Applied Sciences & Engineering¶
← Back to Mechanisms by Domain Group
Scientific and mathematical knowledge applied to the design, construction, and operation of artefacts and systems. Animating question: "given what the natural sciences tell us, how do we build things that work?"
2,805 mechanisms across 14 domains in this group. Mechanisms draw on the same canonical roster the two abstraction layers do; a domain's group is derived from it, never stored on an entity. Counted by primary origin domain — a mechanism that also draws on other domains is listed once, here.
