In 2024, TU Wien presented the world's first nuclear clock. Now it has been demonstrated that the technology can also be used to investigate unresolved questions in fundamental physics. Thorium atomic ...

Scientists in Germany have unveiled that the world’s most precise mobile atomic clock is so accurate that it will be off by only one second after 15 billion years of continuous operation. Optical ...

(CNN) — No, I did not prepare for the end of Daylight Saving Time this past weekend, when most US states set clocks back an hour. Sunrise and sunset now come an hour earlier, despite my protestations.
