5.13 The final Act

In Act 3, Dan and Ned are back in Ned's flat and Ned is showing extreme signs of neurosis and paranoia. Dan can no longer bear Ned's rather dark and erratic behaviour, and he grabs the conversation by suddenly pouring out all the overwhelmingly negative aspects of his life as a dentist, father and lover. Some people might say that ethics is about how to live a ‘good’ life and, clearly, Dan needs a change. He recognises he is not leading a ‘good’ life. He knows all the things that are

6.5 The social construction of quantifiable risk

Earlier in this unit we referred to the way in which social groups can develop shared cognitive schema. One important role for shared cognitive schema is to define the risks that we pay attention to, the dread in which we hold them and the perceived likelihood of their occurrence. Because these perceptions affect behaviour, they also play a role in selecting the risks that we face. In the last half century, some sociologists suggest (e.g. Beck, 1992; Giddens, 1990) that our concerns with risk

2.1 Understanding the polymer state

It was the pioneering scientific work of Hermann Staudinger in the early part of the twentieth century which led to an understanding of the polymer state at an atomic and molecular level. Until then, plastics and rubbers had been developed from naturally occurring substances or discovered during routine synthesis. His research laid the basis for all subsequent discoveries and their commercial development. In essence, he realised that polymers were large molecules built up by the repetition of

Multiplying Rationals
Multiplying rational expressions is basically two simplifying problems put together. This video clip explains how to multiply rationals by factoring both numerators and denominators and identifying equivalents of one to cancel. Dividing rational expressions is the same as multiplying with one additional step—we take the reciprocal of the second fraction and change the division to multiplication. (1:41)

6.1 Introduction

We have now looked at how formal rules are formulated, and at some of the strategies that may be deployed when interpreting them. In this part we will take this one step further and explore in more detail something that we have already touched on and thought about – the application of rules. This is a really important thing to understand, since rules are designed to regulate conduct, and have to be applied to instances of the conduct with which they are concerned.

Central Angles
This video explains how a central angle is an angle where the vertex is on the center of the circle and the endpoints are on the circle. The endpoints on the circle are also the endpoints for the angle's intercepted arc. The angle measure of the central angle is congruent to the measure of the intercepted arc which is an important fact when finding missing arcs or central angles. (2:12)

Inscribed Angles
This video describes how inscribed angles are angles whose vertices are on a circle and that intersect an arc on the circle. The measure of an inscribed angle is half of the measure of the intercepted arc and half the measure of the central angle intersecting the same arc. Inscribed angles that intercept the same arc are congruent. (1:44)

Angles in Semicircles
If an angle is inscribed in a semicircle, it will be half the measure of a semicircle (180 degrees), therefore measuring 90 degrees. This video describes how angles in a semicircle can be used to find missing missing angles and lengths. Pythagorean's theorem can be used to find missing lengths (remember that the diameter is the hypotenuse). Also, the measure of an angle formed by a chord to a tangent is half the intercepted arc.
