Quantum timekeeping is supposed to be the ultimate in efficiency, with tiny devices that tick using the rules of quantum mechanics instead of swinging pendulums or vibrating quartz. Yet new work on a ...
What if the most difficult part of keeping time wasn’t running the clock, but rather simply reading it? That counterintuitive reality has now been demonstrated on the smallest scales of quantum ...
Scientists built a tiny clock from single-electron jumps to probe the true energy cost of quantum timekeeping. They discovered that reading the clock’s output requires vastly more energy than the ...

With phones banned, some students realise they don’t remember how to read analog clocks in school
Some New York City schools banned phones to improve focus, but the move revealed a new issue. Many students have forgotten how to read analog clocks, leading teachers to revisit the basics of clock ...
The steady tick of a clock usually feels simple and dependable. Something swings or vibrates in a controlled rhythm and marks the passing of each moment. What you rarely notice is the hidden cost ...
