Science appeared for the sake of the need to answer people's questions.

The process of glass formation can not be explained with the help of any of the current tools of solid state physics, the many-body theory or the theory of liquids. If we describe briefly, liquid molten glass upon cooling gradually becomes more viscous until it acquires rigidity.

<strong>Why does not the bike fall on its side?</strong>

Why does not the bicycle fall, until the end is not known. According to the latest assumptions of engineers, a special role in this is played by a special load distribution.

<strong>What did the wow signal mean from the distant cosmos?</strong>

<strong>On August 5, 1977, one of the most mysterious events in the history of space exploration occurred.</strong> The signal originated from the sky region in the constellation Sagittarius, about 2.5 degrees south of the star group Hee.

<strong>In 2012, to the 35th anniversary of the Observatory's signal, Arecibo sent a response from 10,000 encoded tweets in the direction of the alleged source</strong>. However, if anyone received it, it is not known. Until now, the wow-signal remains one of the main mysteries for astrophysicists.
