Does snorting Melatonin (Insufflating) deliver more to your brain than just taking it orally?
I've done it a few times, and it burns like hell; I wouldn't recommend doing it. I just want to know if it actually does make me sleep better than taking it normally.
Check the bio availability of it insinuated vs oral investment. see which has the bigger bang for it's buck

Is autism an inherently genetic disorder or can it be aquired trough one's lifetime?
genetic
you aren't autistic anon if you were you wouldn't have the social grace to ask
Probably mostly genetic. Some studies have some correlation with outside factors like early childhood and upbringing, but nothing is conclusive. It defiantly can't develop later in life.
if it's genetic than how did it start?
Taking an accuplacer in a few weeks, haven't been in a classroom in a few years. What books/tools can I use to refresh myself in math?

Thanks, man.
Is this everything for basic college math?

You could take the word "non-zero" out of every sentence in which it is used and it wouldn't have any affect on the meaning.

I just finished a multivariable calculus course and went to check my final.
This is one of the problems I got wrong.
Does anyone know how to graph this properly?
>>8048474
It's a degenerate hyperbola
x^2 = y^2
=>
± x= ± y
That's both lines
>>8048488
Sorry, should really change
± x= ± y
into
x = ± y.
Same thing.
>>8048474
are you talking about the function [math]f(x,y)=cos(1/(y^{2}-x^{2}))[/math] ?
be more specific
Do you think the Collat's conjecture is true /sci/?
what do you mean by true? It works, but it hasn't been proven or solved yet
>>8048464
Do you believe it is true?
>>8048467
Its probably true
Can aeromodelling be considered science?
It's an applied use of several branches of science.

I am sure she developed it in her room, not in space.

Hey /sci/,
If (for example) string/QFT are some of the forefront most advanced forms of physics being researched at the moment,
What is the most advanced/difficult/theoretical form of chemistry being researched?
consciousness :v)
nice dimethyltryptamine, fgt
>>8048027
it's not DMT though, b/c that's a dihydroindole in the pic
>>8048484
Uh, no?
Greetings, /sci/.
I am confident to have made a most relevant discovery in the field of chemistry/physics.
I would like to share it with the scientific community.
How to write a scientific paper, thesis, etc, so it can be published in a big magazine like Nature? Who do I contact, how to make sure people will not steal my idea, how to spread the word to as much people as possible, etc?
For the purpose of credit I will not share any detailed information about the contents of the discovery itself.
>>8047864
you made an important discovery by yourself, isolated, with no supervision?
talk to your professors. you don't know professors in the field? then that's a huge red flag, 100% chance you didn't discover shit
>>8047870
>talk to your professors. you don't know professors in the field? then that's a huge red flag, 100% chance you didn't discover shit
ignore this elitist anon
publish your work however you can, usually conferences are easier than journals
you do NOT need an academic institution behind you, plenty of research is done by private sector companies and individuals working for them
>>8047907
>elitist
dude. if he has no education on the subject, and doesn't have a lab or know people who do, how the fuck would he make a breakthrough in chem / physics?
you're really giving him too much credit, waaaay too much.
Hi, I don't know if this is the appropiate place to talk about it I will go on another thread, does anybody know how a robot moves on a metallic strip or/and tape?
This thread is cancer, badly written and I am a faggot

Google line follower robot, it's a great beginer robotics project.
Here is an example of how to make one
instructables.com/id/Line-Follower-Robot/
Basically the robot has a strip of color sensors on it's front and tries to turn such that the black is in the middle.

I want to get a german one, not an italian one, because german shit is low price/well engineered and italian shit is high price/high aesthetic/ poorly engineered. I drink about 12 expresso shots a day and i want a good machine that will pound them out. Is krups german? I cant seem to find which makers are german and which are itrashian
