The Paganini Project with Peter Sheppard Skærved
Polymathic and ever-curious British violinist Peter Sheppard Skærved delves into the Library's fascinating Niccolò Paganini collection. Examining posters, playbills, letters, manuscripts and memorabilia collected by Paganini himself, he reveals how the virtuoso created his own mystique as a violinist and musical innovator. From his "Secret Red Book" containing recipes, prescriptions, tour dates, a laundry list and financial notes, to clues about the virtuoso's alleged use of a steel bow, our P

Energy resources: Coal
During the Industrial Revolution half of the world's coal came from Britain. We still rely heavily on it today to meet our energy needs, but now we import more than we produce. Burning it introduces large amounts of gases into the atmosphere that harm the environment in a variety of ways. In this free course, Energy resources: Coal, it will become apparent that the most appealing quality of coal is that there is plenty of it.

Volcanic hazards
This free course, Volcanic hazards, discusses the various hazards posed by different types of volcanic eruption, illustrated by examples from recent eruptions. The discussion is focused around reading Chapter 5 of Teach yourself volcanoes, earthquakes and tsunamis by OU volcanologist David Rothery. First published on Tue, 22 Mar 2016 as Author(s):
Energy resources: An introduction to energy resources
Energy resources are essential for any society, be it one dependent on subsistence farming or an industrialised country. There are many different sources of energy, some well-known such as coal or petroleum, others less so, such as tides or the heat inside the Earth. Is nuclear power a salvation or a nightmare? This free course, Energy resources: An introduction to energy resources, provides background information to each, so that you can assess them for yourself.

2.7 Inferring relationships of common ancestry This clip addresses the question of how one might go about building a tree, or inferring relationships of common ancestry, by recognising evolutionary novelties, or share 3.2 Natural dives The physiology of the diving response can be studied in the laboratory, but investigating the behaviour of a diving mammal in its natural environment can be more of a problem. However, modern physiological techniques have made it possible to record continuously physiological variables (such as heart rate) and information on depth and position during the spontaneous dives in the wild that are part of the animal's normal behaviour. Most such findings show that the majority of an animal's dives 2.4 Staying warm … In this section, you will meet the term ‘thermal conductivity’ and you will be asked to accept that it is ‘a measure of how readily heat flows from a particular material’. You may be uncomfortable about the lack of detailed explanation of how it is measured and of actual values and units. However, at al 7.4 Equilibrium positions and rates of reaction in this unit Section 7 showed that if a reaction is to occur at a particular temperature, two conditions must be fulfilled: its equilibrium constant must be sufficiently large, and its rate sufficiently great. We finish by pointing out how this crucial distinction between the equilibrium constant and the rate reveals itself in Figure 52. The f 7.3 Is the rate of reaction very slow? If the equilibrium position is very favourable, then the reason why Reaction 8.1 fails to occur at 525 °C must be that its rate is very slow. Usually, a reasonable response would be to increase the temperature yet further, but the structure and economy of the car gives us little scope to do this. The alternative is to use a catalyst, which leaves the equilibrium constant unchanged, while speeding the reaction up. Let us look at the changes that take place in the internal energy 7.2.1 The equilibrium constant An expression for the equilibrium constant of a reaction can be put together from the concentrations of the reactants and products at equilibrium. A concentration of a reactant or product is represented by enclosing its chemical formula in square brackets. Thus, the concentration of NO(g) is written [NO(g)]. To write down the equilibrium constant of a reaction, we start with the concentrations of the products. Each one is raised to the power of the number that precedes it in the reactio 6.4 Summary of Section 6 Molecules have a three-dimensional shape. Bulky irregularities in the shape of a molecule around a reactive site can exclude a potential reactant. Such effects are described as steric. A sufficient refinement of the molecular shape in the region of the reactive site can make that site specific to just one particular reactant. Many enzymes operate in this way. The shapes of simple molecules can be predicted using valence-she 4.5.2 Noble gas configurations under stress It is remarkable how many molecules and ions of the typical elements can be represented by Lewis structures in which each atom has a noble gas shell structure. Nevertheless, many exceptions exist. According to the periodic trends summarised in Section 2, the highest fluorides of boron and phosphorus are BF3 and PF5. How
