Johannes Kepler

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

Johannes Kepler (Weil der Stadt, 1571-Regensburg, 1630) is the famous astronomer and mathematician who discovered the three planetary laws named after him. In 1615 he published the Nova stereometria doliorum vinariorum // New solid geometry of wine barrels, his most important mathematical monograph. It made him a precursor of infinitesimal mathematics. He himself told the reader in the dedication to his two patrons that his second marriage caused him to write this mathematical treatise. When he stocked up with wine barrels in his capacity as head of a new family he was astonished at the way in which the seller used the gauging rod. The man explored all wine barrels with one and the same rod indifferently without paying heed to the shape, and without ratiocination or calculation. Hence Kepler felt obliged to try to lay down, according to geometrical laws, a new foundation for the mathematical certainty of this measurement and to bring to light its fundamentals, if there should be any. To that end he began with a new interpretation of Archimedes's results in plane and solid geometry that was based on indivisibles considered as infinitely small quantities. He could not know that his Greek predecessor had used the same method in his letter to Eratosthenes, known as Approach related to mechanical theorems, rediscovered by Johan L. Heiberg in 1906. Yet, Kepler surpassed the results of his model by his own results. He investigated the volumes of surfaces of rotation like the volumes of apples, lemons, and spindles, that is, he investigated the solid geometry of figures that are closest to conoids and spheroids. But Kepler's treatise is by no means restricted to its role in the prehistory of the calculus. The second part is full of non-trivial, new results concerning the special relations between cylinders and so-called conjugate conical frustums. He demonstrated that the Austrian barrel has the largest volume among all barrels with the same gauging length. Thus the third part explains the use of the gauging rod. The volume presents, along with the original Latin text, the first complete translation of Kepler's monograph into any modern European language, in this case into English. The comprehensive introduction includes a survey of Kepler's life and works and explains the main ideas, methods, and results of this mathematical masterpiece.

Somnium is a Latin word for Dream. This novel was written by Johannes Kepler in 1608, in a time when a trip to the ethereal regions of the moon would be possible only with the assistance of supernatural forces. Historians consider this lunar exploration a remarkable and revolutionary text, and one of the most provocative and innovative of Kepler's works. Great authors/scientists such as Isaac Asimov and Carl Sagan suggested it as the first science fiction story. If it is not, we can at least consider it as the first serious scientific work about lunar astronomy.

Second edition, completely revised, of the only English translation of Kepler's 1609 masterpiece. A work of astonishing originality, Astronomia Nova stands, with Copernicus's De Revolutionibus and Newton's Principia as one of the founding texts of the scientific revolution. Kepler revolutionized astronomy by insisting that it be based upon physics rather than ideal geometrical models.

According to Carl Sagan and Isaac Asimov, Kepler s "Somnium" ("The Dream"), written around 1611, should be considered the first science-fiction novel ever. The eminent astronomer Johannes Kepler imagines a trip to the moon and speculates about its inhabitants and astronomy.

Kepler's essay, On the Six-Cornered Snowflake, provides the first published evidence of the ideas of regular arrangements and close-packing which have proved fundamental to crystallography. In it, Kepler ponders on the problem of why snowflakes are hexagonal, two centuries before the first successful steps were taken towards its solution. The purpose of this volume is to display the historical, literary, scientific, and philosophical treasures of Kepler's essay. The book includes the modernized text of the 1611 Latin edition, with an English translation by Colin Hardie on the opposite pages. The text is accompanied by an introduction giving details of the history of the work, and two essays; Professor B. J. Mason's discussion of the scientific meaning and validity of Kepler's arguments and their relation to the history of crystallography and of space filling, and L. L. Whyte's examination of Kepler's facultas formatrix in relation to the history of philosophical and scientific ideas on the genesis of forms.
