Many Worlds Interpretation and Coffee

Click For Summary
SUMMARY

The forum discussion centers on the Many Worlds Interpretation (MWI) of quantum mechanics, specifically regarding the implications of simultaneous events, such as everyone having coffee with everyone else. Participants clarify that MWI does not imply that all possibilities are continuously occurring, and free will is not factored into the equations of quantum mechanics. The conversation highlights the complexity of the Schrödinger equation and the philosophical implications of interpreting quantum mechanics, particularly in relation to the concept of infinite possibilities and limitations.

PREREQUISITES
  • Understanding of Quantum Mechanics principles
  • Familiarity with the Schrödinger equation
  • Knowledge of the Many Worlds Interpretation (MWI)
  • Basic grasp of probability theory in a quantum context
NEXT STEPS
  • Research the implications of the Schrödinger equation in quantum mechanics
  • Explore the philosophical debates surrounding the Many Worlds Interpretation
  • Study probability theory as it applies to quantum mechanics
  • Investigate the relationship between free will and quantum mechanics
USEFUL FOR

Physicists, philosophers of science, and anyone interested in the implications of quantum mechanics and the Many Worlds Interpretation.

Well, then Bohr definitely wrote only about true things. :biggrin:
Except the Bohr model of atom (with the so called "old QM"), which is clear but not true.

What if I tell you that I have a theory that solves all these questions at once? :wink:
Oh sure, butter me up with something I won't be able to follow. I'm holding out for comprehension.
OK. let's see it, maybe it will work as a soporific.

Is it just because of the existence of atoms, or because you don't think that the axiom of choice represents a physical choice?
I tend to view physics as finite, in the sense that any experiment only has a finite number of outcomes. The mathematics and theoretical physics extrapolates this to countable and uncountable infinities. A classical example is modelling a body as a continuous mass distribution, even though the physics is a large, finite number of particles.

In QM you can practically only carry out a finite number of measurements, so there is always a mathematical extrapolation to a continuous wave function defined on an uncountable set of points.

The extent to which the underlying reality is infinite is perhaps unknowable, as we will only ever have a finite set of data.

In particular, I can't see that the axiom of choice would be relevant in a physical situation.
