Say I took a small muscle sample from my own body and grew it like pic related. Scientifically speaking, could it then be reattached to the body, either in its original place or at another site? Not muscleposter btw but I too cannot build it.

Sonoluminescence:
www.pas.rochester.edu/~advlab/11-Sonolum/sono1.pdf


The History: Sonoluminescence (SL) was discovered accidentally in 1934 by two German scientists
at the University of Cologne as a result on their experiments with sonar. They placed an ultrasonic
transducer into a drum filled with photo developing fluid in hopes of speeding up the developing
process. The fluid was full of thousands of tiny, short-lived bubbles. Once the pictures were
developed, they noticed small dots on the pictures. They realized that the bubbles in the fluid were
emitting light when the acoustic field from the transducer was turned on. Due to the complexity of
their setup, the effect was not properly investigated

The Process: Sonoluminescence is the conversion of sound energy into light energy. Sound waves
are aimed at an air bubble trapped in a flask. The sound waves cause the bubble to oscillate furiously:
(a) the bubble starts out at a size around 5 microns (millionths of a meter); (b) then it expands to a
maximum size (not to scale) of about 50 microns. At this large size there is a near-vacuum inside the
bubble because of the relatively few air molecules present. This low-pressure near-vacuum region is
surrounded outside the bubble by a much higher-pressure region, which causes (c) a catastrophic
collapse of the bubble to between 0.1 and 1 microns. During this compression phase a flash of light (d)
emerges from the bubble [2]. The conversion of low energy density sound waves into light requires a
concentration of energy by a factor of 1 trillion!!

What are some scientific ways that we could reduce wind and water damage during hurricanes and tornadoes.... and more importantly how can we reduce flooding in order to save lives?

I read that the most deaths that occur in a hurricane are due to drowning in massive floods from hurricane waters.

Would it be possible to place gigantic heaters beneath every street and when it starts monsooning or whatever and raining really hard the heaters activate so that the streets become super hot and the water evaporates immediately upon contact with the street?

Of course there will be alarms telling everyone to get into their houses so the streets don't burn them, but if we had boiling hot streets during hurricanes could that end flooding and thus drowning?

Boiling the flood water is literally fueling the cyclone while it’ll continue dumping down more water down, and will continue destroying property with intense wind. The only thing that will break is what you’re using to boil the water, along with the surrounding area.

Please explain two things to a brainlet.

2 - Can the accelerating expansion of the universe be somehow harnessed to make a machine perform work? If not, why not?

No. You need an energy differencial in the vacuum. Otherwise is like attempting to burn the ashes. Closest thing is the casimir effect.

2 -Likely not. It works by making more space. Maybe if you had an infinitelly long cable...but probably not. Also vacuum energy and dark energy are probably the same thing.

3 - if vacuum enery and dark energy are the same thing, then there isnt really much of it.

Of course only retards think having low iq means you will never accomplish anything and having high iq means you will be new Einstein. However you can't deny that iq does determine how easy it is for you to learn new things and how good are you at abstract thinking.

Absolutely right. In any case, I think that it is not only the successful completion of the Bachelor's and Master's programmes that counts, but also the social contacts and connections. And the more of these you have, the better you can fight your way through with a bad IQ or (quite casually put) even cheat through it. The woman who was part of the team developing the photo of the black hole (but didn't really contribute anything herself) is a very good and fitting example, anon.

If you bothered to read your article you would see that they detected faint brain waves. That’s brain activity, and the four physicians gave a faulty diagnosis.

>>10588906
I actually read through this list before making my post.

It’s been written by someone who doesn’t understand what brain death is, which is easily seen by him referring to someone as being in a coma and wouldn’t recover as brain dead, and the same for someone in a vegitative state. Most are of people who were in comas and pronounced they wouldn’t recover (still had brain activity but it was predicted they wouldn’t recover back to consciousness). For the few that were actually a brain death diagnosis, the coma was misdiagnosed as brain death (brain activity was not detected but was still present, just weak enough to not be detected without further investigation by a neurologist).
The only one that stands out is the 2008 Virginia women, though I am pretty confident further, more rigorous testing by a neurologist would have found weak activity, similar to the case >>10588903 brings up.

Again, brain death is only diagnosed when there is no brain activity. Weak brain activity in deep comas and vegitative states do not constitute brain death, even when enough time has passed that it’s safe to say that the patient won’t recover.

Doctors aren’t infallible, and these decisions are probably rushed through faster than they should be so that organ donations can be made while they have the greatest chance of success.

>>tfw said not to care about school, focus on getting pussy, and enjoying teen years
ridiculous nonsense.
future-proofing yourself and family and your future family is mostly what youshould be doing.
also: has anyone ever actually enjoyed their teenage years?

What do we understand thus far about how consciousness emerges? I'm a layperson. But as far as i know, it emerges on behalf of neurons, hormones, and neurotransmitters. Has anything been pinpointed it terms of "what" reacts with "what" to produce such and such pattern of thought? I guess i kinda understand dopamine and other neurotransmitters. I'm dumbfounded as to how words and pictures emerge inside our mind though. Perception of the past and future. The ability to put together an idea or ideas of whatever and grow an understanding of anything.

let the shit flinging commence. or please just contribute. i like thinking about this but my worthless fucking ape brain can only process so much outside of neurotic narcissistic obsessive compulsive self indulgence fuck me

God fucking damn /b/ro. That's some real serious fucking perspective your dropping like fucking BOMBS OVER BAGHDAD.

Do these Nobel prize tier scientists actually believe their own shit or are they just so hungry for glory that they don't give a fuck about being wrong?

No, we can't even agree on the concept of anything being emergent in the first place. The only promising leads for understanding a system that can generate variables on the fly to understand not just itself, but the world around it is in paradox modeling. That is, modeling it as if our minds can make up any bullshit that sounds logical (or illogical) and running with that assumption regardless of where it goes.


You are now exercising manual awareness of the fact that you don't know why people values things that make sense.

Can't tell if you trying to meme, but I was referring to people like Roger Penrose, Roger Sperry. Idk what got them to their ideas, everyone has some bad ideas, and these stuff are too much into unknowns, that's probably why.

im content for the most part. i just get overwhelmed by forces i dont understand that drive me fucking crazy trying to come up with an explanation of what the fuck i am or why i am etc etc.

> there's nothing makes it "simple" and there is no reason to think the right explanation would be "simple" (QM for example).

i have a feeling (lol a feeling DO YOU FUCKING SEE HOW FUCKING STUPID I AM AAAAAAAAAAAAHHHHHHHHHHHHH) that the answers are simple, just getting to them is complicated. Or maybe not even complicated, just difficult. Briane Greene explained some things very well for a literal retard like me to understand in some TED talks about string theory as well as how there could be physical evidence in terms of detecting vast amounts of heat in parts of the universe that may indicate a potential collision with another universe thus validating the multi-verse theory.
