Catenary. A hanging chain with short links forms a catenary.
Freely-hanging transmission lines also form catenaries. The silk on a spider's web forming multiple elastic catenaries. In physics and geometry, a catenary[p] is the curve that an idealized hanging chain or cable assumes under its own weight when supported only at its ends. The curve has a U-like shape, superficially similar in appearance to a parabola, but it is not a parabola: it is a (scaled, rotated) graph of the hyperbolic cosine. Undergraduate Mathematics Majors.

Applying to Graduate School offers some helpful links. Find a Graduate Program, explore graduate programs in the mathematical sciences - search and sort by specialties, requirements, masters or PhD, size, location (U.S. & Canada). Graduate School Fair at the January Meeting Mathematical Sciences Graduate Programs in the U.S. is a list based on overall rankings, taken from survey groupings. Current Employment Trends in the Mathematical Sciences an article for math majors who are considering graduate school (at the beginning of the Assistantships and Graduate Fellowships book) NSF Graduate Research Fellowships support individuals in the early years of a Ph.D. program. MCM: The Mathematical Contest in Modeling. Study Mathematics in Hungary - Budapest Semesters in Mathematics. Math in Moscow. Hertz Foundation Fellowships. What’s new. Advice. John Baez March 25, 2007 I have reached the stage where young mathematicians and physicists sometimes ask me for advice.
Here is my advice. Most of it applies to grad students and postdocs in any branch of science who seek an academic career involving research. The stuff on giving good talks will be helpful to almost all scientists, since most give pretty bad talks. Mathematics on the Web: Books. This page lists some sources for books on the Web.
There are a few electronic books already available, but the primary sources remain the publishers whether fully commercial or university publishers; in addition, book dealers can provide out-of-print and antiquarian material. Of course, libraries are the most important resource for the literature of mathematics. Directories of books available on the Internet Electronic Books Online Proceedings Electronic Series Individual Titles. MathWorks - MATLAB and Simulink for Technical Computing. Career Information.

This area contains information and links to numerous Internet resources, which could be used for teaching and learning of calculus. If you would like to suggest adding information to this area, or have comments or questions, please contact Przemyslaw Bogacki, the calculus moderator. Here is the contents of the Calculus Resources On-line area: Mathematics Archives software collection contains numerous shareware and freeware programs useful for teaching and learning of calculus. In addition to the "calculus" directories in the Mac and Windows/MS-DOS areas, interesting programs may be found elsewhere (e.g., in the directories "Advanced Calculus", "Graphing Programs", etc.). Various other areas of the Math Archives also include links and materials relevant to calculus, e.g.

This book is an introduction to the standard methods of proving mathematical theorems.
It has been approved by the American Institute of Mathematics' Open Textbook Initiative. Also see the Mathematical Association of America Math DL review (of the 1st edition), and the Amazon reviews. The second edition is identical to the first edition, except some mistakes have been corrected, new exercises have been added, and Chapter 13 has been extended.
(The Cantor-Bernstein-Schröeder theorem has been added.) The two editions can be used interchangeably, except for the last few pages of Chapter 13. Order a copy from Amazon or Barnes & Noble for $13.75 or download a pdf for free here.
