Architecture
Architecture is both the process and the product of planning, designing, and constructing buildings or any other structures. Architectural works, in the material form of buildings, are often perceived as cultural symbols and as works of art. Historical civilizations are often identified with their surviving architectural achievements.
Naval Architecture
Naval architecture, or naval engineering, along with automotive engineering and aerospace engineering, is an engineering discipline branch of vehicle engineering, incorporating elements of mechanical, electrical, electronic, software and safety engineering as applied to the engineering design process, shipbuilding, maintenance, and operation of marine vessels and structures. Naval architecture involves basic and applied research, design, development, design evaluation and calculations during all stages of the life of a marine vehicle. Preliminary design of the vessel, its detailed design, construction, trials, operation and maintenance, launching and dry-docking are the main activities involved. Ship design calculations are also required for ships being modified (by means of conversion, rebuilding, modernization, or repair). Naval architecture also involves formulation of safety regulations and damage-control rules and the approval and certification of ship designs to meet statutory and non-statutory requirements.
Architecture
Architecture differs from a work of art, which can be displayed in different settings and the subject-matter, form and meaning will remain unchanged. The physicality of any built structure can be altered over time as additions and alterations are made. Moreover, a building or work of architecture can change its function as it meets the different demands of its occupants, although its exterior appearance may be unaltered. And its meaning may change depending on the nature of the context. This reveals some of the problems of interpreting historic architecture from a modern-day perspective as the physical changes and different cultural contexts transform the object.
