Mathematica is a huge language. It will take some time before you are familiar with most of what it contains. The only advice I could offer is to purchase a hard copy of the mathematica book and Guide to Standard Add-On Packages and put them on your bed stand and use them to fall asleep at night while you browse the pages. This is hard to do with the on-line version. -- Remove the _nospam_ in the return address to respond.
