# learning math in your 30s

Anticipate questions taking you six hours to solve, leaving your table and floor strewn with the history of your consciousness. Sometimes, I need some of the groundwork to be laid down for me - at least, when it comes to things like maths and scientific ideas. I picked up various books and different learning strategies along the years but couldn't move forward cause I could not see any practical use for what I was trying to learn. https://ocw.mit.edu/courses/mathematics/18-06-linear-algebra... Optimization course & book link (Stanford) https://web.stanford.edu/~boyd/cvxbook/, Statistics: http://greenteapress.com/wp/think-stats-2e/. But at thirty, you have the luxury of not worry about midterms and finals and you probably can afford multiple books. The second pass is a semester of classical mechanics covering Lagrangian and Hamiltonian mechanics, a semester of statistical mechanics and thermodynamics, a year of electromagnetism, and a year of quantum mechanics, paired with a year of mathematical methods (linear algebra, special functions, curvilinear coordinates, a little tensor calculus, some linear partial differential equations, and a lot of Fourier analysis) and a year of more advanced laboratories. Deep diving into math and physics just for the sake of learning etc seems to be cargo-culting. As a teenager, having a ton of friends was important to you, regardless of the value they added to your â¦ When it comes to friends, it really is about quality over quantity. Taste, you say? I realize I didn't have the need for it and didn't have the right exposure (environment/friends) that would have inculcated in me these things. Read it for intuition, motivation, the story of Mr. Bader, and entertainment. .... read this inspirational article! The Feynman Lectures on Physics. Take refresher classes at community college. Spend time on math websites (like this one! Honorable mentions: 3Blue1Brown[11], Numberphile[12], Veritasium[13], StandUpMaths[14], SmarterEveryDay[15]. ", That said, if I had it to do over again, for the money I spent, I wonder if hiring a graduate students/postdocs or even professors as tutors would have been better. We all know what this feels like - we've forgotten most of what we've learned in college that we don't use in our profession. It took about 3 years of exactly ops method. Get a piano, look up the basics of how to read music, find the keys on the piano, see my post on music theory and the Bach cello piece, get a recording of some relatively simple music you do like, get the sheet music, and note by note learn to play it. (You can get previous versions to save money. All the code is open, so you can learn from it. (Along with whomever you show it to -- I did a lot of college homework using LaTeX. Anticipate having to read three or four different treatments of the same thing in order to get a real understanding. But there it is again. I probably cannot work with formal physics or mathematics but I was able to learn a lot of the concepts behind the formulas and calculations and I believe that is much more important, at least, at first. Want it bad. Well, there are several different ways! Is it that the text you’re referring to? So it is good to re-read, go back and forth and play with the ideas. By now you will be seeing manifolds and fibre bundles. Best wishes to you. Standard analytic geometry and calculus of one variable. Regardless of whether you will actually put a maths degree to use on the job market—which no doubt you could, once you attain it—pursuing one can bring great rewards. Is it taught in the Coursera course you mentioned? My professor for dynamics and mechanics of materials required homework to include diagrams of the problem, neatly drawn, on unlined paper. > I can totally see that these are the folks who have high IQs and they can easily learn a new domain in a few months if they were put in one. 2. ), and join a forum (like the Math is Fun Forum). It is cheap and very didatic. Susskind's first book comes in here. Don't get stuck: Physics people commonly do math in really obscure ways; mostly they are thinking intuitively; generally you can just set aside after a first reading what they write, lean back, think a little about what they likely really do mean, derive a little, and THEN actually understand. As a sysadmin, I was always reading all sorts of subjects and pursuing different hobbies that further expanded my knowledge. Violin: Much the same except need more help at the start. IMO the best book you can drill questions from is Boas' Mathematical Methods in the Physical Sciences. Next up, differential geometry, tensors, and GR.... Google is your friend. Maybe you could find a buddy to work with, like people do with the gym or whatever to shame each other into staying on task. After 3-4 such pieces, get an hour of piano instruction and continue on. Look at images of violinists and see what rests they are using. You could go to the library and check out different math books! Before going to Khan Academy, I started reading a rigorous math textbook, but my motivation didn't last long. The difference for me is that I'm fairly certain that I'm one of the least accomplished people responding to your post. Your "users" inevitably catch a lot of them at "runtime". (5) Finding someone to talk to is really useful. > If you're working with graphical concepts, why not code them up, or use a drawing program (or hey, a graphing calculator) rather than pulling out a ruler and such (and maybe learning to draw at all if you don't know how)? Hint, Apply the FONC (first order necessary conditions for an extremum) to the functional (now the Action) in question. Participants in warm rooms performed significantly worse than those in cool rooms, failing to identify almost half of the spelling and grammatical errors (those in cool rooms, on the hand, only missed a quarter of the mistakes). Pen, graph paper, and maybe a calculator. Now here is a very, very, important point. You sit down in a warm or hot room, and solve them. I'd recommend the following "schedule" to absorb things into y memory permanently. Take him up on his offer. Griffiths! Supplement Susskind's second book with Griffiths intro QM book. No, writing a math textbook involves (perhaps) thousands of things that might be wrong, none of which will have any impact on one another. To apply to have him as your director of studies, fill out the form at the bottom of https://edeeu.education/alexander-coward. -- J.J. Sakurai, (Incidentally, I tried reading Sakurai's Modern Quantum Mechanics on my own once and was immediately curb stomped. For best results you need to make a nice LaTeX set up. Like other commenters I'll also repeat: Do problems, problems, problems. But it's desirable that students (or just people learning the same material, later) spend some of their undergraduate time learning new things, right? If you're doing it to learn, don't sweat about the prestige of the place. I have no idea why someone would have down-voted you - Spivak is brilliant. This will expose you to cutting edge research going on. Includes chapters on sets, graphs, calculus, linear algebra, and more! Certain modern enhancements are worth a qualified mention though. So don't think "I read 2 pages today", instead think "I understand graphs better now". What are you actually curious enough about to spend some time poking at? Good. You have to know if this is the case. I'm pleased if I can make it through a chapter at all on any time scale, and I think having low expectations is probably healthy. Hi, I calculated it basing it on the super-memo algorithm. The real difficult part is finding all the time it takes and also finding company that has similar interest and is willing to invest time seriously with you. If you're prepared for all that, and it's a price you're willing to pay, there is no reason to not simply start now. What you do need, however, is a perspective. I'm doing my OU Masters in Maths now, in my 40s. Not to mention the degree you are awarded if you succeed. Stuff like this will help you see where more advanced mathematics comes in. Currently a biggie is a lot in probability theory. I'm glad we have it. Essential Math 30S Geography 20F Rugby and Dragon Boat Contact Me Formula Booklet. But, if someone can continue to learn math their whole lives, it must not be impossible to start. Instead of ruing missed opportunities, I want to take it under my stride in my thirties to learn math/physics so as to become better at it. Decide if you want to learn physics or applied mathematics. Physics, in comparison, is relatively constrained. (4) You need guidance on what is important and what is not. Mostly you want linear algebra over just the real or complex numbers, but nearly all the subject can also be done over any algebraic field -- Nearing does this. I can recommend anything Jeremy does, sight unseen. One text (Wangsness E&M maybe) had a great student quote, roughly “I understand the principles but I can’t do the problems.”. One thing a friend of mine said, which I think has been very good advice, is to get several books on a single topic. Would you like to see a draft? Halliday & Resnick (or one of its later updates from Crane) is a better bet in this regard. Giancoli's book doesn't use calculus. ), and join a forum (like the Math is Fun Forum). I understand that starting to learn math is harder than continuing to learn math. I know I'm cut from a different piece of cloth as those people (and I don't mean that resentfully - I just want to be realistic about myself). It won’t be enjoyable but being examined on what you learn will provide focus. Differential equations, if you took physics that did not use them, can have a very similar problem, where you just grind through problems for a semester with no motivation.). I use the Skim PDF reader so that it autorefreshes on file save, and set up a Makefile and make it so the PDF is recompiled on every file save. If you are located in Los Angeles, I would recommend looking into the Michael Miller math class series taught thru UCLA extension. You might find my site interesting. It's okay but I have yet to derive more utility from it than from various field theory books. While I agree with you, and love aj7's post, I'm going to push back slightly on the pen and paper. Which WILL have, probably already does, an effect on your learning process). Others find it hard to learn because of bad habits and a poor foundation (their semantic tree wasn't that well built up in their youth). https://en.wikipedia.org/wiki/Mathematical_Methods_in_the_Ph... First of all - great idea! Start with a really easy book that starts with just Gauss elimination for systems of linear equations -- actually a huge fraction of the whole subject builds on just that, and that is close to dirt simple once you see it. Took me months to get though chapter 1 :D, but gave me through understanding of how to think about maths and how to prove stuff and that proof are the real fun of math. you will have to understand analysis. I also recently started watching some of Dr. Norman Wildberger's math lectures. 2199 cards and counting, Math is something that needs to be learned by rigorous practice. The applications range from physics to economics to machine learning and cryptography. It's not so much the provision of learning materials that I'm frustrated with but the process of testing and retaining what I learn. Incidentally this is a great way to learn about uses for Green's functions... And if you dive deep, your first look at singular integral equations in field theory. That algorithm is more sophisticated and geared towards cards / smaller pieces of knowledge; but I think it works equally well as "re-study" / "re-learn" reminders for larger chunks of material. Reading, Massachusetts, Get some good advice on how to hold the violin and the bow; look at pictures of Heifetz, etc. (3) Most people around me have never read any physics textbook cover to cover. Edward Purcell’s Berkeley Physics Series Second Volume on Electricity and Magnetism. Learning online is super easy, PLUS your boss may pay your tuition ... (That means no more forced languages or âmath for poetsâ classes). But their actual abilities (even memory) haven't actually degraded all that much. You should also get yourself a copy of Feynman’s Lectures on Physics. Generally have some experience with contour integration around singularities. This was observed in illiterate Indian women who learned how to read and write for six months. Lawyers also sound smart until you realize they write like they do intentionally to keep people from figuring them out. How you learn is much more important than your age. Getting the right material to study is only small part of it. Have you considered auditing a course at a community college? (1.5 courses) Req: Diff Eq, Calc 3, Electrodynamics: Griffiths [6]. (2+ courses) Req: Calc 1. I really believe there are no shortcuts to doing lots of problems. The mountain peak is the polar decomposition and then singular value decomposition, etc. A problem you can solve easily and quickly yields zero knowledge. Their labs are also different. I do x2 speed. There is a fairly large gap between those that just watch the lectures and those that have sat down and try to go through each and every step of the logic, and that's what everyone here (on HN) is pointing out when they similarly mention doing problems. What good is this intuition? Even if it's simply a love of mathematics itself. So if there is any distance education option that suits your needs, it might greatly augment your self-directed learning. math essentials 30s . I'm in a similar situation myself. Drilling down the practice will help with theory. Learning to code can be daunting to those of any age, but after three decades of technological absence, itâs easy to doubt your abilities entirely. YouTube is my preferred method of learning. That includes not needing to religiously solve problems in textbooks, especially the numerical ones. It also reminds me of my college days when even finding an air-conditioned room anywhere was just not possible. Get some books, and read them. It seems like the perfect use of both techniques - like Anki - but so far as I've found, nobody has done this for maths learners. The colloquia are usually very subject specific. Focus on those facts using memory techniques that work. One of the students has an introduction into what you can expect. Meanwhile you study calculus of a single variable, multivariable and vector calculus, and a little bit of ordinary differential equations, and do a year of laboratories. Once you build your intuition, you will then be in a position to "invent" the maths as you go along. To be inspired/get prepared for things to come get John Baez's Gauge-Knots_Gravity book: https://www.amazon.com/GAUGE-FIELDS-KNOTS-GRAVITY-Everything... and maybe Penrose's Road to Reality - which is like cosmology if the universe consisted of all the math and physics needed to understand all this math and physics. General relativity for those going another. Lots of prep work required for that one...). His calculus series is of similarly high quality and I would imagine his other videos are too. For me personally, understanding why it is done on a deeper level than is commonly taught helps me consolidate the concept more comprehensively and permanently. However I realized a couple of years ago that becoming fluent in LaTeX was a better option for me. Also, I should mention, one big lesson learned... Maths build on each other. How to Learn Math. Then when you are struggling working through a problem you get so frustrated. [0] https://www.amazon.com/Introduction-Graph-Theory-Dover-Mathe... Update: I also recommend keeping a journal of your progress. I'm taking hybrid online Math classes at my local community college; trying to get through all the Math requirements. To me it is beyond question that distance education is the right way for me to do this. Sounds like they are good story-tellers along with whatever else they do. Yes those videos have some nice visuals but the material is just scratching the surface. The inverse and implicit function theorems are just local, non-linear versions of what you will see with total clarity at the end of applying Gauss elimination in the linear case. (I got my Master's in Statistics that way.). People say you have to "do" math to learn it. In fact most top-paying jobs need good math skills: And Mathematics is not just numbers, it is about patterns, too! There are two approaches that work well. It's geology; time and pressure. This will serve you well in physics. fabulous website for practicing math online with answers and solutions --> at all grade levels!! I make this a separate point because it's important to spend quality time on a problem yourself before looking at the solutions. But yeah, the idea of studying in a really cold room "makes sense" to me, and this might be why. Learn it from "advanced differential equations materials". moments for almost everyone. There are recordings of the lectures on YouTube. I made a rule to complete one chapter every evening including exercises and sticked to it. Physics, and to a lesser extent maths[1], are topics where the top 1% of ability are actually concentrated at universities. There are people everywhere who will be much better than you at this stuff, and in some ways it's extremely motivating if you feel like with some hard work you can surpass some of your teachers, and it's extremely motivating when the best teachers recognize you as having more potential than the average student. Go find MIT OCWs, I'm not going to list them. Approach 2. Second, collect old text books. Think of what you're going to do with that knowledge. Your responses to the questions in the learning activities will help you to practise or review what you have just learned.
