La historia de la ciencia en la Edad Media es, hasta el siglo X, la del mantenimiento precario de los escasos saberes de la Antigüedad clásica que habían sobrevivido en occidente. A partir de entonces, la traducción del árabe de las obras de autores griegos fue la tarea fundamental. En el siglo XIII aparecen los primeros matemáticos medievales realmente creadores - Fibonacci, Jordano Nemorario y Nicolás de Oresme, entre otros. Al estudio de la obra de estos científicos y la de sus precursores está dedicado este libro.
