SUMMARY

The discussion centers on the conceptual understanding of a proton's position in quantum mechanics (QM) and the implications of measurement. Participants emphasize the importance of clearly defining questions in physics, particularly in QM, where the nature of measurement and observation is critical. The conversation highlights the need for specificity when discussing quantum phenomena, as vague terms like "imagine" and "appear" can lead to confusion. The exchange encourages a more structured approach to formulating scientific inquiries.

PREREQUISITES
  • Basic understanding of quantum mechanics principles
  • Familiarity with measurement theory in physics
  • Knowledge of particle behavior and wave-particle duality
  • Experience with scientific literature and research methodologies
NEXT STEPS
  • Study quantum mechanics measurement theory
  • Explore the concept of wave-particle duality in depth
  • Learn about the role of observation in quantum systems
  • Investigate how to formulate scientific questions effectively
USEFUL FOR

Students of physics, amateur physicists, and anyone interested in deepening their understanding of quantum mechanics and the philosophy of science.

When you imagine a proton in a certain place during an experiment and expect it to be
everywhere else where does the proton appear?

Back up a bit. Your question makes very little sense.

What do you mean by "imagine"? Who's imagining what? Rather than "imagine" something, why don't you describe a particular situation where this proton is in?

Secondly, what do you mean by "appear"? Is a particular measurement being made onto the system? Things just don't "appear", and certainly it is not something you can tell without some sort of a detection/measurement.

You posted this in the Quantum Physics forum, which probably means you're trying to understand a particular aspect of QM. It would be nice if you are a bit more verbose in describing what it is that you're trying to understand. In physics, and especially in QM, the "questions" that we ask of Nature is as important as the answers we're trying to get from her. So these questions have to be clearly defined.

As my name suggest I am an amateur. I have developed a great interest in Physics, The Universe and workings of the Universe and I am looking for possibilities to go to university, but when one is not rich or 20 anymore it is difficult and you look for ways to learn and study anyway :smile:. At the moment I am just reading scientific literature and I see that I have to reformulate my question.

Thanks Zz for your constructive comment,

Regards,
Martyn
