...star is a very prominent one now and its position can be easily described: It can be seen at about seven or eight in the evening by looking overhead at the brighest star in the zenith and following with the eye about one quarter of the area from that star to the western horizon. The distinguishing points are that it is very bright and is almost exactly in the centre of a triangle of three other stars. More specifically--following along that part of the Fence running from the Co-operative to Massachusetts--if one stands by the first post...
...historical play, Henry V, distinguished among Shakspere's series of historical plays by its atmosphere of peace. Written after the melodramatic Henry VI, King John, Richard II, and others, it represents the highest development of Shakspere's views on war and peace. It was composed in 1599, at the zenith of his creative power, and is his only play of which the date of composition is definitely known...
...classes will assist in making observations on the meteor shower, which will probably be visible at that time. During the evening, the meteors will appear to be coming from the eastern horizon; and towards Sunday morning they will radiate from a point a little to the southeast of the zenith, in the constellation of Leo. This point will rise about midnight. If the weather is favorable, photographs will be taken to determine the height above the surface of the earth at which the meteors first become visible...
...ancient astronomers came to the general idea of the spherical shape of the earth for they observed that as one travelled north or south he found that the position of the pole in regard to the position of the zenith changed. If one travelled south, the pole became farther distant from the zenith, and if north, it became nearer. This then took place either because the earth was round or the pole was an object so near that it might be passed and left behind. But the ancients observed that the stars were very far distant and therefore arrived...
They noticed also, in travelling, the change of the angles between the zenith and pole, and by measuring the distance travelled and the change of the angles they were enabled approximately to measure the circumference of the earth...
