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.

Fermi Estimates and Dyson Designs An Article by Venkatesh Rao www.ribbonfarm.com A Fermi estimate is a quick-and-dirty solution to an arbitrary scientific or engineering analysis problem. Fermi estimation uses widely known numbers, readily observable phenomenology, basic physics equations, and a bunch of approximation techniques to arrive at rough answers that tend to be correct within an order of magnitude or so. The term is named for Enrico Fermi, who was famously good at this sort of thing. …It struck me that there is counterpart to this kind of thinking on the synthesis side, where you use similar techniques to arrive at a very rough design for a complex engineered artifact. I call such a design approach Dyson design, after the physicist Freeman Dyson, who was one of the best practitioners of it (not to be confused with inventor James Dyson, whose designs, ironically, are not Dyson designs). designphysics
