Quantum physics explanation problem

Click For Summary
SUMMARY

The discussion centers on the interpretation of quantum physics, specifically regarding the behavior of particles like photons and electrons in relation to their probability wave functions. One participant argues that until a particle interacts with something, it exists in a state of probability across multiple locations, while another believes it occupies a definite position. The conversation references the double-slit experiment as a key example of how wave functions can interfere, highlighting the ongoing debate about the physical interpretation of quantum mechanics. Ultimately, the mathematics of quantum theory is effective, but its physical implications remain uncertain.

PREREQUISITES
  • Understanding of quantum mechanics principles
  • Familiarity with the double-slit experiment
  • Knowledge of probability wave functions
  • Basic grasp of quantum interpretations (e.g., Copenhagen interpretation)
NEXT STEPS
  • Research the Copenhagen interpretation of quantum mechanics
  • Explore the implications of the double-slit experiment on particle behavior
  • Study the concept of wave-particle duality in quantum physics
  • Investigate alternative interpretations of quantum mechanics, such as Many-Worlds or pilot-wave theory
USEFUL FOR

Students of physics, educators explaining quantum concepts, and anyone interested in the philosophical implications of quantum mechanics.

i have a friend and i am trying to explain to him that until it interacts with something it is evrywhere and no where but has more of a probability in being in place a than place b or c but until it interacts we don't know so there for it is evrywhere. that is the concept as i understand it. he says it is in one spot but has probability of being evrywhere who is right and if me how do i convince him?

What is "it" referring to?

We don't have an answer yet Hawkdron496.

For example there is an (quantum) interpretation that posits:

The photon/particle/electron passes through one slit (in a single particle double slit experiment) and its (probability) wave function "passes" through both. And then the wave-functions interfere.

This would slightly favor our friend's idea. Or you could find an interpretation that tends to favor your idea.

Or you could ask him to treat you to ice cream or pizza or whatever... if you were to provide him with an interpretation that favors his idea...;)

What we know is that some of our equations and mathematics (the concept of probability wave-function and its propagation) works very well.

We don't know yet how to interpret the mathematics "physically/in-reality"
