What is Science? > > > > > > > > > > > > > > Discussion Prompts • Ask students to define “science.” Then, look up the word in a dictionary. • Name some major branches of science. (biology, chemistry, physics, astronomy, earth science) • What are some subdisciplines of these sciences? (e.g., botany and zoology within biology) • What are some ways the major branches of science relate to each other? (e.g., astronomy uses principles of physics; biology and earth sciences both explore the earth’s biomes and ecosystems; chemistry underlies all areas of science) • Introduce the Dewey Decimal Classification System 500s, projecting a chart and reviewing at least the tens groupings for major divisions. Explain how the system helps us find DISCUSSION PROMPTS information in libraries. • Ask for definitions of “scientific method” or “scientific inquiry.” Explain that while the basics of the scientific method (the objective, systematic “hypothesize and test” approach to gaining knowledge) are well known, there isn’t one authoritative set of steps that everyone accepts. • Talk about some formulations of scientific steps, like those in The Magic School Bus and The Science Fair Expedition and Think Like a Scientist in the Gym. • Choose or develop a set of steps for the class to use, and make up a mnemonic phrase to help remember it. • End by reading the poem “Scientific Method at the Bat,” from Jon Scieszka’s Science Verse.

Poverty, Charity and the Papacy in The
TRICLINIUM PAUPERUM: POVERTY, CHARITY AND THE PAPACY IN THE TIME OF GREGORY THE GREAT AN ABSTRACT SUBMITTED ON THE FIFTEENTH DAY OF MARCH, 2013 TO THE DEPARTMENT OF HISTORY IN PARTIAL FULFILLMENT OF THE REQUIREMENTS OF THE SCHOOL OF LIBERAL ARTS OF TULANE UNIVERSITY FOR THE DEGREE OF DOCTOR OF PHILOSOPHY BY ___________________________ Miles Doleac APPROVED: ________________________ Dennis P. Kehoe, Ph.D. Co-Director ________________________ F. Thomas Luongo, Ph.D. Co-Director ________________________ Thomas D. Frazel, Ph.D AN ABSTRACT This dissertation examines the role of Gregory I (r. 590-604 CE) in developing permanent ecclesiastical institutions under the authority of the Bishop of Rome to feed and serve the poor and the socio-political world in which he did so. Gregory’s work was part culmination of pre-existing practice, part innovation. I contend that Gregory transformed fading, ancient institutions and ideas—the Imperial annona, the monastic soup kitchen-hospice or xenodochium, Christianity’s “collection for the saints,” Christian caritas more generally and Greco-Roman euergetism—into something distinctly ecclesiastical, indeed “papal.” Although Gregory has long been closely associated with charity, few have attempted to unpack in any systematic way what Gregorian charity might have looked like in practical application and what impact it had on the Roman Church and the Roman people. I believe that we can see the contours of Gregory’s initiatives at work and, at least, the faint framework of an organized system of ecclesiastical charity that would emerge in clearer relief in the eighth and ninth centuries under Hadrian I (r. 772-795) and Leo III (r.

THE 570S COUPE: the FIRST MODEL in the NEW Mclaren SPORTS SERIES
Media information October 2015 THE 570S COUPE: THE FIRST MODEL IN THE NEW McLAREN SPORTS SERIES The Sports Series completes the McLaren three tier model range, with the 570S Coupe priced from $184,900 The highest power output and lightest car in the sports car segment by almost 331 lbs (150kg) means a class-leading power-to-weight ratio of 5 lbs per hp (434PS per ton) The 570S Coupe demonstrates five key characteristics – aerodynamics and design, minimized weight, craftsmanship, day-to-day usability and driving involvement – to create the most attainable McLaren model to date The McLaren 570S Coupe is the first – and highest powered – model launched in the recently announced Sports Series. Following its global debut at the New York International Auto Show in April 2015, the new model range marks the entry of McLaren into the luxury sports car market, introducing race-derived technologies and supercar performance in a package which is very much a pure McLaren. Lightweight construction, including the use of a carbon fiber chassis, recognizable design values and a comprehensive specification list ensures a class-leading offering, and as uncompromised as is expected from a McLaren. With pricing starting at $184,900, the 570S Coupe is available to order now with deliveries in the U.S. starting before the end of 2015. The latest addition to the range completes the three tier model strategy for McLaren alongside the Super Series and Ultimate Series. The Sports Series is the most usable and attainable model to wear a McLaren badge to date, but it retains the core design and dynamic focus that ensures it is still worthy of the iconic name.

Jordanes and the Invention of Roman-Gothic History Dissertation
Empire of Hope and Tragedy: Jordanes and the Invention of Roman-Gothic History Dissertation Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Brian Swain Graduate Program in History The Ohio State University 2014 Dissertation Committee: Timothy Gregory, Co-advisor Anthony Kaldellis Kristina Sessa, Co-advisor Copyright by Brian Swain 2014 Abstract This dissertation explores the intersection of political and ethnic conflict during the emperor Justinian’s wars of reconquest through the figure and texts of Jordanes, the earliest barbarian voice to survive antiquity. Jordanes was ethnically Gothic - and yet he also claimed a Roman identity. Writing from Constantinople in 551, he penned two Latin histories on the Gothic and Roman pasts respectively. Crucially, Jordanes wrote while Goths and Romans clashed in the imperial war to reclaim the Italian homeland that had been under Gothic rule since 493. That a Roman Goth wrote about Goths while Rome was at war with Goths is significant and has no analogue in the ancient record. I argue that it was precisely this conflict which prompted Jordanes’ historical inquiry. Jordanes, though, has long been considered a mere copyist, and seldom treated as an historian with ideas of his own. And the few scholars who have treated Jordanes as an original author have dampened the significance of his Gothicness by arguing that barbarian ethnicities were evanescent and subsumed by the gravity of a Roman political identity. They hold that Jordanes was simply a Roman who can tell us only about Roman things, and supported the Roman emperor in his war against the Goths.

The Aksumites in South Arabia: an African Diaspora of Late Antiquity
Chapter 11 The Aksumites in South Arabia: An African Diaspora of Late Antiquity George Hatke 1 Introduction Much has been written over the years about foreign, specifically western, colo- nialism in sub-Saharan Africa, as well as about the foreign peoples, western and non-western alike, who have settled in sub-Saharan Africa during the modern period. However, although many large-scale states rose and fell in sub- Saharan Africa throughout pre-colonial times, the history of African imperial expansion into non-African lands is to a large degree the history of Egyptian invasions of Syria-Palestine during Pharaonic and Ptolemaic times, Carthagin- ian (effectively Phoenician) expansion into Sicily and Spain in the second half of the first millennium b.c.e, and the Almoravid and Almohad invasions of the Iberian Peninsula during the Middle Ages. However, none of this history involved sub-Saharan Africans to any appreciable degree. Yet during Late Antiquity,1 Aksum, a sub-Saharan African kingdom based in the northern Ethi- opian highlands, invaded its neighbors across the Red Sea on several occasions. Aksum, named after its capital city, was during this time an active participant in the long-distance sea trade linking the Mediterranean with India via the Red Sea. It was a literate kingdom with a tradition of monumental art and ar- chitecture and already a long history of contact with South Arabia. The history of Aksumite expansion into, and settlement in, South Arabia can be divided into two main periods. The first lasts from the late 2nd to the late 3rd century 1 Although there is disagreement among scholars as to the chronological limits of “Late Antiq- uity”—itself a modern concept—the term is, for the purposes of the present study, used to refer to the period from ca.

The Geopolitics on the Silk Road
109 The Geopolitics on the Silk Road: Resurveying the Relationship of the Western Türks with Byzantium through Their Diplomatic Communications Li Qiang, Stefanos Kordosis* The geopolitics pertaining to the Silk Road network in the period from the 6th to the 7th cen- tury (the final, albeit important, period of Late Antiquity) was intertwined with highly strate- gic dimensions.1 The frequent arrival of hoards of nomadic peoples from inner Eurasia at the borders of the existing sedentary empires and their encounters and interactions formed the complicated political ecology of the period. These empires attempted to take advantage of the newly shaped situation arising after such great movements strategically, each in their own interest. How did they achieve their goals and what problems were they confronted with? In this paper, I will focus on the relations the Western Türks had with Byzantium and use it as an example in order to resurvey these complicated geopolitics. In the first part, attention will be given to the collection of Byzantine literature concerning the Western Türks. Then, on the basis of the sources, the four main exchanges of delegations between the Western Türks and Byzantium will be discussed, in which the important status of the 563 embassy – as it was the first Türk delegation sent to Byzantium – will be emphasized. The possible motives behind the dispatch of the delegations and the repercussions they had will be presented. Finally, through reviewing the diplomatic communication between the Western Türks and Byzantium, attention will be turned to the general picture of geopolitics along the Silk Road, claiming that the great empire of the West – similar to today’s superpowers – by means of their resources (mainly diplomacy) manipulated the geopolitics on the Silk Road, especially the nomadic people pursuing their own survival and interests, who were only treated as piec- es on a chessboard for keeping the balance with the rest of the superpowers.

This painful recycling of history should make him—and us—want to know what unhealable wound, what recurrent pathology, what cause too deep for journalists and politicians to discern draws men and women to their deaths again and again in such a place. The history of Rome, as has often been true in the past, has much to teach us.
