Every time someone talks to my son he traces their words into the couch he'd be sitting on, his pants, etc. What could this mean?
>>8198952
How old is your son? What level of cognitive abilities does he possess?
>>8198952
That is literally autism
>>8198960
He's 7
is consciousness ultimately separate from and independent of the brain or is just an inherent byproduct of the amalgamation of our most common thought patterns?
>>8198894
Consciousness is a quantum mechanical phenomenon.

It's just a manifestation of your physical neurology, there's nothing to else to it.

Philosophy of mind thread.
Eliminative materialism is the only thing that makes sense and psychology in general must adapt this principle. Your thoughts?

Philosophy of mind = philosophy of science with focus on psychology. I dont think /his/ is the appropriate place to go when discussing science.
I saw a report on mangroves on about how over 10,000 hectares of mangroves have died in Australia, and no one is paying attention to it since they are visually appealing. They seem to fairly important to the environment however, and I just wanted to know exactly why?
Also, there has been no set reason as to why they have all died apart from lack of water however I'd like to know about some other factors. So, my questions are; What are mangroves and what are their adaptations to deal with factors such as salinity, substrate, oxygen availability and wind?
Thanks!
Pneumatophore's are an adaptation to low oxygen.
IIRC magrove habitats store more carbon per hectare than regular forests, and provide a nursery for the juveniles of many species of commercially important fish species.
>>8198838
Mangroves seem pretty neat.

Also, Grey mangrove (Avicennia marina) excrete salt on the underside of their leaves.
Lick the leaf and you can taste it.
Is this map legit? I mean IQ lower than 70 would mean you have some form of developmental disability in the first world, but there are actually countries where half of population has even lower scores than that? How would they be able to run a functioning country if this was for real?
low IQ = slower development
pretty simple concept
Its probably from Lynn
Look into him at wiki and his "IQ and wealth of nations".
He does shitty approximations.
In one country in Africa for example his only basis for the IQ is a shitty cultural IQ test on 14 year olds.
Although there are real differences in IQ between nations, but the most effect has malnutrition.
For example a deficit in iodine and a change of the iodine diet after that let to an increase of 15 IQ points from 85 up to 100
>>8198727
This is purely conjecture, opinion and anecdote, but you can train yourself for IQ tests.
Schooling system may actually develop your thinking in a way that increases your IQ. That would pretty much also explain why many East-Asian countries seem to perform better than western countries.
I see it as a case of chicken and egg. Does a non-functioning country create people with lower intelligence, and do smart people want to stick around anon-functioning country, when they can leave and make use of their...

You are doing something meaningful and you have a future. Fuck off with your whining.

I understand, it's great, it's great - but there's a lot of shit I want to buy for myself (Vive compatible PC + Vive so I can do my own development w. unity) and I physically cannot buy SHIT because I get paid rent+food essentially.

You're doing robotics in SV and you want to jump on the meme development wave with a $2000 pc and $600 meme-o-vision with memewands? Don't be an early adopter, anon. VR will be MUCH better in two years, when you have income.
Can anyone link a video of anything that has gone high enough to film the curvature of the earth that does NOT use a fisheye lens??
>>8198595
If you do not trust the images by any of the numerous space and aeronautics agencies, I don't know what to say to you.
You seem to assume it's all false rather than actually approaching this with an open and curious mind, in which case, what's the point in responding?
here ya go
Ok, I agree flat earth is some bunk.
But Hollow Earth? Was Admiral Byrd a kook?
They would have figured out the earth was hollow a long time ago through the behavior of seismic waves from earthquakes. The Earth does not behave like a hollow object.
>>8198591
How would you explain the earth's magnetic field? Also, we know the mass and average radius of the Earth and thus the average density. This density is much higher than the density of the crust (which we can measure directly), thus there's more dense stuff underneath. Also volcanic activity.
It would take quite a lot of patchwork to explain a hollow earth. The fun part is that Gauss's law tells us that a hollow earth will behave exactly as a solid earth in terms of gravity and orbit (if they have...

Milk in the US is laden with hormones and whatever else garbage. How can anybody do proper studies when it's almost impossible to purchase milk in the US that hasn't been tempered with?
I grew up on the outskirts of a city and drank mostly fresh, raw goat milk since we owned a goat. I never had any diseases or parasites growing up. Moving to US I was shocked to find out what people actually called milk.
I can't say much about milk's effect on bones but I can say that drinking milk in the US is a bad idea.
There's several studies...

Hey /sci/, I am extremely interested in learning electronics. Are there any really good and insightful books, YouTube videos, ect. for beginners?
google.com
>>8198424
Google led me here
What kind of electronics do you want to learn? If you are interested in pic related, you should read the relevant chapter in Griffiths' book: Electrodynamics. That'll give a fundamental understanding. If you are interested in practical electronics, don't bother. Hall has a good book, but you may not have the will to read through that thing (it's the best book you'll find, but that doesn't mean I think it is any good). I would advise getting some equipment for tinkering. Learning the theory behind circuits is great, but actually building them afterward...

Do i know chinese or not?
Useless word games. There are no insights to be gained in thought experiments like this, save about the limitations of our language(s). And most do not even make it that far.
Well its not completely useless. It gives us an insight of how especially the field of psychology and how the avarge man looks at a why humans do why they do. The dualistic split between a) he is speaking chinese, and b) but he does not understand it.
The understanding part part is so broad and nearly not measurble at all.

what is the evolutionary advantage of not listening to music

>>8196812
There isn't an inherent advantage.
Our enjoyment of music is, however, a consequence of our brains ability to detect patterns, which is evolutionarily advantageous.
I have my first official day tomorrow as a PhD student. I am starting by doing a lab rotation in a summer internship.
anyone who has done this, what can i expect from my first day? first month? first year? from the experience in general?
This is your last chance to get good sleep for the next several years and you're going to blow it taking questions from memesters? Go to bed idiot.
>>8196639
you're scaring me
>>8196643
Be scared. You picked the hardest class to play as in this shit videogame no one even beta tested.
Get some sleep. Remove 4chan and any other deconstructive webforums from your bookmarks. Now is the time to grind for XP.

Do you fear automatization?
>>8195880
Its just a continuation of the mechanization that's been happening for hundreds of years.
automation/"robots taking jobs" is literally the best thing that can happen to humanity
the sooner all these trivial tasks are automated the better
all progress is caused by increasing worker productivity
aka
automation
