The Sun Isn't Overhead, Right?

Long before clocks, humans found creative ways to track time. From falling sand to burning incense, we tried it all. But it took a daydreaming astronomer and a whole lot of inventors to get us to the precise clocks we use today. Joy Dolo and co-host Kira set off on a tour of ancient timekeeping devices with reporter Carla Javier. Plus, we’ll learn about a clock buried deep in a mountain side that’s designed to keep ticking for 10,000 years. This episode is sponsored by StoryWorth (storyworth.com/forever).
