The Wheel
Invention and Development
One of the inventions that have brought humanity forward is the wheel.
It is the key to the technical and cultural development of mankind.
Without wheels we would get nowhere – in the true sense of the word. And it has been like that for about 5,500 years.
Whereas the wheel was very heavy and, in addition, simply constructed at the beginning of its development because it was entirely made of massive wood, it is a complex building component or machine element with a wide range of applications today.

Stalking
n Germany, 12 % of all federal citizens are pursued by a stalker once in their lives. And not only celebrities are among their victims! Everyone may be confronted with such a situation.
Product Piracy
Counterfeiting takes place in almost all economic sectors – textiles, watches, car parts, machine parts, tools, accessories, software and medicines. Some counterfeits are easy to recognise, others are so well-executed that even experts have difficulty distinguishing between original and imitation. This DVD covers the development of a product from idea to manufacture. Once a product has become a trademark, product pirates appear on the scene.
