The Son of Lamoraal Ulbo De Sitter, a Judge, and Catharine Theodore Wilhelmine Bertling
558 BIOGRAPHIES v.i WiLLEM DE SITTER viT 1872-1934 De Sitter was bom on 6 May 1872 in Sneek (province of Friesland), the son of Lamoraal Ulbo de Sitter, a judge, and Catharine Theodore Wilhelmine Bertling. His father became presiding judge of the court in Arnhem, and that is where De Sitter attended gymna sium. At the University of Groniiigen he first studied mathematics and physics and then switched to astronomy under Jacobus Kapteyn. De Sitter spent two years observing and studying under David Gill at the Cape Obsen'atory, the obseivatory with which Kapteyn was co operating on the Cape Photographic Durchmusterung. De Sitter participated in the program to make precise measurements of the positions of the Galilean moons of Jupiter, using a heliometer. In 1901 he received his doctorate under Kapteyn on a dissertation on Jupiter's satellites: Discussion of Heliometer Observations of Jupiter's Satel lites. De Sitter remained at Groningen as an assistant to Kapteyn in the astronomical laboratory, until 1909, when he was appointed to the chair of astronomy at the University of Leiden. In 1919 he be came director of the Leiden Observatory. He remained in these posts until his death in 1934. De Sitter's work was highly mathematical. With his work on Jupi ter's satellites, De Sitter pursued the new methods of celestial me chanics of Poincare and Tisserand. His earlier heliometer meas urements were later supplemented by photographic measurements made at the Cape, Johannesburg, Pulkowa, Greenwich, and Leiden. De Sitter's final results on this subject were published as 'New Math ematical Theory of Jupiter's Satellites' in 1925. -

Popular Astronomy Lectures in Nineteenth Century Britain
Commercial and Sublime: Popular Astronomy Lectures in Nineteenth Century Britain Hsiang-Fu Huang UCL Department of Science and Technology Studies Thesis submitted for the degree of Doctor of Philosophy (PhD) in History and Philosophy of Science March 2015 2 I, Hsiang-Fu Huang, confirm that the work presented in this thesis is my own. Where information has been derived from other sources, I confirm that this has been indicated in the thesis. Date of signature: 9th March 2015 Supervisors: Joe Cain (UCL) Simon Werrett (UCL) Examiners: Frank A. J. L. James (UCL / Royal Institution of Great Britain) Richard Bellon (Michigan State University) Date of examination: 16th December 2014 3 4 Abstract This thesis discusses the practitioners, sites, curriculums, apparatus and audiences of popular astronomy lecturing in nineteenth-century Britain. Lecturers who were active approximately between 1820 and 1860 are the focus. This thesis emphasises popularisers who were not scientific elites, including C. H. Adams (1803-1871), George Bartley (c. 1782-1858), and D. F. Walker (1778-1865). Activities of private popularisers are compared with those in scientific establishments, such as the Royal Institution. Private entrepreneurs were not inferior to institutional competitors and enjoyed popularity among audiences. Until the 1860s, popular astronomy lecturing was a shared arena of institutional and private popularisers. A theatrical turn occurred in the popular astronomy lecturing trade before 1820. Popularisers moved lectures into theatres and adopted theatrical facilities in performance. They developed large onstage devices, such as the transparent orrery, for achieving scenic and dramatic effects. These onstage astronomical lectures were a phenomenon in the early nineteenth century and were usually performed during Lent. -

REVUE DE SYNTHÈSE : TOME 139 7e SÉRIE N° 3-4 (2018) 267-288 brill.com/rds A Task that Exceeded the Technology: Early Applications of the Computer to the Lunar Three-body Problem Allan Olley* Abstract: The lunar Three-Body problem is a famously intractable problem of Newtonian mechanics. The demand for accurate predictions of lunar motion led to practical approximate solutions of great complexity, constituted by trigonometric series with hundreds of terms. Such considerations meant there was demand for high speed machine computation from astronomers during the earliest stages of computer development. One early innovator in this regard was Wallace J. Eckert, a Columbia University professor of astronomer and IBM researcher. His work illustrates some interesting features of the interaction between computers and astronomy. Keywords: history of astronomy – three body problem – history of computers – Wallace J. Eckert Une tâche excédant la technologie : l’utilisation de l’ordinateur dans le problème lunaire des trois corps Résumé : Le problème des trois corps appliqué à la lune est un problème classique de la mécanique newtonienne, connu pour être insoluble avec des méthodes exactes. La demande pour des prévisions précises du mouvement lunaire menait à des solutions d’approximation pratiques qui étaient d’une complexité considérable, avec des séries tri- gonométriques contenant des centaines de termes. Cela a très tôt poussé les astronomes à chercher des outils de calcul et ils ont été parmi les premiers à utiliser des calculatrices rapides, dès les débuts du développement des ordinateurs modernes. Un innovateur des ces années-là est Wallace J. Eckert, professeur d’astronomie à Columbia University et * Allan Olley, born in 1979, he obtained his PhD-degree from the Institute for the History and Philosophy of Science Technology (IHPST), University of Toronto in 2011. -

EDITED BY WILFRID AIRY, B.A., M.Inst.C.E. 1896 PREFACE. The life of Airy was essentially that of a hard-working, business man, and differed from that of other hard-working people only in the quality and variety of his work. It was not an exciting life, but it was full of interest, and his work brought him into close relations with many scientific men, and with many men high in the State. -

July 26, 1929, will long be remembered in the annals of the Astronomical Society of South Africa, for on the evening of that day it was "At Home" at the Oddfellows' Hall, Plein Street, Cape Town, to the visiting astronomers who were attending the meetings of the British Association. The chair was taken by Mr. A. W. Long, President of the Society, who, in opening the proceedings, said: This gathering of the Astronomical Society of South Africa has been arranged to enable the members to greet the distinguished astronomers and other eminent scien tists interested in astronomy who are visiting South Africa in connection with the meetings of the British Association. We have with us to-night Sir Frank Dyson, the Astronomer Royal; Professor Eddington, Director of the Cambridge University Observatory; Professor Fowl~r, Yarrow Research Professor of the Royal Society; Pro fessor Chapman, of the Imperial College of Science; Professor De Sitter, Director of the Leiden Observatory; Dr. Guthnick, Director of the Berlin-Babelsberg Obser vatory; Dr. K110x-Shaw, Director of the Radcliffe Observatory; Mr. Greaves, of the Greenwich Observa tory; Mr. Wrigley, of the Edinburgh Observatory; Dr. Aston, of Cambridge, and I am pleased to say that at a later stage Lord Rayleigh will also be here. In the name of the Society I extend to these gentlemen a very hearty welcome. We have been familiar with them for a very long time by name, and through their scientific attainments; now we are delighted to have the honour of meeting them in person. -
Astronomer Explores Universe Through Remote-Controlled Telescope 24 May 2016
Astronomer explores universe through remote-controlled telescope 24 May 2016 and bring his students into his research. The telescope is in the Western Europe time zone, which is six hours head of U.S. Central Time. "Because of the time difference, students can see in the afternoon what they'd have to wait until midnight to see here," Keel said. "This opens up new possibilities for classroom experiences in our daytime, as well as making it easier to use the telescope without changing a whole day's schedule." In April and May, Keel took some photos using the reopened telescope, including shots of the globular star cluster M3 in Canes Venatici (the constellation of the Hunting Dogs just south of the Big Dipper) and the planetary nebula M27 (the Dumbbell Nebula) in Vulpecula (the Fox, in the summer Milky Way). Eagle Nebula M16. Taken by Dr. William Keel with the Jacobus Kapteyn Telescope. Access by the astronomers at The University of Alabama to the Jacobus Kapteyn Telescope in the Canary Islands will benefit both research and students at UA. Dr. William Keel, UA professor of astronomy and astrophysics, represents UA on the managing board of a 12-institution consortium called the Southeastern Association for Research in Astronomy. He recently obtained some of the first data with the recently reopened Jacobus Kapteyn Telescope through SARA, which operates the telescope. The 1.0-meter telescope is at an altitude of 2,360 meters at the Observatorio del Roque de los Spiral galaxy M83. Taken by Dr. William Keel with the Muchachos on the Spanish Canary Island of La Jacobus Kapteyn Telescope. -
Former Fellows Biographical Index Part
Former Fellows of The Royal Society of Edinburgh 1783 – 2002 Biographical Index Part Two ISBN 0 902198 84 X Published July 2006 © The Royal Society of Edinburgh 22-26 George Street, Edinburgh, EH2 2PQ BIOGRAPHICAL INDEX OF FORMER FELLOWS OF THE ROYAL SOCIETY OF EDINBURGH 1783 – 2002 PART II K-Z C D Waterston and A Macmillan Shearer This is a print-out of the biographical index of over 4000 former Fellows of the Royal Society of Edinburgh as held on the Society’s computer system in October 2005. It lists former Fellows from the foundation of the Society in 1783 to October 2002. Most are deceased Fellows up to and including the list given in the RSE Directory 2003 (Session 2002-3) but some former Fellows who left the Society by resignation or were removed from the roll are still living. HISTORY OF THE PROJECT Information on the Fellowship has been kept by the Society in many ways – unpublished sources include Council and Committee Minutes, Card Indices, and correspondence; published sources such as Transactions, Proceedings, Year Books, Billets, Candidates Lists, etc. All have been examined by the compilers, who have found the Minutes, particularly Committee Minutes, to be of variable quality, and it is to be regretted that the Society’s holdings of published billets and candidates lists are incomplete. The late Professor Neil Campbell prepared from these sources a loose-leaf list of some 1500 Ordinary Fellows elected during the Society’s first hundred years. He listed name and forenames, title where applicable and national honours, profession or discipline, position held, some information on membership of the other societies, dates of birth, election to the Society and death or resignation from the Society and reference to a printed biography. -

Gravity's Fatal Attraction
Cambridge University Press 978-0-521-71793-9 - Gravity’s Fatal Attraction: Black Holes in the Universe, Second Edition Mitchell Begelman and Martin Rees Frontmatter More information GRAVITY’S FATAL ATTRACTION Black Holes in the Universe Second edition Richly illustrated with the images from observatories on the ground and in space, and computer simulations, this book shows how black holes were discovered, and discusses our current understanding of their role in cosmic evolution. This second edition covers new discoveries made in the past decade, including defi nitive proof of a black hole at the center of the Milky Way, evidence that the expansion of the Universe is accelerating, and the new appreciation of the connection between black holes and galaxy formation. There are entirely new chapters on gamma-ray bursts and cosmic feedback. Begelman and Rees blend theoretical arguments with observa- tional results to demonstrate how both have contributed to the subject. Clear, explanatory illustrations and photographs reveal the strange and amazing workings of our Universe. The engaging style makes this book suitable for introductory undergraduate courses, amateur astronomers, and all readers interested in astronomy and physics. Mitchell Begelman is Chairman of the Department of Astrophysical and Planetary Sciences and Fellow of JILA, at the University of Colorado at Boulder. He has won several awards, including the Guggenheim Fel- lowship, Sloan Research Fellowship, and the American Astronomical Society Warner Prize. Martin Rees is Professor of Cosmology and Astrophysics and Master of Trinity College at Cambridge University, and Astronomer Royal. He is a winner of the Gold Medal of the Royal Astronomical Society and other awards. -
Wallace Eckert
Wallace Eckert Nakumbuka Dk Eckert aliniambia, "Siku moja, kila mtu atakuwa na kompyuta kwenye dawati lao." Macho yangu yalifunguka. Hiyo lazima iwe katika miaka mapema ya 1950’s. Aliona mapema. -Eleanor Krawitz Kolchin, mahojiano ya Huffington Post, Februari 2013. Picha: Karibu 1930, Jalada la Columbiana. Wallace John Eckert, 1902-1971. Pamoja na masomo ya kuhitimu huko Columbia, Chuo Kikuu cha Chicago, na Yale, alipokea Ph.D. kutoka Yale mnamo 1931 chini ya Profesa Ernest William Brown (1866-1938), ambaye alitumia kazi yake katika kuendeleza nadharia ya mwongozo wa mwezi. Maarufu zaidi kwa mahesabu ya mzunguko wa mwezi ambayo yaliongoza misheni ya Apollo kwenda kwa mwezi, Eckert alikuwa Profesa wa Sayansi ya Chuo Kikuu cha Columbia kutoka 1926 hadi 1970, mwanzilishi na Mkurugenzi wa Ofisi ya Taasisi ya Taaluma ya Thomas J. Watson katika Chuo Kikuu cha Columbia (1937-40), Mkurugenzi wa Ofisi ya Amerika ya US Naval Observatory Nautical Almanac (1940-45), na mwanzilishi na Mkurugenzi wa Maabara ya Sayansi ya Watson ya Sayansi katika Chuo Kikuu cha Columbia (1945-1966). Kwanza kabisa, na daima ni mtaalam wa nyota, Eckert aliendesha na mara nyingi alisimamia ujenzi wa mashine za kompyuta zenye nguvu kusuluhisha shida katika mechanics ya mbinguni, haswa ili kuhakikisha, kupanua, na kuboresha nadharia ya Brown. Alikuwa mmoja wa kwanza kutumia mashine za kadi za kuchomwa kwa suluhisho la shida tata za kisayansi. Labda kwa maana zaidi, alikuwa wa kwanza kusasisha mchakato wakati, mnamo 1933-34, aliunganisha mahesabu na kompyuta za IBM kadhaa na mzunguko wa vifaa na vifaa vya muundo wake ili kusuluhisha usawa wa aina, njia ambazo baadaye zilibadilishwa na kupanuliwa kwa IBM ya "Aberdeen "Calculator inayoweza kupatikana ya Udhibiti wa Mpangilio, Punch Kuhesabu elektroniki, Calculator ya Kadi iliyopangwa, na SSEC. -
