A quick start with Mathematica Steven Tschantz 1/8/09 Notebooks and cells Mathematica files are called notebooks. Notebooks record the calculations you do, like an experimental scientist's lab notebook. The result can be edited, organized, and reevaluated as a kind of proof of a calculation. Notebooks can also be annotated with additional text and formatted as reports. The Mathematica frontend is the WYSIWYG editor that you use to prepare notebooks. It communicates with the Mathemat- ica kernel, the program that does computation. A notebook is a vertical sequence of cells and groups of cells, as delimited by brackets at right. Cells are of various types with distinct formatting and functions. Headings, sections, and text cells allow you to produce a polished report. Input you want evaluated is typed in an input cell. You evaluate the input by pressing shift-return, sending the command to the kernel, with any resulting output placed in a following output cell. The editing insertion point is indicated by a small vertical bar when typing within a cell, or by a horizontal bar across the window when inserting into the vertical sequence of cells. You may also select the cell brackets to operate on cells or groups of cells, for example to cut or copy whole cells. Double clicking on a grouping bracket opens or closes a group of cells, allowing a condensed outline view of a document. If you are at the bottom of the notebook or between cells and start typing, you will start a new input cell. Evaluating the input by pressing shift-return produces an output cell and leaves you after the output ready to start a new input cell. This is the simplest way to start using Mathematica .
