Notched zinc, broken by impact at room temperature
This is a notched zinc specimen broken by impact at room temperature. It has failed by a cleavage mechanism. One can observe the cleavage planes clearly separated by regions of local shear, where the fracture path crosses to adjacent planes. The cleavage planes are atomically flat and are not associated with much plastic deformation. At low temperature metals having b.c.c. and h.c.p structures have insufficient independent slip systems operating and are brittle, fracturing by cleavage.

An introduction to data and information
Ever wondered how a computer processes data into information? This unit will help you to understand the distinction between the two and examines how a computer-based society impacts on daily life. You will learn what computers can do with data to produce information and how computers can be used to work with data and search for it, control machines, and support commercial operations.
An introduction to sustainable energy
The search for sustainable energy will dominate the twenty-first century. This unit provides an introductory overview of the present energy systems and takes a brief look at where the world may find energy in the future – cleaner use of fossil fuels or renewable energy sources?
Weather, Migration and Plants
As students make local observations and analyze Journey North News updates, maps, and data, they should think critically about the relationship between weather and seasonal events. This activity suggests how they might do that.
Mars Reconnaissance Orbiter: The First Months
NASA's Mars Reconnaissance Orbiter (MRO) was launched in 2005 to search
for evidence that water persisted on the surface of Mars for a long
period of time. While other Mars missions have shown that water flowed
across the surface in Mars' history, it remains a mystery whether
liquid water existed long enough to provide a habitat for life.
After a year’s cruise and aerobraking to reach its science orbit in
September 2006, the MRO has begun to study the history of water on Mars
with a suite
The Accidental Guerrilla: Fighting Small Wars in the Midst of a Big One
In the first few years of the post-9/11 era, the established models for fighting ‘small wars' proved distressingly ineffective against resilient insurgencies in Iraq and Afghanistan. As the insurgents fought Western armies to a stalemate, it was clear that a new approach was necessary. Dr David Kilcullen, a former Australian army officer, and one of the world's most influential experts on guerrilla warfare, became a key architect of the West's revamped military strategy. As the seni
Tower O' Power
In this activity, students learn about creating a design directly from a CAD (computer-aided design) program. They will design a tower in CAD and manufacture the parts with a laser cutter. A competition determines the tower design with the best strength:weight ratio. Students also investigate basic structural truss concepts and stress concentrations. Partnership with a local college or manufacturing center is necessary for the completion of this project.
Pea Soup Ponds
In this activity, students will learn how water can be polluted by algal blooms. They will grow algae with different concentrations of fertilizer or nutrients and analyze their results as environmental engineers working to protect a local water resource.
4 Summary of video
The search for new medicinal products is one of the major driving forces behind the development and application of new synthetic methods. This unit focuses on a specific case study, which follows the development of a drug for the treatment of high blood pressure. It is a particularly good example of the application of organic chemistry in the pharmaceutical industry, and illustrates the scientific processes that are involved in the development of any new drug.
The Missing Dimension of Stateness
While Professor Francis Fukuyama’s changing evaluation of the arguments
of his one-time Neocon colleagues has illuminated major issues about
American policy and the war in Iraq, his general thinking about weak
states and foreign intervention has received less attention in
Australia. In this lecture he continues his review of policies and
practices on international aid and the rebuilding of weak, failing and
failed states. As Professor Fukuyama has argued, “state-building is one
