I, as a programmer, asked professor: What is a monad?
He replied: A monad is an old russian towel, so the monad might have evolved into a soprano, but a soprano is a woman who sings on the stage.
I was confused by this answer, I did not know what a monad is. But as he explained that a monad is an old russian towel, I noticed that there was an obvious connection between the word monad and the word monastery, where people lived in seclusion, and meditated on the topic of the meaning of life.
I did not have an idea what a monad is. So I went to the internet to look for the meaning of the word "monad". I had an impression that "monad" is the highest abstraction of "bead". Beads were the reason that motivated us to invent knots, but later on we learned how to use monads to program.
