No início, a observação do movimento Hemerson Brandão [email protected] gradual dos corpos celestes ajudou aos primórdios da civilização na contagem e regularização do tempo, e por esse motivo, a Astronomia é considerada uma das Diagramadores Rodolfo Saccani ciências mais antigas da humanidade. [email protected] Foi na Antiga Grécia, por volta de 450 a.C., que os Sharon Camargo gregos começaram a fazer os primeiros registros [email protected] detalhados do movimento dos astros, tentando entender Hemerson Brandão [email protected] as suas causas. Ricas histórias mitológicas explicavam o porque de cada constelação no céu, enquanto filósofos debatiam uma explicação para o movimento Redatores Audemário Prazeres dos astros errantes, os planetas.

Inhaltsverzeichnis
Nachlass EDUARD SCHÖNFELD (1828-1891) Inhaltsverzeichnis Bearbeitet von Anne Hoffsümmer und Lea Korb Bonn, 2017 – 2018 zuletzt aktualisiert am 09.09.2020 Eduard Schönfeld wurde am 22.12.1828 in Hildburghausen geboren, wo er bis zu seinem Abitur 1847 die Schule besuchte. Er war Kind einer jüdischen Familie, trat jedoch nach seinem Schulabschluss dem evangelischen Glauben bei. Auf Anraten seines Vaters studierte Schönfeld zunächst Bauwesen, entschied sich aber nach kurzer Zeit für die Naturwissenschaften und begann, in Marburg bei dem Gauß-Schüler Christian Ludwig Gerling unter anderem Astronomie zu studieren. Nachdem Schönfeld auf einer Reise nach Bonn Bekanntschaft mit Friedrich Wilhelm August Argelander gemacht hatte, entschloss er sich, das Studium der Astronomie 1852 in Bonn fortzusetzen. Dort erhielt er schon ein Jahr später eine Stelle als Assistent, durch die er die Möglichkeit erhielt, gemeinsam mit Adalbert Krüger an der bekannten „Bonner Durchmusterung“, Argelanders großem Projekt, mitzuwirken. Mit einer Abhandlung über die Bahnelemente des Kleinplaneten Thetis promovierte Schönfeld 1854. Seine Habilitation folgte drei Jahre später. Eduard Schönfeld zog 1859 nach Mannheim, um dort die Stelle als Direktor der Mannheimer Sternwarte anzutreten. In der Mannheimer Zeit widmete er sich unter anderem der Bestimmung der Positionen von Nebelflecken mithilfe des Ringmikrometer. Eduard Schönfeld war Mitbegründer und Vorstandsmitglied der Astronomischen Gesellschaft sowie lange Jahre ihr Schriftführer und Herausgeber der Vierteljahrsschrift. Nach Argelanders Tod im Jahr 1875 übernahm Schönfeld dessen Stelle als Direktor der Bonner Sternwarte und ergänzte die Arbeit zur Bonner Durchmusterung, indem er die Bereiche -2°- -23° der südlichen Deklination erforschte. 1883 wurde er Geheimer Regierungsrat und war 1887/88 Rektor der Universität Bonn. -
Inventing the Endless Frontier: the Effects of the World War II Research
Inventing the Endless Frontier: The Effects of the World War II Research Effort on Post-war Innovation∗ Daniel P. Gross† Bhaven N. Sampat‡ Harvard Business School and NBER Columbia University and NBER June 2, 2020 first draft: June 2, 2020 Abstract: During World War II, the U.S. government launched an unprecedented effort to mobi- lize science for war: the newly-established Office of Scientific Research and Development (OSRD) entered thousands of R&D contracts with industrial and academic contractors, spending one to two orders of magnitude more than what the government was previously investing in science. In this pa- per, we study the long-run effects of the OSRD-supported research effort on U.S. invention. Using data on all OSRD contracts, we show that these investments had large effects on the direction and location of U.S. invention and high-tech industrial employment, setting in motion agglomeration forces which shaped the technology clusters of the postwar era. Our results demonstrate the effects of a large, mission-driven government R&D program on the growth of domestic technology clusters and long-run technological progress.

Hutcheon Submitted in accordance with the requirements for the degree of Doctor of Philosophy. Research Institute: School of Environmental and Physical Sciences and Applied Mathematics. University of Keele June 2015 ii iii Abstract This thesis is in three parts: 1) a kinematical study of exoplanet host stars, 2) a study of the detached eclipsing binary V1094 Tau and 3) and observations of other eclipsing binaries. Part I investigates kinematical biases between two methods of detecting exoplanets; the ground based transit and radial velocity methods. Distances of the host stars from each method lie in almost non-overlapping groups. Samples of host stars from each group are selected. They are compared by means of matching comparison samples of stars not known to have exoplanets. The detection methods are found to introduce a negligible bias into the metallicities of the host stars but the ground based transit method introduces a median age bias of about -2 Gyr. -
