Fluids and Viscosity
Be it the honey on our breakfast toast, the water from the tap or the air surrounding us – they all have one thing in common: in a physical sense they are fluids.
The Otto Engine
This DVD offers an insight into the historical birth of the Otto engine and also describes its latest version – the hybrid engine. In addition, other engines of the future are covered. The life and achievements of Nikolaus August Otto are dis- cussed, with all his successes and failures, from his first en- gineering attempts when reconstructing the Lenoir engine to the presentation of the “atmospheric gas engine” on the Paris World Fair through to his cooperation with Gottlieb Daimler and Wilhelm Maybach. The mode of operation of the Otto engine is explained to the pupils in detail, also with the help of a variety of animations and diagrams. The DVD goes into the four strokes of intake, compression, power and exhaust as well as the Otto engine as energy converter. Crude oil is one of our most important sources of energy. Besides outlining the evolution and processing of crude oil into fuel, this DVD puts emphasis on the increasing shortage of global crude oil resources. Alternative propulsion sources like hybrid engines as well as hydrogen-fuelled or gas-fuelled vehicles offer an environmental-friendly vision for the automobile’s future in times of global climate change.
Gravity
Gravity is the force that pulls something to the ground. It ensures that everything falls downwards. Like every force, it has a direction, namely towards the centre of the celestial body. The film vividly shows the development of the law of gravity from Isaac Newton through the further development by Albert Einstein, who described that gravity not only causes bodies to attract each other, but also causes space to curve around a body. Space and time are no longer absolute, fixed quantities, but changeable.
