That equation is E = hv, where E is energy, h is Planck’s constant, and v is frequency. This is where our team of Lego brick-wielding researchers comes in. Working at the National Institute of ...

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-Einstein ...

Planck's constant is one of the fundamental constants that sets up all the "rules" for how things work in our universe. (It’s named after the theoretical physicist Max Planck, who is best known for ...
