I'm a frequent user of Math SE and I've been working to understand something for the past week that I really struggled with. What's more is that I wasn't able to find a good thread on Math SE on this topic, and so I had to look through several textbooks and resources before getting a good grip on this. Is there any way for me to create a thread on Math SE for this, which might be helpful to students who're in the same position I was in? Is the best way to do this asking a question myself and then answering it, or is there a way to create a thread with just write-ups on topics (that people might find helpful) as well, not in answer to a particular question?

I might want to answer my own question because:  I arrived at a solution before there were any other correct answers or I like mine better, can I still answer my own question?  I have a folder with lists of code snippets for things I always forget or get wrong, such as regular expressions for processing XML, common WinForms control idioms, etc. Is it considered poor etiquette for Stack Overflow to ask a question I already know the answer to, and then self answer, just so it gets recorded on the website?

Is it possible to get into algebraic geometry by just knowing calculus and linear algebra or is this too far of a stretch?  If not could anyone give me a list of book/lecture notes recommendations in chronological order to dive into algebraic geometry with my state of knowledge?  Thanks

Can someone recommend a good basic book on Geometry?  Let me be more specific on what I am looking for.  I'd like a book that starts with Euclid's definitions and postulates and goes on from there to prove thereoms about triangles, circles and other plane shapes.  I'm not interested (at this time) in a book that ties geometry in with linear algebra or explains non-euclidean geometry.  All the books I've seen seem to be of two types 1) Let us use linear algebra and other techniques to put geometry on a firm footing. Let us assume you already know Eucliean geometry and move on to more interesting stuff. These are probably too advanced for me. 2) Let us skip all that complicated postulates/proofs and make geometry fun.  Too easy.  When I was in 9th grade Honors Geometry way back in 1981/82 we had a textbook that, as I recall through my foggy memory, was very good and did systematically build up geometry from the propositions (5 of them?).  And it certainly didn't attempt to address Hilbert's contributions to geometry or explain non-Euclidean geometry. Unfortunately, I don't recall the title or author.  I suspect the book was used nationally though and for quite a number of years, so perhaps someone with a better memory than me can provide a title/author.  I do recall it had all the postulates and most major thereoms listed at the end of the book.  My motivation is two fold... 1.  Review the material myself in preparation for my advanced texts. 2.  Help my children in a few years when they take geometry.    Books I could get for the iPad/Kindle or free books (Google?) would be most appreciatied, but I'm not opposed to killing a tree either :) Thanks for all the help. Dave

There's a great thing, stack exchange application (I'm using it's version for iOS). However, it has bugs so I want to know - is it correct to create threads for bug-reports on meta site? SE application isn't part of web-environment, so I doubt. Same question about feature-requests.   If it's not a good idea to create bug reports/feature requests for SE application here, then where that should be asked?

SO has helped me so much in times of need. It is crazy - sometimes I am having a huge issue with a program I'm working on at school or work, and I post it on SO and the answers come quickly and easily. Lots of time it's a typo, while others it's a deep misunderstanding of mine. I wonder how I can fit in here at Stack Overflow. How I can contribute. In fact, I feel such a “beginner”, I don't even know where to look half the time. But I see there is now a place for /Programmers/ which leads me to wonder if there can be a site for beginners - and strictly beginners. Beginners post in Stack Overflow, and only beginners can post answers. Meaning, you must ask a question in the beginners forum in order to answer one. Or something, I'm not sure, I just want a place to connect with others who are just starting out how to learn about programming, and want to get the chance to answer other beginner questions so I can learn more (you learn 40% of what you do and 90% of what you teach). What do you all think about this?

Regarding , made by me, and general questions in this matter. I did receive decent answers on the question that was asked, but it wasn't asked clear enough by me I now see. I do not want to invalidate the answers by completely restructuring the question. Should one post a new question ignoring the other? or Should one refer to their old post and writing a short &quot;because x I reposted this...&quot;?

Which of the two books is suited for a student looking to learn how to write proofs? I have a working knowledge of calculus and linear algebra but I'm not good at writing proofs. My intention is to learn proofs in general, not necessarily for the two.       The reason I ask is that the latter is suggested on a highly voted question here but the former has a more apt name. The reviews aren't helping. Please don't suggest books other than these.

I'm trying to find good books on the history of mathematics, dating as far back as possible.  There was a similar question here , but mostly pertaining to Philosophy, and there were no good recommendations on books relating specifically to Math History.

I guess not, but just in case it's easily fixed: could the hot questions and SE profile support MathJax to render question titles and summaries? On most SE sites, the SE MultiCollider does not support MathJax, and  the global SE profiles:   Of course, the specific site itself supports  just fine:   I know support for this on the regular sites , &quot;as it is an extremely heavy dependency&quot;. But maybe it's still doable just for rendering the titles and summaries? Or maybe only on the global SE profile? (Careers might like this too? Never used that.)

My feed shows questions from all SE sites, most of which are irrelevant to me.  I'm interested in physics, math, and programming, topics I find served well by the SE model.  There are many SE communities I have no interest in and even get annoyed when I see the kinds of questions and answers posted (ie, opinion based answers that are passed off as truths).    It would be much better if I could manually add each site I'd like to see questions from.

I'm in mathematics, though I don't know if the answers to this will be field-dependent. There have been previous good questions that answer what to ask graduate students  and only somewhat relatedly  (about what to ask students of potential advisors). However, I don't know what good questions are to ask professors themselves. The big question is, of course, "will I be happy at this school?", but it's not clear to me what the 'right questions' are to help me get a feel for this.   Essentially, what should I know about the program/school that are suitable questions to ask a professor during a meeting at these visit days?

Is SE Q&amp;A format relevant for "identification of seldom physical objects observed in real world"?  Questions like "I do not know function of this object (picture) - which purpose does it have?"  In many cases I suppose these question could have civil engineering or handcraft i.e. cultural/historical background. In second case "SE history" might be okay. For first case, I do not know.

I am a high school math teacher who likes to understand the development and rationale behind formulas, albeit I am not a math expert by any means.  Could I get some help in trying to explain how the formaula for the sum of a finite geometric series actually can be derived?  I need a a rather simple explanation initially, so that I can grasp the essential nature of the formula.  Thanks for allowing me some space here.

I have read many questions asked in SEs I have not joined yet; the sidebar advertises new hot questions and the top questions of many SEs are worth reading.  Whenever I read an really awesome answer (or a question) on such a SE site, I wonder whether I should join the SE just in order to upvote the answer (or the question, respectively). I know my behavior will have only a minor impact on SE sites, but I look for a general policy which is, in some way, good for SE if followed by all persons who are in such situation.  Is there any such policy? Or should I just do not care about voting and do whatever feels right at the moment. (In the past I have both joined the SE site and simply ignored the upvote button.)

Is there a specific area for new users that are new to coding where they can go and ask questions without being blocked for asking a question they may not have the answer to or isn't sure how to correctly ask a question. I know that there is a section for FAQ to try to explain how to ask a good question but for people who are learning and want to get the opinions of experienced coders, it can be hard to come here and ask a question. So again, is there a community that is open to helping new coders that may not always know how to ask the question they are trying to get an answer to?

I've recently run into many questions where to author asks several related questions in one post, many of them asked before.   I'm wondering what out policy is on such questions:   Should I vote-close them as being not constructive? Should I vote-close them as duplicates? Should I leave them be? Or even suggest an answer?    - Each of the questions: Waiting for an AJAX request with selenium, and headless browsing in selenium have been asked here before, but he asked both in one.  I've done my best to search for similar questions here in meta but I was unable to find any, reading appreciated.

I don't know how new Stack Exchange sites get opened. I've found some of the new SE sites to be very useless. There are many different and important subjects that are not being addressed by any SE site. I strongly suggest creating a new SE site about unscientific psychology. I have come across many questions that are related to human problems that I would like to ask on an SE site.  How do new SE sites get opened up? Is there a place for voting up new SE sites?
