Is there anything worse than learning a useless set of skills with no practical application and that will serve no purpose once you are dead?

What does, brainlet?

How come the velocity of the wind speed in a wind tunnel drops as AoA on a simple is increased?
Could a restriction be caused by aerofoil acting as a crude butterfly valve, or does increasing turbulence of the flow interacting with the boundary layers of the aerofoil and tunnel walls cause the velocity to drop?
Conservation of momentum suggests that the velocity should increase instead of drop.
Any ideas?
*on a simple aerofoil
Are you talking about the actual inlet flow from the fans, or are you looking at airflow after it's passed the model?
If you're measuring outflow, then yes increased flow separation with angle of attack would probably have some effects on your airspeed.
The wind tunnel I've worked with tares out wall effects. If this is data you've pulled from somewhere like NASA or a decent tunnel, then wall effects probably aren't the cause. If you're working with babbys first wind tunnel, then yeah maybe. Either way you're not giving a lot of details here.
>>8541549
the increase in AoA blocks the air flow, making it harder to travel inside the wind tunnel
then, you need more force to make the air travel at the same speed.
talking about momentum, more energy from the air flow is transferred to the aerofoil with higher AoA, then less energy for the air
Biofag here. What are some good books/resources for learning about LTI systems, control theory and transfer functions?
I want to make simulations and mathematical models of physiological systems.

If you (as a mathematician) don't have a thorough knowledge of set theory and logic you're no different than a code monkey.

Could someone explain to me what a brainlet is? I've never been on this board but i have a love for science and math. Pic unrelated.
>>8539919
Someone with average of below average intelligence
And holy shit, how many years since the last time i saw pedobear
>>8539919
A brainlet is someone who hasn't at least read these books.
>>8539919
someone with slightly above average intelligence but overestimates their own worth
anyone who boasts
someone who gets mad at others when they dont understand something
someone who is always insulting other people's intelligence
someone who is more interested in winning an argument or seeming informed than being factually accurate
basically doing anything that smart people tend or at least strive not to do
Ok /sci/ let's have some fun.
Is there a point where it becomes ignorant to continue asking why? I don't mean like stupid stuff that can be Google'd. I mean something like in quantum physics or whatever.
Like gravitational waves, for instance. Right now we're looking for waves, then we'll look for where they come from, then we'll look for why they come from there, then we'll look for what causes the process that causes the process of the formation of gravitational waves, and so on.
When does it become ignorant to keep going? Is there a limit?
Sorry if that was a bad example, but I hope it gets my point across.
>>8539787
never. all knowledge is useful to extend and help enjoy your life
>>8539787
I think the limit is when the answers doesn't add anything to science(I.e can't make predictions, can't be verified by experiments, etc)
Depends if it's in an argument or just for your own contemplation
I'd say it's impolite to discount people's ideas about one strata of whyness by trying to go deeper with another why if it's not warranted
It can also drive yourself to nihilism if you do it internally too much. At the core though the issue is an important one since you're really trying to get at the underlying basis of reality, it's just you have to do it in steps and can't dig too hard for answers that won't come
in which they contributed alot to science?
Muslims had their golden age
Europe was the dominant sceintific continent from like the 1500s and up
what about Africa
>>8539498
Which part of Africa, it happens to be a very big place, with very different cultures and ethnicities?

he was brilliant, but has no accomplishments...
i mean is he really on the same level as someone like Einstein

Is it too late for a 25 year old who only got up to calc1 to learn enough to make a living in chasing the commercial fission dream?
Separately, if all I know is highschool level physics, chemistry and calculus, what do I need to start learning to have a comprehensive understanding of fission reactors? are there papers and diagrams and stuff that are public?
>at a bar
>So what do you do?
>me and a bunch of guys are trying to build a star inside a bunch of magnets. mite b cool.
>25 years old
>only high school education
>wants to develop cold fission
>primary motivation is to pick up girls at a bar
I'd just give up now.

Fission? I think you meant fusion. Commercial fission is a reality.
been reading security engineering by ross anderson, wanted to know whats a solid way to start applying the theory? (sites, projects, shit to hack, etc)
>>8538751
Bump, I am in the same boat. Though, white hat, of course, all legal.
>>8538751
quickly browsed through a couple of chapters, it looks to me like there's nearly no substance to any of the topics here
so my suggestion is to pick one of the chapters that most interested you and then go and buy a book about that
>>8538765
>Interested in hacking.
>Buying a book.
>Buying in 2016.
Riiiiiiight.
why does thinking about math hurt my brain? surely it gets easier right?
also how do you become a researcher that doesn't do teaching meme bullshit?
>>8538160
what do you call teaching meme bullshit ?
also cute frog tbqh
>>8538160
Brainlet, git gud
No if you're such a brainlet, you aren't even close to get into research, seriously
>>8538160
No, it only gets harder.
Not many places do pure math research outside academia. You could go to the NSA though and not teach.
>final grades posted today
>B in Calc I
>Not even B+
How am I gonna cope? Am I a normie?
Am I going to make it?
I got a B in calc 1.
Now I am a street whore.

lol
>>8536980
Fuck off OP, my situation is worse. I got a 5 on the AP calc, but had to drop calc 2 because I was gonna get a C or D. I might as well print out that "W" in red and staple it to the back of my shirt because it's never fucking going away.
>needing a calculator

If I colonized my guts with oxygen producing bacteria would I be able to live underwater because I wouldn't need lungs?
Intestinal tract has a larger contact area than lungs as well.
Your like go would have to fill with something breh. You would need a tube going from your asshole to your mouth so you could breathe your oxygen rich farts. Only then could you survive.
