>I fell for the Noopept meme
I kept seeing great stuff on here and reddit about it, so I decided to order 5g from a reputable supplier. I just measured out 10mg and poured it under my tongue and held it for 10 min. It didn't dissolve very well. I washed the rest down with a glass of milk.
I definitely don't feel sharper or smarter at all. In fact, I feel more retarded for falling for the Nootropics meme.

Just believe in it until the placebo effect kicks in :^)
>>7983782
Just use caffeine
Isn't it supposed to be a gradually manifesting effect? Don't be hasty.
Do you think they'll ever catch up to piston engines before ICE becomes replaced with electric altogether?
Mazda recently patented a new design, see >>>/o/14781432
>>7983758
What's a rotary engine and why should I care?
>>7983763
Wankel engine.
>>7983758
>ICE
>Ever being replaced with electric
Tesla shill pls go. Also Mazda is the only company that has ever believed in the Wankel. Despite achieving great things no-one else can be bothered to retool. this is why the Wankel has failed to make an impact, the industry is simply too set in it's ways.

>Wankel engine.
In japan its called a wanker engine.
Not sure where else to post this, I figure there might be a few medical professionals on this board. This isn't serious enough to actually go bug a doctor down at the clinic so I figured I'd ask you guys.
The outside of my right thigh is numb. Like, not the kind of numb you get when your arm falls asleep or something. It's the kind of numb you feel when your skin gets really, really cold or something. It's been like this for a few hours now. I've tried stretching it and massaging it to push blood around, and I've tried applying a hot wet rag to it to heat it up. Didn't help much.
At first I thought it was just because I was sitting down practicing my classical guitar for so long (the position can sometimes put your leg in a weird position). But like I said it's been about 2 hours now since I stopped doing that and nothing.
>tl;dr
My leg has been numb for a few hours now despite my best efforts to correct it. Am I about to have a massive stroke or something?
You should probably go to the emergency room. If not,take the largest safe dose of aspirn you can and try to move around as little as possible while laying flat.
>>7983590
Emergency room? This hardly seems like that big of an issue. I am a 20 year old man, a little overweight but nowhere near the point where my arteries are plugged up with grease and cholesterol or anything. I can't see how it could be anything very serious.
>>7983583
I'd cut it off if I were you.
It sounds like your symbic nerve has been caught between your trachin and quinia. If that persists there's a very large chance that the electric pulses from your spine that are being blocked by the trappage will enter straight through your groin.
I've seen this happen before and it's very messy.
Don't try to drive to the hospital - it will only make it worse. Self amputation is the only option. Make sure you have aspirin lined up.
What is the best way for a noob to learn precalculus?

How does opening a book teach you precalculus? I've opened books in kindergarten but I didn't learn anything.
Out of curiousity, how does the naming scheme for medicines? Sorry if this is the wrong place for this question, but I'm writing a story in a near future where a new ADHD medicine is developed that causes a drastic increase in the creativity of the person taking it.
I don't know much about neurochemistry or pharmaceutical manufacturing but I assume that this hypothetical medicine would be in the amphetamine family but I'm not sure if it would have some sort of prefix in the clinical name (dextroamphetamine etc).
tl;dr: How could a drug that boosts creativity work and what would the clinical name for it be?
>>7983439
Brainicillin.
It's random
>>7983440
That would be an antibiotic wouldn't it?
>>7983439
The people who discover it come up with a name for the base structure that's significantly shorter than the IUPAC name. Everyone knows that that structure refers to the substance of that IUPAC name. Prefixes are added to indicate modifications to that structure.
Since you mentioned amphetamine, amphetamine's chemical name is 1-Phenyl-2-propanamine. Methylated, it is (2S)-N-Methyl-1-phenyl-2-propanamine. Scientists know amphetamine refers to the first, so you stick a "meth" before it to indicate the methyl group.
It's for convenience and not to confuse doctors.

Why study mathematics or physics at university when you can study engineering and get a job? Then you can study maths and physics in your own time to your hearts content.
t.this is what I'm doing.
>>7983284
Because for some people:
Chance to do physics research > Engineering jobs
"can" is relative.
The fact that so view (I can only think of Heaviside) do it makes me thing it's not really a path you are eventually willing to go.
If people start working, get families etc., they are lost w.r.t. doing something relevant.
And I don't personally know any engineer who's good at math

Am.. am I going to die bros?
>>7983278
you should probably go to a doctor and ask them.
Also you should probably ask that doctor about working out regularly so you don't die.
Its not that hard to figure out.
Yes. But don't feel bad about it, even /fit/ people will die eventually.
>>7983279
I second this.
Also learn to play the violin. You have an unfair advantage. See Paganini.
With ordinary fitness, ordinary lifestyle and lots of humour you should have good odds of reaching 80. The only common factor they have found for the very oldest people is a strong sense of humour.
Need help with this math question, I understand what to do but not how to do it. Could you show me the steps?
y = 2x^3 - 9x^2 + 12x is drawn, calculate the area within the dotted region.
I know I need to intergrate it from 0 to 2, but how?
Look at the primitive of ax^b and do it three times.

Where can I purchase a small sphere of aerogel like pic related? Carbon or Silica is fine.
Also, I'm curious about its properties irl, since I've never handled it and I would like to keep it and handle it frequently.
>How cleanable is it?
>How elastic/firm is it? I've read that carbon is pretty elastic. What about silica?
>How light is silica aerogel? Apparently carbon is insanely light and won't deform flowers it sits on, but I can't find images of silica on anything but people's hands.
>>7983095
You can buy plates of it, but a sphere is not something that they would make since it makes no useful sense.
>>7983111
What good are little cylinders? They're basically all just curiosities and specimens for ogling.
>>7983111
Also, I got this image from someone that was selling them on Amazon, but is out of them. So someone made some.
Usually Penicillium molds are used to preserve meats like salami.
I'm wondering if I can use Psilocybin mold instead.
I've got no idea if the actual penicillin content of the mold plays a part in preserving the meats from bacteria...
And I think it would be kinda cool to grow magic mushrooms on salami before you eat the meat.
What's /sci/s advice?
>>7983070
enjoy your food poisoning. It will probably not work because psilocybin is very fragile and will die on almost all encounters with other funghi or other micro organisms. So I don't see this working. It's probably easier to just slice up your shrooms mix them through the meat then dry conventionally and eat it.
>>7983086
:(
Well that just ruins a food fantasy.
If you didn't know, until a certain age, the mycelium of psilocybin can be out grown and killed by other organisms, even bacteria. As well, if the medium its grown on is too dense, it will never grow to bloom mushrooms, so it will produce very minimal psylocibin.
WTF? Are they expecting me to know the molar mass of carbon dioxide off the top of my head?
the ideal gas law is PV = nRT, with n being the number of moles. How am I supposed to know what n is without memorising the molar mass of carbon dioxide?
>>7982949
carbon and oxygen masses are two of the easiest to remember and also two of the most commonly used
they're 12 and 16 and im not even a fucking chem student
>>/wsr/

I'm a physics student, so I didn't think I needed to know this shit.
What else do I need to memorise from the periodic table?

Is it possible to turn your life around after a bad Undergrad?
It would be extremely stressful
>>7982638
For you
>>7982636
Nope. It's over. As /sci/ will tell you, if you didn't complete your undergrad with perfect grades at age 13, it's over.
I've been looking at this function
[math]f(x)=x^x[/math]
and I cannot obtain its derivative.
I have tried re-writing it as
[math]f(x)=(e^x)^{ \ln x}[/math]
but that doesn't seem to help.
wat do
It looks to me like you would get it from u-sub.
I'm sure someone on google has gone through the steps though.
