"Science fiction and science have always danced around each other. Science fiction is the subconscious of science."
- Greg Bear

Single Sheet Molecule  
  A counterfeit-proof way to output unique documents.  

The single sheet he held, and even the words and signatures upon it, were all integral parts of a single giant molecule which in itself was well-nigh indestructible and could not be in any way altered or tampered with short of outright destruction. As for destruction itself - Donal was quite sure that there was nothing aboard this ship that could in any way burn, shred, dissolve, or in any other fashion obliterate it.
From Dorsai!, by Gordon R. Dickson.
Published by Ace Books in 1960
