the invention of the Gutenberg press changed communication in the western world
Johann Gutenberg’s invention of movable-type printing quickened the spread of knowledge, discoveries, and literacy in Renaissance Europe. The printing revolution also contributed mightily to the Protestant Reformation that split apart the Catholic Church.
The printing revolution also helped develop modern science in Europe. For example, in 1543, the Polish scholar, Copernicus, took advantage of printed works on astronomy and tables of data on planet movements to print his own book, arguing that the earth revolved around the sun. Later, the Danish astronomer, Tycho Brahe, installed a printing press and paper mill near his observatory in order to print books on his discoveries.
