I’m pretty darned nerdy. I’ve watched my share, your share, and all of your neighbors’ share of the Science Channel, National Geographic, the History Channel, Nova, Discovery Channel, and every other sciency-nerdy thing I could get my eyes on. But I’ve never heard of the battery that’s been running for 176 years. Come on, that’s cool! It’s been ringing a bell all that time. Billions of time. We have only a loose idea of how it’s built, and we can’t figure it out without destroying it. Anyway, Sally Page tells us all about it in this marvelous video. Also, 😍.
