How to rebuild an atomic clock
Atomic clocks are crucial for everyday living as they help our telecommunications, electrical power grids, GPS systems, transportation, and other processes around the world keep precise time. Some of these clocks use lasers and special resonator cavi.....»»
Near-threshold resonance helps explain a controversial measurement of exotic decay in beryllium-11
Most mass in everyday matter around us resides in protons and neutrons inside the atomic nucleus. However, the lifetime of a free neutron—one not bounded to a nucleus—is unstable, decaying by a process called beta decay. For neutrons, beta decay.....»»
Intel launches 13th Gen Core processor family
