Ptolemy's Almagest is one of the most influential scientific works in history. A masterpiece of technical exposition, it was the basic textbook of astronomy for more than a thousand years, and still is the main source for our knowledge of ancient astronomy. This translation, based on the standard Greek text of Heiberg, makes the work accessible to English readers in an intelligible and reliable form. It contains numerous corrections derived from medieval Arabic translations and extensive footnotes that take account of the great progress in understanding the work made in this century, due to the discovery of Babylonian records and other researches. It is designed to stand by itself as an interpretation of the original, but it will also be useful as an aid to reading the Greek text.
Claudius Ptolemy, one of the greatest scientists of all time, probably lived in Alexandria in the second century A.D. His writings dominated astronomy and cosmology in medieval times. The replacement of his Earth-centered cosmology by the Sun-centered cosmology of Copernicus is the most celebrated event in the history of science. Yet, although there has been much scholarly discussion of the mathematical aspects of Ptolemy's astronomy, little attention has been paid to the philosophical, and particularly the ethical, ideas which animate the astronomy. Ptolemy's Universe is the first modern examination of Ptolemy's thought as a whole, and its place in Greek intellectual culture.
The Crime of Claudius Ptolemy by Robert R. Newton Pdf
In Newton's view, Ptolemy was "the most successful fraud in the history of science". Newton shows that Ptolemy predominantly obtained the astronomical results described in his work The Almagest by computation, and not by the direct observations that Ptolemy described.
Dialogue Concerning the Two Chief World Systems by Galileo Pdf
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.
The Book of Astronomy in Antiquity (Concise Edition) by Ptolemy Pdf
Ptolemy's work in ancient times laid the foundations for our modern understanding of the universe. Now in a digestible, pocket format for the modern reader. Ptolemy’s great astronomical work, which we know as The Almagest, brought together the ideas of Greek Antiquity, based on Aristotle some 400 years earlier, that the sun and planets revolved around the earth. This geocentric view which was inherited by Byzantine and Islamic scholars until Copernicus’ observations 1400 years later, placed the sun at the focal point of the solar system. For centuries Ptolemy’s methods were sufficient to predict solar and lunar eclipses and his work was translated into Latin in the 12th century, spreading its use across western Europe. This new, accessible edition brings the learning of the past to readers of today. The FLAME TREE Foundations series features core publications which together have shaped the cultural landscape of the modern world, with cutting-edge research distilled into pocket guides designed to be both accessible and informative.
The Wraparound Universe by Jean-Pierre Luminet Pdf
What shape is the universe? Is it curved and closed in on itself? Is it expanding? Where is it headed? Could space be wrapped around itself, such that it produces ghost images of faraway galaxies? Such are the questions posed by Jean-Pierre Luminet in The Wraparound Universe, which he then addresses in clear and accessible language. An expert in black holes and the big bang, he leads us on a voyage through the surprising byways of space-time, where possible topologies of the universe, explorations of the infinite, and cosmic mirages combine their mysterious traits and unlock the imagination. The Wraparound Universe is a general-audience book about the overall topology or shape of the universe. The central question addressed is whether it is possible that the universe is wrapped around in an interesting way, and what impact this would have on astronomical observations and our understanding of cosmology. Along the way many of the general features and much of the history of the modern picture of cosmology are discussed.
An account of the Copernican Revolution, focusing on the significance of the plurality of the revolution which encompassed not only mathematical astronomy, but also conceptual changes in cosmology, physics, philosophy, and religion.
Ptolemy's Planetary Theory by Elizabeth Anne Hamm Pdf
This study comprises a translation and commentary of Book I of the Planetary Hypotheseses by the second century A.D. Greco-Roman astronomer, Claudius Ptolemy. It closely examines the Planetary Hypotheses on its own and in relation to Ptolemy's other writings. Where necessary I rely on astronomical, philosophical, and technological works by other writers in order to better situate Ptolemy's ideas into the context of Greco-Roman science.The dissertation is organized into three sections. Section I consists of an extended introduction to the Planetary Hypotheses. I offer a synopsis of the Planetary Hypotheses and a history of the text in Sections I.1 and I.2. Section I.3 consists of a brief introduction to notation and sexagesimal numbers while Section I.4 analyzes the aim and function of Ptolemy's planetary models.Section II is a translation of the existing Greek text of the Planetary Hypotheses, namely Book I Part A, and a precis of Book I, Part B. The translation is made from J.L. Heiberg's edited Greek text and the precis relies on the English translation by Bernard Goldstein, the French translation by Regis Morelon, and the Arabic Manuscripts found in the British Library (Arabic-A) and the Library at the University of Leiden (Arabic-B). The footnotes include variant readings from the different Greek and Arabic Manuscripts. A list of all existing manuscripts of the Planetary Hypotheses can be found in Section I.2While I focus on the changes that Ptolemy made to the models in the Planetary Hypotheses from his theories in the Canobic Inscription, Handy Tables, and the Almagest, this work aims to explore the motivations behind these changes. Additionally, I contextualize the Planetary Hypotheses within Greco-Roman and Islamic astronomy and technology. What emerges from this dissertation is a consideration of Ptolemy's ideas about the practice of science and an analysis of how he modeled astronomical observations.Section III is a commentary of the entirety of Book I (Parts A and B). This section is arranged so that it loosely follows the order of topics found in the Planetary Hypotheses Section III.1 examines the Planetary Hypotheses in terms of instrument-making. Section III.2 discusses the geometric models that Ptolemy presents along with a discussion of the changes that he makes. I give an overview of the period relations and mean motions presented in the Planetary Hypotheses in Section III.3 and III.4 and the new frame of reference in Section III.5. Section III.6 briefly examines Book II of the Planetary Hypotheses and Section III.7 addresses the relationship of Book I and Book II and contextualizes this work in the history of Greco-Roman science. Finally, Section III.8 examines the role the Planetary Hypotheses played in developments within Medieval Islamic astronomy.
A stimulating intellectual history of Ptolemy's philosophy and his conception of a world in which mathematics reigns supreme The Greco-Roman mathematician Claudius Ptolemy is one of the most significant figures in the history of science. He is remembered today for his astronomy, but his philosophy is almost entirely lost to history. This groundbreaking book is the first to reconstruct Ptolemy’s general philosophical system—including his metaphysics, epistemology, and ethics—and to explore its relationship to astronomy, harmonics, element theory, astrology, cosmology, psychology, and theology. In this stimulating intellectual history, Jacqueline Feke uncovers references to a complex and sophisticated philosophical agenda scattered among Ptolemy’s technical studies in the physical and mathematical sciences. She shows how he developed a philosophy that was radical and even subversive, appropriating ideas and turning them against the very philosophers from whom he drew influence. Feke reveals how Ptolemy’s unique system is at once a critique of prevailing philosophical trends and a conception of the world in which mathematics reigns supreme. A compelling work of scholarship, Ptolemy’s Philosophy demonstrates how Ptolemy situated mathematics at the very foundation of all philosophy—theoretical and practical—and advanced the mathematical way of life as the true path to human perfection.
On the Heavens Aristotle - On the Heavens is Aristotle's chief cosmological treatise: written in 350 BC it contains his astronomical theory and his ideas on the concrete workings of the terrestrial world. This work is significant as one of the defining pillars of the Aristotelian worldview, a school of philosophy that dominated intellectual thinking for almost two millennia. Similarly, this work and others by Aristotle were important seminal works by which much of scholasticism was derived.
Matter and Form explores the relationship that has long existed between natural science and political philosophy. Plato's Socrates articulates the Ideas or Forms as an account of the ultimate source of causality in the cosmos. Aristotle's natural philosophy had a significant impact on his political philosophy: he argues that humans are by nature political animals, having their natural end in the city whose regime is hierarchically structured based on differences in moral and intellectual capacity. Medieval theorists attempt to synthesize classical natural and political philosophy with the revealed truths of scripture; they argue that divine reason structures an ordered universe, the awareness of which allows for psychic and political harmony among human beings. Enlightenment thinkers challenge the natural philosophy of classical and medieval philosophers, ushering in a more liberal political order. For example, for Hobbes, there is no rest in nature as there are no Aristotelian forms or natural places that govern matter. Hobbes applies his mechanistic understanding of material nature to his understanding of human nature: individuals are by nature locked in an endless pursuit of power until death. However, from this mechanistic understanding of humanity's natural condition, Hobbes develops a social contract theory in which civil and political society is constituted from consent. Later thinkers, such as Locke and Rousseau, modify this Hobbesian premise in their pursuit of the protection of rights and a free society. Nevertheless, materialist conceptions of the cosmos have not always given rise to liberal democratic philosophies. Historicist influence on scientific inquiry in the nineteenth century is connected to Darwin's theory of evolution; Darwin reasoned that over time the process of natural selection produces ever newer and more highly adapted species. Reflecting a form of social Darwinism, Nietzsche envisions an aristocratic order that draws its inspiration from art rather than the rationalism embodied in the history of natural and political philosophy. Matter and Form's interdisciplinary approach, by international scholars in philosophy and political science, suits it for researchers, teachers and students of these fields.
On the Revolutions of the Heavenly Spheres (Concise Edition) by Copernicus,Marika Taylor Pdf
Controversial at the time, Copernicus's discoveries led to the scientific revolution, and a greater understanding of our place in the universe. An accessible, abridged edition with a new introduction. Renaissance Natural philosopher Nicolaus Copernicus's pioneering discovery of the heliocentric nature of the solar system is one of the few identifiable moments in history that define the understanding of the nature of all things. His great work was the consequence of long observation and resulted in the first stage of the Scientific Revolution by correctly positing that the earth and other planets of the solar system revolved around the sun. Not only did this promote further study to understand the place of humanity in the world and the universe, it questioned the authority of the organised Christian Church in the West to be the keeper of fundamental truths. Ultimately this would lead to the Enlightenment, and the separation of religion, government and science.
