If I understand her correctly, she proposes that the reason waves behave like particles is because they transfer energy essentially every zero-crossing : for example a photon is just one half of a wavelength of light.
She has a much more interesting explanation of what i am very poorly tryingto spit out here on youtube. Bear with, because honestly she is a whackadoo but she is a smart whackadoo.
Lemme know if you want a link to the video
