What are…monads?

Goal.
Explaining basics concepts of category theory in an intuitive way.

This time.
What are…monads? Or: The natural numbers as functors.

Disclaimer.
Nobody is perfect, and I might have said something silly. If there is any doubt, then please check the references.

Disclaimer.
The distinction between “large classes” and “small classes (sets)” turns out is crucial for many categorical considerations, but somehow makes the language more cumbersome without too much gain imho. So I will strategically ignore all set-theoretical issues.

Nonsense.
Of course I messed up my guess how old the Ishango bone is…

Slides.

Also monads (and not unrelated).

Your videos are much appreciated! I’m hoping you could comment next on commonad, adjunction between monads, and triple adjunctions in the coming presentations.

For example (T(X)) and (T(T(X))) Are the parentheses the wrappings of the Monad? Is the Monad nested?
