| These are direct links to several journals. If you can link to them also through the [[https://library.oregonstate.edu/|OSU Library Proxy Server]], you will have free access to all articles (ONID login required from off campus). If you cannot access a journal through the Proxy Server, request the article through interlibrary loan. This service is paid for by your tuition and/or fees. | These are direct links to several journals.

| ===== Mathematica ===== | ===== Mathematica ===== |
| Mathematica (by Wolfram) is one of several extremely useful software programs that is useful for simple visualization of functions, computer-aided algebra, and is also a vehicle for very sophisticated programming. I highly recommend you use it for classwork, for research and for fun. As long as you are an OSU student, you are permitted a [[https://is.oregonstate.edu/service/software/mathematica|free copy for use on your own computer]]. [[http://www.physics.oregonstate.edu/~tate/COURSES/ph424/Mathematica_info.html|Here]] is a link to a page I wrote for my PH424 physics class describing how to get access, how to use Wolfram's extensive documentation and tutorials, and I added a few simple templates. | Mathematica (by Wolfram) is one of several extremely powerful software programs that is useful for simple visualization of functions, computer-aided algebra, and is also a vehicle for very sophisticated programming.

Wolfram has extensive [[http://www.wolfram.com/broadcast/c?c=86|documentation and tutorials]]. Try something very basic like "the first 10 minutes with Mathematica" - you don't need much more. |
