Is playing chess actually beneficial apart from improving your ability to play chess?I have read/heard conflicting ideas about this.What does /sci/ think?
Does not get you sharper in any way, but allows to find decent friends. Chess + alcohol + good conversation = patrician lifestyle
>>9356076It doesn't though. They already tried early intervention with chess, it didn't increase IQ.
>>9355345Definitely. I assume there to be multiple papers on said benefits. In my own experience (I like playing chess with different people) it gives you this strategic edge over others. Planning things like revenge, exposures cheating requires insight into every move a 'player' can make. That, in its essence, is also required in order to be considered a good chess player.
>>9355556yeah japanese chess is way better than chess oh wait
>>9356703It even influences speech. Personally I now carefully choose what to say and think over everything much more often, as to not give the opposing 'player' a opportunity to hurt me. You could call that experience but it doesn't feel like it to me.
How do we save math education?
>>9354885What the fuck does algebra models have to do with trig? I refuse to believe you didn't have problems were you need to identify triangles in some configuration.
>>9343642This would literally advance humanity millennia. Only in dreams, anons.
>>9343635Get rid of the excuses.No, don't sit there and stress out overthinking teaching and learning methods. You need to force a basic level of discipline and focus before the rest is even worth thinking about.No more grade inflation. Not even if other departments whine because Calc 2 is taking out too many of "their" students.No more passing people who don't know the material.No more giving leeway or even special attention to the "disadvantaged" and/or "minorities".If that isn't going to happen, then time spent stressing over the details of how math is taught is wasted.
Kill all chadsChads stop making babiesMath scores instantly improveAlso kill stupid faggots who can't do 6th grade math
Maybe like a primer to calculus in grade 9 as a prereq to show people why they are learning seemingly pointless shit.I dropped out of highschool in grade 10 never even learning algebra 1 and I recieved a bs in mech eng in my 20's. While I'm definitely an exception I don't believe that the issue is people are stupid or that intermediate math is an IQ filter. I feel like only an autist who's still bitter about his highschool experience could possibly think this. I don't believe there's anything conceptually challenging about algebra, trig, or calculus to someone within a deviation of normal intelligence.It took me sitting around wondering about material stresses and how to optimize design as an uneducated 21 year old to realize I need math and physics and why having intuitive knowledge of algebra was imperative for both.A lot of this is the parents job, but majority of parents are uneducated. They don't know the math or the point of the math. School system needs to level with kids instead of just going through the motions. They need to explain the purpose of these seemingly pointless algebra puzzle games. Because most kids don't have parents that give a fuck.. There's no reward for what they see as pointless busy work. A students are A students because of the parental or peer reward, they arent necessarily intelligent.There's a lot of other innate issues with standardized learning, but I think the above is a simple and quick way to motivate students that are bored which is probably the biggest issue outside of our culture of ignorance.
Is he the greatest authority on the subject of biology, /sci/?
No, he had a pseud understanding of biology.
>>9356680You have any molecular genetic proof to back that claim up, brainlet?
>>9356677Another YouTube faggot thread, seriously? Stop, please.
Who is he?
>>9356697The greatest genius of the 21st century.
I'd like to make a nice reaction with no material. I mean I have no material that is typical of a chemistry lab. So I'm wondering (I know nothing about chemistry): are there simple reactions you can make with poor tools and elements that you can buy everywhere? I am always fashinated by chemistry reactions but I've never could to start to try someone
OP I'm a chemistry grad studen (organic materials). You can ask me any questions you have and I'll answer if I can. I'll monitor this thread periodically for the next while.A pretty easy and fun one is to dissolve Copper (II) Sulfate, CuSO4, (can get from root killer) in water to make a beautiful deep blue colour that is an iconic copper (II) colour. Then add a piece of Zinc metal. You can get these pretty easy from C type batteries (it's the casing)You will see the solution almost instantly start to go clear with a dark brown powder forming and falling to the bottom as the zinc disappears. Its basically turning the copper ions in solution into normal copper powder, while dissolving the zinc.
>>9355985I’m currently getting my Chem degree and I can vouch for this, this was one of the first labs I ever did it was pretty cool at the timeThis was actually the last one I did in a series of 6 reactions to see if we could retrieve as much copper as we used in in the first reaction. The first one involved pure copper metal and mixing it with nitric acidThe reaction went this way:Cu+4HNO3->Cu(NO3)2+2H2O+2NO2Copper metal dissolved in the acid and produces water, a salt called copper nitrate which is dissolved in the water and gives it a blue color, and releases nitrogen dioxide, a kind of orange colored gas. It’s pretty neat.
>>9355985Different poster here, curious what your opinion is on something I wrote the other day, would a reaction like this work? Ni+2HCl->H2+NiCl2
>>9354211Ah yes, the classic "surprise thermite" trick. Great for birthday parties.
>>9356054Not the same guy but it won't work very well with HCl because of passivation. You'd need high concentrated HNO3 to get NIckel in solution.
Does anyone else on /sci/ work with Magnetic Resonance Imaging?
>>9356346i actually do, as a research assistant for a lab focussing on the investigation of MRI as a biomarker for musculoskeletal diseases, what you wanna know bruv
Can we have textbook thread? So, what are the best textbooks for brainlets willing to learn? My propositions: Linear Algebra - Linear Algebra Done RightCalculus 1 - Calculus - Early transcendentalsElectronics - Art of Electronics

>>9354648The alternative approach makes it questionable as a first choice of linear algebra text from what I can tell. Personally I'm going to start on hoffman and kunze soon. Imo if you're coming from a pure math angle (like I imagine you would be, if you were going to read axler), then you may as well go for hoffman and kunze for the more traditional approach, while still being rigorous and abstract.
>>9354629>not functionsAre you retarded, mate?Any operator can be seen as function:+: R2 -> R(x,y) --> z = x+y* : R2 -> R(x,y) --> z = x*y- : R2 -> R(x,y) --> z = x-y/ : R2 -> R(x,y) --> z = x/y

want to start a band one day but learning guitar, drums and vocals at 18, realistically speaking, is it too late?

I'm taking my GED tests(Mathematical Reasoning & Science) in February. Are there any ways I can adequately prepare or study for these tests, alone/at-home? I'd rather start from the basics of science and math but are there any programs that are specifically designed to teach education basics for GED students?
>>9356498khan academy
>>9356634This. Khan Academy is the best for high school math. You can start your way from kindergarten math if you need to
>The fact that so many textbooks still name π as "the greatest or most significant or most influential" geometric constant ever only tells you how far geometry still is from becoming a serious science. Physicists have long recognized that the greatest physical constants of all times are G and c, who were not the most famous or highly-regarded or best-known of their times, let alone of all times. Complex analysts rank the highly controversial imaginary unit over real numbers who were highly popular in proofs around Europe. Geometers are still blinded by commercial success. π was written about more than anything else (not true, by the way), therefore it must have been the greatest. Physicists grow up reading a lot of kinematic equations of the past, complex analysts grow up reading a lot of complex proofs of the past. Geometers are often totally ignorant of the geometry of the past, they barely know the best proofs. No wonder they will think that π did anything worthy of being saved.
>>9356552>τd^2/8Good job retard.
>>9355715>and then calculate the radius of the circle from the area>and then calculate the radius>the radius
>>9356644>τd^2/8HAHAHAHAHAHAHAHAHAHAHAHAHA
>>9355873>The area of a circle is certainly more brief, and therefore more witty, if you write it as [math]\pi r^2[/math] as opposed to [math]\frac{\tau}{2} r^2[/math].Since you insist on defining the circle constant from diameter rather than radius, you should do the same with area:[math]A = \frac{\pi d^2}{4}[/math]What a steaming pile of shit.

Where are transfinite numbers located on the number line?
https://en.wikipedia.org/wiki/Long_line_(topology)
>>9356438The "real" component is on the number line at what ever it's value is. "4" means "4"The "imaginary" component isn't on the number-line. We usually visualize a "number plane" with a 2nd axis at right-angles to the number line. "7i" is 7 units distant from the number line. So (4,7) is 4 steps to the "right" of (0,0) and 7 steps "up".
>>9356476>Proof of consistency for Peano arithmeticliterally Gödel's incompleteness theorems
>>9356001dey exist in platonc space :)
>>9356244You have infinite real line, and behind it, after it "ends" there's another line for transfinite line, such that every element on that line is greater than anything on real line
What is better, free groups or symmetric groups? Every group is a free group mod some relations between elements, but also every group is a subgroup of some symmetric group, so which property is better?
>>9356610How is it stronger?
>>9356610But since symmetric groups are also a free groups mod representations then the first statement gives us the latter, right? And it's better since it's more general>>9356566>graph theoryCS monkey go away
>>9356615It's just rarer in general. It says you have a functor !: Set -> Grp such that any object is a subobject of some X!. Indeed G <= U(G)! - I don't feel like checking but this should be natural in some sense. Basically any algebraic category will have free objects but there aren't a lot of others where the above is true (maybe lattices/semilattices/partial orders?).
>>9356619>But since symmetric groups are also a free groups mod representations then the first statement gives us the latter, right?No. Then it would be stronger, not weaker.
>>9356627Actually it's also true for graphs - just take the complete graph (with loops if that's allowed).

The only reason anybody goes to university for an undergraduate degree is the artificial value it has. The internet and free market have completely rendered university obsolete as an educational tool, so when will it finally fucking die already?
>>9351275>It's another early December on /sci/All you had to do was fucking study
>>9356178kek, so true. Always fun to see all those whiny freshmen after finals week.
>>9351829"the real world"Why do you glorify being chained to menial work? The point of university is to be better. The point of tech is to be better. Praise yourself for your tribal being-a-real-man mentality, but the point of civilization is to insulate people from nature and free them for higher pursuits... like relaxing at university doing research instead of hunting and foraging.
You're all wrong. University is not worth the price tag outside of Europe, university is not for everyone, a degree is not a guarantee for a job, most degrees are useless, and given that degrees are quality controlled and education is delivered by authorities on a given subject, the internet can never replace them.
>>9351275you go to college to make friends and fuck girls, it's a breeding ground.
Just curious, why do people on 4chan Shit on biology majors so much? I've never really seen that before. Not trying to b8 or piss people off, I genuinely want to know.
>>9354321We have biophysics you know
I always like the Gaia hypothesis, even if I don't believe it.
Good luck trying to understand a living organism using pure maths or physics. Even chemistry falls short when it comes to emergent properties.
Looking at doing a double major in bio with one being ecology, i got multiple options for doing a second but haven't given a lot of thought about what I want to do aside from doing field work/academia. My options are eco+evolution, eco+microbiology/immunology or eco+geology. I don't know what to pick in regards to future outlook of jobs, I feel that evolution is more memey and doesn't have any use outside of academia.
