The uncertainty principle tells us that the more you know about where a quantum particle is, the less you can know about how fast it’s moving, and vice versa. In 2023, graduate student Alex Cohen stunned the math world when he posted a proof of the fractal uncertainty principle. The math, which combines chaos, quantum theory, and infinitely complex fractal structures, has been called a “foundational result.”On this episode of The Quanta Podcast, host Samir Patel speaks with writer Shalma Wegsman on this incredible breakthrough and how this principle has revealed a new deep way that quantum particles differ from classical ones.This topic was covered in a recent story for Quanta Magazine.  Each week on The Quanta Podcast, Quanta Magazine editor-in-chief Samir Patel and Senior Editor Hannah Waters speak with the people behind the award-winning publication to navigate through some of the most important and mind-expanding questions in science and math.
