A three-layered process of documentation A three-layered process of documentation: (1) First, there is the field notebook. This is where the actual numbers are recorded, together with passing observations relevant to the interpretation of these numbers. Paper is still proving more durable than electronic data. (2) The journal is a parallel record to that of the notebook—a daily account of events, thoughts, and observations. (3) Last of the three strata, then, are the publications. Traditionally, in science, these are articles in academic journals leavened with chapters in books. To be successful, a young scientist need aspire to no more than these two forms of output together with their oral versions at interminable conferences and meetings of learned societies. There came a time in my scientific development, however, when other forms of publication became important: magazines articles, and writing books.

The requirements of economy Economy is the mother of most inventions, not necessity, unless in the sense of poverty and hardship. A requirement for convenience is simply a diluted requirement for ease and economy. It seems to be invariably true that those characteristics which lead people to call a design functional are derived from the requirements of economy and not of use.
