Origins of Slavery in America
n 1619, the Dutch introduced the first captured Africans to America,
planting the seeds of a slavery system. About 20 years later slavery became legal. This video is a nice overview of how slavery became part of America's life style. It does not tell about slavery in other countries. The video should be reviewed first due to images. (03:01)

2.4.5 Philosophy

This is yet another essentially literary source, so we can be brief. In fact, as in the case of history, its distinction from literature is anything but cut and dried. The only reason we mention it here separately is because we want to make it explicit that almost everything we have said for literature holds for philosophy too. Many varieties of philosophy aim to find absolute truths. In this respect, philosophy is less concerned with particular periods and places than is, for instance, histo

Calculus Limits: A Numerical Approach
In Calculus, the term limit is used to describe the value that a function approaches as the input of that function approaches a certain value. This video explains the two ways to demonstrate Calculus limits: a numerical approach or a graphical approach. In the numerical approach, we determine the point where the function is undefined and create a table of values to determine the value of the variable as it approaches that point. (1:45)

Professor Peter Lambert inaugural lecture: The Priest, the Coup and the Party
In 2008 Fernando Lugo came to power in Paraguay promising a 'new dawn' based on social justice, democracy and greater empowerment of the country's poor but just four years later, with his reform programme in tatters. In his inaugural lecture, Professor Peter Lambert examines the failure of Lugo's reform programme through analysis of both immediate causes and wider factors related to domestic power relations and political culture. This in turn raises questions about the very nature of Paraguay'

1.1 Introduction

Ratios crop up often in official statistics. The government wants the teacher–pupil ratio in schools to be increased to one teacher to thirty pupils or less. The birth rate has fallen: the ratio of children to women of child bearing age has gone down. It used to be 2.4 to 1, and now it is 1.9 to 1. Predictions for the ratio of working adults to retired adults is disturbing. Predictions are, that by 2030 the ratio will be two working adults to every retired person, instead of three to one no

1.2 MOS structures

Carefully designed metal–oxide–semiconductor (MOS) structures are a common building block in digital electronics, primarily intended to form part of a transistor-based switch. However, throughout the active regions of a microelectronic chip there will be secondary MOS structures that arise because metal tracks are insulated from the semiconductor substrate by a layer of oxide; equally careful design is necessary to ensure that these do not form part of a switch. The acronym is a mixture o

6.3.1 Latent heat

The origins of Black's interest in the phenomenon of melting have been the subject of some debate. John Robison remarked, in his edition of Black's lectures, that Black had been struck by the simple fact that snow does not melt instantly on a sunny winter's day nor does a sharp night-time frost cause ponds to form thick layers of ice immediately (Robison, 1803, vol. 1, pp. xxxvi-xxxvii). It is now generally agreed, however, that Black's interest in heat arose from his study of the temperature

8.4 Hinduism in eastern India: religion in Calcutta

The Hinduism of Bengal, as in other regions of India with their own languages and distinctive historical traditions, has absorbed and retained many local elements which make it peculiarly the Hinduism of Bengal. The city of Calcutta has exerted its own considerable influence upon the surrounding region. Calcutta, the capital of West Bengal, was founded in 1690 originally as a British trading post on the Hugli, a stretch of the Ganges (or Ganga), a river sacred to Hindus (see Author(s): The Open University

5.4 A dimensional model of religion

Given the problems of devising a succinct definition of religion, some contemporary scholars have produced broader profiles of religion without claiming to identify one distinguishing characteristic. One example of this kind of approach is the seven-dimensional model of religion proposed by Ninian Smart, a specialist in the study of world religions. Smart argues that, if his model is adequate, ‘then we do not need to worry greatly about further definition of religion’ (Smart, 1989, p. 21)
