Frequently Asked Questions

What is the mechanism behind the atomic clock's accuracy?

We can attribute the incredible accuracy of the atomic clock to the principles of quantum mechanics. At its core, the atomic clock relies on the behavior of atoms to keep time. Specifically, it utilizes a caesium fountain that allows us to measure very short amounts of time with incredible precision. The fountain works by cooling a cloud of caesium atoms and then launching them upward with lasers. As they fall back down, we measure their transition between energy levels to determine how much time has passed. This process is repeated over and over again, allowing us to track time with an accuracy of up to one second per 100 million years! It's truly remarkable what modern technology can achieve using the principles of physics and mathematics.
