2.1 Introduction
Stars can necessarily be observed only at a distance. This unit introduces the Hertzsprung–Russell diagram, an essential tool in understanding the nature of stars. You should have some understanding of the basic stellar properties of luminosity and temperature in order to get the most from the unit.
Introduction
This unit is concerned with the technique of expressing a periodic function as a sum of terms, where each term is a constant, a sine function or a cosine function. There is a strong analogy with the technique of expressing a (non-periodic) function as a Taylor series, which is a sum of terms that are powers of the independent variable(s); in both cases, working with just the first few terms generally gives a useful approximation. This unit assumes the following background knowledge: the definit
Introduction The topic of ‘governance’ is one that has gained popularity, and the term is now used to embrace a range of concepts. This unit establishes some basic principles that will form the basis of your study. You will have the opportunity to consider how well these principles match up with your own observations of corporate organisations and behaviour This material is from our archive and is an adapted extract from Issues in international financial reporting (B853) which is no
Introduction
This unit introduces you to analysing academic writing and, in particular, the way an article might be structured to clearly explain an investigation to other researchers. It explores observation of children and young people using qualitative observation approaches in small-scale studies.
Introduction We begin this unit by looking at an estuary, a place where sea, land and sky meet. We have chosen a particular estuary: the Blackwater estuary on the Essex coast in eastern England. Although the Blackwater has its own unique characteristics, it is used here as a setting, a device for approaching the study of environments. Like any other estuary, the Blackwater brings together a diverse range of processes, elements and issues that constitute the environment. It offers us a way into thinking ab
Introduction to improving own learning and performance
This unit focuses on higher level skills. Skills development is complementary to other learning – it cannot be done in isolation. The higher level skills in this material aim to raise your awareness of the processes of learning and development – other subject-based material must supply the context and motivation for this. Key skills underpin the ability to carry out successfully, and improve on, a wide range of tasks in higher education, employment and wherever there is a continuation of le

Introduction
This unit is intended to further develop your understanding of Newtonian mechanics in relation to oscillating systems. In addition to a basic grounding in solving systems of differential equations, this unit assumes that you have some understanding of eigenvalues and eigenvectors.
Introduction
The new discipline of astrobiology – that is, the science of searching for extraterrestrial life – is not only rapdly growing, but has also captured the public imagination. This unit examines the emergence of icy satellites of distant planets as potential sites of extraterrestrial life. Focussing on the case study of Jupiter's moon Europa, the unit looks at the potential for life there, and speculates on the ethics of searching for life elsewhere in the solar system.

Introduction This unit introduces common techniques underlying free verse and traditional forms of poetry, and how it is necessary to use these techniques in order to harness what T.S. Eliot called the ‘logic of the imagination’ (Eliot, 1975, p. 77). We discuss the possibility of using your own experience, but also the power of imagination, and of utilising different personae in your poems. You are also introduced to the basic terminology and practical elements of poetry – the line, line-breaks
1 What is poetry?: an introduction
Have you always wanted to try to write poetry but never quite managed to start? This unit is designed to illustrate the techniques behind both the traditional forms of poetry and free verse. You will learn how you can use your own experiences to develop ideas and how to harness your imagination.
Introduction This unit looks at how characters might be drawn and how setting is established. It works on the different levels of c
Introduction
This unit shows how various situations can be modelled by a system of linear differential equations. The prerequisite requirements to gain full advantage from this unit are a basic understanding of differential equations, a familiarity with the properties of matrices and determinants and some understanding of eigenvalues and eigenvectors.
Introduction
This unit lays the foundation of Newtonian mechanics and in particular the procedure for solving dynamics problems. The preresquisite skills needed for this unit are the ability to solve first and second-order differential equations, a knowledge of vectors, and an understanding of the concept of a force
Introduction ‘Freedom’ can mean many different things. Here we're concerned with political freedom. Isaiah Berlin distinguished between a concept of negative freedom and a concept of positive freedom. You will examine these concepts and learn to recognise the difference between freedom from constraint and the freedom that comes from self-mastery or self-realisation. The following material is taken from the book Arguments for Freedom ‘1999’ authored by Nigel Warburton of The
Introduction This unit gives you an idea of what it is like to study philosophy, introducing you to the teaching methods employed by the Open University in teaching philosophy. If you are considering studying philosophy, we recommend you start here. Although the unit is mainly for people who are new to philosophy, you may find it helpful even if you already have some experience of the subject. The following material has been written by Maria Kasmirli with quotations from Dr Nigel Warburton. Th
