  1. Other than a modifier for nuts, I don’t know what “Deez” refers to.

  3. The nature of so-called "quantum teleportation" is very widely, very deeply misunderstood. Nothing is travelling "instantly", so nothing is teleported. Energy, of course, cannot be teleported either. What these experiments do is build highly correlated pairs of particles, and keep quantum coherence for incredibly long distances. They can then "switch off" coherence, so to speak, and can select sub-states completely correlated to each other. That's very impressive in and of itself, but no teleportation AFAIK. I wouldn't call this "teleportation", and I don't know who introduced that term, but it's a misnomer and it causes confusion to no end. I for one would prefer that scientists used a more understated vocabulary. But it seems to be the case that the more sci-fi it sounds the more hype it's going to stir. I think that's unfortunate. No, Star Trek is not around the corner. I wish it would.

  4. That is contradictory. On more than one level I might add.

  5. I don't know anything about this myself, but I did find this article by a wood panel manufacturer, who talks about the effect of pH of the wood on curing of adhesives:https://www.wbpionline.com/features/ph-and-why-you-need-to-know-it/ If you are interested in veneers, it occurs to me that you too may be concerned with adhesives.

  6. Unless they're told not to, but these people are mostly, complete bar-stewards and, so, don't give a shit what you just said...

  7. My grandfather was a carpenter, my parents still have a few pieces be made. About a week ago I finished my first dovetail joint made out of an old spice rack. I've now started my second one. I don't have great ambitions at the moment. I'd like to get to a point where I can make a reasonable box.

  8. I'm 100% aligned with both Klaynos and Swansont above. It really depends on the details of the situation and varies case-by-case. There is no way to remain reasonable and rational when attempting to apply "one size fits all" thinking on this type of issue. It's also no longer "whistle blowing" when the information is being cascaded through external channels or media outlets without regard for the safety of our personnel or our country. If the internal processes (or local ombudsmen) in place to address these sorts of ethical issues have already been tried and failed, then it MAY be appropriate to take other steps outside the system, but this once again returns us to the "it depends on the details of each individual case" territory. After that, and beyond the process focused discussion, these decisions all occur within the subjective territory of what constitutes the "public good," and "which" public is benefiting or being harmed by the release / leak. This obviously will differ from one person to the next. Ask 10 people what's in the public good and you'll get 10 different answers. Finally, I'm also far less sympathetic to the leaker and their good intent / positive motivations when their source (and/or their funding) is from some other nation state which has a clear agenda... where the leak is basically being used as a soft / non-kinetic attack on another nation state or on democracy itself (like the Podesta emails or disinformation campaigns on social media, for example). Worse yet... even I myself am inconsistent on this subject within my own thinking. By example, I'd be far more open to an attack on another country launched by my own than on an attack launched on my country by another... or from my employer on to a competitor. This is anything but a simple question which leads to simple and binary yes/no answers. Nuance matters here, and the ONLY correct answer is that "it depends" and varies case-by-case.

  9. I don't think you can draw any single rule on whistle blowers. It'll always come down to a balance of what is for the public good and that is rarely an easy line to draw. The bulk release of illegally obtained information without review is likely to cross that line in most people's opinion. In the UK there are legal protections for public officials as long as they are acting in good faith. Which again will often be a difficult line to draw. To a certain extent you have to have confidence in the justice system.

  11. And here's a sketch of a pressure-fed hydrogen engine. No scale, but the dimensions I checked are all favourable. Only few injectors and streams are displayed. The many streams should join their divergents, and some hydrogen be injected where they don't. Angles between the streams shorten the engine, while slow upstream oxygen turns easily. The oxygen injectors could protrude from the side instead, reach nearly the centre, with shorter injectors between the longest ones. This circulates less oxygen in the head where the fuel might freeze, but this doesn't happen at RD-170's gas generator. Whether the many hydrogen moles ignite in the warm oxygen? The progressive evaporation gives a chance. Staged injection can help, or a pilot flame can burn a bit of dense fuel with lower ignition temperature like Pmdta or Diesel oil. A small compression wave could converge to an ignition point. An optional atmospheric insert, no displayed but very useful, can be ablatively cooled. I like the RD-0120 discardable inner divergent in this role because the flow is stable at intermediate pressures too. Pressurizing helium can be stored in the oxygen and dense fuel vessels, as graphite here doesn't favour spheres much. The vessels are bigger, but remain much smaller than the hydrogen tank(s). Some sprinkler provides isothermal expansion then. Or the hydrogen can keep helium cold in a small separate pressure vessel to save good mass. Marc Schaefer, aka Enthalpy

  12. A woman was at her hairdresser’s getting her hair styled for a trip to Rome with her husband.. She mentioned the trip to the hairdresser, who responded: ” Rome? Why would anyone want to go there? It’s crowded and dirty.. You’re crazy to go to Rome .. So, how are you getting there?” “We’re taking BA,” was the reply. “We got a great rate!” “BA?” exclaimed the hairdresser.. ” That’s a terrible airline. Their planes are old, their flight attendants are ugly, and they’re always late. So, where are you staying in Rome ?” “We’ll be at this exclusive little place over on Rome ‘s Tiber River called Teste.” “Don’t go any further. I know that place. Everybody thinks it’s gonna be something special and exclusive, but it’s really a dump.” “We’re going to go to see the Vatican and maybe get to see the Pope.” “That’s rich,” laughed the hairdresser. You and a million other people trying to see him. He’ll look the size of an ant. Boy, good luck on this lousy trip of yours. You’re going to need it…” A month later, the woman again came in for a hairdo. The hairdresser asked her about her trip to Rome “It was wonderful,” explained the woman, “not only were we on time in one of BA’s brand new planes, but it was overbooked, and they bumped us up to first class. The food and wine were wonderful, and I had a handsome 28-year-old steward who waited on me hand and foot. And the hotel was great! They’d just finished a £5 million remodelling job, and now it’s a jewel, the finest hotel in the city. They too were overbooked, so they apologized and gave us their owner’s suite at no extra charge!” “Well,” muttered the hairdresser, “that’s all well and good, but I bet you didn’t get to see the Pope.” “Actually, we were quite lucky, because as we toured the Vatican, a Swiss Guard tapped me on the shoulder, and explained that the Pope likes to meet some of the visitors, and if I’d be so kind as to step into his private room and wait, the Pope would personally greet me. Sure enough, five minutes later, the Pope walked through the door and shook my hand! I knelt down and he spoke a few words to me” “Oh, really! What’d he say ?” He said: “Who the Fuck did your hair?”

  13. "Imaginary" is just a word. Don't read too much into it. "Real" is just a word, don't read too much into it. "Exist" is just a word..., and so on. If a circle really exists, then complex numbers really exist. If a circle doesn't really exist, then complex numbers don't really exist. Can things kind of exist to you, instead of really exist? "Use" is a far nobler verb than "exist." You can use complex numbers and understand many things with them as a tool.

  14. OK so you have described how you see it (your problem) so no apology needed. I don't know about you skills since although you say you are not a scientist you clearly have a reasonable measure of knowledge and understanding. Your phone is probably not the ideal recording device, however. You need a gadget or gadgets mechanically coupled to your floor or other parts of your apartmenet structure. Such a device is called a seismometer or an accelerometer for higher frequencies. https://www.google.co.uk/search?q=seismograph&sxsrf=ALeKk01_X_O2wDFnlkHwFbfzkOrsxMsN9A%3A1618773670675&source=hp&ei=poZ8YNTqJq6JlwSKvrywAw&iflsig=AINFCbYAAAAAYHyUttRlHmbsMbU_OlZSqZM_jiiz5lU1&oq=seismograph&gs_lcp=Cgdnd3Mtd2l6EAMyAggAMgIIADICCAAyAggAMgIIADICCAAyAggAMgIIADICCAAyAggAOgQIIxAnOgsILhCxAxDHARCjAjoICAAQsQMQgwE6BQgAELEDOgUILhCxAzoICC4QsQMQgwFQ2ApY-iBgtD1oAHAAeAGAAegKiAHaPZIBCzMtMS4wLjIuMy4zmAEAoAEBqgEHZ3dzLXdpeg&sclient=gws-wiz&ved=0ahUKEwjU1fDswYjwAhWuxIUKHQofDzYQ4dUDCAg&uact=5 Although these can be very expensive simpler ones can be bought cheaply or even made by an amateur. They are indeed made as projects in some schools. This would give you an indication if there is something there and a permanent record of it as well. Another possibility for a trial would be an old fashioned gramophone cartridge with its stylus resting on a hard surface fixed to the floor (eg a ceramic tile) and connected to a data logger. It all depends upon you skillset and purse.

  15. Lunatic argument, did not show me who refuted this study, what methods were used to refute, and what date they were refuted, just claimed to be old "probably refuted". And he also said that I have agendas at the end. LMAO However, as I said before, recent studies are in the text above, if the child cannot find it without the help of an adult, I can do nothing. I don't even have time for that.
