'Energy is Eternal Delight'

William Blake, 1757–1827 (1994)

What do we mean by 'energy'? What does the concept of 'sustainability' entail? And what, for that matter, do we mean by the 'future' in this context?

4.2.1 Defining the problem

It is vital that the problem is identified correctly. If the risk management system is working properly, the problem should not have hit you completely out of the blue, and you should already have some idea what it is about. But, although there is often a temptation to skip the definition phase and go straight to causes and solutions, it is important to be as clear as possible about the nature of the problem as seen from different perspectives, by answering questions such as those below.

Reading what some well-known writers on organisational and national culture have to say will help you recognise some of the main dimensions of culture and reinforces that all of us, including organisations, construct different views of the world as a result of cultural influences. Thus culture plays a key role in the ways in which organisations perceive the en

2.3 Pressure waves and cycles

In this section we shall be looking at the behaviour and properties of pressure waves in the atmosphere.

Sound originates from the motion or vibration of an object. Let's look at an example of a sound wave generated by a vibrating tuning fork. The prongs of the tuning fork move backwards and forwards cyclically. A cycle is a complete series of movements up to the point where the movement starts to repeat itself. As the prongs of the fork vibrate back and forth they push on neighbouring
