It is trivially possible to make any statement meaningless by randomly replacing words, which is why Distler's "argument" is not an argument, it's just the last resort of someone who hopefully realized he is wrong. "Lakatos wrote the following about his methodology of scientific research programmes, in his eponymous text on page 51:A 'model' is a set of initial conditions (possibly together with some of the observational theories) which one knows is bound to be replaced during the further development of the programme, and one even knows, more or less, how. Just in case that was too complicated: Yes, of course it applies to the multiverse of string theory. Once he's done, he rests while checking the news... and his heart sinks. This is not quite the same as a prediction.Lamb showed there is a resonance in the microwave frequency with an electron in an atom. Surely these problems of comparing scientific theories, and the demarcation between science/pseudoscience cannot be easily disentangled. If you assume a model and rate of spread and mortality rate then you can't get away from predicting earliest cases. And those engineers, who only knew the formal theory and did not have a good physical understanding behind it, in general did not find solutions and created incorrect results. Making excuses now and holding on to same R0 and CFR is like trying to invent inflation to account for spread of universe while not being able to explain the temperature uniformity.

"This statement is only meaningful if you define what it means for something to "exist" in the scientific way, which I have done above. Please correct me if I am misguided here in this assumption. The last third of this comic definitely resonates with your post I think, regarding modelling, assumptions, predictions etc.https://fivethirtyeight.com/features/a-comic-strip-tour-of-the-wild-world-of-pandemic-modeling/. The whole fucken reason the damned book is called "Lost in Math" is because of people like Distler who are mathematical Platonist and do not even realize that this is a belief.You get exactly the respect you deserve. The only other physicist/mathematician/cosmologist that I know of who does this is John Barrow ['New Theories of Everything, or 'Book of Universes'] but I don't think I've seen you mention him.

It’s the hypothesis that has the highest explanatory power. When theories contain explanations that rule out things, it is this falsifiability in the sense of knowing what you should not see that adds to explanatory power. I think you owe me an apology.">Third.

The guys had been smart and quickly learned how to bend physics to match their setup and subsequently won a Nobel prize. This doesn't mean it's irrelevant or useless, but it does mean that it necessarily only a rule-of-thumb.As to dark energy and dark matter, how can these theories make predictions? We need something like it, or an extension of it, to turn “Explanatory Power” into a quantifiable and measurable metric.One approach I have mentioned is Compression; in theory there is a maximum lossless compression factor for any given document based on its inherent Information Content. This is only the case if it does so in a simpler way. The standard model works just fine without unification.

In case you still did not understand this. "Climate change is observable. Toegut,In your example it is once again unnecessary that the alternative theory actually makes *predictions* for observations yet to come. Steersman,Well, for one there is a value in understanding the past even if it does not help you shape the future. All you have to do, as I have mentioned in my examples, is to have assumptions that were superfluous to begin with.

But when you say: “That's the purpose of science after all, to describe nature”, then I clearly disagree. And it is ultimately a value decision, so not one that we are going to answer, here or elsewhere. I get a problem if theories that despite having turned out to be useless grow to large, tax-paid research programs that employ thousands of people, as it has happened with string theory and supersymmetry and grand unification. I think I disagree with you that predictions are overrated. You means that you know what the good science is. There is no reason that nature should actually be described by a theory of everything. When I think about a scientific theory, and its predictions.

Precisely the hallmark of stagnation in fundamental Science(what is happening now) is the lack of empirically validated predictions, and that reason is the underlying topic in Stacy McGaugh article(Predictive power in science isn’t everything. string theory, so saying this may give a git of the wrong picture for people not in the field. Likewise, if I have to judge a person (or philosopher) on what they believe about a theory, then I would be in a similar position. The data *weren’t* available before the theory, so...? "As I explained in the blogpost that you are commenting on, the answer is yes. This assumption is untestable and unfalsifiable. She currently works on dark matter and … The required explanatory power needs to have certain quality and it might be hard to define it satisfactorily.

Why not pick on archaeologists for a change? Therefore it seems to me that one should not be dictating process or conclusions in the other. This is the real war to be fought now.Paul Steinhardt, one of the founders of inflation, now calls inflation a fixer and claims that this theory is not scientific, because it can prove everything and therefore nothing. In May, Sabine Hossenfelder explained why Roger Penrose should win the physics Nobel prize, and today he has Posted on Tuesday, Oct 6, 2020 8:05AM by … In order to solve now the summation problem, Einstein was forced to invent his known space-time using the metrics mentioned above.

Take the statement "A person whose height exceeds 6 feet is tall." We need a theory of quantum gravity because general relativity and the standard model are mathematically incompatible. Inventing a new particle will lead to a potential new measurement or product in a particle collider for example.As Professor Feynman said, "First we guess, then we compute the consequences and see what it would imply".https://youtu.be/b240PGCMwV0RegardsAndrew. A better summary would be "theory of everything may turn out to be unnecessary/misguided", because there is no proof that this is not happening either, so saying that it is unnecessary and/or misguided is too strong. To the extent that the theories which physicists have come up with were falsifiable they have been falsified. It’s like claiming that a study must be wrong because the lead author has a conflict of interest. Given that the issue isn't going to go away it suggests that scientists may have to learn political and media fighting skills which might be a little uncomfortable for those of us that prefer sitting on fences or studying change rather creating change. Dr. It is the case that SUSY potentials of superfields can model many things. This is to my knowledge a cultural phenomenon. But, I might be wrong, so these things are not settled at all.

However, I agree with you that one way of judging a theory is by its ability to explain observations. In a situation where string theory is dominant and the history of that theory (among their things) is A. hoping to find evidence fore super symmetry in CERN (and having not done so, demand a CERN 2 and then a CERN 3 and it is to be foreseen the claim will at the end be that you need the energy present at the Big Bang to see the super symmetry.B. A god that is omniscent and omnipotent is not understandable, and an explanation that is not understandable is not a real explanation.I think I agree with you, but again with a different slant, on this post about predictions.
