I'm Samir Patel, editor-in-chief at Quanta Magazine. Our mission at Quanta is to cover what we call basic or fundamental research in science and math. That means the kind of work that's driven by curiosity and discovery and the search for knowledge. We're interested in how and why everything around us works the way that it does.

the biggest ideas and the tiniest details. Join me for the Quanta podcast, your weekly dispatch

from the frontiers of science and math.
