... The Seasons . ... Section #1 Stargazers and Skywatchers described the observed motion of the Sun across the sky, in different seasons of the year. ... If the Earth's axis were perpendicular to the ecliptic, as in the drawings here, the Sun's position in the sky would be halfway between the celestial poles, and its daily path, seen from any point on Earth, would stay exactly the same, day after day. Each point on Earth would be carried around the axis AB once a day. ... The Sun and Seasons . ...

... Very few of us can do something without the feeling that it can be done and done good. So, I want to say several words on the possibility of building the Open society in Russia. ...
