Why do products fail and who finds out why? This unit enters the complex world of forensic engineering and examines how scientists analyse product failure. From investigating a ladder accident to determining the reasons behind the failures in medical products, you will understand how the ‘truth’ can be established. View course on original website...

Where does the structure of our body come from? This unit looks at the structure of cells and how proteins are used by both animals and plants to create a framework for cellular growth. You will also learn how a material as fine as spider silk, can exceed the strength of steel. View course on original website...

The human eye is a fascinating and complicated device, but how do digital cameras capture images? This unit examines one of the human–machine interfaces that link optical information to the electronic world. You will learn how the components within a digital camera capture images for electronic manipulation. View course on original website...

Without it we are dead! Water is essential, but what processes must it go through to become fit for human consumption? This unit will guide you through the continuous cycling of water between land, open water surfaces and the sea before moving on to an overview of the water treatment and supply process.

Engineering is about extending the horizons of society by solving technical problems, ranging from the meeting of basic human needs for food and shelter to the generation of wealth by trade. This unit looks at the impact of changes in temperature on a variety of objects and looks at the problem of boiling water. View course on original website...

Engineering is about extending the horizons of society by solving technical problems, ranging from the meeting of basic human needs for food and shelter to the generation of wealth by trade. Engineers see the problems more as challenges and opportunities than as difficulties. What they appear to be doing is solving problems, but in fact they are busy...

This unit looks at complex numbers. You will learn how they are defined, examine their geometric representation and then move on to looking at the methods for finding the nth roots of complex numbers and the solutions to simple polynominal equations. View course on original website...

This extract is concerned primarily with the chemistry that underpins the operation of the three-way catalytic converter that is placed in the exhaust systems of motor vehicles in order to reduce the emissions of primary pollutants: carbon monoxide, oxides of nitrogen and volatile organic compounds, including hydrocarbons. Discussion of the various... View course on original website...
