Dioptrice, Somnium manuscript and other
After the end of Kepler’s Astronomia Nova was the work of Rudolf and put an end to the list based on a complete ephemeris (that is written in the heavens US) formulated. None, however, did not end in the near future. During the collaboration with Italian astronomer Giovanni Antonio majini-tried failed. Some of his other works were the chronology, the events of Jesus’ life, especially formulated and astrology. <span title=”তিনি জ্যোতিষ শাস্ত্রের মাধ্যমে কোন নাটকীয় বিপর্যয়ের ভবিষ্যদ্বাণী করার সমালোচনা করেছেন।
“>He also criticized the dramatic predictions of catastrophe through astrology.
His onetime classmate Rogelio helisaiyusa more on astrology would even Copernicus and Kepler did not like thinking. They consistently attacked each other in several writings. The doctor Philip phejeliyusa astrology books written by the cancellation of a major target of criticism was the work rojelinera. On the one hand, and the excesses of astrology too jealous of it as a reaction between the barjana Kepler tertiyusa interabheniyensa (third party intervention) wrote a book called phejeliyusera General Rogelio and sent to the sponsor. Memorandum of Understanding between the two sides of intellectuals, but this book was written to Kepler’s actual views about astrology is known. The interaction between the planet and the human soul in the manner he has appeared in a substitution. Astrologers traditional rules and methods compared with the smelly stool seekers While hen, but there is a conscientious scientific astrologer grain to be found.
1610, the first of its powerful new telescope Galileo discovered four satellites orbiting Jupiter. Nunakiyusa as Sidereus (Starry Messenger) reports this discovery through the book you want to know the opinion of Kepler, Galileo, increases the credibility of his observations. Kepler enthusiastically opinion through a letter published in the name of the letter diseratasio Kum nunakio Sidereo (Conversation with the Starry Messenger). He endorsed Galileo’s observations and astronomy, optics, cosmology and astronomical telescope by Galileo to the discovery of the meaning and effectiveness of technology discussed. At the end of the year, with the publication of narasio de jobhisa satelitibusa moon seen through his telescope described. This is confirmed by observations of Galileo. <span title=”কিন্তু গালিলেও কখনও আস্ত্রোনোমিয়া নোভার প্রতিক্রিয়া (যদি আদৌ থেকে থাকে) প্রকাশ করেননি বলে কেপলার বেশ হতাশই হয়েছিলেন।
“>But Galileo Astronomia Nova response (if any) Kepler’s disappointment, never published. 
Colognes, after receiving news of Galileo’s telescopic discoveries, Kepler telescope optics using a telescope borrowed from Duke Ernest of theoretical and experimental research began.  As a result, in 1610 a new manuscript, which was finished in 1611 Dioptrice (Diopotrice) is published . It was described in the bi-convex convergent interests and divergent bi-concave lens, a combination of the theoretical basis and the emergence of the Galilean telescope, resources and reflection asada, upright vs. inverted images, and impact of focal length on magnification and reduction. He also assumed a new form in which the astronomical or Keplerian telescope telescope. Like Galileo’s combination of convex and concave lenses durabine the two convex lenses are used instead of magnification increases.
Around 1611, Kepler circulated a manuscript after the death of his Somnium (Somnium, dreams) were published. Any other purposes in writing this book was a sort of planetary astronomy, which describes the subject. He originally wanted to highlight the acceptance of the theory that the Earth is considered the center of the universe. After the manuscript disappeared in the hands of a few people around. A phobia moon mission craft the story described in the book, the manuscript is somewhat symbolic, some manifestation of thought in his autobiography, and some of interplanetary travel. Carl Sagan described as one of the first science fiction.  After several years manuscript aired witchcraft abhiyago probably due to a distorted version of his mother was arrested. The story of the mother of the narrator consults a demon to learn the means of space can be seen. After the release of Kepler’s mother with the story of the original story, which was 223 more than a footnote to grow. Used in a variety of symbolic meaning of the story, hidden in various scientific ideas and discussed the geology of the moon comes up.
Mathematics and physics
New Year’s gift to his friend and one-time patron Baron von bhakhenapheldera bhakhara for that year, he Strena Seu de Nive Sexangula (New Year’s Gift of Hexagonal Snow) wrote a short pamphlet entitled. This hexagonal symmetry of snowflakes, he described for the first time, which resulted in an atomistic symmetry explains. The most effective way for packing spheres about the Kepler conjecture that comes out is called a hypothesis.   Kepler was one of the pioneers of the mathematical applications aniyanera.
Personal and political troubles
In 1611 in Prague, in the guise of religious-political tension. Emperor Rudolf and his brother Matthias, due to deteriorating physical condition, he was forced to retire from his position as King of Bohemia. Both Rudolf and Matthias Kepler’s astrological advice. Taking advantage of the advice he aposamulaka tried to improve the situation, very little comment about the stars, so that a sudden kings do not take action. But it was not realized that the rest of the court of Matthias Kepler’s future was neise year, Barbara Kepler contracted Hungarian spotted fever, then began having seizures, symptoms of the disease. Barbara was recovering, his three children are sick with smallpox, 6-year-old Friedrich died. After the death of his son in astronomy or mathematics in Padua and bhyuatemabergera office sent letters to patrons. Bhyuatemabergera tyubinena Calvinist heretics, and the University of Augsburg Confession (Lutheran Church of the Confession of Faith) and the Formula of Concord (Lutheran Church of Faith Promise) due to violation of Kepler’s did not agree. In 1610, Galileo went to the University of Padua in the gaps caused invites him to meet the university authorities. But Kepler was in Linz, Austria, in German, on the ground that it is better to be in a position to arrange the district mathematician. However, he came back after a few days due to illness, Barbara, died karenae dates back to Kepler in Linz decided to stay in Prague with a little. Emperor Rudolf II in 1612 until his death, even though there was political instability, religious intolerance, and his wife’s family’s suffering land of his research was accomplished during this time due to the complexity of the legislation. At the time, he did not see the previous research work and with the help of others to create a chronology of ekalogai kronikai busy. Matthias was crowned Holy Roman Emperor, in his previous job after job with full pay was reinstated and allowed him to move to Linz.
