# Scientific Instrument **Domain:** Measurement / Epistemology / Technology **Doc Type:** Canonical Concept Node **Maturity:** Developed ## Definition A **scientific instrument** extends observation by producing measurements through a designed interaction among phenomenon, sensor, calibration and interpretation. ## Evolutionary Nexus Muybridge's cameras, mass spectrometers, genome browsers and DENDRAL all function as instruments in [[articles/The Evolutionary Roots of Silicon Valley|The Evolutionary Roots of Silicon Valley]]. Some detect signals; others organize evidence or generate hypotheses. ## Governance Context Instruments are theory-laden: calibration and representation determine what becomes visible. When an AI system functions as an instrument, its outputs require traceable inputs, validation and a distinction between measurement and interpretation. ## See Also [[wiki/Machine Vision|Machine Vision]], [[wiki/DENDRAL|DENDRAL]], [[wiki/UCSC Genome Browser|UCSC Genome Browser]], [[wiki/Provenance|Provenance]]
