3.2 The principles of scanning probe microscopes

Scanning probe microscopy is a term that is applied to a set of imaging methods based on a common element: a fine stylus. In many ways, what scanning probe microscopes do is similar to what a gramophone does. A gramophone stylus scans a spiral groove (by travelling along it) on which information has been encoded in the form of undulations in the groove wall. Side-to-side and up-and-down movements of the stylus (which is mounted on one end of a rod supported and pivoted at its centre) as it fo

4.5 Choosing to distinguish between complex situations and complex systems

Within some of the lineages of systems thinking and practice (Figure 24), the idea that system complexity is a property of what is observed about some ‘real world’ system, is known as classical or type 1 complexity. Exploring type 1 complexity, Russell Ackoff (1981, pp. 26–33) c

2 The word ‘freedom’

The word ‘freedom’ can have powerful emotive force, that is, the power to arouse strong emotions. Its connotations are almost exclusively positive. If you describe a group as ‘freedom fighters’ this suggests that you approve of the cause for which they are fighting; call them ‘terrorists’ and you make clear your disapproval.

7.2 Developing a strategy

Present notes/records that show you have planned your use of IT skills. Your evidence must include:

  • the goals you hope to achieve over 3–4 months or so; you should indicate how these goals relate to the context in which you are working and to your current capabilities;

  • notes about the resources you might use, and what information you need to research to achieve your goals; for example, discussions and e-conferences, online resources, s

The Heart of the Matter
This lesson describes how the circulatory system works, including the heart, blood vessels and blood. Students learn about the chambers and valves of the heart, the difference between veins and arteries, and the different components of blood. This lesson also covers the technology engineers have developed to repair the heart if it is damaged. Students also understand how the circulatory system is affected during spaceflight (e.g., astronauts lose muscle in their heart during space travel).
