2.2 Multiplication by a scalar
Attempts to answer problems in areas as diverse as science, technology and economics involve solving simultaneous linear equations. In this unit we look at some of the equations that represent points, lines and planes in mathematics. We explore concepts such as Euclidean space, vectors, dot products and conics.

Introduction

A fair return on investment is defined as one that compensates the investor for the risk incurred in making the investment – neither more nor less. Conversely, an excess return is one that over-compensates the investor for the risk incurred. Investors want to avoid investments that pay less than a fair return, while borrowers want to avoid paying an excess return. In this unit we shall:

  • define more precisely what we mean by ‘risk’ in

Republican Law, 1770-1830

Recorded on Monday, March 21, 2011.

This Chancellor's Chair Lecture addresses the expressive legalism of the American Revolution and explains how it turned into a legal culture that ceased to stand in imaginative solidarity with “the people themselves.” Republican law lived in a contradiction between a revolutionary people imbued with law as imaginative possibility, and a constituted polity whose law defined the limits of imaginative political action. As the republic matured, the

1 Barriers to a strategic view

Marketing communications is not always accepted as having strategic importance in organisations. This unit examines some of the reasons for this, before exploring some recent arguments in favour of a strategic role for marketing communications.

One reason for seeing marketing communications as tactical rather than strategic is that much of its development and execution has been outsourced to marketing services agencies offering a range of specialisms (such as design, creative consultanc

ACE Mission - Fusion and Nucleosynthesis
This educational brief explains the idea that nuclear fusion is thought to be the mechanism by which virtually all of the elements around us are created. Topics include the proton-proton cycle, the carbon-nitrogen-oxygen cycle, and endothermic reactions in supernova explosions. There is also a discussion of the Advanced Composition Explorer (ACE), a spacecraft intended to study the origin and evolution of the elements produced by our Sun.

An Uncertain Glory: the economic and social condition of modern India [Audio]
Speaker(s): Professor Amartya Sen | When India became independent in 1947 after two centuries of colonial subjugation, it immediately adopted a firmly democratic political system, with multiple parties, freedom of speech and extensive political rights. The famines that had been so common in the colonial era disappeared, and steady economic growth replaced the almost complete stagnation characteristic of the long rule of the Raj. The growth of the Indian economy, which has quickened over the last

Hydrophilic Interaction Chromatography, HILIC/SEC, HILIC/SXC
This site provides good background and operational parameters for the use of a specific type of chromatography, hydrophilic interaction chromatography. Pedagogical value, however, is probably only directed toward a graduate/advanced course in separations. This document provides a very clear explanation of operational parameters and mode of operation for HILIC. Very readable!

3.4 Variation
In this unit, we describe the theory of evolution by natural selection as proposed by Charles Darwin in his book, first published in 1859, On The Origin of Species by Means of Natural Selection, or The Preservation of Favoured Races in the Struggle for Life. We will look at natural selection as Darwin did, taking inheritance for granted, but ignoring the mechanisms underlying it.

Mutualistic relationships in nature
Many organisms depend on other organisms for survival. Mutualism is when two organisms have a relationship in nature and each benefits from the relationship. Pollination and lichens are the best examples of mutualism.
