cell that
seems simpler and more natural than the one presented in the book Nanosystems.
