Greetings fellow scientists !
My domain of "expertise" is computer science, therefore i'm a complete beginner regarding chemistry.
But still, i am very interested into knowing a simple fact.
Can one produce, create, assemble [...] a chemical entity (such as a molecule) that will interact with a specific chemical entity, let's say Melanin.
The objective of my question is to know if a chemist with his own lab can create some kind of gaz mainly composed of a molecule we'll call "Molecule A" that carries another molecule...

I'm going to stop you right fucking there.
>>8163310
Apologizes,
Then let met re write that part :
"Greetings fellow /sci/ browsers,
I'm a software engineer, but i'm interested in chemistry."
Is that better ?
I see where you're going with this OP. While I'm unable to help you, I'd like to wish you the best of luck.
How would someone score a perfect on the ACT?
by solving all the problems
>>8163305
Solving doesn't mean you have the right answers.
by getting all the right anwers then .-.

Elder Scrolls III: Morrowind has several coded messages. Most of them have been cracked, but a few remain a mystery. These are orders for an agent of an organization called "Hlaalu" named "Bivale Teneran" in the city of "Ald Ruhn."

Hey /sci/
What are the prerequisites or math I need to understand to get into learning differential geometry? Also what are some good text books for self teaching?
>>8163135
Differential equations and geometry.
...
Yup.
>>8163135
Multivariable calculus and linear algebra.
>>8163152
Diff eqs aren't that important. You only need to know that if everything is sufficiently well-behaved, then the equation has a unique solution.
Have there been any scientific studies on how fiction influences our mind and behaviour?

it all makes sense now.

You know. The sad thing is many textbook authors have actually said similarly retarded things.
>>8162952
I take it you're an engineer.
Red-pill me on spooky action at a distance.
How can it be FTL and why can't it be used to send information by morse code?
>>8162802
>Red-pill
Go back to your containment board, retard. Nothing can be gained by educating you.
>>8162802
It can't be used for communication of information because the information is already effectively and transmitted when the systems interact before they are separated.
In some sense it's like taking two boxes, putting a red ball in one and a blue ball in the other, moving them apart, opening one to find a red ball and then knowing that the other one has the blue ball. You can't communicate with that.

El Nino ist tot. La Nina chances this Winter are increasing. Development likely this late summer into autumn. More at http://www.cpc.ncep.noaa.gov/products/analysis_monitoring/enso_advisory/ensodisc.html
>What is Summer?
Summer is the warmest of the 4 seasons. Meteorologically, it is the months of June, July and August (December, January and February in the Southern hemisphere). It is caused by the increase of daylight time and the Sun's higher altitude in the...

Let's try this again- I'm working in a Mountain Met lab and I've been doing some visualization work on thermally driven flows. This is from the model work that my post-doc adviser was doing, feel free to ask me anything.
>>8162681
(just remembered that that graphic technically isn't my property, sorry. Still feel free to ask any questions, related to either the modeling technique or what I'm working on.)

As someone who has only checked up on this board maybe once or twice; Why are Mathematics, Physicists, and Engineers so split with each other?
Doesn't Math help Physics, and Engineers use those Math Equations to help with designs?
They're all incredibly important when it comes to the universe and not having all three would learning about it impossible.
>>8162632
It's a college thing.
Engineers are usually condescending fags that think their memorization and applied classes makes them more useful.
Physics thinks they know the answer to existence and everyone else are their tools. In reality they party a lot and get high.
Math students are autistic about their rigour.
This is amplified 1000x on an anonomous Anima board
>>8162632
People who do math usually don't care about physics or engineering applications. If anything, we'd prefer never to see these applications, because it ruins the purity of the subject, there will be interest in a problem because it's useful rather than because it's interesting. Pic related.

To make meaningful contributions to math you must have the right kind of autism. If you don't have it you'll never be great. Even if their work is unintelligible to pretty much anyone but other mathematicians and useless by basically any standard, it is important that anyone capable of advancing math do so, simply because most people are not intellectually equipped for it. Math is it's own reward, although nothing stops one from cashing in on poker or the stock market.
To make a meaningful contribution to physics you need to learn about as much math as a professional mathematician then work your ass off trying to figure out a way to use some of the higher math you learned to model the real world. The best physicists are world class mathematicians and may even need to create new math branches to solve problems posed by the complex nature of reality. Even if you are not great you can still become a meme scientist if you are charismatic enough. There is a great risk of wasting your life working in an hypothesis that simply doesn't correspond to reality.
An engineer doesn't need to be particularly good at math, just skilled enough to apply well known math to specific problems for which the general solutions are already known. The prefered math learning strategy for engineers is learn by doing - just overload your brain with math problems until you start seeing the patterns. Society will always need engineers as most people are too lazy to do their own mathematical thinking. Even a failed engineer studied far more math models for reality than the average person will ever get in contact with and can apply those modelling and analytical skills to pretty much any field. You don't have to be particularly smart to be an engineer, although being smart certainly helps; just having an uncanny persistence and a positive attitude towards failure is usually enough. Those who succeed will be able to afford a confortable life for themselves and their wife's children.
Is there any relation between extreme high IQ and mental illness?
pic not related
>>8162603
yeah
The correlation is actually against mental illness
Above average tends to suffer more from mental illness
High IQs like 125+ on the other hand, do not tend to be afflicted with mental issues, including depression
>>8162603
AFAIK schizotypal personality disorder and high IQ correlate.
>>8162684
Same thing with OCD. I think it depends on the disorder. In Schizophrenia for example having a low IQ is another risk factor.
Do we have to prove the existence of every single set we use in mathematics?
>>8162529
The correct, rigorous, formal answer is yes.
However, the real world practice is no. Very few people are actually aware of undefinable sets and those that are actively choose to ignore them because they open a Pandoras box of questions and theorems that make the mathematical community uncomfortable.
>>8162529
anything between { and } is a set, what is this ambiguity you're talking about?
>>8162543
There are so many things wrong with this I don't even know where to begin.
There has been many discussions on how to plan a self-learning course for mathematics; what about statistics? I'm on Wackerly right now, and I was thinking about moving onto a graduate level text after, but I don't know what other supplementary textbooks I should learn from prior to doing so.
>>8162440
Just find a book on whatever interests you most
if you can't self learn how to self learn then you can't self learn
which is why this entire board is a waste of space. even legit threads are pointless.
Does a statistician need to know all of those distributions by heart?
Will pushing my tongue against the roof of my mouth on a near-continuous basis move my maxilla up and forward?

I think I see where you're heading with this.
Why do patients who suffer from a palsy of the biting muscles (like car crash victims) experience a shortening in interpupillary distance?
Can interpupillary distance be widened by strengthening the biting muscles?
I have a two part question for you /sci/, which you probably have been asked before:
1) Is it true that the majority of, or a large number of, people within STEM have some from of high-functioning autistic spectrum disorder?
2) If so, in which fields of STEM is it most common and in which fields of STEM is it least common?
Pure math here. Don't have autism. I would say about 1/5th of my undergrad math cohort had some form of autism. In grad school that dropped to just a few.
I think physics has the most autists because it's theoretical wankery but to them it "has a point". Sperglords can't understand the beauty in math for math's sake.
>>8162164
>high-functioning autistic spectrum disorder?
If this were to be true then that is a misnomer and should be renamed to 'average-functioning and smart but lazy-function autism'
In a classroom of 50 people you would be lucky to find a single one who is even remotely intellectually ahead of the curve, if by the curve you consider the average potato farmer.
You roll a 1 kg ball with no coefficient of friction down three slopes of angles 20, 45, and 75 degrees respectively.
my conjecture is that the x coordinate of the ball increases at the same rate no matter the angle of the slope you roll it down.
discuss.
>>8162003
this isnt homework. i figured it out already but i want to see what /sci/ thinks about the question. i just think its interesting.
Well, after you finish dynamics 101, you can calculate it by yourself.
