already calculating movements of the moon, Regiomontanom product, right the first time made it possible to determine the position of the American coast that Columbus is known, he took first for the East Asia and India.Using the data Regiomontanus, Amerigo Vespucci near the mouth of the Orinoco made observation of the coating on the Mars moon calculation Regiomontanus referred to the meridian of Ulm, the coating must have happened during the night, while on the coast of South America, it was observed in the early evening.
Using the difference of the local time and the time that was given to Ulm, it was possible to determine the longitude of the South American coast with respect to the meridian of Ulm.This calculation is then finally forced to abandon the idea of new supplies in East Asia and has shown that they are in the new part of sveta.Luna In ancient astronomy ...
In astronomy, as is known, the position of places on the earth's surface is replaced by the position of the pointits zenith on the surface of the celestial sphere.Zenith Point on the land is determined by an extension of the plumb line (easiest with a plumb made of yarn) or a direction perpendicular to the liquid surface at rest.On the sea, where a plumb line or surface of the liquid may not be in a state of rest owing to swing the ship zenith point defined as the point equidistant from all points gorizonta.Esche sea in ancient times people knew that the moon is in the sign of the zodiac, the Moon in Capricorn, Moonin Leo ....
smallest measuring the angle or arc between the edge of the solar disc and the horizon of what can be achieved with relatively simple tools, easy to get and the distance of the center of the solar disk from the zenith;This takes into account the phenomenon of so-called lowering the horizon, as it was mentioned when considering the sphericity of the earth.Produce two such measuring distance of the sun from the zenith to what some of the various provisions of the sun relative to the horizon and the countries of the world, one example., Produce up to half a day, the other about half a day.
