Second
Lire ce billet en français →The unit of time can be difficult to understand for children. Why does an hour sleeping, an hour in a car and an hour playing seem to have completely different durations? Because our perception of time differs. There are too many factors to know what’s happening in the marvel of complexity that is our brain.
But when we talk about time to children, a question comes up. A question that almost no adult asks, because “that’s just how it is”: why does a second last a second? Why this unit of time? Why 24 hours, 60 minutes, 60 seconds… Obviously, no one was there to know, but according to Colton, the second comes from the only thing our ancestors had access to: themselves. Indeed, the average heartbeat rate is about 60 beats per minute, or… one per second. Each hour is therefore made up of 3600 heartbeats of our ancestors.
