"It is change ... that is the dominant factor in society today... the world as it will be. This means that ... every man must take on a science fictional way of thinking.""
- Isaac Asimov

Chalf-Memory Stick  
  Device that organizes special dust in the shape of words and symbols.  

This is what you use on your chalf; it's kind of like printing carbon powder onto paper - without the paper.

Watt pushed himself back from his desk, eyeing the powder with suspicion. He took a cautious sniff, smelled chalf, the quick-scribe powder. Still...

"So scribe it," Watt said.

Concealing his elation, McKie held a chalf-memory stick over the dusted surface. A broken circle with arrows pointing to a right-hand flow appeared in the chalf.
