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)
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

Discovering Science Around Us - This video looks at how science is all around us and shows how a special exhibition is teaching this to young students. (01:19)
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 2.2 Tables and percentages Tables often give information in percentages. The table below indicates how the size of households in Great Britain changed over a period of nearly 30 years.
