Currently, Planck's constant is expressed as 6.62607015 x 10^(-34) joule-seconds. You might want to remember that in case you ever need to save the world.

The new NIST measurement of Planck’s constant is 6.626069934 x 10 −34 kg∙m 2 /s, with an uncertainty of only 13 parts per billion. NIST’s previous measurement , published last year, had an ...

The excitation energy of particle ℓ is ħω ℓ, where ħ is the reduced Planck constant, and and are the angular frequency and wavevector of the incident single photon, respectively.

But scientists at the National Institute of Standards and Technology noticed during their viewing of “Stranger Things” that this is the value established for Planck’s constant in 2014.. In ...

On the plus side it’s pretty cool to estimate planck’s constant using an LED and a voltmeter. On the other hand, it’s frustrating because all the estimates are 10-20% low.

Planck hypothesized the existence of a constant, now known as Planck’s constant, or h , which links a wave or particle’s frequency with its total energy. Today, we know that h = 6.6262 x 10 ...

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 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 ...
