  1. There were a good number who knew, and who did little things to fight against it. That is how my father escaped from landing up in a concentration camp, the nurses at the hospital he was recovering at helped him to escape, a few weeks before he was due to be transported to a camp.

  2. Used to ba a treatment for malaria to gradually give you larger and larger doses daily of strychnine, to the point it killed the malaria parasites in the blood, but not quite killing you, Then taper the dose off again over a few weeks till you were no longer taking it. done when the British army had a lot of malaria cases in the tropics, and no quinine to treat it otherwise.

  3. World production is also in the sub gram a year region, simply because a single gram has to be diluted down a billion times, to get the concentration down low enough that an automated machine can use a few millilitres of this, to make a thousand litres of solution, that will be put in 1ml ampoules for the surgeon to use. Yes the dosage is such that you can count the number of molecules used in each injection.

  4. My father left a Lancaster sans parachute, as it, along with the plane, were well ablaze. He woke up in an Austrian hospital 6 weeks later, after being found, apparently dead, in a snow bank under a pine tree. Morgue doctor listened, found a heartbeat, so he got a hospital bed. Back burnt all over, broken neck, broken jaw, broken collarbones, broken ribs, broken arms and broken legs, but he recovered well. He found out from the nurses that, once well, he was to be transferred to a concentration camp, Auschwitz, so decided, with a little help from the nurses, to escape, along with another British POW in the hospital as well. Borrowed an Adler staff car, and they went for the Swiss border a few kilometres away.

  5. Or, more likely than a tree in Ohio, a power company exec wanted to make a quick profit on power futures, and was driving the spot price up and up, till the grid overloaded, with too few power plants available to provide power input during peak power demand. One tripped out on overload, and the failure cascaded from there rapidly, as each successive grid section was tripping trying to either supply too much power, or to transfer too much power to areas that had suddenly lost the local plant.

  6. Funny, must be a US thing, because here rolls for hot dogs are sold in 6's or 12's, and the mystery meat fillings typically come in a pack of 12, 18 or 36, so you either stick 2 of the bready red or brown flavoured sticks in a roll, or buy 2 packs of 6, or a dozen. Then you find there is that thing that is canned sausage.

  7.  @tjj2040  Made it to the Swiss border, but they wanted to send them back as German deserters ( dad spoke fluent German, as he had been living in Germany till 1939 going to school there, but was in the UK when war was declared. British passport) so they hit the policeman and tossed his ink pot onto him, so they went up before a judge the next day instead. got the confirmation that they were UK POW's later on, and got repatriated to the UK. Every time he went to Switzerland after the war he had to tell the Customs that he had a Swiss arrest warrant, and explain the story again. If they asked he would turn and show his back, all one massive scar from the skin grafts the Austrian doctors had put there to save his life.

  8. Incidentally the jet engine efficiency you talked about is backwards, 80% or so of the power output of the engine is devoted to compressing the incoming air, with only 20% or so providing the thrust. Turbofans improve things by taking the incoming air, and using some of the power diverted to power the compressor to turn that, making for a much larger volume of air being used to provide both thrust and cooling, with only a small amount of the jet output being used to provide thrust then.

  9.  @civilwildman  Lack of quinine meant the doctors had to use alternative treatments, basically try to kill the parasite before killing the host.

  10. Funny enough the local factory used to be 50m away from the Hilton hotel. As I worked near there it was easy to tell which way the wind was blowing, though the Hilton was unfortunate in that it was pretty much downwind all the time. I like the smell, though the hotel did not, plus i used to go to the source every so often to collect yeast, and got to taste the freshly dried yeast, looking like cinnamon bark sticks, as it came hot off the drier, before it was blown up a floor to be ground up and bagged.

  11.  @limiv5272  To be fair, if a light cat landing on it would rip it out, then it was only a very short way from a gust of wind doing the same, and lucky nobody was on the ground where it hit.

  12. Will add that South Africa actually has now more households with microwaves than the number of houses with an electricity meter, simply because of the massive numbers of illegal electrical connections.

  13. Tastes about as similar to cheese as a cheap hamburger helper filled pattie tastes to the finest fillet. there are cheese spreads that do contain real cheese, they do taste a lot better. I just like the real thing though.

  14. Yes, on fresh bread, nice and thick. Small jar or large one, lasts the same time as well.

  15. Tiddles did a swan dive from 8 floors, onto the concrete pavement, after failing to negotiate a jump from one window to another. He survived, though he did break both front legs and his jaw. Lived a good number of years afterwards, just was very wary of windows then.

  16. Could be that, but a lot more likely to be environmental factors as well, that added to the dosage, plus exposure to chemicals, that inhibited the cell repair mechanisms, that were the cause. Live at high altitude, increased radiation from space, live by rocks emitting large amounts of Radon, increased risk. Live by large industrial processes, that dumped fine particulate matter in the air (coal, steel, oil refining, open cast mining amongst others) and water, or live down wind of large industrial plants, that emit waste gas and fine particles, some of which are radioactive isotopes, that are either natural or man made. Safest place to work is in the actual radioactive product industry, where they actively track down and monitor all sources of radiation. Had that, where the trigger was the road crew coming in, and triggering a monitoring well, as they had used a freshly crushed batch of granite, which had more than a little Uranium and Radon in it. The wash water, that they used to clean the dust off the gravel in the batching yard, before coating with bitumen, was a little above background level when they dumped it in a storm water drain, that was using the soak away the plant used.

  17. That shortage of aircraft is why my father did his pilot training in a Gypsy moth, as it was considered too old, too slow, and not at all capable of being a fighter aircraft. He probably also still owes then some money, seeing as he crashed it, after an engine failure during take off. They never asked him about that Lancaster he signed for though, that sort of fell apart around him by Lake Constance.

  18. The A10 fires the short bursts more due to the massive volumes of gas generated from the gun, which is ingested by the engines. Too much gas sot the engines flame out, because there is no oxygen in the compressed gas, and as well it is very good at stopping the engine flame front from burning, blowing it out the rear. That plus the recoil is attempting to stall the airframe as well.

  20. Just needs to be around March and April here, when at 10AM the sun is within the field of view of the LNB, and swamps the satellite signal out for an hour. Easiest time of the year to align a dish, without using anything other than your eye, just aim it at the right time to cook the LNB front with reflected light.

  21. Did get a few of those, dug out of a 1900's era rubbish dump, dug out to build a Hilton Hotel.....

  24. Best drunk when you are drunk, letting the good beer( if there is any such thing) kill your ability to remember taste.

  25. No real actively dividing cells, very good cellular repair mechanisms, and also very massive redundancy, so a few cells failing is not a big deal, the storage simply has slightly less detail on any particular event, and the repair mechanisms and cells can cope with that. You can lose hearing, as the ears do contain actively replicating cells, along with the cornea, hair and the mouth, as those surfaces are exposed to the outside world. The rest though is only slowly churning over with time.

  26.  @YoungWolffe  Still cannot stand the taste of pineapple, after 3 months of every meal tasting of it, including the coffee and tea.

  27. Funny, just got the 10mS dosage today, lying in a running CT scanner for a half hour, with the lead clothed radiologist busy using needles on me.

  28. Almost never had the PB&J, but enjoyed peanut butter and syrup, though I also have used a wide variety of other spreads to complement the peanut butter. Quite like it with a more tart counterpoint, so enjoy it with peanut butter and Marmite, goes well if you also add a slice of cheese there. Recently just the 100% rye bread, pure peanut butter and added butter, very tasty.

  29.  @Celica-DGM  Was not my cat, but the neighbour above. I just so happened to be at the ground floor when Tiddles completed his jump, and rushed out to find him, lying there. Picked him up gently, and carefully took him up to his owner, who rushed him to the vet. Next day Tiddles was wearing a pair of plaster casts, had a shaved jaw with stitches in there and was very unhappy.

  30. Well, the Kraft stuff at least is not a cheesy joke, though it has all the ingredients to make it one, just not apparently the cheesy part.

  31. That is why your typical X ray facility and dental office has a room that is lined floors, walls, roof and doors with lead sheet, to attenuate this. Also the windows into it are made with lead glass, which does the same, and the doors are lead lined inside. thing is, the actual clothing they use on you is not lead, but depleted Uranium in a large amount of cases, as it is a better absorber, and thus a lighter mass for the same protection. Coated wire woven into a cloth, 2 layers, so few gaps, and more flexible as well. Does need special handling for recycling though, which is why you typically hand in the old when you buy the new.

  32. Funny thing is here, not in the Netherlands, there is a very strong tradition of smoking the happy plant, and it is almost legal, or at least there is a lot of turning a blind eye to having it for medicinal purposes, and a very strong movement to have it declared as not illegal. Seeing as it is very common to find it growing wild, there is a lot of it around, and it does form a significant part of some rural areas for income in an otherwise poor place by growing it. Was getting a delivery last week, and the driver and loaders, from upcountry, were sniffing the air and commenting they like this city, as they could smell the happy plant, from people just walking past randomly smoking it.

  33. Funny enough when you go to the optometrist there are a few who have a CT scanner in the office, which is tabletop size, and which is able, after around 20 minutes of imaging through your pupil and the front of your eye, build up a remarkably well detailed image of the structure inside your eye. Includes the retina, all the blood vessels, the cornea and the lenses themselves, along with the pupil, and also the different layers inside the vitreous humour as well. Amongst it's abilities it can also be used to make a contactless measuring for a custom contact lens, as well as determine your optical script to a very high accuracy, as it knows all of the optical paths involved, and can calculate the required correction as well, even if it involves the lenses themselves not actually having simple curvatures on them.

  34. So that is why canned whipped cream is so popular..................

  35. Industrial PTFE sheet with a back etched layer is common as slip surfaces in machinery, where the brown back surface is there from the ion etching to allow adhesives to bond to the surface to allow you to stick them down to a backing surface. Otherwise you have to drill and use mechanical fasteners to hold down the sheet, or use a thick sheet of PTFE and clamp it down. The front surface is slippery, the back not so. However it has reduced heat resistance, but is commonly used as a backing to apply pressure to heat sealing, like in a bag manufacturing line, where you have a hot bar forming one seal in a bag, then it is filled with things like sweets and then hot sealed top and bottom using another hot bar and cutter to separate the packs.

  36. Yes, strong tea is the only way. The rest is like a canoe, very close to water. However due to time and other constraints I use bag tea a lot, convenient and I also drink it with or without milk, but definitely no sugar. As well the tea type is important, I prefer a stronger tea and also like earl Grey as a variant, plus locally grown Rooibos tea.

  37. More because a kilometer of lead might stop the more energetic ones, while for neutrino's a light year of lead might barely get noticed.

  38. Bananas don't last long enough in my house to get overripe. Do use the more ripe ones chopped up into chunks with some Greek yoghurt and a dash of vanilla to make a nice dessert though. For extra flavour add some whipping cream to the yoghurt and mix it up well.

  39. I can guess a lot of the odd writing came from recycled cloth bags that once contained staples, brought as relief supplies to the war ravaged country. You used to get things like flour, rice and other non perishables in either canvas or hessian bags, which were often repurposed as clothing, as there was no cheap readily available cloth. Only in the last 50 years or so did plastic packaging make the cloth obsolete, but you still get some industries that pack stuff in hessian bags, as the plastic ones react with the product, or are going to contaminate it. Thing in mind is bran for horses, which still comes in a hessian bag, as the horses can eat it as well without harm. They were great bags when empty, just wash them a few times with softener to get them a little less hairy.

  40. To be fair, all beer has, at some point, been urinated out. There is a definitely finite amount of water on the planet, and, as nobody as yet is making beer from cometary ice water, all water on the planet has, at some time or the other in the past, definitely been part of a stream of urine. Even if you were to take glacier water you will find the same, just that it was more likely to last have been urinated out, in a 21 second stream, quite some time ago, by some long extinct creature.

  41.  @orbwithinanorb  Look up the number of illegal connections, that are known about, and then compare that that most of those illegal connections the household will have a fridge and microwave oven, along with a TV set. 87% plus do not pay for TV, so you can make the assumption about the number of microwaves from that, as a Tv is a luxury while microwave is not.

  42. hot dogs, everything except for the last moo, squeal or cluck. May even contain meat.

  43. Had hard boiled eggs that were done so long the entire egg was green. We also found out that those eggs would bounce. We joked there were 101 things to do with them, 102 if the result was edible. The joys of bulk food, where they would only start the timer for 20 minutes after all the eggs were loaded into the 44 gallon cooking pot, and it had started to boil. end of 20 mins they would turn off the heat and start to unload. OK if you got the top ones, but not so good for those in the lower layers.

  44. Cloudflare using the same offices as Oracle had, who were the original ones to use them for that. however you would have had to pay Oracle to use them, so they only became popular once the patent had expired.

  45. All dental X rays use a gun, mostly because it concentrates the energy into the beam, so leading to needing to use lower dosage, and thus prolonging tube life considerably. Also the digital imaging can operate with much lower doses as well, and have a better response at this low dose.

  46. And the spambot and impersonator bots are active again.

  47. Fire hydrant outside between 2 pavement trees. Dogs use the trees and not the hydrant, watering the tree and the plants in the bed all the time, and none of them use the hydrant, because hydrant is set further back from the street where they walk, and the tree is very visible as an object.

  48. Really depends on the area what the markings are though. By me the base colour is yellow, and the ones with a blue top are simply to indicate that the supply line to them is HDPE pipe, and not the original asbestos fibre cement pipe. The HDPE was installed by hydrofracturing the old pipe in situ, then pulling the HDPE through the new cavity, so it is slightly smaller diameter.

  50. Not really needed with a well shielded gun, as it only has a very narrow collimated beam out the end, and almost nothing at the sides. The dentist has to wear the clothing and leave behind the shield, because he is getting exposed to all 3000 shots he does each year, while you only get the one per year. Way different total dose there, you get more from a kilo of bananas.
