> Pythagoras theorem

I was with you up until this. What, man? Really? It seems that every time I enter any field of engineering or design whatsoever I have to use that theorem at some point. Even many of my past hobbies have utilized it. Good carpenters use it constantly.

So? Photographers have to learn how to use Photoshop, because it's relevant to their industry. That doesn't mean everyone else should have to learn how to use it.

That's not a good analogy. Photoshop is a specific tool, specific to one industry. I think a better analogy would be something like the concept of negative space, or color theory.
