New Textbook/Book Request Thread deadbabies ## Mod ## 13/08/25(Sun)06:03 No. 15270 ID: f34135 [Reply] Stickied

First off, hello there, I'm deadbabies, and I will be taking over as /sci/ moderator. Rules will remain the same. Please use the report function if you see posts that violate the rules, but also do not abuse it.

I have officially expanded the scope of /sci/ a bit. You may discuss Science, Technology, Engineering, and Mathematics here now. No science is discriminated against as long as it's of the peer-reviewed variety. If someone wants to discuss Anthropology or Social Science, by all means, let them. If you do not like it, just don't post in the thread.

The IRC channel #/sci/ is now (finally) re-registered and I am running as operator on here. Feel free to stop by and say hi. I do leave my computer idling on IRC, so check back or leave me a message if you have any ideas, suggestions, or just want to tell me off. You can get onto #/sci/ by joining the server irc.7chan.org at port 6667. You can also use SSL at port 6697 but you will have to set your client to accept invalid certificates.

ADDITIONALLY and IMPORTANTLY I have had several requests on IRC regarding the old Ebook FTP that we used to have. Unfortunately, the mod who ran it entered the military and no longer runs or maintains it. I have no plans to make another one, but if one of you guys would like to, by all means advertise here.

That being said, I'm just going to leave this link here:


You may find what you seek here.

I will be unstickying the old ebook/source articles thread. Please post any new ebooks/source articles here, and feel free to post any working links from the old thread there; I will eventually be deleting it.

If you flip an asymmetrical two-dimensional Flatlander through the third dimension, his right side will become his left side and vice-versa.

Let's say you did something similar to a person, flipping him through a fourth spatial dimension. The problem with this is that the flip isn't just his body parts. The molecules in his body would be flipped too, and many chemicals have asymmetrical molecules which take on different properties when mirrored.

So taking this into consideration, would this flipped person even be able to continue living? Would his death be immediate or more lingering? What effects could we expect to see? Take me down this rabbit hole, /sci/.

>So taking this into consideration, would this flipped person even be able to continue living?
Can your flatlander survive being flipped?

Most of this comes down to how you handle the flip, as a rotation or an inversion. If it's a rotation not much changes from our perspective, if it's an inversion, being turned inside out is not pretty even if you are put together again afterwards.

Anonymous 14/12/17(Wed)04:41 No. 16001 ID: 465a65


Well, the question presumes survivability of the flip.

Anonymous 14/12/20(Sat)20:25 No. 16004 ID: 86e5d5

Results aforementioned witness is history by I. To do is attempted number attempts however unsuccessful is results. Asymmetrical molecules exist partial functioning however deficiencies aforementioned deliver propagations expectation aforementioned. Grand wish is trustworthiness of intention harmless. Grand wish is trustworthiness relations.

When Apple does something big, and it does what it's designed to, I love them for doing it, it's great.

The rest of the time, their conservatism pisses me off so bad I almost hate them. My god the effort they put into their software, just to be able to milk the fucking hardware specs for God damn ever in their product line. Yay for more eficient software & hardware, & bang for the buck, but shyyyyyit, Selling non-upgradable notebooks with 8GB ram & non-retina displays in 2015??? And nice fucking iPad mini update. Same exact model as last years, plus an only half-functional touchID sensor... And still no fucking TV. God dammit.

neither. if I had to choose, I would choose Microsoft. But already heard of the Fedora system? It's a simple, open, secure, and stable system.

So for everyone out there I ask you what you think the universe would be like if attraction was different. If it was likes attract and opposites repulese, so two positive charges attract same with negative and then a positive and negative repulse. What do you all think?

My guess would be not much change at all in terms of how the universe works, entropy etc.

But would we exist in it? Probably not.

Effectively you are just switching the masses of electrons and protons. The atomic structure would remain relatively similar except for heavier electrons. Would this cause them to orbit much further from the nucleus? I don't know I'm not a physicist.

But yea, if atoms functioned similarly to how they do now then organic life would be very different. Depending on the properties of the new elements it would likely not be carbon based but rather a more suitable element

I think this was explored as a mathematical possibility in the early universe when antimatter still outnumbered matter a buttfucktruckload to one, and much weirdness abounded.

I forget what all went down but in short, that shit worked briefly, and then worked itself out. It... went away, OP.

  Everything I've read about Eugenics has been about how it's pseudoscience. Ok. but, by the sound of it, it was just a selective breeding program. If artificial selection works in every other species, and natural/artificial selection has produced us, ...where's the problem exactly? I have yet to see how a sophisticated selective breeding program couldn't produce a better human body or brain or both. It's what we do every time we pick a mate who we think will make us some primo offspring.

pic semi-related: Just try listening to this without clawing your eyeballs out (why are so many people so fucking retarded and how can we replace them with upgraded models?)

I think a better alternative would be like what appears in the movie Gattaca. You take many gamete samples from the future parents and fertilize them in vitro. You keep only the zygotes that meet certain criteria for health (optionally freezing a few in case of miscarriage or some other problem) and you implant one in the mother.

Anonymous 14/11/30(Sun)21:20 No. 15990 ID: 96b946

What about unintended consequences?

Like, for example," Oh hurray! We have bred sickle cell out of existence! But wait oh fuck now everyone is dying of malaria"

Or like how rainman idiot savants are a cunt hair away from being the next Issac Newtons.
Get rid of the retards, get rid of the possibility of greatness.

Anonymous 14/12/01(Mon)04:19 No. 15991 ID: 86e709

The downs side of that would be no greatness, unless, oh shit, a whole generation of autistic savants... because who cares, it eliminates war, and robots and androids unburden us from the shackles of menial tasks and physical labor, agriculture, maintenance, freeing us up to contemplate mathelamatiques and phirosophry and awwt aww day. They can all be sterile, finally uncoupling sex from our reckless primitive approach to reproduction, so people can mate purely for social purposes. Reproduction only happens when intended and it the parents are committed, stable, and financially sound to care for the young, in addition to engineered fetuses cleaner, healthier genomes.

Plus, bonus upside, all cunts can easily be hairless cunts.
