I wanted to recommend a few programs that I have found useful for Engineering classes on a Macintosh system because there seems to be very little information posted about this. I am very proficient in Windows and Linux but ever since I got my Powerbook I haven't been using any other computers. Anyway, I have found the following apps helpful: Maple 9.5 http://www.maplesoft.com/ (Symbolic Math Calculator) Grapher (Included with Mac OS X) (Graphing Calculator App) Physics 101 SE http://www.praetersoftware.com (Nice Physics calculation application) MathType http://www.mathtype.com/ (Puts Mathmatical symbols in Word, Pages, Pagemaker, etc) I am also interested in finding a suitable AutoCAD replacement (AutoDesk's AutoCAD can only be run under Virtual PC on current Macs) that runs under OS X. There is a wealth of information available at www.architosh.com. Currently good options look like Vectorworks, Archicad, PowerCAD, TurboCAD and MacDraft with Vectorworks and ArchiCAD leading the pack. I'm not sure why, but Mac based CAD solutions tend to use a point-click interface rather than the traditional command-line interface. Also, I am interested in finding out if Mathmatica and MatLAB are better or what uses they have that differ from Maple but my school uses Maple in there labs so I haven't gotten the chance to test it out yet. I guess I will probably find this out as I progress in my major though.
