Fog Memes

The peak of mathematical humor right here! The top image shows a foggy road and the mathematical notation f(g(x)) - literally "fog of x" or function g inside function f. When asked to spot the difference, the response is spot on - they ARE the same picture! It's a brilliant composition equation where fog = f(g(x)). This is the kind of nerdy wordplay that makes mathematicians snort coffee through their noses during calculus lectures. Once you see it, you can never unsee it. Function composition has never been this hilarious!
