This set-up is very similar to the one that Henry Cavendish employed in 1797 to measure the strength of the gravitational force, but its purpose is different. The idea, the team say, would be to ...

Does gravity require extra dimensions? PBS.org has a new look and feel! ... It’s the Cavendish experiment, performed by Brit Henry Cavendish in the late 18th century.

In 1798, Henry Cavendish looked through his telescope into a darkened room. Inside the room, large lead spheres hung next to small two-inch counterparts, gravity bringing them slowly together. From ...

The crowning achievement of the 18th-century researcher was the design of the first experiment to measure the force of gravity between masses in a lab. ... Henry Cavendish was an odd man.

In 1798, Henry Cavendish set the standard for laboratory experiments to measure the gravitational constant using a technique called the torsion balance. That technique relies on a sort of modified ...

I n 1797 Henry Cavendish, ... who has been recounting the Cavendish experiment during a Skype call. “It was the first precision tabletop experiment [with gravity].” Cavendish’s 220-year-old ...

The same gravitational law, and constant, describes gravity's effects on all scales, from Earth to the cosmos. ... only came about with Henry Cavendish's experiments in the late 18th century.

Yet despite hundreds of elegant experiments since British physicist Henry Cavendish first measured it 225 years ago, G remains among the least precisely known of the fundamental constants.
