Constants are supposed to be, well, constant. In physics there are a number of fundamental constants, such as the speed of light, Planck's constant, and the charge of an electron that are essential to ...

Essential for life: this illustration shows how fundamental constants of nature set the fundamental lower limit for liquid viscosity. (Courtesy: thehackneycollective.com) The values of the fundamental ...

Detecting or constraining the possible time variations of fundamental physical constants is an important step toward a complete understanding of basic physics and hence the world in which we live. A ...

The validation and application of theories in physics require the measurement of universal values known as fundamental constants. A team of French researchers* has just conducted the most accurate ...

The redefinition of several physical base units planned for 2018 requires precise knowledge of the values of certain fundamental physical constants. Scientists are working hard to meet the deadlines ...

It turns out that the definitions of nature's fundamental constants are anything but. In fact, new scientific research shows that we've been underestimating electromagnetic force and overestimating ...

One of the most exciting prospects in physics has been discovering that fundamental constants are not actually constant at all. When I first started writing, physicists and astronomers were just ...
