Abstract algebra, which is where you'll find coverage of groups, rings, and fields, is usually pretty far removed from applied math. However, the Artin text is probably the *closest* in approach to an applied text that you'll find.

It provides plenty of concrete examples of the abstract stuff and why it is useful. It is not comprehensive, but the topics it chooses are well developed, and you'll never have to ask, "Why does this theorem matter?" It will get you started on groups, rings, and fields.

[sage-support] Error when launching Sage
I've just downloaded and launched Sage on an Ubuntu 8.10 box. I unzipped the file and ran ./sage and got this: WARNING! This Sage install was built on a machine that supports instructions that are not available on this computer. Sage will likely fail with ILLEGAL INSTRUCTION errors! The following processor flags were on the build machine but are not on this computer: nx up I downloaded this image of Sage: sage-3.2-ubuntu32bit-intel-i686-Linux.tar.gz Is there anything I can do?
