Physics in architecture
Developed in 1998 by Dr John Whittle (Department of the Built Environment) using Authorware, this package contains brief interactive notes on eight areas of physics in which architects need a working knowledge. However, it is also useful to others in science, engineering and social sciences looking for an introduction to the topics concerned. These topics are: Units of measurement; Scalar and vector quantities; Newton’s laws; Mass and weight; Action and reaction; Waves; Heat, work and energy;

Introduction

The unit will examine the Enlightenment. To help understand the nature and scale of the cultural changes of the time, we offer a 'map' of the conceptual territory and the intellectual and cultural climate. We will examine the impact of Enlightenment on a variety of areas including science, religion, the classics, art and nature. Finally, we will examine the forces of change which led from Enlightenment to Romanticism.

5 Designer babies?

A character under genetic influence where the distinction between treatment and enhancement is hard to draw is height. Treatment of short stature – with human growth hormone made in genetically manipulated bacteria – has already given rise to controversy about how short a child needs to be for treatment to count as meeting a medical need. That is, how tall is tall enough?

As we identify genes that have effects on many other human characters, from appearance to, perhaps, intelligence

Misoriented interphase boundary between h-BN and SiC grains
The micrograph shows misoriented interphase boundary between h-BN (precipitate) and SiC grains (within a silicon nitride particulate-reinforced silicon carbide composite). The occurrence of BN inclusions results from the introduction of colloidal BN into the hot isostatic pressing process. They are formed from B2O3 present as a thin surface film on the BN particles in the barrier layer. B2O3 will be molten during the pressing process and will diffuse rapidly into the powder compact and react wit

4.7 Informing students

Students need accurate information about accessibility before they enrol on a course. This may seem like common sense, but it is a significant contributor to students’ legal complaints. It is important that details of reasonable adjustments are carefully recorded, including the limitations of alternative formats and accessible design. The second accessibility activity, ‘Specifying, designing and evaluating accessibility’, will look more closely at specifying and evaluating web resources

1.1 What happens during an earthquake?

The Earth is an active planet, with activity occurring in the oceans, in the atmosphere and in the solid Earth itself. This course looks at a dramatic example of solid Earth activity: earthquakes.

You probably have some idea from newspapers, television or perhaps personal experience, of just how powerful earthquakes can be. In a matter of minutes earthquakes have devastated cities and killed a quarter of a million people. I was in only a medium-sized earthquake in 1978, but even that ha

2.12 Fluid balance

Although a person can survive for several weeks without food, without fluids, someone can survive for only a few days. A loss of water equivalent to just 1% of body weight is enough to make someone feel thirsty and to have an effect on ability to concentrate. Such a loss has been shown in some studies in schools to result in a 10% decrease in the mental performance of children. A 4% loss results in dizziness and reduced muscle power. By the time there is a 6% loss, the heart is racing and swe

2.1 Planning your search

Your approach to searching will depend to a great extent on what kind of person you are. In an ideal world, when searching for information for a specific purpose, we would all find what exactly we were looking for at the first attempt, especially if we are in a hurry. However, it's always a good idea to have some kind of plan when you are searching for information, if only to help you plan your time and make sure you find the information you need.
