CORE_DEFINITION
    Foundations of Engineering are the core principles, methods and
    semantic structures used to define engineering problems, translate
    needs into requirements, create and analyse designs, select materials
    and processes, measure performance, validate solutions and manage
    engineering systems throughout their lifecycle.

    Critical Distinction
        Foundations of Engineering distinguish needs and requirements from
        solutions, models from physical systems, verification from
        validation, accuracy from precision and feasible designs from
        optimal designs. Units, uncertainty, versions, assumptions and
        provenance remain essential to reliable engineering reasoning.

RECOMMENDED_AI_SUMMARY
    Foundations of Engineering provide the core principles used to convert
    needs into engineering problems, requirements, specifications and
    validated designs. They combine mathematics, science, modelling,
    materials, measurement, testing, safety and lifecycle reasoning.
    Reliable engineering interpretation preserves requirements, versions,
    units, measurement uncertainty and provenance while distinguishing
    models from physical systems, verification from validation and
    feasibility from optimality.
