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.

> anyone have "a first course of quality engineering" to download?

I looked quite hard and cohld not find it. Sorry. :(

By the way, if anyone wants access to my ebook collection, which is mostly fiction but there are some ood nonfiction books as well, depending on your interest, please come on IRC and get a hold of me (irc.7chan.org or bobba.7chan.org seem to work pretty well) and contact me (deadbabies.) I can usually be found on #channel7 and #7chan among other places.
l have over 10000 books in my calibre library. :3

  I'm not too educated in physics and its principles and theories, but does anyone think that some of the theories of the Standard Model (e.g. Heisenberg Uncertainty Principle, Fermat's Principle) could be ~debunked~ or proven to be false? Is the Standard Model close to perfect? How close is what we know now to fully understanding all of physics?

Anonymous 16/04/10(Sun)02:52 No. 16316 ID: a09f36

I'm basically at the same tier you are or even dumber, but one thing I know is in neutrinos. The SM predicts that they are massless, but from observations they have to have mass. Because they oscillate, they need to have different mass eigenstates to allow for different wavelengths to interfere or something.

Best STEM degree?

I do not think it the best STEM major only if you like money. If you like working with and making new clean technology for others to use rightly then it is a good major for you.

My credibility: I solved the Hodge Conjecture - certainly, proved it at least.

Anonymous 16/03/20(Sun)06:50 No. 16301 ID: 4439d2

Best degree is the one you enjoy. If you enjoy Chemistry but not Computers, Computer Science would be a poor choice.

You have to define what "Best" means.

If it's only money, petroleum engineers are paid well. Computer Science will get you a job, but you'll have to put in a lot of work to stand out. Maths is not so good unless you plan to go into academia, but can be a nice add-on as a second bachelors.

Anonymous 16/04/10(Sun)01:53 No. 16315 ID: bb4d9b

petroleum engineers will either make a shit ton of money or they'll be jobless. It really depends on the market and if there are any jobs available.

How about you kill yourself you greasy phaggot?
It is Easy
There is 4 main components that is essential for your PC
1st A processor(This is what makes your computer run, Without it the computer will probably not function at all)
2nd A Video Card(however some processors have built in video cards in them either called intergrated or APU's)
3rd A Power Supply(Obviously)
4th A Motherboard(This is where all the components connect and unite together)
Start From Learning that and then gradually learn it from sites that can help you such as tomshardware and techguru.

Data storage is also essential both in RAM and HD format.

Why wait until you're in doubt? You should always be going nuclear.

Even Creating a basic Jet Engine is complicated. You cannot possibly make this shit without Einstein's brain

Is STEM good to go into if I like working with yes or no answers. I dislike working with stuff such English where there are many different viable answers.

Anonymous 15/11/25(Wed)03:16 No. 16250 ID: e9dfb1

Actually, although it's usually not possible to find the "best" answer, often it's possible to discern the plainly "wrong" answers, and occasionally two answers can be compared and the "better" answer can be determined unequivocally.
For example, even if I can't prove than an algorithm is correct, if I can come up with various tests that would tell me without question that it is incorrect, and all of them fail, perhaps I can have more confidence in its potential correctness.

Anonymous 16/03/20(Sun)07:03 No. 16303 ID: 4439d2

This should be less a question of "What kind of answers do I like?" and more of a question of "What kind of questions do I like?"

In the world beyond high school, it comes down to a lot more self guidance. You might have instructors asking you questions in early undergrad that have definite answers.

But you're going to get to the point where no one can lead you to the questions you have to answer any longer, and you need to come up with the questions too.

Also, many STEM fields have no Yes/No answers, as it becomes much more of a Why/How/When quandary.

SSID ideas BillyJoeThePianoMan!!HjBTVkMQpk 15/09/29(Tue)00:57 No. 16202 ID: 8aea60 [Reply]

/sci/ give me some "edgy" SSID ideas, I can have up to four or five on my WRT54Gv5 with DD-WRT. I also figured out I can up the power to about 1.6 watts, but cannot get the -o command to turn on "override" where you can set basically any Tx power. Also I can use channel 12 13 and 14 freely :)

Other than SSID ideas that are "edgy" can you think of any illegal (in the US in general or wherever) SSIDs? Just for lulz.

Define "Edgy".

You have up to 32 characters, and might be able to use escaped characters or encoded characters depending on operating system/firmware.

Machine learning for gaming AI? Anonymous 16/02/10(Wed)13:52 No. 16279 ID: 716d81 [Reply]

Hello /sci/!

Let's say that I want to create an AI for a simple board game, maybe chinese checkers. So I record multiple games with 2 to 6 players.

So can anyone please tell me if there's
some program that can simply read the database and construct a gaming AI from it?

What you'd want to do instead is create an agent that understands the allowed moves. Use multiple agents to play against each other. Incentivize the agents by assigning weights to different conditions. Things like -1 point for losing a piece, +1 for taking another player's piece, -100 for losing the game, +100 for winning. Then let the agents play each other a couple hundred thousand times and store the patterns.

The system would then follow paths in a decision tree for each state of the game to the next state, following the higher point paths.

What you've described (The recording and analyzing would be a very minor part, and observing enough games to program an AI would be difficult if they were real games.)

Other options include incentivizing other goals, like control of the middle of the board, or attacking the player with the most pieces. This could lead to other strategies that the system could then utilize.
