In 2006, the group of Californian theoretical physicists has made an interesting prediction, according to which “sandwich” of the semiconductors with a thin layer of mercury telluride (HgTe) in the middle the electrons will behave in a very unusual way, showing the spin Hall effect. In 2007 the corresponding sandwich was made by experimental physicists from Germany. And they find in it exactly what was predicted by their counterparts from California.
How often do you before the pass of an important project, exam, conversation with your parents or visit to the dentist (when the tooth is aching) find a host of other, more ordinary occupations, that are absolutely not related to the main case?

People got used to such large-scale changes as the redrawing of the continents or climate that occur slowly. It is difficult to assess them by one generation, and sometimes just to see them. However, there is a discovery: a grand event – the upheaval of the magnetic poles – maybe even for a man almost instantly. And such a focus home planet can wrap up before our very eyes.
Modern electric motors are complex mechanical devices that help people in solving various production problems. Without the electric motor it is hard to imagine even the simplest form of electrical equipment, which is protecting the interests of the progressive people. At first, people discovered the inexhaustible sources of electrical energy. Then, using the electric motor they made the electricity to perform time-consuming work. Today, electric motors are an essential part of any electrical equipment. Continue reading
In the Middle Ages (V – XVII) the image of Western society, its culture, pedagogy and education changed significantly compared to the ancient era.
