Falling Water
Students drop water from different heights to demonstrate the conversion of water's potential energy to kinetic energy. They see how varying the height from which water is dropped affects the splash size. They follow good experiment protocol, take measurements, calculate averages and graph results. In seeing how falling water can be used to do work, they also learn how this energy transformation figures into the engineering design and construction of hydroelectric power plants, dams and reservoi

Eliminating Nuclear Weapons
The Rt Hon Sir Malcolm Rifkind MP on how, in the 21st century, nuclear weapons pose a greater danger than ever before and their possession is less necessary. The time has come to forge agreement on a process of multilateral disarmament. Achieving an end-state of "zero" has emerged as an important policy goal for a number of 21st Century challenges. The most prominent example is the "Global Zero" campaign to eliminate nuclear weapons. Yet, in a century of globalization, when the life of every ind

Who's the Boss. An exploration of the ongoing tug-of-war between fairness and flexibility in the Aus
When Labor swept to power in 2007 it carried a clear mandate to bury the Howard government’s controversial Work Choices reforms. Its Fair Work legislation, which took effect in July 2009, was eagerly anticipated by those seeking a more equitable balance between employee rights and employer flexibility. But 8 months on, controversy remains. Some say Fair Work delivers. Some say it’s little different. Others, including Opposition leader Tony Abbott, say it goes too far. So how has Fair Work c

Berlin Airlift
This video is accompanied by text. "Twenty years after World War I, Germany was able to rebuild its economic and military might and target its weaker neighbors. Following World War II, America and its Western European allies were determined to prevent Germany from regaining its power. With the blessing of their allies, Britain, France, and America controlled their West German sectors in a way intended to keep Germany impoverished, economically weak, and unable to pose a threat. By March 1948, th

The energy carried by ocean waves derives from a proportion of the wind energy transferred to the ocean surface by frictional drag. So, ultimately it stems from the proportion of incoming solar energy that drives air movement. Just how much energy is carried by a single wave depends on the wind speed and the area of ocean surface that it crosses; wave height, wavelength, and therefore wave energy, are functions of the distance or fetch over which the wind blows. This unit considers the power

Cooperative Concurrency for a Multicore World
Multi-threaded programs are notoriously prone to unintended interference between concurrent threads. To address this problem, these lecture presenters argue that yield annotations in the source code should document all thread interference, and they present a type system for verifying the absence of undocumented interference. Well-typed programs behave as if context switches occur only at yield annotations. Thus, they can be understood using intuitive sequential reasoning, except where yield anno

A Quick Shave and Brush-Up (1900)
Like G.A. Smith's earlier Old Man Drinking a Glass of Beer (1898), A Quick Shave and Brush-Up is a vehicle for the Brighton comedian Tom Green, whose various grimaces when shaving and grooming himself constitute the entertainment. It's also a record of a time when cut-throat razors were a standard part of a gentleman's toiletry kit.
