Hi guise,
So I'm in my third year of university, I'm working on a biology degree. Since you read that last sentence you obviously know that english isn't my native language, that's why I have an English class.
Here's the thing: I need to make an english presentation about a somehow scientific subject, and I wanted to do mine on a cool social/psychological experiment such as The Milgram Experiment. For those who don't know what it is check it out, it's pretty cool: en.wikipedia.org/wiki/Milgram_experiment
So I was wondering if any of you knew one that was really interesting or knew where I could find some. I just started lurking on sciencedaily.com and explorable.com but of course I ended up on funnyjunk.
(I'm posting this on /social/ too, let's see which board is the best)
Thanks guise.

So, I've heard some explanations on this but I'm still not entirely sure about why.
What exactly did Schrodinger's cat prove, what was being tested, How did putting a cat in a box that randomly fills with neurotoxin forward science?

Schronginders cat never actually happened it's a thought experiment about the interactions between quantum and Newtonian phenomena. The whole point of it is to show that quantum laws and Newtonian laws cannot be resolved with our current understanding of them.
A particle can be decayed and not decayed at the same time.
This causes the toxin to be released and not released at the same time, and therefore the cat to be dead and alive at the same time.
Obviously the second part doesn't make sense, a cat cannot be dead and alive at the same time, showing that quantum and Newtonian laws are different and interact with each other very oddly.

first of all she doesn't know what spontaneous means
second of all, even if out bodies "spontaneously" reconfigure, it's not gonna be you
just like how if you make a sandwich, and make another sandwich that's atomically replicate of that, the first sandwich isn't gonna be the second sandwich.
they're 2 different sandwiches.
3rd universe isn't infinitely reconfiguring, if it did, there would be no need for science. because it would mean 1 + 1 today may be 2 but tomorrow it's gonna be 3?

Its interesting but doesnt make much sense. Even if the atoms reassembled themselves in the EXACT same way, it wouldnt be the same consciousness. Its just like you can make a computer with certain information, and create another computer that is an exact duplicate. Each computer is still itself, even though they are exactly the same.
And yes, the universe WILL end, but in a ridiculous amount of time.

This "theory" is full of shit.
If you've watched some scifi it's not hard to imagine recreating consciousnesses. However, if you have any level of understanding of chemistry you will have a lot of issues about the spontaneous part.
These are the kinds of hypothesis that has to resort to "exotic particles" to support them.

Would it be possible for Artificial Intelligence programs to "reprogram" themselves?
I've been reading some of those news articles on the dangers of ai in the near/far future. AIs going to incredible and dangerous lengths to fulfill their programed duties. But if these machines are in some sense intelligent, ( I know this is a bit of speculation than anything) would/could they even consider altering their programing/code/whatever? I would imagine there would be precautions for preventing a computer to make adjustments for itself, but we are talking about supercomputers that are crazy smart.
what do you guys think?

Computers and programming get more and more advanced but they will always follow the same principles and rules (as long as we are still using electronic computers and not quantum ones or anything crazy). A section of code could alter other areas of code, but not itself. Computers are already coding programs by themselves, but none can recode themselves. That would be like erasing instructions to put in new instructions. I hope you get what I'm saying. I'm an amateur programmer

Find the domain . also the fuck is this shit around the "2x+1" in math?
i never liked math , never did good at math guess its my time to shine as my teacher gave this question to the class in the last 10 minutes with a prize of full mark for the whole class.
no one answered . so he made it a homework with a prize of 2 marks for who solved it.
Find the domain . the question ends somewhere when we find the domain which usually goes like " f =R : f =/= something" for example.
HelpMePls D:

Y=F(x) means that the value Y is a function of value X
This means that the value of Y will vary depending on what the value of X is. The formula you've given shows the relationship between X and Y
This relationship will often be displayed using a graph (pic related).
When people ask for the domain of a function they are basically asking : "Is there a Yvalue for every possible Xvalue?"
When the answer is "yes" the domain is R, meaning that for every possible xvalue there is a Yvalue.
However, in your example the anwers is "no".
Whenever there is a X in the denominator of a fraction it will be possible that there is a Xvalue that will cause the denominator to add up to zero.
As you might know, dividing something by zero is impossible, meaning that the funtion Y won't exist for the Xvalue that causes the denominator to be equal to zero.
To be continued...

So to find the domain we have to ask ourself: "for what Xvalue will (2x+1)(5) equal 0?"
(2x+1)(5)=0
10x5=0
10x=5
x=5/10
x= 0,5
So if you fill in 0,5 into the formula you will find that the denominator will equal 0, meaning that F(X) does not exist for X= 0,5
So the domain is:
X=R: X=/= 0,5
I hope this explanation makes sense, if you have any more questions i will do my best to help you

the answer seemed so logical tbh.. showed it to my teacher at the end of the class . he said it was wrong and i was like "oh okay . went back to my seat" .. didnt even ask him why ._.
ill make sure to get the right answer tomorrow
thanks for your reply tho. really appreciated.

Is that the way your teacher gave you the formula? Because i might have interpreted it wrong.
Does the denominator say: (2x+1) times 5
Or does it say: (2x+1) minus 5
i'm not sure why he put so many brackets there
Also, did he tell you what the right answer way? I'm really curious as to why i fucked up

he did it exactly as the first one . we asked him the fuck's the brackets. he just looked at us and said the prize of the question :/
also he didn't say a thing about the right answer. so i suppose he'll still give marks for the right question :3 ill ask him the first thing tomorrow.

There are several cases in which a function cannot exist for a certain Xvalue.
The first one i mentioned is when the denominator of a function becomes 0.
Another situation is the square root of a negative number.
When a square root is involved, you will know the function will exist as long as the contents of that square root is greater or equal to zero.
So in your example the domain goes from 5/3 to infinity, because as long as X is greater than 5/3 the funtion will exist.

Well for those i personally think that i don't know enough about the subjects to give a accurate response to them. I apologize for that.
I do happen to know a little bit about the "cold/Flu" one though (anyone feel free to correct me if im wrong)" From what i understand about the cold/flu is that they often mutate in a sense that they swap genetic information between other versions of the "cold/flu" which would mean that each mutated version is technically a completely different disease yet still function in a similar matter.
( cures for diseases to my knowledge work like keys do to locks. If the "teeth" inside the lock are changed then the key/cure wont work for that modified lock)

coronus (09/04/2014) []
A good theory is based on experimental evidence or mathematical proofs, and critically analyses the available evidence in such a way as to provide an explanation for how it fits together or what its cause was.
This starts as a hypothesis, with the expectation and responsibility to gather novel evidence through rigorous scientific methods, in order for hypothesis to become theory.
As a theory, it will only become accepted when a substantial amount of supporting evidence is gathered, little good disproving evidence exists, supporting results can be consistently replicated, and opposing or alternative theories are either less concise or garner less compelling evidence.
