Joseph Hemmes, CAS Student Advising Center Syllabus PHYSICS-UA 14 Spring 2017 Professor Peter Nemethy PHYSICS and ASTRONOMY in the RENAISSANCE Course Description. In addition to the magnificent flowering of the arts in the Renaissance, the Renaissance period was also one of extraordinary advance in science, in particular in astronomy and physics. The course will examine this advance, emanating from the scientific developments in the European and Italian centers of learning during the Renaissance and at the start of the Age of Enlightenment, in the light of prior wisdom. The topics will center on the 'Copernican Revolution' of Nicolaus Copernicus, Johannes Kepler, and Galileo Galilei that was the beginning of observational science and astronomy. The course is a combined science and science-history course, open to all students, including non-science majors, with no prerequisites. Course Content. CLASSICAL GREEK ANTECEDENTS Alternative theories of the Universe in ancient Greece: Heraclides Philolaus, Heraclides Ponticus, Aristarchus of Samos. Physics according to Aristotle. Ptolemy’s “definitive” Treatise on Astronomy: the earth-centered Universe, accepted for 1200 years afterwards. Its introduction into European thought by way of the Islamic-Arabic translation, the “Almagest”. THE COPERNICAN REVOLUTION (1473 – 1642): 170 decisive years. The development of observational science in the period of the Renaissance. We will consider the new astronomy and physics, as well the trends of acceptance and especially of resistance in the Italian dominions and in the papal court. This is the central content of the course. Nicolaus Copernicus initiates modern astronomy with his Heliocentric model of the universe with the earth orbiting around the sun. His contributions and his visits to Bologna and Rome. Defensive corrections for the Ptolemeic picture: epicycles upon epicycles. Results from Tycho Brahe, a superb astronomical observer. Johannes Kepler’s “Astronomia Nova” with his laws of elliptical planetary motion around our Sun. Interlude: Leonardo DaVinci, inventor, scientist, engineer. The great and versatile Galileo Galilei, physicist, mathematician, astronomer, philosopher. Galileo the inventor: a practical astronomical telescope. Galileo the physicist: results on the pendulum and on falling objects. Galileo’s patrons in the Italian dominions and in the papal court. Observational astronomy, with Galileo’s telescope, of the moons of Jupiter and the phases of Venus rules out the earth at the world’s center. Galileo’s 1632 “Dialogue Concerning the Two Chief World Systems” conclusively establishes the Heliocentric picture. Galileo and the Inquisition: his trial, his recantation, and a full 300 years to acceptance by the Vatican. Giordano Bruno, the first cosmologist of an infinite Universe, and his fate, worse than Galileo’s. CULMINATION and CONCLUSION in the Age of Enlightenment in England. Sir Isaac Newton: Physicist, Mathematician, Astronomer, Natural Philosopher, Theologian, and Alchemist. Born in the year of Galileo’s death. His “Philosphiae Naturalis Principia Mathematica” in 1687. Newton’s Three Laws of Motion. Newton’s Universal Law of Gravitation. Mechanics as a predictive science for cannonballs. planets, and apples. Identical Laws of Mechanics govern Heaven and Earth.

  • Make up Lab: Phases of Venus Introduction Galileo Is Justifiably Famous for Many Discoveries in Both Physics and Astronomy
    PHYS 1401: Descriptive Astronomy Summer 2016 Make Up Lab: Phases of Venus Introduction Galileo is justifiably famous for many discoveries in both physics and astronomy. While he was fascinated by gravity and kinematics, his most valuable discovery is arguably the phases of Venus. By carefully observing and recording the progression of Venus through phases similar to our own moon, he was able to demonstrate the impossibility of the Ptolemy’s increasingly complicated geocentric model. 4. Orient yourself: Toggle on the constellation outlines and labels. Locate one or two constellations whose shapes you know. Are the constellations of 1610 recognizable to you? Face north and locate Polaris. Comment on the location of Polaris compared to its position today. Synodic Period of Venus The synodic period of an object is a measure of its motion with respect to Earth. We are most familiar with this idea as applied to the moon: to measure its synodic period, we count the time between successive full moons (or new moons, or whichever phase you like). As Galileo discovered, we can do precisely the same thing for Venus. 5. Change the date and locate Venus: Advance your date to May 01, 1610. Keep the time set to 00:00:00. Locate Venus, and zoom in to notice its phase. Advance your day until Venus Using the Stellarium program, we can replicate his is fully illuminated (100.0%) and record the date. Use the table observations by placing ourselves in the same time and place below as a model for recording your data. as Galileo himself. 6.

  • NASA and Planetary Exploration
    **EU5 Chap 2(263-300) 2/20/03 1:16 PM Page 263 Chapter Two NASA and Planetary Exploration by Amy Paige Snyder Prelude to NASA’s Planetary Exploration Program Four and a half billion years ago, a rotating cloud of gaseous and dusty material on the fringes of the Milky Way galaxy flattened into a disk, forming a star from the inner- most matter. Collisions among dust particles orbiting the newly-formed star, which humans call the Sun, formed kilometer-sized bodies called planetesimals which in turn aggregated to form the present-day planets.1 On the third planet from the Sun, several billions of years of evolution gave rise to a species of living beings equipped with the intel- lectual capacity to speculate about the nature of the heavens above them. Long before the era of interplanetary travel using robotic spacecraft, Greeks observing the night skies with their eyes alone noticed that five objects above failed to move with the other pinpoints of light, and thus named them planets, for “wan- derers.”2 For the next six thousand years, humans living in regions of the Mediterranean and Europe strove to make sense of the physical characteristics of the enigmatic planets.3 Building on the work of the Babylonians, Chaldeans, and Hellenistic Greeks who had developed mathematical methods to predict planetary motion, Claudius Ptolemy of Alexandria put forth a theory in the second century A.D. that the planets moved in small circles, or epicycles, around a larger circle centered on Earth.4 Only partially explaining the planets’ motions, this theory dominated until Nicolaus Copernicus of present-day Poland became dissatisfied with the inadequacies of epicycle theory in the mid-sixteenth century; a more logical explanation of the observed motions, he found, was to consider the Sun the pivot of planetary orbits.5 1.

  • The Universe: an Overview
    1 Draft by Paul E. Johnson 2012, 2013 © for UW Astronomy class use only ________________________________________________________________________ Chapter 1 - The Universe: an Overview I roamed the countryside searching for answers to things I did not understand. Why shells existed on the tops of mountains along with the imprints of coral and plants and seaweed usually found in the sea. Why the thunder lasts a longer time than that which causes it and why immediately on its creation the lightning becomes visible to the eye while thunder requires time to travel. How the various circles of water form around the spot which has been struck by a stone and why a bird sustains itself in the air. These questions and other strange phenomena engaged my thought throughout my life. -- Leonardo di Vinci, Renaissance Man Chapter Preview This chapter provides an overview of the Universe and the study of astronomy that will follow in subsequent chapters. You will look at astronomy from multiple perspectives, as a science, from an historical point of few, and from the aspects of time and space. No other branch of science has the overall scope of astronomy: from the subatomic particle to the Universe as a whole, from the moment of creation to the evolution of intelligent life, and from Aristotle to space-based observatories. Key Physical Concepts to Understand: The Scales of Time and Space I. Introduction The purpose of this book is to provide a basic understanding of astronomy as a science. This study will take us on a journey from Earth to the stars, planets, and galaxies that inhabit our Universe.

  • Terrestrial Planets (Bennett Et Al
    Earth and the Geology of the Terrestrial Planets (Bennett et al. Ch. 9) Major Ideas In This Chapter ● Terrestrial planets looked (largely) the same when they were formed. Differences due to geological processes. ● Geological activity is driven by internal heat ● Planetary size plays a large role in retaining heat ● Distance from the Sun, rotation affects erosion ● Crater density can indicate surface age ● Earth has a unique geology Terrestrial Planets ● Compared to Jovian planets: – Smaller size/mass – Large “core” to atmosphere ratio – Higher density – Closer to Sun and closer together – Warmer – Few or no moons – No rings (NASA) Planetary Surfaces and Interiors ● Terrestrial planets + Moon were similar when young – Subjected to heavy bombardment – Differences due to processes that occurred after formation ● Understanding the surface features: planetary geology ● Processes in the interior drive activity at the surface Your book uses “terrestrial worlds” to refer to the terrestrial planets + the Moon.

  • GALILEO and the PHASES of VENUS Abstract
    GALILEO AND THE PHASES OF VENUS Charles-Henri Eyraud Institut National de Recherche Pédagogique (France) Abstract In this article we use Galileo’s letters and drawings to understand his observations of the phases of Venus in 1610-1611. Our article is presented as an exercise for students to understand the conclusions of the great astronomer. PERIODS OF VENUS • Synodical period and phases The synodic period is the time that it takes for the object to reappear at the same point in the sky, relative to the Sun, as observed from Earth; i.e. returns to the same elongation and planetary phase. This is the time that elapses between two successive conjunctions with the Sun. An inferior conjunction occurs when Venus and the Earth lie in a line on the same side of the Sun. When Venus is on the opposite side of the Sun, it is a superior conjunction. The synodic period of Venus is 584 days. The superior conjunction occured on 11th May 1610. Calculate the date of the quadrature, of the inferior conjunction and of the next superior conjunction, supposing the motions of the Earth and Venus are circular and uniform (Figure 2). In fact the next superior conjunction occured on 11th December 1611 and inferior conjunction on 26th February 1611. • Sidereal period The sidereal period is the time that it takes the object to make one full orbit around the Sun, relative to the stars. The sidereal period of the Earth is 365.25 days. Calculate the sidereal period of Venus. PHASES OF VENUS IN GEO AND HELIOCENTRIC MODELS • Phases 1) Determine the phases of Venus in geocentric models, where the Earth is at the center of the universe and planets orbit around (Mercury and Venus “above” or “below” the Sun).

Sipiora, Ph.D. Laura Runge-Gordon, Ph.D Sheila Diecidue, Ph.D Date of Approval: December 12, 2008 Keywords: editing, teaching, rhetoric, computers, writing centers, classrooms, literacy Copyright 2008, Carol Ann Tillema Acknowledgements Though I am fond of the many able instructors who have taught me the art of speaking and writing at the University of South Florida in Tampa, Florida, I especially acknowledge my thesis committee. Dr. Phillip J. Sipiora, author, editor, international lecturer, and beloved professor, has directed me to study profound theories I never studied before and to seek greater rhetorical precision in my writing and in my life. It was he who offered me my first teaching position, changing my life forever. His counseling and his patience with me as a student writer who struggles in the process of producing a product is deeply appreciated. I am indebted to Dr. Laura Runge-Gordon for giving me hope about completing my master’s degree in rhetoric and composition and for agreeing to assist me, a distraught student who had worked years on one project I could not perfect, a student who had long needed help and could not find it, a student who had failed in the endeavor a number of times before. I appreciate her educational and philosophical viewpoints, particularly regarding working across the disciplines in collaborative efforts in the university with the Department of Education.
