The data set in Table 7 (section 1.8) comprised non-numerical or categorical data. Such data often appear in newspaper reports and are usually represented as one or other of two types of graphical display, one type is called a pie chart and the other a bar chart; these are arguably the graphical displays most familiar to the general public, and are certainly ones that you will have seen before. Pie charts are discussed in section 2.2 and bar charts in section 2.4. Some problems

To what extent are you your body? The seventeenth-century philosopher RenÃ© Descartes saw human subjective experience (including rationality, thought and spirituality) as separate and fundamentally different from the objective world of matter, that of our bodies and the physical universe. This idea of a fundamental divide between mind and matter (as two different kinds of â€˜stuffâ€™) set the stage for centuries of debate on what came to be known as Cartesian dualism. Critics of this w

Many people have the impression that underground water occupies vast caverns, such as those in the Derbyshire Peak District, flowing from one cavern to another along underground rivers. This is a common misconception: underground caverns are fairly rare, but huge quantities of water exist underground, within rocks. This is because many rocks contain pores, spaces that come in all shapes and sizes. In sediments, and consequently sedimentary rocks, there are often pores between grains which can

In a world with a bewildering mix of fact and fiction, and in which social and mainstream media only add to the confusion, how do we separate out false or dubious claims from the well-founded and evidence-based? Research and clinical psychologist Prof Scott Lilienfeld joins science host Dr Andi Horvath to help us distinguish pseudoscience from

Scientists are increasingly being asked to discuss and communicate social and ethical issues that arise from their work. Understanding these issues is also part of developing science and technology responsibly. And yet the formal education system in the UK often requires scientists to focus on core science subjects at the expense of learning about the social and ethical implications of their work. How then does a modern scientist begin to engage with these important issues? One solution is to

Although both search engines and subject gateways will help you find the resources that you need, the types of information that you find will differ.

Search engines such as Google and Yahoo! search the internet for keywords or phrases, and then show you the results. These results are not mediated by the search engines, and therefore you need to use your own judgement on the reliability of the results. You may, for example, find websites written by experts, alongside websites written by

Los Aztecas - La Noche Triste (en espaÃ±ol)
Al ver regresar a Cortés los mexicas decidieron dejarlo pasar a la ciudad porque pensaron que iba a ser más fácil derrotarlo con los demás españoles dentro de la ciudad que enfrentarse a él fuera de la ciudad. Entonces Cortés se pudo reunir con los españoles sitiados y después de unos días de batallas infructuosas decidió que la única salida que tenían era huir de la Ciudad de México. 1:49

The lack of safe drinking water in many developing countries has prompted research into simple methods of disinfecting small quantities of water. One such investigation at the University of Beirut in the Lebanon revealed that 99.9% of total bacteria in a water sample could be destroyed by 300 minutes exposure to direct sunlight. In effect this means that if you left a sample of water in a translucent container, a lot of the bacteria in it would be killed.

Research to date has concentrat
