A Planck? Planck’s constant like the physics number for something complicated? Nah, that’s not keyboard related. But maybe it is. Let’s talk about Planck keyboards, a special keyboard that ...

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.

The Planck scale sets the universe’s minimum limit, beyond which the laws of physics break. In the late 1890s, physicist Max Planck proposed a set of units to simplify the expression of physics laws.

Higher orbits could have twice that value, or three times, or any other integer multiple of the Planck constant, but never any fraction of it (so not 1.3 or 2.6 and so forth).
