6.2 Do supermassive black holes really exist?
The field of active galaxies is recognised as one of increasing importance. But how do we know there are different kinds of galaxy? What are active galaxies? How are they powered? This unit examines the different types of active galaxy and looks at the crucial role of the active galactic nucleus and the energy source at its heart.

Introduction
Managing eutrophication is a key element in maintaining the earth's biodiversity. Eutrophication is a process mostly associated with human activity whereby ecosystems accumulate minerals. This unit explains how this process occurs, what its effects on different types of habitat are, and how it might be managed.

Superconductivity
The fascinating phenomenon of superconductivity and its potential applications have attracted the attention of scientists, engineers and businessmen. Intense research has taken place to discover new superconductors, to understand the physics that underlies the properties of superconductors, and to develop new applications for these materials. In this unit you will read about the history of superconductors, taking a brief look at their properties. You will also learn about modelling the propertie

AlgTop9: Applications of Euler's formula and graphs
We use Euler's formula to show that there are at most 5 Platonic, or regular, solids. We discuss other types of polyhedra, including deltahedra (made of equilateral triangles) and Schafli's generalizations to higher dimensions. In particular in 4 dimensions there is the 120-cell, the 600-cell and the 24-cell. Finally we state a version of Euler's formula valid for planar graphs. This is the ninth lecture in this beginner's course on Algebraic Topology, given by Assoc Prof N J Wildberger at UNSW

Busing for Integration vs. Neighborhood Schools
This lesson plan will introduce students to the political, social, and economic issues surrounding school desegregation using oral histories from those who experienced it firsthand. They will learn about the history of the "separate but equal" U.S. school system, the 1971 Swann case which forced Charlotte-Mecklenburg Schools (CMS) to integrate, and the recent decision to discontinue busing for racial integration in Charlotte-Mecklenburg. They will compare and contrast neighborhood schools with s

Criminal violence in Cambodia: An historical perspective
Empirical studies and theoretical analyses of long-term trends in criminal violence have been done in western countries but rarely in other parts of the world. The research conducted by Professor Broadhurst and Dr Bouhours attempts to fill this gap through an examination of the evolution of criminal violence in Cambodia from the start of the 20th century to the present. However, different sources and methods of criminal data recording were used between 1900 and 2008. The diversity of the sources

02 - The Universal Principle of Risk Management: Pooling and the Hedging of Risks
Statistics and mathematics underlie the theories of finance. Probability Theory and various distribution types are important to understanding finance. Risk management, for instance, depends on tools such as variance, standard deviation, correlation, and regression analysis. Financial analysis methods such as present values and valuing streams of payments are fundamental to understanding the time value of money and have been in practice for centuries.
