Learning outcomes

By the end of this unit you should be able to look at how:

  • experiences of being an older person are shaped through a historical and mutually constitutive process involving an interplay between the personal, work and welfare; and the points of continuity and difference this interplay illuminates;

  • personal experiences of being older are constituted not only through age divisions, but also through loci of social difference and inequality organised around class, (dis)

9.2 Dynamic range

The quietest sound we can hear corresponds to a pressure wave with an amplitude of about 10 μPa, which is a very small pressure amplitude indeed. It is about 0.000 000 01 per cent of nominal atmospheric pressure, and the resultant displacement of the eardrum is less than a tenth of the diameter of a hydrogen molecule.

At the upper end of the scale, a sound that is distressingly loud might typically correspond to a pressure wave with an amplitude of 0.01 per cent of nominal atmospheric

2.4.1 Electromagnetism and fields

When Newton wrote about 'The System of the World' in Part 3 of Principia, the only forces he could discuss in any detail were the contact forces that arose when one object touched another, and gravity, which acted at a distance. Even so, Newton thought that there were other forces at work in the world, and hoped they might eventually be brought within his overall scheme just as gravity had been. In fact, Newton wrote:

An Interface Proposal for Collaborative Architectural Design Process
The aim of this paper is to explore how new technological opportunities affect approaches of designers during collaborative architectural design process. Which factors affect the communication and the quality of interaction? The study is based on two phases: the data input by the designer via devices to the computer environment and the transformation of data into design product in the software by scripting addition. Input devices that are used are 3D mouse, graphic tablet as a tangible interface

Total number of neurons—not enlarged prefrontal region—hallmark of human brain

1.5.5 Point spread function and angular resolution

The image of a point-like source of light (such as a distant star) obtained using a telescope will never be a purely point-like image. Even in the absence of aberrations and atmospheric turbulence to distort the image, the image of a point-like object will be extended due to diffraction of light by the telescope aperture. The bigger the aperture, the smaller is the effect, but it is still present nonetheless. The intensity of the image of a point-like object will take the form shown in

The Physics of the Violin
Jesse Liu, winner of the the departmental Speaking Competition for undergraduates, gives a short talk on the physics of a violin. The violin and elastic band are both string instruments. Yet what is it about the first that allows it to produce sounds many would regard as beautiful? I'll explore the physics behind music and the violin to illuminate this intersection of art and science.

Conclusion

Section 1 Superconductivity was discovered in 1911, and in the century since then there have been many developments in knowledge of the properties of superconductors and the materials that become superconducting, in the theoretical understanding of superconductivity, and in the applications of superconductors.

Section 2 A superconductor has zero resistance to flow of electric current, and can sustain a current indefinitely. The magnetic flux remains constant in a completel

Introduction

The course uses the example of climate change to highlight the dynamic and volatile character of the planet, and how globalisation links together, in often unequal ways, people and places across the world. The course focuses on the potentially momentous impact of global environmental change on Pacific Islands like Tuvalu. It introduces students to geographical ways of thinking about the world.

Introduction

Your course might not include any maths or technical content but, at some point during your course, it’s likely that you’ll come across information represented in charts, graphs and tables. You’ll be expected to know how to interpret this information, and possibly encouraged to present your own findings in this way. This course will help you to develop the skills you need to do this, and gain the confidence to use them.

This course can be used in conjunction with, and builds on th

Introduction

The issue of ‘citizenship, work and the economy’ is often neglected in everyday discussions of citizenship. But a moment's reflection should demonstrate how important it is. The vast majority of us will spend the bulk of our adult lives working in some context or another, and our engagement with economic activity more generally is obvious (and not just as consumers).

Many young people are also intimately tied up with work. School children often have part-time evening, weekend or ho
