5.1 Phase and phase difference

In this section I am considering sine waves that have the same frequency, but are out of step with each other.

Suppose we have two detectors at fixed points, A and B. At this moment in time A is in a high pressure region and B in a low pressure region. If we were to look again shortly later B would now in a high pressure region and A in a low pressure region. The pressures at A and B would be out of step with each other. The pressure variation at B is not in phase with that at A. The ex

Writing Creatively for Business
In this session we'll be looking at the sort of things business writers do and that you might be doing. At the end of this introductory session, you should have an idea of the range of purposes underlying written communications for business and not-for-profit organisations, and the wide variety of forms that such writing takes. You'll be trying your hand at a couple of short business writing assignments, and should gain a sense of how working in this area can be creatively challenging and fulfil

Romer on Charter Cities
Paul Romer of Stanford University talks with EconTalk host Russ Roberts about charter cities, Romer's idea for helping the poorest of the poor around the world. Romer envisions a city where the rules about property and safety and contract and so on are rules that allow individuals to flourish in an urban setting in contrast to the cities they live in now where so many aspects of economic and personal life are dysfunctional. Charter cities would be havens for the world's poor and could be created

2.4 Worlds in motion: the importance of flows

‘The sea had welled up suddenly through thousands of tiny holes in this atoll's bedrock of coral.’ Do you recall this passage in Lynas's (2003) account of his first days on Tuvalu in Reading 1A? For me, this gives an impression of the islands being quite literally porous, a solid ground that reveals itself, now and again, to be not so solid after all. Lynas offers this particularly striking example of the island's openness to the world around it as evidence of a growing vulnerability that

CMS.405 Media and Methods: Seeing and Expression (MIT)
This class examines frameworks for making and sharing visual artifacts using a trans-cultural, trans-historical, constructionist approach. It explores the relationship between perceived reality and the narrative imagination, how an author's choice of medium and method of construction constrains the work, how desire is integrated into the structure of a work, and how the cultural/economic opportunity for exhibition/distribution affects the realization of a work. Students submit three papers and t

2.6 Centre and periphery

Here you have considered some of the ways in which the power and authority of the emperor were communicated to the inhabitants of the empire. The full dynamics of the relationship are difficult to reconstruct especially as the view gained is mainly from Rome looking out to the provinces rather than vice versa. It was important for the emperor to appear to be a competent ruler of the empire. It was one method used by his peers and successors to evaluate an emperor's reign. But it is often diff

N. David Mermin, Cornell University: "Spooky Actions at a Distance?" - April 12, 2007
Einstein's real complaint about the quantum theory was not that it required God to play dice, but that it failed to "represent a reality in time and space, free from spooky actions at a distance." I shall use the rhetorical device of a computer-simulated lecture demonstration (a cartoon version of recent experiments in Vienna) to explain both the appeal of Einstein's criticism and the remarkable fact that the "reality" he insisted upon is nevertheless impossible. I will assume no background in q

24 - Retreat from Reconstruction: the Grant Era and Paths to "Southern Redemption"
This lecture opens with a discussion of the myriad moments at which historians have declared an "end" to Reconstruction, before shifting to the myth and reality of "Carpetbag rule" in the Reconstruction South. Popularized by Lost Cause apologists and biased historians, this myth suggests that the southern governments of the Reconstruction era were dominated by unscrupulous and criminal Yankees who relied on the ignorant black vote to rob and despoil the innocent South. The reality, of course, di

4.6 Systems engineering: the recent development of a discipline

The recent development of systems engineering can be dated from two events. First, following the lead of the US Department of Defense and its introduction of standards for contractors, systems engineering was taken up by companies such as Boeing, Lockheed Martin and, in the UK, British Aerospace, Marconi and the Lucas Group. Second, in August 1990, a group of individuals interested in systems engineering met in Seattle (Box 10 – extract from a paper presented at the International Committee
