/sci/, I'm a little scared right now, though not in pain. The feeling seems to be subsiding.
I had just taken a bite out of some candy bar I never tried before. it might not be related, but now my neck and jaw area feels and sounds as if filled with crushed glass. It's not painful, just the soun and perhaps a slight stiffness.
I'm typing this standing up and the feeling has gone away. What the fag just happened? Allergic reaction?

There's a weird issue me and my friend would like to know the answer of. How fast, and how long would your eye lashes need to be, to actually start flying with them. Let's assume the world operates in super slow motion and you're in usual time to compensate. How fast would you need to blink with your eye lashes (let's call them Eye Bashes Per Second (EBPS)) to start flying? How long do your lashes need to be to create viable flight with the EBPS in question?
This sounds like a troll and we know it's impossible, but humor us with theoreticals.
Maleanon here.
I have long eyelashes and these are the MOST ANNOYING GODDAMN FUCKING SHITS in the world.

Is science and physics becoming lazier?
It seems that way anymore, with concepts like dark matter/dark energy and string theory.
They just seem like attempts at plugging holes in formulas because scientists don't have answers yet. So, they act like these theories are true, and books are written about these ideas as if they're facts and journals treat these ideas as if they're real.
I noticed this with the planet 9 hypothesis in the news. Everyone is acting like there is a ninth planet out there, but it just seems like they were too lazy to...

these plugging holes, are how the real patches get started on
you are right, we dont know what the fuck we are doing, our models are not strong enough
feel free to do better. oh wait, you cant even plug holes because youre retarded armchair scientist undergrad
>>7801843
>our models are not strong enough
You mean our computation power is not strong enough. The sheer complexity of "real life" models makes numerical computation ridiculously time consuming and difficult, so we HAVE to stick with simple models for the time being.
>>7801876
I think op is talking about models made from little /poor data.
No one says that the 9th planet (if thats what it is) is figured out . and any actual scientist will tell you that our current knowledge of anything past the moon that we havmt physically probed and studied is rough oversimplification s at best .
I mean we live on a planet that we know next to nothing (relatively) about.
Its not lazyness people just make hypotheses and try to explain shit .
Creativity is a byproduct of intelligence or is a complete different thing?
>>7801829
>define creativity
>define intelligence
>compare
>>7801829
it's a byproduct of intelligence and a complete different thing, those are not exclusive.
If you are creative, you are intelligent enough to see links where others can't really at first.
But if you're only "textbook" intelligent (forgive me for this expression), maybe you are limited by what you learned by thinking it's the ultimate truth and limitation. You know, the "if it's not already been done then it's stupid" kind of mentality, or the inability to step...

Creativity and intelligence are intrinsically related. Neither are byproducts.

Question: If there were any science experiments you could partake in be it past/present which would you have done?
Bonus: What molecular structure would it take to make a metal such as Marvels: "Adamantium"
I'd love to do some particle or quantum physics experiments. (Too bad that I do chemistry for life, not my field hehe)
>Bonus: What molecular structure would it take to make a metal such as Marvels: "Adamantium"
Uhhhh.... metallic, I'd assume.
I think the picture is wrong. Shouldn't it be rotated CCW?
Does anyone know about studies of frontal lobe activity after eating various flavors. Or how your reaction time differs after eating certain flavors. I am doing my project on this right now.

Every single human is different yet different reactions, wouldn't know your answer.

Shit study to be honest
I have wondered for many years now, will oatmeal digest properly even if i do not chew it much at all? Will i get the same benefits if i just swallow the stuff?
I'm talking normal quick oats with hot water added. Not steel cut or any other kind of oats. Pic unrelated.

All you had to do was not post anime shit... But you fucked it up.

dude who needs definitions

looks like phi is an impossible event.
looks like S is any possible events.
>>7801389
I don't read that book but I know immediately that by S, in this case, he meant [math]\Omega[/math].
[math]P(\Omega) = 1[/math].
Stop being such an ass. If you don't like it, you can just switch to another book. Is it too much to do?
Should start a poly-phasic sleep schedule? Will my life improve? Or will I slowly kill myself?
>>7801232
MEMES! MEMES! ALL TYPES OF MEMES! EVERYONE MUST BELIEVE AT LEAST ONE MEME!
>>7801232
Every study I've seen done on polyphasic sleep cycles showed negative results. Most of the claims about famous people who used them are false/have little supporting evidence.
I'm sure you could get by but sleep is incredibly important and you're better off getting as much as possible
It's too risky. Your body literally cleans toxins produced by the brain as it thinks. These toxins can cause permanent damage if left out too long. Brain cells are cannibalistic. Don't do it or you'll change for the worse.
If an AI in an autonomous droid/warbot is to make "good" decisions in a warzone, for example who's a civilian and who's not, what targets take priority over others, who/what is worth saving/rescuing, and so on, what would be the best way to teach it to make these decisions?
A self-adapting Deep Dream style system that can recognise "innocents" vs. "combatants" by their characteristics? But then what informs that?

what the fuck is that, deep dreaming is a method for making what happens inside a neural net understandable to humans.
I don't know who to turn to/ask. A loved one is a borderline type II diabetic (diet controlled). I've been away from this person for a few years and recently moved back. In these two months, there's been two instances that lasted for around 72 hours each time.
During this time this person was very agitated, unable to be still for any significant amount of time, was sweating even though the temperature was pretty low, fine motor control was shot, was strangely increasedly accommodating (would frequently ask if I needed anything/wanted anything/temperature was...

Please Obi-sci-kenobi. You're my only hope.
I know this is "homework help question", but I really want to learn the method on how to solve matrices.
This is just one of my problems, but I can't seem to solve it with elementary row operations. An online calculator can solve it, but I can't figure it out. Is the system inconsistent?
The last column is obviously the right side of the equation. Everything to the left are obviously the coefficients.

I need a basic answer for a question about R, I'm just starting out
lets say I have a vector of integers called x. Normally, if i try to return certain elements, I can specify x[some range of elements]. What is going on if I try to return x[NA]?
Is this question better suited for /g/?
>>7800716
Are you trying to find NaNs in a vector?
It returns NA over and over again, depending on the number of elements in a vector. I know you can use is.na to NA's. I'm just trying to understand the output of x[NA]
Many diseases related to old age are attributed to damages to mitochondrial DNA that occur during the Oxidative phosphorylation phase of glucose dissimilation. So would a keto diet technically be able to prevent these diseases, since keto means no glucose so no glucose dissimilation to damage the mtDNA.
Right?
No.
There are populations, like Eskimos, that are in Ketosis for their entire life spans. Try to find out if they get the diseases you are worried about.
