ELI5: Explain Like I'm 5

Joachim Lambek

Okay kiddo, so let me explain to you about a man named Joachim Lambek. He was a super smart guy who loved math and language, and he found a way to combine them in a really cool way.

You know how when we talk, we use words to tell stories or ask questions? Well, Lambek figured out how to use math to understand how words and sentences work together in a sentence.

He used something called category theory, which is all about studying relationships between different things. In Lambek's case, he used it to figure out how different words in a sentence relate to each other.

For example, let's say we have the sentence "The cat chased the mouse." Lambek would use category theory to figure out that "cat" and "mouse" are related because the cat is doing something to the mouse (chasing it). He would also figure out that "chased" is the action that's happening, and "the" just tells us which cat and mouse we're talking about.

Lambek's work has helped us understand how different languages work and how they're structured. It's really amazing how a love for math and language can come together to create something so cool!
