What is Engineering?



Application of:Math -

Science -Technical -Principles

to Create tangible, practical solutions

Problem Solving

Theory in Practice

Knowledge in Action

Manufacturing

Designing Solutions

Manifesting Ideas


Science vs. Engineering

Science:1. Systematically obtaining knowledge by observation and

experience2. Use the Scientific Method3. Empirical / Objective

Engineering:4. Application of math and science by which matter and

energy are made useful to people5. Designing and implementing solutions that fulfill an

objective, need, or desire – based on knowledge6. Subjective solutions based on objective knowledge


“Engineering. . .to define rudely but not inaptly is the art of doing that well with one dollar, which any bungler can do with two

after a fashion.” – Arthur Mellen Wellington,

The Economic Theory of Railway Location (1911)

Major Fields:

1. Aerospace - This field of engineering deals with design, production and operation of various aircrafts, spacecrafts, missiles and other airborne technologies. This field is an expansion of another branch of engineering termed as the Aeronautical engineering, which deals exclusively with aircrafts.



Major Fields:

2. Bioengineering – the application of engineering principles to address challenges in the fields of biology and medicine. Biological engineering applies principles to the full spectrum of living systems, including molecular biology, biochemistry, microbiology, pharmacology, protein chemistry, cytology, immunology, neurobiology and neuroscience.

Major Fields:

3. Chemical – largely involves the design, improvement and maintenance of processes involving chemical or biological transformations for large-scale manufacture. Chemical engineers ensure the processes are operated safely, sustainably and economically.




Major Fields:4. Civil – deals with the design, construction and

maintenance of the physical and naturally built environment, including works such as bridges, roads, canals, dams and buildings.

• Civil engineering is the oldest engineering discipline after military engineering.

• It includes environmental engineering, geotechnical engineering, structural engineering, transportation engineering, municipal or urban engineering, water resources engineering, materials engineering, coastal engineering, surveying, and construction engineering.




Major Fields:

5. Computer Engineering – electronic engineering, software design and hardware-software integration instead of only software engineering or electronic engineering.

6. Computer Science – is the study of the theoretical foundations of information and computation, and of practical techniques for their implementation and application in computer systems.



Fields of EngineeringMajor Fields:

7. Electrical – considered to deal with the problems associated with large-scale electrical systems such as power transmission and motor control. Deals with the study and application of electricity, electronics, and electromagnetism.

8. Electronic – deals with the study of small-scale electronic systems including computers and integrated circuits.

Electrical engineers are usually concerned with using electricity to transmit energy, while electronic engineers are concerned with using electricity to transmit information.




9. Material – Deals with the fundamental properties and characteristics of materials. Investigates and utilizes the relationship between the structure of materials at atomic or molecular scales and their macroscopic properties. It includes elements of applied physics and chemistry. It includes the fields of nanoscience and nanotechnology.




10. Mechanical – was developed from the application of principles from physics and materials science. It involves

the analysis, design, manufacturing, and maintenance of various mechanical (or moving) systems. It is one of the oldest and broadest engineering disciplines. ME’s design and analyze manufacturing plants, industrial equipment and machinery, heating and cooling systems, motor vehicles, aircraft, watercraft, robotics, nanorobotics, medical devices and more.




11. Nuclear – the application of the breakdown of atomic nuclei and/or other sub-atomic physics, based on the principles of nuclear physics. It includes, but is not limited to, the interaction and maintenance of nuclear fission systems and components— specifically, nuclear reactors, nuclear power plants, and/or nuclear weapons.





Major Fields:

12. Process Engineering – focuses on the design, operation and maintenance of chemical and other process manufacturing activities. Process engineering is often a synonym for chemical engineering but process engineers are found in a vast range of industries, such as the petrochemical, mineral processing, material, information technology, food and pharmaceutical and biotechnological industries. Process engineering also involves developing new processes, project engineering and troubleshooting.
