  1. My understanding is that at any instant, they are measuring local time, which varies depending on the local conditions. Or to put it another way, they are measuring time, in the location in which they exist, and in the frame in which they are stationary and not accelerating. And since you can use that time to calculate how time behaves in any other set of circumstances, when you measure time in one place, aren't you effectively measuring time for the whole Universe?
  2. I think that those things would have some effect, but nowhere near enough for you to survive. I believe from memory that a falling body reaches about 200 kph maximum. But a hell of a lot depends on the ratio of weight to surface area. If you were very thin, you would reach a lower final speed than a big fat man. And the type of clothes you wore could cause you to fall slower or faster. Hitting a roof would surely kill you, but not as badly as hitting tarmac, if the roof was thin and gave way. You'd be dead, but less of a mess. ☺️
  3. Your best chance would be to land in a snow drift, and for your descent to be nearly parallel to the inclination of the snow. That could happen if the slope was very steep, and the wind blew you so that you are falling at close to the same angle as the slope. If you were VERY lucky, you might survive falling through thin branches on a steep wooded slope, under similar conditions. I would guess that your chances would be less than one in then thousand, though, but people have survived falling from great altitudes under those kinds of freakish circumstances. Falling off that bridge though, I would say that nothing could save you, but for some sort of improvised parachute.
  4. One possible adverse result of eliminating parasites is that it could upset the ecological balance in unforeseen ways. If you eliminated the mosquito in Alaska, you might enable Caribou populations to explode, causing over-grazing and extinctions of some of the food plants. I would still eliminate the Irish Midge, if I had the chance though. I owe them some retribution. And the Irish tick, they are everywhere in boggy land, and can carry some pretty nasty bacteria, if you are unlucky. They call them Skirthorns locally. I don't know if they are a sheep tick or deer tick, but they will stick into anything they can, cattle, dogs, people, and probably mice and voles, I'm betting. Horrible things.
  5. Feudalism and slavery were pretty much the same thing : Quote wikipedia : " As with slaves, serfs could be bought, sold, or traded (with some limitations as they generally could be sold only together with land, with the exception of the kholops in Russia and villeins in gross in England who could be traded like regular slaves), abused with no rights over their own bodies, could not leave the land they were bound to, and could marry only with their lord's permission. " https://en.wikipedia.org/wiki/Serfdom Tibet was feudal right up to when the Chinese took over control in 1951.
  6. I believe that the Knights Templar operated the first recognisable banks, which helped them get enormously wealthy, which in turn led to their downfall. From memory, they issued the first cheques, for travellers to use en route to the holy land, to fight in crusades or to visit holy sites. Kings used to have a Crown Treasure, which they could take with them as they travelled around their realm. It's said that King John lost his Crown Jewels in a pack train across quicksands and marshy lands. Maybe they got caught out by the incoming tide. He was engaged in raising support for a civil conflict, and jewels and gold and silver were the trusted currency at the time. The barter system could be used for affairs of state, as well as buying turnips.
  7. Who are you to judge how anyone else uses the word? 😊
  8. I won't ever be that rude about you. ☺️
  9. The title is self explanatory. To me, some of the examples are obvious. The smallpox virus, the Leprosy bacterium, those parasitic worms that get inside your eyes, the syphilis bug, the world would surely be a better place without them. But would you let the mosquito go extinct, when so many animals eat them? Or would you just exterminate the malarial parasite? I personally would let the warble fly go extinct tomorrow. I'm sure others would disagree, but I can't think of any redeeming features of it. But, if you started killing off parasites, where would you stop? I suppose all predators are sort of parasites, including us humans if you stretch the word far enough. Would the lack of misery of the victim be the difference? That's how we tend to operate.
  10. I judge for myself, and sometimes offer my opinion. That's as far as it ever goes. I never claimed any more than that. Sometimes I offer links, but it's only to help other people make their own judgements. I don't recall ever putting myself up as a judge on anything. I'm not going to start writing "in my opinion" if front of every post. I take that as already understood, by most people reading it.
  11. I'm with you on that. To me, extinction is the enemy, and if we can prevent it, it doesn't really matter how. Of course, you don't want to advance the extinction of one species, by trying to save another, so it has to be done carefully. But if you can keep the remaining species alive, until the human population gets under control, then that's a result.
  12. Where a mistake is an option, I wouldn't even class that as a UFO sighting. To me, the term implies that some effort has been made to investigate, and the normal explanations have been examined and excluded. Like I said above, I wouldn't personally count a bin bag in the wind as a UFO sighting, even if some people got excited about it.
  13. That's just definitions. That might come under the widest definition of UFO, but it's not how I use the word. I tend to keep it for flying objects that defy normal observations of flying objects in some way. It's how most of the public use the expression. Of course, what's a UFO to one person might not be to someone else. When I said that the first and most likely explanation is that they are lying, I'm referring to the cases that apparently can't be explained. That's a real UFO to me. Not a bin liner in the wind, or a vague light in the sky.
  14. I'm not saying that Obama knew the future, when they were urging on the Arab Spring movement. His team might have imagined a glowing Middle East, full of democracy and progress. If they did think that, they failed dismally, and couldn't have got it more wrong. The more cynical side of me thinks that they reasoned that anything that destabilised the existing powers is good for Israel. Especially Assad in Syria. While Syria is being destroyed in a vicious civil war, it's less of a threat to the interests of Israel. So it's actually been a good war for the States, despite all of the public wringing of hands. Edit correction: Not a twelve year gap, I don't know where I got that idea from. But Obama had been in power 2 years, when the Arab Spring kicked off .
  15. I take a daily pill that combats acid reflux, like an awful lot of other people. I don't know the exact mechanism, just that it works exceptionally well, and other people also find them very effective. Apparently, they form a sort of "cap" over the stomach contents, preventing them from coming back up the throat. If I forget it for a few days, I will notice the throat gradually a teeny bit of soreness. I can't say that my sense of smell gets any better on it, but I do notice some odd smells that seem to persist throughout the day, just getting the tiniest whiff now and then. I thought it was something coming from my skin, but if I put a hand or an arm to my nose I smell nothing, so I'm leaning towards the idea that it's a phantom smell. Nobody else notices. It's a bit weird. Something else that happens now and then is that a smell persists in my nose, even though the source is long gone. The other day, I drove back from an airport trip, and called in at the services half way home, just for a pee. I could smell doughnuts in the services, but that smell stayed faintly with me all the way home, another twenty miles, when I couldn't possibly be really smelling it. I just quickly nipped in and out, just used the gents. Surely not long enough for the smell to impregnate my clothes.
  16. There are some girls who always fall for "bad boys". Just as there are some girls who always fall for other girls. And girls who always fall for tall guys. And some for older men. etc. etc. The "bad boy" phenomenon, in my opinion, is just a trait like any other, but one that gets noticed, whereas the boring traits do not. I have five sisters, and none of them chose "bad boys", but that's boring, so you don't make up an imaginary rule for it. Edit: One factor that might operate though, is that good looking guys might be able to indulge their egos more, in the knowledge that if they get dumped, they are confident of moving on to the next willing "victim". So being an attractive male might make you more inclined to act the "bad boy".
  17. There's a twelve year gap from George W to the "Arab Spring" in 2011. Obama came in in January 2009. I'm afraid his prints are all over it. And there's no mystery why. Anything the US does in the middle east is either for oil money or to bolster the interests of Israel. It's the tail that wags the dog. .
  18. I think you need to re-check your dates.
  19. What these countries are like now, makes the previous era of the Asad and Gadafi seem like the good old days. https://petapixel.com/2016/08/02/26-photos-show-war-changed-syria/ Those pictures should be labelled "before and after Obama". Anybody else want liberating ?
  20. You have to apply some kind of simple logic to these UFO claims. I love a mystery, but I'm also well aware how people can hallucinate, at odd times, without any input from illicit drugs. Which is more likely, a hallucination, that is very real to the victim, or a visit from aliens ? Obviously, the answer is hallucination, so without any harder evidence, that should always come before the alien explanation. But personally, I think the very first go-to explanation for any UFO claim should be that the witnesses are lying, and/or that the person reporting second-hand what alleged witnesses said is lying. There's a huge amount of lying happening every day. Some people just can't help themselves, and those of us who are unused to their ways are often easily taken in. You often hear people discussing these claims asking " why would anyone make that up? " and that's the biggest weapon of the liar. They often throw in details that actually go against their claims, to make people think, "a liar wouldn't have said that " . They are devious buggers. The biggest logical argument against UFO claims though, is common sense. If we humans eventually got the technology to visit another world, that was inhabited by a more primitive civilisation, what would we do ? Creep around in secret, just appearing as a Will-O'-The-Wisp to one or two individuals? I don't think so. And of course, there is the glaring fact that as smart phones get better and better, and billions of people are carrying high quality video cameras with them, the UFO sightings seem to be getting fewer and fewer. When they should be all over the media, in HD video. So as I said, I love a good mystery, but not the obvious hoax kind. Rule out lying and hallucination, and produce some proper evidence, and I'm interested.
  21. When you say freehand, I'm assuming you still have a guide to follow the edge with ? I'm just contemplating a few end plates, so if I can get a reasonable result, time doesn't come into it. I noticed that they don't supply any bits with it, so it's on to ebay once I buy one. I was surprised how much they cost, some of them cost more than that router. No wonder they don't give you any. I think I would need something like this, but in quarter inch shank : https://www.ebay.co.uk/itm/2pcs-Carbide-Alloy-Endmill-Router-Bit-Woodwork-Cabinet-Door-Milling-Cutter-Tool-/283610856366
  22. They probably have a slightly different business model in the US. I just looked, and found this one at Aldi. Any good ? https://www.aldi.co.uk/ferrex-600w-palm-router/p/018278285168900
  23. Thanks. I'll start looking. We have a german supermarket over here called Aldi, and they occasionally do routers and accessories for very good prices, but you have to wait till the offers come around. Yes, that F looks bang on. My phones got a great camera, but I still couldn't get it to show that profile. But the F looks perfect.
  24. Even the S shape that it has? It's hard to pick out, it's a bit like a human shoulder, over the shoulder and then upwards up the neck. Would I need to get a router bench to get a straight finish?
  25. Would a router be able to produce the edges on the end plates of a concertina as shown in the pictures? I've never used a router, but would like to be able to make replacement ends similar to the one shown, (which is about 130 years old). I have a scroll saw for the patterned ends, but don't know what to get for the edges. For size, an edge is 9cm and it's 16cm across. I tried to show the profile, it's more of an S shape than a simple upward curve.
