Igneous Rocks Tour
This module is designed to allow students to learn about igneous rocks at their own speed using images of hand samples and rock outcrops in their natural settings. Topics covered include the common igneous rock types, igneous textures, and intrusive rock bodies. Each topic has instructive text and several images. The site also features a self-quiz with 17 questions about 12 hand sample pictures. This site provides useful reference material suitable for high school or introductory college student

3.2 Negative freedom

The concept of negative freedom centres on freedom from interference. This type of account of freedom is usually put forward in response to the following sort of question:

What is the area within which the subject – a person or group of persons – is or should be left to do or be what he is able to do or be, without interference by other persons?

(Berlin (1969), pp. 121–2; see, p. 155)

3.6 Berlin criticised: one concept of freedom?

I've already mentioned that the most important feature of Berlin's article for our purposes is his distinction between negative and positive concepts of freedom: freedom from constraint, and the freedom that results from self-mastery or self-realisation. Most discussion of Berlin's article has also focused on this distinction. Now I want to consider a criticism of the distinction between two types of freedom.

The whole article rests on the assumption that we can make a meaningful distin

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.

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
