Extractions: The Fundamental Theorem of Algebra (FTA) states Every polynomial equation of degree n with complex coefficients has n roots in the complex numbers. In fact there are many equivalent formulations: for example that every real polynomial can be expressed as the product of real linear and real quadratic factors. Early studies of equations by al'Khwarizmi (c 800) only allowed positive real roots and the FTA was not relevant. Cardan was the first to realise that one could work with quantities more general than the real numbers. This discovery was made in the course of studying a formula which gave the roots of a cubic equation. The formula when applied to the equation x = 15x + 4 gave an answer involving -121 yet Cardan knew that the equation had x = 4 as a solution. He was able to manipulate with his 'complex numbers' to obtain the right answer yet he in no way understood his own mathematics. Bombelli , in his Algebra , published in 1572, was to produce a proper set of rules for manipulating these 'complex numbers'.

Extractions: Archival material related to Jakob Nielsen A collection of Jakob Nielsen papers is located in the Archive , Institute for Mathematical Science, University of Copenhagen. An inventory of the papers is accessible in Danish and English at the homepages of the Archive. The Nielsen papers are a collection of mathematical reprints, which Nielsen received during his career from various mathematicians. In some cases there are also press clippings related to a person (mainly the Danish mathematicians) or correspondence (see below ). There may also be manuscripts (see below) , but mainly manuscripts by others than Nielsen. Archive no. 6036 at The National Archives, Copenhagen is material from Nielsen from the period 1945-57. There are 3 boxes deposited in 1982. They are inaccessible after the 50 years rule (application needed to get access) and have not been registered. The content is: correspondence, summary of meetings etc. from Nielsen's activities at UNESCO. The following manuscripts written by Nielsen are in the Jakob Nielsen papers (box numbers refer to that collection).

Extractions: KØBENHAVNS UNIVERSITET Arkivets hjemmeside Samlingsoversigt Jakob Nielsen papirer Kort beskrivelse: Denne samling af Jakob Nielsens papirer består for størstedelen af særtryk, som Nielsen har modtaget fra andre videnskabsfolk og sorteret efter forfatter. Udover særtrykkene er der i forbindelse med nogle af personerne breve, manuskripter, ansøgninger og andet. Alt materiale er fra ca. 1890-1959 og på en lang række sprog hvad angår særtrykkene. Det øvrige materiale er dog fortrinsvis på dansk eller tysk. Omfang: Samlingen omfatter 79 arkivkasser, hvoraf de første 25 er almindelige arkivkasser og resten er Nielsens originale kasser. Overdragelse: Samlingen befandt sig i Matematisk biblioteks kælder i E-bygningen på H. C. Ørsted Institutet i efteråret 1996. Det vides ikke, hvornår eller hvordan den er kommet der. I juli 1999 blev der tilføjet fotokopier af materiale fra Staatsarchiv Hamburg til box 10 Klausuler: Ingen.

Extractions: (Frederick S. Litten) Hermann Strebel Lichttherapeut und Sonnenforscher [Hermann Strebel light therapist and sun observer]; in: Sterne und Weltraum , 31. Jg., Heft 3, 1992, S. 154-157. Hermann Strebel (1868-1943) was born in Munich where, after receiving his doctorate in medicine from Erlangen University in 1892 and for some years working in Regensburg, he practiced as a physician specializing in the then new field of light therapy, also holding some patents in that field. Presumably because of this specialization he also became interested in solar research, so in 1926 he began building an observatory in Herrsching near Munich. Unusually for the time, he used mirror telescopes, built by the famous B. Schmidt, for his solar observations. His best observations, resulting for example in the recognition of the polygonal structure of solar granules, were of an equal quality with the stratospheric observations made in the 1960s. However, Strebel also produced quite a weird theory of the sun's structure, ignoring the results of concurrent academic research. In 1932 Strebel bequeathed his observatory to the Munich-Bogenhausen observatory which was then still part of the Administration of Scientific Collections of the (Bavarian) State . In 1937 he stopped observing, and most of the instruments were brought to Bogenhausen where not much use was made of them, however. His publications of observations in the 1930s provoked renewed interest in solar granulation eg, by H. H. Plaskett , but then soon became forgotten. Yet, he was one of the most successful astronomical practitioners in Bavaria between the World Wars.

Extractions: Mathematician Report Index Below is a list of mathematicians. You may choose from this list or report on a mathematician not listed here. In either case, you must discuss with me the mathematician you have chosen prior to starting your report. No two students may write a report on the same mathematician. I would advise you to go to the library before choosing your topic as there might not be much information on the mathematician you have chosen. Also, you should determine the topic early in the term so that you can "lock-in" your report topic!! The report must include: 1. The name of the mathematician. 2. The years the mathematician was alive. 3. A biography. 4. The mathematician's major contribution(s) to mathematics and an explanation of the importance. 5. A historical perspective during the time the mathematician was alive.
