INTRODUCTION THE UNIVERSITY OF ILLINOIS ASTRONOMY PROGRAM isa series of six books that introduces astronomy toupper elementary and junior high- school students in a unique way. Theprogram represents a complete restructuring of traditional descriptive school astronomy intoa course of study based on selected major concepts thatare pursued in depth. These basic themes of astronomy have been picked by professional astronomers to give children fundamental and accurate information about the solar system, the stars, and the galaxies. Two subsidiary elements are reflected in this program's approachto the teaching of astronomy. First, there is a strong flavor of history through- out the books. Not. only are fundamental concepts presented, butstu- dents also learn the way in which these conceptswere uncovered by astronomers down through the centuries. Secondly, the interdisciplin- aty nature of astronomy is repeatedly emphasized. Yourstudents will ap- ply principles from several of the physical sciencesas they study these boOks. They will also discover that mathematics isa tool of science. Major concepts in each book are explored primarily throughnumerous student activities as well as through the development of models that explain astronomical phenomena. The physical and mathematical under- pinnings of each book are developed in the early chapters. Later chap- ters are then devoted to the application of these principles to .a variety of areas in astronomy. Within each book, the development is from simple, basic ideas to an understanding of the concepts and principles which the astronomer has established. There has been a vast acquisition of new knowledge 1),, astronomers in 1110 pall III 100 (111011(10s, 111111 1110 1.11111i01S of ostronomyare expanding at tin Increasing rule.

It consists of a humorous 24-minute show and educator’s package. The Orion Educator’s Guide is designed for Planetarians, Teachers, and parents. The information is researched, organized, and laid out so that the educator need not spend hours coming up with lesson plans or labs. This has already been accomplished by certified educators. The guide is written to alleviate the fear of space and the night sky (that many elementary and middle school teachers have) when it comes to that section of the science lesson plan. It is an excellent tool that allows the parents to be a part of the learning experience. The guide is devised in such a way that there are plenty of visuals to assist the educator and student in finding the Winter constellations.

  • 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.

  • Reputations on the Line in Van Diemen's Land
    REPUTATIONS ON THE LINE IN VAN DIEMEN’S LAND: a dissertation on the general theme of the Rule of Law as it emerged in a young penal colony with particular emphasis on the law of defamation by ROSEMARY CONCHITA LUCADOU-WELLS LLB., (Queensland), B.Ed., (Tasmania), MA., (Murdoch), PhD., (Deakin) This thesis is presented for the degree of Master of Laws of Murdoch University, 2012. I declare that this thesis is my own account of my research and contains as its main content work which has not been submitted for a degree at any tertiary education institution. Rosemary Conchita Lucadou-Wells ABSTRACT This research focuses on the development of the jurisprudence of the infant colony of Van Diemen’s Land now known as Tasmania, with particular interest on the law of defamation. During the first thirty years of this British penal colony its population was subject to changes. There were the soldiery, who provided the basis of government headed by a Lieutenant Governor, the indigenous people, the convicts, and gradually an influx of settlers who came enthused by governmental promises of grants of land. In addition to these free settlers there were a selection of convicts who, under a process of something akin to manumission under Roman Law, became upon completion of their sentence, eligible for freedom and possibly a grant of land. There developed a spirit of competition amongst the settlers, each wanted to become more successful than the others. The favourite means of distinguishing oneself was the uttering or publication of damaging words against a person who was perceived to be a rival.

    Accepted for publication in the Astrophysical Journal A Preprint typeset using LTEX style emulateapj v. 12/16/11 CHARACTERIZING THE COOL KOIS IV: KEPLER-32 AS A PROTOTYPE FOR THE FORMATION OF COMPACT PLANETARY SYSTEMS THROUGHOUT THE GALAXY Jonathan J. Swift*,1, John Asher Johnson1,2,3,4, Timothy D. Morton1,3, Justin R. Crepp5, Benjamin T. Montet1, Daniel C. Fabrycky6,7, and Philip S. Muirhead1 Accepted for publication in the Astrophysical Journal ABSTRACT The Kepler space telescope has opened new vistas in exoplanet discovery space by revealing popula- tions of Earth-sized planets that provide a new context for understanding planet formation. Approx- imately 70% of all stars in the Galaxy belong to the diminutive M dwarf class, several thousand of which lie within Kepler’s field of view, and a large number of these targets show planet transit signals. The Kepler M dwarf sample has a characteristic mass of 0.5 M⊙ representing a stellar population twice as common as Sun-like stars. Kepler-32 is a typical star in this sample that presents us with a rare opportunity: five planets transit this star giving us an expansive view of its architecture. All five planets of this compact system orbit their host star within a distance one third the size of Mercury’s orbit with the innermost planet positioned a mere 4.3 stellar radii from the stellar photosphere. New observations limit possible false positive scenarios allowing us to validate the entire Kepler-32 system making it the richest known system of transiting planets around an M dwarf.

  • 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.

  • Dutch Art, 17Th Century
    Dutch Art, 17th century The Dutch Golden Age was a period in the history of the Netherlands, roughly spanning the 17th century, in which Dutch trade, science, military, and art were among the most acclaimed in the world. The first section is characterized by the Thirty Years' War, which ended in 1648. The Golden Age continued in peacetime during the Dutch Republic until the end of the century. The transition by the Netherlands to the foremost maritime and economic power in the world has been called the "Dutch Miracle" by historian K. W. Swart. Adriaen van Ostade (1610 – 1685) was a Dutch Golden Age painter of genre works. He and his brother were pupils of Frans Hals and like him, spent most of their lives in Haarlem. A01 The Painter in his Workshop 1633 A02 Resting Travelers 1671 David Teniers the Younger (1610 – 1690) was a Flemish painter, printmaker, draughtsman, miniaturist painter, staffage painter, copyist and art curator. He was an extremely versatile artist known for his prolific output. He was an innovator in a wide range of genres such as history, genre, landscape, portrait and still life. He is now best remembered as the leading Flemish genre painter of his day. Teniers is particularly known for developing the peasant genre, the tavern scene, pictures of collections and scenes with alchemists and physicians. A03 Peasant Wedding 1650 A04 Archduke Leopold Wilhelm in his gallery in Brussels Gerrit Dou (1613 – 1675), also known as Gerard and Douw or Dow, was a Dutch Golden Age painter, whose small, highly polished paintings are typical of the Leiden fijnschilders.

  • Vermeer and the Masters of Genre Painting: Inspiration and Rivalry Wednesday, November 8, 2017 the Exhibition Is Organized by the 4:30 – 7:30 P.M
    vermeer and the masters of genre painting national gallery of art october 22, 2017 – january 21, 2018 AMONG THE MOST ENDURING IM AGES of the Dutch Golden Age are genre paintings, or scenes of daily life, from the third quarter of the seventeenth century. Made during a time of unparalleled inno- vation and prosperity, these exquisite portrayals of refined Dutch society — elegant men and women writing letters, playing music, and tending to their daily rituals — present a genteel world that is extraordinarily appealing. Today, Johannes Vermeer is the most cel- ebrated of these painters thanks to the beauty and tranquility of his images. Yet other masters, among them Gerard ter Borch, Gerrit Dou, Frans van Mieris, and Gabriel Metsu, also created works that are remarkably similar in style, subject matter, and technique. The visual connections between these artists’ paintings suggest a robust atmosphere of innovation and exchange — but to what extent did they inspire each other’s work, and to what extent did they follow their own artistic evolution? This exhibition brings together almost seventy paintings made between about 1655 and 1680 to explore these questions and celebrate the inspiration, rivalry, and artistic evolution of Vermeer and other masters of genre painting.
