The wave determines the probable location of the photon of light when it is detected. The wave character of light is not vibrating stuff like a wave of water but rather a wavelike function encoding information about where you'll find the photon of light once it is detected. Until it reaches the detector plate, like the electron, it is seemingly passing through both slits simultaneously, making its mind up about its location only once it is observed \[...\]. It's this act of observation that is such a strange feature of quantum physics. Until I ask the detector to pick up where the electron is, the particle should be thought of as probabilistically distributed over space, with a probability described by a mathematical function that has wavelike characteristics. The effect of the two slits on this mathematical wave function alters it in such a way that the electron is forbidden from being located at some points on the detector plate. But when the particle is observed, the die is cast, probabilities disappear, and the particle must decide on a location.”” [Marcus du Sautoy](https://sms4smile.com/quotes/author/marcus-du-sautoy/) ## About This Quote This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation. The quote explains that particles like photons and electrons behave as waves of probability until measured, at which point they assume a definite position. **In simple terms:** Particles are wave-like probabilities until observed, then become definite. Key Takeaway Recognize measurement collapses possibilities into reality. Themes physics quantum mechanics measurement probability wave-particle duality Mood curious thoughtful inquisitive Type educational explanatory philosophical When to use this quote - lab experiments - educational videos - science communication - philosophical discussions about reality Key Concepts probability wave collapse of wavefunction superposition observer effect Questions to Reflect On - How does observation influence reality? - What does “collapse” imply about determinism?
