A trio of theoretical physicists at the Pennsylvania State University has calculated the upper limit for the possible quantization of time—they suggest 10−33 seconds as the upper limit for the period of a universal oscillator. ...
(Phys.org)—In 2011, scientists from the Institute Langevin in Paris built an array of 49 empty coke cans that resonate when exposed to an acoustic wave, causing the cans to produce sound similar to the way blowing across ...
Atomic clocks are the most precise timekeepers in the world. These exquisite instruments use lasers to measure the vibrations of atoms, which oscillate at a constant frequency, like many microscopic pendulums swinging in ...
