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

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 righ

I like this. Someone at MIT apparently had very similar thoughts. I'm still waiting on cheap betavoltaics though.

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,

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.

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 "n

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.

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.

Just curious how you rationalize time-crystals with this definition of dimension.

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 p

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 a

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.

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

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
