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 ...

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 ...

Upper limit: a US Navy F/A-18 travelling near the speed of sound in air. The white halo comprises water droplets that have condensed from the air because of the sudden drop in pressure behind the ...

For nearly half a century, theoretical physicists have made a series of discoveries that certain constants in fundamental physics seem extraordinarily fine-tuned to allow for the emergence of a ...

One of the most dissatisfying aspects of modern physics is the fundamental constants. It’s not that they are constant that bothers anyone, it is their very existence that is offensive to ...

Controversy over whether the fundamental constants of nature change with time has reignited. A new study is casting doubt on an earlier claim that a key constant varied as the Universe evolved. The ...

The fundamental constants that govern the laws of nature are being determined with increasing accuracy. A new paper outlines the proceedings from this year's Workshop on the Determination of the ...

Forbes contributors publish independent expert analyses and insights. I write about physics, science, academia, and pop culture. One promising avenue for this sort of study is a search for changes in ...

This is a short introductory note to the texts of lectures presented at a Royal Society Discussion meeting held on 14-15 Febrary 2005 and now published in this issue of Philosophical Transactions A.
