Heisenberg's uncertainty principle
In the article on wave-particle duality, we explained that the world of particles is filled with strange phenomena that differ significantly from our everyday experiences. For instance, in our daily lives, it's normal to measure the speed of a car while simultaneously knowing its precise position...…

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....…

Empty space in atoms
In the article about the discovery of the electron, we read that the atom is more empty than full. The nucleus is ten thousand times smaller than the atom, and the electrons are very far apart. This is why, when Millie first arrives in the world of particles (book number 1), she feels complete...…

Spin
In Book 1, Millie is intrigued by the electrons’ pointy "hats" and curiously asks about them. She soon discovers that these aren’t hats at all, but a built-in feature of electrons known as spin.
Spin is an intrinsic property of electrons and all quantum particles. An intrinsic property is a ch...…
