Abstract:
The Practice of Engineering In The 21st Century
The large looming problems that must be solved
lie at the interface between technical challenges
and human needs. In early 2008 the National Academy
of Engineering assembled an international group
of leading technological thinkers who were asked
to identify the Grand Challenges for Engineering
in the 21st Century. Fourteen areas were identified
as needing to be solved and all 14 lie at this
interface between recognizing human need and connecting
need to resources, solutions and appropriate technologies.
The Grand Challenges (opportunities) include providing
access to clean water, restoring and improving
urban infrastructure, securing cyberspace, managing
the nitrogen cycle, making solar energy economical,
engineering medicines, developing carbon sequestration…

Solutions to these challenges will only be found
by a creative work force - one that is technically
trained and has the ability to move seamlessly
across disciplines. Engineering by definition is
a connecting force among disciplines. It is the
practice of bringing technical solutions to human
needs. In ones preparation, integrating the arts,
the humanities and the sciences with engineering
provides the breadth and depth needed to think
critically, act reflectively and make informed
choices. Dean McMahon understood this and the importance
of a contemporary educational model that included
at its heart a learner-centered pedagogy in which
the practice of the profession via research and
design remains a focus.
This need for interdisciplinarity and creativity
will be highlighted in this lecture through a presentation
of the advancements being made in the field of
carbon science and engineering -- laboratories
on a chip using carbon nanoprobes, graphene transistors
as the barrier breaker moving us toward terahertz
processor speeds, nanoradio, defect controlled
activated carbons for water purification (H2 adsorption)
and sequestration technologies, and structural
carbons and composites that realize extremely high
specific strength and moduli while maintaining
integrity at high temperatures.
