Morphological logic (gates)

« previous post | next post »

A recent xkcd:

Important logical relations left out:

"If not now, when?"
"If not me, who?"

(Or maybe generalized as "If not X, WH?")

    "If not now, when" can easily be schematized thusly: https://depositphotos.com/316977024/stock-illustration-kabbalah-symbol-sephirot-and-tree.html

    In high school, my friend Jamie Large showed the WAS gate, which is connected to 120 V AC.

    Some of the problems in my college textbook included the BOMB gate (which would explode if it encountered certain input patterns) and the LEMON gate (which only worked predictably on certain input combinations).

    Some other real variants are open-collector gates (which could only pull the output down, but couldn't drive it up), and tri-state gates (one input of which caused the output to float).
