Martian Crater Morphology
ANALYSIS OF THE DEPTH-DIAMETER RELATIONSHIP OF MARTIAN CRATERS A Capstone Experience Thesis Presented by Jared Howenstine Completion Date: May 2006 Approved By: Professor M. Darby Dyar, Astronomy Professor Christopher Condit, Geology Professor Judith Young, Astronomy Abstract Title: Analysis of the Depth-Diameter Relationship of Martian Craters Author: Jared Howenstine, Astronomy Approved By: Judith Young, Astronomy Approved By: M. Darby Dyar, Astronomy Approved By: Christopher Condit, Geology CE Type: Departmental Honors Project Using a gridded version of maritan topography with the computer program Gridview, this project studied the depth-diameter relationship of martian impact craters. The work encompasses 361 profiles of impacts with diameters larger than 15 kilometers and is a continuation of work that was started at the Lunar and Planetary Institute in Houston, Texas under the guidance of Dr. Walter S. Keifer. Using the most ‘pristine,’ or deepest craters in the data a depth-diameter relationship was determined: d = 0.610D 0.327 , where d is the depth of the crater and D is the diameter of the crater, both in kilometers. This relationship can then be used to estimate the theoretical depth of any impact radius, and therefore can be used to estimate the pristine shape of the crater. With a depth-diameter ratio for a particular crater, the measured depth can then be compared to this theoretical value and an estimate of the amount of material within the crater, or fill, can then be calculated. The data includes 140 named impact craters, 3 basins, and 218 other impacts. The named data encompasses all named impact structures of greater than 100 kilometers in diameter. -

HUXLEY BOMBIERI and IWANIEC [BI1, BI2] obtained 9 = 9/56 for the Lindelof exponent (the least 9 for which the Riemann zeta function satisfies C(l/2 + i<) = 0(te+£) as <->oo.) They remarked that their method might not be special to the Lindelof problem; in fact, as the saying goes, "they wrought [worked] better than they knew". To show that one property is uniformly distributed with respect to another property, one forms exponential sums 2M-1 5 = e{f[m)) , (1) M where e(x) = exp 2nix, f(m) = TF(m/M) with F(x) in the function class Cn[l — <5,2 + 6] for some 6 > 0 and n > 4. The case F(x) = log x gives Dirichlet series. If F(x) is a polynomial of degree d with rational coefficients, denominator g, and if T = Md, then the sum 5 is approximately MSJq , where Sq is a complete exponential sum with denominator q. -
Mosasaurs from Germany – a Brief History of the First 100 Years of Research
Netherlands Journal of Geosciences —– Geologie en Mijnbouw | 94 – 1 | 5-18 | 2015 doi: 10.1017/njg.2014.16 Mosasaurs from Germany – a brief history of the first 100 years of research Sven Sachs1,*,JahnJ.Hornung2 &MikeReich2,3 1 Im Hof 9, 51766 Engelskirchen, Germany 2 Georg-August University Gottingen,¨ Geoscience Centre, Department of Geobiology, Gottingen,¨ Germany 3 Georg-August University Gottingen,¨ Geoscience Museum, Gottingen,¨ Germany * Corresponding author. Email: [email protected] Manuscript received: 30 December 2013, accepted: 26 May 2014 Abstract In Germany, mosasaur remains are very rare and only incompletely known. However, the earliest records date back to the 1830s, when tooth crowns werefoundinthechalkoftheIsleofRugen.¨ A number of prominent figures in German palaeontology and geosciences of the 19th and 20th centuries focused on these remains, including, among others, Friedrich von Hagenow, Hermann von Meyer, Andreas Wagner, Hanns Bruno Geinitz and Josef Pompeckj. Most of these works were only short notes, given the scant material. However, the discovery of fragmentary cranial remains in Westphalia in 1908 led to a more comprehensive discussion, which is also of historical importance, as it illustrates the discussions on the highly controversial and radical universal phylogenetic theory proposed by Gustav Steinmann in 1908. This theory saw the existence of continuous lines of descent, evolving in parallel, and did not regard higher taxonomic units as monophyletic groups but as intermediate paraphyletic stages of evolution. In this idea, nearly all fossil taxa form part of these lineages, which extend into the present time, and natural extinction occurs very rarely, if ever. In Steinmann’s concept, mosasaurs were not closely related to squamates but formed an intermediate member in a anagenetic chain from Triassic thalattosaurs to extant baleen whales. -

Appendix I Lunar and Martian Nomenclature
APPENDIX I LUNAR AND MARTIAN NOMENCLATURE LUNAR AND MARTIAN NOMENCLATURE A large number of names of craters and other features on the Moon and Mars, were accepted by the IAU General Assemblies X (Moscow, 1958), XI (Berkeley, 1961), XII (Hamburg, 1964), XIV (Brighton, 1970), and XV (Sydney, 1973). The names were suggested by the appropriate IAU Commissions (16 and 17). In particular the Lunar names accepted at the XIVth and XVth General Assemblies were recommended by the 'Working Group on Lunar Nomenclature' under the Chairmanship of Dr D. H. Menzel. The Martian names were suggested by the 'Working Group on Martian Nomenclature' under the Chairmanship of Dr G. de Vaucouleurs. At the XVth General Assembly a new 'Working Group on Planetary System Nomenclature' was formed (Chairman: Dr P. M. Millman) comprising various Task Groups, one for each particular subject. For further references see: [AU Trans. X, 259-263, 1960; XIB, 236-238, 1962; Xlffi, 203-204, 1966; xnffi, 99-105, 1968; XIVB, 63, 129, 139, 1971; Space Sci. Rev. 12, 136-186, 1971. Because at the recent General Assemblies some small changes, or corrections, were made, the complete list of Lunar and Martian Topographic Features is published here.

Astronautique
Astronautique par Jean CHEYMOL * Le mot et la chose ne surprennent plus les jeunes d'aujourd'hui. Télévi sion, journaux et surtout romans d'anticipation les ont saturés de ces faits qui n'épatent guère plus que les gens de notre génération. En allait-il autrement il y a cinquante ans ? A cette époque, même après avoir lu Jules Verne les allusions aux voyages dans la Lune ne faisaient pas sérieux ! Pour ma part je dois faire amende honorable à cause de mon incrédulité moqueuse. Parcourant vers 1928 un journal d'information scientifique, j'y découvris avec effarement la création d'un prix international d'Astronautique [Esnault-Pelterie (1)] devant être attribué par la Société Astronomique de France « au meilleur travail scientifique original, théorique ou expérimental, capable de faire progresser l'une des questions dont dépend la réalisation de la navigation intersidérale ou d'augmenter les connaissances humaines dans l'une des branches touchant à la science astronautique ». Fusée pour aller dans les astres ! Pourquoi pas pour entrer en contact avec leurs habitants ! Vous voyez d'ici l'ironie facile en salle de garde envers les lunatiques de la Société Astronautique de France et les créateurs d'une telle récompense (2). Et cependant en notre temps la prospection vers les planètes progres sent d'année en année : (*) Séance de la Société Française d'Histoire de la Médecine du 22 avril 1972, jour de l'alunissage d'Apolo XVI. (1) Le mot « astronautique » fut donné par J.H. Rosny aîné, alors Président de l'Académie Goncourt et membre du Comité d'attribution du prix.
