El diablo de los nmeros,Used
Delivery time: 8-12 business days (International)
A Robert no le gustan las Matemticas, como sucede a muchas personas, porque no las acaba de entender. Pero una noche l suea con un diablillo que pretende iniciarle en la ciencia de los nmeros. Naturalmente, Robert piensa que es otra de sus frecuentes pesadillas, pero en realidad es el comienzo de un recorrido nuevo y apasionante a travs del mundo de las Matemticas. No es extrao hallar siempre secuencias numricas por la simple multiplicacin de los unos: 1 x 1 = 1, 11 x 11 = 121, 111111 x 111111 = 12345654321, y as en adelante? Y esto es slo la operacin ms sencilla. Durante doce noches, Robert suea sistemas numricos cada vez ms increbles. De pronto, los nmeros cobran vida por s mismos, una vida misteriosa que ni siquiera el diablo puede explicar del todo. Nunca las Matemticas haban sido algo tan fascinante. Pronto, el diablo le har abandonar los tpicos escolares y har que acceda a niveles superiores: y aun as los entiende! Y el joven lector tambin. Los nmeros, cada pgina que pasa, se van volviendo cada vez ms absorbentes. Es como magia, y Robert quiere saber ms y ms hasta que, al fin, el diablo le hace comprender que algunos problemas y paradojas pertenecen a las altas esferas de la ciencia.
