There is a great Greek paradox/puzzle called the Ship of Theseus. There are multiple versions and derivations to it. My favorite version is as follows (highly watered down). Theseus bought a new ship. Each day he replaced one part of the ship.…

The world of systems is very wide and deep, and this column can’t be perfect and all-encompassing. My goal here is to emphasize that solutions based on incomplete models lead to incomplete solutions. I’m not calling them incorrect solutions, just…

As our new year unfolds, I wanted to write an article to remind myself of three pieces of advice. They are from Epictetus (55–135 AD), Marcus Aurelius (121–180 AD), and George Pólya (1887–1985). Epictetus and Aurelius are two famous Stoic…
