So someone has posed this question. If it actually has a logical answer, I cannot see it. Does anyone have any ideas? Or do you think someone has just put a bunch of random numbers together without any meaning whatsoever?
>>7811704
Maybe ? is a variable to solve for.
?^3 = 64.8
? = 4.o2 (my zero key is broken and I can't even close these brackets. fk.
>>7811704
If 0.999... equals 1 and the sum of all numbers is -1/12 then OP's equation might as well be true. Math is logical my ass. The system of numbers is flawed.

Hi /sci/,
I'm trying to find the proper categorical analysis tool to test the independence two contingency tables (which you could see as a 3D contingency table I guess).
I have the following table:
CatA1,CatA2,CatA3
40,190,50
200,150,50
90,110,20
(See next post for how I'm visualizing it)
Now, this table is from some point in time.
At another point in time, I have a similar table with different data.
What I'm trying to figure out is how to test for independence of the two tables.
If I just wanted to test the table in itself, the answer would of course be to do a [math]\chi^2[/math]-test, but I don't think that's valid here.
Could you help me out?
Pic related, it's the book I'm using.
This is the format I'm using to interpret the data at one point in time.
I'm not too sure but my first intuition would be this
http://sphweb.bumc.bu.edu/otlt/MPH-Modules/BS/BS704-EP713_Confounding-EM/BS704-EP713_Confounding-EM7.html
I would need to read up. I have that text book available so a page or reference would help me.
>>7812297
Thanks, I'll give this a read through.
It's not actually something from the book, but my supervisor gave me this one to read because he thought it might contain something for it.
I haven't been able to find anything about this kind of comparison so far though.
Hey guys I dont understand a concept, and would like help finding out what its called so i can look it up on Khan Academy or wherever.
Basically its simultaneous equations in 3D. You get 3 equations involving x, y and z, and from them you have to declare if there are no points of intersection, infinitely many, or one unique point.
Basic I know - does anybody know what words I can use to look this up? I cant find it on Khan Academy anywhere.
>pic unrelated
It is called love.
>>7812181
are the equations linear in x,y,z?
System of linear equations? Linear algebra
What is the proper way to study anatomy, /sci/?
I am currently trying to study the muscles of mastication and the maxillary artery. How do I study so as to get a good grip on it? Do I need a skull set? Please help!

Hmm. I have a copy of ballieres anatomy from 1911. It is essentially fine sheets of tracing paper that provide 'slices' all the way through (in my case a heart). I see ballieres still exist, maybe that format still in production?
Anybody good at math like to help with a geocache puzzle? Unsolved for >5 years, and the guy who made it died. I'm terrible at math, so I feel like I could be missing something easy.
I'll post what I have.
Pic related is a two mile radius range of coordinates that should include the solution. This pic doesn't include MGRS cords somewhere around 6VUN53128231
I appreciate any input
Obsolete spelling of the word deceit- with a p
Alright /sci/, let's do some logic puzzles.
>You have to guess the spelling of a foreign man's name. You know that the name is a string of 8 English letters (no numbers or special characters are included). However, the man will only answer "Yes" or "No" questions about his name. What is the fewest number of questions you can ask him in order to guess his name?
If we talk about real names (ones that are/were already given to somebody at birth) then basic binary search through alphabet until using list of names becomes more effective ( for example if its male name and first four letters are alad then you might as well try asking if its aladin)
Or at least that's what i think on avarage would be the most efficient
>>7808488
Does his name have to be discovered in the form of a question, like "is your name _____?" Or do you simply have to produce the name on your own and say it for it to count?
If the latter is true, the answer is zero, since you could technically not ask a single question and run through every possible combination of the 8 letters algorithmically until you get it right.
>>7808488
If his name is actually a name and not just a random string of 8 characters then:
Get a list of all names. You assume this list includes all names.
Reduce the list to only male names.
Start randomly checking (as in is it b? c?, etc.) for the first letter.
Reduce list to only names who start with this letter
Randomly check for the last letters of names that start with the first letter.
Reduce list to only names that end with that letter
Repeat process by then going to the second letter and then the second before last letter, then third letter and so on until your list is reduced to one entry.
How many tries would this take? I don't know, I don't have the list.
gg well played.
What if the darkness the shadows create in the absence of light is the dark matter/energy we are looking for? Would it be possible to measure the force these shadows create?
>>7812023
Thats the thing, the shadows are just the abscence of light where the energy is on our body leaving the shade on the ground. Based on heat alone im willing to say their is less energy in the shadows

If I play chess against a computer it is able to pick out the best moves against me and deduce the likely actions I take.
Given that chess programs can beat even the most accomplished human chess players, do these programs display human levels (not limited to) of reasoning? They are certainly capable of reasoning that can consistently beat human opponents.
I am curious at the progress of artificial intelligence, given that reasoning is a logical process and for the most part as humans we learn through reasoning, making deductions from patterns.
We know that Chess programs can adapt themselves and essentially learn from their mistakes.
Why is it that we don't have more Human-like A.I? What is lacking in A.I? Computational power? Memory size?

>They are certainly capable of reasoning that can consistently beat human opponents.
no
>I am curious at the progress of artificial intelligence
You aren't, or you would be reading journals on it or an introductory book like bishop
>We know that Chess programs can adapt themselves and essentially learn from their mistakes.
Genetic algorithms are especially bad at chess
>What is lacking in A.I?
You can't ask what's lacking if you don't bother checking what's there
>>7811972
Not the retarded op . Bishop book ? Elaborate and would that be after norvig . Also what mathematical background would be preferable

someone told me that self awareness of our own thoughts is like half a second slower than when they show up in an mri. Is this true? He said if he reacted fast enough he could say what i was going to say, thus stealing my trick.
Yes, it's true. Just google the studies.

>He said if he reacted fast enough he could say what i was going to say, thus stealing my trick.
It's must've been some sort of asshole who told you that. That's literally impossible.
The mind is a series of layers, a lot of what happens is actually automatic or handled by the subconscious. The conscious is only consulted when the subconscious doesn't have pre-programmed responses to a stimulus or situation.
A common example of this is when you are driving and you suddenly "wake up" and you're almost at your destination. Your subconscious has the basics of driving down to where you don't need to make a conscious decision for every little action. If an event occurs that the subconscious cannot handle, your consciousness is then consulted. This is when you "notice" something.
The consciousness has a lot to do - it doesn't rely on the ease of pre-programming to respond to situations. Instead, it consults memories, experiences, cross-referencing it with other examples and similar situations to come to a consensus and ends up with a course of action (or no action if you are actively trying to suppress functions that normally occur at a lower level). All this processing takes time, all the while the lower-level functions are doing their best to handle the situation, so you're not completely immobilized/zonked out while making a conscious decision - this is why you don't really notice the 0.5 sec delay.
There is a neat video/series of videos that explains this quite well - I'll try to dig it up.
