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.

Learn moreBionics
Humanity’s achievements in engineering have always been admired. This applies to antiquity’s Seven Wonders of the World as well as to the architectural masterpieces of modern times, such as the Eiffel Tower. The ideas of architects, physicians, mathematicians, chemists, engineers and technicians often have their origins in nature. Nature offers a huge reservoir of materials, which have proven their worth by permanent adaptation over millions of years. However, scientists do not just try to copy nature but strive to understand its principles and constructions and make them technically applicable in a modified way. Biology and technology have merged to the scientific discipline of BIONICS. Why can birds and insects fly? How do creatures live in the water without getting wet? Why is the blue morpho butterfly bright blue without the help of a colorant? Why is the lotus leaf always clean? Which building materials are there in nature? These and many more questions are answered in this DVD! Furthermore, the film gives a detailed illustration of how science implements and reconstructs nature’s ideas and makes them usable for us.
Learn morePreußen II
Dieser zweite Teil unserer Filmreihe über Preußen berichtet über die Politik des letzten preußischen Königs und späteren deutschen Kaisers Wilhelm I. Vom Aufstieg zum Deutschen Kaiserreich bis hin zu Preußens Untergang. Die Auflösung Preußens nach Ende des 2. Weltkrieges setzte einen Schlusspunkt unter eine Jahrhunderte alte wechselvolle Geschichte. Der Name Preußen ist untrennbar verbunden mit Aufklärung und Toleranz, verkörpert etwa in Friedrich dem Großen, verbunden aber auch mit Militarismus, Maßlosigkeit und Selbstüberschätzung Wilhelms II. Das Nachdenken über Preußen stand in den letzten Jahrzehnten im Schatten der hitzigen Debatten über die deutsche Geschichte.

About 150 years lie between the creation of these pictures: on the one hand, the absolute ruler of France Louis XIV, who reigned from 1643 to 1715 and on the other hand, George Danton and Maximilien Robespierre, two distinguished representatives of the French Revolution after 1789, who decided the fate of France. What had happened that the leaders of their country had themselves represented in such different ways? Here the radiant, glorious prince, clothed in precious robes, in front of a legendary background – there the plainly dressed men at their desks with pen and ink as attributes of the educated citizen.
Learn moreSecond World War I
When, on 1st September 1939, the German Wehrmacht unleashed the Second World War with the attack on Poland, nobody could have visualised what immense suffering and gigantic destruction would descend on mankind during the following six years. More than 57 million people, including almost 27 million Russians, paid for the German quest for world domination with their lives. Incited by populist ideas, almost an entire nation enthusiastically went to “all-out war”, thus plunging the world into the second great disaster of the 20th century. But shouldn’t people have known better considering that the First World War had only just been 21 years before?

Learn moreAluminium II
The metal aluminium is growing in importance because of its specific properties and manifold application possibilities. This DVD deals with the industrial production of aluminium as a raw material, its processing and the manufacturing of alloys for the finished product. Starting with the raw material aluminium oxide the functioning of an electrolytic cell is demonstrated and explained. Alumina, white and powdery, is melted with great expenditure of energy, and by means of electrolysis converted into aluminium with a degree of purity of 99.9%. As aluminium oxide would not melt before a temperature of over 2,000°C is reached, the mineral cryolite is used as a solvent. The various alloys change the properties of aluminium and are produced according to precise formulations. The alloy is cast into blocks and bars that serve as primary material for processing plants. The responsible handling of resources underscores the importance of recycling. Aluminium is resilient and versatile.
