In 1924 a French physicist and nobleman, Prince Louis de Broglie (pronounced
“de broy”;), made a remarkable proposal about the nature of matter. His
reasoning, freely paraphrased, went like this: Nature loves symmetry. Light is
dualistic in nature, behaving in some situations like waves and in others like par-
ticles. If nature is symmetric, this duality should also hold for matter. Electrons
and protons, which we usually think of as particles, may in some situations behave like waves.
