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...…

Double-slit experiment
The double-slit experiment was invented in 1801 by Thomas Young to study the nature of light. Young was convinced that light behaved like a wave, while other scientists, such as Isaac Newton, preferred to think of it as composed of corpuscles (= light particles).
Young decided to pass a beam o...…

Schroedinger's cat
Schrödinger's cat is the most well-known thought experiment in quantum physics. A thought experiment is like an imagination game! It’s when you use your imagination to think about a situation, even if you can’t actually do it in real life. Schrödinger used it to illustrate the strange world of qua...…

Discovery of electron spin
In 1922, Otto Stern and Walther Gerlach, two German physicists, conducted a groundbreaking experiment that demonstrated that electron spin and magnetism were related. To understand it, let’s imagine you have a strong magnet and a bunch of tiny beads. If you throw the non-magnetic beads through the m...…
