Hello everyone,

I would like to point out a subject which attract my attention very much. It is the books before and after the painting press. Approximately 4.500 years ago printing press was invented by Gutenberg and before that all books were written by hand. After Gutenberg's this invention, this spreads very quickly with the techonological development. Thanks for the Gutenberg's invention, students could learn historical and cultural contents. I cannot think what we do without this invention! Here is a link about this issue:
