we have it, its called modafinil, the stuff is magic, pretty much the only reason i got a first in my bachelors

>>8196207
when you come off of it, you are worse than before

read more about it online, its a placebo at best.

what the fuck are you talking about?

Yes.

hhhow?

Alright, I'm just gonna tell you a very simple one. Look up a university. I don't know if all do it, but for most, their degree requirements are publicly available. Of course, some of the stuff on there is useless or ambiguous, but a lot of the core stuff is useful. Here's the UCDavis computer engineering requirements as an example. http://catalog.ucdavis.edu/programs/EEC/EECcourses.html Basically, what you do is look at a class, and look at the topics it covers. Now go to google and youtube, and look up videos of the topics. Bam. free education. Downsides? No proof you learned anything unless you do your own projects, and your knowledge will most likely be incomplete, or missing some topics.

I like him because the articles on black holes and stuffs at his websites are good.
On the other hand, fuck that face give me nightmare everytime

I asked someone reading one of Hawking's books her reason and that's the answer I got. Tbqh I think a lot of his readers are pseudo intellectuals

l need that the steepnest varies in function of a like pic related, the smallest a is the more step the function is and the bigger a is the less step the function is

That looks like an arctangent function compressed to a range of (0,1)

>>8193833
Yes.

If it was activated by X/Y chromosomes or some shit, then maybe.

>>8193833
No.

I always recommend james stewart, most of theorems are proven and take you to the next level, exercises have a varying level of difficulty too, for other subjects that involve calculus like numerical analysis i recommend dennis zill

Principles of Mathematical Analysis, Rudin and Linear Algebra Done Right, Axler.

>What will roads of the future be made of?

Asphalt. It is nearly 100% recyclable, durable, coarse, and dirt cheap. There is literally no reason to switch to something else as our primary material for roads.

>>8192731
except its not environmentally friendly

also I guess it depends on where you live, but where I have been, the streets are a horrible mess of bumpy, patched asphalt. Also asphalt streets need to be repaved more frequently than glass one would.

Bituminous asphalt is made using oil, which we are also trying to steer away from

Glass will never be used on roads. See the other guys post

>What can or should I expect now /sci/?
If anything. Is letting go of a natural tendency expected to have any observable (or internally sensable) consequences or are intents of this variety not causative to cognition in first place?

Come on /sci/. If you don't make a prediction you know someone else will, and you know that nine times out of ten it'll just end up being unfalsifiable platitudes. Any falsifiable hypothesis is better than no hypothesis at all.

Why is OP such a blogposting faggot?

Infinite, infinite, infinite, probably not.

>>8190677
Don't know, but likely finite.
Don't know, but near certainly finite.
Don't know, but with certainty, finite amount.
Very unlikely. The brain is a machine, and as it presently exists, it isn't likely capable of existing in a state of that sort. Terms like "100x as euphoric as" are also not very useful.

Every "chemical" is a combination of set values interacting with one another in specific ways yada yada the point is, on earth we have the elements of the periodic table. If you wanted an answer, you would need to know the maximum affordability for size of a molecule. Also, if you're including solutions, the number will increase exponentially.
To the second part, the brain has a very specific structure, so there are not infinite molecules that could do what you are suggesting if there is a maximum molecule size. There very well may be, though. Maybe even 420x.

Symbolic thinking for mathematics develops habitually.

Most people find it uninteresting and useless. Like if someone were to show you there spoon collection. That combined with the pretentious "being good at math means your smart" meme means they would rather not try, than try and fail.

because it's completely useless by itself and thus unlearnable without first knowing 'what it can do'

-Cow's milk is for calves not humans.
-Human breast milk is for infants and children under 5 years of age.

If you are an adult who consumes milk products, you are fucking stupid.

why is he writing your thesis? tell him you'll resize them and make some changes and do it quickly

OP here. He has also resized some other figures and I have not seen the damage on my results or conclusions section but I am worried that all my photomicrographs with scale bars are gonna look like "Fun-house" mirrors.

>>8192822
Have you discussed this with your advisor?

>>8195592
the mind is a powerful thing
since it controls so much shit, it can easily fuck your body intentionally and unfuck it depending on random shit

Maybe it causes epigenetic changes that somehow rewire the nerves that are sending pain signals when they shouldn't.
Placebo pretty much only works on stuff like back-pain, migraines and the like. Vague conditions without a clear cause involving abnormal pain. It doesn't actually work against stuff like infections and cancer.

More specificity is needed on what constitutes "human-level AI". I too would like to know more. Maybe Turing Test Complete?

>>8194542
Yes, though I think we'll have the first text-based human level AI much before then. Probably by 2018.

Visual processing is extremely difficult compared to linguistic reasoning.

If he can, you can with certainty say someone else will do it first if they haven't already.
