"…it is useful for a biologist to think about chemical processes, and for a chemist to think about interactions at the level of physics, and for a physicist to do math. The #membrane & the #handle are essential, but sometimes you have to decap the sealed package and inspect and manipulate its internals directly. #Problemsolving, #improvement and #maintenance all require the ability to move up and down the stack of abstractions to figure out where to stick your probes and stage your interventions." @pluralistic@mamot.fr https://pluralistic.net/2026/07/03/rod-logic/
