It is just the cool factor. [Stoppi] shows us several neat ways to measure Planck’s constant (German language, Google Translate link) using things like LEDs, solar cells, and common test equipment.

Planck’s constant helps us understand atomic-sized things. One of the best ways to grok it is through this experiment involving different colors of light.

Let’s talk about Planck keyboards, a special keyboard that’s designed to be more ergonomic depending on who you are. Switch ...

The NIST-4 Kibble balance. The instrument was used to calculate Planck’s constant, an important step toward redefining the kilogram. (Jennifer Lauren Lee/NIST PML) ...

Planck’s constant has the dimensions of energy multiplied by time and Flambaum says there is no point in looking for variations in fundamental constants that have dimensions because the units defining ...

Measuring Planck's constant, NIST's watt balance brings world closer to new kilogram Date: June 21, 2016 Source: National Institute of Standards and Technology (NIST) Summary: A high-tech version ...

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

A kilogram will now be based on the Planck constant, a constant observed in the natural world, rather than Le Grand K, a piece of metal kept under lock and key in Paris since 1889.

Using a state-of-the-art device for measuring mass, researchers have made their most precise determination yet of Planck's constant, an important value in science that will help to redefine the ...

With enough accurate measurements of Planck's constant, scientists will eventually fix its value to a very high degree of precision, allowing highly accurate measurements of the kilogram.
