AI overview

A second is a unit of time that results from dividing a day into progressively smaller units—first into 24 hours, then into 60 minutes, and finally into 60 seconds each, giving 86,400 seconds per day. This measurement system, originally based on Earth's rotation, remains the foundation of the Universal Time 1 (UT1) timekeeping system used today.

Het woord seconde is afkomstig van het Latijnse pars minuta secunda dat letterlijk tweede kleine deel betekent. Voor een deel heeft dat betrekking op het zestigtallige stelsel zoals dat in Babylon in gebruik was. Men verdeelt tegenwoordig nog steeds uren en booggraden eerst in 60 minuten (dat wil zeggen kleine deeltjes) en deze weer in 60 seconden (tweede kleine deeltjes).Het woord heeft betekenissen in de natuurkunde, de wiskunde en de muziek.
