  1. Right, "we, the people". These people. Yes, this is my point.
  2. True. It has three different meanings because it is grammatically incorrect. However, we interpret it and pick one meaning in spite of it being grammatically incorrect.
  3. Talking about meaning in language (rather than language acquisition / learning), here is a message that syntactically and semantically can have at least three different meanings, but I am quite sure that we all agree on one when we see it on a street:
  4. It turns out that their are at least four domains of studying meaning in linguistics: syntax, meaning of a sentence; semantics, meaning of words; pragmatics, meaning of a message; discourse, meaning of an exchange.
  5. In the real life conversations, in many situations, language only connects knowledge of one person to that of another, without actually passing much information. Here is an example (from Widdowson) of an extremely short conversation, which it nevertheless sufficient for both the participants and the readers to get the whole meaning: HER: That’s the telephone. HIM: I’m in the bath. HER: OK. The meaning behind this exchange is: She makes a request of him to perform action - He states reason why he cannot comply with request - She accepts reason. Otherwise, these are just three unrelated statements.
  6. Meaning is in our head. Language is one of imperfect tools to communicate it. "Time flies like an arrow; fruit flies like a banana." [Oettinger]
  7. I try to understand how the two generals paradox relates specifically to language and at all to meaning. Isn't it a general communication issue, such as e.g. synchronization of databases update?
  8. This item in the news has attracted my attention first because it reminded me of a banner on the walls of my biology class in HS, with the quote by F. Engels, "Labor Made Us Human". That Engels' speculation AFAIK never had any scientific support but was good for Marxist propaganda. Now this other narrative appears to be a result of sampling bias. This is interesting by itself. But, I also have a question. Even if there were a correlation between the dietary change and anatomical changes in human evolution, how a causal relation between them was deduced? “Meat Made Us Human” Evolutionary Narrative Starts To Unravel (scitechdaily.com)
  9. I suspect that if I try to explain what is wrong about their believes, the only result will be that I will become a part of the conspiracy of the established science. I've got already a question from another relative about how can I support the lies regarding alien colonies that have been discovered on Mars. At least, they are all vaccinated - it could be worse.
  10. Thank you. You have articulated very clearly why it'd be useless or counterproductive to try to correct their mistakes. There certainly are emotions and psychological needs driving this endeavor. At least, it doesn't seem to be harmful, so why not to let them enjoy themselves? Maybe some of their "patients" will get a placebo effect? I guess, I will politely reply that I can't judge it because it is not my area of expertise.
  11. This physics professor describes his hierarchy of Framework >> Theory >> Model. Theory is a framework applied to a specific context, model is a theory with external parameters plugged in. Might be useful for this discussion. See the lecture between 14 and 22 minutes:
  12. A relative of mine has sent me their website asking for my opinion. After I've stopped laughing, I've decided that the only thing I can do is to ignore this request. If you have a better suggestion, please let me know. Here it is: CLO Life. Note to admins: I am not promoting this in any way. This is just for fun.
  13. In the words of Pauli, "Das ist nicht nur nicht richtig; es ist nicht einmal falsch!" "It describes an argument or explanation that purports to be scientific but uses faulty reasoning or speculative premises, which can be neither affirmed nor denied and thus cannot be discussed rigorously and scientifically." [Not even wrong - Wikipedia]
  14. I don't see such a "list of requirements for new theory" serving any purpose in science.
  15. A state of two electron system is either factorizable into tensor product of the individual electron states, or it is not. In the former case, they are not entangled and each one has a definite state. In the latter, they are entangled and don't have individual states. Measurement of any of them changes the state of the system: it becomes factorizable, they become unentangled, and each gets an individual state.
  16. After reading and thinking, I'm getting a "third" answer. It is not Yes or No regarding the OP question. My feeling rather is, Doesn't matter because humanity will not do it anyway.
  17. Requirements 1 and 2 are not absolute either. For example, Newton's theory contradicted observations of perihelium of Mercury for centuries (requirement 2), but this was not enough to reject it. GR has singularities which can be easily turned into mathematical contradictions (requirement 1), but they are considered being out of scope of the theory's applicability, not enough to reject the theory.
  18. No, they do not. When you measure x2=right, electron 1 is not entangled because it was already measured (z1=up). So, at this time its x1 can be any, left or right, independently of the measurement x2.
  19. What is determined is z of electron 1 and x of electron 2. Let's say the measurements were: z1=up, x2=right. Now measure z2. It can be up or down. Measure x1. It can be left or right. They are not entangled anymore and uncertainty holds.
  20. When you measure any of them, they are not entangled anymore. So, any measurement of one electron doesn't measure anything about the other. Each has the normal uncertainty.
  21. Take a spring. Let's call it's length = total length - sum of widths of the coils. When it squeezed maximally, its length is zero. It has non-zero energy there. When it relaxes it expands, so the minimum energy is at the length greater than zero. This spring has a very real existence

    Altshuller, the author of TRIZ (the method), was a science fiction writer before he made himself busy with TRIZ 100%, some time in the sixtieth-seventies. He published his stories under the pseudonym, Altov. But the story and the writer you remember are unrelated to him, I'm quite sure.
  23. Nothing slows down free fall. A matter falling into a black hole will change its shape, becoming "spaghettified." Anyway, it reaches singularity very fast. For example, in the supermassive black hole in the center of the Milky Way it will be a matter of seconds.
