À propos de cet audio
Time feels natural, but the way we measure it is entirely human-made. From Mesopotamian star charts and Egyptian solar calendars to Roman reforms, medieval clock towers, and modern atomic precision, this episode explores how we constructed the framework of time itself.
3 Timeless Takeaways:
- How ancient Mesopotamia and Egypt laid the foundations for calendars and timekeeping.
- Why the Babylonians chose base-60 and how it still shapes our clocks today.
- How mechanical clocks, trains, and atomic physics transformed time into the precise system we live by.
