Introduction This unit is aimed at geography teachers, or those with an interest in studying or teaching geography. This unit looks at the contribution that geography can make in the education of young people and the characteristics and purpose of geography as a subject.
1.4 Molecular substances Chlorine, bromine and iodine belong to a family of elements called the halogens. At room temperature, chlorine (Figure 2e) is a gas, bromine (Figure 2d) is a liquid and iodin
1 What to expect In this unit you will look at how sport can be understood from a scientific perspective. This is a large topic with many possible approaches. We will try to focus on specific details while maintaining a broad overview of the subject using examples from many different sports such as running, athletics, cycling and swimming to illustrate the different ways in which sport and science interact. You will see that even a brief introduction to the science of the human body is enough to answer
Modelling for Virtual Reality in Architecture
CAAD systems are using object modelling methods for building databases to make information available. Object data must then be made useful for many different purposes in the design process. Even if the capacity of the computer will allow an almost unlimited amount of information to be transformed, the eye does not make the transformations in the same ?simple? mathematical way. Trained architects have to involve in an inventive process of finding ways to ?harmonize? this new medium with the human
Balloon crash CVS01_01_031 Tales of balloon flight. A hand-coloured engraving showing a maritime rescue that took place on 1st September 1874. French balloonists Jules and Caroline Durouf were rescued by English fishermen Oxley and Buscone, after their balloon 'Le Tricolore' ditched in the North Sea. From the Cecil Victor Shadbolt collection of lantern slides dating from 1882-1892.

Religion in history: conflict, conversion and coexistence
The coexistence of multiple religious communities has been a source of both opposition and diversity since the very foundation of human civilization. This album explores the interaction of competing communities in compelling depth, highlighting periods and cities that experienced turbulence, and occasionally harmony, from such an intermingling of beliefs and ideas. A huge historical range, from the very beginnings of early Christianity to modern-day Africa, is rigorously examined in cultural, so
A Capitalism for the People [Audio]
Speaker(s): Professor Luigi Zingales | When the Italian-born economist Luigi Zingales first arrived in the United States in the 1980s, he embraced the American dream: the belief that what brings you success is hard work, not luck or who you know. But the economic events of the past decade, combined with the actions of politicians from both sides, have undermined capitalism's reputation. In A Capitalism for the People, which he will discuss in this lecture, Zingales warns that the US economy risk

References 2 Pressure for change Bedford Mencap was founded in 1955, as a branch of the National Association for Parents of Backward Children. It provides services for its members, such as the Welfare Visitors Scheme, and also campaigns for change at national and local levels. When the branch was founded there was no provision for families other than the advice to put their child into a mental handicap hospital. Now, partly due to the efforts of Mencap, there is far more on offer. However, you'll shortly be hearing that whil Introduction This course will give you a stimulating and insightful account of the ways in which economists have tried to understand what labour market discrimination is and what its sources are. Notice the reference to the ‘ways [plural] … economists have tried to understand’. The most basic message of this course is that economics is not a subject in which there is one single correct answer. This course will also assist you in developing your ability to use and evaluate economic theory, and 12.620J Classical Mechanics: A Computational Approach (MIT) Discovering Science Around Us 3.3.1 Try some yourself A friend has been quoted a price of £25.50 per square yard for tarmac surfacing of his yard. The yard measures 6 yards by 10 feet. Here is his calculation of the total cost. What is wrong with it? cost = 4.1.1 Getting off to a good start You may find it useful to plan the way you will start your exam. Having a routine can be calming when under pressure. This is from a student who recommends a checklist:
I have a mental checklist of what I need to do once I've turned over the paper. I do this because I used to rush in and answer the fir 1.1: Converting to component form In some applications of vectors there is a need to move
backwards and forwards between geometric form and component form; we
deal here with how to achieve this. To start with, we recall definitions of cosine and sine. If
P is a point on the unit circle, and the line segment
OP makes an angle θ measured anticlockwise
from the positive x-axis, then
cos θ is the x-coordinate of
P and sin θ is the
y-coordinate of P ( Westward Expansion Overview 1.2.7 Summary What we must do to understand numbers as they are used as evidence in social science is to practise and so become familiar with them, and to understand the conventions which determine how they are used. Sets of numerical data can be presented in many ways, as tables, bar charts, pie charts or line graphs. These are just different ways of trying to represent or make a picture of numbers. Which is used is largely a matter of which best shows
We will study the fundamental principles of classical mechanics, with a modern emphasis on the qualitative structure of phase space. We will use computational ideas to formulate the principles of mechanics precisely. Expression in a computational framework encourages clear thinking and active exploration.
We will consider the following topics: the Lagrangian formulation; action, variational principles, and equations of motion; Hamilton's principle; conserved quantities; rigid bodies and tops; Ha
