> Things like Math and engineering are all rigid and rules based

Depends where in math, in things like particle physics things get all wibbly wobbly is my cat dead or alive. In things like engineering quite often what you're dealing with is probability based, but you just stack the deck so far in your favor the probability is 1.

As they say, building a bridge that doesn't fall down is easy. Building a bridge that barely doesn't fall down is much harder.
