Section D        One of the most impeccable vocations one could pursue is engineering. Engineers, thoughintricate, play a central role in transforming our world into a safer, more enjoyable place tolive. Consider just one area, which is very close to each of us: our own health. Biomedicalengineers have designed incubators that sustain the lives of premature babies, devices andprocedures to diagnose conditions and fight diseases, and equipment to restore bodilyfunction such as being able to walk or to see. Agricultural and biological engineers developmedicines, create better ways of growing and protecting our food supply, and along withenvironmental engineers, help to create a cleaner, safer environment in which to breathe, growfood, and have safe drinking water. Even if you have not come across such an engineer before,they have set an example of how to be good stewards of our resources, and we are thebeneficiaries of what they have done for us.        What exactly is engincering? It is practical application of science knowledge. There aremany different areas of engincering. Dr. Seuss help to open our minds to all the possibilitiesof what we can do in life in his book Oh, The Places You'll Go! Engineers make this a reality,both literally and figuratively. In the area of transportation, engineers design vehicles to helpmany people daily get from one place to another, as well as airplanes, space shuttles, andsubmarines that enable us to explore the far reaches of the planet and beyond. More broadly,there are four major branches of engineering, including chemical, civil, clectrical, andmechanical engineering, each of which has a number of subdisciplines. Then there aredifferent interdisciplinary areas of engineering. From the smallest scope, where nanoengineersand biomolecular engineers design at the level of atoms and molecules, to the largest scope,where civil engineers design bridges and buildings, the options are many.        Being an engineer is intellectually stimulation and provides continual chal lenges. You willlearn not only how things work, but also why different materials such as woods, metals, orplastics have the properties that they do, depending on their atomic structure and how theywere formed. You become trained to identify what problems may exist and how to use yourknowledge, skills, and creativity to figure our innovative solutions to fix them. Oneinteresting challenge outlined by the National Academy of Engineering is to figure out how tocontrol a fusion reaction to provide us with energy in a more efficient, economic, andenvironmentally friendly way. Or how about discovering how to diagnose and treat cond itionspeople have, based on indi vidual differences? Quickly assessing someone's genetic profileand having a way to deliver patient-specific medications to precise locations usingnanoparticles are important engineering challenges that could improve many people's lives.        It is hard to imagine what life would be like without the contributions engineers havealready made. They have not just helped us to survive, be healthy, explore, and move aroundbetter, but they have also made life more enjoyable through advances in areas such ascommunications, computing and sports. Computer engineers, for example, have helpeddevelop devices and software that we can use to make and share documents and home videos,listen to our favorite music, and talk with co-workers, friends, and family members across theglobe. In sports, different engineers have made systems and devices that provide us withbetter, safer equipment, communications that enable teams to interact better and games to betelevised, and environments and infrastructure that improve the playing and watching games.        It is true that everyone has unique desires, so you may prefer a vacation in some other area.But even our desires themselves can be changed and nced to be developed, so why not tryengineering on a smaller level with a project around the house or follow an engineer aroundfor a while? It might just become the kind of thing you would enjoy doing even if you werenot getting paid, and perhaps you could become the next Orville or Wilbur Wright, coming upwith a whole new design that takes us to new heights. Consider also the fruits of engineers'labors: if they have benefitted you so much, why not do something that could benefit others inkind? At the very least, we need to be aware that without the contribution of engineers, ourlives would be "more impoverished", so we have a lot for which to be thankful.
