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 suffer from insomnia, then I can imagine how much it interferes with your life. I had insomnia for a long time, but I eventually solved this problem with cbd gummies. In general, you can choose any form of cbd, this online store https://www.cornbreadhemp.com/products/full-spectrum-cbd-gummies has a fairly large selection of cbd supplements, but cbd gummies are my favorite because they are delicious.

Hi, /sci/


This article talks about how psychosis and sexual trauma can cause gender and sexuality confusion. I suspect I have that but I'm worried if I talk to a therapist about it (or anyone else for that matter) they will try to "affirm" it, which I don't want.

Does anyone here know a "renegade" psychologist who can help me?

Can it be reversed?

I remember hearing about a theory that homosexuality is caused by intestinal parasites wanting to propagate themselves through gay sex.
Does anyone know anything about that? Is there any research on it?

Hi sci,
I'm a noob about computers and going to do college of Computer Engineering. I don't know even how to start learning. Can somebody give a tip?

Senior in electrical engineering here (computer and electrical engineering share about 50% of their curriculum at my uni)
What others said, building a PC is a good idea. I've never had enough money for a PC though and have been coasting through college with a ditched laptop that I fixed.
One hobby I took up when I was figuring out what to study was getting obsoleted PCs off surplus auctions or from family members, lobotomizing them and experimenting with linux distros. You can make your own servers for storage and mail etc.
Another thing to play with is RaspberryPi and/or Arduino projects. There's tons of resources on those and honestly should be the focus of practical teaching in universities (but often aren't)

Can someone explain a quadratic equation in a way that makes it more intuitively understandable? My algebra teacher just rambles endlessly about unrelated shit.

sorry, in the 1st example I wrote (f(x)=0 when x=1)

Whoa, I just saw this the other day while I was looking for a comment I made in the seventh page.

Dude, you're responding to a question from three years ago. I'm sure OP has since learned what a quadratic equation is, or they don't care anymore.

Your method seems a tad too complex for my liking. Why do you think it's better than simply remembering
x = (-b (+/-)sqrt(b^2 - 4*a*c))/(2*a)
? That's a single formula that solves any quadratic equation in a single step.

Now it's even farther in the future and the quadratic formula hasn't changed a bit. I hope OP is ok.

I have forgotten everything I learned about physics in secondary school.
Why does this not work?

>The force between permanent magnets is conservative as the magnetic field follows a potential, so that there is no work done over a closed cycle.

In other words, the magnetic field is shaped like a valley. You can extract a bit of energy from it by falling into the valley (energy you stored when you climbed out of the valley previously), but if you're simple circling the valley without ever reaching the bottom then you're not extracting energy, and certainly not an infinite amount of energy.

The prime movement of humanity is superheated plasma of cosmic background radiation, puppet stringing along blood pressure and the 4th-dimensional potential of water consumption.

Horsepower alone can be derived as a dimension of life through pressure dynamics alone.

But my real secret is most of my family has been saved by surgery and medical science. I never touch a hospital bed. I have other secrets.

I am just happy to escape as a Zen monk on fire.

I am Ra. We are not happy with our Venusian scientist claiming he is not helped by any here for this. :)
