The universe of the circumference

Greetings again with you this navigator immersed in the seas of the philosophy of the knowledge of the circumference and his diversity of approach in his application, considering them to be different options that we take as human beings, we have many needs, which at the same time are small satisfaction that we have, that way happen with the knowledge and more when we speak the study of the science, with an absolute reason we come to an infinite way where the science treats or chases to settle his nature and with her the origin of his ideas, for them the application of the circumference is present in a big scale of use for the knowledge and in ours lives.

Sphere
what can be called a metaphor of the sphere and metaphors, as the metaphor of the circumference and the metaphor of the circle, has been frequent in the philosophical literature. Apart the oriental tradition, to which we refer at the end of the present article, can already be said from the Pythagorean ones, the sphere was considered to be like the most perfect of the figures; it was proving, since almost inevitably to refer to whenever the image of the plenitude wanted to happen.

Dictionary of philosophy, Volume 2 written by José Ferrater Mora, Josep-Maria Terricabras, 1077 paginates.

we Can realize at philosophical level our this life marked by our environment as our reality, which represents our circumference, where the way that we take in a decision or exposition would be ours radio in our circumference, since everything turns around us.

we can define The circumference, inside a geometric plane, inside this one it exists a point, which moves itself in a constant distance of a fixed point inside this plano.la constant distance is the radio, a very important fact places a condition of an equation of the second grade, for having two variables, own of this one to complement if his radio and his center is known.

In the height of physics, we have the representation of a circumference, to understand better the visualization of the movement of the particle, loaded in a magnetic uniform field, in such a way that there goes off a particle loaded positively with a represented speed of way vectorial, v this despliega in a perpendicular form for the magnetic field, waving other particles doing a force in F with regard to v, thanks to it it happens that it changes the direction into the points: M, N, P, Q, staying the module in v constant. In case of the radio in R, of sample a movement inside this circumference with the opposite sense of the needles of the clock.

Next continuing in the field of the physics we have, since the change is demonstrated it continued of direction of the vector of a tangential way that causing a centripetal acceleration of movement, the above mentioned movement it is perpendicular at the tangential speed and of the same this form it goes towards the center, in which the mobile is described, it is for it as which 0 has an origin. Every increase of every vector, it is represented of way hodógrafa of this movement, because when we speak about this movement we allude in the one that turns, in an angle of 360 ° with angular constant speed.

We have the case when when the centripetal speed ac has the same direction of the distinguishing vector of the increase, consequently it is at all times perpendicular at the tangential speed. Since one concludes that it has the direction of his radio, which in turn goes in the center of the circumference in which the mobile is described.

We have the following contribution on the subject of astrology where:

planetary Tránsitos It is called an astronomical transit, to the step of a celestial body ahead of other of major relative size. If the size relative they are similar, of that time the transit is named an eclipse, from the ground we can observe transit between a planet and a star, transit between satellite and planets.

Is for it that there is better the application of the circumference and ellipses, to determine it distances them and his orbit, since in the situation of the Tuesday orbit it was lengthened and of the ground in the raised lines it joins with the Sun, where stable the consideration that a planet covers equal areas in the same time, that owes for the gravitational fields.

Another important application of the circumference, is that it served as base to explain the law of Kepler, in which they supported in the application of the circumference of an empirical way to the science. In his first law, it raises us that the these planets slide on the elliptical one under a circular geometry.

In the second law one raises that the planets move in a line, which is faced towards the Sun, under the same interval of time.

In the third law, in this case it shows us as the squares of the periods of revolucionen T it is proportional to the bucket for the planets, in his distance average faced towards the sun, of such a way of explaining the distance I mediate to the Sun and the period of revolution of the planets of our solar system.

Observe the diversity of the application of the circumference from our life up to the scientific knowledge, where the natural phenomena and of the cosmos judgment was established to base the study of the astronomy, of the movement in the field of the geometry, thanks to it theories were established and models of such a magnitude initiated of a circumference up to perfecting one geoheliocéntrico.
