Woo else has been up since 3 am? Cus I know I have.

I need sleep

Okay now

What is consciousness?

Like yeah we know that we are alive because we are breathing, we bleed, we're talking, we interact with others. But then, how exactly do we know that for a fact we are conscious? How do we classify something as "conscious". But, if we were able to classify consciousness and even identify it and what makes it up, would we be able to transfer consciousness? Like transferring it to a machine, other people, or even into a computer program that has the consciousness of others in it as well.

If we were able to do so, then, hypothetically, we could transfer our consciousness to a machine/computer that could allow us to "live" forever. But would that be ethically/morally correct?

But say that we did so happen to transfer put consciousness to a machine, right? It acts as if it's human and it will believe that it's human. So, simply put, it'd be a continuation/expansion of our current life, just simply in another form (possibly while we're still "alive").
But say that you cut off the power to this conjured up machine. Wouldn't it count as murder? After all, you did just take away the life/consciousness of something that could be considered a sentient being, as it believed it was alive.

Something doesn't need to have ANY organic matter to be considered alive.

Is this possible? If so, how soon? Is it proper? Should we attempt to do this?

If you truly want to understand the answer, you'll have to know everything about quantum mechanics.

It's completely possible. 'Organic matter' is just the stuff primordial life found fit to create itself from and ultimately similar systems could be made from other elements.

A organic brain compared to a synthetic, non-organic brain may have some differences in design and it may be hard to counteract some things such as response times of electrical signals if we have to upscale certain systems in the brain but overall I don't see why we couldn't.

There's no reason to attempt it for at least a century or two from now and it's very hard to speculate how humanity will have developed by then.

Surely this topic is currently being researched and looked into at this very moment.
The other question is: how do we know we're conscious? Yeah we're aware of what happens around us, but how do we know that we truly are conscious? What animals fall under the category of being conscious? If so, what are the requirements?

Well, i guess i could let it pass as earth means "dirt" or "the ground" in latin.

I like the idea

I am getting real tired of planets being named "X5340-343" kind of shit. Sure, keep it that way in the scientific catalogs for database purposes, but giving a planet a good name is important, and I think we lost that spirit of the whole thing along the way somewhere.

>>7694118
I think it's good to give boring names to boring planets

So far we have confirmed the existence of over 2000 exoplanets, most of which consist of gas giants with no particular characteristic. In the next few years (basically with TESS and its successors) we'll start to find small and rocky planets which may possibly be similar to earth. At that point we'll start giving them cool names, also because the general public will become interested etc

>"Ecstasy will put holes in your brain" is just a myth

http://www.ncbi.nlm.nih.gov/pubmed/24560859

research is emerging that these Amphetamine drugs are neurotoxic even with the typical dosages used.

We all know that brain damage is permanent and never gets any better, so its quite significant that the research continues to reveal the risks of these drug uses.

Think twice before you decide to roll, since any user has suffered irreversible brain damage it seems.

http://onlinelibrary.wiley.com/doi/10.1002/hup.2390/abstract

MDMA is certainly damaging after 25years of empirical research: a reply and refutation of Doblin et al. (2014)

Andrew C. Parrott is a renowned scientist in these matters and this is a fully-published paper demonstrating the neurotoxicity of these compounds.

It is quite scary to imagine that one small dose of amphetamines can land you with irreversible cognitive deficits. It would be wise to keep this in mind even with more common amphetamine drugs such as Adderall.

Dude seriously i'm fucking scared now after reading this paper, it says even the normal dose habits for addicts produce neurotxicity, and like

i've used adderall on lots of tests before after /sci/ told me of its use in hardcore studying.

It says that cognitive function usually improves after stopping amphetamines use but does that mean recovers to normal completely? am I fucked...

Ok /sci/, I'm a retard and I accept it. However I have a question for all of you non-retarted people: does energy truly exist? Is it actually something that truly is, or is it just a representation of systems capability to work? Can energy be an actual substance and exist without the system, or is it just a property of the system?

Q: Why does water evaporate?

If you leave a glass of water in a room at room temperature forever it will not boil, so it is not turning to vapor, what happened to the water?

Drunk Theorem #1: Composite numbers exist and there are infinitely many.

Assume that there are no composite numbers. In other words, no numbers that are made by multiplying primes with each other. These numbers, which are not primes, are therefore only made by combinations of each other.

Counter example: 4. Which is (2)(2). So we know that there are composite numbers.

So lets now assume that these composite numbers exist but there are only a finite number of them (maybe only 4).
That means we can list them as
4,6,.., N
With N being the largest composite number. But we can form a number by multiplying
4*6*...*N and if we replace these composite numbers with their prime factors as:
4*6 = 2*2*2*3
we have a multiplication of primes that form a new composite number that is not in the list.

So we add this new composite number to the list but then we can do the same operation infinitely many times. Therefore, there are infinitely many composite numbers.

QED

That is almost exactly how I worded that on my mind back when I was originally thinking of it. Is there are mathematics professor at Standford who'd like to rate my drunk proof skill?

Anyways, does anyone have similar stories? Maybe another drunk theorem? Maybe an EE guy thinking about circuits that don't make sense or whatever?
Just share it, I know you faggots get drunk too.

>Once I got drunk and decided I could get laid easier by tricking girls with my scientific knowledge of the vagina.
>And it worked.

Drunk Theorem: Knowledge is sexy.

By tricking girls into thinking I know exactly what way to tickle their clit and I can make them orgasm in minutes, I can get them back to my place in no time.

Counter example: getting slapped. Hard.

But let's say you're at the bar. Dressed nice.
>walk up to inebriated 8/10 grill
>hey my name is blank, I bet I can make you orgasm in minutes
>swiftly get slapped across the cheek
Probably setting the bar too high for an example but hey.
>walk up to inebriated 6/10 this time
>bet I can ask you one thing and you'll immediately want to sleep with me
>plz no slap
>"uhh, lol okay I'll bite"
First test subject.

This girl was in college I'm assuming.
I offered to take her to a nice restaurant and get her a drink somewhere more confortable. We drove to this place down the road, walking distance really. I'm making casual conversation and she's asking what I plan to ask her that's so "orgasmic". I tell her she has to wait.

>arrive at this place, thankfully were wearing the right formal attire
>order our food and drinks
>the whole time I'm not even really flirting openly with her but I still have her interest.
>making more casual conversation. Abruptly and without warning I immediately say, in the middle of her speaking..
>"when's the last time you orgasmed in another man's bed from nothing but the tip of his penis"
>"how good was the orgasm itself? How long did it last?"
>immediately tosses back her drink

That shared folder has actually been around since the beginning of 2015 and some anon is working on it.
Taken from the notepad file:
"This is essentially a libgen mirror of recommended books
in the field of STEM and some social sciences. Nothing
is as in depth to fully warrant a complete undergraduate
education but enough to be competent in the subjects. For
the math section, it's more geared towards what an engineer
would be required to learn. I guess I'm ultimately inclined
towards the practical versus the theoretical. Despite that,
I want to bring together books which would help establish a
strong foundation for any STEM student in
the future. Quality instead of Quantity.

Poorly scanned texts are going to be processed through
ScanTailor and Adobe Acrobat (OCR). The really poor scans,
or those which lack contrast I will have to batch process
through GIMP, although the results have been rather...dis-
appointing. For the I the books which are passable, I
might eventually go through each book to put each bookmarks
(see Math/Courant), some time later. Then, they are final-
ly 'completed'. If I ever get around Adobe inDesign, I might
remake some entire thing (K&R's C)

For the best way to browse through onedrive, I recommend
the list view rather than the thumbnail view. (Press the
button right next to the Sort)
