We revisit an interview with Eugenia Cheng, the author of How to Bake Pi, who translates higher math using metaphors that even the most mathematically disinclined can comprehend: infinite layers of puff pastry, endless jars of marmalade, and deep-dish pi(e). She talks about the false dichotomy between mathematics and art, and how understanding math helps you see the world in a new light. Also, how five-year-olds sometimes pose the most difficult questions for mathematicians to answer, like: what’s a number?

Go beyond the episode:

• Eugenia Cheng’s Beyond Infinity
• And her attempt to teach Stephen Colbert how to make puff pastry
• Natalie Angier’s review of How to Bake Pi (verdict: delicious!)
• Watch an animated explanation of the Infinite Hotel Paradox from TED-Ed
