Dustin : do you know planck's constant ? Suzie: do you know the earth orbits the sun? Dustin: So I know it starts with two sixes and then uh what is it...? Suzie: okay let me just be clear on this. I havent heard from you in a while and now you want a mathematical equation that you should know so you can... save the world? Dustin: Suzie-poo I promise I will make it up to you as soon as possible. Suzie: you could make it up to me now Dustin:what? Suzie: I want to hear it Dustin : not right now! Suzie: yes now Dusti-bun! Dustin: Suzie-poo this is urgent!! Suzie: yes yes youre saving the world I heard you the first time but dennis is also saving earth sea and he is about to confront the shadow so this is suzie signing off. Dustin: wait wait wait okay okay. ..okay Dustin: aaa shit... (starts singing never ending story) Suzie: Planck's constant is 6.62607004
a fundamental constant, equal to the energy of a quantum of electromagnetic radiation divided by its frequency, with a value of 6.626 × 10⁻³⁴ joule-seconds.
The Planck constant is denoted by a capital H (ℎ).
