What is engineering?

The application of science and mathematics to harness useful products from natural resources is known as engineering. The United States Engineers Council for Professional Development defines engineering as the creative implementation of scientific principles to create something new.

What are the different types of engineering?

Engineering has a lot of different branches and it roots from the different scientific subjects. The most common branches of engineering are –

  • Civil engineering
  • Mechanical engineering
  • Chemical engineering
  • Petroleum engineering
  • Electrical engineering
  • Aerospace engineering

With time and newer complexities being addressed, we now have additional fields of engineering, like, genetic, management and geotechnical engineering. Each of these branches, have thousands of sub-branches making engineering quite the diverse subject that find creative ways to solve the real-time problems of the world.

What is the history of engineering?

In 2550 BC, the world witnessed its first engineer – Imhotep, who was the one responsible for building the Step Pyramid in Egypt. It was the first time that people were introduced to civil engineers. Following Imhotep, a lot of Persian, Egyptian, Greek and Roman civil engineers popularized civil engineering by using empirical methods along with mathematics and physics. It was in the 18th century, that civil engineering was recognized as a separate entity.

Electrical and electronic engineering roots from the experiments of developing electric motors and dynamo from an electric cell by Michael Faraday. Scientists like James Maxwell and Heinrich Hertz popularized electronics engineering. In the mid-20th century, the discovery of transistor had a profound impact on the market. And by the late 20th century, the maximum number of engineers in the world were from the branch of electrical and electronics.

Industrialization gave its way to the rise of chemical engineering in the fields of metallurgy, textile and food. The dependence on chemical increased to such a level that by 1880, there was a whole bunch of industries dedicated for just production of chemicals.

What are the types of engineering degrees to pursue?

  1. Computer Engineering Degrees

The present scenario summarizes that one of the most demanding and rising branches of engineering is that of information technology which includes both computer science and electrical engineers.  Once graduating in this disciple, one is assured a job in fields like networking, telecommunications, software application development, web development and cloud computing. While a graduate will also get good opportunities, but the highest degree of masters in the field fetches jobs in top firms which rely on computer engineers more than anything.

  1. Electrical Engineering Degree

Based on the study of energy, an electrical engineer is expected to develop new technologies for harnessing the different forms of energy for human use.  While online and undergraduate programs are scarce, there are quite a few on-campus programs both at the Bachelor’s and Master’s level to pursue this branch of engineering.

  1. Civil Engineering Degree

Dealing with the development of buildings, dams, roads and general construction of different infrastructure, civil engineers have a major role to play in rebuilding projects and contribute to both the private and public sector. Being the head, it can be divided into dub-types like that of environmental, structural and marine engineering.

Structural engineering focusses on the design of different structures and is often available as an integrated course within civil engineering at different institutions.

  1. Mechanical Engineering Degree

Dealing with the design of mechanical systems, a mechanical engineer plays a major role in different streams like manufacturing, nanotechnology, and nuclear power production.

The study of atoms and production of tiny devices is the latest trend highlighting the worlds of engineers. Nanotechnology has the answers to a lot of world problems and can be applied to a wide array of problems.

  1. Biomedical and Biomechanical Engineering Degree

Focusing and implementing the principles of biology and engineering together, these two branches focus on solving issues pertaining to the biological science and medical world. These branches are responsible for the designing and prototyping of new instruments for aiding in diagnosis. They also address environmental challenges and both these fields have lucrative job opportunities.

What path should you follow for a high paying lucrative job?

Engineers are in high demand and some fields of engineering provide the highest-paid job opportunities in the world. Even with little to no experience, engineers on an average earn $100,000 annually which is higher than salaries of most other professionals.

  • Petroleum Engineers –

Petroleum engineers are responsible for digging the earth’s surface to find new reservoirs of petroleum oil and natural gas. They are also responsible for developing efficient and effective methods of extraction, and manage on site processes. With a bachelor’s degree in petroleum engineering, it is quite easy to get a job. In 2014, the median salary of a beginner in the field of petroleum engineering was estimated to be $103,000.

It is expected that the average annual salary of a petroleum engineer with an experience of 15 years or more can be as high as $160,000. With the recent boom in the petroleum and natural gas industry in the United States, the job opportunities are also flourishing. This job doesn’t require high degrees, rather an experience of substantial years can help a person land in a high position making this field an even more lucrative job opportunity.

With so many streams to study and specialize in, engineering is itself a lucrative opportunity for students to start their career. While a bachelor’s degree may take up to four years, but it is enough to get you a decent job which with experience will yield you better opportunities.

Some fields of engineering highlights on having a master’s degree only because they are a branch of some parent subject of engineering and can only be pursued in masters. These courses lay the foundation for research and development of new scientists in the field of engineering.

But, before pursuing engineering, one must have a strong foundation in mathematics, physics, chemistry and technology. These are the basic subjects forming the framework of every engineering course. Even a person pursuing biomedical engineering must have a profound background in the above-mentioned subjects to succeed.

It is true, that the demand for certain types of engineers are increasing but it must also be kept in mind that the number of people pursuing engineering is also increasing as this is the course which has a job assurance after completion of the bachelor’s degree.

So, to get a good job, one must work hard and opt for engineering fields which are in high demand at present.

Given a situation, if an individual gets the opportunity to study nuclear engineering and electronics engineering, what should he opt for?

Given the current situation in the United States, it is always advisable for the individual to pursue nuclear engineering compared to electronics engineering. The nuclear power supplies in the United States are old and aging and they need to be repaired to be able to sustain them for the future. This creates a massive pool of job opportunities for nuclear engineers.

Hence, while choosing the perfect stream to study, one must not only consider the difficulty of the subject or its popularity, but also assess the practical applicability of the subject in the future which is the ultimate source of job opportunities. So, keeping all these points in mind and researching about your own strengths, will help you opt for the stream of engineering that will help you land up with the perfect job.
