Physicist and science writer Bruce Schechter's biography of legendary Hungarian mathematician Paul Erdös is an engaging portrait, warm and intimate, bringing this strange, happy man to life. Schechter's focus is tighter and more traditionally biographical than Paul Hoffman's in The Man Who Loved Only Numbers. Here we get to see Erdös's brief childhood transform quickly into a carefree adolescence of solving difficult maths problems with his circle of brilliant friends--uniquely encouraged by a country that valued the contributions of mathematics in a way that has never been equalled. Fleeing the Holocaust, Erdös never settled down, instead travelling from place to place, showing up on the doorsteps of other mathematicians with his few possessions and an open mind. During his career, Erdös published more papers than any other mathematician in history. Most of the papers were collaborations:

For Erdös, the mathematics that consumed most of his waking hours was not a solitary pursuit but a social activity. One of the great mathematical discoveries of the twentieth century was the simple equation that two heads are better than one.... That radical transformation of how mathematics is created is the result of many factors, not the least of which was the infectious example set by Erdös.

Schechter spoke with many of Erdös's collaborators to complete this biography, which reveals the odd mathematician as charming, opinionated and completely dependent upon the kindness of others. Schechter not only tells his fascinating story, but introduces some intriguing mathematics problems (with easy-to-understand explanations) to show readers why Erdös loved the elegance of numbers more than anything else in the world. --Therese Littleton -- Dieser Text bezieht sich auf eine vergriffene oder nicht verf�gbare Ausgabe dieses Titels.

Physicist and science writer Bruce Schechter's biography of legendary Hungarian mathematician Paul Erdös is an engaging portrait, warm and intimate, bringing this strange, happy man to life. Schechter's focus is quite a bit tighter, and more traditionally biographical, than Paul Hoffman's in The Man Who Loved Only Numbers. Here, we get to see Erdös's brief childhood transform quickly into a carefree adolescence of solving difficult math problems with his circle of brilliant friends--uniquely encouraged by a country that valued the contributions of mathematics in a way that has never been equaled.

A readable account of the life of a mathematical genius. 1. Juni 1999

Von Ein Kunde

Format:Gebundene Ausgabe

I read _My Brain is Open_ right after finishing another biography of Erdos, _The Man Who Loved Only Numbers_. Although MBIO used many of the same anecdotes, it did different mathematics, sometimes only tangentially related to Erdos's work. Despite reading the two books so close together, I enjoyed both of them and the slightly different perspectives they presented of Erdos's life.

Lebensweg von Erdös 9. April 2009

Von Sessellehner

Format:Taschenbuch

Das Buch schildert den Lebensweg von Paul Erdös in chronologischer Reihenfolge. Es wird auf die besondere Situation Ungarns eingegangen, das schulische und persönliche Umfeld von Erdös wird beleuchtet. Manche seiner Eigenheiten erscheinen dadurch in einem anderen Licht. Weitere Stationen und mathematische Interessen werden spannend geschildert. Einige mathematische Themen werden durch Bilder gut veranschaulicht.
In der Regel geht die fachliche Darstellung nicht in die Tiefe, das muss aber auch nicht sein.
Insgesamt für einen mathematisch interessierten Leser eine sehr empfehlenswerte Lektüre über einen sehr außergewöhnlichen Menschen.

Monty Hall problem 4. Juni 2000

Von Stanislaw Tarka

Melbourne June 4, 2000

"Monty Hall problem"

Dear Mr. Schechter

I perhaps misunderstood your rules presented in "The Monty Hall " game but I think that answers recommending switching and examples you have provided are incorrect. Firstly I agree that initial probability of selecting a main Prize is 1/3. After one of the door revealing a goat is open I'm allowed to make a second guess. My chances of winning do increase, but if my choice is random, then I may select the same door. So there is only 50% chance that I will switch. Automatic switching may even reduce your chances of winning if my selection was correct in the first place. This is of course in case when chance of opening remaining two doors is purely random. I do not understand what do you mean when you say that: "..Monty can still show a goat, no matter which door your originally chose. " If you mean that result can be changed in a non-random way then rules of statistic do not apply. But assuming that they do, the strategy of making a second guess would work only if this game is played a large number of times. For a small number of trials probability laws do not apply. Instead we have case of simple gambling. So,this problem is not as simple as presented. No wander then even matematicians ,even Erdos himself had a trouble with accepting this solution!

Best Regards
