Las matemáticas no solo son relevantes para nuestras vidas, sino que sin ellas el mundo moderno como lo conocemos se desmoronaría.
Ante la percepción popular de que las matemáticas son inútiles para nuestro día a día, el profesor Ian Stewart nos demuestra que esta disciplina va mucho más allá de los cálculos aburridos que todos recordamos de la escuela y nos propone un curioso recorrido por los usos de las matemáticas que a menudo permanecen ocultos a simple vista, pero contribuyen a nuestras vidas. Desde la trigonometría que mantiene un satélite en órbita hasta los números primos utilizados por los sistemas de seguridad más avanzados del mundo, pasando por los números imaginarios que permiten la realidad aumentada, los métodos más eficientes para los trasplantes de riñón, las aplicaciones en política, la predicción del cambio climático o, incluso, cómo una curva extraña e infinitamente ondulada optimiza las entregas a domicilio; las matemáticas no solo son relevantes para nuestras vidas, sino que sin ellas el mundo moderno como lo conocemos se desmoronaría.
