Be A (Re)Visitor An Article by Rob Walker robwalker.substack.com I was thinking about this not long ago while reading in Petapixel an essay by a photographer named Scott Reither, “Long Form Study: Why Photographers Should Repeatedly Revisit A Scene.” In it, he described photographing one particular stretch of beach, over and over, throughout his career. Of course that landscape has changed over time, and of course he’s had moments when he felt he’d captured the same territory so many times there was nothing left to see. But there was always something more to see — maybe because of a change in Reither’s life, rather than in the physical environment. seeingchangephotography
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
