The applied sciences put knowledge to work under real constraints. Engineering, computing, medicine, agriculture, and architecture turn models from the formal and natural sciences into designs, treatments, tools, and places that must be safe, reliable, and worth their cost. Mettica traces each application back to the principles it depends on and forward to the trade-offs it forces.

Disciplines
What Applied Sciences covers
5 disciplines. Each is listed under one subject for browsing, and many connect to others.
Engineering
Designing and building structures, machines, energy systems, and devices.
These concepts pass through applied sciences and continue into other fields.
Symmetry
Invariance under transformation: formalized as a group, tied to conservation laws, used in structural design and artistic composition, and debated as a question about sameness.
Outputs that loop back to change the system producing them: control in engineering, homeostasis in biology, self-reinforcing cycles in markets and societies, and stability in dynamical systems.
