  1. Depends on how you define "extraordinary"? A big point to consider is something ballistics looks at: overpenetration. Going high-end fraction of C in speed means that there's no time for "shockwave" to really form and transfer energy well. That's why a really-fast really dense bullet is in a lot of ways less dangerous to flesh than a slightly slower one that will deform. It's all about how much energy you can actually transfer to the target. .99c and massive means ENERGY, but it doesn't have much ability to transfer that energy. When you end up with something like 40 miliseconds of total "contact" time spread out over a fairly large area geverything around that area Immediately gets "jiggled" and goes to highest-possible energy state (plasma) and probably gets a bunch of linear momentum added too. But that's a very small fraction of the actual energy of the "bullet" in this case, even with some nuclei being unfortunate enough to meet up with other ones at speeds that should overcome strong-force and do the annihilation-dance. Speed of sound is the general speed you'll see energy get transferred in matter, and solid stuff has FAST speed of sound to suck more of that interaction energy outwards, but .99C is...just way outside those specifications. Most of the planet will just not even notice something went through it. I'd wager the same something moving at 0.01C to 0.1C would do a lot more spectacular damage to a planet by the sheer fact that it could actually transfer it's momentum rather than just...ignoring the valance bubbles and leaving them shredded in it's wake. Anti-matter? Anti-tungsten would be a riot. Anti-neutronium would be particularly vile since it would not "miss" anything even if it was much-much smaller by volume to same mass. A slow-moving Strangelet would be the most terrifying unobtanium or phlebotinum.
  2. I don't think there'd be a real difference no matter what angle that kinda object collided at, nor where it collided. At that speed it should have already crunched into a sphere from it's own perspective and a rather elongated oval from the earth's That kinda speed there would be just pure annihilation in a direct path. If you're looking for some fancy words and pipe-dream knee-jerk physics (cause at that speed we're in "best guess" territory).. -there would be some fusion/fission events and plasma discharge from the atmosphere, probably with enough heat and force to strip the atmosphere right off that area of the planet within minutes...but there wouldn't be time for that before... -the mass would go though the planet in practically zero time(~ 0.00004 seconds), causing fusion/fission events the whole way though and eject from the opposite side. Think gunshot wound from a FMJ going though ballistics gel but the long hole would still have matter in it...matter going though a fair amount of fission/fusion events. -Probably no appreciable deceleration of the object itself but likely it gives enough force to the stuff where it passed though to put a super-sonic geyser in place and eventually pump a continental chunk off into a different orbit around the sun over the next couple hours and weeks. -the forces holding the matter together in and just outside the direct path would not be enough to keep doing that very well. Massive ionic plasma discharges comes from both "poles" of the impact line. Sudden pillar of light from both ends, ground itself "glowing" for miles around. -a big old sudden jolt felt world-wide, just before two fire-storms of plasma rush around the planet from the impact-poles somewhere around the speed of sound, sterilizing everything in hot plasma-wash. -oceans probably don't completely dry up, but most likely boil around the top for a couple days as the heat radiates. -Lot of mixed H O Fe Si etc in pure atomic form reacting as it cools down from plasma being ejected from the active annihilation path over a couple months. -Hole would mostly fill itself in over a couple years, active volcano at both ends. -new tectonics for a couple millennia as things shift around. -earth and moon gets rings like Saturn for a couple more millennia -wait for life to condense a new non-reductive atmosphere and crawl out of the oceans. Again, the "hole" wouldn't really change much weather it hit needle-first or flat-side, but the energies of the interactions would probably go beyond vaporizing and into plasma-fying everything in a wide radius of it's path. The object itself would probably convert some mass to pure energy on its way though, but a good chunk of it would also likely just "miss everything" on it way though as well; since matter is mostly-empty and the normal EM holding stuff apart would be insignificant. It might realize it hit something and start to break-up on it's way out of the Oort cloud, though.
  3. I like this. Someone at MIT apparently had very similar thoughts. I'm still waiting on cheap betavoltaics though.
  4. Is this going to devolve into another one of those "Mankind could not find God, so they built One" things? I'm in favor of remote control of home and tele-presence tech, those seem to be the ones the OP is talking about. Convenient to be able to check-in on your assets at a whim. Internet Of Things leading to smart homes and smart cars that actively serve us will be great. I'd love a home that turned on my coffee maker as I was on the way home because it noticed on it's own the way I do things. The covid tracing apps on cellphones are another ambiguously useful extension of that IOT at work, right alongside dating apps that buzz in proximity. That's related to how everyone gathers a halo of technology-aids that make them who they are these days. Everything that you regularly use from a smartphone to PC to prybar to hair curler, it's all part of a philosophic concept of an "exoself." The technologies that are online are in a large part taken up as part of that exoself to exoself interaction between people. Considering how much of the data-connections online leverage this, I do see why OP is worried about "just a BIG BROTHER." Everyone and everything can look at your digital footprint (trash pile) even easier than your neighbors could open the bin and dig around (if they wanted to) in a physical sense. There's another layer of "digital ghost" and/or our "online trashpile" depending how you view stuff like old harddrives and social media posts made by the dead while they were living.
  5. sounds like you want membrane filtration or centrifugal sedimentation for 'big' particulates or oils. Then distillation (above post) to separate your salts. Note that you can use vacuum pumps like a refrigerator system to get the same kinda separation by varying boiling point and temperature for precipitation. edit: Just to clarify, that's the easy way to do it in your garage with low volume. High volume industrial has it's own specialized versions.
  6. https://home.howstuffworks.com/green-living/how-to-make-distilled-water.htm You have access to pots and ice, right?
  7. There's a saying from one of my modern heroes, Lawrence Krauss. I think It applies equally here as it does when I see people misinterpreting other things like gravity or electricity or magnetism from the incomplete 5th-grade science similes they remember. "The human brain evolved to avoid predators on the savanna, not to intuitively understand the laws of the universe" There are a lot of studies, both scientific and social, that try to determine why people make silly decisions or hold silly beliefs. The best reasoning I've come across is closely related to that above observation. The same "natural" neural hardware that kept our ancestors alive through short-term dangers really screws with the ability to tell truth from fiction and make long-term judgements that contradict short-term panic decisions. In the past that shadow-movement out of the corner of the eye could have been a predator about to pounce, so the ones who got frightened and knee-jerk ready to run or combat survived more often. There's very little downside to a false-positive in that scenario, but today that same wiring is probably what leads to ghosthunters and the rabbithole of other "seen but not really recordable" phenomena. Similarly the intuitive grasp of size & distance in the human brain can be boiled down to "bigger than me, needs two hands, needs one hand, smaller" and "in arms reach, within 10 seconds of sprint, farther." It takes training to be able to grasp sizes & distances outside of those categories. Most people who don't actively use dimensions in real-world applications cannot at a glance get anywhere close to the right measurements. Ask an average person how big their bedroom is they'll go "oh...kinda small" or "big enough for object, object and object." Someone in construction or some in real-estate will ballpark "around ten by twelve" or "100 to 150 square feet" (with the occasional few using meters). Dimensions take training to be understood. Dimensions that need optical assistance like microns or nano-meters compound this intuitive grasp problem many fold. "I can't see the holes" is the same as "there are no holes" to the savanna-brain, do not ask it to understand filtration, VOC, etc... on an intuitive level. It's just not going to happen.
  8. What kind of powder? What kind of foam? Depending on usage case the way you'd do that is different. You thinking like home made drywall, home made aerogell (water not really useful there) or some other use? Generally speaking if you impregnate the water with a large amount of gas with some pressure tricks you can then use other pressure tricks to make the paste "bubble" while it hardens. You could also do some additive chemical mixture stuff (like hydrogen peroxide) to generate your internal bubbles, but that might screw with whatever you're using the foam for.
  9. Another way to look at it: cells and batteries are just any (occasionally reversible) combination with galvanic corrosion(RedOx) potential. That is why the Voltaic Pile is a semi-modern bit of important history, and of course the great witchcraft of Animal bio-batteries as well. It's worth noting that when properly designed, a cell only "needs" one galvanic pole and the solution itself can be the second.
  10. Just curious how you rationalize time-crystals with this definition of dimension.
  11. Rote learning is actually quite beneficial for almost everyone AFAIK. It tends to make thing extremely boring but from what I know of how the brain works, constantly repeating an action or "skill" reinforces the associated neural pathways and makes it very likely to "stick." It's that same "use it or lose it" philosophy in action: constantly going over the process of maths reinforces the process and makes the brain consider it to be "important" so it's less likely to be discarded as "a waste of resources" to maintain. The issue with some rote often was/is concentrating on results rather than process. Just memorizing a multiplication table is far less useful than doing he actual multiplication itself by rote. (not to throw shade at memorizing tables, they are extremely useful as long as you already have the process itself ingrained by rote as well) Depending on what issues you and your doctor are trying to "buck" you really should try and track down that Australian documentary series I linked. They dedicate each episode to different areas of mental performance, the ways of benchmarking them, and ways to train and rehabilitate any that have atrophied. I stumbled across it a little while ago trying to put to words an issue I had noticed. I found out the name itself was "attentional blink." Ex:When I was much younger i could readily notice individual frames in a lot of media and to some degree notice scan-lines in CRT, but going back to the same old hardware out of a garage I wasn't able to perform at the same level. I could still notice the things that were probably happening by the "humm" of the electronics but not catch them as often(if at all) in the actual visual output. Quite an interesting thing that. I should probably be less lazy about the exercise regime I found to "fix" and retrain that. It's very much worth finding a way to watch the whole series and then check into the information they water-down for mass consumption. By hook or crook I highly recommend finding a way to get ahold of it. I personally think it should be mandatory viewing and yearly review for every single k-12 teacher.
  12. A lot of it has to do with neuroplasticity. Older people tend to lose plasticity, most likely as an evolutionary mechanism: it takes a LOT of calories to keep the human brain running, so any corner that can be cut to save a few calls here and there ends up being cut. Same way if you don't actively work-out, you lose your strength and muscle mass. Use it or lose it. There's an Australian documentary series that goes a long way towards "fixing" common issues. Some people(even kids) are just...deficient in plasticity. That makes it hard to learn and "make connections" in both the figurative and literal sense. Weather it's from some ASD issue, or a nutrient issue, or an injury. Narrowing it down to computers: They are so common it's crazy so kids will be exposed constantly, practice constantly, and form transferable skills. The point-and-click and "icons" are common "skills" between smartphones weather they're android or apple, computers weather they're windows or mac or linux, etc... Same time most of them will never see what a command-line is and be utterly frustrated if they're put in front of one, and don't even think of asking most people to program a register on an MCU as that's also not a common transferable skill even among modern computer programmers. Moving to generation-gap skills: Most modern kids cannot drive manual transmission. The very idea is frightening to them, so much so that a manual transmission is more effective than common anti-theft devices. A lot of them also cannot properly do things that used to be common knowledge like setting a choke or changing fluids; those are not really transferable skills from what they're exposed to, so stuff like electric mowers/clippers/blowers are more common and attractive to them. There's a whole library about that kind of stuff if you dig into it. So in short; old people that take to new things usually have some comparable skillset they already learned they can base things off of. Young people that just can't learn probably have an "issue" that needs treatment. A weird side-effect of the above: modern texting on cellphones often ignores punctuation. That has caused an interesting skillset division. Periods and proper grammar are perceived as "formal to the point of being rude" by a significant part of the upcoming generation. It's scary that movies and books predicted that.
  13. Wrong thread for this discussion T. There's a few that ARE right for it though. I will leave off here by saying "Natural" is NOT synonymous with "good" nuclear radiation is NOT synonymous with EM radiation(though it can result in EM radiation). Feel free to multiquote from here into another appropriate thread if you want to continue the discussion.
  14. 1st: You got an extra chance to prove you could follow the rules after...30-something times breaking them. Remember your dare? I do, but I still gave you a chance when someone asked for it. You just wasted it. Still I'll be a sucker and give you another length of rope. Either hang yourself with it, or use it to climb out of the pit. Go on. log back into your original account, it's also off ban so unless you waste this one last final chance you can use that to post. It's the LAST chance though, and ONLY available to the original account, not the sock puppets. 2nd: Taxation was around in Egypt. It was a lot worse than modern days too. Do provide the docs that make you think otherwise. (on your original account) 3rd: Random crazy claims and pseudo-threats aren't allowed. Especially from people on thin ice. Read the rules. Follow them. Or go somewhere else.
  15. Odds are "good" considering we've got monkies that can control robot arms with their brains, cyborg-robots controlled by rat-brain slurry, and proven deep brain electrode treatments just in the past 20 years. Impact I would gauge roughly the same as the internet. Interesting side-effect I could see would be from hackers "jailbreaking" their own lace to get high, or take better control of their various cycles (like sleep), or for nootropic brainwave functions. Could also be great for targeted anti-depressants or anti-psychotic treatments. Of course lace would come with some risk beyond the basics of inflammation, infection, etc... I'm almost certain the first few generations will have the same interference issues as old style pacemakers. Also only a matter of time before some troll figures out how to incite seizures through malware or whatnot. Flipside is of course detecting and preventing the same...
