World of Crystals
Breeding, Growth and Structure
What have salt, iron, diamonds and a snow flake in common? At first glance, not very much.
But if you take a closer look, you will recognise one feature they have in common: all these materials consist of crystals.
Angular and also symmetrical shapes are the main characteristics of crystals. Often they have smooth, flat faces and even rectangular edges.

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.
Blogging
The weblog or blog, for short, as a medium is not much older than this century. Blogs came into being in the World Wide Web as ’messages from below’, as web pages from web creators who wanted to share their view of the world with the world. They are short notes, long texts, pictures, videos, which are posted loosely and at random intervals to the world for an undefined public.
