An engineer uses science, technology and math to solve problems. We can see engineering everywhere in the world around us, improving the ways we work, travel, communicate, stay healthy, and entertain.
Today, the field of engineering offers more career choices than any other discipline. In the past, there were four major engineering branches: mechanical, chemical, civil and electrical. Today, the number of available engineering degrees have greatly increased. There are now six major branches of engineering: mechanical, chemical, civil, electrical, management, and geotechnical, and under each branch there are hundreds of different subcategories.
What does an Engineer do?
Engineers design machinery, build skyscrapers, and oversee public works, but they address society's needs and problems on so many other levels as well. At a molecular level, they work on drug delivery systems that work inside cells. At a macro level, they quantify the particle flow of pollutants through soil to clean up oil spills, abandoned industrial sites and other biohazards. At a galactic level, they are designing spacecraft for other-planet exploration. At an atomic level, they are developing data storage that focuses on the spin of electrons in atoms. Clean drinking water, safe food storage, and the protection of our environment are also under the domain of the engineer.

8. Addressing climate change through engineering innovation
By 2050, six of the 10 cities with the largest annual flood costs will be in Indian and China. Three will be in the United States: New York, Miami, and New Orleans.
9. Feeding the growing world population through cutting-edge bio-engineering and agricultural innovations
The United Nations warns that by 2050 world food production must increase by 60% to keep up with demand. The challenge is to reach this goal in a sustainable way and ensure food and water access.
10. Improving health and well-being through life sciences, nanotechnology, and bio engineering
By 2060, the population of Americans aged 65 and older will have more than doubled in size from 2011. This puts a lot of pressure on new drug creation and on engineering techniques to deliver drugs.
It is important to find an engineering field where you are really interested in the core content. Just because some engineering fields are considered to be the fields to get into and everyone seems to be flocking in that direction, doesn't mean you have to as well. If something doesn't appeal to you, then it's not the right major for you, so avoid it.
Try and get into classes early on that you suspect are going to be your major. That way, you can discover if it's the right fit for you. Two good questions to ask yourself are, 'Am I really enjoying this?' and 'Do I have what it takes to truly excel in this field?' Also, try to avoid taking all the 'fluff' courses during your first couple of years. That will ultimately leave you with all the really hard ones during your final years, and you won't have anything to break up all the hard core engineering work.
It wouldn’t be advisable for a person who wants to become an engineer to first major in mathematics with the view to deviating at a later date toward engineering. It is true that a lot of mathematic principles apply in the world of engineering, but engineering is far more practical and ‘hands-on’ and one could not major in mathematics and expect to secure employment right away as an engineer.
If, however, you have majored in mathematics and find yourself looking thereafter to pursue a career in engineering, you are certainly ahead of someone who has majored in something completely unrelated. There are some specialized areas of engineering in which a mathematician could work, but you will still have to undergo further training and obtain the relevant qualifications, or at the very least assume an internship or relevant work experience.
Also relevant for Mathematician
The 'best engineering degree' will, of course, be subjective, and be different for each person. The choice a student makes will be based on a couple of things - where his/her interests lie, and what field has the best outlook for the future.
If looking for an engineering field that is growing at a rapid pace and is linked to advancing almost every major industry in the future, then software engineering is at the top of the list. If higher pay is a top criteria, then petroleum engineering and chemical engineering are good fields to look into. The biomedical engineering field is expected to grow 62 percent by 2020 due to the aging baby-boomer generation and advances in medical technology. Environmental engineering is expected to grow by 22 percent by 2020, and civil engineering by 19 percent.
Again, it's good to remember that the best engineering degree (and ultimately the best job satisfaction) may be completely different than what it is for someone else. Opt for the field that will be the most rewarding and fulfilling for you as an individual, as there really isn't a 'bad' engineering field.
Sometimes an engineer will have a personal internal change during their career in which their professional path and interests start to veer from a product-thinking environment to a market-thinking environment (inward focus vs outward focus). It would be recommended to get certified in product management and even think about getting a master's of business administration degree if this is a path you'd like to pursue.
This can be a great career choice, as an engineer already has the technical background and understands the technology. It would be good to read books, blogs, and go to events pertaining to product management. Finding a mentor that has been a product manager for a few years would be excellent as well, as he/she can answer questions and help guide you through the process.
Engineering can be an excellent career choice for someone that has the aptitude, a keen interest, strong math skills, and a logical approach to problem solving. Engineering majors have the reputation for being very demanding, sometimes taking five years to complete. It might be difficult to go through all the math and science involved, and you may wonder if it's worth the amount of work involved (especially when seeing students in other programs having a lot more fun than you).
Remember that you must put in the hard work to achieve any type of success, and becoming an engineer is, in the end, a rewarding and satisfying career. It will enable you to create, test, and design things that solve the world's problems, and it will offer endless growth opportunities. If you pick your engineering field wisely and keep true to yourself and your strengths, it will definitely be worth your effort.
Many aspects of our lives have been visualized, designed, and developed by an engineer. To engineer literally means 'to make things happen'. Most of what engineers do on a daily basis can fall into four categories: communicating, problem solving, analyzing, and planning. Depending on an engineer's industry and role, their day will typically consist of a various mix of these functions.
Engineers take scientific knowledge and convert it into technology, and then take that technology and convert it into a working solution/innovation. There is a sense of pride and well-being that all engineers feel after having completed a difficult project successfully. It is a life-rewarding career: creating, designing and producing useful products and services for others.
