Why No One Has Been Able To Explain This Strange Formula In Forty-Five Years

Hey guys! We’re now live on Spotify🎧 Listen here: https://open.spotify.com/show/1Nm0Qc8tzIVXF6vXysxUzE?si=Brgn4LdFS3OaezqBPeFKiQ Three particles share everything except their weight: the electron inside every atom of your body, and two heavier copies that vanish almost as soon as they appear. Their weights look random. Yet a single line of arithmetic, written in 1981, turns them into a simple fraction, to a few parts in a million. So why has no one been able to say where it comes from? Tonight we follow that fraction slowly, through the laboratories that weighed these particles and the beautiful numbers that fooled physics before. Get comfortable and let this long walk through the strangest formula in particle physics keep you company tonight. Subscribe to Nap Theory if you like your mysteries taken the slow way.
