  1. So you thought your paper would get a better reception if you pretended it was written by a third party. I see. And you think that deception is OK, apparently.
  2. Interesting idea. I don't know whether signs of resistance to particularly virulent diseases might be recognisable in the genome. Perhaps @CharonY would know. But food shortage in the cold winters of N Eurasia may well be what bred lactose tolerance in only the people living in that part of the world. I wonder when cheese was invented. That must have been a crucial step in winter provisioning. But I am leading us off-topic for the thread.
  3. Hmm, I didn't know hydroquinone could be used for that. It's a mild reducing agent (oxidising to benzoquinone), but I see it works as a skin lightener by decreasing melanin production in some way. Not clear how exactly. I do recall the ads for skin lightening concoctions when I was in Dubai in the 80s, aimed at the substantial population from the Indian subcontinent.
  4. I presume you mean in science, given the context. I would say by considering observations of nature and learning the theories that account for them, and then by either making new classes of observation that go beyond what these theories account for, or by forming hypotheses, testable by observation, that account for observations that the theories do not cover adequately.
  5. That is really interesting and thought-provoking. It is also somewhat reassuring, for those of us worried about the value to be placed by business - and wider society - on the human intellect in the future.
  6. Very interesting indeed. And yet another zoonotic disease of course, something many of us are more aware of nowadays than a decade ago. But, to be clear, this is not the origin of Yersinia pestis itself, just of the strain that gave rise to the Black Death. There have been earlier plague outbreaks in human history, e.g the Plague of Justinian, in ~500AD. And according to Wiki, there is DNA evidence of Yersinia pestis infection in specimens from the Eurasian Bronze Age, back to 5000BC or so.
  7. I see that on this thread you claim to have "found" this paper, by one Frank Lombard, while searching for something. But in a later thread you reference another paper, by the same Frank Lombard, while claiming you wrote it. Why the deceit?
  8. This looks to me like tendentious language. Life experiences can't "program" you. They happen to you. A "program" presupposes a programmer, i.e. an entity with intention, acting on you in some way. What you make of experiences is up to your own (independent) thought processes, surely? As for the idea of consciousness being what's left over, after all the measured reactions to influences are accounted for, that does not seem to be how a doctor, for example, would determine consciousness in a patient. He or she would do that by means of an expected (measurable) reaction to a stimulus. So I don't think your conception of consciousness works. It's far too narrow.
  9. I should have thought that if the followers of Euclid could have read about Al-Jabr , which includes completing the square to solve quadratic equations, it might have moved both algebra and geometry on significantly. The Greeks worked on conic sections, after all, so the algebraic expression of a parabola as a quadratic equation would have rung a lot of bells. Coordinate geometry, instead of waiting for Descartes, would have taken off almost 2000 years earlier!
  10. Consciousness is not a part of physics. You may have fallen victim to the tiresomely widespread misconception that a conscious observer is required to "collapse" the wave function in quantum mechanics. This is wrong. Ken Wheeler is obviously quite crazy. The passage I quoted in my earlier post is just meaningless word salad. We can put you onto proper definitions for terms in physics if you need help, even though, ahem, Google is your friend.😁 But to be honest I don't know what you are doing on a forum like this. Anyone who quotes Wheeler as an authority is going to have an uphill struggle to be taken seriously.
  11. So you retain the wave character of QM evidently: you still associate momentum with wavelength and you retain the idea of a Fourier transform relationship between position and momentum. But the"mechanical trade off" you mention is exactly the conventional explanation of the uncertainty principle - and that's why "the universe refuses to tell you" both position and momentum at the same time. So, leaving aside for the moment the the detail of solitons vs. ordinary, dispersive wave packets, haven't you simply hit on the conventional model of QM here? I confess to being a bit uncomfortable with your reference to "strange, unexplained physics". I am not aware there is much of that, or any at all in fact. What we have is some difficulty in philosophical interpretations of QM, but the model appears to be self-consistent and accounts perfectly rationally for all the observations, doesn't it?
  12. Wave particle duality and the so-called quantum measurement "problem" (of which Schrödinger's Cat is just one illustration) have nothing to do with relativity. So you claim not only to replace relativity but quantum theory as well, do you? How do you account for Heisenberg's Uncertainty Principle, if you do away with wave particle duality and the associated Fourier transform relationship between position and momentum?
  13. OK, I don't know the area, though I've been to Naples and seen Pompeii, Herculaneum, Vesuvius, and Solfatara and the Phlegraean Fields. The places in Italy I have enjoyed the most have been Sicily and Lake Maggiore. Fabulous food in both areas (and great wine in the North from Piemonte) and Sicily is full of history and mythology. For example I was amazed to find a lake at the foot of the cliffs leading up to Enna is the location of the entrance to Hades where poor Persephone had to go for 6 months of every year, which upset her mother Demeter so much that the plants stop growing and we get autumn and winter.
  14. Ha, don’t we know it! I suppose I had in mind things like pneumonia, scarlet fever, typhoid, malaria, plus complications from measles and other childhood classics.
  15. You asked someone to send a POSCAR file. What were you thinking would be done with that when it arrived? Have you got access to VASP?
  16. Largely the same ones we have around us today, though we have eliminated a handful of them, e.g. smallpox.
  17. It is not fair to expect your readers to do the "research" for themselves. It is up to the person (in this case you) making a claim to support it with evidence. So you need to show your readers where in these logs, the evidence for what you claim is to be found.
  18. Seriously creepy. You seem to have gone a long way down the rabbit hole. No thanks.
  19. Oh so he's a known charlatan then, sort of up there with Deepak Chopra? I had no idea. I'll have to look out for him.
  20. No it was Maratea, on the sea - a last minute booking. The hotel we were in was over a tunnel carrying the coast railway line. Interesting, though winding, drive down the Amalfi coast to get there. Lots of limoncello, I remember. And my son was just over a year old and crawling/walking. The hotel staff made a great fuss of him - Italians love small children. Yeah I kind of like Amarone but it's very strong. Often a bit too much, I find. When I had my run-in with atrial fibrillation a few years ago I got very careful about alcoholic strength of the wine I drank, as I found I had to keep consumption at a sitting to 3 units max. (1 unit= 10g ethanol). So that pretty well ruled out things like Amarone, which is often 15%. I was better off with 12.5% Bx etc. I even got into German riesling a bit, which can be 8-9%, though tends to be a bit sweet - good with crab but not suitable for a lot of things. Even now that the AF is fixed, I'm still aware and a bit careful.
  21. Yes a snob of course. Must be. Only snobs take an interest in wine, after all. 😁 My son is doing a holiday job near Gavi and I thought I would try something from the region in case it gave us a talking point later - and perhaps he can find some. I do like nebbiolo reds very much but know very little about Italian whites - tending mostly to drink Chablis or Jurançon Sec, or sometimes white Bordeaux for chicken dishes (my wife was French). So it was nice to find a good one. That restaurant actually has a long and interesting wine list. Someone there knows his stuff and has put a lot of thought into it. They used to do an excellent Valpolicella Ripasso. But yes I've had Aglianico. I first came across that when we once had a holiday in a place in Basilicata called Maratea. I like it. But I admit I'm a novice with Italian wine. I believe the Primitivo grape from Southern Italy is identical to the Californian Zinfandel.
  22. Ken Wheeler seems to be completely off his trolley: https://kenwheeler.substack.com/p/the-universal-codex-in-full To quote a bit of this gobbldedook: All motion is the division & the disturbance of rest. The greater the division, the greater the resistance; this is Natural Order. Evil & motion divide what is Pure & Whole & generate resistance, which is evil, suffering, & dilution. To charge is meant taking motion & multiplying it by centripetal compression; this is called power or energy. To discharge is meant taking motion & dividing it by centrifugal expansion; this is called force. A base atom, or hydrogen, is a centripetal compression of light, which cannot propagate, such that its charge or frequency is so high. Frequency & charge/capacitance are one & the same thing. Higher frequency is higher capacitance. [continues] Er, yikes! It looks as if @Eric Smith is some kind of shill or alter ego for this nutter.😱
  23. At a local Italian restaurant last night I was very pleasantly surprised in trying a 2022 bottle of a Langhe white I had never heard of: Nascetta di Novello. Quite soft but with some acidity so in no way flabby, floral and herbal, hint of that waxy “petrol” note one gets with Alsace riesling. Seemed to go well with charcuterie and seafood. I gather this used to be a traditional grape in the Langhe in the c.19th, but had become almost extinct and was only recently revived by local enthusiasts. The vine is capricious, sometimes giving a productive crop and sometimes not, leading to a lot having been ripped up and replaced with the more reliable nebbiolo, which makes the great Langhe reds including Barolo and Barbaresco. Nascetta is thought to be capable of rivalling the much better known Langhe white: Gavi, which is made from the cortese grape. Nascetta now has its own DOC classification, so it is on its way back. So if, 20 years from now, Nascetta is all the rage, remember, you read about it here first! (I found a London wine merchant who stocks it and have ordered 6 bottles for my cellar, to do my bit to help their export sales.)
  24. You are using AI to bullshit @Radhakrishnan J , a new member, into thinking he is taking to an expert, when he is actually talking to a schoolboy. That is deceit.
