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.

Sorry, but this seems like an actually interesting topic to me recently. OP is not clickbait.
I am personally found similar sound frequency videos on youtube, with different combinations of specific waved, masked with "ambient" or not. For example this: https://youtu.be/g6SlLCyrHyU?list=UU16NNFKodOsrgi0Nla5XPKg
The description says 852Hz 936Hz 963Hz, but how exactly these waves affect people's brains and stuff? Was going to make kind a deep research of this later, but stumbled to this thread. Wonder if anyone knows, thanks.

Hi folks. Sorry I am not sure what is the best to post this.
I'm here to quickly ask, if there are any serious damage to linux done by that SJW bullshit yet.
Heard of this story year ago actually month after it happened. Haven't updated mu lubuntu system since. Not really following linux forums and shit.
So what's happening, is SJW shitfucks totally destroyed my linux yet or not? Have this wallpaper I edited. Thanx.

I wouldn't worry too much, you can always roll back updates or download the current version you're using from the archives and reinstall.

This isn't windows.

Hell, you can always boot a liveCD of the latest version to see what it's like then scrap it when you're done.

If this is what is programming ai we are doomed. This is obviously a traffic light even to retards. This is not my personal captcha bc I forgot to save it but it's how it always is, obvious ass shit.

My second point on this is the tech business is mostly a fraud giving hopes when they have dumb products without any innovation. For example, Musk is building a subway tunnel and calls it fancy names bc retards fall into it. Most know but look at thunderfoot videos if you don't. He's an asshole but he does the work.

If you want to get rich make a company with a good liar and give absurd claims as if they are trivial. All the retards will fall into it, just like solar roadways.

Final thoughts, silicon valley show, it has no real money making platform bc it's been done already in the form of many projects that aren't out for money bc they are basically bit torrent sharing platforms. Once you let it loose in the wild your only getting donations. In reality the corporate part requires cloud based systems to control the content.

Do you have a job? Did you get an education? If you did by now you should have realized that a lot of the world is redundant stuff and bullshit you have to sell to uninformed people. Where there is a lot of money to go around that's what happens, for example the western half of the US like Texas and California.

Sure this isn't where the real progress is being made but it's easier stuff that gets around and what industry will expose to normies.

1. You don't have weapons-grade uranium; stop larping.

2. 100 grams isn't enough to do anything with.

3. If it were, since you're a retard and put it all in the same place, it would have gone critical and fatally irradiated you.

The Vaccination of little Tommy Autistic.

When Tommy was a wee little lad at 4 years old, his mommy took him to a tax payer funded doctor's office to get a "booster shot." Little Tommy had no idea what a booster shot was, but he went in excitedly, mostly just because the waiting center had a little play area for him and other kids to play with blocks and such. It was then, when doctor told Tommy's mommy that it was time for Tommy to get his first booster shot! As Tommy sat down on the white papered bed, the doctor approached him with a big scary needle. OUCH! The needle pricked Tommy in the arm, and Tommy could not stop crying. The needle hurt Tommy, and Tommy had no idea why his mommy would let Tommy get hurt by this strange doctor. You see Tommy's mommy was a feminist in the 1960's who took part in the "revolution" for "female rights." She used to be what people would call, a "hippie," but after all her youth experimenting with various drugs, she decided to take her chruch's big business funded AA program's advice, and settle down and have a kid, in order to put her life back together. While she was in school, she "learned" that "vaccines eradicated disease" because they are "disabled" virus DNA that serve as target practice for the immune system's anti-bodies, so that way the immune system would be extra ready when a "live and active" version of the virus came around. She read in her government funded biology book how a Jewish doctor, Edward Jenner, "figured" this all out because his milk maidens, who were regularly exposed to cowpox, were relatively immune, so he created a concoction out of small pox pus, which contained the remnants of the disease, and inserted the pus into people's blood streams! It was all so sciency and believable to Tommy's mommy! After all, why would she be going to school if all this stuff was not true? Tommy's Mommy's also learned about diseases like polio and rhuebella, and tetanus, and measles oh my!

There are two brains in people.
Firstly the chemical brain we have had from the first splitting of one cell into two.It handles all the main duties in the body . Then we develop a consious brain and at about 5 it starts working and we think we are gods from there on.
The chemical brain is a combination of our Liver and other organs and the inner part of our brain where the outside environment is sampled for dangerous viruses germs etc and antibodies made ready to fight any invasions quickly. Any injection is an invasion into the body and the body must overcome it or die. Everything evolves to do better at its task and so do we or we would have been left behind a hundred million years ago.

c=nu*lambda; nu=frequency and lambda=wavelength
The unit of frequency is cycles per second and that of wavelength is a displacement. Therefore, dimensional analysis provides you with displacement per second. Also, many electric and magnetic fields travel at speeds different from the speed of light, both faster and slower. Faster ones make it out of black holes, which ones depends on the escape velocity of black holes. The question you want to ask is how can we know theoretically that the matter eaten by the black hole conducts, and well, which we know from the electric and magnetic fields that escape from it near the axis of rotation.

quantum physics is stupid. waves, quants, photons. blah blah. it doesn't make any sense. physics in this regard is a giant bloated mess full of convenient mathematical tricks, but there is actually no real understanding, because no real observation can take place at this scope.

Anonymous 19/08/06(Tue)02:24 No. 16826 ID: 051d67

C The speed of light is used in many formulas as convenient shorthand for a bloody big number. The bigger the number the harder it is to prove it wrong and the closer to actual it will get the maths. Einstein used it to jump over the true speed of light .

Quantum theory is just that and draws a lot of funding for university layabouts to spend on themselves . Little will ever be achieved by quantum theory . For example it can be proved in quantum mechanics that black is equal to white with a 99.99% probability. Now if that's not stupidity extreme then I'll eat my own balls.

Hello /sci/. If there was a giant hole in the earth leading from one end to the other and- if you jumped in- would you just be pulled to the other side, or just be trapped in the middle by gravity?

>people still doesn't know how gravity doesn't work

If there was a hole like that then the planet would just merge back into a ball because o gravity. Let's say it doesn't then it means the whole planet somehow lost a lot of mass which means that the planet is going to fall to you because your gravity pulls it to you.

Anonymous 19/08/06(Tue)02:12 No. 16825 ID: 051d67

If a hole were possible then common sense says jump in ..fall to the center at ever increasing speed past the center slowing down all the way to the outside rim but not quite far enough to grab the rim. Fall back in again and out again loosing a bit each time till stuck in the center.

Falling into a black hole would be different .Falling Falling Falling Faster Faster Faster SPLAT!
