Computer screens

The four channel scanning system showed stable measurements up to 250 m/min drawing speed. At 300-350 m/min some measurements were unstable on two channels. At drawing velocities over 350 m/min measurements were unstable on all four channels. The four traces are better identified in colors on the computer screen than in this grey tone figure. 

Analogously to STM, the image obtained in a force microscopy experiment is conventionally displayed on the computer screen as grey scales or false colour, with the lightest shades corresponding to peaks (or highest forces) and darkest shades corresponding to valleys (or lowest forces). 

A data system stores the mass spectrum until required, when it can be printed at leisure or viewed immediately on the computer screen.

Using computers to display molecular structure is an attractive alternative to traditional line drawings for several reasons. First, the model displayed on a computer screen looks and behaves more like a real molecule than a drawing does. The computer model can be viewed from different angles, and different display formats can be used to show atomic positions, atomic volumes, and other features of interest. Second, the computer can produce a good model even when the student does not know how to make an accurate drawing. Thus, the student, working with a computer, can explore new areas of chemistry ... 

Plate 7. A snapshot of Brian Silverman s Brain CA [sil87]. Brain has three states 0, 1, and 2. If a site is in state 1, it enters state 2. If a site is in state 2, it enters state 0. If a site is in state 0, it counts how many of its eight neeirest neighbors ru e on. If exactly two of them are on, the site turns on. When viewed in real-time on a computer screen, Brain displays a very rich behavioral repertoire. 

The output of a CA simulation carried out on a computer comes in two different forms a visual output that is displayed on the computer screen, and numerical data summaries compiled in output files that are generated during each run. The visual output allows the observer to follow the system as it evolves, and can be very helpful in comprehending the overall process of the system s evolution. The data summaries in the output files are more suitable for quantitative analysis of the details of this evolution.
