3. Scientists Investigate that which already is; Engineer Creates that which has never been - Albert Einstein

4. What You Need To Know About Engineering!  Engineering combines the fields of science and maths to solve real world problems that improve the world around us.  What really distinguishes an engineer is his/her ability to implement ideas in a cost effective and practical approach.  The ability to take a thought, or abstract idea, and translate it into reality is what separates an engineer from other fields of science and mathematics.

5. Reality about Engineering Consider some things you use in your everyday life: Buildings, roads and bridges, vehicles (cars, planes and boats), computers and other electronic devices. Not a single one of them would exist without engineers! You wouldn’t have been able to drive to work, check your facebook status or even use the toilet this morning! http://mit.tv/wJfv7y

6. What Does A Typical Engineer Do?  Engineers are problem solvers, organizers, communicators, calculators and designers.  They are capable of clearly defining a problem and its relevant constraints (such as time, cost, etc.) and providing a simple solution.  A senior engineer will usually perform less technical work (calculations and designs) but instead focus on managing a project or team of engineers.

7. What does and engineer do? Engineers do the following:  Design  Evaluate  Develop  Test  Modify  Install  Inspect  Maintain In What? : A wide variety of products and systems. They also recommend and specify materials and processes, supervise manufacturing and construction, conduct failure analysis, provide consulting services.

8. How Different Engineers Work Together An Illustration of Tunnel Design  A civil engineer who specializes in structural design (structural engineer) would calculate the size of the tunnel, how it is to be constructed (all of the stages) and what it is made of (reinforced concrete, etc.).  In order to provide clean air and remove as much of the vehicle emissions as possible, a mechanical engineer is employed to design the ventilation system. The mechanical engineer would plan for the amount of emissions that need to removed and the process of removing them (for instance how many of a particular type of fan would be required and where they are to be installed. Don’t forget they also have to figure out where this air flows to).  An electrical engineer will design the lighting as well as any control systems for hazard signs.  In some cases, specialist disciplines such as environmental engineering are used to conduct an investigation into the sustainability and environmental effects of building such a tunnel.

9. Do Engineers Work As Individuals?  The answer for this is dependent on the specific project, job and even field that engineers work in.  Generally, all engineers work as part of a small or large team. Answer: NO

10. Is Engineering Boring And Repetitive?  It is inevitable in any job, really, to have to perform dull and mundane tasks.  Engineers are required to check calculations (which are vital so nothing explodes or collapses!), read technical papers and write technical reports.  The true value found in engineering is the ability to combine all tasks to create something greater (think 1 + 1 = 3!). This can’t be achieved without a team working together towards the same objective.  Consider that many other professions such as accounting, teaching and even business studies all have their own mundane and repetitive tasks – it’s the ability to create something special like a two-hundred story skyscraper or a car that runs on electricity that makes engineering stand out!  Engineering provides you with the opportunity to contribute to society and leave a lasting impression on the world Follow in the footsteps of engineers like Thomas Alva Edison whose inventions are still used today!

11. 3 Reasons Why You Should Choose Engineering There will always be a demand for skilled engineers in many different fields, some of which are brand new, emerging areas while others have existed for 500 years. As society develops and improves, engineers are called upon to make these changes to create a better, sustainable world to live in. Deciding to study engineering is a personal choice that only you can make; so what are the three best reasons why you should choose engineering?

12. Reason #1  Engineering Is The Ultimate Field For Challenge And Creativity Engineers work on exciting projects and influence how our world changes and improves. The amazing structures, vehicles and discoveries in modern society have been influenced and created by engineers in some capacity. If you are curious about how things work and have a keen mind for applying what you learn to solve real world problems, engineering is the perfect avenue for your talents. Be prepared to dedicate years of learning and practice to master a field of engineering; don’t expect to build an A380 airbus or the next Burj Khalifa (currently the tallest building in the world) within a year of completing your degree.

13. Reason #2  Learn Skills You Can Apply Anywhere The skills that you develop as an engineer are incredibly valuable and highly sought after. People will turn to you to help solve problems for them. The ability to provide practical solutions to problems is crucial and will give you great confidence when faced with any challenge or obstacle. You will develop an understanding of the feasibility of a project from a financial and practical perspective. You also learn how to manage your time effectively, work as a part of a team and develop into a true leader. These skills can be applied to any area of your life.

14. Reason #3  Great Rewards And Opportunities As an engineer you will rank amongst the highest paid professions in the world, even as a graduate. Your unique, universal skill set will enable you to work in almost any country in the world (and beyond!). Not many careers offer this sort of opportunity to gain experience and explore new cultures and lifestyles. Engineers working in multinational companies will often travel overseas for conferences and to visit or inspect company facilities, adding variety to their daily routines. Ultimately, there is no perfect formula or criteria for determining your suitability to become an engineer. One of the first, and easiest, steps you can take to determine if you would enjoy engineering is to discover which industry or discipline you would like to work in. Once you have an idea of the field you would like to work in, find out which qualifications you need to obtain. (www.onetonline.org )www.onetonline.org

15. Disciplines of Engineering  Engineering is broad field that is divided into various disciplines and sub-disciplines. The disciplines of engineering can be divided into three main categories: a)Civil Engineering b)Electrical Engineering c)mechanical engineering. Each main discipline will provide you with a “taste” of the various skills and knowledge required to work in any field related to the discipline.

16. Role of Civil Engineer Civil engineers: Design Construct Supervise Operate Maintain What? : Large construction projects and systems, including roads, buildings, airports, tunnels, dams, bridges, and systems for water supply and sewage treatment. These engineers may also handle site preparation activities, such as excavation, earth moving and grading for large construction projects. Additionally, civil engineers may conduct or write the specifications for destructive or nondestructive testing of the performance, reliability and long-term durability of materials and structures.

17. Role of Mechanical Engineer  Design and Develop anything that moves.  Mechanical engineers use basic components that have been known and used for centuries — such as wheels, axles, levers, screws, springs and hinges — to make machines such as vehicles, farm machinery, household appliances, robots and industrial equipment.  Mechanical engineers also design sub-assemblies for these machines, including control systems and instruments as well as individual parts.  Movement can be powered by the muscles of humans or animals, heat and pressure of combustion, hydraulic or pneumatic actuators, electromagnetism, gravity or springs of all shapes and sizes. Therefore, a mechanical engineer must be familiar with all of these basic motion and power components in order to design more complex devices. For instance, in an automobile, the starter motor uses electromagnetism; the engine is powered by expansive pressure from the combustion of gasoline; the power steering, brakes and automatic transmission use hydraulic pressure; and the suspension system uses springs.

18. Role of Electrical Engineer (EEE, ECE) Electrical engineers design, develop, test and supervise the manufacturing of electrical equipment, such as electric motors, radar and navigation systems, communications systems and power generation equipment. Electronics engineers design and develop electronic equipment, such as broadcast and communications systems — from portable music players to global positioning systems (GPS). Today’s electrical engineers design electrical devices and systems using basic components such as conductors, coils, magnets, batteries, switches, resistors, capacitors, inductors, diodes and transistors. Nearly all electrical and electronic devices, from the generators at an electric power plant to the microprocessors in your phone, use these few basic components.

19. Role of Computer Engineers Computer hardware engineers "research, design, develop and test computer systems and components such as processors, circuit boards, memory devices, networks and routers. Computer hardware includes:  microprocessors;  memory chips: random-access memory (RAM), read-only memory (ROM) and nonvolatile rewritable flash memory;  data storage devices: hard disks, solid-state drives and optical drives;  input devices: keyboards, mice, joysticks and gaming controllers, cameras, microphones, scanners, touch screens and remote sensors;  output devices: printers, monitors, audio devices and remote controls; and  networking components: adapters, modems, switches and routers. An important function of computer engineers is to integrate these components into computer and network systems. This all requires a good working knowledge of electrical engineering. Another important aspect of computer engineering is software development. Computer software includes:  operating systems;  applications: word processing, spreadsheets, accounting, database management, graphics, computer-assisted design (CAD), computer-assisted manufacturing (CAM), audio, video, media and games;  networking and communications: World Wide Web (WWW), voice over Internet Protocol (VOIP), instant messaging and email;  utilities: file handling, disk management, device drivers, archiving and backup systems;  programming languages: editing, compiling and debugging; and  security: antivirus, firewalls, encryption and user authentication.

20. Role of Chemical Engineers ( Bio Tech, Petroleum Engg.) Chemical engineers apply the principles of chemistry, biology, physics and math to solve problems that involve the production or use of chemicals, fuel, drugs, food and many other products. Chemical engineers work in a variety of fields. For instance, they may work at a petroleum refinery to turn crude oil into gasoline, jet fuel, diesel fuel, lubricating oil, solvents and petrochemicals; at a fertilizer plant to produce ammonium nitrate, or at a personal-care product manufacturer to mix dozens of ingredients to produce shampoo or skin lotion.

21. Computing Skills : An essential aspect for every engineer  Software Tools, Computing tools, Simulation tools have become and integral part of engineering design in every discipline of engineering.  Computer Coding and Programming skills are essential to designers in every engineering discipline. Easier, quick and accurate generation of needful designs, processes, analytical models and techniques has made Computer a main frame entity in professional life of every engineer irrespective of his/her discipline of engineering
