can a biology nerd explain hair growth to me. So for years my arm hair has been the same length, like 1.5cm or so.
I recently shaved my arm for a tattoo and 3 weeks later its already grown back almost 1cm. How is this possible if your body doesnt know when the hair has been cut.
Ive tried researching and found out that it grows in stages but it doesnt make sense, someone help
>>9148602
stop being a faggot,it is only hair.
>>9148620
its not the hair, i just dont like when i dont understand how something works
Are you sure you did your measurements right? That's pretty long arm hair.
So how the fuck do I become immortal? No, don't give me that "just take these supplements that don't do shit" bullshit. Seriously, how do I do it?
I hate this board.
>>9148533
cancer is a good example of what happens when your body wants to become immortal
>>9148533
Never been done. We have no examples, so there is no answer.
Realistically speaking, its just not possible. Even if you upload yourself to a computer, modern computer technology wouldn't make you immortal either. The data degrades over time, and so does the hardware. You might buy yourself another hundreds years or two with this impossible technology, but you wouldn't be immortal. Just longer lived.
>this man has compiled a list of 14,245 triangle centers

What the fuck is this?
>>9148481
I´m not really sure what the fuck is this, but why would anyone need to make a list of this in the first place? a triangle center is something of which a formula exist to determine it, therefore compiling a list of them makes as much sense as compiling a list of square roots of a certain quantity of numbers
why?
Other than the brain, what else would occupy the space of a cranium this large? Is it just fluid?

Is it normal that my heart hurts when I lay down to sleep on my side? I have also noticed it sometimes skips a beat and beats strongly, specially after eating sugar or bread.
Should I go to the Doc, or nah?
Doesn't sound nice, go to doctor
Could just be indigestion/heartburn?
>>9148554
I don't think so, it feels like the pain goes along the beating of my heart. I have also noticed my BPM takes a long time to go back to normal after exercise
How do I come to terms with the fact that males will always have superior logical and analytical skills, and that female achievements will never, ever, compare in the field of science and maths?
I can work my ass off and beat other females in my class but I will never be the top of my class.
just b urself

Whatever you do, don't become a blue haired feminist with chewbaka-tier hair levels all over your body that eats her own period just to offend males.

any ideas? :\
>>9148355
Control engineering is EE
You've just fucked up in general anon
You could do a project about self calibration. For example if you place sensors on a robot and design a control system that depends on the exact location of the sensors you will end up with an offset if the positions are wrong. You can design a system to determine this offset.
Could work on an HVAC system for a greenhouse.
Make a machine that makes mixed drinks or some kind of food.
Buy a drone and then create a control system to control its movement for: package delivery, two drones working together for coverage/surveillance, etc.
There is many more things I could suggest but it really depends on your experience with controls and building things
you should build a bike... and run away

Why is it so hard to solve this simple problem?

look into it

Set n to be one. Problem solved.
There is more to it than meets the eye.
Obvs you think it looks easy with that HS algebraic knowledge
I've got an exam in 2 days. I need to repeat everything, or as much as I can, in those two days. What is the most effective way to organise my sleep in 2 days to get the maximum out of my studying, regardless of the consequences it'll have on me later?
The subject is microbiology if it matters.
>>9148214
Forget about sleep. If you haven't revised until now you should be doing all nighters.

Does anyone know anything about how certain genetic traits are transferred? I'm curious to see if/how I can have a blonde-haired, blue-eyed kid.
>Mother is 100% Bulgarian, DNA test shows strong link to Finland, Netherlands and White Russia on her side
>She has light brown hair, green eyes and very pale skin, her sister has blonde/blue
>Father is 100% Spanish from northern Spain, he has black hair and normal white skin with light brown eyes, his sister has very pale skin and green eyes
>I have moderately pale skin, brown hair and light brown eyes
Share your stories on how your genes were transferred to you desu

Jesus christ, I'm nowhere near a pollack but this is just fucking abysmal reporting. More than that, they're openly taking the position of being against free speech and open exchange of dialogue and ideas. How did scientific reporting fall so low?

/sci/ is blind to the subversion because they are part of the problem. Academic science is not science. It's institutionalised political corruption.

After being on the internet for over 20 years I have found one thing to be true. All those old book and magazine articles are nothing more than a bunch of blogs. When you go back and read stuff with that in mind, it makes a lot more sense and is a bit depressing. Of course pure fiction and things like encyclopedias and completely pure tech stuff doesn't fall into that problem, but literally everything else does.
Fast forward to today's books and magazines and it is far worse because they are competing with the internet and the people writing things either grew up with it or have been on it for so long it completely warps their mind towards it. The only good advice I can recommend you is to stop reading this shit. Only read the meat of things. Meaning read Nature only for knowing what is new then looking up the papers for that study. Don't read anyone's opinion on studies unless you know them in person. It isn't worth it otherwise.
>>9148127
Yeah, you even have to watch out for which papers are in the news because those are either specifically created to move a propaganda along or selected to do so.
>>9148136
Yeah, I ain't buying this shit anymore. Its the same with the Economist. I just want summaries of papers and upcoming developments, not some retarded journo's hamfisted opinions. Waste of a fiver.

Is social science a degree based on facts or feelings or both?
I get the impression that social science is full of hippies.
It used to be pretty fun until people started getting upset. Nowadays STEM is the only real option
>>9147943
Facts, but professors will almost always be biased toward feels.
Notice social sciences are such in demand but society onlt becomes less stable and people are more distrusting and divisive as ever.
That said I liked social sciences in college as well as economics. Both very soft sciences that are unreliable when applied in real life.
>>9147943
>both
this but mostly feelings
