learning math in your 30s

Start at the beginning. Covered for linear algebra? Often times what happens is that highly technical topics such as those you mentioned look attractive from the outside but get painfully dry, boring and difficult once you pick up a text book and start studying from it. ... it has a new chance at life in your 30s. Amazingly flexible: Learning to read in your 30s profoundly transforms the brain Date: May 24, 2017 Source: Max Planck Institute for Psycholinguistics Coding is becoming a skill similar to reading. There are a vast number of interconnected details that have the potential to be wrong and far fewer automated ways to catch any errors. https://gumroad.com/l/noBSLA. It has chapters with names such as calculus on manifolds, hypercomplex numbers, the entangled quantum world, gravity's role in quantum state reduction etc which sound pretty deep and complex for a recreational learner. A lot of learning in physics comprises paring down your misconceptions until the correct methodology, often surprisingly simple, appears. Often, what turns people off is that they do not get things quickly (e.g. Get a good textbook on subject of interest, start reading, start scribbling, start answering the questions. 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/. Go find MIT OCWs, I'm not going to list them. In fact, with hard work and commitment, anybody can muster them to a high level. I've had the same thoughts about (re-)learning some math. This is a point made multiple times in those very videos. Cloud shapes? In that case you're in luck. Grab three.js, and then once you've followed some tutorial somewhere to get a triangle on the screen, start doing things, but do them manually, including implementing matrix multiplication yourself. If you long for maths; it's likely it'll conceptually take you places you won't go without it. Learning to code can be daunting to those of any age, but after three decades of technological absence, it’s easy to doubt your abilities entirely. I've posted a full undergraduate curriculum based on free resources here: If you don't have the patience for doing random math problems and just want to understand things abstractly, try this channel: I learned Calculus myself through a book called "Calculus - an intuitive and physical approach", by Morris Kline. This is my conclusion, 1. When you can throw away all the books (the knowledges are all online anyway), you are learned. Learning programming in my 30s I majored in something completely unrelated to CS, but I recently have discovered a severe interest for it and really want to get into a career in programming. algebra II? 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. I'm not sure if they're complete or not, but there's a good bit there. You guessed it! I would suggest getting text books with loads of homework problems with solutions and actually sit down to work through the problems. People who try to understand math by reading alone (or by watching videos) tend to fail in real life -- they tend to be able to recite definitions but their ability to execute on their knowledge is weak. (2+ courses) Req: Calc 1. Depending on your background, you could just pick up a popular math book to get excited about it, or find a free online textbook at your level and dig in. Another thing to ask yourself is, what will I gain from this? Instead they are getting the gradient of a surface, NOT the function, as the change the coordinates of the surface. It's hard, but definitely doable. Reading, Massachusetts, Now here is a very, very, important point. For maths, books like Prime Obsession by John Derbyshire, e The story of a Number by Eli Moar, Number by Tobias Dantzig, The Unknown Quantity by John Derbyshire provide good orientation for number theory, analysis & calculus and algebra. But, if someone can continue to learn math their whole lives, it must not be impossible to start. Every one of us sits at a desk with a powerful internet-connected computer. So, you need not follow a pattern that is made for late teen students attending university. Read it, think about it, read again, write it down or sketch it out, and then use it (by answering questions), that all helps to get the ideas into your mind. Includes chapters on sets, graphs, calculus, linear algebra, and more! You can get his book, or even better, watch his large amount of lectures: Get a real pen and paper, get a real physical book, sit and solve problems with pen and paper for hours every day for a few months. I think I understand what you're saying -- one needs more than just cool videos and cool intuition. But there is a certain extent to which they like to work by building things on a frictionless ice world, and get uncomfortable if asked to build something on the rough ground of the real world. I'm the same. I do not know what options you have in that regard, but if being enrolled in a programme does not seem off-putting to you, it might be worth checking out. > 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. Take refresher classes at community college. So first, find your love of physics. The book covered some Calc 3 too so continued being useful. A hot room sounds horrible, but the memories of college days does make sense to me. I'm doing my OU Masters in Maths now, in my 40s. I elaborate on the method in my response. But their actual abilities (even memory) haven't actually degraded all that much. Good. You should also get yourself a copy of Feynman’s Lectures on Physics. I used E. Nearing, student of Artin at Princeton. You might also look at books like God Created the Integers by Hawking, The Calculus Gallery by William Dunham that curate interesting and historically important results, where original works are often reproduced. BlackPenRedPen[10]: Fantastic teacher. Anticipate questions taking you six hours to solve, leaving your table and floor strewn with the history of your consciousness. It is more important to know the ideas than to remember the formulas. How you learn is much more important than your age. Then, of course, go for P. Halmos, Finite Dimensional Vector Spaces, grand stuff, written as an introduction to Hilbert space theory at the knee of von Neumann. It's geology; time and pressure. There, relax any desire for really careful proofs; really careful proofs with high generality are too hard, and the generality is nearly never even relevant in applications so far. It takes time. When you learn the basics of modern physics you will automatically get a good understanding of lots of important math topics plus you will always automatically know why they are important. It's not just linear algebra, 3blue1brown also has an entire series on undergraduate calculus, and series on Statistics, Linear Algebra II and Group Theory are in the works. 3. Three or four days a week, two to six hours a day, grind grind grind GRIND GRIND GRIND GRIND. I was lucky to have a great foundational math background in highschool, my calc 1/2 teacher was considered one of the best in my state. They are generally open to all, and will start to get you up to date on what's new across all of math/physics. While true, a skill that is not emphasized enough is learning (by heart) and understanding definitions. It's an introduction to mathematics from a programmer's standpoint, with a big focus on taste and that second level of intuition beyond rote manipulation and memorization. It's all about doing it like we did in high school. 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. Warning. In cold parts of the world, warm has connotations of comfort, not cold... Is this part of the process? For more, get into numerical methods and applications. If you're bright, motivated and take ownership of your own learning, the faculty will love interacting with you. The recent ones are less "textbook." One text (Wangsness E&M maybe) had a great student quote, roughly “I understand the principles but I can’t do the problems.”. Doing the same thing with math, physics, engineering, etc will result in the same increase in talent. Lawyers also sound smart until you realize they write like they do intentionally to keep people from figuring them out. Home Math 9 Math 10C Math 20-1 Math 30-1 Math 10-3 Math 30-3 Physics 20 Physics 30 ... Powered by Create your own unique website with customizable templates. Calculus of variations: Nail down cold how to derive the Euler Lagrange Equations for a functional. I wanted to build things. Modern graphics has moved so far up the stack nowadays that you probably shouldn't say that you "know 3D graphics" after that exercise, because you'll know 3D graphics circa 1995. A lot of resources on the awesome github: If you want to be serious about math you should get a feel for what mathematics means to mathematicians. (Man in the magnet, flip the sign of a term in your potential to get a mexican hat, see that the ground state is now different etc.). Mathematics is beautiful. Using it is so important! This is a long-term project, so I'd recommend by starting a bit with "learning about learning". Commonly given to physics students as their source on Hilbert space for quantum mechanics. In my 20's I used to love picking things up just for the. They are in my home library and I try to flip through some of them once a year. In the blind alleys. Chunk your learning and use your little victories to drive you (brain hack: humans are a sucker for little victories). That includes not needing to religiously solve problems in textbooks, especially the numerical ones. My advice would be find a cheap university nearby and start enrolling in courses. (8) Counterintuitive: If you get completely stuck, move on! Regardless, I'll give my two cents for textbooks anyway. Anticipate that watching youtube is not a substitute. For maths, I recommend Mathematical Circles: Full of fun discrete math problems. Further, you wouldn't even need textbooks. I find it almost comical at this point. Keep up a lifetime of learning! You will also gain a lot of the pre-req's for optimization and constraint solving. Essential Math 30S Geography 20F Rugby and Dragon Boat Contact Me Formula Booklet. When you return in a few days/weeks, things will almost certainly be clearer. I'm glad we have it. In addition to those reasons, the other hugely important one is that my notes are now in git, I can grep them, and they don't add to the pile of objects that must be dealt with when moving to a new home. When it comes to friends, it really is about quality over quantity. I made a rule to complete one chapter every evening including exercises and sticked to it. ;). To be able to build my own machines I have to learn some physics and other branches of mathematics and that's what I have been doing for the past months. Actually, might laugh at linear algebra done over finite fields, but the laughter is not really justified: E.g., algebraic coding theory, e.g., R. Hamming, used finite fields. (5) Be prepared that the timescales in physics are long. Use many sources. For physics, my goto book (which I have never finished) would be The Road To Reality by Roger Penrose. These days, with the availability of opencoursewares, you can simply watch a few lectures before deciding if its worth your time delving deep into the topics with a textbook. There's a lot of boring drills before it gets particularly interesting. For this purpose, well regarded popular science books should be your first choice. But I disagree entirely on this approach to learning fundamentals of math and physics. Lucky for me, I come from the German-speaking realm, where there is a distance learning university that offers a solid BSc programme in mathematics at roughly one eighth of what someone would pay for tuition in the UK. After 3-4 such pieces, get an hour of piano instruction and continue on. Assuming one has continued to pursue learning, someone in their 30s would have built up a significant enough semantic tree to pin new knowledge to. I find it impossible to think or stay focused in a hot or even warm environment. 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. See Lanczos "Calculus of Variations" (Dover Books) to sort out your initial questions and learn the smooth little trick with integration by parts. All the code is open, so you can learn from it. also, they will teach you the necessary abstraction - the first thing standing in my way of a degree in physics was my intuition and need to picture stuff. Every topic seems to have a few really good books like this one, and there are often books that will take a totally different approach, like H Jerome Keisler's nonstandard calculus book using infinitesimals. I follow a bunch of folks on the internet and idolize them for their multifaceted personalities - be it math, programming/problem solving, physics, music etc. Have you tried putting anything out for others to consume? However, if you’re letting your age stop you from learning and making the career switch, you’re thinking in a very narrow-minded way about what learning to code could do for you. Work through a famous text of freshman physics and then one or more of the relatively elementary books on E&M and Maxwell's equations. But not all videos are slow. I never really studied physics, but I found the first books from the "Feynman lectures on Physics" to be very good. If you have to, solve the conceptual ones. So don't think "I read 2 pages today", instead think "I understand graphs better now". I guarantee that you see them as much more intelligent people than they are or think of (not dissing on them, but we tend to put these people on pedestals and this is a big contributor to Imposter Syndrome. First up, I am no expert, but I have traveled this road for a while so I'll share a bit. So this is my number one suggestion. For calculus and linear algebra I'd go with Khan Academy, especially since it seems like all you need is a refresher for calculus. The second book might be tough to finish as its really really deep for a thin book. For physics, I believe you fall in Leonard Susskind's target audience. As far as books, I can recommend Schaums Outlines for good examples of worked-through example problems. Maybe you could make a sketch (as shown below), H. Sigmundsson, R. C. J. Polman, and H. LorÃ¥s (2013). (5) Finding someone to talk to is really useful. (learning rate != thinking rate / creation rate!!). ML will touch on linear algebra, calculus, probabilities/statistics, etc. It’s better to start with books that are “too easy” than those that are “too hard” (for your level, whatever that is). If you can do all the odd problems in this two volume set, you are an educated person, regardless of your greater aspirations. Check out this video as an intro to GR: Great post. They teach mathematics in small chunks with practice. I feel like I'm getting tired of being a software engineer (defense contractor) at a small company and looking for something higher level. For best results you need to make a nice LaTeX set up. Approach 1. I'm looking to (re)learn the following - calculus, linear algebra, constraint solving, optimization problems, graph theory, discrete math and slowly gain knowledge and expertise to appreciate theoretical physics, astrophysics, string theory etc. I learned the more advanced maths I use daily in my thirties. See the website for how that works. I'm learning Japanese at 35 with the goal of becoming business-fluent in five years. I didn't realize this was unusual and thought I got very bad at learning. Printing Instructions: The charts above are available for viewing and printing as 11" x 17". Calculus by Spivak is a great example, it straddles the line between calculus-in-college and analysis. The same person wrote a book for linear algebra as well but I have not read it: If you're doing it to learn, don't sweat about the prestige of the place. Edward Purcell’s Berkeley Physics Series Second Volume on Electricity and Magnetism. > If the textbook is in its 4th printing or so, the answers are correct. I decided to be very systematic about it. (Lemme know if you have more ideas) Conclusions: Blinders, your insights have been realllly valuable. Anki is a very good memorization tool, I would use it aggressively. What topics are you most interested in? (learning rate != thinking rate / creation rate!!) This will expose you to cutting edge research going on. 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. For calculus of several variables and vector analysis, I strongly recommend, Tom M.\ Apostol, Linear Algebra (text book link: https://www.amazon.com/exec/obidos/ASIN/0980232716/ref=as_at...) Think of parameterizing a surface instead of a curve and see how a tangent bundle describes a whole new vector space - one vector space for every point in the manifold. I don't have a good level 2 book, but that would mean looking into coordinate transformations, QR decomposition, and some more stuff. The (my) short answer is grind. The first order necessary condition for an extreme point is that the derivative of the function be zero. It is very different than the practical engineering-focused math I learned in school. I can't stress enough that you should watch him. I have been reading several text books as well for practice and reinforcement. That is a fantastic place to start. Your mind is an amazing and unique tool, and you want to use it the best way you know how. Also see Griffeths E&M book for a great explanation of Fourier's trick and separation of variables in the chapter on special techniques... At least in the 1999 Third edition. Honorable mentions: 3Blue1Brown[11], Numberphile[12], Veritasium[13], StandUpMaths[14], SmarterEveryDay[15]. My learning actually accelerated in my 30s because knowledge pays compound interest -- the more knowledge you have, the faster it is to acquire new knowledge. Just remember that. Even if it's simply a love of mathematics itself. How I learned to code in my 30s. One final warning. Don't just follow the steps you are shown, try your own ideas! 21- … This inspired me to get some more textbooks and try to go through them. Bird lifecycles? Are you more interested in math or physics? If the textbook is in its 4th printing or so, the answers are correct. A final thing: it's really worth doing. Decide if you want to learn physics or applied mathematics. Halliday & Resnick (or one of its later updates from Crane) is a better bet in this regard. or internal drive that provides them the impetus. > Halliday and Resnick, early editions , printed in the late 60s and 70s.
