Gastrophysics – The New Science of Eating [Audio]
Speaker(s): Professor Charles Spence | Why do we consume 35% more food when eating with one more person, and 75% more when with three? Why are 27% of drinks bought on aeroplanes tomato juice? How are chefs and companies planning to transform our dining experiences, and what can we learn from their cutting-edge insights to make memorable meals at home? These are just some of the ingredients of Gastrophysics, in which the pioneering Oxford professor Charles Spence shows how our senses link up in t

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.

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

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

4.2.1 Search engines: what are they?

The computer application that facilitates finding things on the web is known as a search engine. This is an application that serves a similar function to an index in a book. Figure 9(a) shows the home page of a typical search engine called Google.

6.4 Summary

Amplitude refers to the size of a sine wave. It can be defined in various ways, but a standard definition is that it is the maximum value of a wave's departure from its average value. (The average value of a sine wave lies midway between its peaks and troughs.) The size of a sine wave is sometimes also expressed as a peak-to-peak amplitude, which is the vertical distance from peak to trough.

Root-mean-square (r.m.s.) amplitude is a way of specifying the size of a sine wave so that compa

5.5 Emergency planning as an organisational management function

If emergency services' EPOs plan to respond to other people's emergencies, people managing a business activity with major incident potential have a different perspective. They have to respond to emergencies within their own organisation. In effect, if an incident occurs, the organisation is itself in a crisis, with functionality impaired. All of this comes into the corporate governance area and the implications of internal control. This requires companies to ensure that they have a sound syst

2.2 Postscript

A headline-grabbing weekend of ‘midsummer madness’, when six murders occurred in (parts of) Glasgow over the weekend of 5–6 August 1995, reinforced the ongoing nature of contestation and debate about the issues discussed in the programme. As noted in The Scotsman (8 August 1995), the legacy of the imagery of No Mean City was quickly resurrected by the press – for example, ‘a darker side to that much-vaunted transformation of Glasgow from No Mean City to Culture City’
