Stern-Gerlach for Spin 1 Particles

In summary, the conversation discusses John Conway and Simon Kochen's 1-0-1 theorem and its relation to quantum mechanics and the concept of free will. The theorem is seen as a simpler version of Bell's inequality, but it only uses standard quantum mechanics. The conversation also mentions that there are different interpretations of quantum mechanics, but they all lead to the same predictions and do not rule out the idea that free will may be an illusion.

Y'all might find this interesting. John Conway and Simon Kochen's 1-0-1 theorem.

I have no questions. Sorry.

I don't see what is new. The 33 axes look like a simpler version of Bell's inequality, fine, but they used standard quantum mechanics only. We know several interpretations of quantum mechanics and we know all of them lead to the same predictions (and some of them are deterministic) - you cannot rule out interpretations with thought-experiments within standard quantum mechanics.

The fact that free will is an illusion (for reasonable definitions of "free will") is not new either.
 

1. What is the Stern-Gerlach Experiment for Spin 1 Particles?

The Stern-Gerlach experiment is a landmark experiment in quantum mechanics that demonstrated the quantization of angular momentum. It involves passing a beam of particles with spin 1 (such as silver atoms) through a magnetic field gradient, which causes the particles to be deflected in different directions based on their spin orientations.

2. How does the Stern-Gerlach Experiment work?

The Stern-Gerlach experiment involves sending a beam of spin 1 particles through a spatially varying magnetic field. The magnetic field causes the particles to experience a force that is proportional to their spin orientation. This results in the particles being deflected in different directions, with each direction corresponding to a specific spin state.

3. What is the significance of the Stern-Gerlach Experiment?

The Stern-Gerlach experiment was a key experiment in the development of quantum mechanics, as it provided evidence for the quantization of angular momentum. It also demonstrated the concept of superposition, where particles can exist in multiple spin states simultaneously. This experiment also laid the foundation for many other quantum phenomena, such as entanglement and the measurement problem.

4. What are the implications of the Stern-Gerlach Experiment?

The Stern-Gerlach experiment has important implications for our understanding of the fundamental nature of matter. It showed that particles have intrinsic angular momentum, or spin, and that this spin can only have certain discrete values. This has led to the development of the Standard Model of particle physics, which describes the fundamental particles and their interactions.

5. Can the Stern-Gerlach Experiment be applied to other particles besides spin 1 particles?

Yes, the Stern-Gerlach experiment can be applied to particles with different spin values, such as spin 1/2 particles (such as electrons) or spin 0 particles (such as photons). In fact, the original experiment was performed with silver atoms, which have a spin of 1/2. The results of the experiment would be different for particles with different spins, but the underlying principles and concepts remain the same.
