Hvorfor Johannes Kepler har sin egen kategori i denne bloggen
Johannes Kepler drev kanskje på med uvitenskapelig tull som astrologi, men det var fordi det ikke var noe skille mellom vitenskapen astronomi og tullete astrologi på hans tid. Jeg tror Carl Sagan sa det best da ha sa "the first astrophysicist and the last scientific astrologer."
Han trodde på Gud også, men det hindret han aldri fra å studere og prøve å forstå universet i motsetning til svært mange kristne på hans tid (og dessverre mange kristne i dag).
Og selv om han kastet bort store deler av livet sitt på ideen om at Gud er geometri og universet er i perfekt geometri med Gud, så forkastet han dette synet etter som han innså at bevisene ikke passet. Dette gjør han etter min mening til en ekte vitenskapsmann i stedet for en tulling som prøver å gå den andre veien.
Han er mann som har betydd noe godt for menneskeheten og ikke minst vitenskapen.

Kepler's Belief in Astrology by Nick Kollerstrom
Kepler's lifelong attempt to recast astrology within a harmonic-Pythagorean framework has relevance today. The year 1987 saw the first visible supernova since Kepler's star of 1604.[1] At the quatercentenary of his De Stella Nova of 1606 about the new star and his theories of how astrology worked, this seems an appropriate time to re-examine the achievement.
Very few of Kepler's astrological works have been translated into English down the centuries, which has permitted a radically one-sided interpretation of his work to flourish. In recent years, however, modern translations of one of Kepler's seminal works on the theory of how astrology works have appeared,[2] which have been made available for the first time to English readers a perspective on what he really believed. That one of the great creative founders of modern science struggled for decades to relate together astronomy and astrology is a matter of no small importance.

Dessverre var Kepler en astrolog i tillegg til å være astronom, men i gjengjeld var har han hatt mye å si for grunnlaget av moderne vitenskap til tross av dette astrologitullet.

Kepler's Somnium: Science Fiction and the Renaissance Scientist
In 1634, four years after his death, the most provocative and innovative of Johannes Kepler’s works was published by his son Ludwig Kepler, then a candidate for the doctorate in medicine. In one form or another, the manuscript had been the elder Kepler’s constant companion since his student days at Tübingen University where his introduction to the heliocentric system, revived from the ancient Greeks by the Polish astronomer Nicholas Copernicus, had prompted Kepler to devote one of his required dissertations to the question: "How would the phenomena occurring in the heavens appear to an observer stationed on the moon?" The theses propounded by Kepler at Tübingen in 1593 contained, in the words of his German biographer Max Caspar, "the first germ of a work which we shall come to know as the last of the books he published," the Somnium or Dream.1
It had been Kepler’s intent to personally supervise the publication of his manuscript and, at the time of his sudden death in 1630, six pages of the document were in type. Jacob Bartsch, Kepler’s son-in-law, undertook the task of completing publication but he, too, died suddenly before it was finished. The project might well have been abandoned at this point had not Kepler left his widow in dire financial straits. In an attempt to assist his mother during this economic crisis, son Ludwig brought the thin volume to press in 1634. In accordance with the medieval-classical tradition—broken only by Kepler’s contemporary Galileo, who occasionally published in the vernacular—the original edition was in Latin. Over two centuries passed before a second Latin edition was published in 1870 in volume eight of the Opera Omnia, a collection of Kepler’s works edited by Christian Frisch. This was followed in 1898 by a rather poor and quite obscure German paraphrase under the title Kepler’s Traum Von Mond by Ludwig Gunther. Except for these two limited editions and a few surviving copies of the original printing, a seminal work in science fiction remained a literary curiosity for over three centuries, read only by those few authors with a strong interest in the new genre and possessed of the classical background required to read the work in its original Latin.
