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 ...

That h value is now called Planck's constant, and scientists can multiply it by the frequency of a wave to determine its overall energy. Recognizing that relationship led to the rise of quantum ...

Planck's discovery would ignite a flurry of research in a new field of physics called quantum mechanics. That h constant that Planck discovered would eventually be called Planck's constant ...

now known simply as Planck’s constant. Usually represented by the letter h, it’s the ratio of a photon's energy to its frequency, with units of kilograms multiplied square meters per second.

It’s represented by the letter h. The Planck constant has a value of 6.626 x 10-34 joule-seconds, and it mostly appears in calculations dealing with quantum mechanics. It turns out that really ...

The amount of energy is proportional to a very small quantity called h, known as Planck's constant, which subsequently shows up in almost all equations in quantum mechanics. The value of h ...

called Planck’s constant or h, is really as it says. The fact that it is, as far as we can tell – there does not seem much point in manufacturing suspense here – means that this is not ...

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.

v is frequency and h is Planck’s constant). This constant is set to become even more important because physicists are about to change the definition of mass so that it depends on Planck’s ...

The latest version of the watt balance at the US National Institute of Standards and Technology (NIST) has made its first measurement of Planck’s constant (h) with an uncertainty of 34 parts per ...

The amount of energy is proportional to a very small quantity called h, known as Planck's constant, which subsequently shows up in almost all equations in quantum mechanics. The value of h ...
