Der Satz des Pythagoras: a²+b²=c² steht im Zentrum des Rätsels, um das es hier geht. Diese »Urformel« gilt immer und überall, aber nur in der Zweier-Potenz, mit keiner anderen ganzen Zahl. In den Notizen des französischen Mathematikers Pierre Fermat, der im 17. Jahrhundert lebte, gibt es einen Hinweis, daß er den Beweis für dieses Phänomen gefunden hat. Doch der Beweis selbst ist verschollen. 350 Jahre lang versuchten nun die Mathematiker der...

Fin dall'antichità l'uomo ha pensato di creare codici segreti, sistemi di segni capaci di nascondere a occhi indiscreti un importante messaggio e rivelarlo solo ai destinatari. Al mondo misterioso dei codici è dedicato il libro di Simon Singh, che racconta con passione una serie di storie esemplari: quella di Maria Stuarda e del codice segreto che la condusse al patibolo, la macchina Enigma, usata dai tedeschi durante la seconda guerra mondial...

In his first book since the bestselling Fermat's Enigma, Simon Singh offers the first sweeping history of encryption, tracing its evolution and revealing the dramatic effects codes have had on wars, nations, and individual lives.

xn + yn = zn, where n represents 3, 4, 5, ...no solution"I have discovered a truly marvelous demonstration of this proposition which this margin is too narrow to contain."With these words, the seventeenth-century French mathematician Pierre de Fermat threw down the gauntlet to future generations. What came to be known as Fermat's Last Theorem looked simple, proving it, however, became the Holy Grail of mathematics, baffling its finest minds fo...

Simon Singh, author of the bestsellers Fermat's Enigma, The Code Book, and Big Bang, offers fascinating new insights into the celebrated television series The Simpsons: That the show drip-feeds morsels of number theory into the minds of its viewers-indeed, that there are so many mathematical references in the show, and in its sister program, Futurama, that they could form the basis of an entire university course.Recounting memorable episodes f...

You may have watched hundreds of episodes of The Simpsons (and its sister show Futurama) without ever realizing that cleverly embedded in many plots are subtle references to mathematics, ranging from well-known equations to cutting-edge theorems and conjectures. That they exist, Simon Singh reveals, underscores the brilliance of the shows' writers, many of whom have advanced degrees in mathematics in addition to their unparalleled sense of hum...
