A tiny device that can make very precise measurements of the Earth’s gravity has been unveiled by physicists at the University of Glasgow in the UK. While their gravimeter is not quite as sensitive as ...

We continue our series the Adirondack Attic, with Andy Flynn. NCPR is collaborating with Andy and his sources at the Adirondack Museum and other... Dec 03, 2014 — We continue our series the Adirondack ...

Tools of this sort – called atom interferometers (AIs) – are now used to search for natural resources beneath the Earth’s surface, navigate deep underwater or in the air, and measure Newton’s ...

All objects have a mass and therefore a gravity field. Earth’s gravitational pull is slightly stronger in areas with more mass and slightly weaker in areas with less mass. Gravimeters measure ...

A gravimeter, as the name suggests, measures gravity. These specialized accelerometers can find underground resources and measure volcanic activity. Unfortunately, traditional instruments are ...

A novel quantum sensor that measures gravity changes by detecting variations in the travel time of falling atoms has been tested in a first of its kind experiment aboard an Australian navy ship. The ...

Physicists in California have loaded a bunch of ultracold caesium atoms into the back of a van and driven them up a hill to demonstrate how quantum interference can be used to measure gravity outside ...

Pictured is the European Space Agency's GRASS gravimeter. The first instrument to directly measure gravity on the surface of an asteroid has undergone testing in ESA’s Mechanical Systems Laboratory in ...
