Producing Penicillin
This video segment adapted from A Science Odyssey tells how two
scientists, Howard Florey and Ernst Chain, used the research findings
of Alexander Fleming to turn a natural compound, penicillin, into an
effective treatment for bacterial infections. Their tests in mice and
later in human patients demonstrated penicillin's ability to cure such
infections. After U.S. drug companies figured out how to mass-produce penicillin, its reputation as a "miracle drug" was e
Inventions of War - the Jeep
During World War II, General Dwight Eisenhower called the Jeep one of America's most important weapons. This short video describes the origins of the original Jeep and even addresses how it received it's funny name! (U.S. soldiers shortened the term "general purpose vehicle" to "GP" then "Jeep") Run time: 2 minutes
17.433 International Relations of East Asia (MIT)
The aim of this lecture course is to introduce and analyze the international relations of East Asia. With four great powers, three nuclear weapons states and two of the world's largest economies, East Asia is one of the most dynamic and consequential regions in world politics. During the Cold War, East Asia witnessed intense competition and conflict between the superpowers and among the states in the region. In the post-Cold War era, the region has been an engine of the global economy while unde
2.016 Hydrodynamics (13.012) (MIT)
This course covers the development of the fundamental equations of fluid mechanics and their simplifications for several areas of marine hydrodynamics and the application of these principles to the solution of engineering problems. Topics include the principles of conservation of mass, momentum and energy, lift and drag forces, laminar and turbulent flows, dimensional analysis, added mass, and linear surface waves, including wave velocities, propagation phenomena, and descriptions of real sea wa
2.094 Finite Element Analysis of Solids and Fluids (MIT)
This course presents finite element theory and methods for general linear and nonlinear analyses. Reliable and effective finite element procedures are discussed with their applications to the solution of general problems in solid, structural, and fluid mechanics, heat and mass transfer, and fluid-structure interactions. The governing continuum mechanics equations, conservation laws, virtual work, and variational principles are used to establish effective finite element discretizations and the st
Still banning that Bomb: Thinking about nuclear non-proliferation and disarmament
Friday 31 July, 3.30-5.00pm Seminar Room 1.03, Ground Floor, Hedley Bull Centre, Garran Rd, ANU campus Ron Huisken is Senior Fellow at the Strategic and Defence Studies Centre, Australian National University. He spent a number of years at the Stockholm International Peace Research Institute and the UN Centre for Disarmament Affairs before joining government (1981-2001), predominantly the Departments of Foreign Affairs and Trade and of Defence. He returned to academia in 2001 with research intere
Bi 10, Sn 90 (wt%)
Low concentration of bismuth - there are two components - higher bismuth (light coloured because bismuth has a larger atomic mass than tin) and low bismuth (grey).
The Viking Age: England and Francia
Scandinavians, popularly known as Vikings, began to explore and settle in Europe from the ninth century. Contemporary Christian writers voiced their dismay at what they saw as the sudden eruption of these savage pagans into their area. Commentators since, down to the 20th century have largely echoed these writers' views, sometimes portraying the Scandinavians as mindless thugs led by psychopaths. In a period when savagery in warfare was commonplace, the Vikings have been placed by some in a spec
Doing the right thing: corporate social responsibility in a global marketplace
Globalisation, mass consumer awareness and public accountability are all factors in persuading companies to adopt ethical policies. As companies become more accountable not only for their own actions but for those within their supply chain, they have to adapt to ensure success within the context of the global society they operate in.
Professor Jeremy Moon (Professor of Corporate Social Responsibility at the University of Nottingham Business School and Director of the International Centre for Co

Two Particle Elastic Collision Model
The EJS Elastic Collision Model allows the user to simulate a two-dimensional elastic collision between hard disks. The user can modify the mass, position and velocity of each disk using the sliders. Both disks are draggable and the center of mass is shown a a cross in the simulation.
Greenland's Receding Ice
After Antarctica, Greenland's ice cap contains the second largest mass of frozen fresh water in the world. Based on new research using NASA's airborne laser altimeter, scientists have identified pronounced thinning of Greenland's ice cap. This new research indicates enough ice loss to cause a measurable ...
Prosperity and Thrift: The Coolidge Era and the Consumer Economy, 1921-1929
Prosperity and Thrift: The Coolidge Era and the Consumer Economy, 1921-1929 assembles a wide array of Library of Congress source materials from the 1920s that document the widespread prosperity of the Coolidge years, the nation's transition to a mass consumer economy, and the role of government in this ...
Calculating Relative Air Mass
The purpose of this activity is to introduce students to the concept of relative air mass and demonstrate how solar elevation angle affects the intensity of sunlight that reaches an observer on the ground. Students work in teams to calculate air mass using simple geometry. Teacher background materials are included.

Why do black holes have such strong gravity?
This is a live video chat. The narrator was asked, “Why do black holes have such stronger gravity than the stars they formed from?” Here's the answer, gravity depends upon two things, the mass of the object and how far away you are from it. The mass of a star when it collapses the core forms a black hole, so now you can get closer to it and the gravity draws you in. Video is somewhat confusing - the narrator speaks fast and may be hard
Call for Papers for OCW Consortium Global Conference 2011 The OpenCourseWare Consortium invites session proposals for its 2011 global conference, Celebrating 10 Years of OpenCourseWare. The OpenCourseWare Consortium is a worldwide community of universities and organizations committed to advancing OpenCourseWare and its impact on global education. The OpenCourseWare movement has grown significantly over the last decade; today there are 13,000 courses published by 150 universities.
