Well /sci/, what is it? A real illness? Any personal experiences with it? Theories on causes?
pic unrelated
in my case lack of sleep causes it
think different people have different triggers
my theory is everyone has a down mode but some people manage to avoid triggering it
nothing to do with 'chemical balance in the brain' or any of that junk

>Any personal experiences with it?
Yep. I've been depressed for about a decade, I started exercising and going to the gym about a year ago and I honestly can't remember feeling better. Since then I've been wondering if there's some link between the increasingly sedentary lifestyles of people and the raise in the prevalence of depression.
A natural response to the inhuman capitalistic system that we live in
The Erdős–Straus conjecture states that for all [math]n > 2[/math], there exists [math]x, y, z \in \mathbb{N}[/math] such that [math]\frac{4}{n} = \frac{1}{x} + \frac{1}{y} + \frac{1}{z}[/math].

Anyone here know about head injuries?
I seem to have some sort of internal head injury, acquired five months ago from whiplash. It's on the right side of the back of my brain and hurts whenever my neck muscles are flexed. Typing this right now is causing it to hurt. I am unable to go to a doctor because of other circumstances.
I just don't know what to do. First of all, I can't sleep for more than, usually, 6 hours in a row because of my noisy family. And I'm having trouble napping because this head injury is making my hallucinate. I'm gonna start...

Do you have a fever? You might have meningitis. I got bird flu and then got it this year, thought I was going insane.
Just try to excersize, eat right, and get some anti-biotics. The hallucinations will stop once the fever starts going down.
You can get fish anti-biotics from the pet store btw, it's the same shit. Just google the dosage. Take them for 2 months.
So lets say you build a flying colony on venus 55 km above the surface and you fall off, how do you die? Assume you are wearing a special acid resistant space suit and have been breathing heliox. Does the wind force kill you before the pressure kills you? Or do you survive the pressure long enough for the heat to cook you?
And just for fun, if you are wearing a magic 150 kg pressure suit, could you survive impact?
>solid panels on venus
What would be the point of that lol
A rigid is probably the way to go, not this suspended balloon.
>>8107178
Solar intensity is more than twice that of Earth, plus the clouds are so shiny that you can put solar panels facing down too.
This thread is not about colonizing venus, it's about dying on venus.
you would fall quite a bit slower than on Earth, and the space suit would protect you from heat, but the landing would be too powerful to survive.
Can we please discuss why the Soviets (at the time) have pictures of the surface of Venus but NASA is jacking off to the same old pictures the Curiosity sends?
>>8104704
Because the soviets made an effort to land probes on venus after accidentally doing it once, while NASA made an effort to land literally everywhere else
>>8104704
the most reasonable answer would be costs: the Venera landers only survived a very brief time on the surface to send back a few pictures. The hazardous pressure down there is probably going to brake today's equipment as well. So the costs do not justify the means. Also, Mars is much more interesting from a long-term perspective. What are we going to do with Venus? Attempt to land Mark Whatey there?
But I agree that this one pic we have from Venus is making me quite emotional. In my view, having been to...

Weak Western robots are too homosexual to land on Venus
So we all know the high school textbook explanation of lift is incorrect. It explains that air molecules traveling over a cambered airfoil must travel faster over the top, a larger distance, in order to "meet up" with the molecules traveling along the bottom. This is wrong, as there is no physical principle or rule that necessitates that the molecules must "meet up." Amazing how often this myth is still perpetuated.
Anyway, I know that lift is predominately the result of angle of attack, in accordance with Newton's 3rd law. This is the reason...

Number conservation. If the rate in > rate out the fluid bunches up.

To my knowledge, this is exactly what happens and results in a wake of turbulence and vortices. Can't remember where I saw it, but there was a nice .gif showing the molecules of air flowing along an airfoil and demonstrating that the air on top does indeed reach the trailing edge before the air on the bottom.
Found it.
>set theory gives math a solid foundation
>if you combine the two-element set {1,2} with the two-element set {2,3} you get the three-element set {1,2,3}
Set theory is categorically retarded.
>>8106186
You can see it anohter way, instead of elements look at what the sets they contain.
Any set contains the empty set and itself.
Therefore, the empty set contains the empty set and the empty set. So it only has one part, the empty set.
Now the set {empty set} will contain the empty set, and the set that contains the empty set.
Basically, the parts of {empty set} are empty set and {empty set}, those are two parts.
And that makes sense when you think about it.
So a man with a container...

hello wildberger
Please, please tell me no one on /sci/ actually fell for the "0.999999... = 1" meme.
>>8109416
Well, prove that it isn't.
Show that if you assume 0.9999... = 1 then that leads to a contradiction somewhere.
pro tip: Make sure your argument does not have contradictions itself.
>>8109440
>hurr you have to prove a negative so that I dont have to prove a positive durrrr
Fuck you. You support the claim, burden of proof is on you.
>>8109446
>burden of proof is on you.
It used to be. Then people came up with a billion proofs for the proposition.
Now that we have a proof that works, the burden of proof is on you as you are now trying to dismiss a well established claim.
Faggot.
Go ahead, this should be easy. Just type up one single number that is between 0.999... and 1.
If there is even one then that would immediately imply that 0.999... is not 1 so go on.
Type it up faggot.
4chan is illogical.
Nothing "learned" here is retained.
This is a waste of time, a haven for the mentally ill.

Part of it is the fact that I reflexively start shitposting on 4chan whenever I feel stressed or frustrated, and part of it is the fact that this idiotic website provides me with a sense of meaning and belonging I can't find in the real world.

Has there ever been an issue that 99% of scientists agreed on, and then we found out that it was just politically motivated and the scientists were wrong or lied?
I mean, with the state of affairs now regarding climate change, there are many people who insist that it's all a lie. But has a lie on this scale ever leaked through the scientific community before? I'm genuinely curious.
P.S. Why the captcha take 60 seconds to do now

The biggest one i can think of is earth being the center of the universe. The church was powerful and to have any sort of career or influence you had to follow the church's way. Most people are followers and don't want to rock the status quo.
I think climate change is somewhat similar. You have 99% who will agree to whatever their funders believe (government) because it puts food on the table. I think the recent discrepencies in the actual data and models showing the warming isn't as severe and perhaps the feedback mechanisms are stronger than thought puts funding at risk for so many people that they are just doing what any would do if they were at risk of losing their job.

GMOs and vaccines being safe.
>>8097524
There hasn't, I'm guessing because the scientists and politics motivating it are too powerful to fail.
There was a thing called climate gate a while back, but it turned out to be a lie fabricated by environmentalists. Basically an environmentalist targeted the Cato institute (often targeted because they assert opinions that go against the mainstream i.e. Supporting smoking and denying climate change) and made it look like they were trying to hide information, but they actually weren't. Doesn't...

What is the most exciting field in CS?

It's not a field per se, but if you include computer engineering FPGAs are really fascinating to work on, if a bit frustrating.

Creating exotic dildos for you mom.
I'm coming clean right off the start by admitting this is my first time on this board. I will also admit that I am a pretty [spoiler]dumb[/spoiler] average 23 yrs old with no special school feats (barely passed weak maths in hs), limited science knowledge (what are physics) but I do have the utmost admiration for creative minds (sci-fi writers, visual artists, vidyas, etc.).
So what the fuck am I doing here? Well, I'm tired of being stupid.
