6.1 Introduction

The previous sections in this course include many terms which may have been unfamiliar to you: for example, atom, element, compound, molecule and bond. Chemistry has a language all of its own and grasping the terminology can be as much of a problem as understanding the chemistry itself. In Section 6, you will consider the language of chemistry before returning to the examination of bonding.

The Beginning of Earth History
Earth formed over 4.5 billion years ago with its initial condition greatly affected by the trauma of giant impacts. In this lecture, Professor David Stevenson discusses how this trauma affects the similarities and differences between Earth and Moon, the core, possible initial layering of the mantle and the conditions for the early evolution, including timing for the origin of life. This lecture was presented by The Research School of Earth Sciences, ANU College of Science.

5.5.1 Monitors

Nearly all computers are supplied complete with a monitor which opens a window onto the machine's digital world. Without one we could have little idea about what the computer was doing, or even whether it was working at all.

There are two main types of monitor: the CRT (cathode ray tube) and LCD (liquid crystal display). A CRT monitor looks like a television screen, and works in a similar way to a TV or a scanner. A beam of electrons is fired from a gun at the back of the

1.1 Introduction

In this reading I focus on a piece of data to introduce some of the main themes and issues in discourse research. The material I have chosen to examine has historical interest. It is a public text of some import for British society and yet it also has a curiously private and confessional aspect. I am going to look at extracts from Princess Diana's interview with Martin Bashir which was screened in 1995 on Panorama – a British news-documentary television programme.
