Celazole PBI (Polybenzimidazole) is an impressively high performing engineering plastic, offering the highest mechanical properties compared to any other unfilled thermoplastic over 400° F. It is an ideal plastic for elevated heat bushings, valve seats, and connectors. This material is very hard and has amazing ultrasonic transparency, making it a superb option for probe tip lenses in ultrasonic measuring equipment and other similar parts.

Also referred to as Duratron PBI, Celazole is an unreinforced material that is exceptionally “clean” when it comes to ionic impurity, and it doesn’t outgas, with the exception of water. It is a superior thermal insulator. While other plastics in melt stick to other materials, this does not happen with polybenzimidazole, as such it makes it ideal for a number of applications.

Examples of applications that Celazole is commonly used for include, but are not necessarily limited to:

• Seals and wear surfaces
• Valve and pump seats
• Handling parts and fixtures for plastics and glass manufacturing
• Replacement for metal for aerospace components
• Structural and wear parts for manufacturing involving Semiconductor and Electronics

High performance engineering machinable shapes, such as Celazole, are perfect design starting points, lessen weight, and expand the length of time before maintenance or replacement is required. This reduces the overall expense though the increase in process uptime, making this innovative plastic exceptionally valuable.

Given the changing direction and magnitude of support for research sponsored by the federal government and industry, coupled with the increased competition from federal laboratories and international groups, engineering colleges must look for new opportunities to establish collaborative research alliances. Some alliances may be local or regional; others will be “virtual,” that is, national or international alliances established through the emerging global information superhighway.

Regional consortia of engineering colleges, for example, may share research facilities, teaching laboratories and faculty. Faculty tenure might even reside with a consortium and not with the individual institutions. Other types of consortia could combine the resources of universities and industry, universities and federal facilities – such as national laboratories – or a combination of all three. The aim is not to create new bureaucracies and expense, but to facilitate high-quality research and teaching that is both effective and efficient.

The National Science Foundation has taken the lead in funding experiments in research and education resource-sharing, and in creation of virtual research and education teams. Such experiments also should be encouraged through the Engineering Research Center (ERC) and Science and Technology Center (STC) programs. Lessons learned by the NSF Engineering Education Coalitions in creating “virtual” research and education teams should be applied to these experiments.

To ensure high-quality research and education, federal funding for science and technology must be distributed through open competition, based on peer review. To enhance technology transfer and industry-university research partnerships, universities, corporations and federal agencies should ensure they have flexible and negotiable policies governing intellectual property rights.

Federal agencies that fund research and education should explore ways of encouraging educational institutions, research organizations, federal laboratories, and industry to share resources. They should provide special consideration for funding projects that are developed by consortia of institutions.

Engineering education today is adapting to the changing context of engineering practice, but more can be done to speed and improve the process. A crucial means of accomplishing needed change is through partnerships with industry, government, and the broader educational communities. The policy statements and action items developed in this project are intended to help ensure that engineering education will be RELEVANT, ATTRACTIVE and CONNECTED well into the next century.

Through its accreditation process, the U.S. engineering education system has continually reexamined and re-energized the engineering curricula. Engineering fundamentals have been and will continue to be the core of the engineering curriculum. But because engineers now operate in a world where their accomplishments are often more limited by societal considerations than by technical capabilities, they are engaging in a wider range of activities throughout their professional lives. Thus, engineering education must take into account the social, economic, and political contexts of engineering practice; help students develop teamwork and communication skills; and motivate them to acquire new knowledge and capabilities on their own. Because many modern engineering projects require a combination of several disciplines, students also need exposure to the integrative field of systems engineering.

In essence, an engineering education today aims to prepare an engineer to be successful in the changing workplace. It aims to equip students with technical knowledge and capabilities, flexibility and an understanding of the societal context of engineering.

Engineering schools should not seek to develop these contextual and process skills through separate courses, but by incorporating them into existing curricula and through non-classroom activities. Coursework should feature multidisciplinary, collaborative, active learning; and take into account students’ varied learning styles.

One factor that will promote development of students’ “process” skills is widespread use of multimedia, worldwide information networks. Using this resource, students can access new information and coursework, as well as interact with other students, researchers, practicing engineers in industry and government, and experts from around the world. These changes in the teaching and learning environment will make engineering education more attractive to both students and faculty, if faculty are given the opportunity to stay up-to-date.

Finally, all engineering colleges must address the issue of ethics. While ethics is a complex and difficult topic, engineering administrators and faculty must help students understand that throughout their careers they will encounter ethical issues which they will need to recognize and deal with rationally. Whether engineers are conducting engineering research, managing a company, or building bridges and office buildings, their decisions affect the lives and property of the greater community. Students must understand the importance of upholding that public trust.

While recognizing and encouraging diverse institutional missions and changing industry needs, colleges of engineering must re-examine their curricula and programs to ensure they prepare their students for the broadened world of engineering work. This process has begun among most engineering colleges and must be accelerated with the aim to incorporate:

• team skills, including collaborative, active learning;
• communication skills;
• leadership;
• a systems perspective;
• an understanding and appreciation of the diversity of students, faculty, and staff;
• an appreciation of different cultures and business practices, and the understanding that the practice of engineering is now global;
• integration of knowledge throughout the curriculum;
• a multi-disciplinary perspective;
• a commitment to quality, timeliness and continuous improvement;
• undergraduate research and engineering work experience;
• understanding of the societal, economic and environmental impacts of engineering decisions;
• and ethics.

Indeed, a degree in electrical engineering can open many doors, in part because electrical engineering is so broad. Electrical engineers have taken on many tasks that you might expect people with other technical degrees to do. Semiconductor processing, for example, is highly populated by electrical engineers, but its basis is in physics and chemistry. Other areas include optics (as applied to communications), aerospace engineering, and even life sciences. “A lot of people don’t realize that a lot of biomedical devices are actually electrical devices,” noted Georgia Tech’s May.

Engineering jobs also cut across technical disciplines. More and more, mechanical, chemical, and biomedical engineers use electronics to measure a product’s performance. “Who says you’re not going to do test and measurement on a chemical process for drug manufacturing?” asked Looft. “That’s a huge area. And you better know a little bit about chemical processing when you go into that job.”

Some people with engineering degrees move out of engineering jobs but stay in their respective industries by moving into sales, marketing, and management (a few even become editors covering the industries from which they came). Others move into fields such as law and medicine. Law firms, looking for patent lawyers with technical backgrounds, may hire engineers or engineering graduates and pay for law school.

Those who choose to enter the engineering work force may find that they need skills beyond math, science, engineering basics, and problem solving. We asked the participants what additional skills employers now look for in engineering graduates. While we received some differing answers, everyone agreed that communications skills sit atop the list.

No longer is it enough to design circuits and get test results. You must communicate those results through written reports and presentations. Georgia Tech’s Williams noted that the university has integrated writing of technical documents into several courses, which UCSB’s Long echoed. WPI has even created an interdisciplinary major or double major in technical writing.

While schools have responded to employers looking for better communications skills, some in academia remain skeptical. One such person is Professor John Orr of WPI. “The standard example is if you hear an after dinner speech from the VP of company xyz, [he or she] will describe that employers need graduates with good communications skills, good teamwork skills, and some global experience. But when hiring managers come to campus, they look for skills such as experience with the latest Cadence software release. They’re looking for engineers who can be productive from day one.”

Regardless of whether communication courses are included, it’s becoming virtually impossible for schools to provide all of the required engineering skills at the undergraduate level. In fact, some people have begun to question if you should be able to enter the engineering work force with just a bachelor’s degree. Employers are looking more and more for graduates with master’s degrees, and the number of master’s degrees relative to bachelor’s degrees has risen in the past 30 years (Figure 1). (continued)

At the same time, the number of PhDs has remained relatively flat. During the last business downturn, companies may have scaled back their research budgets, relying on universities to do the work. “There’s a lot less research going on in industry than there used to be,” said UCSB’s Long. “Most companies have decimated their research labs.” Long argued that companies are looking for fewer PhDs than they did 10 or 15 years ago because they don’t have the facilities and don’t want to pay the higher salaries.

In recent years, industry has become more involved with academia. That’s good for the most part, as long as industry lets the teachers teach. Often, companies sponsor student projects or contribute to the funding of research labs. Students benefit from having worked on real-world projects and by making industry contacts, which can lead to employment upon graduation. Employers benefit because they can hire graduates with practical experience.

Overall, industry involvement in projects is welcome, because the companies provide equipment, materials, and sometimes funds for student projects. “If they’re paying for a project, then they should have the say over the project,” said WPI’s Looft. “But it can get too involved. I have companies that want to tell us what we’re going to do, educationally.”

Drexel’s Kam doesn’t agree. “I’m sure that there are horror stories here and there of companies who donated the equipment and wanted to control the curriculum,” he said. “But I wouldn’t call it a trend nor would I say this is widespread.” Georgia Tech’s May agreed that a few companies want too much involvement, but he doesn’t think it’s excessive. Companies are, after all, stakeholders in the graduates that these universities produce.

Looft said that companies go over the line when they say “you didn’t get it done” meaning that a student project didn’t produce a marketable product. When that occurs, he reminds companies that a student project is an educational endeavor that may not produce a working product.

Kam takes a different approach. He argued that companies need to get more involved in the educational process. “Industry is absent from the accreditation process,” he said. He wants to see greater participation from industry so universities can produce the engineers best qualified to keep companies competitive.

Whether you think the world has too many or too few electrical engineers, you’ll probably agree that engineers make an impact on people’s lives every day. Engineering has proven to be a satisfying career for many. Your work makes a difference in the world. Now, go out and tell someone how engineers contribute to society. I am sure many engineers proud to wear lanyards around their neck about their company.

What is engineering? What is an engineer?? Although it is a very old activity or trade, engineering is a relatively young academic discipline or profession. Only in recent years has it reached a stage of maturity where some of its defining details and differentiating characteristics can be articulated. Engineering is the endeavor that creates, maintains, develops, and applies technology for societies’ needs and desires. Its origins go back to the very beginning of human civilization where tools were first created and developed. Indeed, a good case can be made for the defining of humans as those animals that create, develop, and understand the significance of technology.

Over time, the part of technology that acts as an extension of human capabilities became the purview of engineering. One can view bicycles, cars, and trains as extensions of walking and running. Airplanes are an extension and application of a bird’s ability to fly transferred to humans. The telegraph, telephone, radio, television, and the internet are extensions of talking, hearing, and seeing. The microscope, telescope, and medical x-ray are also extensions of human sight and vision. Writing, books, libraries and computer data-bases are extensions of human memory and the computer itself is an extension of the human’s brain in doing arithmetic and carrying out logical arguments and procedures. Indeed, looking around your environment in almost any setting, will illustrate just how pervasive technology is. In almost any home or office, there is very little that is truly “natural”; i.e., little that is not created or manipulated by technology. The food that you eat, the utensils that you eat with, the table that you eat off of, the house that you are in, the clothes that you wear, the book that you read, the television that you watch, the telephone that you communicate with, the car that you travel in — these are all technologies created by human cleverness to satisfy human needs. This process of creation is engineering and those who do the creating are practicing engineering, whether they call themselves engineers or not.

Not only is much of the inanimate world created by engineering, part of the living world is also. Almost all crops and agriculturally produced food stuff are “engineered” through selective breeding. The same is true of domestic animals such as pets and animals raised for food or sport. Certainly the dogs, cats, and cattle have not “naturally” evolved to their current state. They have been “created” or “designed” to satisfy human desires or needs. The slow and less exact methods of controlled breeding are being replaced by genetic engineering, tissue engineering, and applications of nanotechnology. We humans have the cleverness to do that. It is the development of the tools, theories, and methods and the understanding of the appropriate sciences and mathematics for that process that is engineering. It is a central part of the history of humanity.

Not only has engineering made our lives easier and longer, it has sometimes made them more terrible and shorter through improving our ability to kill and harm when we wage war. Indeed, military and defense needs have been a historic driver of technological advancement. One of the earliest categorizations of engineering was into military and civilian (or civil) engineering.

Because technology enables and causes change, it and its creators, the engineers, are viewed with mixed feelings. This is especially true in modern (perhaps post-modern) times when the negative side effects (“unintended consequences”) of technology must be addressed.

This note is an attempt to address the question of what engineering is and then that of what an engineer is. It is intended for the general public to better understand just what this thing that has such a profound effect on our individual and collective lives is. The note is intended for the student who is considering becoming an engineer and, therefore, it is for parents and high school and college counselors as well. It is for the university engineering student and professor and for the university administrator. It is for the state and federal governments who fund engineering education and research and the investor who invests in technology. It is for the husband, wife, parent, or child who wants to better understand their spouse, child, or parent. It is for everyone who accepts the argument that a human is a technological animal and that technology has a pervasive effect on our lives.

An important part of this note is the list of references. This collection of short essays is intended to open many topics and ideas, not develop them. A rather long list of references is given to allow the reader to pursue any of the many ideas further.
