Planck’s constant is one of the most important numbers in science. It describes the relationship between the energy and frequency of an electromagnetic wave in an equation known as the Planck-Einstein ...

The remarkable thing about our universe is that it’s possible to explore at least some of its inner workings with very simple tools. Gravity is one example, to which [Galileo]’s inclined planes and ...

We aren’t sure if [Looking Glass Universe] didn’t trust the accepted number for Planck’s constant, or just wanted the experience of measuring it herself. Either way, she took ...

Researchers at the National Institute of Standards and Technology (NIST) have made their most precise determination yet of Planck’s constant. This will let NIST redefine the kilogram, the official ...

A high-tech version of a balance scale has just brought scientists a critical step closer toward a new and improved definition of the kilogram. The scale, called the NIST-4 watt balance, has conducted ...

Planck's constant is a pretty important part of modern physics, but it's also pretty confusing. Maybe you were wondering what it was while reading about the new kilogram definition. Well never fear, ...

Planck's Length is the length below which the concept of length loses its meaning. Huh? Planck's Length is the length below which the concept of length loses its meaning. What exactly does that mean ...

Editor's note: This article contains spoilers for the Netflix original series "Stranger Things." Season 3 of the Netflix hit series "Stranger Things" continues to prove the show's appreciation for ...

Researchers from the CNRS and Université de Sherbrooke, have discovered a universal law for the electronic properties of high-temperature superconductors. They exposed superconductors to an intense ...

The perfect sphere that will be used to redefine the kilogram in terms of the Planck constant in 2018 has been shown to consist of the purest silicon ever made. The kilogram is the only unit still ...

A high-tech version of an old-fashioned balance scale at the National Institute of Standards and Technology (NIST) has just brought scientists a critical step closer toward a new and improved ...
