Here In Europe we have a long tradition of storing learned information outside the brain. Of course elsewhere clever humans did the same tric. Here in my room I do use old and new methods of enlarging the network of information. When I studies, the library was a holy place with books. The information network was not great and not very friendly. When I wanted to read a book I had to ask a librarian to fetch it. Now my network is greater and I do seldom need to ask for somebody’s help. Now I have access to large encyclopedia’s like Wikipedia, vocabularies, help forums, almost direct access to colleagues on social media, newspapers, and manuals.
