  1. Yes that much seems to be agreed. It is certainly more theological in style than the synoptic gospels: the "Word" in the prologue, more worked out ideas about the Trinity, etc. And it has some extra stories, I think, that are not in the others, e.g. the woman taken in adultery.
  2. Well it is interesting that the English translation seems to come out the same in different versions of the bible, which is far from always the case. But your view that St. John's gospel was written by a theologian is intriguing. There is certainly a distinct whiff of theology-building in it, which distinguishes it from the synoptic gospels. However I was not aware that the authorship of this gospel had been established with any certainty. From where do you get this information about an Alexandrian?
  3. Quite right! I had overlooked this.
  4. That's anthropomorphising, though: typical for YouTube videos but not good science. It's nothing to do with whether there has been any conscious observation. The issue is whether there has been an interaction with them or not. You can't observe a system without interacting with it, as a rule.
  5. It depends what you mean by "inexplicable". The behaviour observed in the double slit experiment is just as predicted by quantum theory, so it does not pose a problem for the theory. The problem is to envisage how to interpret what both theory and experiment say about the nature of things. So it is more of a philosophical problem than a science problem, really. If one belongs to the "shut up and calculate" school of (non-) interpretation, there is no problem at all! https://www.math.columbia.edu/~woit/wordpress/?p=9649&cpage=1
  6. Where did Jesus say he was not from this world? So far as I recall, he said, according to St John's gospel, "My kingdom is not of this world", (John 18:36) which is very different. More generally, almost all the information about Jesus that we have comes from religious texts (the New Testament), with very little corroboration from independent sources. That includes the accounts of miracles, which are reported events contrary to our experience and our science. So how do we know we can trust these sources?
  7. I was not aware that radical scavengers would actually increase risk of cancer. Surely it is the reverse? Do you have a link to an example of a study showing this? My understanding of the position was more or less as explained here: https://www.nccih.nih.gov/health/antioxidants-in-depth. viz. antioxidants in the diet are generally protective, but there is no evidence that further supplements add to that protection. Note this refers to what is apparently a considerable body of research, though it does not provide the specific references.
  8. In the same way that a tiger is bunch of forest plants, light and shade, you mean? And in the same way that you are asking these questions in good faith? 😁
  9. You have just told us they are mantises. Now, perhaps you can work out, from this Wikipedia article: https://en.wikipedia.org/wiki/Mantis whether or not a mantis is a plant. Can you manage that?
  10. Yes I've been thinking about that, and I'm sure he as as well. In the information age, and as an actor, he will I'm sure be well aware of the impact that a dramatic public confrontation with his potential executioners could have - a bit like Yeltsin with the tanks. If they gun him down in cold blood, that will put Putin and the Red Army beyond the pale permanently and will ensure a rolling resistance movement against the occupiers for years to come. If they are wise they won't do that. But he may not want to be taken alive, for fear they may torture him, to or use his captured family against him to get him to surrender. A grisly choice. Putin wants him dead, I have no doubt, more than ever now that he has thwarted the original plan. Zelensky has his place in history already, though.
  11. Yes, it's hyperbole. One has to understand Zelensky has an agenda, which is to bind the fate of Western Europe, and the EU in particular, as tightly to Ukraine as he can. His (wholly unrealistic) request that Ukraine be allowed to join the EU on an emergency basis is part of the same thing. The guy has his back to the wall and is pressing all the buttons he can. He's been calling everyone, including the pope, to drum up support, and trying everything he can think of. I take my hat off to him for his astounding energy and bravery - he knows he's dead when the Russians get hold of him - but one has to aim off a bit when evaluating some of what he says.
  12. Is it also the case that Li is used because of the small size of the ion, which enables it to form reversibly the intercalation compounds with graphite and CoO2 etc that are used in the Li ion cell? I don't know much about the battery chemistry but I can imagine a small ion being less disruptive to the structure of the electrodes, as it enters or leaves, than a larger one would be.
  13. Why don't you leave, then, and we'll all be happier? Win-win.
  14. None of this makes sense. But if you are river a.k.a current, that's not a surprise. An amber warning light to that effect has come on. 1) Metals take part in chemistry just like any other chemical substance. "A metal has nothing to do with chemistry" is an absurd statement. 2) If they did not take part in chemistry, a lead/acid battery would not work. Such batteries rely for their operation on electrochemistry, in this case the reversible reaction between Pb (metal) and PbO with H2SO4. 3) The transmission of sound waves in water is not a chemical process. If you have a source that says to the contrary, I'd like to see it. 4) Uranium is denser than lead because its atomic nuclei are more massive. The nuclei play no role in chemical reactions. Chemistry is all about the valence (outer shell) electrons. It is the therefore the number of atoms and the behaviour of their valence electrons, not their mass, that is responsible for the energy change obtainable from the chemical reaction in a battery. 5) The notion of a battery that might last "long enough to replace fossil fuels" is nonsensical. Batteries are a temporary energy store that needs to be recharged. 6) John Hutchison [sic] , i.e. not "Hutchinson", is a crank and self-publicist whose ideas don't work: https://rationalwiki.org/wiki/John_Hutchison
  15. So you simply dismiss my correction of your wrong statement by saying "even so"and just repeating the silly error. This is a waste of time.
  16. It hardly needs saying on a forum like this one, but your post is idiotic. Your "e" is "E", meaning (rest) energy. E is proportional to m, c being constant. Furthermore m is mass, which is not how heavy something is and thus does not depend on the force of gravity.
  17. I'm not a smartypants, though it looks as if you may think you are. Offhand, I can see no reason to think U would be an improvement over Pb in a battery. Its chemistry is quite different from that of Pb, it is even heavier, making power to weight ratio even worse and even depleted U is radioactive, making it unacceptable in domestic or road transport use. The fact that the end product of its radioactive decay (after numerous intermediate steps) is Pb is irrelevant to its chemistry.
  18. How can a speed be a particle, godlike or otherwise?
  19. Light is not energy. Light has energy. Energy is a property of a physical system. It is not "stuff".
  20. Then why present a conclusion, effectively accusing the science of being slipshod, before you have gathered the evidence? That is bound to invite criticism.
  21. Try this: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2911546/ I quote: "The effect of gross changes in vitamin K intake on anticoagulation is a classic. Since the early years of warfarin use myriad case reports and case series have described decreased anticoagulant response due to sudden excessive vitamin K intake. The causes were usually vitamin K rich, vegetable-based, weight reducing diets and food supplements or multivitamins. The culprit amounts of vitamin K consumed ranged from 25 to 6000 µg day−1, but other causes for therapeutic failures were not always excluded [28–31]. Excessive anticoagulation has also been described after unrecorded dietary modification or discontinuation of multivitamin use [31, 32]. Suggest following up these references if you are interested. But I would observe you did this with climate change as well. You jumped to the conclusion that the findings were an "assumption" and that some crucial piece of experimental work had not been done, when the problem was your own lack of understanding of the relevant science background. I suggest you would do better to ask your questions before you start drawing conclusions that there is something wrong with the science.
  22. It is well-known that Vitamin K plays a role in blood clotting, in that if you have a deficiency then you may find your blood does not clot properly: https://www.nhs.uk/conditions/vitamins-and-minerals/vitamin-k/ The interaction between Vitamin K and warfarin is explained here: https://www.ihtc.org/warfarin-and-vitamin-k I am also aware that warfarin is one of the trickier anticoagulants to use, as the dose has to be carefully adjusted for each patient by monitoring its effect. So it is not altogether surprising that altering vitamin K levels by the use of supplements is not a good idea if you are on warfarin. P.S. But see also the more technical reply from @Prometheus which came in while I was writing the above.
  23. I asked you for evidence for your assertion that anticoagulants are widely prescribed in order to counter excess Vitamin K. I think this is completely wrong, you see, so I'd like to understand where you got this idea from so that we can get to the bottom of it. What you are now saying is something entirely different, viz. that people on warfarin may be advised not to take Vitamin K supplements. I trust that you can see the difference between the two. If you can't then evidently we need to discuss it further.
