Mathematicians Are Chronically Lost and Confused
An anonymous reader writes "Mathematics Ph.D. student Jeremy Kun has an interesting post about how mathematicians approach doing new work and pushing back the boundaries of human knowledge. He says it's immensely important for mathematicians to be comfortable with extended periods of ignorance when working on a new topic. 'The truth is that mathematicians are chronically lost and confused. It's our natural state of being, and I mean that in a good way. ... This is something that has been bred into me after years of studying mathematics. I know how to say, “Well, I understand nothing about anything,” and then constructively answer the question, “What’s next?” Sometimes the answer is to pinpoint one very basic question I don’t understand and try to tackle that first.' He then provides some advice for people learning college level math like calculus or linear algebra: 'I suggest you don't worry too much about verifying every claim and doing every exercise. If it takes you more than 5 or 10 minutes to verify a "trivial" claim in the text, then you can accept it and move on. ... But more often than not you'll find that by the time you revisit a problem you've literally grown so much (mathematically) that it's trivial. What's much more useful is recording what the deep insights are, and storing them for recollection later.'"
I was the best mathematician in my university math classes. Who knew?
Sounds like learning is not necessarily a linear process. Makes me feel better about my learning experience!
Now to learn what the question is...
Everything, and only things, that math people do is "trivial".
Fuck systemd. Fuck Redhat. Fuck Soylent, too. Wait, scratch the last one.
All too often I've encountered math teachers who failed to properly explain advanced mathematical concepts because to them it was obvious and trivial.
Gee, thanks.
There are two types of theorems: trivial and unproven.

While I agree that one shouldn't waste time questioning every statement you encounter, there's a very ancient and useful tradition in math pedagogy that emphasizes these sorts of things. See, for example, gradually building up geometrical theorems from a few axioms, a la Euclid.
Often, the process of working out complex proofs for yourself is crucial to understanding why things work, not to mention developing and practicing logic skills that are essential in math and elsewhere.
I'm not saying one should waste time trying every exercise or redoing every proof, but some of my greatest insights into the inner workings on math have come from exercises that took me a couple hours to work out or textbook passages I went over a number of times and really dug into how the details worked. If I skipped everything I couldn't do in 5-10 minutes, I doubt I'd ever have developed the more advanced skills and intuitions that would be necessary to see why some results are "trivial."
We must all learn to exist in that exquisitely uncomfortable place where everything we know is always up for reassessment. Otherwise, we miss change, and change is the only constant.
i had to be woken up at around 9:20am for a 3 hour A-Level Maths exam that had started at 9am and was to end at 12. starting at around 9:25 on the first question, after around 25 minutes i gave up and went onto the 2nd question. this one i did in around 15 minutes. from there i accelerated, completed *every* question, returned to the first and completed it in a few minutes. i then sat back for a while, then got some coloured pens and coloured in one of the graphs. i might even have been bold enough to have left 10 or 15 minute early.
when the results were in i learned i'd got an A. on an exam that was supposed to be 3 hours and i'd completed every question in a little over 2. that was 1987 and i've never forgotten what happened. the point is: i know that once you get started, and get into the mindset, anything is possible: questions you couldn't answer suddenly become easy.
I think the "lost and confused" applies to both...

I'm a physics graduate student, and while I'm not quite in the same boat as the mathematicians, I'm familiar with the problem. You spend a lot of time trying and failing to figure out what's going on. You have to be comfortable with not knowing things you want to know. I think that's a really useful ability because you don't demand easily digestible answers for everything. Such answers rarely exist, although many people seek them from short articles and soundbites.
It think it also has larger philosophical implications.. Forgive me for bringing up religion, but most (albeit not an overwhelming majority of) physicists do not believe in any higher power. If you're comfortable with not knowing things, then the answers provided by belief in a higher power doesn't provide additional comfort. You have no need for that hypothesis. (I'm not saying that people like religion simply because it provides easily digestible answers -- although religious groups *cough* young earth creationists *cough* certainly go for that. Many religious Jews spend their lives studying and debating the meaning of the bible; it's anything but easily digestible.)
Never trust the one who has the answers. The politician. The Preacher. The grammar school teacher. Seek those who have questions.
I'm a writer and inventor, I hope to come to understand things with my writing. I may draw a concept in an attempt to understand it better. I have written programs to unravel mysteries (you've seen the 'game of life'?) I try to reserve judgement when presented with an obvious 'truth' on Slashdot (as most of you do !).
Here's my email sig, feel free to share it:

If this is how things stand, then the Philosophy of Mathematics to date is a catastrophic failure. When there is no better methodology than "fumble around in the dark a bit until suddenly you're convinced" then the project of attempting to guide students in understanding maths has done no work at all.
Is this the fault of the philosophers or the mathematicians? I'm inclined to think that the philosophers have at least failed in their advocacy, if not in their actual subject.
Myu:
I don't see what is so special about mathematicians skimming over stuff and not sweating the small stuff. Many project planning meetings we treat lots of stuff as black boxes and proceed with some simple assurance that it would do what the team says it will do. The post processing guy would have a very nebulous idea of the geometry core team's claims. Nobody understands what the mesh maker says anyway. Then there are the mathematicians from the solver group. Upside down triangles, dots crosses some time three integral signs lined up like sails of some old ship .. Eventually we understand enough of it to make it work most of the time. Even after the project is done and the feature has been shipped and the user story has been marked complete and independently verified by the user proxy, nobody understands how the mesher meshed it nor how the solver solved it.

And yet, according to your other postings you're quite a nutcase...

Some similar effects occur with engineering and programming. For instance:
An engineer is ALWAYS working on something that's broken. That's because, when he gets it fixed, he moves on to the next thing that's broken. (It's like the thing you're searching for always being in the last place you look. It's not Murphy's law, It's becaue, when you find it, you stop looking.)
A good programmer doesn't come to a problem with all he needs to solve it. Instead he comes to it with a big toolbox, SOME domain knowledge, and the skills needed to learn the rest during the project. This will be mostly stuff related to the project, but may include more programming tools as well.
Designing/architecting a program or system is like handling a black bag with the solution inside, in the form of blocks connected by strings. You squeeze it around until you get it into two lumps with very little string running through the thin neck. Then you it into two bags and document all the strings that went through the cut. Repeat unti the bags are small enough to understand easilyj and keep the entire explanation in your head. (In the case of a program that means the code itself fits on a page, with over half of the page being comments.) Then you can open the little bags and grok each one - which by now will be either trivial or maybe embody a single deep concept or "neat hack". (But avoid "neat hacks" if they're not obvious or if something straightforward does the job just fine.)
A good programmer might know the exact solution immediately upon seeing the problem. It could have been something they've solved many times before. There are times when I'm quite bored implementing solutions, because they are the same (general) solutions I've implemented many times before.
Programming is really *nothing* like math, in my opinion. Programming is nearly always *pragmatic* in nature. Many mathematicians study things with no obvious practical application. Programming is answering the question: "how?". Math is answering the question "what is?".
There is nothing like teaching a topic to force you to learn it.

Cute headline, anon, but it's kinda misleading and reeks of BuzzFeed's desperate "read me!" attempts.
Becoming a mathematician is like becoming someone who is fascinated in shoes, or briefcases or watches or hammers.
An important class of people inordinately fascinated by shoes, briefcases, watches, and hammers are manufacturers.

Ceci n'est pas une Signature !
Felt much the same throughout my sojourn as a doctoral candidate in Electrical Engineering.
Had a professor in college who taught only 1 class for the semester. After that, he assigned topics to each student in the class with a few suggested areas to starting researching their topic.
Then every class for the rest of the semester consisted of students going up and presenting their findings, while the professor questioned them to guide their presentation to key areas, and clarified/corrected/expanded on their presentation as needed to ensure the audience gets the information they need for the exams.
This. class. was. awesome!
Being given responsibility to dive into a topic on your own, and having to develop enough understanding to present it to others was a huge breath of fresh air and a ton of fun. Very satisfying to go up there and nail the answers to everyone's questions. It also prepped students on how to handle public speaking, beyond the simple 15 minute memorized presentations you'd give in highschoool, but actually teaching a class for an hour.
"Guess and go" -- the modern teaching technique. Not in a good way. This is seriously what they are teaching kids today.
I'm not sure why the word "teaching" is still used. That movie title comes to mind: "I Can Do Bad All by Myself" -- interesting that both movies with that title on IMDB are rated in the 3's.
They don't teach phonetics. Kids in middle school don't even know how to do long division. WTF.
FWIW, I am not big at being able to derive things. My idea of studying is to work through the problems. If I don't understand a group of them, THEN I dig back into the theory.
I come here for the love
Therefore, you have to be a nutcase to get an A in nonlinear differential equations.
I took some classes that way, and it worked well. Except for the chapter on business uses of artificial neural networks, which went to a woman fresh form Mainland China. That did teach me that there are some pretty sophisticated concepts that most of us in the US think just natural.
