Summary:

For centuries, time was measured by the apparent movement of the Sun, in other words by the rotation of the planet Earth around itself. A few decades ago, physicists redefined a second through the fundamental properties of atoms. How? Whatever for? This work presents the history of this unit of universal time, the second.
