5.6.3 Conformation and crystallinity

If there are key connections between the chain configuration and crystallisation, you might also expect some more subtle effects from rotation about chain bonds. After all, polymer chains must be able to twist into the regular conformation demanded for crystal structures (Figure 57(a)). And what influence will rotation have on

1.4.2 Concepts of a good death

The concept of a ‘good death’ is highly contentious. Definitions vary according to different historical and cultural contexts. At certain points in history there has existed formal teaching about the proper conduct of death and dying, perhaps the most noteworthy being the medieval books on ‘the art of dying well’. These were often illustrated with woodcuts showing angels and devils at the deathbed competing for the dying person’s soul. The accompanying inscriptions explain that God

1.4.1 Discourse involves work

If discourse is doing something rather than doing nothing, what kinds of things are being done? We can see that Diana's account in Extract 1, like all accounts, constructs a version of social reality. When we talk we have open to us multiple possibilities for characterizing ourselves and events. Indeed, there are many ways Diana could have answered Bashir's first question in the extract above. Any one description competes with a range of alternatives and indeed some of these alternativ

3.1 Jupiter's rings and satellites

There can be few people who have never heard of the rings of Saturn, but you may be surprised to discover that every one of the giant planets has rings, including Jupiter. Another feature common to the giant planets is that each has a numerous family of satellites. The likeness goes deeper than that, because there are strong similarities in the organization of each of these families.

There are small inner satellites ('moonlets') in near-circular prograde orbits that lie virtually in the

Psychology of Early Design in Architecture
Lately there has been a good deal of emphasis on the early stages of the design process, particularly by developers of computer aids and quantitative design models for both evaluation and generation of designs in a variety of domains. Yet, there is little understanding of the early design-process. While the early design process as manifested by human designers need not be the sole basis of the description of this phase, it certainly represents and important kernel of knowledge, especially for th

1.5.2 Sedimentary processes

Sedimentary grains are formed when the rocks at the Earth's surface are slowly broken up physically by exposure to wind and frost, and decomposed (chemically) by rainwater or biological action. These processes are collectively termed weathering. Once a rock has been broken up by weathering, the small rock fragments and individual mineral grains can be eroded from their place of origin by water, wind or glaciers and transported to be deposited elsewhere as roughly horizontal layers of sediment

2 Doing philosophy

This section will illustrate the points just made and give you a sense of what it will be like to do philosophy. We shall look at some extracts from the first A211 course book, Arguments for Freedom by Nigel Warburton, and see how philosophical skills can help us to think about political freedom. There will also be a few short exercises for you to do. Although we shall look at actual extracts from the course material, you should bear in mind that this topic will be covered in mu

When Will America and China go to war? [Audio]
Speaker(s): Professor Michael Cox | We have been told for years that war between great powers is a thing of the past: something that has been consigned into that proverbial dustbin of history. Yet today serious writers and influential strategic thinkers in the USA and China are now suggesting that war in East Asia is a very real possibility as China rises - and becomes more assertive - and the United States supported by its Asian allies seeks to limit China’s reach. But how real is the danger

3.7 A note on straight-line graphs and their gradients

We end this section by reviewing some of the important features of straight-line graphs, though we do so in terms of two general variables z and y, rather than x and t, in order to emphasise their generality. If the graph of z against y is a straight line of the kind shown in Figure 22, then z and y are related by an equation of the form

1.2 Satellite systems and their origins

The satellite systems of the giant planets have several features in common. Most satellites are in synchronous rotation, always keeping the same face towards their planet. Irregularly shaped moonlets associated with the ring system orbit closest to the planet. They travel in near-circular prograde orbits in the planet's equatorial plane. ('Prograde' in this sense means orbiting in the same direction as the planet's spin.) These moonlets (like the rings) are believed to be fragments of larger

5 Conclusion

This chapter has enabled you to think about the essential role of technological change in determining economy-wide growth and the growth of firms and industries. We have seen that many issues surrounding the new economy are really issues around the dynamics of technological change: rapid increases in productivity, the emergence of many small firms, new products and new processes, and so on. The main lesson of the unit has been to provide a historical perspective to the introduction of new tec
