"La ciencia avanza, proyectando hacia adelante su luz...". La prensa científica en la Ciudad de México a finales del siglo XIX (1890-1899).

The Porfiriato was a time of transcendent changes in the history of Mexican journalism. One of them was the consolidation of the scientific press in the last decade of the 19th century, particularly in Mexico City. This text aims to explain the causes that originated this phenomenon from three axes: positivism, scientific societies and the means of communication and transport. [ABSTRACT FROM AUTHOR]
