<P> Through the work of Max Planck , Albert Einstein , Louis de Broglie , Arthur Compton , Niels Bohr and many others , current scientific theory holds that all particles also have a wave nature ( and vice versa ) . This phenomenon has been verified not only for elementary particles , but also for compound particles like atoms and even molecules . For macroscopic particles , because of their extremely short wavelengths , wave properties usually can not be detected . </P>
