Applied Sciences & Engineering¶

← Back to Abstractions 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?"

186 primes · 2,175 domain-specific abstractions across 14 domains in this group. Both layers draw on the same canonical roster; a domain's group is derived from it, never stored on an entity.
