In France, in 1818, a nine-year-old boy accidentally blinded himself with a hole puncher while helping his father make horse harnesses. A few years later the boy was sitting in the yard thinking about his inability to read and write when a friend handed him a pinecone. He ran his fingers over the cone and noted the tiny differences between the scales. He conceptually blended the feel of different pinecone scales with reading and writing, and realized he could create an alphabet of raised dots on paper so the blind could feel and read what was written with it. In this way Louis Braille opened up a whole new world for the blind. Braille made a creative connection between a pinecone and reading. When you make a connection between two unrelated subjects, your imagination will leap to fill the gaps and form a whole in order to make sense of it. It is this willingness to use your imagination to fill in the gaps that produces the unpredictable idea. This is why Einstein claimed that imagination is more important than knowledge.
