Book 1

In Book 1 in which Millie meets two electrons and her adventures begin, children get to know Millie and learn in a simple and playful way about electrons: the intrinsic nature of their spin, and their wave-particle duality. Children love this book. Here are some of their comments: I like Mil...…

Book 2

Book 2 in which a scarecrow gives Millie a brilliant idea about magnets is a humorous introduction to magnetism based on the orientation of electron spins. In this adventure, Millie wants to know what it is like to be an electron; she learns about magnetic fields, attractive and repulsive forces, a...…

Book 10

Millie micro nano pico Book 10 in which Millie fights for the liberation of infrared photons. At the beginning of this adventure, Millie asks the electrons to explain the nature of a rainbow. This allows her to learn that photons have a double nature: they are both particles and waves, just like el...…

Discovery of the electron as a wave

The first physicist to suggest that electrons could also exhibit wave-like behavior was the French nobleman Louis De Broglie. In 1924, De Broglie proposed the principle of wave-particle duality for all components of matter, not just electrons. This principle means that the particles that constitut...…

Wave or particle?

Thomas Young, a British scientist, was one of the first to explore this question. He invented the double-slit experiment to determine whether light behaves as a wave or as a collection of particles. The basic idea is to study a beam of objects whose nature is unknown and observe how they behave. T...…

Wave-particle duality

In the realm of particles, many phenomena are profoundly different from anything we experience in our everyday world. For instance, it seems obvious to us that a tennis ball and an ocean wave are two entirely different things. We’re also absolutely sure that ocean waves will never turn into tennis b...…

Wave function

In the article on the Heisenberg's uncertainty principle we discussed the section of Book 1 Millie wonders about the location of the electron that transformed into a wave. The answer she receives is: "Probably not far, but it could be anywhere." The word probably was not chosen by chance....…
