Hey guys. Not asking you to solve it for me, but my colleague in the Mathematics department of my University challenged me to solve this in a week(I'm a Computer Science undergraduate student). I don't even know where to begin. Could someone direct me where to go to read more about this type of problem, or even give me the name of the mathematic principle being applied? Thanks!
>>8007428
what's the process?
>>8007428
This is not correct
This means 99% of this board is smarter than Feynman. Discuss.

I have (supposedly) IQ of 156, but I never pursued career in /sci/ related areas.Such a shame.

Elon Musk thread. Discuss politely.
>>8006691
Sure.

Elon Musk is too proud to be successful in the long run. I'm almost certain he only keeps going on by stealing other people's ideas.
>>8006719
That's funny considering he gave away all of his Tesla patents for free
So what's the point in studying science again?
Since nihilism is the cumulative consequence of a rational/scientific approach of life, and that pursuing logic eventually leads to the realization that reason and logic are both worthless and equal 0. Isn't all science worthless? Is there an objective reason to pursue science that isn't emotions or self preservation?
>>8006505
>Since nihilism is the cumulative consequence of a rational/scientific approach of life
not really correct though is it? it's still a very grey area but pop-sciencey types like to make it out as if the big questions have all been resolved.
If people were more honest they'd admit that they just don't know but the current fetish is to act out the super rational atheist/nihilist a la dawkins.
if this is bait you could at least make an effort.
>>8006514
I see your point, but the idea that life is meaningless isn't as farfetched as you make it out to be.
Just take the scale of terrestrial life compared to the size of the universe, only that makes all terrestrial life negligible. Working with the most probable outcome inevitably leads us to nihilism
>>8006505
If you get joy out of finding stuff out, then why not do it?
Can someone explain when life begins? I know that it begins at conception but can someone go more in-depth or something?
you already made a thread with hillary posting here buttboy : >>8005717
If you're going to say it begins at conception, you might as well say it begins when sperm is manufactured.
>>8005767
Well, it's pretty complicated and depends on what definition of life you use. I say that a human fetus is both alive and a seperate entity when it can survive outside of the mother's body without the mother (technology is fine, I just mean living without being in the mother's uterus). So, this isn't a great definition because that definition will change a technology progresses. Another good definition is the existence of the brain. Of course even that definition is somewhat complicated, but I use the definition of a basic human neurostystem. This has not formed by week 7 or 8, so I feel very confident saying that abortions that happen by this time are not murder (65-67% per http://www.abort73.com/abortion_facts/us_abortion_statistics/).
Query:
Has there been any research into whether or not homosexuality is a result of chimerism (two eggs produced during ovulation, nonviable embryos break up and come in contact with implanted viable blastocyst, which in turn absorbs and incorporates the DNA of the non-viable twin into its own structure)?
Natural selection generally, given enough time purges traits which do no provide advantages and increase the probability of survival of a species. Producing a product which is predisposed to not reproducing would seem to be not only self-defeating but possibly even dangerous to the continuation of a species if it ever caught on genetically. True most non-beneficial genetic traits seem to die out eventually. Homosexuality which is chimeric doesn’t really fit the definition of an inheritable trait. It is not the mutation of a single gene which can be passed down to subsequent generations. It’s not a single thing. It’s part of life’s ability to successfully incorporate more variety into a single organism than meiosis is able to do on its own. Chimerism is an extra added, unexpected bonus of the cycle of life which wasn’t even discovered until 1953 in humans. This seems to support that chimerism is a more likely cause than the popular "gay gene" idea.

Any biologists here?
How do we eradicate the gay gene ?
>>8005737
Biology gradfag here. I'll try to do this justice, although I'm more of a bench scientist than a theoretician. Although this is certainly interesting, there are more parsimonious explanations biochemically and genetically for complex behavioral traits such as homosexuality.
Chimerism is presumably the result of a random process, although recent research has found several loci and related alleles that seem to predispose carrier females to have twins at a higher rate. There may be something analogous with chimerism that we haven't found. Evolution works slowly on biological systems that are excessively noisy (random) or dependent on nonlinear interactions. Chimerism is by definition a highly stochastic process and is likely limitedly evolvable at any meaningful rate. Also, true chimerism likely occurs at a much lower base rate than homosexuality. If you want to argue the role of microchimerism, that may be a different matter.
All in all, epigenetic effects such as histone modification are theoretically more likely and experimentally better supported biological correlates of homosexuality. Epigenetic programming is limitedly heritable, if at all, while still affecting an organism's development in utero and beyond.
While epigenetic processes may themselves be under evolutionary selection, the traits shaped by epigenetic processes are not directly heritable in their entirety, as epigenetics implies the physiological processes resulting from exposure to one's environment. This is likely a better explanation of why homosexuality has not been subject to negative selection.
Hey guys,
how many of you are here, browsing and reading a lot, but never really post anything?
Why you browse /sci/?
And why you don't post?
I browse /sci/ because I've always been interested in sci-fi related stuff, than had some advanced math classes in high school, learnt a lot from my physics classes about a science and there is lots of really amazing stuff about it. Than dropped it completly, went to law school, got law degree and I'm now a layer.
Now that I have more free time I became again more interested in some physics and science, started reading Fenyman physics courses and re-learning calculus. Came here to get some opinions about current high-tech/transhuman stuff.
I don't post here because although I learn a lot from you guys, often question your posts in my mind, I also don't think I'm on your level, /sci/entists.
Thanks for being here though.
How about you, other non-posters?
>>8005616
I read this place as pure schadenfreude. The posts, posters, trolls, and futurists are denser than the core of the black hole shitposts that clog the board. I literally cycle between this one and /r9k/ just to reassure myself every night that coalesced retardation exists and that I know its location.
>>8005658
oh come on, they are not that bad.
Most of them are pretty smart, just trolling around.
>>8005678
Let's take a critical tour of the /sci/ catalog as of the beginning of this post, shall we?
>AI replacing all jobs in 10 years
trolling thread, not particularly inspired
>Redpill me on GM crops
shitty baseline pandering troll thread
>This topic
where I'm shitposting the entire board at once
>Simplified highschool physics backpatting thread
no one cares asshole, otherwise we'd all major in calculating parabolas for throwing rocks
>Questioning the moon landing topic
troll topic, though small chance that it attracted a retard thinly veiling fuel for a moon landing denial post on a different board
>Time travel thread
horseshit popsci garbage
>Gay gene discussion
shitty strawman for an argument that topic's OP isn't qualified to discuss, also trolling (badly)
>Bigelow thread
Fine.
>Why can't aliens be dumb instead of smart?
It's a longer OP, and the reasoning is superficial, banal, and surface-level
>What are dreams?
A long list of things that you could google if you bothered to.
>Stupid Question Thread
The eponymous thread.
>Making fun of their old highschool prof
Move on idiot. Also shitposting.
>Why haven't we cured cancer yet?
Bait thread.
>I don't understand the calculations behind the diameter of the universe.
Which is the stage where you re-read until you understand or have a more specific question instead of shitposting on a board where you won't get a reasonably summarized answer.
>What calculator app should I buy
Fine. Probably a good scope for the question.
>Redpill me
Trollbait
>Calculus is not advanced mathematics
Trash bait. Odd that some legit discussion of even basic problems happened here.
>Is my textbook a meme
Your shitposting certainly is.
>Sun of ice Sun of Lava
old
>mars colony
popsci futurist nonsense
>online color ""test""
first incidence of this to come up so far, but people linking vomit-ridden online tests is more common here than other boards.
I could go on.
Hello /sci/.
I am a GED holder who while looking for a new job, am in the process of trying to better myself and make myself a more intelligent and productive member of society.
As such, I'd like to begin picking up new mathematical skills and learning more about how the world works. For example, I'd like to learn about the following:
>Astronomy
>Algebraic Thinking(I suck at Algebra. Would like to improve.)
>Calculus
>Mathematics in general(I barely pased the math portion of my GED test, suck at multiplication, can't barely do shit in my head. Would like to improve tihs.)
>Biology(?)
>Physics
>Anything that you can recommend me to make me more smart
How long would it take me to get a basic grasp of all of these things and/or basic concepts? Or useful concepts?
Thank you /sci/. I look forward to improving myself.
>>8005368
Oh also, this is more in line with /lit/, but I'd also like to work on improving my vocabulary.
I should probably have posted this in /adv/, but the things I'm looking on improving and learning on are mostly /sci/ related things so I figured it'd best be a topic for this board.

Stephen Hawking, Mark Zuckerberk and Yuri Milner propose making a solar sail nanocraft wich will reach Alpha Centauri in 20 year.
What do you think about it /sci/ ? are they serious, or just dreamers ?

What I don't understand is why this is big news now...http://www.deepspace.ucsb.edu/projects/directed-energy-interstellar-precursors
The idea has been around, and there are more implications to be made past sending a microchip to another star, but I guess everyone gets all hot and bothered when the nugget in the wheelchair says anything.
>>8004482
Well it's mostly because they also have the money to do it
Is global warming real?
>>8004030
Obviously not. It's a Chinese conspiracy to hurt the heart of the motherland America's industry.
Of course not, the world is flat and so is its temperature.
energy runs the world, the fact that we're on the cusp of being able to get it for less than we have been has made a lot of people nervous
the saudis are silently finding isis as a land grab in response to this
the sooner we stop dealing with these people the better
china know exactly what they are doing
Can you guys explain how the u.s made it to the moon. I can't find a clear answer how.

They flew there on a rocket-ship.
Memes travel fast, yes. I can deduce this much myself. But to what extent?
Speed of meme spread is directly proportional to the population size and spread methodology effectivity
>>8000440
There is an unknown factor which affects the validity of our measurements, something that we don't seem to be taking into account.
We call it dank matter / dank energy.
>>8000444
In addition, the the speed is largely affected by disturbances in the environment in which the memes propagate, such as influence from other societies and even the local climate, which may lead to changes in lifestyles and, consequently, cultural practices.
What my courses look like:
> Analytic Geometry & Calculus
> Multivariable Calculus
> Metric Differential Geometry
> Numerical Solution of Differential Equations
