Why does it feel so good to be drunk? Not why alcohol triggers whatever chemicals in our brain, but why did we evolve to respond with pleasure to substances like alcohol and drugs?
>>
>>7720478
because life is suffering and substance-abuse is the easiest path for temporary relief. also, alcohol is a drug, faggot, in fact one of the most deadly drugs.
>>
You have to talk about brain chemistry when you talk about WHY these things are good.

But it all boils down to evolution. We evolved with the pleasure centers in our brain in order to be spurred into action, in one form or another. We search for food and fuckbuddies, and either one of those activates a gland which rewards us with feelings of pleasure.

The strange part is this wacky coincidence that these specific chemicals which make us feel good don't just come from the gland; they also come from other sources opiates for example.

The relationship...

But why?
>>
>>7720238
There should really be a list of what is and what isn't a meme degree now.
>>
>>7720244
The official list of meme degrees, as judged by all /sci/ posters:

>Non-meme degrees: my degree (if I am happy with my job), my friend's degrees
>Meme degrees: your degree, all other degrees, my degree (if I'm not happy with my job)

If you and I got the same degree, yours is a meme degree because you went to a meme university, or at least specialized in a meme subfield.

Hey /sci/ 1st year 1st semester engineering major here looking for some help.

since i was such a fuckhead in hs and dgaf about class, they put me in remedial courses and now i have to make up all that time within this upcoming winter break. I essentially have to learn precalculus in a month. What other than pic related (my textbook) and khanacademy should i use?

Seriously, this board is wasted potential. Why can't there be a AI general discussing computer vision, machine learning, artificial neural networks, game theory, etc. instead of literally only shit threads and meme threads? Front page right now features threads such as "why are women dumb whores", "what is a good haircut that is chill and also academic", and meta threads about degrees.

Anyone into AI? What are you working on? Are you on ResearchGate? Any papers/books/MOOCs/resource that you found amazing?
>>
>>7720002
Because that'd be computer science, and everyone here is a physical science person. Machine learning is related only in a tangential sense, since it's applied math.

Also, within forty seconds it'd turn in to "arguing about conscious AI" and armchair-machine-superintelligence general, instead of actually discussing real mundane machine learning techniques.
>>
>>7720002
fuck the AI btw

>>7720002
because that requires people to do math.

>The sort that would be unethical if performed on people?

I'm thinking social sciences. Thousands of AIs in a double blind randomized controlled experiment. On one side, you have a control society, and on the other side you have an experimental society, where you change some policy like taxes or a regulation to look at its effects. Time would be accelerated and we will be able to see its effects in 5, 10, or 20 years.

Then they would be reset.

So my Ochem final is in three hours, and I don't know jack shit. Though, I've already taken my differential geometry and analysis finals, and I aced, and I'm good at physics, so this should be very easy, in comparison. It's chem, for christ's sake

Anyone got any pointers/tips? I need to learn Stereochemistry, Nomenclature of alkanes, alkenes, alkynes, Sn1, Sn2, E1, E2, Addition in alkenes, addition in alkynes, and their respective regiochemistry or whatever it's called. Also, conjugated pi bond mechs, and redox mechs. Finally, NMR, GC/MS,...

How does Lambda-calculus relate to mathematical logic and set theory?

The typed lambda calculus with $\to, \times, +$ and bottom type is the proof theory of intuitionistic logic, and the Church encoding is a model for the Nats (like the Von Neumann naturals)
All those terms have their own Wikipedia article.

traditionally, through the curry howard correspondence.

I think the more intuitive one is the curry howard lambek taken not just over CCCs, but rather over topoi (at least I usually imagine semantics are possible because there is a "truth object" - some "table" of truth values G such that maps A->G correspond to subobjects of A).

I believe that adding this puts a few more restrictions on the logic and calculus (martin lof?) But I really don't care that much because I never run into expressiveness issues.

But yeah, basically, curry howard lambek says exponentiating in a cartesian closed category is lambda abstraction is a function symbol etc.
>>
>>7719922
after googling, I'm wrong. The jump to the traditional topos semantics is non trivial. However, the CHL and exponentiation example are true.
