Description

Math is everywhere—from counting change to launching rockets—but what is it really? In this episode of Explain It Like I’m 5, Alex explores one of humanity’s biggest brain-bending mysteries: what math actually is, where it came from, and why it seems to rule everything around us.


You’ll learn how math evolved from tally marks and goat-counting to calculus and algorithms, why it predicts the universe so perfectly, and whether numbers were invented or discovered. Along the way, we’ll uncover fascinating math facts, from zero’s scandalous history to Fibonacci spirals in pinecones, and why cicadas use prime numbers to stay alive.


By the end, you’ll see math not as a school subject, but as the language the universe uses to talk to itself.
