Episode notes

In the context of my thesis, the things that i'm really a having in the back of my mind are words or expressions in a language. So when i take red and fire truck and concatenate them, i get a phrase rather than a single word. And then maybe you might want to say, you know, how? How does the algebraic structure pare well with the fact that i have different lengths involved? Um, but there are actually tools in algebra that deal with that.

Mathematics is often thought of as the pinnacle of crisp precision: the square of the hypotenuse of a right triangle isn’t “roughly” the sum of the squares of the other two sides, it’s exactly that. But we live in a world of messy imprecision, and increasingly we need sophisticated techniques to quantify and deal with approximate statistical relations rather than perfect ones. Modern mathematicians have noticed, and are taking up the challenge. Tai-Danae Bradley is a mathematician who employs very high-level ideas — category theory, topology, quantum probability theory — to analyze real-world phenomena like the structure of natural-language speech. We explore a number of cool ideas and what kinds of places they are leading us to.
