C/Fe
Entering The Gaz Giant

“- See fee? What’s that?
– Just the chemical symbols for the elements carbon and iron, Elijah.
Carbon is the basis of human life and iron of robot life. It becomes easy
to speak of C/Fe when you wish to express a culture that combines the
best of the two on an equal but parallel basis.
– See fee. Do you write it with a hyphen? Or how?
– No, Elijah. A diagonal line between the two is the accepted way.
It symbolizes neither one nor the other, but a mixture of the two,
without priority.”
(The Caves of Steel, Isaac Asimov)
