One can now picture a future investigator in his laboratory. His hands are free, and he is not anchored. As he moves about and observes, he photographs and comments. Time is automatically recorded to tie the two records together. If he goes into the field, he may be connected by radio to his recorder. As he ponders over his notes in the evening, he again talks his comments into the record. His typed record, as well as his photographs, may both be in miniature, so that he projects them for examination.
This is one of the most important aspects of the essay. Noting that he is continuously talking about the work of a scientist, he stresses the act of recording, of looking at reality. This is radically different from what Ahrens claims in his book "How to take Smart Notes", in which there is not a single hint to the fact that you must look through the window and not just into previous works.
