10.2 Scientific or technical curiosity

Some inventors understand a scientific phenomenon and set about inventing a technological device to exploit the phenomenon.

The invention of the laser grew from the interest of two researchers in studying the structure and characteristics of a variety of molecules. During the Second World War, Charles H. Townes worked on developing radar navigation bombing systems. After the war he had the idea of modifying the radar techniques and using microwaves to study molecular structure. Subseque

1.3 Overview of ‘normality’

Before we can specify what might be ‘abnormal’, we must first have a clear idea of what we mean by ‘normality’. However, within psychology this is much more difficult than it first appears. As our discussion has shown, psychological ‘normality’ can be defined in terms of:

  • what is ‘average’ or ‘typical’ with respect to statistical frequency;

  • ‘lack of disability’ – where ‘normality’ is defined by reference to

7.1 History

So far, I have provided a brief historical background for England, Scotland, Wales and Northern Ireland, one that accounts for their distinctive identities and for the origins of their differing role within the UK. I have also defined devolution as an asymmetric decentralisation process which responds to the claims advanced by the nations constituting the UK state. What, then, do we mean by Britain? Is it a nation? If so, when did the British nation begin to exist? The historian Linda Colley

French Lesson - Dans la Ville (In the City), Part 6
Learn French by learning vocabulary words for buildings in the city. As the native French speaker recites the words, the words and the appropriate images appear. There is no English spoken. Each French phrase is spoken once. For beginning to intermediate learners. This video features a picture within the picture, so the viewer may want to open the video to 'full screen' to see the smaller image.

2.8 Search engines

The web contains a huge amount of material. Finding specific information is a huge problem; even in the early days of the internet this was a problem which threatened to slow the growth of the net. Fortunately a partial solution to this problem emerged: the search engine. This is a program which accesses a huge database of information about the World Wide Web; it contains individual words in web documents and the location of the documents containing the words. When the user of a search

5.2.2 Continuous variables

Not all numbers are discrete. Consider the following measurements:

  • times to run a marathon

  • temperatures recorded at intervals during a day

  • weight of each bunch of grapes sold at a supermarket yesterday.

Time, temperature and weight are all examples of numerical data, but there is not a restricted set of values that they can take. Whereas you can have 2 or 3 children in a family but not 2.5, with tempe

4.6 What matters?

When the laptop is confirmed to be uncompromised, it is interesting that none of the characters cheers, although they all seem to be relieved. In other words, when the statement comes up, ‘laptop is uncompromised’, people seem to think that is ‘good’, the outcome is fine. They seem to have forgotten that the technician is probably dead at the time. So, in their deliberations, a person's life is forgotten. I am sure that, if they were reminded of it, they would, of course, say that thi

5 Effective use of problem solving skills

The purpose of this assessment unit is for you to create a portfolio of your work to represent your skills in problem solving within your study or work activities. This will involve using criteria to help you select examples of your work that clearly show you can use and improve your skills in problem solving. However, by far the most important aim is that you can use this assessment process to support your learning and improve your performance overall.

Using problem-solving skills is n

4.2 Project life cycles

Earlier I said that a project is: ‘a unique venture with a beginning and an end’ (Boddy and Buchanan, 1992, p. 8). But it must have a middle, too. We say that a project has a ‘life cycle’. This is based on an analogy with living things which are born, live for a period of time, doing things like consuming food and water, breathing, moving, etc., and then finally end (die). There is much discussion about whether there is only one ‘true’ model of a project life cycle or many, and wh

7.3.2 Subtraction

As I indicated at the start of this section, subtraction is converted to addition by replacing the number to be subtracted by its additive inverse, which in the case of binary arithmetic is its 2's complement. An example should make this clear.

3.3 Mixing different forms of data: disjoint union of sets

At the supermarket checkout, some items need to be weighed (organic courgettes for example) and some do not. Let BarcodedItems be the set of items that do not need to be weighed, and WeighedItems be the set of items that must be weighed. When a weighed item is recorded at the till, we must record both the item type and the weight of the item that has been purchased. Earlier, we saw that such a purchase can be seen as an ordered pair, such as (“WALNUTS”, 335), that comes from
