Something went wrong with the way math is taught at school. We teach math as a tool and not as something that can be appreciated and enjoyed the way we appreciate and enjoy art. Some math theorems and their proofs are a thing of beauty. Often one doesn't even have to understand all the nitty-gritty details to see that beauty. Some basic understanding of fundamental principals often suffices.

Konohamaru 6y ago
You cannot teach people--even people at a young age--to enjoy mathematics because mathematics is based on logic and almost everyone except for a few weirdos hates logic. Mr. Spock was designed to point out how unusual people who like logic are, but as a character from a minstrel show, not as a role model....

  Joan Pearce and Peter Sloman of De Forest Research, Inc. were probably unusual people who like logic, having provided the science feedback for TOS. Some other people certainly found Spock to be a role model in 1968: https://ca-times.brightspotcdn.com/dims4/default/6870952/2147483647/strip/true/crop/2048x1152+0+0/resize/1486x836!/quality/90/?url=https%3A%2F%2Fcalifornia-times-brightspot.s3.amazonaws.com%2Fe8%2F48%2Fa53c9754a0696b5e07fc282af2af%2Fla-1495640638-sp1m7wejsr-snap-image https://ca-times.brightspotcdn.com/dims4/default/6870952/214...

  These design requirements in regards to Spock that you remark on - I can't really find them here https://en.wikipedia.org/wiki/Development_of_Spock https://en.wikipedia.org/wiki/Development_of_Spock and though never a Trekkie I don't think this sounds like something Roddenberry would have considered.
  - Konohamaru 6y ago
    Did Gene Roddenberry research biographies of logical people such as physicists, number theorists, and other "heavy researchers" (for a lack of a better word) before he wrote or specified the character? If not, then he was very ignorant of the personality type of heavy researchers. It seems that Spock and Surak were meant to be parodies of stoic philosophers such as Marcus Aurelius. The fact that Surak is listed as a "great mind" alongside Newton and Einstein in the series reflects Roddenberry's high view of stoicism, so perhaps I was too extreme in the judgment of "minstrel character," seeing that he, Surak, and T'Pau were meant to reflect his favorable judgments of Stoicism, but it is still ignorant because 1. Nobody considers the stoics to be legendary thinkers in the real world. Nobody says "Aurelius, Einstein, and Newton." 2. Heavy researchers aren't at all like Spock but he does have a resemblance to people with Aspergers 3. How heavy researchers feel emotions is not at all like stoics. Strongly externally-oriented thinkers feel emotions and see emotional events in a specific way and "like Aurellius" isn't it.

  I disagree. Mathematics is a tool to practice our hobbies .. see Feynman‘s biography. Rot mathematics is where it goes wrong. Meta mathematics, abstract, detached from real life, as alot of the academy with its publish pr perish thinking ... that produces pain. Existential voids filled with an exercise that does not help many to move forward optimally. saying weirdos hate logic is extremely dismissive to a lot of what I would call the human experience. The same stuff can be taught with soul and purpose If we actually show children how they can apply mathematics to improve and enhance what they’re actually doing whether it is building castles in Lego, Or designing faster toy car, A better school project volcano, etc

  Mathematics is as much logic as poetry is grammar. Sadly most people don't know that because they never get exposed to the creative/discovery side of math. Logic is just a tool to check correctness and enable communication.

    Logic goes beyond truth tables: it's about being able to see the simplicity and symmetry in objects. That's why it comes from the word /logos/ which means "prevening order" (see Gospel of John).

(Here I am focusing on math outside of the math taught in pure mathematics programs.) If anything the focus on math being a tool should be even bigger than it is today if you ask me. Most if not all of the math you get taught in school is math that was invented to solve a problem, it was not created as art. Introducing this historical context would probably help students in understanding why learning math is useful instead of just teaching math without this context as is usually done today. The beauty, in theorems and their proofs, comes in my opinion from understanding the nitty-gritty details. Without understanding the logical steps it's hard, at least for me, to understand where the beauty lies. I cannot appreciate mathematical ingenuity without understanding it. This is a bit of an abstract question, but perhaps you could elaborate on how you see this beauty without understanding?
- curiousllama 6y ago
  Not OP, but I agree with OP, assuming by "people" they mean "people already inclined towards math." Self-evidently, IMO, most students need numeracy much more than they need pure math. In school, I struggled with memorization & attention to detail. For the life of me, I couldn't quite finish an algebra-heavy problem without writing 3*4=15 or outright skipping a step in a conic rotation or whatever. I'd get dinged every... single... time, and got relatively bad grades. Shortly later, when I arrived back at higher level math through cs & stats, I could ruin the curve in my applied classes. I'd relied so much on mathematical intuition early on to compensate for a lack of memorization ("what are the steps again? Whatever - I'll just think it through now") that I was quite good at putting pieces together in odd ways to solve data science problems. Not to mention - with proper context, as you say, all that linear algebra that so annoyed me all the sudden seemed intuitive. "OHHHH so THAT'S why this exists" I was first driven out of math by a relentless focus on math-as-a-tool, and was able to return at a level where it became more about creating new logic. I'm convinced that I would have thrived in an earlier class that focused on elegance & logic - what makes a good proof? - and I'd have stuck with it.
  - cinntaile 6y ago
    While I can relate to your complaint that some steps were a bit too simple to include... The point of all those steps was precisely to show that you hadn't memorized the results. At the risk of overly simplifying high school maths (it's hard if it's new) I would say that in high school the math is quite basic. You could pretty much remember the first step, not get most of it in between, and still produce the right answer because you remember the answer format. It's just not feasible to have a individual discussion with every student to see if they really understood the material. Requiring students to include the steps in between is a way to prevent memorization, although maybe not the best way for each student. It's good that the same thinking served you well later on though!

  That's a fine book. But to answer that question surely calls for emperical data?

      This was downvoted, but I think it's an interesting argument, in this context and in general. Should we be rooting for things that make supply of labor in our field more plentiful? Wouldn't it be in our self-interest to prevent as many people as possible from learning math and computer science? One could argue it wouldn't be in the interest of humans as a species, but I'm skeptical that the marginal loss to each of us is greater than the gain.
GaussBonnet 6y ago
The problem isn't that grade school teachers are sitting on a secret stash of cool theorems, and instead diabolically choose to have students solve quadratic equations year after year. It's that no one in the grade school pipeline has any experience with actual, modern, proof based mathematics. They've never even heard of analysis or group theory. Their knowledge does not extend beyond the latest meme textbook with MULTICOLORED (whoa!) text. There is no communication between modern mathematicians and grade school teachers in America; they may as well live on separate planets. Math classes in American grade school are little more than busy work meant to weed out people who hate busy work. Infer from that what you will.
- dorchadas 6y ago
  Yes, yes, and absolutely yes! I'm a high school math and physics teacher (who majored in physics, not education, and is now doing self-study in more proof-based mathematics), and so much the issue is in grade school, in my opinion. The teachers there don't appreciate math. And, more than that, they don't understand math. Lots of them don't have a good well-developed number sense, so it's no wonder our kids don't either! Then the problems compound when they just give kids calculators without the kids understanding why the calculator works, and by the time they get to high school hope is lost because they have no number sense and we're trying to explain variables and such...often divorced from real life. I've found my kids get a much more intuitive sense of slope when I explain it as the rate of change rather than "rise over run" that they're so often taught in middle school. Give them examples, like amusement park tickets (it cost $50 to get there, then $70 per person) and have them incorporate that into a slope-intercept form. It just makes things so much clearer that they often don't get because they don't have the number sense and because many teachers don't understand/appreciate math.

  So the way to get kids to like Math is by forcing them to learn... proofs? Not learning how it applies to the world and solves problems, but how it can be used to impress professors who care about rigor/pedantics? Math is dirty. Math was created by businessmen who wanted to be monopolists. By gamblers who wanted to win, or at least to postpone the day when they would go broke. By scammers, and those who wanted defense against scammers. By people who wanted to blow up their enemies in war and who were moved by hatred and revenge. A recent mathematical construct born out of academia wants to destroy the US dollar and turn the world economy upside down. There are people trying to take over another planet with Mathematics. Others are trying to achieve geopolitical supremacy building artificial intelligence and robots armies. Mathematics is blood. Mathematics is power. There's a disconnect between academics and how real humans think if the modern solution to Math education is proofs.
pastrami_panda 6y ago
I can't agree more. Speaking as someone who never enjoyed math at school, but now have an avid interest in it - the thing that converted me was building stuff with math. Much like you talk about. When we learn woodworking we learn some basic tools and how they work, and then we build stuff. In my experience we don't typically get to build stuff with math. At least not the type of stuff that most people find remotely interesting. I'm now building stuff with math all the time and enjoy it alot. The set of projects to choose from must be diverse though, some math isn't for everyone, just like not all kids will find working on building a baseball bat rewarding.

Floating points are absurd. It helps the scientific community and slows us down to solve interesting frictionless problems. Floating points take too much computation power. The amount of power we spend for floating point math and return on knowledge gained doesn't make sense. A: Hey, but floating points are main thing in scientific problems. Me: Ignore scientific problems, it doesn't amount to nothing and scientific problems doesn't bring a smile on face. By the time we solve, we would have lost our sense of self. And that's why it is meaningless. A: What do you propose? Me: Not proposing anything. Just putting my thoughts out. Chase only whole numbers. Even try to cut out division. It is the root cause of all the problems. Me: Addition makes sense, Multiplication makes sense. Subtraction doesn't make sense. It is used to check the correctness not for real math. You may call, just like multiplication is repeated addition, division is repeated subtraction. I'll stop right there. Division gives two answers - reminder and a quotient. Both are useless. IF YOU HAD FUN, I'm glad.

agumonkey 6y ago
I'd say wrong and wrong :) respectfully of course. School removes the pragmatic nature of math thus cannot even teach it as a tool because there's no concrete goal (worded problemes are not in situ enough). The beauty may evade some souls, they're just not in tune with the subject at that time.
mechaniker 6y ago
I'm not even convinced that schools teach math as a tool. Too few students are aware of the raw power that learning how to think mathematically and use mathematical knowledge as a problem-solving tool gives them. It provides new insight into fields as diverse as visual art and as applicable as physics. The latter of which only became the potent subject it is today after being mathematized. Forget about about students, there are career programmers out there who only began their careers after a google search on whether they needed math to be a good programmer assured them otherwise. It's so ridiculous to me that I can't help but feel that some shadowy worldwide illuminati-esque force is intentionally sabotaging mathematical education to keep the populace unaware of how much more capable they could be when fully trained in mathematics. (Why would they do this? I don't know, but I think it has something to do with the pyramids.) Jokes aside, I do wonder what the flaws in the mathematical education system are. Anecdotally, I've found that the truly skilled mathematics students rarely go into teaching careers, which is understandable. One of my favorite mathematics books, How to Solve It by George Polya, outlines a style of teaching that requires the teacher to be as much a confident performer as well as a skilled mathematician. It's worth saying that Polya was Hungarian, growing up at a time that mathematics teachers were expected to have serious postgraduate qualifications. Whilst it would be nice to go back to such rigorous standards, I can't imagine the resulting lack in qualified teachers such a policy would produce...

Very, very strongly disagree with you. First, some of the most beautiful math stemmed from an attempt at solving an actual, practical problem, and the path the "discoverers" of such math followed to get there is often profoundly different from the way it's taught. Your view, which I've been subjected to by most of my math teachers my entire curriculum is the exact reason why most people hate maths because it feels like a bunch of very complicated and hard to learn stuff that seems to serve no purpose whatsoever. When you've been learning a bunch of very theoretical stuff for decades and finally find an actual application / use for it, my experience is that: - you do *then* see the beauty of it - you curse your math teachers and their ancestors to the seventh generation for not having shown you the practical application of the (typically over-generalized) theory he/she was force-feeding you back then.

Give them examples, like amusement park tickets (it cost $50 to get there, then $70 per person) and have them incorporate that into a slope-intercept form. It just makes things so much clearer that they often don't get because they don't have the number sense and because many teachers don't understand/appreciate math.

So the way to get kids to like Math is by forcing them to learn... proofs? Not learning how it applies to the world and solves problems, but how it can be used to impress professors who care about rigor/pedantics? Math is dirty. Math was created by businessmen who wanted to be monopolists. By gamblers who wanted to win, or at least to postpone the day when they would go broke. By scammers, and those who wanted defense against scammers. By people who wanted to blow up their enemies in war and who were moved by hatred and revenge. A recent mathematical construct born out of academia wants to destroy the US dollar and turn the world economy upside down. There are people trying to take over another planet with Mathematics. Others are trying to achieve geopolitical supremacy building artificial intelligence and robots armies. Mathematics is blood. Mathematics is power. There's a disconnect between academics and how real humans think if the modern solution to Math education is proofs.

I can't agree more. Speaking as someone who never enjoyed math at school, but now have an avid interest in it - the thing that converted me was building stuff with math. Much like you talk about. When we learn woodworking we learn some basic tools and how they work, and then we build stuff. In my experience we don't typically get to build stuff with math. At least not the type of stuff that most people find remotely interesting. I'm now building stuff with math all the time and enjoy it alot. The set of projects to choose from must be diverse though, some math isn't for everyone, just like not all kids will find working on building a baseball bat rewarding.

Floating points are absurd. It helps the scientific community and slows us down to solve interesting frictionless problems. Floating points take too much computation power. The amount of power we spend for floating point math and return on knowledge gained doesn't make sense. A: Hey, but floating points are main thing in scientific problems. Me: Ignore scientific problems, it doesn't amount to nothing and scientific problems doesn't bring a smile on face. By the time we solve, we would have lost our sense of self. And that's why it is meaningless. A: What do you propose? Me: Not proposing anything. Just putting my thoughts out. Chase only whole numbers. Even try to cut out division. It is the root cause of all the problems. Me: Addition makes sense, Multiplication makes sense. Subtraction doesn't make sense. It is used to check the correctness not for real math. You may call, just like multiplication is repeated addition, division is repeated subtraction. I'll stop right there. Division gives two answers - reminder and a quotient. Both are useless. IF YOU HAD FUN, I'm glad.

We make circular cpus and do everything in base pi! Yes!

I'd say wrong and wrong :) respectfully of course. School removes the pragmatic nature of math thus cannot even teach it as a tool because there's no concrete goal (worded problemes are not in situ enough). The beauty may evade some souls, they're just not in tune with the subject at that time.

I'm not even convinced that schools teach math as a tool. Too few students are aware of the raw power that learning how to think mathematically and use mathematical knowledge as a problem-solving tool gives them. It provides new insight into fields as diverse as visual art and as applicable as physics. The latter of which only became the potent subject it is today after being mathematized. Forget about about students, there are career programmers out there who only began their careers after a google search on whether they needed math to be a good programmer assured them otherwise. It's so ridiculous to me that I can't help but feel that some shadowy worldwide illuminati-esque force is intentionally sabotaging mathematical education to keep the populace unaware of how much more capable they could be when fully trained in mathematics. (Why would they do this? I don't know, but I think it has something to do with the pyramids.) Jokes aside, I do wonder what the flaws in the mathematical education system are. Anecdotally, I've found that the truly skilled mathematics students rarely go into teaching careers, which is understandable. One of my favorite mathematics books, How to Solve It by George Polya, outlines a style of teaching that requires the teacher to be as much a confident performer as well as a skilled mathematician. It's worth saying that Polya was Hungarian, growing up at a time that mathematics teachers were expected to have serious postgraduate qualifications. Whilst it would be nice to go back to such rigorous standards, I can't imagine the resulting lack in qualified teachers such a policy would produce...

Very, very strongly disagree with you. First, some of the most beautiful math stemmed from an attempt at solving an actual, practical problem, and the path the "discoverers" of such math followed to get there is often profoundly different from the way it's taught. Your view, which I've been subjected to by most of my math teachers my entire curriculum is the exact reason why most people hate maths because it feels like a bunch of very complicated and hard to learn stuff that seems to serve no purpose whatsoever. When you've been learning a bunch of very theoretical stuff for decades and finally find an actual application / use for it, my experience is that: - you do *then* see the beauty of it - you curse your math teachers and their ancestors to the seventh generation for not having shown you the practical application of the (typically over-generalized) theory he/she was force-feeding you back then.
