outline goals status downloads ... references (skip to: human-readable source for message) Outline of CosmicOS It's a familiar problem. You've finally managed to contact that alien civilization. Things are going great. You feel like your world will never be the same, that whole new realms of possibilities are opening up before your eyes. Then, inevitably, a hint of strain starts to creep into your relationship. You find that you don't really have all that much in common. Heck, sometimes it feels like you're not even in the same galaxy. It's as if there is this vast gulf between you, making communication almost impossible. You're not even sure you'd understand each other no matter how physically close you become. What do you do? You design a language for cosmic intercourse. Hans Freudenthal made a start at one in his book, Lincos, published in 1960. I think it's time for version II, the all-new action-packed sequel guaranteed to have you on the edge of your seat, which is a specific structure with a flat surface perpendicular to the pull of gravity, which is a thing that, oh never mind. more...

25. Portret Van Hans Freudenthal Prof. Dr. hans freudenthal (1905 1990). hans freudenthal werd in 1905 geborente Luckenwalde in Duitsland als zoon van een Joodse leraar. http://www.fi.uu.nl/nl/freudenthal.html

Prof. Dr. Hans Freudenthal (1905 - 1990) Hans Freudenthal werd in 1905 geboren te Luckenwalde in Duitsland als zoon van een Joodse leraar. Van jongsaf aan werd hij gegrepen door wiskundige fenomenen als differentiaalvergelijkingen en integratie. Op dertienjarige leeftijd had hij alle werken van Goethe en Schiller gelezen. Vanaf 1923 studeerde hij wiskunde in Berlijn en Parijs. Na het behalen van zijn doctoraal examen verhuisde hij naar Amsterdam waar hij de beroemde wiskundige L.E.J. Brouwer in 1930 assisteerde. Kort daarna trouwde hij Suus Lutter, een pedagoge. Dankzij dit huwelijk (en een portie geluk), wist Freudenthal de Tweede Wereldoorlog te overleven. Vanaf 1946 bezette Freudenthal als professor de stoel 'theoretische en toegepaste wiskunde' in Utrecht. Hiermee vestigde hij zich definitief als bekend wiskundige, waarbij hij wezenlijke (wetenschappelijke) bijdragen leverde aan de topologie, geometrie en de 'theorie van Lie' groepen. Als onderwijzer verwierf hij internationale faam en erkenning als de oprichter van de toegepaste (realistische) wiskunde die gebaseerd is op alledaagse problemen in plaats van de (tot dan toe) gebruikelijke abstracte wiskunde. Door zijn invloed voorkwam Freudenthal dat het Nederlandse onderwijs de Amerikaanse 'New Math' methoden adopteerde - wat in veel andere landen wel gebeurde vanaf 1960. Deze formele methode, grotendeels gebaseerd op abstracte logica, bleek later ongeschikt voor de meerderheid van de studenten.

Wikimedia needs your help in its 21-day fund drive. See our fundraising page Over US$155,000 has been donated since the drive began on 19 August. Thank you for your generosity! Freudenthal suspension theorem From Wikipedia, the free encyclopedia. In mathematics , and specifically in the field of homotopy theory , the Freudenthal Suspension Theorem is the fundamental result leading to the concept of stabilization of homotopy groups and ultimately to stable homotopy theory . It explains the behavior of simultaneously taking suspensions and increasing the index of the homotopy groups of the space in question. It was proved in 1937 by Hans Freudenthal Contents Statement of the theorem Corollary 1 Corollary 2 Reference ... edit Statement of the theorem Let X be an n-connected pointed space (a pointed CW-complex or pointed simplicial set ). The map X → Ω(X ∧ S induces a map k (X) → π k (Ω(X ∧ S on homotopy groups, where denotes the loop functor and denotes the smash product . Then the induced map on homotopy groups is an isomorphism if k n and an epimorphism if k = 2 n Note that k (Ω(X ∧ S k+1 (X ∧ S so that the theorem could otherwise be stated in terms of the map k (X) → π k+1 (X ∧ S with the small caveat that in this case one must be careful with the indexing.

THE ICMI HANS FREUDENTHAL MEDAL FOR 2003 Citation for the 2003 ICMI Freudenthal Medal to Celia Hoyles Celia Hoyles The first Hans Freudenthal Medal of the International Commission on Mathematical Instruction (ICMI) is awarded to Professor Celia Hoyles. This distinction recognises the outstanding contribution that Celia Hoyles has made to research in the domain of technology and mathematics education, both in terms of theoretical advances and through the development and piloting of national and international projects in this field, aimed at improving through technology the mathematics education of the general population, from young children to adults in the workplace. Celia Hoyles studied mathematics at the University of Manchester, winning the Dalton prize for the best first-class degree in Mathematics. She began her career as a secondary teacher, and then became a lecturer at the Polytechnic of North London. She entered the field of mathematics education research, earning a Masters and Doctorate, and became Professor of Mathematics Education at the Institute of Education, University of London in 1984. Her early research in the area of technology and mathematics education, like that of many researchers, began by exploring the potential offered by Logo, and she soon became an international leader in this area. Two books published in 1986 and 1992 (edited) attested to the productivity of her research with Logo. This was followed, in 1996, by the publication of

The International Commission on Mathematical Instruction ICMI Bulletin No. 48 June 2000 ICMI Executive Committees 1908-1998 During the fourth International Congress of Mathematicians, held in Rome in 1908, the following resolution was adopted: "The Congress, recognizing the importance of a comparative study on the methods and plans of teaching mathematics at secondary schools, charges Professors F. Klein, G. Greenhill, and Henri Fehr to constitute an International Commission to study these questions and to present a report to the next Congress." This resolution was submitted on the initiative of David Eugene Smith, who had suggested the idea of such an international commission three years earlier in the journal L'Enseignement Mathématique, in response to an article by Fehr. It marks the inception of the International Commission on Mathematical Instruction - although the Commission was known in its earlier years as the "International Commission on the Teaching of Mathematics". Over the years various Executives Committees of the Commission (first known as "Central Committees") have succeeded one another. The list of their officers and members appears below. This information has been gathered from the following sources: Georges de Rham, "L'Enseignement Mathématique - Revue internationale et la Commission internationale de l'enseignement mathématique (CIEM) - Notice historique", ICMI Bulletin 7 (1976) 29-34.

Return to The Worlds of David Darling INDEX LATEST NEWS ARCHIVE ... Z entire Web this site LINCOS "Lingua Cosmica. A language for extraterrestrial communication developed by Hans Freudenthal, Professor of Mathematics at the University of Utrecht. Details of it are presented in Freudenthal's book published in the Netherlands in 1960. LINCOS represents an extension of the logistic language of mathematics developed by Alfred North Whitehead and Bertrand Russell. It is intended to be conveyed by unmodulated radio signals of varying duration and wavelength which represent phonemes. The signals would be combined to make up concepts or words. Lancelot Hogben, who himself described a code for communication with alien intelligence, called Astraglossa , discussed Freudenthal's work. See also mathematics, as a universal language References 1.
