1.4 Decimal places

If you have less than one unit you should put a zero before the decimal point to make it easier for yourself and others to read the value (e.g. you should write 0.4 rather than just .4, as will be explained later in this course). However, how many zeros should you put after the last whole number in the series? For instance, is 0.4 the same as 0.40?

The short answer is that on one level, it is. However, by writing 0.40 we are saying that there are four tenths and zero hundredths,

3.1 A two-fluid model

As was mentioned earlier, a substantial dose of quantum mechanics would be required to provide a full explanation of the properties of superconductors. This would take us too far away from electromagnetism, and we shall therefore restrict our discussion to aspects that can be discussed using classical concepts of electromagnetism.

We shall model the free electrons within a superconductor as two fluids. According to this two-fluid model, one fluid consists of ‘normal’ electron

3.2 QSO spectra

It only became apparent that these quasi-stellar objects were not stars when their spectra were examined. At first astronomers could not interpret their spectra because the spectral lines did not appear at appropriate wavelengths for atoms of any known chemical element. The spectrum shown in Figure 4 provided the

3.3 The London equations

A simple but useful description of the electrodynamics of superconductivity was put forward by the brothers Fritz and Heinz London in 1935, shortly after the discovery that magnetic fields are expelled from superconductors. Their proposed equations are consistent with the Meissner effect and can be used with Maxwell's equations to predict how the magnetic field and surface current vary with distance from the surface of a superconductor.

In order to account for the Meissner effect, the L

The Myth of Millionaire Tax Flight: how place still matters for the rich [Audio]
Speaker(s): Dr Cristobal Young, Ed Miliband MP, Dr Andrew Summers | If taxes rise, will they leave? In his new book, Cristobal Young publishes the findings from the first-ever large-scale study of migration of the world’s richest individuals, drawing on special access to over 45mil US tax returns, together with Forbes rich lists. He shows that contrary to popular opinion, although the rich have the resources and capacity to flee high-tax places, their actual migration is surprisingly limited.

4 Debates on the development of Europe

Not unlike that of earlier conceptions, the new Europe of the early twenty-first century involves a somewhat loose idea of Europe as a geographical entity and a project of European development based on the pursuit and expansion of core values. Early Christian Europe had developed a self-awareness in terms of fundamental religious beliefs and pursued them within and beyond its original territorial base in a series of crusades and related initiatives; the more secular Europe that followed foste

4.1.1 Maps

Many people are fascinated by maps, and most find them useful, though not in all situations. A lone driver, without a map-reading navigator, will find it difficult to use a map. New in-car navigation systems are designed to help such a driver, or one who is without map-reading skills but is able to follow directions.

The remainder of this subsection uses maps to introduce some important terms and concepts. It also examines a navigation system, used both in cars and in hand-held devices,

3.3.1 Summary

  • Claims about who is poor are rooted in shared and contested ideas about the basic necessities of life.

  • The experience of poverty is both relative and relational. It is defined by what people have, and what they can do, relative to the opportunities of others.

  • Poverty carries derogatory meanings, so it does not easily provide a basis for collective identity.

3.1.1 Bonaparte Visiting the Plague-Stricken of Jaffa

First and foremost, Jaffa (like Eylau) contributed to the personality cult of Napoleon, which formed the core of the regime's propaganda. In this respect, however, it is important to note that this painting, exhibited in the Salon of 1804, was actually one of the first military scenes commissioned by the regime to exalt Napoleon in this way. This was largely because it took some time before the propaganda machine needed to organize a large-scale system of official patronage was

15.301 Managerial Psychology Laboratory (MIT)
We function in our personal and professional lives based on knowledge and intuitions. Our intuition that we know a lot is very powerful. But sometimes intuitions are accurate and sometimes they are not; without research, it is hard to tell.

Introduction

Ethics is an established area of academic interest, but it is only fairly recently that the relevance of ethics to Information and Computer Sciences (ICS) started to emerge clearly outside philosophical studies. Professional bodies in Engineering and ICS have begun to require, as a condition for accreditation, the study of ethics-related topics, and, partially in response to these requirements, new pedagogies for teaching and learning these topics are gradually emerging.
