A better option is to develop a new definition based on a mathematical foundation that can be calculated anywhere, and the Planck constant fits the bill. This formula allows researchers to find ...

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 ...

Planck's constant is one of the fundamental constants ... There is another version of this energy equation. Since the disturbance is from light, we could describe it with a wavelength instead ...

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.

That’s pretty much all you need for instruments to determine Planck’s constant to a decent degree of precision, the way that [poblocki1982]’s did. There’s a little more to it, of course ...

While universal formulas exist for every other phase transition (liquid-to-gas, gas-to-liquid, even solid-to-gas), no such formula exists ... that leverages Planck’s constant and electron ...

metrologists want to redefine the kilogram in terms of Planck’s constant. Lying at the heart of quantum mechanics, h links the frequency of a photon to its energy, which in turn can be related to mass ...

In 1878—before Einstein was born, before quantum mechanics, before we knew that our galaxy was one among many—a well-known physicist named Phillip von Jolly told young Max Planck, a student ...
