Problem

A 5 g5\,\text{g} marble rolls across a table at 0.20 m s−10.20\,\text{m}\,\text{s}^{-1}, while an electron travels through the same laboratory at the same speed. Describe why the marble behaves classically whereas the electron can display quantum behavior, making specific reference to the relative sizes of their de Broglie wavelengths and any relevant length scales in the laboratory.
