Engineering Challenges
In a previous article (Preservation - The 21st Century Engineering Challenge, February 15, 2007), I wrote about the Engineering Challenges web site established by the National Academy of Engineering (NAE). The purpose of this web site was to solicit ideas as to what should be the "Grand Challenges for Engineering" for the twenty-first century. The NAE has about 2,000 members, all elected by their peers, and all superstar engineers. The list of submitted topics was reviewed by an expert panel [1], chaired by Former Secretary of Defense, William Perry. This panel announced its final list earlier this year at the annual meeting of the American Association for the Advancement of Science (Boston, February 15, 2008). The final challenges fall into four theme areas: health, sustainability, enhanced security, and quality of life.
• Engineering better medicines
• Advancing health informatics
• Providing access to clean water
• Providing energy from fusion
• Making solar energy economical
• Restoring and improving urban infrastructure
• Enhancing virtual reality
• Reverse engineering the brain
• Exploring natural frontiers
• Advancing personalized learning
• Developing carbon sequestration methods
• Managing the nitrogen cycle
• Securing cyberspace
• Preventing nuclear terror
All of these are worthy goals, but I have some criticism of this list. Although solar and fusion seem to be viable "carbon-zero" energy sources, it's a mistake to single-out these technologies. Instead, the goal should be "economical, renewable energy" in itself. Preventing nuclear terror is too specific, also. Bio-terror may be more dangerous, so the challenge should be "terror prevention." Of course, this leads to the uncomfortable debate about funneling money into social programs and psychological research to stem terrorism at the root cause. The Engineering Challenges web site asks its readers to vote on their favorite challenges; but making a selection from this list would be like answering the question, "Do you still beat your spouse?" Your selection may not be on the list.
Robert Socolow, a professor of mechanical and aerospace engineering at Princeton University and a member of the panel, said in an interview [4] that one motivation for the list was "to make sure that young people know that engineering is an exciting profession, one that makes a difference to society." The Engineering Challenges project is sponsored by a grant from the U.S. National Science Foundation, Award # ENG-063206.
