Electrical and electronics engineering both focus on applications of electrical power. The two fields differ in that electrical engineers chiefly focus on the large-scale production and supply of electrical power, while electronics engineers focus on much smaller electronic circuits, such as those used in computers.

This is another broad area, but types of engineering management that you may like to specialize in include: engineering mathematics, management science, operations management, decision engineering, business statistics and engineering statistics. You can read more here.

Distortion is caused because the transverse magnification may be a function of the off-axis image distance. Distortion is classified as positive (so-called pincushion distortion), or negative (so-called barrel distortion). Field curvature (a.k.a. Petzval field curvature) results because the focal plane is actually not planar, but spherical. Spherical aberration occurs in a spherical lens or mirror because these do not focus parallel rays to a point, but instead along a line. Therefore, off-axis rays are brought to a focus closer to the lens or mirror than are on-axis rays.

This type of engineering concerns the use of chemical and biological processes to produce useful materials or substances. It’s a multidisciplinary subject, combining natural and experimental sciences (such as chemistry and physics), along with life sciences (such as biology, microbiology and biochemistry), plus mathematics and economics.

Common specializations of civil engineering include structural engineering, architectural engineering, transportation engineering, geotechnical engineering, environmental engineering and hydraulic engineering. You can read more about these here.

Astigmatism occurs in lenses because a lens has different focal lengths for rays of different orientations, resulting in a distortion of the image. In particular, rays of light from horizontal and vertical lines in a plane on the object are not focused to the same plane on the edges of the image. Chromatic aberration occurs in lenses because lenses bring different colors of light to a focus at different points. Coma occurs because off-axis rays no not quite converge at the focal plane. Coma is positive when off-axis rays focus furthest from the axis, and negative when they are closest. Distortion is caused because the transverse magnification may be a function of the off-axis image distance. Distortion is classified as positive (so-called pincushion distortion), or negative (so-called barrel distortion). Field curvature (a.k.a.

An optical aberration is a distortion in the image formed by an optical system compared to the original. They can arise for a number of reasons having to due with the limitations of optical components such as lenses and mirrors. Astigmatism occurs in lenses because a lens has different focal lengths for rays of different orientations, resulting in a distortion of the image. In particular, rays of light from horizontal and vertical lines in a plane on the object are not focused to the same plane on the edges of the image. Chromatic aberration occurs in lenses because lenses bring different colors of light to a focus at different points. Coma occurs because off-axis rays no not quite converge at the focal plane. Coma is positive when off-axis rays focus furthest from the axis, and negative when they are closest. Distortion is caused because the transverse magnification may be a function of the off-axis image distance. Distortion is classified as positive (so-called pincushion distortion), or negative (so-called barrel distortion). Field curvature (a.k.a. Petzval field curvature) results because the focal plane is actually not planar, but spherical. Spherical aberration occurs in a spherical lens or mirror because these do not focus parallel rays to a point, but instead along a line. Therefore, off-axis rays are brought to a focus closer to the lens or mirror than are on-axis rays.

Another interdisciplinary field, engineering management has grown in recent years, with universities responding to industry demand for management-focused engineers by developing dedicated engineering management programs. These courses combine industrial engineering skills and business expertise, often developed jointly by the engineering and business faculties. You could also study one of the above branches of engineering with management.

This is a very broad subject, which overlaps with lots of other types of engineering. However, the most common specializations of mechanical engineering include manufacturing, transportation systems, combustion, nanotechnology and robotics. Mechatronics engineering may also be of interest; this combines mechanical and electronic engineering with areas such as computer and control engineering. Read more here.

You could specialize in the following areas of electrical and electronics engineering: power generation and supply, communications and media, computer systems and robotic systems. You can learn more about these here.

If you study aeronautical engineering, you could specialize in aerodynamics, aeroelasticity, composites analysis, avionics, propulsion and structures and materials. Find out more here.

"The best part of my degree is getting to know more about how important my job as an architect is: the hidden roles I play, that every beautiful feature has significance, and that even the smallest details are well thought out."

Engineering is an extensive subject, and with so many types of engineering to choose from, it can be difficult to narrow down which one is for you. To help you to decide, you should try and identify what you’re passionate about. What gets you excited, and what do you spend your free time on? All types of engineering include some form of problem-solving (and generally focus on making life easier), but what engineering-related solution gives you the biggest buzz? If you choose a subject you’re naturally interested in, you’ll find it easier to stay motivated during your course and stay involved with the subject whilst pursuing an engineering career.

Civil engineering is the professional practice of designing and developing infrastructure projects. This can be on a huge scale, such as the development of nationwide transport systems or water supply networks, or on a smaller scale, such as the development of single roads or buildings.

Computer engineering concerns the design and prototyping of computing hardware and software. This subject merges electrical engineering with computer science, and you may prefer to study computer engineering alongside one of these similar subjects.

If you choose to study chemical engineering, you may like to specialize in chemical reaction engineering, plant design, process engineering, process design or transport phenomena. You can read more about these here.

One of the oldest and broadest types of engineering, mechanical engineering is concerned with the design, manufacturing and maintenance of mechanical systems. You’ll study statics and dynamics, thermodynamics, fluid dynamics, stress analysis, mechanical design and technical drawing.

You may find that computer engineering specializations overlap with those offered in computer science degrees, for example with subjects such as computer graphics and network security. However, specialized subjects generally unique to computer engineering include microprocessor/microcontroller systems, computer architecture and VHDL (hardware description language) design.

"I have so many wonderful memories of my MBA and I think, for me, the biggest thing that I've taken away was not what I learned in the classroom but the relationships, the friendships, the community that I'm now part of."

This branch of engineering deals with the research, design, development, construction, testing, science and technology of aircraft. You could also study astronautical engineering, focusing on spacecraft and the deep conditions of space.

"CUHK’s MBA programme provided me with the stepping stone into a larger sports Asian market wherein I could leverage the large alumni network to make the right connections for relevant discussions and learning."
