Where did the Gutenberg discontinuity get its name from?

The Gutenberg discontinuity is named after Johannes Gutenberg, the inventor of the movable-type printing press in the 15th century. This geological boundary marks the transition between the Earth's crust and the underlying mantle, which is analogous to Gutenberg's transformative impact on communication and knowledge dissemination. The term reflects the significant shift in properties and composition, similar to the revolutionary change in information access brought about by Gutenberg's invention.
