Awesome question at 34:50.

Is the answer it does but the object would have to be travelling very slowly in a frictionless environment (preferably without gravity pulling the wave down) to observe a wave. Rough calculations brings the velocity of a baseball down to 1E-24 m/s to even bring the wavelength into the nanometres region (1E-30 if you want to get your ruler on the case), and with such a low velocity (and therefore tiny force and tiny frequency) amplitude is going to be immeasurably small.

I think either the student or I is/are confused about the amplitude, as this is really I think he wants to observe, and observable amplitude can only exist with substantial force.

About de Broglie waves... I don't think whole baseball can be described as one particle, and therefore there is no zero momentum state either.

Indeed there is hope for our younger generations going by the methodology of MIT course worldwide.I wish the lecturers in MIT a better wisdom on their effort of research providing, students round the world a better opportunity to excel in science studies.
