I'm on the fence between saying it's impressive you're so knowledgeable, to saying you wasted a ton of time and don't know anything. Like jurisprudence. What the fuck is that? Did you google "list of science subjects," find jurisprudence, and then spend hours reading about all the scientist in that field?

What field would I need to study to try and learn and understand about human consciousness? I want to understand everything about the human brain and how it reacts to outside stimuli via the invironment, as well as how genetics play a role in how the person is set from birth to be like and their "mental ceiling" for creativity, intelligence, etc. I also want to know how the brain interprets sensations that are channeled to it via touch, taste, smell, etc, etc. Thanks in advance for the help

Can any Medfags help me out?

Almost all the info around on this topic is openly hostile and all articles is "how to identify and get rid of Psychopaths".

Is there anything at all FOR psychopaths?
How are they supposed to deal and get through the life? What are the ways and tactics of productively dealing with society other than exploiting everyone until they figure out and tell you to fuck off?
Is there a possible way to maintain productive long term relationships with people?

no because they're usually criminals and assholes

>How are they supposed to deal and get through the life?
Learn emotions.

Society is shit deserves nothing other than exploitation. What do you mean by productive?

>Is there a possible way to maintain productive long term relationships with people?
Learn emotions and take a liking to people. Find people that are so complex that you take multiple decades to figure them out. This will result in you keeping them around longer
>>
>>8798806

The fact that "psychopaths" have almost no activity in their PFC or temporal lobes make a good argument for morality, what "psychopaths" are famous for lacking, simply being foresight with cost/benefit analysis. The more intelligent you are the more consequences of an action you can perceive the more efficient you are at choosing paths which avoid the most painful consequences. Psychopaths can't do this thus they always choose inefficient paths and suffer the worst consequences.

>it's anecdotal evidence
Fuck you I'm posting it anyway

I used to smoke weed. While high off my ass, I consumed about 3 years of topology lectures in about 4 months. I could do all the exercises. I took an IQ test, got 154.

About 6 months ago my weed dealer went to jail and I've been sober ever since. I have difficulty concentrating in class now (never had that problem before). I can't watch lectures on youtube for hours anymore. I can still retain information if I try really, really hard. I took an IQ test last week when that faggot posted a thread on here. Coincidentally, it was the same site I took the test on before. I got 130.

I can't tell you if weed made me smarter, because I'd never been tested before I scored 154. I can't tell you if smoking weed will get me my 24 points back. I can't tell you if it was a fluke, either.

But don't smoke the ganja, bro. There's a nonzero chance that when you stop smoking it you're going to be cognitively impaired, or at the very least, lose your passion for learning. Err on the side of caution.

So, based on this text I took from Lehninger's Biochem. I don't get why the CAC intermediates would be drawn off to gluconeogensis, in a diabetes melitus condition, if the person had just ate a bucketload of sugar! Why would the body try to synthesize more glucose if the extrahepatic are not even consuming the blood glucose?

Hello /sci/, i'm an average guy with slightly above average knowledge in science and i'm completely baffled by the double pendulum.

How come the movement is random? If we had two completely identical closed systems with two completely identical double pendulums in each of them, wouldn't the resulting motion be identical? When i'm saying identical, i mean fucking identical - exactly the same molecular structure on both pendulums, same starting positions, same pressure and temperature in the closed system, exact same amount of air e.t.c.

Why is the produced movement still random? Can anybody explain this to me?

If they are both identical. the resulting motion will be the same.

The problem is kinda like the chaos theory, there is so many variables to consider that it's almost right to say it's random.

>>8810477
Do you have to consider the acceleration of the red pendulum when determining the location (relative to the tip of the red pendulum) of the blue pendulum

t. brainlet
>>
>>8810482
There are only two variables, though. What makes a system chaotic isn't the number of variables, but the sensitivity to those variables and their initial conditions. A tiny, tiny change is either starting angle results in a dramatic change in the trajectory, which is the definition of chaos.

If this is true, you might actually be autistic. Do you really enjoy rote practice more than pushing the boundaries of your knowledge? Try expanding your horizons a bit: try to come up with a problem in number theory that others haven't thought about, and then attempt to solve that.

Or, even better, spend some time trying to solve problems that we know about but don't already know how to solve. You could give the Collatz conjecture a go, for instance.

>try to come up with a problem in number theory that others haven't thought about

Chill the fuck out, I have 2 more years before I have to write a thesis. Coming up with a babby problem today that some russian probably thought about 150 years ago is pointless. Time is better used rising to the highest level.

>Do you really enjoy rote practice more than pushing the boundaries of your knowledge?
There is no nothing rote about writing proofs.

>spend some time trying to solve problems that we know about but don't already know how to solve. You could give the Collatz conjecture a go, for instance.

HA

I have given the Collatz conjecture and Goldbach conjecture many tries. Specially way back when I was a freshman. Now I am smart enough to know that elementary proofs are not here yet and if I want a chance I need to become a number theory god.

I agree with you, you're just doing this shit for fun. How do you do it for fun though? Due to traumatizing effects of math(getting real stressed over it in the past) I got a hatred of math. So how do you enjoy it so well to the point you get a boner and want to fuck a prime number.

What do we need to happen before living in space is not a big deal?

Is it just a matter of time, are we just waiting for the economics and infrastructure to catch up, or are there some huge technical hurdles?

When will it be inhabited for normies working at the space equivalent of their pleb jobs? How long until I can live and travel in space extremely cheaply, like a space backpacker?

I'm going to assume that space mining is really the big thing that needs to happen, we need resources, we need a lot, and we need them in orbit. Then we can start production in space, and costs will come way down.

I put my conservative estimate to be around 100 years from now, my realistic estimate at 101-300 years and my hyper realistic estimate to be never because humanity will die out before then. Anyways, it is a combo of time, tech and infrastructure that we need to overcome. Space has plenty of resources, but that would cause massive inflation. If we want to colonize space, we need massive changes to our own planet and our domestic problems first.

How do you prove that the number in 28 is divisible by 6? The same goes for the one in 29, but by 19. I've been searching all around the internet how to go about it, but I'm really put off by it.

Also, should this go in the stupid questions thread? If yes, I will make sure next time I will post there.

These are both pretty trivial when you consider the sums modulo the relevant number (6 or 19).

the laws of physics predict, and confirm that ALL antimatter whould cancel ALL matter.
In the beginning of the universe there was an equal amount of antimatter and matter.
So why is there matter?

There's 2 possible reasons.

1. There wasn't equal amounts of matter and antimatter, for some reason.

2. All of the matter and all of the antimatter have not yet met, hence they have not yet annihilated each other.
