Karl Weierstraß – Zum 200. Geburtstag „Alles Im Leben Kommt Doch Leider Zu Spät“ Reinhard Bölling Universität Potsdam, Institut Für Mathematik Prolog Nunmehr Im 74
1 Karl Weierstraß – zum 200. Geburtstag „Alles im Leben kommt doch leider zu spät“ Reinhard Bölling Universität Potsdam, Institut für Mathematik Prolog Nunmehr im 74. Lebensjahr stehend, scheint es sehr wahrscheinlich, dass dies mein einziger und letzter Beitrag über Karl Weierstraß für die Mediathek meiner ehemaligen Potsdamer Arbeitsstätte sein dürfte. Deshalb erlaube ich mir, einige persönliche Bemerkungen voranzustellen. Am 9. November 1989 ging die Nachricht von der Öffnung der Berliner Mauer um die Welt. Am Tag darauf schrieb mir mein Freund in Stockholm: „Herzlich willkommen!“ Ich besorgte das damals noch erforderliche Visum in der Botschaft Schwedens und fuhr im Januar 1990 nach Stockholm. Endlich konnte ich das Mittag- Leffler-Institut in Djursholm, im nördlichen Randgebiet Stockholms gelegen, besuchen. Dort befinden sich umfangreiche Teile des Nachlasses von Weierstraß und Kowalewskaja, die von Mittag-Leffler zusammengetragen worden waren. Ich hatte meine Arbeit am Briefwechsel zwischen Weierstraß und Kowalewskaja, die meine erste mathematikhistorische Publikation werden sollte, vom Inhalt her abgeschlossen. Das Manuskript lag in nahezu satzfertiger Form vor und sollte dem Verlag übergeben werden. Geradezu selbstverständlich wäre es für diese Arbeit gewesen, die Archivalien im Mittag-Leffler-Institut zu studieren. Aber auch als Mitarbeiter des Karl-Weierstraß- Institutes für Mathematik in Ostberlin gehörte ich nicht zu denen, die man ins westliche Ausland reisen ließ. – Nun konnte ich mir also endlich einen ersten Überblick über die Archivalien im Mittag-Leffler-Institut verschaffen. Ich studierte in jenen Tagen ohne Unterbrechung von morgens bis abends Schriftstücke, Dokumente usw. aus dem dortigen Archiv, denn mir stand nur eine Woche zur Verfügung. Am zweiten Tag in Djursholm entdeckte ich unter Papieren ganz anderen Inhalts einige lose Blätter, die Kowalewskaja beschrieben hatte. -
Atomic History Project Background: If You Were Asked to Draw the Structure of an Atom, What Would You Draw?
Atomic History Project Background: If you were asked to draw the structure of an atom, what would you draw? Throughout history, scientists have accepted five major different atomic models. Our perception of the atom has changed from the early Greek model because of clues or evidence that have been gathered through scientific experiments. As more evidence was gathered, old models were discarded or improved upon. Your task is to trace the atomic theory through history. Task: 1. You will create a timeline of the history of the atomic model that includes all of the following components: A. Names of 15 of the 21 scientists listed below B. The year of each scientist’s discovery that relates to the structure of the atom C. 1- 2 sentences describing the importance of the discovery that relates to the structure of the atom Scientists for the timeline: *required to be included • Empedocles • John Dalton* • Ernest Schrodinger • Democritus* • J.J. Thomson* • Marie & Pierre Curie • Aristotle • Robert Millikan • James Chadwick* • Evangelista Torricelli • Ernest • Henri Becquerel • Daniel Bernoulli Rutherford* • Albert Einstein • Joseph Priestly • Niels Bohr* • Max Planck • Antoine Lavoisier* • Louis • Michael Faraday • Joseph Louis Proust DeBroglie* Checklist for the timeline: • Timeline is in chronological order (earliest date to most recent date) • Equal space is devoted to each year (as on a number line) • The eight (8) *starred scientists are included with correct dates of their discoveries • An additional seven (7) scientists of your choice (from -
Physics of Gases and Phenomena of Heat Evangelista Torricelli (1608-1647)
Physics of gases and phenomena of heat Evangelista Torricelli (1608-1647) ”...We have made many vessels of glass like those shown as A and B and with tubes two cubits long. These were filled with quicksilver, the open end was closed with the finger, and they were then inverted in a vessel where there was quicksilver C; then we saw that an empty space was formed and that nothing happened in the vessel when this space was formed; the tube between A and D remained always full to the height of a cubit and a quarter and an inch high... Water also in a similar tube, though a much longer one, will rise to about 18 cubits, that is, as much more than quicksilver does as quicksilver is heavier than water, so as to be in equilibrium with the same cause which acts on the one and the other...” Letter to Michelangelo Ricci, June 11, 1644 Evangelista Torricelli (1608-1647) ”We live immersed at the bottom of a sea of elemental air, which by experiment undoubtedly has weight, and so much weight that the densest air in the neighbourhood of the surface of the earth weighs about one four-hundredth part of the weight of water...” Letter to Michelangelo Ricci, June 11, 1644 In July 1647 Valeriano Magni performed experiments on the vacuum in the presence of the King of Poland at the Royal Castle in Warsaw Blaise Pascal (1623-1662) ”I am searching for information which could help decide whether the action attributed to horror vacui really results from it or perhaps is caused by gravity and the pressure of air. -

A Century of Mathematics in America, Peter Duren Et Ai., (Eds.), Vol
Garrett Birkhoff has had a lifelong connection with Harvard mathematics. He was an infant when his father, the famous mathematician G. D. Birkhoff, joined the Harvard faculty. He has had a long academic career at Harvard: A.B. in 1932, Society of Fellows in 1933-1936, and a faculty appointmentfrom 1936 until his retirement in 1981. His research has ranged widely through alge bra, lattice theory, hydrodynamics, differential equations, scientific computing, and history of mathematics. Among his many publications are books on lattice theory and hydrodynamics, and the pioneering textbook A Survey of Modern Algebra, written jointly with S. Mac Lane. He has served as president ofSIAM and is a member of the National Academy of Sciences. Mathematics at Harvard, 1836-1944 GARRETT BIRKHOFF O. OUTLINE As my contribution to the history of mathematics in America, I decided to write a connected account of mathematical activity at Harvard from 1836 (Harvard's bicentennial) to the present day. During that time, many mathe maticians at Harvard have tried to respond constructively to the challenges and opportunities confronting them in a rapidly changing world. This essay reviews what might be called the indigenous period, lasting through World War II, during which most members of the Harvard mathe matical faculty had also studied there. Indeed, as will be explained in §§ 1-3 below, mathematical activity at Harvard was dominated by Benjamin Peirce and his students in the first half of this period. Then, from 1890 until around 1920, while our country was becoming a great power economically, basic mathematical research of high quality, mostly in traditional areas of analysis and theoretical celestial mechanics, was carried on by several faculty members. -

A la memoria de Fernando del Valle Vázquez, de su hijo agradecido. Y a Silvia Aguirrezábal Guerrero. LIBRO PRIMERO. EXHORDIVM. A MODO DE INTRODUCCIÓN. ería necesario un largo estudio para establecer con detalle las condiciones en las cuales fueron compuestas, en primer lugar, las S Quintas Objeciones de Pierre Gassendi, Prepósito de la Iglesia de Digne y agudísimo Filósofo, designadas de esta manera en un Índice redactado por Mersenne, y después las Instancias 1, fechadas el 15 de marzo de 1642, pero que seguramente comenzaron a difundirse durante el invierno anterior . Son palabras de Bernard Rochot 2 y con ellas comenzaba la introducción de su traducción francesa de la Petri Gassendi Disquisitio metaphysica . Esta tesis no es sino el cumplimiento de este anhelo de Rochot, que ha ya mucho convertimos en propio, si bien hemos ampliado los límites de la empresa, toda vez que este trabajo no se contenta con plasmar los acontecimientos que dieron lugar a la aparición de ambos escritos, sino que incluye el análisis pormenorizado de ellos, e incluso el de las escuetas réplicas de Descartes a las Instancias . Es la primera vez que se recorre el ciclo completo de los argumentos de la querella, hasta su cierre con la Carta a Clerselier . Eran años de carrera cuando estudiábamos, bajo la tutela del Doctor D. Marcelino Rodríguez Donís, las Meditationes de prima philosophia , con sus siete Objeciones y Respuestas y, de entre ellas, las agrias Objectiones quintae sobresalían, a nuestro juicio, muy por encima de las demás, a pesar de que uno de los siete objetores fuese el ínclito Thomas Hobbes 3. -
