Mathematical models: from sundials to number engines
Since the dawn of civilisation, humans have used everyday materials to create mathematical models of the world around them. This album explores the ancient Greeks' astrolabe as a model of the skies; the sundial, to tell the time; Babylonian clay tablets to record wages and trading of sheep; wooden tallies for bulk-buying beer, the Incas' use of knots and string, and the sophisticated number-engine invented by Charles Babbage. This material forms part of The Open University course MST121 Using ma

"Environmental Degradation and Deforestation in Thailand and Cambodia"
Alan Kolata is Neukom Family Distinguished Service Professor of Anthropology, The University of Chicago. There is little doubt that climate change, deforestation, erosion, and the unequal distribution of natural resources around the globe are of pressing importance everywhere, but these problems are perhaps most acute in Asia, home to 64 percent of the world’s population. Much of this population (1 and 1.3 billion, respectively) is concentrated in India and China, two countries with rapidly g

5.4 Emergency planning as a public protection activity

Uniformed emergency services – police, fire authorities and ambulance services – and organisations such as NHS hospitals, have an obvious role in the response to civil emergencies. Local authorities have an important, although less clearly defined, role. This is based on a mixture of specific legal duties coupled to a general ‘duty of care’ to maintain essential services even in an emergency. Much of this section describes the work of local authority emergency planning officers (

1.3.5 Corporate connections

As I mentioned in Section 2, what was happening in the factories of overseas contractors was said to have appeared remote to most, if not all, the chief executive officers of the clothing multinationals in the 1980s. Overseas contractors were selected on the basis of market price, quality and reliability, not on whether forced or child labour happened to be employed to stitch the product together. However, all that changed in the early 1990s when the geographical ties between the big retailer

1 Imagination

Imagination, a licentious and vagrant faculty, unsusceptible of limitations and impatient of restraint, has always endeavoured to baffle the logician, to perplex the confines of distinction, and burst the enclosures of regularity.

(Samuel Johnson, Rambler, no. 125, 28 May 1751)

In much of western thought, the imagination has an ambiguous status, seemingly poised between spirit and nature, m

2.3 What is a ‘business’?

The vast majority of companies are, indeed, set up and run with ‘commercial objects’ – in other words, they are business enterprises, or ‘undertakings’, set up to trade and make a profit. It is principally in the context of the company as a form of business organisation (or ‘business medium’) that we will be studying it. So, before we start to look in detail at what companies are, it is a good idea to have a grasp of what companies do, which will lead us on to consider why they
