The relativistic Universe
Thanks to cutting edge technology, scientists can peer deeper into space than ever before. The audio tracks in this album feature Dr Robert Lambourne and Dr Stephen Serjeant of The Open University's Department of Physics and Astronomy. They introduce the origin of relativistic cosmology and share the latest ideas about the structure and evolution of the universe. Einstein’s general theory of relativity predicts the existence of black holes and gravitational waves, and the Cosmic Microwave Back
8.5 Monitoring progress This stage is about keeping track of your progress. Are you tackling your problem-solving activities effectively? How do you know? Could you have done things differently, made use of different tools (such as software packages) or facilities, taken more advantage of tutorials, training sessions or local expertise, or recognised that such support would have helped you? Monitoring your own performance and progress needs practice; try to stand back and look at what you are doing as if you w

Money talks: Trumponomics
Donald Trump's presidential campaign is astounding political analysts and flummoxing economists; and we also look at whether high denomination bank notes are useful only to criminals
Correction: We attribute an analysis of Donald Trump's economic proposals at 2:40 minutes to the Tax Policy Centre, when in fact it is from the Committee for a Responsible Federal Budget. We regret the error.
4.5 Some general results We next establish some general results about Euler characteristics. We start with a theorem that tells us what happens to the Euler characteristic of a surface when we remove an open disc.

The physical attribute of sound that is most closely correlated with loudness is intensity. So loudness is the listener's subjective description of the intensity of the stimulus. As you know, we are not equally sensitive to sounds of all frequencies so perceived loudness of a tone in fact depends on frequency as well as intensity. Two sounds can have the same physical sound pressure levels but if 6.2 The supremacy of EU law Whenever there is a conflict between the provisions of EU law and the provisions of the domestic (national) law of a member state, then EU law will prevail. This is a principle which was developed by the ECJ as the relationship between domestic and EU law is not clarified by treaty provisions. This is an important principle, as it ensures the proper functioning of the EU. If an EU member state had the power to annul EU law by adopting new domestic (national) law which was in conflict with the 1 Making, interpreting and applying rules The aim of this course is to introduce you to the processes of making, interpreting and applying rules. We often think about social rules, most of which are unwritten and which we observe because we have a shared social understanding of what they are. We are now going to think about a different kind of rule. A definition of a rule (as opposed to a habit, custom or role) is shown in Author(s): 3.6 Viewing the data Reverting to the relational database we constructed in Section 3.3, you might wonder what, from the user's point of view, has been gained by creating separate tables for the students and courses. With Table 1 you could see at a glance who was studying what. In the relational database it was har Differences in the neural basis of Chinese and English reading 3.2 Small babies Development continues in the womb until birth, which, in humans, is about 38 weeks after conception. (The often quoted duration of pregnancy of 40 weeks is based on pregnancy beginning on the first day of the last menstrual period.) The duration of the period of development before birth, called gestation, is highly variable. It is not possible to determine its full range in the UK, because medical intervention usually prevents pregnancies going beyond about two weeks after the due date, or te Breakingviews: HSBC worries hit earnings and reputation French Verbs, Part 3 Ordering Fractions | 4th Grade | Khan Academy 5.5 Vibrating string: pitches of notes produced by stringed instruments When a string is bowed, plucked or struck, energy is supplied that starts the string vibrating. The string doesn't just vibrate in one single mode; instead, it vibrates in a combination of several modes simultaneously. The displacement along the string is the superposition of the standing-wave patterns corresponding to those modes. For example, if the string vibrated only in the first and second modes, the displacement at a given instant of time might appear as shown in Author(s): References Have the BRICs Hit a Wall?

This week in the Planet Earth Podcast: Mathew Williams of Edinburgh University and Shaun Quegan of Sheffield University talk about a new earth observation mission recently given the go-ahead by the European Space Agency.
Introduction: Previous functional imaging studies comparing Chinese and English reading have reported that a left middle frontal region is more activated by Chinese reading and the left superior temporal cortex is more activated by English reading (Tan et al. 2001; 2003). We investigated this finding and its interpretation by conducting a functional magnetic resonance imaging (fMRI) study of reading in China and England using monolingual adolescents who spoke Mandarin or English respectively.

As the BRICs falter, a new group of growth economies is emerging, but they have lots of work to do before they are stable enough to become serious players.
