Rupinder Brar on Relativity, Einstein, and How to Stay Young
Rupinder Brar lectures on the topic of Einstein's special relativity theory and it's explanation of time dilation and simultaneity. The lecture is entitled Relativity, Einstein, the Speed of Light and How to Stay Young.
Learning outcomes By the end of this unit you should be able to: explain the meanings of the emboldened terms and use them appropriately; describe the behaviour of wave packets when they encounter potential energy steps, barriers and wells; describe how stationary-state solutions of the Schrödinger equation can be used to analyse scattering and tunnelling; for a range of simple potential energy functions, obtain the solution of the time-independent Sc
Numbers
This unit will help you understand more about real numbers and their properties. It will explain the relationship between real numbers and recurring decimals, explain irrational numbers and discuss inequalities. The unit will help you to use the Triangle Inequality, the Binomial Theorem and the Least Upper Bound Property. First published on Wed, 2
5.6 Casting defects The first class of defect would have been inferred from examination of fractures in the cast-iron columns, where, for example, the wall thickness would be exposed for measurement. However, some of the casting defects he mentioned in his testimony – and which were to gain some notoriety both in the popular press accounts of the enquiry and in later accounts – are difficult to describe in detail because he did not specify where they were found in the debris, or how exactly they had contribu
8.8 Hinduism as ‘a world religion’: a more recent understanding Traditionally, as we have seen, a Hindu was someone born to Hindu parents and into a caste with its appropriate dharma. The link between religious practice and a whole way of life bound the individual into a community from birth. Regional factors, parentage and caste affiliation largely determi

3.3 Architecture Printing and publishing, then, had their connections with the Enlightenment programme. Architecture too was related. The Adam family of architects (the father and his two sons) moved in the Edinburgh circle of the intellectuals. The young Robert Adam, for example, attended both McLaurin's mathematics lectures and Monro's anatomy lectures at the university, and his home life was enlivened by regular visits from the leading lights of the city. As one contemporary described the household, in a r
Business cultures
Why are we studying ‘business cultures’? Culture is a metaphor which can be used to explore the identity of a business. It is about how others see the business, but also how the individuals who work there understand it. Culture offers us a powerful insight into the business and what it is like to work within it.
6.4 Prospect theory Kahneman and Tversky (1979) developed ‘prospect theory’ to describe this combination of risk and loss aversion. This suggests that whether an individual is risk seeking or risk averse will depend on where they are in relation to a personal reference point. The reference point divides the area where they feel as if they are in loss from the area where they feel they are in gain. This point is not usually zero, and will change over time. For example, a professional financial trader who is p
6.2 A rational-economic perspective on risk A rational-economic perspective generally represents risk as a combination of the expected magnitude of a gain or loss, combined with some probability distribution of anticipated outcomes. Economic ideas of risk behaviour are founded largely on expected utility theory. Expected utility theory predicts that investors will always be risk averse. The shape of the utility curve (utility plotted against increasing wealth) is such that utility increases with wealth, but at a declining rate. This is
5.6 A way of dealing with social pressures: decoupling Organisations often deal with these social pressures by decoupling responses to these different pressures. The need to appear legitimate in the eyes of important constituencies is met by actions and practices which have a purely ceremonial character: they are done for the sake of appearances and not with any real engagement. The example in Author(s):
Introduction ‘Environment’ is one of the more popular words in the management lexicon, most generally understood to be referring to ‘something outside’. But common usage today often interprets the Environment (with or without the capital ‘E’) as referring to the planetary ecosystem. On that basis the Environment includes such things as global warming, the state of the ozone layer, deforestation and the means of energy generation. Organisations need to coexist with their environment, responding
3.1 Evaluation while developing the vision A project is often shaped through discussion among those developing the vision and direction of the project. They may agree in general terms about what is to be achieved, but have to make a number of choices before deciding how to proceed. It may be important to allow time for different views to be heard and considered, and for attitudes to change and – hopefully – converge. Learning outcomes By the end of this unit, you should be able to: identify your objectives; assess what you have to offer; balance these against a practical framework of your personal circumstances; explore a range of reference sources to select what is most relevant; prepare an action plan, including evaluation of achievements; produce ongoing strategies to develop your voluntary work; understand employersâ Introduction This unit provides a further opportunity for you to take notes using audio visual material. Before continuing to watch the clips, please ensure that you have already worked through DD208_1. Use the advice and guidance that you learnt in DD208_1 to take notes on the video clip presented in this unit. Use the note taking techniques you learnt, and remember that your notes need to reflect what each video is showing. You need to identify the nature of the debates and the arguments and ident 1 Learning from audio visual text You might think that learning from audio visual sources is very different from learning from written sources, yet, somewhat surprisingly, it is much the same. As you may be familiar with watching videos mainly for leisure, this section will help you to think about how you can turn the familiar, but usually passive, process of watching a video into the active process of learning. Watching the video clips will involve the skills of engaging with the material and making sense of it for yourself, The 1990s wedding photograph Now let us look at the 1990s image. This too depicts a wedding. What makes it different from that of 1.4.1 PROMPT There is so much information available on the Internet on every topic imaginable. But how do you know if it is any good? And if you find a lot more information than you really need, how do you decide what to keep and who to discard? In this section we are going to introduce a simple checklist to help you to judge the quality of the information you find. Before we do this, spend a few minutes thinking about what is meant by information quality. Introduction This unit, which contains material from the current Open University second level Politics course DD203 Power, Equality and Dissent, is pitched at the intermediate level. It should take you about 8 hours to study if you attempt the recommended exercises and make summary notes of its key points. Doing so will allow you to practise the crucial academic skill of summary and précis – extracting the gist of an argument – which will be of particular help if you go on to study in related 6.5.2 AlphaWorld AlphaWorld does not exist in space. It is a purely digital world, existing in the memory of a powerful computer, or group of computers, somewhere in the physical world. In the jargon of computer science, it is a virtual world, where Virtual’ is a term used to describe any entity that does not really
