问题    Engineering is the professional art of applying science to the optimum conversion of the re- sources of nature to the uses of humankind. Engineering has been defined as the creative application of "scientific principles to design or develop structures, machines, apparatus, or manufacturing processes, or works utilizing them singly or in combination." The term engineering is sometimes more loosely defined, especially in Great Britain, as the manufacture or assembly of engines, ma- chine tools, and machine parts.
   Associated with engineering is a great body of special knowledge; preparation for professional practice involves extensive training in the application of that knowledge. The function of the scientist is to know, while that of the engineer is to do. The scientist adds to the store of verified, systematized knowledge of the physical world; the engineer brings this knowledge to bear on practical problems. Engineering is based principally on physics, chemistry, and mathematics and their extensions into materials science, solid and fluid mechanics, thermodynamics, and systems analysis.
选项
答案 工程学是一门专业艺术，它通过科学把自然资源经过最适当的转化来满足人类的需要。 工程学被定义为富有创造性的应用科学，它把科学原理用于设计或创造结构、机械、器械或制造程序或操作，它要么单独使用它们，要么结合起来使用。有时工程学的定义很宽泛，尤其是在英国，工程学被看作加工业或是发动机、机器工具和机器零件的装配。 与工程学相关的是庞大的专业知识；通过广泛的训练来加强那些知识的应用是专业操作的准备工作。科学家的作用是去了解，而工程师的作用是去实施。科学家们给知识储备增添确凿的、系统的物质世界知识；而工程师则用这些知识去解决实际的问题。工程学主要建立在物理学、化学和数学以及这些学科的延伸材料科学、固体和液体力学、热力学及系统分析的基础上的。
