Lernstift Digital Pen Based on Linux

Lernstift digital pen notifies the user about all cases of misspellings. The pen works on the basis of Linux. Special sensors track the movement and allow to detect errors, and in case of their detection comes vibrating signal. Lernstift works in two modes: Calligraphy Mode and Orthography Mode. In the mode of calligraphy pen notifies the error in calligraphy, and in the orthography mode identifies spelling and grammar errors. There are two varieties of digital pen. So, the first generation of devices should appear in the middle of 2013. It will be handle with motion sensors and the system, to identify the words.

Unusual Galaxy Photographed from Gemini Observatory

Astronomers from Observatory “Gemini” received the most detailed to date image of the unusual galaxy NGC 660, relating to a rare class of polar galaxies. The galaxy NGC 660 is located at a distance of 40 million light years from Earth near the constellation Pisces. It is as if two separate star clusters: the spiral and lenticular. Such galaxies are called polar – they rotate the outer ring over the poles of the internal cluster. In addition, NGC 660 is the only other known polar galaxies in which the center has an old lenticular congestion. All polar galaxies are a result of the interaction of two separate star clusters. Some of them can be formed by the collision of two galaxies formed (for example, a galaxy can be formed by a merger in the future, with the Milky Way Andromeda).
