Al poco tiempo de llegar Graz como joven profesor de matemáticas y astronomía, Kepler se encontró sin alumnos y hubo de ganarse la vida dando clases sobre Virgilio y retórica, y su pasión por la astronomía se abrió paso siguiendo dos vías: la primera consistió en componer un horóscopo para 1595 que anunciaban fríos desusados, levantamientos campesinos y avances del turco; así aconteció. La segunda fue para dar un explicación y superación de Copérnico, quien había ofrecido una explicación verdadera de la estructura y orden del cosmos sin llegar a saber por qué eran así las cosas. EL SECRETO DEL UNIVERSO es el primer tratado copernicano de la historia. Sin embargo supera a Copérnico al explicar tres cosas: por qué hay precisamente seis planetas, ni uno más ni uno menos; por qué están a las distancias del sol que se encuentran, y por qué se mueven con la velocidad que lo hacen. Por primera vez desde los tiempos de Aristóteles, JOHANNES KEPLER aúna las matemáticas y la física para desvelar

Johannes Kepler wrote "Astronomia Nova" (1609) in a single minded drive to sweep away the ancient and medieval clutter of spheres and orbs and to establish a new truth in astronomy, based on physical causality. This title includes Kepler's introduction as well as a selection of chapters that develop the physics of planetary motion.

"The Optics" was a product of Kepler's most creative period. It began as an attempt to give astronomical optics a solid foundation, but soon transcended this narrow goal to become a complete reconstruction of the theory of light, the physiology of vision, and the mathematics of refraction. The result is a work of extraordinary breadth whose significance transcends most categories into which it might be placed. It gives us precious insight into Kepler's thought during this crucial period, an insight all the more valuable in that most of his working papers from that time have been lost. Second, it is the culmination of a long and rich tradition in the science of optics, in distinct contrast with the new optical thought represented by Descartes. And third, it presents discoveries in the physiology of vision, photometry, and the geometry of conic sections which have become part of our intellectual heritage. Especially notable are Kepler's discovery of the inverted retinal image, his theoretical grounding of the inverse-square photometric law, and his insights into the relations between the various conic sections.

New to Penguin Classics, the astonishing story of the Copernican Revolution, told through the words of the ground-breaking scientists who brought it aboutIn the late fifteenth century, it was believed that the earth stood motionless at the centre of a small, ordered cosmos. Just over two centuries later, everything had changed. Not only was the sun the centre of creation, but the entire practice of science had been revolutionised. This is the story of that astonishing transformation, told through the words of the astronomers and mathematicians at its heart. Bringing together excerpts from the works and letters of Copernicus, Galileo, Kepler, Descartes, Newton and others for the first time, The Dawn of Modern Cosmology is the definitive record of one of the great turning points in human history.Edited with Translations, Notes and an Introduction by Aviva Rothman
