“Necessity is the Mother of Invention.” – Plato


Don’t know who Plato is?

You should. See: https://en.wikipedia.org/wiki/Plato

A need or problem encourages creative efforts to meet the need or solve the problem. This saying appears in the dialogue Republic, by the ancient Greek philosopher Plato.

So, what is the need to solve the problem of a Rubic’s Cube?


Aren’t other things to do that are more entertaining?
