7.5 Outstanding issues
The field of active galaxies is recognised as one of increasing importance. But how do we know there are different kinds of galaxy? What are active galaxies? How are they powered? This unit examines the different types of active galaxy and looks at the crucial role of the active galactic nucleus and the energy source at its heart.

3 Appendix: Some highlights of physics
The restless Universe introduces you to major achievements and figures in the history of physics, from Copernicus to Einstein and beyond. The route from classical to quantum physics will be laid out for you without recourse to challenging mathematics but with the fundamental features of theories and discoveries described in sufficient detail to whet your appetite for further physics study.

1.1 What happens during an earthquake?
Earthquakes shake the ground surface, can cause buildings to collapse, disrupt transport and services, and can cause fires. They can trigger landslides and tsunami – in short, earthquakes can be very destructive. In this unit you will look at why, where and what happens when they occur and also at how earthquakes are assessed qualitatively and quantitatively.
Checklist of common features
This unit will help you to identify and use information in Science and Nature, whether for your work, study or personal purposes. Experiment with some of the key resources in this subject area, and learn about the skills which will enable you to plan searches for information, so you can find what you are looking for more easily. Discover the meaning of information quality, and learn how to evaluate the information you come across. You will also be introduced to the many different ways of organis

9.5 Tables Using a table or just a set of columns can help you to analyse information and ideas. You can vary the number of columns and rows as needed. The following activity provides an opportunity for you to summarise information in a table. 9.4 Mind maps Mind mapping or spider diagrams have become popular in recent years. If you haven't tried this way of making notes, it is well worth a try. When making a mind map, you generally put the central topic in the middle of the page and then arrange the different aspects of the topic around it. However, you can give free rein to your creativity with mind maps. There are no hard and fast rules. Try experimenting with different colours or even pictures if you have artistic skills. Mind maps do g 9.3 Linear notes This is the most common form of note-taking. It involves writing in sequence the points you want to note. As with all note-taking, the aim is to pick out and record the most important points. Avoid simply writing out most or all of the text again. Try to write your notes in your own words as this will help you understand what you have been reading about. Also add a reference to which page(s) of the text your notes refer so you can easily find your way back to the relevant part of the te 9.2 Marking up a text Although you might not think of this as note-taking, marking the text as you read can be a very useful part of the note-taking process. You can do this by using a highlighter pen, by underlining key points or by making notes in the margin. However, try not to overdo it and only highlight important points.
