So electrons are not tiny particles at all: they are ripples in a field that fills the universe. Here is how Louis de Broglie put it memorably in 1924: The energy of an electron is spread over all space with a strong concentration in a very small region… . That which makes an electron an atom of energy is not its small volume that it occupies in space, I repeat it occupies all space, but the fact that it is undividable, that it constitutes a unit.
