I am not sure if this is a correct place to ask but still. Here is the quote from a book:
Though we feel that we can choose what we do, our understanding of the molecular basis of biology shows that biological processes are governed by the laws of physics and chemistry and therefore are as determined as the orbits of the planets. Recent experiments in neuroscience support the view that it is our physical brain, following the known laws of science, that determines our actions, and not some agency that exists outside those laws. For example, a study of patients undergoing awake brain surgery found that by electrically stimulating the appropriate regions of the brain, one could create in the patient the desire to move the hand, arm, or foot, or to move the lips and talk. It is hard to imagine how free will can operate if our behavior is determined by physical law, so it seems that we are no more than biological machines and that free will is just an illusion
Is there any source for these experiments? I can't find anything.
I also remember watching a video on youtube that explained this experiment well, I guess it was a cut from "Through the wormhole" or some other popular TV show about science. I hope someone would recall it.
If you haven't found it, neither would i.
Read a book titled Connectome it's written by legit mit neuroscientist and he explains how a precise scan of our brain contains all our memories and personality.
The experiments you mentioned must be legit, stimulating brain is used often in science.

Thanks for the video.
This was given to 10 year olds.
Can you answer it?
>>8128664
the top is 44
I dont' know how to do the bottom unless that 2cm label is labeling the small vertical length. In which case the answer for the bottom one is also 44
>>8128664
First one is 44cm
Second one is also 44cm

What is /sci/'s opinion on Luboš Motl?
>highly talented theoretical physicist
>lost his job for political reasons
>became a professional shitposter
I honestly wouldn't be surprised if he posted on /sci/. In his blog he calls colleagues he disagrees with "imbeciles" and "crackpots".
>>8128527
Love his blog. I read it all the time. I don't always agree, but he's always entertaining. Yes, he knows his physics too.
I don't think he posts here much. He does a lot of work at the stackexchange and similar sites though.
>>8128527
>lost his job for political reasons
I thought he lost his job because he's utterly insufferable.
>>8128527
>lost his job for political reasons
ok, what happened?
I see Aaronson write

but it isn't well known to me, or presumably others outside of certain fields.
I suspect that asking for an unbiased rundown is asking for something that doesn't exist.
Google turns up a lot of posts by butthurt academics over the issue and I'm not willing to read all the shit available.
Give me a one paragraph rundown if you can.
What do you think it feels like to be the best in the world in your field?
>>8128492
Must feel depressing. Because high intelligence comes with higher levels of nihilism and apathy. You inevitably realize how meaningless and futile everything is.

Just because some study says intelligent people are more likely to be depressed that doesn't mean every intelligent person is depressed.
I bet you choose to believe this because you're depressed and you want this to mean you're smart
I was wondering. The human brain or any earth-brain really probably had a common ancestor. They're all evolved on the same framework; That is a neural network.
Would the brains (if they have such things) of an alien species that evolved on a different planet be likely to be similar? Is the idea of a centralised neural network the only solution to the problem of cognition and learning?
Are there other architectures that would provide vastly different results?
How so? What would an Alien brain or equivalent learning/control organ behave/function like?
it would probably be pretty similar
>>8128080
I believe its possible to simulate human neural networks on silicone for what it is worth.
If it has an input output system thats compatible with Real-Life.exe it can be made intelligent.

How come nothing intelligent ever came out of the millions of years reptiles and dinosaurs/birds had on this planet? Were we just incredibly lucky in the sense that everything just fell perfectly into place?
I'm not educated enough in this field (which is why I'm asking this question) so this might come off as incredibly stupid but was it because there wasn't enough variation in the global gene soup?
>>8127808
Because God just wanted one intelligent species on this planet and raptors were getting to uppity to leave around.
Probably a number of factors, including diet and basic anatomy. Birds can be pretty smart, just look up videos of corvids performing cognitive tests at the level of infants and chimps.

How close should a moving part be from another moving part be to be mostly frictionless and not grind or be too stuck?
In mm
.10th mm?
.05mm?
Do manufacturers even go to .05mm?
EXAMPLE-If this big circle you see is rotating how many micro mm should it be from its surrounding metal so it moves without friction catching it.
>>8127741
About 3.50
>>8127769
3.5mm?
Thats way too wide.

SpaceX is going to literally take over and monopolize all of space.
Good thread
p.s not really
Do they plan on being able to recover the second stage at some point? That seems like it's still a pretty big cost per launch.
>>8127663
Yes, but it might not happen until development of the methane raptor engine is completed.
>The broader Raptor concept "is a highly reusable methane staged-combustion engine that will power the next generation of SpaceX launch vehicles designed for the exploration and colonization of Mars". According to Elon Musk, this design will be able to achieve full reusability (all rocket stages) and, as a result, "a two order of magnitude reduction in the cost of spaceflight.

What are some interesting current biological studies?

>Scientists in the US are trying to grow human organs inside pigs.
>They have injected human stem cells into pig embryos to produce human-pig embryos known as chimeras.
>Walter Low, professor in the department of neurosurgery, University of Minnesota, said pigs were an ideal "biological incubator" for growing human organs, and could potentially be used to create not just a pancreas but hearts, livers, kidneys, lungs and corneas.
>if the iPS cells were taken from a patient needing a transplant then these could be injected in a pig embryo which had the key genes deleted for creating the required organ, such as the liver: "The organ would be an exact genetic copy of your liver but a much younger and healthier version and you would not need to take immunosuppressive drugs which carry side-effects."
>These embryos have been allowed to develop for up to 62 days - the normal gestation period is around 114 days.
>Like the team in California, Prof Low said they were monitoring the effects on the pig brain: "With every organ we will look at what's happening in the brain and if we find that it's too human like, then we won't let those foetuses be born".
>In Greek mythology, chimeras were fire-breathing monsters composed of several animals - part lion, goat and snake. The scientific teams believe human-pig chimeras should look and behave like normal pigs except that one organ will be composed of human cells.
But of course, atheist-hippies ruin everything
>But organisations campaigning for an end to factory farming are dismayed at the thought of organ farms.
>Peter Stevenson, from Compassion in World Farming, told me: "I'm nervous about opening up a new source of animal suffering. Let's first get many more people to donate organs. If there is still a shortage after that, we can consider using pigs, but on the basis that we eat less meat so that there is no overall increase in the number of pigs being used for human purposes."
>>8127548
Goddamed hippies ruining good science because the media told them to care about this case. I work regularly with hybrid human mouse cells called 1A3. To me this is no different. We have been using animals to test on for centuries and this is pretty tame compared to the shit the pharmaceutical industry puts monkeys through. medical progress requires living subjects and i rather it be an animal than a human
I think someone mentioned a guy trying to find a way to slow aging here before. Don't have any links, but it might be worth looking into.
