It's been 14 years since 4chan /sci/ posters solved a math open problem. Why has it been so long? What changed since 2011 that made 4chan users unable to solve math problems?We need to go back
Different demographic, 4chan is not 4chan
>>16871863I mean, we trained sand to do maths.Training a bunch of faggots to do the same couldn't be any harder than that.
>>16871863Go back and read threads from that era. There was some better top end content but most of it was just as worthless as what's discussed now. And /sci/ never touched the quality of the Space Elevator threads on /pol/. At least the "Why did he do it?" threads have stopped. Too bad the "Does 1 really equal 0.999..." threads are still common.

>>16871863Back then, 4chan wasn't a p*rn*graphic jesspit.
The concept of terminal velocity makes no sense to me
>>16872848drag force is a square of velocitygravitational force is practically a constantat some point drag force = gravitational pull force and velocity stops increasing

>>16873659Materialism post. Empirical testing has no value in measuring the validity of a mathematical concept.

Interested in seeing how posters on this board score in comparison to /x/, where the overwhelming majority seem to be schizoid sadists or complete autists living in internal fantasy lands:>The CIA uses the PAS for the assessment of characters, its self-assessment online form has 64 outcomes and doesn't sugarcoat anything, if you have bad luck, the test will call you out for being schizophrenic, a recluse, or worse.https://www.pasf.org/pasq/index.htm>To get your type among the 64, take the 'primitive' test first and then type your results into the 'basic' test and take that.The primitive personality type determines your core personality that you developed as a child, while the second test determines whether you outgrew that core personality to adapt well to society, or whether you indulged those core behaviours to become psychologically maladaptive or attain some kind of arrested development.It really does not pull any punches; while an MBTI test will only tell you positive personality traits and leave you to infer the negative, this one is the opposite. Depending on how you score, it will tell you that you're an exceedingly mediocre well-behaved citizen (one of the best endings) or have the profile of a serial killer, autistic shut-in or concentration camp guard.

>IRU>Autisticgreat...
>>16872873>Initially, he is in danger of becoming so autistic and nonresponsive that he risks never making contact with reality. >it is very difficult for the [IFU] to cover his schizoid activity Holy shit WTF!
>>16873309>Its all bullshit but atleast its funI don't think these tests are bullshit per se.The bullshit part is that you are the one answering questions about yourself, and the vast majority lack self-awareness.It would be far more accurate if others answered the questions for you.
>>16873091>Usually, he tries to be as conventional and conforming as possible to any milieu in which he finds succor and security.
If so, why is that?
>>16873352Back then there was a lot more open space. You go to the north because as a young adult you go where you do. Then winter comes and if you aren't already prepared you literally freeze to death.With modern technology a lot of those pressures are letting up but that's just how it was.
All available data and every persons personal life experience both show that different races have different average IQs, but a lot of people would really prefer if it wasn't true, so there are tons of excuses people have made up to handwave away the reality of the situation. People really don't want it to be true because the fact is often abused by bad actors and it's the sort of thing that just by knowing it causes people to act like assholes
>>16873508>that different races have different average IQsIQ scores fall apart as metric when comparing massive populations. I was and still is mainly used in the education system where it actually is relevant there.
>>16873281>It filtered people who did not have an aptitude for planning and resource management.Mediterranean.
>>16873255>Whites have built it, blacks did not.Africans did have their own civilisation and states. Pretty much everywhere but the most isolated areas had staye formations and the development of hierarchies.
>In recent years, technological development of nuclear fusion power generation, also known as the "energy of dreams," has been accelerating both domestically and internationally.>In Japan, the industry is excited by the arrival of Prime Minister Sanae Takaichi, who has been promoting the development. The government has set an ambitious goal of "demonstrating power generation in the 2030s."mainichi.jp/articles/20251114/k00/00m/020/299000c
>>16870837>hyperfocusing on immigration and not the sheer 30 year long stagflation, wages being among the worst in the OECD, loss of economic niche and prowess.Dumbass
>>16873032no one cares about low wages in japan because everything is cheap, this isn't goymerica where you work a 100k job but can't afford housing
>>16870727Because it's an endless loop of short term investment that gets pulled before maturation. Basically artificially delaying research, hence why the actual successes have been from state funded ventures which are trudging along as a slow but steady pace.
why do smart people keep falling for this?
>>16873102>no one cares about low wages in japan because everything is cheapNot really. Prices have gone up, professionals salaries are way behind their economic peers outside Japan. Entry level jobs pay jackshit compared to gow ot was decades ago.
grab your calculator, now type 5318008 turn the calculator and look at the number again (yea I'm kinda special)
i can't see the number anymore, i just see the back of my calculator
>>16873640Have you noticed, the bus is getting shorter every year?
>ODE classpretty easy, first and second order linear was a breeze, power series solutions was a little hard at first but I got the hang of it, Laplace was easy too>PDE classwhat the fuck, this feels like a graduate class disguised as an undergrad class, the jump in difficulty is huge

>scientists still can't decide if eggs are bad for cholesteroluseless
>>16872299cholesterol is a macro phenomenon.Every doctor and scientist you have ever met in you life is a complete idiot. Yes, even the researchers. Cholesterol contains far range signalling proteins, which they are encapsulating. You shouldn't be taking anything that fucks with cholesterol.
>>16872530What? they have me on rosuvostatin
ive been eating 4 eggs everyday for at least 6 months, and my HDL went up from 67mg/dL to 73 mg/dL. My LDL also went up from 124 to 149mg/dL.Overall cholesterol is up from 200 to 229mg/dL
This is actually an important question to answer because cows cause a lot of environmental problems and people really should be reducing its consumption and adding an egg to the plate instead.An egg added to a meal should be more common, whether it’s beef, chicken or fish.
>>16873499I add egg to everything. Cheap, healthy and always enrichens the meal. Win win.
Eurofag here learning mathematics on my own, on 6th grade geometry now. My question is, since I'm learning on my own, sometimes I need feedback on the work I've done to know I've solved/worked properly, where should I look for it? Should I just look for a tutor? AI? Here? Let me know.
After you have solved a problem, look at the official solution and compare.
theres no substitute to a ruthless professor and competition with peers.
>>16873285Khan Academy is good for self assessment. KA has interactive exercises that offer immediate, specific feedback. There's no problem if you skip their videos and use your textbooks. You will learn to use textbooks better if KA exercises force you to do so
The vast majority of my professors suck and so do their lectures. I've learned almost everything on my own from textbooks. I should agree with>>16873315At an early stage I grew lazy because I didn't feel challenged. When I went to study for one semester in a bigger university as a exchange student, I find myself really motivated and productive after encountering with many other people who were seriously committed in their education and I could compete with (in a healthy way, of course). Later, I could get a good source of feedback and support from math communities (those which are willing to help you and are not a mere circlejerk). You could find those communities on Discord, Reddit and Telegram. I encourage you to look for them.
Thank you everyone for you feedback, you're very nice. <3
How has he affected your view of chemistry?
>>16868210/sci/ virgins will call him pop-sci
>>16868210>Early lifeHow did I know it before even looking it uo?
>>16872867I wasn't expecting it
You guys are all smelly liars
>>16868327the story isn't on the internet, so its probably false.if so we've got a lot of double digit retards on /sci/ who'll believe anything OP writes
“Alien life exists elsewhere. The odds are just too good.”“But alien life visiting us? No. Impossible. It could never happen.”Are scientists just retarded?. “No you can’t come here. We’re off limits. No way no how. Cope.”It’s fucking weird. Do scientists not consider successor theories to our own limitations? Do they think our limitations are everyone else’s limitations?
>>16872401>Do you realize it’s hard as fuck to travel within spaceFor us
>>16872429If we assume the speed of light is a limit it is hard for everyone. If not then we would expect to have visits, but we don't. More evidence of it being the limit.
>>16869306>it's extremely unlikely.Assuming we're a roughly typical example of life rather than some extremely extremely extreme outlier, I don't think it's unlikely aliens much more advanced than us exist and know about us, or at least about life on earth. What is unlikely is that we'd know about an advanced probe sitting somewhere in the solar system monitoring.
>>16872488You’re still going by our limited understanding of things and not some hypothetical successor theory that transcends our own science

What are great Christmas presents for family in /sci/?
>>16871352Books
>>16871352good boots for hiking imo
>>16872616I've bought my brother books for a couple years, but he hasn't read any because of his school workload.>>16872622Great suggestion; I already bought him a pair of steel-toed ones that can be used in the shop last year.

I read it and I still don't get it. Do we have time travel or not?
>>16871556Special relativity has busted time 100 years ago. Let c>0 and Q(x,y,z,t):= c^2t^2 -x^2 - y^2 - z^2. SR (the first two pages of any SR manual) says: if any two observers are in inertial motion with respect to each others and if they witness two events A and B occurring at dates t_A and t_B, at locations having coordinates (x_A,y_A,z_A) and (x_B, y_B, z_B) respectively, then the quantity Q((x_A - x_B), (y_A - y_B), z_A - z_B, t_A - t_B) has the *same value* for the two observers. This instantly destroy time (apart proper time which applies to single objects only) since for any real number u the hypersurface P_u:= {(x,y,z,t) | t = u} of "events occuring at time u" becomes dependent of the observer (changing the reference frame changes even its direction, making it de facto fictional). The so-called "Andromeda paradox" is nothing but that fact at large scales.
>>16871556To travel through time, one must understand what it is and how it functions.Humans understanding of time changes as we discover more about our universe. Currently sciences models of the universe (quantum mechanics) state that time is an independent factor from space. The problem with most time travel examples is they use loopholes in mathematical principles to try and justify the possibility. As science changes, so to do the hypothesis's. Ultimately the only way to travel through time that is verifiable via the scientific method is going from the past into the future. >>16871588>It's a man made conceptNo and yes. Time is a clear force on our universe humans have observed. With or without humanity time will still exist. The perception of an object is not the object itself.
>>16871588Bravo, Anon.Hey everyone look, the greatest thinker from >>>/lit/ has visited us lmao
>>16871556basically it is a very cool rewind tape, not much to do with time
>>16871556it's actually pretty sad how bullshit this isthey used a "meta material" as a delay line material, but they did an inverted delay. seemingly its more solid state than just an analog delay, but they had to use so much control logic to pull this off that I really doubt this is any better than a programmed DSP which can literally do the exact same function
