I sometimes wonder if math fags aren't just making shit up to sound smarter to non math fags
>>281902546Maybe on an individual level of more egocentric people, but on the whole, no.The whole point of mathematical proofs is to do the exacty oppposite: to show deductively why the result you got is irrefutably true. THe idea is that you can write it down in a textbook and go through the steps yourself and come to the same conclusion, so you can't be making it up but you are discovering why sometyhing is true.
>>281898813i got that as well.
>>281898216I knew you only have to check numbers up to root(1024) but I forgot why. My answer was 5 when it was supposed to be 5 pairs. Partial credit?
>>281902546It's the jargon. High level anything that requires mathematics will sound like gibberish to anyone who doesn't speak the language. Works great for communication between people who already know what they're doing, not so great when it comes to teaching kids or trying to communicate ideas to the non-specialized. I'm convinced the reason a lot of math and science educators are shit is that they just never took the time to learn what the stuff they learned is actually saying. Only good math teacher I ever had was my high school calculus teacher, that guy took most of us from not having a clue to understanding exactly what basic calculus was doing in like two sessions. Teachers like that are a godsend and a rarity.
>>281905774Good post.>I'm convinced the reason a lot of math and science educators are shit is that they just never took the time to learn what the stuff they learned is actually saying.They do but as someone in a STEM field, most education nowadays is focused on immediate application rather than understanding what is being said and applying it. That's why most math and science professors/teachers don't really communicate what they are trying to say in laymen's terms and just go form equation to equation: the idea is that you will use these equations in your future career and essentially plug and chug your way through to a solution. That takes away time that could be used to actually implement something that uses these principles.It's ultimately a result of the space race and how we won it be focusing mostly on quick calculations compared to deeply thought out reasons as to why these results were true. That and the various new schemes of teaching math that really didn't address this problem.
>>281903718You saw it as "x is equal to double the previous number in the sequence plus n where n = 1 + 2(the position of this number in the sequence)", correct?I assume you get 143 by multiplying primes, I wonder how closely you can approximate that sequence something like our answer. Not enough to figure it out, but I wonder.
>>281899075there is one good one about an older mathematician whose lost his passion regaining it by teaching a budding prodigy. Forgot its name though.
>>281898216suugaku girl? On /a/ in current year?
>>281902641See that's all well and good but I just have trouble seeing the physicality and practicality of more advanced stuff. >>281905774I've never had a good math teacher. They always seemed to just assume we were all starting on the same level. He was also not a patient man and I was a smart ass.
Sometimes I thought I'd like to learn math better but I wouldn't know where to fucking start. I opened up a calculus book once and it was like busting open fucking Gilgamesh in the original Sumerian. I asked one of my friends once and he tried to explain it and I tell him to stop speaking goddamn Klingon. I do not know where they want me to be at. You know where my retarded ass is? 2+2. Long division still gives me a migraine. I don't even want to look at the retarded shit they got my nephew doing these days. math blows.
>>281908340Imaginary numbers were written off as a meaningless curiosity until they started solving important problems. Electrical engineers use them regularly to calculate resistance. Hamming codes were useless until the voyager probes needed powerful error correction to fight interference from solar wind. Analytical continuation is so far out there you'd think it couldn't possibly relate to reality but it's being tentatively used to renormalize parts of quantum mechanics. The greeks never discovered negative numbers because they have no use in the geometry they were doing. Their first practical use? Tracking debt.All this to say, math is always impractical until it isn't. I didn't mean this post to be accusatory. I just love math.
>>281908340A lot of that advanced stuff is used in tecvhnology you use everyday, from cryptography systems using number theory, computer graphics using geometry, control systems using analysis and prety much everything using analysis and linear algebra to model changes in state. You're thinking too locally frankly. If electrical engineers have to do proofs to make sure the systems they build (whether they be power systems, communication devices, robotic systems, etc.) are essentially comfirmed to work under 99.9999% of non-extreme usecases and physics engines in video games and in scientific simulations have to be designed to use certain types of integration schemes in order to make sure the physics of the system are stable, then it's not really the problem of the math being useless so much as you not really knowing how or why you would want to use it.>>281908434Math doesn't suck so much as most people don't really need it and honestly they shouldn't bother with it if they don't need it. Until you get to the realm of mathematical foundations or more abstract types of algebra/geometry/topology that have pathological behaviors you really can't explain in natural language well, most of math is very managable if you reference the definitions, try to study examples and related proofs to the concepts and do problem sets that build upon this knowledge It's for a specialized group of people that either are interested in the application of mathematical tools in the realm of engineering and the natral sciences or advancing our knowledge of mathematical tools in the realm of pure math.
>>281902546if you can't maths you ain't human
>>281908645>Their first practical use? Tracking debt.That comes as no surprise. >>281908651Well that's sort of the problem, I think. We're not really told what to think. It's the whole "I don't know what I don't know" kind of thing. >Math doesn't suck so much as most people don't really need it and honestly they shouldn't bother with it if they don't need it.This is kind of the ironic part of it all. I've always been more a history, literature nerd and one of the big issues I get there from other people is why do we have to study history, why should I read this book? And I don't like it being treated dismissively just because it doesn't immediately apply to them so I don't like saying that about math even if I can't understand it with a gun to my head. Even if it's outside my wheelhouse I think there's value in knowledge even if it's for knowledge's sake.
>>281908434Your roadmap is basically the same as in your formal schooling. Read an algebra textbook and a geometry textbook (check /sci/ or whatever bro idk I learned this shit for compsci) because algebra is basically the fundamentals of mathematical operations and geometry is baby's intro to proofs and related crap (if you really understand both of these concepts you will be better than most graduating highschoolers in the US).Calculus is basically learning another pair of operations that build on top of the knowledge you gained in algebra and have a lot of implications and edge cases you need to memorize. I actually recommend that you supplement your learning with youtube videos for visualization. Once you've understood most of this, the rest of the field starts to really open up.Also at some point you will have to grapple with the idea of coordinate systems unlike the one you play battleship with and they are sadly occasional useful.Arithmetic is (unironically) a muscle, brother. If you challenge your cognition I do not doubt you will find things come to you more easily, but the challenging yourself part is tough (for everyone). I don't know if this is good or bad advice, but try to break calculations into convenient chunks when doing mental math (I.e, instead of calculating 40% of X, think of it as one tenth of x times 4, or 8% as one tenth of one tenth and doubled three times). And lose your fear of decimals/fractions/percentages (these all express the same thing and I remember hearing a lot of people had trouble with that) if you have one.
>>281905774As someone who has actually had to do some education in a hands-on subject, the most valuable lesson that I learned early on is that you absolutely can not take your own knowledge for granted.You have no idea whether your students know something already until they show you that they know it. That includes terms and basic concepts that you are already used to thinking in, especially when talking to your own peers. And in order to teach them effectively, you need to learn how to take your own internalized knowledge and be able to break it down to its barest essentials. Not only is that necessary for imparting that knowledge, it's also a good test for yourself to ensure whether you truly grasp a concept that you think you know.
>>281898216did the Galois Theory volume ever get translated?
>>281908724>And I don't like it being treated dismissively just because it doesn't immediately apply to them so I don't like saying that about math even if I can't understand it with a gun to my head. Even if it's outside my wheelhouse I think there's value in knowledge even if it's for knowledge's sake.I actually agree with you. Studying some field for it's own sake is a good thing and frankly most mathematical discoveries were and still are being done for the sake of just knowing more about mathematics. I just realize most people don't really like being educated in general. They learn things so that they can make more money, get friends/women, get socia status etc. The type of person that likes education for the sake of itself (or for a seconday goal like a mechanical engineer learning physics so that he can build mechanisms, which is his true passion) isn't going to relate well to the average person when it comes to these things.(cont.)
>>281898216>1024>1 1024>2 512>4 256>8 128>16 64>32 3211 factors. That took a little while to figure out mentally. Probably should have just used a calculator. It was pretty easy to figure out factors up to 16 but then doing the mental math to see if 17 through 31 multiplied in was a pain. There's probably some math trick or algorithm that would make figuring it out way easier then just mentally going up in multiples of 21 until you realize it wont go in evenly.
>>281908883>Well that's sort of the problem, I think. We're not really told what to think. It's the whole "I don't know what I don't know" kind of thing.That's the thing about math: you're not supposed to 100% rely on someone else's work or thought process becasue you might not understand it or it may just be wrong. I'm not saying it's not a good starting point, but always be wary of other people's thought processes, since they can arrive at a right answer from wrong premises or just forget integral points and come to the wrong conclusion. Think if it like a being detective in a murder case. The person telling you some piece of information mught be bullshitting you, trying to cover their tracks or just forget key points. You have to get to the source and get all the clues to arrive at the right suspect.The best thing to do, from what I've seen, is go to a Wikipedia article on some math subject and read it so that it becomes clearer becasue their write up on math,the harder sciences and engineering are top notch actually. If that still brings up questions, I'd list them out first on a piece of paper and just try and do a combination of googling the answers of said questions and looking in textbooks (via any other book pirating site since they can get expensive) to see if they address that point. If and when they do, just note it down on that piece of paper and keep on reading until you think you have a hang of it. After that point, look in the textbook to do some problems to see how well your understanding of the concept is. If you do well, move on to the next topic. If not, go over it and see what you did wrong and then retry that section with different problems until you get the concept in your head well enough.>>281908781>if you really understand both of these concepts you will be better than most graduating highschoolers in the USChrist that's grim.
>>281908944NTA, but as someone who graduated high school in the US taking honors math classes, I remember almost nothing from the levels of material beyond the first year of algebra, just because I don't use it. I know people who graduated from the same school who can't do any math with variables beyond the most obvious stuff.
>>281909010I can understand that. I don't remember any of the English literature shit I had to cruch for my AP Lit exam. No need to hold onto useless knowledge. I'm just surprised that graduating seniors (from what I gathered from what he other anon said) don't even have that knowledge base of algebra anf geometry when they graduate. That's actually concerning. What are they doing and how do they expect to go anywhere if they don't even know that getting out of high school and going into college? That shit is fundamental and even if you don't use it, you'll still need to have a basis in it to function as an adult.
