👉 Engineering, particularly in the context of "by engineering," refers to the systematic application of scientific principles and methods to design, build, and optimize systems, structures, and processes to solve complex problems or meet specific needs. This approach emphasizes a structured, iterative process involving research, design, testing, and refinement to ensure that the final product or solution is safe, efficient, and effective. By engineering, professionals leverage interdisciplinary knowledge, including mathematics, physics, materials science, and computer science, to innovate and improve various aspects of technology, infrastructure, and everyday life, often prioritizing sustainability and societal impact.
