### Newtons Movement

In this specific law not the nature of the force that builds on a body; or it can be the friction force or the one that the wind exerts on the candles of a boat, we also found that if the acceleration is known a body, it is possible to be calculated his speed and its displacement like function of the time. Until the moment three forces have been identified in the nature that essentially defer to each other by their origin and magnitude. I hope that educational you and students of the causes find more than three. 1) The gravitational force, 2) the electromagnetic force, the 3) and nuclear forces.

we consider the movement of a body that falls freely. direction of movement agrees with the direction of the field. As the field strenght comes given by the expression. G= F/M, F = MG. And in such conditions, the body falls under the action of a constant force, which implies that their movement uniformly is accelerated.

When the body is sent vertically upwards, it acts on the force exerted by the field of gravitation that consequently prints an acceleration to him in opposite direction of its movement and, the speed of ascent of the body is falling progressively, until being annulled. And the body is in its peak altitude since then the movement changes of direction and the body falls. You can observe that These forces can be appreciated by the consequences that the movement produces. Without the movement the forces serian totally null, because even though the bodies are on a surface, the gravity force prints a movement on such bodies which tend towards the Earth.

The medieval Pythagorean tradition, the hermetismo and the cabalismo had added an immense wealth, extending the universal harmonias, to the quarrel of parallelism. This intense complexity contributed as key to understand the nature, affirming and preparing the land for the mathematical thought on the universe. Another present important characteristic in the renascentista magic is the cult to the sun? the call ‘ ‘ heliocentrismo’ ‘. The cult to Hermes Trismegisto tended to attribute to the Sun the position of ‘ ‘ second deus’ ‘ , as strong religious symbol. This perception fortified the position of astro as a primordial image of the ideas, conceived as esplendor intelligible. The copernicana revolution was presented under the religious atmosphere, which considered it as an act of contemplation of in agreement world revelation of God, despite the same one has been carried through on the basis of a huge mathematical calculation. According to Yates, the copernicana discovery came to the light with the blessing of Hermes Trismegisto.

The new vision of world, as a new panorama of references and attitudes, proposal for the hypothesis elaborated for Coprnico was based on an intense distinction given to the Sun, having induced that thinker to undertake mathematical calculations, under the idea of that the Sun was really in the center of the planetary system. This revolutionary interpretation represented the capacity of intervention and experimentation human beings as one practical rational? attitude that substituted the medieval contemplativa ethics gradually. In this context, Giordano Bruno, intensely religious hermetista, considered the Sun, of the copernicana theory, closely on to the solar magic of Ficino. On the basis of analysis Yates the French, the use of the copernicana theory made by Bruno demonstrates, of impressive form, as they were uncertain and moving the borders between genuine science and the hermetismo during the Renaissance. This sensible ‘ ‘ hibridismo’ ‘ the magic of the Renaissance enters and the primrdios of modern science are reflected of a great transformation in the way to see the man and the world.

### David Thoreau

Henry David Thoreau: " Blessed the mortal who does not lose a little while of the fugitive life in remembering. &quot the past; Yes, something very great is going to happen when the clock marks the twelve and we change by day. Still more in seasons when besides day we changed of month and year. And what is going to happen? One releases list of facts and events can appear in a period of three hundred sixty and five days and is normal that the faith takes to us to be optimistic but it is just also that everyone makes its own predictions. Pedro and Juan are two personages of my district. Pedro is optimistic and it always watches the positive side of the things. The friendly have not vacillated looking for nickname to him: they call Dreamy.

Juan, however, is pragmatic and realistic; sometimes it arrives at the end of the negativismo and their calculations on the morning sometimes are apocalyptic. The friendly already have nickname to him: the kill-joy calls . According to the form in which Juan sees the subject the next one will be a beautiful year in whom it will leave the sun for all again and it will shine the same for those of here and those of there; God will be with the open arms in the hope that their children recognize their magnificencia and infinite mercy; there will be roses in the garden of the blacksmith will be born sunflowers in the balcony from the industralist; in the green forest the maanero song of the birds will be listened to and the murmur of waters will give account of which the river has life and it gives his waters to him to the sea so that the sea, along with the sun, causes rain and rain returns to generate life.
