how is brian formed?
how machine get telgant

Derailing this shit thread:
Is the D-Wave actually a quantum computer?
If it is, is it fast enough to be useful?

>>7205180
No, it is not.

>>7205179
idk scientists need to find that out. then upload it to a computer. trillions of neurons can be simulated like a video game

That's not how it works you retard.

Fucking kill yourself singularity shit-eater.

Wait, what?

> reverse engineer the brain called 1, 1 will reverse engineer its brain to 2, and recursively keep making its brain better until infinity

That makes no fucking sense.

>>7205167
>Einstein's brain will be a babby 1 month year old brain compared to what will come

that's not even a relativistic metaphor if you know how deep this goes

luckily, no one has a clue how to do it, because it is paradigmetrically impossible.

you heard me, paradigmetrically.

>>7205647
I think that's in Fahrenheit.

>>7206076
I think it's pretty easy.
But since we also killed our predecessors our successor would also need to extinct us, and theirs them, and so on. Obviously few people are interested in creating such a beast, an pretty much everyone has a huge incentive to oppose it. So I don't think we will truly be surpassed, except perhaps by accident.

>>7206065
thats because you are probably a shit tier physics major that doesnt know about for loops or recursion

>A protein that may partly explain why human brains are larger than those of other animals

size of brain == intelligence

If we can upload a brain into a computer, the computer can make the brain larger and larger much like increasing the radius of a circle in a simple graphics program. The brain will be correlated with size, and with enough computational space can make the brain a trillion times larger, and thus a trillion times smarter

>>7206084
a brain on its own would not be able to kill you, m8

are you saying that blue whales are the smartest beings on the planet?

>>7206348
they have better language than we do

>>7206348
humans have pens and opposable to right shit down with. dolphins do not. if a brain was uploaded to a computer, it would have perfect memory and could load a lesson instead of having to learn the traditional way through school

You don't need to reverse engineer the brain to figure out how to improve cognition. It's just a systematic process of trial and error. Check out Quantified Mind.

First step is cutting out harmful addictions, such as drugs and porn/masturbation. I can guarantee that by cutting them out your mental state will already be far better. Eat healthy and take supplements for any deficiencies. Exercise regularly, daily cardio and/or lifting 3-4 times a week with a good routine. Get ~8 hours of sleep or however much you need to wake up feeling energetic the next morning, no more no less. Meditate daily (mindfulness / concentration on the breath). After you have sorted out physical factors, such as dopamine balance in the brain, it's a purely mental process which requires constant meditation. But likewise if your brain isn't ready for it, and you have deficiencies, you'll see very little progress. Keep working on yourself constantly.

Hopefully when the scientists do make such a feat of AI, they will put in effect serotonin production in the gut so that brain 2 does not question its existence in a cynical fashion and exterminate itself.

if you analyze what the people with the highest intellectual achievements spent their time doing, it was generally working and meditating/lifting/whatever else

>>7208817
if you analyze what the people with the highest intellectual achievements spent their time doing, it was generally working not and meditating/lifting/quantifying their minds

>>7208845
Intellectual achievements =/= high intellect. Anyone can be successful if they work hard.

This stuff really doesn't take long. Think of it as mental hygiene. To focus effectively, you need to clear your mind of disturbances and keep it in balance. 20-30 minutes of meditation a day won't take up all of your time, neither will a healthy amount of exercise.

>>7208151
>Turn 1 lobe off so it could sleep
>1 lobe functional
>1 lobe smaller than the human brain

>>7208866
20 minutes "quantifying" your mind
30 minutes of meditation a day
5 minutes before and after getting ready
30 minutes cardio a day 4x per week
15 minutes shower, change clothes, etc after add another half hour for travel if you do this at the gym
90 minutes lifting 3x per week, with 15 minute drive to gym, 15 minute drive back, 30 minute showering/eating etc after

and realistically if you have a full-time job you only have 3-5 hours of free time per day during the work week that's not spent on things like eating or brushing your teeth, especially if you're spending 9 hours in bed (generally what you need to actually sleep 8 hours)

>>7208845
There's a difference between geniuses and normal successful professionals.

No genius would ever find himself in a state where he needs to ask an anonymous algerian mimeograph board about reverse engineering the brain.

So clearly, OP is not a genius and so trying to copy the habits of geniuses will not work out for him. However, if he makes an effort to stop being a retard he still might be able to contribute to science, and doing the kind of thing that non-genius successful normalfags do will help.

>>7208894
I don't mean to be a dick, but if you seriously find yourself in a situation where you do not have a couple hours of free time a day you should seriously reevaluate your career path. If you are interested enough in your field to spend that much time working great but if you can't even handle it and take care of yourself you should consider something less difficult and more manageable at your level of skill and intelligence.

>>7208905
Agreed.

>>7208905
what are priorities

>>7208937
Exactly man. Get them fucking straight. It's unhealthy to do otherwise.

>>7208894
9 hours is too much for a fully grown adult.

>>7208894
>30 minutes of meditation a day

lmao

>>7208942
Lol at this fucking propagandist who wants people to spend upwards of 60% of their free time meditating, "quantifying" their minds, and lifting
Enjoy undergrad while it lasts bro

>>7208943
That's wrong, actually. 7-9 hours is ideal.

But you are missing his point. Unless you are highly abnormal it is going to probably take you some time to fall asleep at night, and it takes some time to wake up too. If you're giving yourself chronic sleep deprivation only sleeping 6 hours a night or something, you might pass out instantly but if you're getting a healthy amount of sleep it does take 20-30 minutes to fall asleep at night, so 8 hours in bed wouldn't be quite sufficient for 8 hours of sleep.

>>7205167

>D wave

>>7208949
>upwards of 60% of their free time
Uh, what?

You're the one who's apparently so autistically obsessed with your studies you don't have literally 90 minutes a day to take care of your body...and yet you still have plenty of time to post on 4chan.

I'd tell you to 'enjoy' living your fucked up workaholic life but sadly I don't think you can.

>>7208959
>don't have literally 90 minutes a day to take care of your body

meditation literally does nothing for your body, are you retarded?

>>7206348
Its dependent on brain size to the proportion of the body, we have extremely large/heavy brains in comparison to our bodies. You will notice a chimp, would have a much much smaller brain then the human but it might be more proportionate or even smaller then in comparison to there mass size.

>>7208972
>stress has literally no effect on your body
Wow glad you've discovered this, modern medicine is going to be excited to learn the news!

>>7208972
Really, it does nothing? There are plenty of studies that show it improves focus, reduces anxiety, stress and depression, improves creativity (by reducing "cognitive rigidity") and more.

It has been shown to increase grey matter in the brain, and also cause structural changes in the anterior singulate cortex, the part responsible for monitoring focus and self control, after just 11 hours.

There is much, much more I could mention, but I won't spoon feed you like a baby, because google exists for a reason and if you are interested it's all on the internet.

>>7208985
Still not true. Inuits have the largest average brain of modern humans but score low on IQ tests. Neanderthals had significantly larger brains than Homo Sapiens but did not have nearly as advanced cultural practices. The brain isn't just for intelligence.

>>7208155
Dolphin brain transplanted into a braindead human body fucking when?

>>7209033
Nope it's true, IQ are just tests, in fact if you take it every two years they lower your IQ points by 5. Inuits development is based on there circumstances. Neanderthals are actually smarter then homosapiens and the reason why Asian and Europeans have larger brains as we interbreed with them, test indicate most european carry 2% of their dna which is enough for genetic carry over.

It's not a computer, but it's fast for resolving a kind of problems.

Yes, I already know you're illiterate.

>Most of the work on Neanderthal and fossil AMH brains has relied on endocasts and the internal morphology of the cranium. However, this approach is limited to investigating external surface features and the overall shape and size of the brain, and provides no information about internal brain organization. For instance, identification of the lunate sulcus on endocast surfaces is highly ambiguous, making the size of the primary visual area (V1) difficult to measure from endocasts. An alternative approach has been to use known relationships between overall brain volume and the volume of specific brain areas in extant primates to estimate the respective brain region volumes in fossil crania [7]. While this approach is broadly reliable, it does assume that identical overall brain volumes imply identical brain organization. Although there are conserved patterns of scaling in brain organization across mammals [7,8], this is not always the case: the size of the visual system, for example, varies independently of the size of other sensory systems [9,10]. More importantly, there are well-known examples among primates where mosaic brain evolution has resulted in brain regions that are significantly smaller or larger than would be predicted by overall brain size alone. Among the great apes, for instance, gorillas and orang-utans have unusually large cerebella and relatively small neocortices [11]. Assuming that similar endocranial volumes equate with identical organization within the brain may be seriously misleading.

Give an actual source, get fucking press releases in return.
