Kinematics of fluids
This free course examines the basic kinematics of two-dimensional fluid flows. Section 1 introduces the differential equations for pathlines and streamlines. Section 2 introduces a scalar field, called the stream function, which for an incompressible fluid provides an alternative method of modelling the flow and finding the streamlines. Sections 2 ...

Innovation through representation
Innovations are realised through design, and some of the most useful tools in the designer's toolbox are the representations that are used to move from a vague idea, to a concept, and then to a realised product, service or system. This free course, Innovation through representation, explores what innovation is and how representations are used to...

Life in the Palaeozoic
Fossils are a glimpse into the distant past and fascinate young and old alike. This free course, Life in the Palaeozoic, will introduce you to the explosion of evolution that took place during the Palaeozoic era. You will look at the many different types of creatures that existed at that time and how they managed to evolve to exist on land.
