Solving the Measurement Problem: Imagine Yourself in a Room

Click For Summary

Discussion Overview

The discussion revolves around the measurement problem in quantum mechanics, using an analogy involving a person in a room without sensory perception. Participants explore the implications of measurement and the nature of knowledge regarding the state of particles, as well as the limitations of current understanding in experimental contexts.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant proposes an analogy where a person in a sensory-deprived room cannot know the location of another person without measurement, suggesting this reflects the measurement problem in quantum mechanics.
  • Another participant challenges the analogy, stating that the measurement problem is deeper than just experimental limitations and questions the premise that the measurement problem can be solved.
  • Some participants argue that the analogy implies local hidden variables, which have been disproven, and emphasize the need for clarity in the explanation of measurement.
  • One participant introduces the quantum model, explaining that particles behave as waves and that the wave function collapses upon measurement, linking this to the Heisenberg Uncertainty Principle.
  • There are differing views on the effectiveness of the analogy, with some suggesting it needs further development and clarification.

Areas of Agreement / Disagreement

Participants express disagreement regarding the adequacy of the analogy used to explain the measurement problem. There is no consensus on whether the analogy effectively captures the complexities of the measurement problem, and multiple competing views remain regarding the nature of measurement itself.

Contextual Notes

Participants note that the definition of measurement is not straightforward and that there may not be a distinct measurement operation. The discussion highlights the unresolved nature of the measurement problem and the assumptions underlying various interpretations.

i tried to explain for some one how we can solve the measurement problem and i went like this

imagine your self in a room and in this room you don't have any sense so you can't see hear touch smell or even taste

but you have a prob attached to your brain but if you don't do the measure you won't be able to know about a man that he is in the same room with you [or woman] so for you

the person for you are possibly in any were in the room in the same time because you can't see him or feel him

so he/she is probably in every where for you
you can't know where she is without doing the test

and this is the same for the atom if i do the test measure i will be able to know all the functions of it [location ,…etc]

and the reason is so obvious it is too small for us even for the smallest instrument.

is it good

IMHO, no.
 
This description is instrumental "is too small for the smallest instrument"
The problem with the measurement is much deeper.
 
I think analogies can sometimes be useful aids to understanding.I can sort of see where you are going with yours but perhaps you may wish to clarify it and develop it further.

why no?
 
hagopbul said:
why no?

Several reasons. The most obvious being that we don't know what a measurement "is" (there is a mathematical definition, but it is not at all obvious how that translates into what we do in experiments), or even if there is such as thing as a distinct measurement "operation". We DO know that is it far more fundamental than it just being about experimental limitations (the "size of the probe" etc).
Hence, the the basic premise of the explanation -that we know how to solve the measurement problem- is flawed.

I would say... not quite, but for a different reason. You are explaining a situation where there is a definite person there with a definite location, and you are just unsure of where the person is. This implies local hidden variables. Local hidden variables have been disproven.

There are a few different possible descriptions of what actually happens that depend on your assumptions.

The quantum model explains that every particle behaves as a wave and its wave function collapses when you try to catch an observable. Since you can get more than an eigen value the observable would have a standard deviation and this brings to the Heisenerg's Uncertainty principle that states that no instrument would be able to measure position and speed perfectly for any particle.

no i am not

i am saying there is 2 humans one is me and the second are in the room but i can't see him

not that i am not sure where he is or not if i do a test i will see him
no test he is not in a specific location
there is a possibility that he is in any where
