Zurück zu: Astronomisches Zentrum Magdeburg Einige Fotos Astronomische Gesellschaft Magdeburg e.V. WIR SIND eine Gruppe von zur Zeit 25 Amateurastronomen im Alter von 18 bis 62 Jahren. Mehrere Sternfreunde betreiben das Hobby schon seit mehr als 30 Jahren. Ein Grund von vielen, warum so mancher sein ganzes Leben dem Hobby Astronomie treu bleibt, ist die einmalige Möglichkeit, moderne optische und elektronische Technik mit dem reinen Naturerlebnis zu verbinden. Gegründet wurde unser Verein 1992. Er ist aus zwei astronomischen Fachgruppen des Kulturbundes der ehemaligen DDR hervorgegangen.
UNSERE ZIELE:
  • amateurastronomische Betätigung auf vielen Gebieten der Astronomie Erfahrungsaustausch auf amateurastronomischem Gebiet Verbreitung astronomischen Wissens in der Öffentlichkeit Kontakt zu anderen astronomischen Vereinen Ausbau, Pflege und Erhalt der Volkssternwarte Unterstützung der Schulastronomie
WAS BIETET UNSER VEREIN ?
  • Eigene Beobachtung interessanter Himmelserscheinungen an der Volkssternwarte "Johannes Kepler" Vermittlung astronomischen Wissens für Anfänger und Fortgeschrittene Öffentliche Beobachtungen für die Bevölkerung Exkursionen zu interessanten astronomischen Einrichtungen (Sternwarten, Planetarien, Ausstellungen u.a.)

Kepler and the First Law of Planetary Motion
Jenny Hwang
Johannes Kepler was an astronomer, mathematician, theologian and philosopher. His many achievements are commendable but it is one particular triumph which is familiar to many. That is the discovery of Kepler's Laws of Planetary Motion. I will concentrate on his first law: the orbits of the planets are ellipses with the sun at one focus. During his stay at Tübingen, Kepler was especially influenced by his professor of astronomy, Michael Mästlin. Mästlin was a quiet proponent of Copernican astronomy, which supports the idea of a heliocentric (sun-centered) universe. His thorough knowledge of the ideas of Copernicus sparked Kepler's interest in astronomy and created another Copernican advocate. Ironically, Kepler was a reluctant astronomer. Of his interest in the subject, Kepler states, "these were prescribed studies and nothing indicated to me a particular bent for astronomy." Nevertheless, he was a "straight A student" and when he went to renew his scholarship at Tübingen, the senate spoke of Kepler as having "such a superior and magnificent mind that something special may be expected of him." [2] Just after a year of residency at Graz, Kepler published his first work

Johannes Kepler, berühmt als Astronom und Mathematiker, war von Haus aus Theologe; seine Interessen umfaßten aber auch Philosophie, Geschichte, Physik, Metereologie und Astrologie. Auf der Suche nach den Gesetzen kosmischer Harmonie fand er, mit der Hilfe der Beobachtungen Tycho Brahes, drei Planetengesetze, die seinen Namen tragen. Seiner Zeit voraus, setzte er das heliozentrische Weltbild des Kopernikus durch und erkannte die wahren Dimensionen des Sonnensystems, blieb jedoch befangen in der Vorstellung eines endlichen, von Gott geschaffenen Kosmos.

I. Vita e opere
Giovanni Keplero è considerato uno dei più grandi astronomi di tutti i tempi. I trattati di meccanica celeste ricordano le sue tre leggi del moto dei pianeti. Non meno importanti sono i suoi contributi nel campo dell’ottica. È significativo che la sua opera principale, davvero rivoluzionaria, porti il titolo Astronomia Nova , consapevole, com’egli era, di avere con essa profondamente cambiato l’astronomia tradizionale. Dobbiamo infatti a Keplero il merito di aver eliminato una volta per tutte il ricorso a deferenti ed epicicli nell’interpretazione dei moti planetari, ed il superamento del principio assiomatico che tutti i movimenti celesti dovevano essere circolari e procedere con velocità uniforme, principio che aveva dominato tutta l’astronomia antica e medievale e che risultava ancora tanto caro a Copernico. Deciso promotore dell’eliocentrismo sin dalla sua gioventù, Keplero non ebbe nella difesa del copernicanesimo lo stesso ruolo di protagonista del suo contemporaneo

    Johannes Kepler's Polyhedra
    Johannes Kepler (1571-1630), best known for his three laws of planetary motion, was one of the most outstanding mathematicians of his day. In addition to his astronomical accomplishments, he systematized and extended all that was known about polyhedra in his time. While previous artist/geometers discovered particular polyhedra, he took a more mathematical approach: he defined classes of polyhedra, discovered the members of the class, and proved that his set was complete. For example, Kepler discovered the infinite class of antiprisms Kepler's logical approach to polyhedra does not mean that he was free of the mysticism of the day. The following illustration, from his 1619 book, Harmonice Mundi , graphically shows the Platonic associations of the regular solids with the classical elements: The tetrahedron corresponds to fire, the octahedron to air, the cube to earth, the icosahedron to water, and the dodecahedron to the cosmos or ether: The lower-left portion of the above figure illustrates Kepler's two star polyhedra, the small stellated dodecahedron and the great stellated dodecahedron . Although earlier illustrations of these solids exist, Kepler was the first to recognize them as meeting the definition of regular polyhedra, but with nonconvex

  • Kepler's Laws of Planetary Motion
    • Uniform Circular Motion
    • Kepler's First Law: All planets move about the sun in an elliptical orbit with the sun at one foci. In an elliptical orbit the distance between the planet and the sun is continuously varying:
    • Keplers Second Law: Equal Areas in Equal Times Keplers Third Law: The Harmonic law which is mathematically stated as follows: In the above P is the orbital period measured in years and A is the semi-major axis measured in units of AU (the distance from the earth to the Sun). This empirical expression sets the scale of the solar system. For instance, if I observe an object to have an orbital period of 8 years then I know that it must have a semi-major axis of 4 AU, by the above expression. This solution is shown below:
    Ptolemy's Desperate Attempt
      The discovery of retrograde motion in the orbit of mars was a serious challenge to the standard geocentric cosmology which demanded that all the planets orbit the earth in the same direction. While retrograde motion has a natural explanation in a heliocentric cosmology, Ptolmey came up with an elaborate machine to both explain the observed retrograde motion and to keep the earth at the center of the Universe. This mechanism is shown in the movie below - thank goodness the real Universe doesn't work like this!:
