2.1.1 The morality play

Before looking at the play's opening scene I should add a brief note on the medieval morality play, the type of drama on which Marlowe draws in adapting The Damnable Life for the stage. After the Prologue and Faustus's long opening speech, you may have been startled by the appearance of the Good and Evil Angels. Even if you had expected to find supernatural beings in a play about a man who sells his soul to the devil, the Good and Evil Angels may have struck you as strange, perh

3.1 (4A) Exploring dynamic relationships using sign graphs

Here is where things start getting really interesting in terms of system dynamics! So far, most of your modelling work has been pretty static, with a limited sense of how things change over time. In fact, the behaviour of complex systems is rarely stable. Sometimes change is exponential (e.g. the growth of the World Wide Web); sometimes systems crash and burn (e.g. extinction of populations); but often systems demonstrate repetitive patterns of behaviour (e.g. economic boom and bust cycles).

2.3 Multiplying powers

Powers of ten can be used to investigate what happens when two powers of the same number are multiplied together. For example, consider multiplying 10 by 100:

A billion is a thousand million. In terms of powers this is:

3.5 Muscle

There are different sorts of muscle in the body and they have different functions. Skeletal muscles are the muscles that, for example, are used for movement in your arms and legs.

Skeletal muscles store glucose as glycogen (Figure 4) and are able to use glucose as a fuel. Insulin stimulates muscles to take up glucose, and w

7.3 Frequency tables

So far you have looked at small sets of data, which are relatively easy to analyse. Naturally, this is not always the case and you need to consider how to work with a larger set of data. Data set B shows 30 TMA scores recorded by a tutor in the order that the scripts were marked.

2.3.5 Mixed structures

Teams often have mixed structures:

  • some members may be employed to work full time on the project and be fully responsible to the project manager. Project managers themselves are usually employed full time.

  • others may work part time, and be responsible to the project manager only during their time on the project. For example, internal staff may well work on several projects at the same time. Alternatively, an external consultant workin

7.3 Studying protein–protein interactions

The investigation of protein–protein interactions is a very important aspect of understanding proteins. Identifying binding partners can give insight into a protein's function. Many different methods and technologies have been developed to identify and characterise interactions between proteins, a few of which are described here.

1.5.3 Summary of Section 1.5

  1. Some annual plants and insects can spend the winter at juvenile stages, such as seed, egg, larva or pupa. Butterflies in Britain display a variety of juvenile overwintering strategies.

  2. Migration often results in high mortality, but completion of the journey results in higher breeding success, due to increased availability of food and fewer competitors.

  3. Birds increase their body mass, sometimes by up to 50%, prior to migration. T

5.5.3 Plotters

A plotter is a special type of printing device mostly used by architects, engineers and map makers. Here the printed output is produced by moving a pen across the paper. Sometimes several differently coloured pens are available. Plotters are obviously most suitable for line drawings, which is why architects, for instance, use them. I've mentioned them here, however, because – in contrast with monitors and printers – they produce an analogue output directly.
