A scene from the movie Gravity. In real life, gravity is always bringing us down—particularly scientists who attempt to measure gravitational force. Try as they might, physicists cannot agree on a ...

Mutual attraction: why is it so difficult to pin down the gravitational constant? (Courtesy: iStock/FrankRamspott) Two extremely precise measurements of the gravitational constant G have yielded ...

In the quest to measure the fundamental constant that governs the strength of gravity, scientists are getting a wiggle on. Using a pair of meter-long, vibrating metal beams, scientists have made a new ...

The gravitational constant describes the intrinsic strength of gravity, and can be used to calculate the gravitational pull between two objects. The gravitational pull between two objects can be ...

Researchers have redetermined the gravitational constant G using a new measurement technique. Although there is still a large degree of uncertainty regarding this value, the new method offers great ...

Newton's law of universal gravitation, which describes the attractive force between two masses separated by the distance, is one of the greatest achievements in the 17th century. The strength of this ...

There are quite a few fundamental constants. These are things like the speed of light (c) the charge on an electron (e), and the Planck constant (h). These constants are determined with some type of ...

Caltech engineer Mory Gharib was poring over the digitized notebooks of Leonardo da Vinci one day, looking for sketches of flow visualization to share with his graduate students for inspiration.

A team of engineers studying the 500-year-old, backward writings of Leonardo da Vinci have found evidence that the Italian polymath was working out gravity a century before its foundations were ...

If you’re superstitious, a black cat in your path is bad luck, even if you keep your distance. Likewise, in quantum physics, particles can feel the influence of magnetic fields that they never come ...
