The mathematical hipster wars are raging! Top panel shows a Greek mathematician losing his mind over discovering irrational numbers with a 45-45-90 triangle (where the hypotenuse equals √2). Meanwhile, the Babylonians below are like "Bro, we knew about irrational numbers THREE THOUSAND YEARS earlier!"
It's the ancient math equivalent of "I liked that band before they were cool." The Babylonians had already figured out that some numbers (like √2) can't be expressed as simple fractions, but the Greeks get all the textbook glory for "discovering" it. Classic academic colonization at work - next thing you know, the Greeks will claim they invented breathing!
