Since its first printing in 1964, Abramowitz and Stegun's <a href="http://www.math.sfu.ca/~cbm/aands/">Handbook of Mathematical Functions</a> has been a standard (and public domain) reference manual for special functions and applied mathematics. This week, NIST released its successor, the <a href="http://dlmf.nist.gov/">Digital Library of Mathematical Functions</a>, online to the public.post:www.metafilter.com,2010:site.91911Thu, 13 May 2010 13:31:59 -0800Upton O'GoodmathmathsmathematicsappliedmathappliedmathematicsabramowitzstegunabramowitzandstegunhandbookhandbookofmathematicalfunctiondlmffunctionsspecialfunctionsdigitallibrarymathematicalfunctionsnistBy: Philosopher Dirtbike

Awesome. Abromowitz and Stegun has been a handy reference for me for years.comment:www.metafilter.com,2010:site.91911-3087960Thu, 13 May 2010 13:34:33 -0800Philosopher DirtbikeBy: lukemeister

According to Google scholar, A&S has 45543 citations. That's gotta be some kind of record. Of course, that's what it's for. You're writing an article and you take some equation as a given, thinking to yourself "Everybody knows this... no point in finding a reference." That's when you stop, reconsider, and open up A&S.comment:www.metafilter.com,2010:site.91911-3088107Thu, 13 May 2010 15:03:21 -0800rlkBy: ZenMasterThis

Buy one anyway - the Dover edition is dirt cheap and has many uses the on-line library doesn't cover, such as self-defence or emergency heat production.comment:www.metafilter.com,2010:site.91911-3088154Thu, 13 May 2010 15:50:10 -0800Dr DracatorBy: madcaptenor

DU, I kind of find MathWorld to be more idiosyncratic and biased towards "recreational" mathematics than A&S.comment:www.metafilter.com,2010:site.91911-3088179Thu, 13 May 2010 16:13:28 -0800madcaptenorBy: DU

As a nonmathematician, most of my enjoyment of this comes from the appearance of the page before the images representing the equations have finished loading, and reading
<blockquote>With _____ the spheroidal wave functions ______ are solutions of _____ which are bounded on _____ or equivalently _____ which are of the form _____ where is an entire function of _____ . These solutions exist only for eigenvalues _____ of the parameter _____.</blockquote>which in honesty approximates my level of comprehension even after the equations have shown up.
Even so: awesome.comment:www.metafilter.com,2010:site.91911-3088218Thu, 13 May 2010 17:11:06 -0800ookBy: Lemurrhea

The problem with this:
Now I want to pull out my trusty <a href="http://books.google.ca/books?id=1pQcxFYke6kC&printsec=frontcover&dq=number+theory+iv&source=bl&ots=7LwuUeRzvO&sig=_5lJAPiO38-UjIHEy3xdKAMpXXI&hl=en&ei=t6LsS5u1N4O0lQeaw8y1CA&sa=X&oi=book_result&ct=result&resnum=1&ved=0CBQQ6AEwAA#v=onepage&q&f=false">Number Theory IV</a><sup>1</sup> and try to learn from it (third time's the charm) instead of reading about law, as is my actual job. Thanks a lot, jerkwad.
<small>No, seriously, thanks a lot, this is a fantastic resource.

Spotted in the bookstore last month: a woman asking the clerk for a book on "algebra" for her son who was doing his GCSEs (so he was 15-16) and getting handed a 900 page Dover book, Introduction to Abstract Algebra. My sense of civic duty overcame my math lulz impulse and I intervened.
Maybe for his A-levels she can buy him Spivak's Calculus.comment:www.metafilter.com,2010:site.91911-3088631Thu, 13 May 2010 23:21:52 -0800atrazineBy: kmz

Heh. yes, I've confused many when talking about how difficult I found Algebra II. Slightly different things when you're talking about Abstract Algebra instead of high school Algebra.
Another fun "simple" subject: I've seen advanced combinatorics texts where the chapters were all labeled something like: "Counting", "Advanced Counting", etc.comment:www.metafilter.com,2010:site.91911-3089187Fri, 14 May 2010 09:44:57 -0800kmzBy: DU

idiopath: Nope, didn't notice the Republican elephant. It's a website put together by SIAM, and they do <a href="http://www.siam.org/about/science/sci-agencies.php">applied maths for the U.S. military</a>. I had just been saving this link for a math post, 'cause I think math is neat and they do, too, and there's other things one can do with it than what they use it for (as shown in that "why do math" website). Hope it wasn't too much of a tangent....comment:www.metafilter.com,2010:site.91911-3089841Fri, 14 May 2010 14:05:39 -0800aniolaBy: Crabby Appleton
