Ok, as I understand it we have no way to determine the speed which we are moving at in an absolute sense.<BR><BR>We can say "We are moving 20 miles per hour in the car relative to the road" or "The ...

Cold atoms could also potentially measure much lower vacuum pressures than ion gauges can. The current lowest pressure they’ve reliably measured is around 10 -9 Pa, and NIST scientists are working on ...

By using something called a quantum grid, scientists have found a clever way to simultaneously measure momentum and position ...

For centuries, scientific progress has depended on more precise tools for measuring the world around us. Galileo’s telescope ...

Most of us intuitively feel that reality ought to exist just fine on its own when we aren’t looking. If a tree falls in a forest when no one is around to hear the crash, the air still vibrates with ...

For almost a century, Heisenberg's uncertainty principle has stood as one of the defining ideas of quantum physics: a ...

A team led by physicists at Washington University in St. Louis has created quantum sensors that can survive in extreme ...

The Royal Swedish Academy of Science has awarded the 2023 Nobel Prize in Physics to Pierre Agostini, Ferenc Krausz and Anne L'Huillier for work that's "given humanity new tools for exploring the world ...
