Editor's Notes
- #3: Engineering is also the application to: equip creative minds with the mathematical and analytical skills necessary to conceive of new designs intelligently question present ways of accomplishing tasks find better alternative methods in light of evolving technology
- #6: Also mention: Can be disheartening - much of the work is trial and error Last few decades, almost all research was done solo With knowledge of chemistry, physics, and biology, groups or “research teams” of scientists and engineers would accelerate discoveries
- #7: Involved in the acquisition of patents to protect ideas, processes or products Creativity and innovation, a knowledge of basic principles of science and an inherent cleverness in making things work The actual construction, fabrication, assembly, layout, and testing of scale models, pilot models, and experimental models for pilot processes or procedures that will work Does not deal exclusively with new discoveries but involves using well-known principles and employing existing processes or machines to perform a new or unusual function Searches in library, manufacturing literature and patents for existing ideas Involved in the acquisition of patents to protect ideas, processes or products Creativity and innovation, a knowledge of basic principles of science and an inherent cleverness in making things work
- #8: Not only must the device or process work, it must also be made in a style and at a price that will attract customers. To arrive at a design solution that will provide for adequate safety without excessive redundancy
