Field notes
Short essays from the workbench: what our models simplify, what an object reveals when examined closely, and why a design decision can change the meaning of evidence.
Current issue
Three ways to look past the finished surface.
Read note
How to read a woodblock print as a sequence
The finished sheet hides a collaboration among publisher, designer, carver and printer, plus a careful chain of blocks, registration and pressure.
Scale is an editorial decision
A truthful map can still distort size, distance or time. The important question is which distortion is declared, controlled and useful.
How we write
Begin with the source. Separate observation from inference.
Field notes cite primary or institutional references where a factual claim depends on them. Product-specific reconstruction and simulation boundaries are stated directly. Corrections are treated as part of publishing, not as a failure of the format.
