Engineer the tools of scientific discovery.
In the popular mind, scientists and engineers have distinct job descriptions. Scientists explore, experiment, and discover; engineers create, design, and build.
But in truth, the distinction is blurry, and engineers participate in the scientific process of discovery in many ways. Grand experiments and missions of exploration always need engineering expertise to design the tools, instruments, and systems that make it possible to acquire new knowledge about the physical and biological worlds. In the century ahead, engineers will continue to be partners with scientists in the great quest for understanding many unanswered questions of nature.
How will engineering impact biological research?
Biologists are always seeking, for instance, better tools for imaging the body and the brain. Many mysteries also remain in the catalog of human genes involving exactly how genes work in processes of activation and inhibition. Scientists still have much to learn about the relationship of genes and disease, as well as the possible role of large sections of our DNA that seem to be junk with no function, leftover from evolution. To explore such realms, biologists will depend on engineering help — perhaps in the form of new kinds of microscopes, or new biochemical methods of probing the body’s cellular and molecular machinations. New mathematical
and computing methods, incorporated into the emerging discipline of “systems biology,” may show the way to better treatments of disease and better understanding of healthy life. Perhaps even more intriguing, the bioengineering discipline known as “synthetic biology” may enable the design of entirely novel biological chemicals and systems that could prove useful in applications from fuels to medicines to environmental
cleanup and more. Turning to the mysteries of our own minds, new methods for studying the brain should assist the study of memory, learning, emotions, and thought. In the process, mental disorders may be conquered and learning and thinking skills enhanced. Ultimately, such advances may lead to a credible answer to the deepest of human mysteries, the question of the origin and nature of consciousness itself.
How will engineering help us explore the universe?
In its profundity, only one question compares with that of consciousness — whether the universe is host to forms of life anywhere else than on Earth. Systems capable of probing the cosmos for evidence surely represent one of engineering’s grandest challenges. Even apart from the question of extraterrestrial
life, the exploration of space poses a considerable challenge. Long-distance human space fl ght faces numerous obstacles, from the danger of radiation to the need to supply sustainable sources of food, water, and oxygen. Engineering expertise will be critical to overcomingthose obstacles, and many efforts to
expand that expertise are underway. One line of research, for example, envisions a set of connected bioreactors populated by carefully chosen microbes. Metabolism by the microbes could convert human wastes (and in some cases the microbes’ own wastes) into the resources needed to support
long-term travel through space. But the allure of space extends well beyond the desire to seek novel life and explore new phenomena. Space represents the mystery of existence itself. The universe’s size and age exceeds most people’s comprehension. Many of its less obvious features have been fathomed by the methods and tools of modern astrophysics, revealing that, amazingly, our entire universe seems to have arisen in an initial fi reball from an infi nitely smallpoint. Matter and energy coalesced into such structures as galaxies, stars, and planets supporting the even more intricate atomic arrangements making up minerals, plants,
and animals. Beneath all this compelling complexity lies an embarrassing fact — scientists do not know what most of the universe is made of. We only understand a small percentage of all the matter and energy in the cosmos. The greatest part of matter is a dark form of unknown identity, and even more abundant is a mysterious energy that exerts a repulsive force on space, inducing the universe to expand at an ever-increasing rate. Engineers have continually been at work on better, and cheaper, ways to search space for answers to these questions. New and improved telescopes, both on the ground and in space, make up part of the investigatory arsenal. Other devices measure waves of gravity rippling through space, or detect the fl ux of the elusive lightweight particle known as the neutrino. Whether these and other approaches can shed suffi cient light to disclose the universe’s darkest secrets remains unknown. It may be that further investigation of earthly materials will be needed as well, along with the continued assault on the problems of physics with the power of thought, an approach used so successfully by Einstein. Maybe answers will come only if scientists can succeed in discovering the ultimate laws of physics. In that regard, the underlying question is whether there exists, as Einstein believed, one single, ultimate underlying law that encompasses all physics in a unifi ed mathematical framework. Finding out may require new tools to unlock the secrets of matter and energy.
Perhaps engineers will be able to devise smaller, cheaper, but more powerful atom smashers, enabling physicists to explore realms beyond the reach of current technology. Another possible avenue to discovering a unifi ed law might be by achieving a deeper understanding of how the world’s tiniest and most basic building blocks work, the foundations of quantum physics. Engineers and physicists are already collaborating to develop computers based on quantum principles. Such computers, in addition to their possible practical value, may reveal new insights into the quantum world itself. All things considered, the frontiers of nature represent the grandest of challenges, for engineers, scientists, and society itself. Engineering’s success in fi nding answers to nature’s mysteries will not only advance the understanding of life and the cosmos, but also provide engineers with fantastic new prospects to apply in enterprises that enhance the joy of living and the vitality of human civilization.
