What is the difference between science and engineering?

Answer 1

Engineering is applied science.

In a nutshell, scientists figure out how things work, engineers find practical uses for that research.

Answer 2

Science is the entire realm of figuring out the natural world. Engineering is using science to create things that are useful to mankind.

Answer 3

science is basicly a theoreticial realm, where as engineering technology, is taking these scientific ideas, to make a useful product. there have been very few true scientist, since most of what people mislabel as scientist, are actualy technologists. such as most people, think of thomas edision as a scientist. but in reality he was a technologist, using known scientific principals.

Answer 4

Scientists figure out how things work. Engineers use that knowledge to do stuff. Really great inventors are both scientist and enginner.

Answer 5

i myself am a metallurgical engineer . in my opinio engineering is the use(application) of science in nature or it is better to say to adopt science with activity.

Answer 6

If you are a scientist, your lab is sheltered in some university lab.

If you are an engineer, your lab is mankind and his REAL environment.

Science
Science in the broadest sense refers to any system of knowledge attained by verifiable means.[1] In a more restricted sense, science refers to a system of acquiring knowledge based on empiricism, experimentation, and methodological naturalism, as well as to the organized body of knowledge humans have gained by such research. This article focuses on the meaning of science in the latter sense.

Scientists maintain that scientific investigation must adhere to the scientific method, a process for evaluating empirical knowledge that explains observable events in nature as results of natural causes, rejecting supernatural notions.

Fields of science are commonly classified along two major lines:
* Natural sciences, the study of the natural phenomena;
* Social sciences, the systematic study of human behavior and societies.

Mathematics has both similarities and differences compared to other fields of science. It is similar to other sciences, because it is a rigorous, structured study of topics such as quantity, structure, space, and change. It is, however, different in its method of arriving at results. Mathematics as a whole is vital to the sciences — indeed, major advances in mathematics have often led to major advances in other sciences. Certain aspects of mathematics are indispensable for the formation of hypotheses, theories, and laws, both in discovering and describing how things work (natural sciences) and how people think and act (social sciences).

Science as defined above is sometimes termed pure science in order to differentiate it from applied science, the latter being the application of scientific research to human needs.

Engineering
Engineering is the application of scientific and mathematical principles to develop economical solutions to technical problems, creating products, facilities, and structures that are useful to people.[1][2] Engineers use imagination, judgment, and reasoning to apply science, technology, mathematics, and practical experience. The result is the design, production, and operation of useful objects or processes.

Methodology
The crucial and unique task of the engineer is to identify, understand, and integrate the constraints on a design in order to produce a successful result. It is usually not enough to build a technically successful product; it must also meet further requirements. Constraints may include available resources, physical or technical limitations, flexibility for future modifications and additions, and other factors, such as requirements for cost, marketability, producibility, and serviceability. By understanding the constraints, engineers derive specifications for the limits within which a viable object or system may be produced and operated.

Problem solving
Engineers use their knowledge of science, mathematics, and appropriate experience to find suitable solutions to a problem. Creating an appropriate mathematical model of a problem allows them to analyze it (sometimes definitively), and to test potential solutions. Usually multiple reasonable solutions exist, so engineers must evaluate the different design choices on their merits and choose the solution that best meets their requirements. Genrich Altshuller, after gathering statistics on a large number of patents, suggested that compromises are at the heart of "low-level" engineering designs, while at a higher level the best design is one which eliminates the core contradiction causing the problem.

Engineers typically attempt to predict how well their designs will perform to their specifications prior to full-scale production. They use, among other things: prototypes, scale models, simulations, destructive tests, nondestructive tests, and stress tests. Testing ensures that products will perform as expected. Engineers as professionals take seriously their responsibility to produce designs that will perform as expected and will not cause unintended harm to the public at large. Engineers typically include a factor of safety in their designs to reduce the risk of unexpected failure. However, the greater the safety factor, the less efficient the design may be.

Computer use
As with all modern scientific and technological endeavours, computers and software play an increasingly important role. Numerical methods and simulations can help predict design performance more accurately than previous approximations.

Using computer-aided design (CAD) software, engineers are able to more easily create drawings and models of their designs. Computer models of designs can be checked for flaws without having to make expensive and time-consuming prototypes. The computer can automatically translate some models to instructions suitable for automatic machinery (e.g., CNC) to fabricate (part of) a design. The computer also allows increased reuse of previously developed designs, by presenting an engineer with a library of predefined parts ready to be used in designs. Computers can also be used as part of the manufacturing process, controlling the machines and ensuring a constant level of quality and similarity in the products. This process is Computer Aided Manufacture (CAM) and works in a similar way to CNC but where CNC controls the machinery, CAM controls the whole manufacture process from cutting to assembly.

Of late, the use of finite element method analysis (FEM analysis or FEA) software to study stress, temperature, flow as well as electromagnetic fields has gained importance. In addition, a variety of software is available to analyse dynamic systems.

Electronics engineers make use of a variety of circuit schematics software to aid in the creation of circuit designs that perform an electronic task when used for a printed circuit board (PCB) or a computer chip.

The application of computers in the area of engineering of goods is known as Product Lifecycle Management (PLM).
