Researchers have succeeded in measuring the gravitational field of a gold sphere, just 2 mm in diameter, using a highly sensitive pendulum - and thus the smallest gravitational force. The experiment ...

Charles Sanders Peirce, a practicing scientist and proponent of philosophical pragmatism, began the gravity program of the U.S. Coast and Geodetic Survey in the early 1870s, at a time when his father ...

Despite more than 200 years of experiments, the best laboratory determinations of the force of gravity have yielded no better than a ballpark figure. Adding to the haziness, metrologists have scarcely ...

The smallest gravitational force ever recorded has been measured, with scientists upturning common assumptions about just what counts as "too small" to be quantified. Although all objects demonstrate ...

IIIF provides researchers rich metadata and media viewing options for comparison of works across cultural heritage collections. Visit the IIIF page to learn more. Thomas C. Mendenhall, who became ...

Gravity may feel like one of the most familiar forces, but it’s actually among those we understand least. We know our current model of gravity is inconsistent with quantum mechanics. It also fails to ...

The research provides new insight into the maneuvers required to safely and quickly transport heavy loads. In the beginning, all that Stephan Schlamminger wanted to do was to write down an equation ...
