The fundamental physical constant, often denoted as k and equal to 1.38 x 10-23 J/K, is called Boltzmann's constant. This constant plays an important role in statistical mechanics. In the late nineteenth century Austrian physicist Ludwig Eduard...

The Stefan–Boltzmann constant (also Stefan's constant), a physical constant denoted by the Greek letter σ, is the constant of proportionality in the Stefan–Boltzmann law: the total energy radiated per unit surface area of a black body in unit time...

Byline: RICH RADFORD NORFOLK -- BY RICH RADFORD THE VIRGINIAN-PILOT NORFOLK - Isaiah Hunter says he knows where his buddies sit at the Ted Constant Center and likes to acknowledge them with a wink and a nod. Alex Loughton...

If a constant of nature can vary, then so might laws of physics Sometimes it's the tiniest differences that change everything. This summer, astrophysicists reported tantalizing evidence of just such a discrepancy. Using one of the world's largest telescopes, a team...
