Using an atom interferometer, scientists have tested one of the foundations of Einstein's general theory of relativity: that time slows down in a gravitational field. Their experiment proves that ...

INTERFEROMETERS for the testing and corretion of prisms and of lenses (for axial pencils) have been described in the Philosophical Magazine (vol. xxxv., January, 1918, p. 49). In its simplest form the ...

Nanopositioning specialist Queensgate and the UK’s National Physical Laboratory (NPL) have forged a productive collaboration yielding a good-practice implementation model for Queensgate’s in-house ...

A team of researchers from the University of Glasgow and the University of Southampton has devised a novel way to test quantum mechanics in a non-inertial reference frame by using a rotating ...

A lot of what I write is about measurement, not because I’m in love with calipers, but because the cutting edge of physics is at the limit of what we can measure. That means that when you want to ...

Arvix paper contends the spacetime distortions resulting from the experimentally obtainable electric field of a parallel plate capacitor configuration cannot be detected by the White-Juday Warp Field ...

(Phys.org)—The laws of physics are the same no matter which direction you're facing or how fast you're moving—it's such an intuitive concept that most people probably don't know that it has a name: ...

The Einstein equivalence principle (EEP) has a central role in the understanding of gravity and space–time. In its weak form, or weak equivalence principle (WEP), it directly implies equivalence ...

Space Warp equations are being tested using an instrument called the White-Juday Warp Field Interferometer. At Johnson Space Center, Eagleworks has initiated an interferometer test bed that will try ...

Warming up: illustration of the interferometer. (Courtesy: APS / Alan Stonebreaker) An atom interferometer that does not have to be cooled to cryognenic temperatures has been created by physicists in ...

The concept of measuring surface roughness originated nearly a century ago as a means to prevent uncertainty and disputes between manufacturers and buyers. Now, it has become a common identifier used ...
