  5. I explained the two cases, so to say that you only have your own concept to work with isn't actually the case, is it? It's pretty clear he was wrong. By the very definition of the word, something that was established with evidence cannot be dogma, since it was not laid down by an authority, nor is it considered incontrovertibly true. Born was an expert in physics. I am unaware of his expertise regarding dogma. I think I know what he meant, and he would be correct, but dogma is not the right word. Because you are only considering one meaning of the phrase. As I've explained, it is not an appeal to expertise, despite your assertion, since it's not a matter of physics. I made no such assertion.
  6. John Harmonic has been banned for an egregiously inappropriate response to moderator feedback, on top of his failure to embrace the concept of this site.
  7. I pointed out before that there are two different ways that "questioned" is being used. By mixing the two, you are engaging the fallacy of equivocation. Also the fallacy of argument from authority: just because Max Born said it does not make it correct. In the sense that Phi used, Born is not correct. Even in the other sense of the word, I would argue that he is not correct. Trivially so.
  8. I did not claim otherwise. Since you do not appear to have noticed, my objection is to your claim that we can't reformulate an hypothesis. (the ontology can't increase) "Plenty of things are abstractions" ≠ "all things are abstractions" Also, physics is a part of science, but not all science is physics. Shall I draw you a Venn diagram? Would that make this clearer?
  9. That's not how we do science. Expanding the number of possibilities is perfectly normal. Plenty of things in physics are abstractions, and not things that necessarily exist as physical entities. (electron holes being one of them. Phonons. Photons.) Yes, exactly. You adjust the background hypothesis. But you said we could not do this. That it could not happen. "could not have appeared in any background assumption or auxiliary hypothesis" (emphasis added) There is no "derivation". This isn't a math problem. It is a fact that neutrinos were predicted before they were experimentally confirmed, and the predictions were based on existing data that had inconsistencies in it, based on what could be observed.
  10. Ontology is philosophy. We are talking about science.
  11. Yes, this is what everyone has been saying. What is the distinction that you are drawing here? It is lost on me. You claimed "could not have appeared in any background assumption or auxiliary hypothesis " and yet here we have this as a background assumption, leading to the prediction and discovery.
  12. I had science in mind, and not just math. You lose something when you try and reduce this to an algebra problem. Science uses math, but it is not just math. It's all in how you set up the problem. You say nothing has changed in the problem. But this is science _ we do a measurement, and find that x is not 3. It is 2.5. We rewrite the equation 2x + y = 6 and conclude that y is 1. We would then go and do a measurement to confirm that y is indeed 1. It's still math — we haven't changed that. It's the realization that there are two variables, not one, and writing down 2x = 6 was not encompassing everything. You seem to be suggesting that because we had confirmed 7 planets that we were not allowed to write down an equation that had 8 planets to see if that were a better fit for the data. Which is preposterous. And yet, that's what happened. Your hypothesis does not match with history. Ergo, it is false. It is amazing that you can say that you can't measure something in a system by measuring everything else involved in the system, and solving for the unknown. Because in my first postdoc, that's exactly what we set out to do. It's hard to measure neutrinos, so we measured the emitted electrons and the recoils of the daughters to deduce the neutrino spectrum. But you now tell me we could not have done this.
  13. ! Moderator Note This is a science discussion forum, not a conspiracy site. Take this nonsense elsewhere.
  14. But that's not naive falsification. NONE of the example given above are examples of naive falsification, as you have described it. And so here you argue that naive falsification is in effect, when I thought we agreed that it wasn't. Which position are you arguing? Who are the people who are insisting this? Are they perhaps made of straw? Major paradigms perhaps, but for lesser ideas it happens regularly. One has to consider that to become a major paradigm, there must be considerable evidence that supports it. For hypotheses without that support, experiments that fail to corroborate will relegate it to the trash heap much faster. Chances are few people hear about it, because such work is rarely published. Nothing surprising here for anyone familiar with science, and some of this has already been noted in this discussion.
  15. Then why bring it up? What other reason do you have for mentioning it, if you are interested in what scientists do? (and this is somthing you agree they ought not do , and don't do) And you then proceeded to argue a different point. Right. And this is what Reg is missing. If relativity were wrong, odds are very, very good we would have already noticed it. So we can proceed under the provisional thinking that it's correct, but also knowing that if there were a problem, then it will manifest itself in experiments that rely on it being correct. Making every experiment that relies on a theory an implicit test of that theory (i.e. questioning it) even if the purpose of the experiment is not an explicit test to see if the theory is valid, because we assume it's good (i.e. not questioning it)
  16. Testing a theory and someone being hell-bent on changing it are two very different scenarios. The only one pushing this naive falsification model is you. It's a strawman. You seem to be using "questioned" in a different way than everyone else. Your "naive falsification" would have us dropping every theory with a single anomalous result, as I discussed earlier. What actually happens is science checks to see if there is an explanation consistent with the mainstream theory first. Otherwise we would be dropping basic concepts every so often, only to reinstate them later. It would be a mess. Sorry, I should have written "questioned" so as not to confuse you. It's being used in at least two different senses in these conversations. I had thought the context of the paragraph in which that statement appeared would suffice to make clear how I meant it. But I was wrong.
  17. To some extent that's true. Show that relativity is wrong and a whole lot of stuff comes crashing down. But it has to be wrong for that to hold, otherwise it's adjustments, as you say. Merely showing limitations of the theory, much like the limitations of Newtonian physics, failing at large speeds, or GR not being compatible with QM at very small scales, does not make the model wrong.
  18. And those headlines are just for direct tests. What of the thousands of science papers published every year? Or just the workings in a lab that fall short of being publishable? The clocks I work on wouldn't function as advertised without QM and relativity working. We get people here claiming relativity is wrong and there is an aether, and yet I know that's not possible because I can do something simple like align a laser into a single-mode optical fiber and have it stay aligned all day, something that would fail if we were moving through an aether. To claim otherwise is to ignore they ways that science is interconnected and how it rests upon its foundations.
  19. I don't see the distinction you are drawing, but yes, Phi answered the question that was asked. So you are bringing up a different topic, and yet claim that Phi gave an incorrect answer. The best you can say is that it is an unanswered question. There is no guarantee that you will be able to collect data for any arbitrary set of conditions, but that is not required. It doesn't stop some people from demanding it, of course, but they often have an agenda (in my experience) Gravity is not questioned, either. You reach a point where the weight of evidence is sufficient that it's a waste of time and effort to confirm the basic theory. You then move on to more advanced topics — but that doesn't mean that you have stopped testing the theory. It just means you have moved on to indirect tests, i.e. where the experiment would fail if the underlying paradigm were wrong, and will only succeed if the new idea (based on that paradigm) is correct. We see this all the time in physics. You don't need to confirm e.g. time dilation with every experiment, but can run experiments that would fail if relativity were wrong. It's a matter prioritizing your limited resources. The smart money is on a well-tested theory being right. You don't abandon that theory based on one outlier of a data point. We didn't chuck relativity in the trash when the Gran Sasso experiment indicated superluminal neutrinos, because we had over 100 years of experiments, combined with a solid theoretical framework, telling us that relativity is correct. By the time we'd gotten there, a contradictory result became an extraordinary claim. Extraordinary claims require extraordinary evidence, and a single experiment isn't that. Nevertheless, relativity was being tested with that experiment, even if the purpose of the experiment was something other than testing relativity.
  20. So in what way does this not agree with Phi's response, that current science is questioned all the time? That the answer is often "yes, current science is consistent with what we know" does not mean that it is not being questioned. We only occasionally find answers that require adjusting the current paradigm.
  21. JoeH banned as yet another mpc755 clone
  22. dhimokritis has been banned as a sockpuppet of Kramer
  23. electricalelectronics has been spam-banned for posting vulgar and pornographic material. Apparently he either had a meltdown after being warned about some marginal posts, or was planning on being a jerk all along. Spam-banning removes all of his posts. Apologies if this disrupts any ongoing discussion, from before he decided to react like a child.
