engineering
the discipline that applies scientific knowledge to design, build, and maintain structures, machines, and systems. engineering bridges tech (tools and construction), chemo (materials), and energo (energy conversion)
in the crystal, engineering spans three domains:
tech — architecture, building, construction, infrastructure, robot, 3d printing
chemo — metal, glass, bioplastic, cellulose, materials science
energo — battery, engine, photovoltaic panel, wind turbine, heat pump
branches
civil engineering → tech + geo (building, road, foundation of buildings, roman concrete)
mechanical engineering → tech + energo (engine, lever, wheel, stirling engine)
electrical engineering → tech + quantum (semiconductor, circuits, antenna, inverter)
chemical engineering → tech + chemo (process design, polymerization, fermentation)
software engineering → tech + comp (operating systems, compilers, distributed systems)
biomedical engineering → tech + bio (prosthetics, imaging, drug delivery)
