What do you mean? Observing particle A is another way of saying measuring state of particle B after interaction with A, specifically comparing state B1 to state B0 expected when no interaction has occurred.
Using words "not really" is like saying I should've used exact particle names and state matrices instead of placeholders.
- scotty79 8y agoMath is solid. My objection is to calling it "observing a particle". It's like watching animated movie and saying "I observe moving Donald Duck". There's no Donald Duck. What you see is 24 completely separate slightly differnt pictures per second of something that give you an illustion that Donald Duck exists and he is moving. It's perfectly fine to say Donald Duck is moving when you are considering Earth orbiting the Sun, but when you are talking about particles and quantum it misleads you into thinking Schrodinger's cat should be dead and alive before you open the box. Conversly, thinking about "paricles" not as specks of dust but as whole fuzzy clouds may give you a lot of new intuitive understanding of what's actually happening. Like when you drop planetary model of atom and you consider orbitals. Then you can understand chemical bonds better. Things that didn't make sense earlier, like benzene make now perfect sense, orbital hybridisation brings new explanations.
