JACKSONVILLE, Fla. — One second. It's one of the most minute measurements of time, but one second can have a lifetime of impact on an athlete. One second can be the difference between standing atop ...

Physicists have built the most accurate clock ever: one that gains or loses only one second every 40 billion years 1. Alexander Aeppli at the research institute JILA in Boulder, Colorado, and his ...

Atomic clocks are already the world's most precise time keepers, but physicists are tinkering with a new design that could make them "50 times more precise than today's best designs," according to new ...
