Constant of Planck
Constant of Max Planck seems to be the smallest unit of measure of the universe.
Its value is 6.626068 × 10*exp(-34) m² kg / s (ou J/s)
Equation of Planck: E=hf=hc/lambda, where E=energy, f=frequency, h=constant of Planck, c=speed of the light, lambda=langth of the radio wave
Research of Planck allowed Einstein to elaborate his theory of the relativity five years later.
