Frequently Asked Questions
What is Planck’s constant?
The Planck constant (ħ) is basically the “resolution” of the universe – the size of the pixels that create our world. This constant is a central physical constant in quantum mechanics, first recognized in 1900 by Max Planck. Planck discovered that physical action cannot take on an arbitrary value.
