Have I answered your question concerning why the Lorentz transform uniquely satisfies the principle of relativity, assuming Maxwell? And did you have some point to make by this question?

To tell you the truth [ :) ] I agree with you to an extent. Tom Roberts will also tell you that we do not, in physics, know anything about nature itself. We only have models about nature and we rate the performance of models according to certain criteria that are central to the scientific method. I would claim that this method does manage to secure some connection between the models and nature that is beyond opinion, conjecture, beliefs, propaganda, and so on. I would further comment, though, that there are lots of different kinds of statements we call knowledge, and only a small fraction of them are what would be classed as scientific theories. Furthermore, there are whole realms of investigation that might result in knowledge that are wholly unsuited for scientific methodology. An example would be most one-off events, because science strongly favors the reproducible. > > The "sun came up" statement was an attempt to find something that would be > hard to argue against but it is a part of the "prediction theory" that > says the sun comes up every day.

Do you want specific examples? This is where the control of variables in an experiment becomes especially important, as is the analysis and estimate of the size of the effect due to uncontrolled variables, which is often quoted as an experimental uncertainty in the measured result. There are also indicators of signal significance above recognized backgrounds, as well as other statistical methods to evaluate the confidence that the match to theory is not an accident. These methodologies are common in biology as well as in physics, especially where there are populations studied in their native environments. > > To get closer to what I think might satisfy YOU, I opened up that quantum > mechanics (text, 668 pages so its not a comic book) book authored by > Morrison (c 1990, so its not obsolete) to the chapter I read just > recently on the wave-particle duality.

This quoted sentence almost exactly mirrors what I told you about particles and waves. Electrons and light are neither particles nor waves, but are some OTHER kind of entity that exhibits some particle- like properties and some wave-like properties. I just wrote the same thing a slightly different way. In my mind, I am in agreement with your chosen author. Is there a distinction you see that you would like to elucidate? PD

I like that sentence. Because, if you completely agreed with me, then I'd think there was something wrong. Nobody agrees completely with me, I don't agree with anyone else completely. I appreciate 'gradations' and overlap in "understanding." > Tom Roberts will also tell you that we do not, in physics, know > anything about nature itself.

There are nice things about science, and I'm grateful that a lot of us are out of the "mystical" and the "superstitious" lines of thinking (eg. the gods are mad because we did something wrong, and brought earthquakes, thunder, floods, famine, disease, etc). Reproducible? Yes, your experiments have to work. >> >> The "sun came up" statement was an attempt to find something that would be >> hard to argue against but it is a part of the "prediction theory" that >> says the sun comes up every day.

Not unless you want to see those other 2-3 pages. I'm planning to read more of the book. The guy is very nice about "interpretation" and being frank and undogmatic. I think I can get a lot out of the text passages without having to struggle with the equations (its been decades since I did any algebra & calculus, so I'm too rusty). And, I have paged through the book over the last 1-2 weeks. But, I also have a large stack of other books to read, too. And, anytime you want a quality perspective on globalization economics, let me know. This is an area where I've done substantial reading (at least 20 books on economics overviews [by serious big names] and economic history). Globalization economics is seriously full of hype and hucksterism; much worse than E/R problems. > PD > > >
