The wavelength of an elephantWhat is the wavelength of a trotting elephant? One may doubt whether the equation should be applied to an elephant, which is not just a single particle but a rather large collection of them. Throwing caution to the wind, however, we estimate the elephant's mass at 103 kg and its trotting speed at 10 m/s. Its wavelength is therefore roughly
