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 ...

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 ...

Scientists reveal unprecedented ability to "side-step" the Heisenberg Uncertainty Principle by simultaneously measuring ...

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

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

This research suggests that even chaotic, unpredictable phenomena, like waves on a shore or the beating of a heart, can be used to measure the passage of time. This new idea goes against the ...

WashU physicists build quantum sensors in boron nitride sheets to study magnetism and stress under extreme pressure.

The flow of time isn’t as consistent as we might think – gravity slows it down, so clocks on the surface of Earth tick slower than those in space. Now researchers have measured time passing at ...
