No direct spin measuremnets. I can show you the latest review article on the subject of the spin of the free electron. Conclusion: it HAS NEVER BEEN DIRECTLY MEASURED. Many physicists will say it has been empirically measured, but the expert in the field says that is FALSE. It is hoped that technical problems previously preventing a direct measurement of the spin of the free electron will be solved within 1-10 years. Hope this helps to clarify your thinking.

No direct spin measuremnets. So, you're challenging the basic conservation laws, and Noether's theorem.

No direct spin measuremnets. Stern-Gerlach, fine structure in atomic spectra, Zeeman splitting, nuclear resonance... That NMR and MRI machines work should tell you something about our knowledge of the spin of elementary particles. > > I can show you the latest review article on the subject of the spin of > the free electron. Conclusion: it HAS NEVER BEEN DIRECTLY MEASURED. You could but you won't, because it won't say what you want it to say. > > Many physicists will say it has been empirically measured, but the > expert in the field says that is FALSE. Who might this expert be, and what are his credentials? I somewhat suspect the 'expert' is a guy with a web page who says something that makes sense to you and nothing else. > It is hoped that technical > problems previously preventing a direct measurement of the spin of the > free electron will be solved within 1-10 years. Wow, one to ten years? That's a pretty wide time frame. Do you even know what the 'technical problems' are? I wonder what problem you think measuring the spin of a free electron solves. > > Hope this helps to clarify your thinking. > > A little knowledge can be a dangerous thing. As evidenced by people like yourself who think they have absolute command of physics because they read a few coffee table books many years ago. > > RLO > www.amherst.edu/~rloldershaw

You scale the numbers to whatever you think works, and make arbitrary choices of parameters. You even have the case where several of your n's 'correspond' to entirely different particles. You are not doing physics, no matter how hard you've tried to convince yourself that you are. There's a reason you are posting here instead of giving lectures, publishing articles, and going to conferences. |
