>>8126516 If we're able to store information dense enough to be comparable with a black hole, we're certainly able to replace our squishy bodies with purely mechanical ones and expand the brain to cover a larger part of our bodies, or we can just get bigger bodies with bigger heads.
Hey, I recently did some tests for a government agency, among those tests were an intelligence test and in that test I got the question:
>"If you have a constant flow of water from a tap and you were to place an electrically charged bit of steel right next to waterflow, what would happen?"
I had some alternatives which I don't really remember, but some of them were: >The water will arch out toward the steel >The water will turn a different colour in the vicinity... Comment too long. Click here to view the full text.
So lets design a scientific way to try and observe this.
How would you do this? Have a bunch of people memorize a bunch of random things and check on them all periodically and then record the number of reported 'changes' every so often and compare the percentage of reported changes over time to see if there are any explainable spikes in the number of reported changes? Because of course its entierly plausible and inevitable that people will just remember things wrong, but if a bunch of people suddenly inexplicably remember a bunch of different things wrong at the same time, then its evidence of something?
What's the best psychological method to deal with fear of abandonment? I mean, I suppose it's something you develop when your mother transmits you lots of insecurity during your first years of life, and that will transform into general anxiety disorder, low self-esteem, depression and other illnesses. The thing is, once you know what's at the core of the problem, how do you recover? Is there any specific method?
I'd wager that the only way is to slowly force yourself into the situations where your fear of abandonment appears and then live through them rather than pulling back
only by continuously exposing yourself to these situations and finding that you do not get abandoned you'll change your innate emotional response and way of thinking
at least, that's one of the basic principles of cognitive behavioural therapy, that you have false, exaggerated or unreal cognitions, which we challenge/ease... Comment too long. Click here to view the full text.
Before the Problem begins, Omega uses godlike predictive power to find out whether you are a Switcher or a Stayer. Omega presents you with three doors. Two of the doors, if picked, will cause a trolley is to run over five people. Behind the third door, there is another trolley. -If Omega predicted you are a Switcher, it will run over ten people. -If Omega predicted you are a Stayer, it will run over one person.
Having picked a door, Omega now reveals that one of the doors you didn't pick would have been a Five-Person... Comment too long. Click here to view the full text.

Before the Problem begins, Omega uses godlike predictive power to find out whether you are a Switcher or a Stayer. But you cannot falsify until after the test.

But using a measuring system based on the number of fingers on your hand is equally retarded. When are you going to grow up and realize that 2's and 3's do a better job of defining reality than 5 ever will?
>>8125448 Popsci is good to get people an initial interest in science. It also spreads some science knowledge even if it isn't much. Popsci is bad because it gives people a sense of being more educated than they actually are(degrees do the same thing though). It also gives people a false sense that science works in grandiose movements. I think the pros definitely outweigh the cons though.
Those PHD students have spent years studying their field to get to where they are, and professors have spent even more. Exactly how long do you think it's going to take you to reach this level in EVERY field?
What if matter can not enter black holes but only orbit it due to gravitational spin. Think of it like the international space station falling but never falls due to the earths spin thus orbit.
Black holes are gravity held together by gravity it does not use matter or destroy matter It only makes and smashes elements by crushing presser within its accretion disk and after it dies its accretion disk forms new stars and planets due to the clumping effect of the spin but super massive black
>>8125246 :holes gravitational forces are too weak to keep stars and planets from forming within its disk thus black holes are just gravitational holes in space time that only recycle matter It does not destroy or touch matter its self. hawking is a quack. and black holes are fucking matter redistributors.
This seems autistic. Things do not orbit earth because of its spin. They orbit because of their horizontal velocity. The super massive black hole at the center of our galaxy for example does have complete solar systems orbiting it but nothing orbits at a super close distance like near the event horizon.
Obviously, to keep the topic "sexy", conditions that really fuck people up are of interest. But above all we are interested in extremely rare-yet-identifiable conditions, which might not even negatively impact a patient's life to a significant degree.
The type of thing for which there are fewer than 1,000 patients in the world at any given time.
In these hyper-rare cases, how can science and/or medicine be legitimately performed? You're dealing with a small sample size, which makes things harder.
In terms of rare conditions this has to be up there. Progeria, Epidermodysplasia Verruciformis, Cotards Delusion, Alstrom syndrome and Harlequin ichthyosis are to name just a few.
Joseph Merrick (OP pic) is a bit of a weird case since there is no consensus on what he suffered from, most likely Proteus syndrome and perhaps a form of neurofibromatosis: two very rare diseases in themselves, making him possibly the least lucky person in medical history.
How does this make any sense to anyone? I'm trying to find an explanation of this, but every single one, the author of the explanation clearly has no idea what he is doing. Not only that, but there's three different variants with no explicable difference in usage, yet every single one is different from each other.
>>8124736 >How does this make any sense to anyone? It barely does. It is an attempt to simplify the complex relationship between moving charge (current), magnetic field and force. All three are vectors in 3D space with an orthogonal relationship. Hence the left-hand / right-hand motor /generator rules. It's all about a magnet and conductor, move them and a current is produced, run a current thru the conductor and motion is produced. then you get people like Comment too long.

The equation for (the magnetic component of) the Lorentz force (F=q(B×v)=B×I), or the mnemonic using fingers?
The Lorentz force doesn't "make sense". It's just how the universe happens to be. Physics isn't math; you can't derive it from first principles, you just have to make empirical observations and describe the results.
One of those results is that the force on a charged... Comment too long. Click here to view the full text.
/sci/, I want to learn about concrete and cement, especially geopolymers. Not engineering stuff -- i.e., how to use it -- but more underlying basic physics and chemistry of it. Can anyone recommend a book or a review article?
I want to program science stuff but I also like messing around with making cool OpenGL shit. I know python but it gets really slow as soon as you run anything a bit complex. What's the best language for my needs? C, Lisp, Matlab?
>>8124264 would terraforming the moon be possible if we surrounded it with massive superconducting rings to make a magnetic field strong enough that we could sustain an atmosphere? I saw a paper about doing it for earth and they said something like the power from 12 nuclear power stations could easily produce a magnetic field something like 10% the strength of the earth's (i cant find the paper now but anyone else who has read it please correct me if im wrong) and it got me thinking about the moon.
>>8124198 Mathematical contests are more about how well you can apply trivial knowledge in convoluted ways - it has nothing to do with how good of a mathematician you are. That said, you should definitely feel good if you do well in them, but if you don't do well, you shouldn't feel bad either because it says nothing about how good you are at maths.
