Topic: electrons

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...…

Discovery of the electron

In the article on elementary particles, we read that, in 1804, John Dalton demonstrated the existence of atoms, which he imagined as hard spheres. More than 90 years later, in 1897, the experiments of Joseph John Thomson, a British physicist, showed that atoms contain electrons, tiny particles...…

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...…

Why do Millie meet electrons first?

Electrons were discovered before other elementary particles. Joseph John Thomson demonstrated their existence in 1897, and for this, he was awarded the Nobel Prize in Physics in 1906. To learn more, read the story of the discovery of the electron.

Do electrons spin?

Electron spin makes us picture electrons as if they "spin" like a tiny toy top spinning on a table. But here’s the thing: electrons don’t spin like that at all! In the article Electron's spin - Part 1, we discovered that scientists once thought electrons might be spinning, so they gave this spe...…
