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?
User avatar #2923 to #2917 - whatley (09/16/2014) [-]
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.

it didnt proove anything, its just a simple way to show how quantum principles work.

i don't think anyone put a cat in a box for i know
it's a metaphor of how quantum physics works
as in like the chance of electron being in one place can only be a probability

What do you guys think of this? Is what the author claims actually possible, what with things like the heat death of the universe in play?

is this a joke site? ahahahahaha
>trying to get published

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?
User avatar #2909 to #2907 - leightonsolomon (09/14/2014) [-]
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 sci-fi 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?
User avatar #2910 to #2904 - leightonsolomon (09/14/2014) [-]
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

What's the philosophy of math?
User avatar #2911 to #2897 - leightonsolomon (09/14/2014) [-]
All math is is patterns and ways to describe things. I don't know if it has a philosophy, but the purpose of math is to create a language to explain the world. Thats why math and science go hand in hand.

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:
#2888 to #2887 - frikandelspeciaal (09/09/2014) [-]
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 Y-value for every possible X-value?"

When the answer is "yes" the domain is R, meaning that for every possible x-value there is a Y-value.

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 X-value 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 X-value that causes the denominator to be equal to zero.

To be continued...
User avatar #2889 to #2888 - frikandelspeciaal (09/09/2014) [-]

So to find the domain we have to ask ourself: "for what X-value will (2x+1)(-5) equal 0?"

(2x+1)(-5)=0
-10x-5=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.
#2893 to #2892 - frikandelspeciaal (09/10/2014) [-]
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
User avatar #2894 to #2893 - meebobear (09/10/2014) [-]
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.
#2895 to #2894 - frikandelspeciaal (09/10/2014) [-]
So i'm thinking that the brackets are just there to throw people off.
This would mean that the formula can be rewritten as show in the image

So:
2x+1-5 = 0
2x-4 = 0
2x = 4
x = 4/2
x = 2

So the domain is:
X=R: X=/= 2

I hope this the correct answer this time.
#2896 to #2895 - meebobear (09/10/2014) [-]
if that makes any difference. the answer usually starts with "3x+1-5 (bigger or greater than) 0"
pic is an example of question + answer on paper "المجال = domain"
excuse the cam/light and my shitty hand-writing . i was writing fast which adds to the fact that i still have shitty hand-writing ..
User avatar #2900 to #2896 - frikandelspeciaal (09/11/2014) [-]
There are several cases in which a function cannot exist for a certain X-value.

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.

was polio cured or was it weak enough for the vaccine to stop it? shouldnt we atleast be close to the cure for the flu and common cold by now? in reality do pharmicuticals want to make cures for atleast the bigger things or make money off treatments? does scaraway really work? do the cosmetics with plant stem cell work? why am i asking all these questions?

#2884 to #2883 - imtryingmybest (09/08/2014) [-]
what about all the other questions
User avatar #2885 to #2884 - blaaz (09/08/2014) [-]
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)

of course i could be wrong. (but that's a given)

anyone know of a good site to graph vectors by inputting magnitude and angle?

I ended up overthinking the problem and was able to do it by hand
But you are right anyway.....
User avatar #2872 to #2871 - whatley (09/05/2014) [-]
Well that's good anyway.

If I'm honest Wolfram Alpha is probably the worst thing you could introduce to anyone studying maths/physics, shit is literally cheating and you know you'll end up getting lazy and just typing questions into it.
User avatar #2873 to #2872 - Marker ONLINE (09/05/2014) [-]
it's more than useful as a quick tool to get part of a problem solved that you'd need a graphing calculator for, provided you don't have one handy.

sciencexplain ! What's so significant about a mole? (chemistry)
User avatar #2867 to #2866 - subtard (09/04/2014) [-]
1 mole times 1 amu = 1 gram
A molecule of water is about 18 amu. 18 grams of water has 1 mole of molecules in it.

What are the steps to developing a scientific theory? What procedures do the theories go through before they're deemed trustworthy and reliable and universally accepted.
User avatar #2868 to #2865 - 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.
