Character Quote by Werner Heisenberg
“Both matter and radiation possess a remarkable duality of character, as they sometimes exhibit the properties of waves, at other times those of particles. Now it is obvious that a thing cannot be a form of wave motion and composed of particles at the same time - the two concepts are too different”
About This Quote
Source Lecture: Quantum Mechanics Fundamentals, 1927
Wave‑particle duality shows that entities can display mutually exclusive properties depending on observation, highlighting limits of classical description.
In simple terms: Things can act like waves or particles, not both at once.

A Different Perspective
The statement oversimplifies nuanced quantum behavior.
![“It was about three o'clock at night when the final result of the calculation [which gave birth to quantum mechanics] lay before me ... At first I was deeply shaken ... I was so excited that I could not think of sleep. So I left the house ... and awaited the sunrise on top of a rock.” quote by Werner Heisenberg](https://sms4smile.com/quotes/img-quotes/bba/werner-heisenberg-4501_birth_it-was-about-three-o-clock-at-night-when_265746.jpg)
