Jim Al-Khalili explains the experiment that reveals the "central mystery of quantum mechanics": the double slit experiment. Sometimes called the "two-slit" or "Young's" experiment, it demonstrates that matter and energy can display the characteristics of both waves and particles, establishing the principle known as wave-particle duality. Furthermore, it questions the role of the observer in the outcome of events and demonstrates the fundamental limitation of an observer to predict experimental r

The Sun shines because of quantum tunnelling ☀️ Jim Al-Khalili illustrates this phenomenon, where a particle passes through an energy barrier like it's "tunnelling" through a wall. Watch the full talk: youtube.com/watch?v=k-0pky806Fo | Royal Institution of Great Britain
