    <title>Poincare und Perelman</title>
    <link>http://math.twoday.net/stories/2604852/</link>
    <description>&lt;p&gt;Sylvia Nasar und David Gruber schreiben im &lt;i&gt;The New Yorker&lt;/i&gt; über die &lt;a href=&quot;http://www.newyorker.com/printables/fact/060828fa_fact2&quot; target=&quot;_blank&quot;&gt;Vermutung von Poincare und Grigory Perelman&lt;/a&gt;:&lt;br /&gt;
Grigory Perelman did not plan to become a mathematician. There was never a decision point, he said when we met. We were outside the apartment building where he lives, in Kupchino, a neighborhood of drab high-rises. Perelmans father, who was an electrical engineer, encouraged his interest in math. He gave me logical and other math problems to think about, Perelman said. He got a lot of books for me to read.&lt;br /&gt;
Hier ist das Titelblatt des Buchs &lt;i&gt;Unterhaltsame Algebra&lt;/i&gt; aus dem Jahre 1967, geschrieben von Perelmans Vater: &lt;/p&gt; 
&lt;img width=&quot;248&quot; height=&quot;400&quot; title=&quot;Titelblatt eines Buchs Unterhaltsame Algebra&quot; src=&quot;http://static.twoday.net/math/images/Perelman.jpg&quot; alt=&quot;Titelblatt eines Buchs Unterhaltsame Algebra&quot; /&gt;
&lt;p&gt;[Korrektur 7.9.06]: Perelman hat zwar Perelmans Buch &lt;i&gt;Unterhaltsame Algebra&lt;/i&gt; gekannt, aber der Autor war mitnichten sein Vater (siehe Kommentare).&lt;/p&gt;</description>

    <title>&lt;p&gt;Is Math a Sport?&lt;/p&gt;</title>
    <link>http://math.twoday.net/stories/279591/</link>
    <description>&lt;blockquote&gt;The philosopher Bernard Suits defines a sport as a game that meets the following four criteria: &quot;(1) that the game be a game of skill; (2) that the skill be physical; (3) that the game have a wide following; and (4) that the following achieve a certain level of stability.&quot;&lt;br /&gt;
&lt;br /&gt;
The first condition excludes Russian roulette; the second eliminates math, chess, spelling, and bridge; the third and fourth conditions, alas, rule out urinating for distance. Suits&apos; definition is compelling, but difficulties hide not far below the surface.&lt;br&gt;

    <title>New New Math</title>
    <link>http://math.twoday.net/stories/34889/</link>
    <description>Ein schon ältere Debatte (ca. 5 Jahre?) in den USA dreht sich um die sogenannte &quot;New New Math&quot;, bei der Kindern Mathematik beigebracht werden soll, ohne das es auf Exaktheit ankommt. Zwei Artikel dazu:&lt;br /&gt;
&lt;br /&gt;
