How particles defy classical physics to cross impossible barriers

Quantum Tunneling Explained in Simple Words for Beginners · 3:25 · Video: Science ABC · Watch at the source

In short: Explore the strange mechanics of quantum tunneling. This animated explainer breaks down how particles bypass physical obstacles, a phenomenon essential to both the life of stars and modern microscopy.

The video explores the mechanics of quantum tunneling, focusing on wave-particle duality and the nature of probability waves. It explains why an electron's location remains uncertain and how this allows particles to penetrate barriers that classical physics deems impassable.

Beyond the theory, the presentation highlights the profound real-world implications of this phenomenon. It details how quantum tunneling powers nuclear fusion within the Sun and enables the Scanning Tunneling Microscope (STM) to image individual atoms directly.
