The universe behaves as both a particle and a wave

Particles and waves: The central mystery of quantum mechanics - Chad Orzel · 4:52 · Video: TED-Ed · Watch at the source

In short: How did we discover that the fundamental building blocks of reality defy our everyday logic? This video traces the historical progression of scientific discoveries that led to the core mystery of quantum mechanics.

The video explores the foundational principle that everything in the universe—including light, electrons, and atoms—exhibits both particle and wave characteristics simultaneously. Rather than presenting this as a sudden revelation, Chad Orzel recounts the specific lineage of scientists who contributed to our understanding of this phenomenon.

By examining the cumulative work of these researchers, the lesson illustrates how complex scientific truths are built through successive discoveries. It provides essential context for why this 'central mystery' remains one of the most profound and mind-boggling facts in modern physics.
