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 ...

A fundamental constant that sets the size of the gravitational force between all objects has finally been pinned down using the quirky quantum behavior of tiny atoms. The new results could help set ...

The measurement of the Newtonian gravitational constant, G, remains one of the most challenging pursuits in experimental physics. A variety of techniques have been devised over the past two centuries, ...
