New to Penguin Classics, the astonishing story of the Copernican Revolution, told through the words of the ground-breaking scientists who brought it about In 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

Galileo’s Dialogue Concerning the Two Chief World Systems, published in Florence in 1632, was the most proximate cause of his being brought to trial before the Inquisition. Using the dialogue form, a genre common in classical philosophical works, Galileo masterfully demonstrates the truth of the Copernican system over the Ptolemaic one, proving, for the first time, that the earth revolves around the sun. Its influence is incalculable. The Dialogue is not only one of the most important scientific treatises ever written, but a work of supreme clarity and accessibility, remaining as readable now as when it was first published. This edition uses the definitive text established by the University of California Press, in Stillman Drake’s translation, and includes a Foreword by Albert Einstein and a new Introduction by J. L. Heilbron.

Galileo's 1632 book, "Dialogue on the Two Chief World Systems, Ptolemaic and Copernican," comes alive for twentieth-century readers thanks to Maurice Finocchiaro's brilliant new translation and presentation. Condemned by the Inquisition for its heretical proposition that the earth revolves around the sun, Galileo's masterpiece takes the form of a debate, divided into four "days," among three highly articulate gentlemen.
Finocchiaro sets the stage with his introduction, which not only provides the human and historical framework for the "Dialogue" but also admits the reader gracefully into the basic non-Copernican understanding of the universe that would have been shared by Galileo's original audience. The translation of the "Dialogue" is abridged in order to highlight its essential content, and Finocchiaro gives titles to the various parts of the debate as a guide to the principal topics. By explicating his own critical reading of this text that is itself an exercise in critical reasoning on a gripping real-life controversy, he illuminates those universal, perennial activities of the human mind that make Galileo's book a living document. This is a concrete, hands-on introduction to critical thinking. The translation has been made from the Italian text provided in volume 7 of the Critical National Edition of Galileo's complete works edited by Antonio Favaro. The translator has also consulted the 1632 edition, as well as the other previous English translations, including California's 1967 version.
"Galileo on the World Systems" is a remarkably nuanced interpretation of a classic work and will give readers the tools to understand and evaluate for themselves one of the most influential scientific books in Western civilization.

'The truth which we arrive at by means of mathematical proofs is the same truth that is known to divine wisdom.' Galileo's Dialogue on the Two Greatest World Systems, the most brilliant and persuasive defence of the Copernican theory that the Earth goes around the Sun to have been written in the seventeenth century, is one of the foundation texts of modern science. This new translation renders Galileo's lively Italian prose in clear modern English, making the whole of Galileo's text readily accessible to modern readers, while William Shea's introduction and notes give a clear overview of Galileo's career and draw on the most recent scholarship to explain the scientific and philosophical background to the text. This volume provides everything necessary for an informed reading of Galileo's masterpiece.

Galileo Galilei's Sidereus Nuncius is arguably the most dramatic scientific book ever published. It announced new and unexpected phenomena in the heavens, "unheard of through the ages," revealed by a mysterious new instrument. Galileo had ingeniously improved the rudimentary "spyglasses" that appeared in Europe in 1608, and in the autumn of 1609 he pointed his new instrument at the sky, revealing astonishing sights: mountains on the moon, fixed stars invisible to the naked eye, individual stars in the Milky Way, and four moons around the planet Jupiter. These discoveries changed the terms of the debate between geocentric and heliocentric cosmology and helped ensure the eventual acceptance of the Copernican planetary system. Albert Van Helden's beautifully rendered and eminently readable translation is based on the Venice 1610 edition's original Latin text. An introduction, conclusion, and copious notes place the book in its historical and intellectual context, and a new preface, written by Van Helden, highlights recent discoveries in the field, including the detection of a forged copy of Sidereus Nuncius, and new understandings about the political complexities of Galileo's work.
