Mathematics

The Concise Oxford Dictionary of Mathematics gives brief definitions of most mathematical terms.

The Princeton Companion to Mathematics gives fairly full explanations for most mathematical concepts.

The World of Mathematics is another encyclopedia with full explanations of mathematical concepts. Many of the concepts have graphic illustrations, e.g., prime spiral.

The Complete Dictionary of Scientific Biography gives biographical information on important scientists from antiquity to the present. It also gives bibliographical references to more extensive treatments for these scientists.

The Mathematical Atlas offers a visual view of the topics and subtopics of mathematics. It is helpful in understanding the Mathematics Subject Classification used by MATHSCINET and ZENTRALBLATT MATH. Mathematical Atlas also directs the reader to special software and websites. See for instance “Fourier analysis.”

Mudd Math Fun Facts teaches math principles with games and puzzles. A good source for lower level math teahers.

Full-text of over 400 e-books in applied mathematics. The web site can be confusing. When you click on a title and chapter, you get only an excerpt for that chapter. To get the full e-text it is necessary to click on the PDF symbol. The “Find it at Purdue” option may also be misleading. The Purdue Libraries should have every SIAM e-book.

Besides giving functions, Wolfram uses “Mathematica” to plot the functions.

These are math functions provided by the National Institute of Standards and Technology.
