Alphas Quote by Werner Heisenberg
“The incomplete knowledge of a system must be an essential part of every formulation in quantum theory. Quantum theoretical laws must be of a statistical kind. To give an example: we know that the radium atom emits alpha-radiation. Quantum theory can give us an indication of the probability that the alpha-particle will leave the nucleus in unit time, but it cannot predict at what precise point in time the emission will occur, for this is uncertain in principle.”

Explains that quantum theory provides statistical predictions, not precise events, emphasizing inherent uncertainty.
In simple terms: Quantum physics predicts probabilities, not exact moments.

A Different Perspective
The focus on uncertainty may discourage deterministic thinking.
![“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)
