They sent us cutting templates, which were pieces of 3D modeling that we were able to place on the child’s skull during surgery

Both Egnor and Duboys said the 3D modeling technology helped to cut down on the length of the procedure, which meant Gabriel spent far less time under anesthesia than during traditional surgery

The project is among the most ambitious in the growing field of three-dimensional printing that some say could revolutionize medicine.

In a world where knowledge is revered and innovation equals progress, those able to bring forth greater insight and understanding are destined to make their mark and blaze a trail to greater enlightenment. "Critical thinking as an attitude is embedded in Western culture. There is a belief that argument is the way to finding truth," observes Adrian West, research director at the Edward de Bono Foundation U.K., and a former computer science lecturer at the University of Manchester. "Developing our abilities to think more clearly, richly, fully—individually and collectively—is absolutely crucial [to solving world problems]." To be sure, history is filled with tales of remarkable thinkers who have defined and redefined our world views: Sir Isaac Newton discovering gravity; Voltaire altering perceptions about society and religious dogma; and Albert Einstein redefining the view of the universe. But in an age of computers, video games, and the Internet, there's a growing question about how technology is changing critical thinking and whether society benefits from it. Although there's little debate that computer technology complements—and often enhances—the human mind in the quest to store information and process an ever-growing tangle of bits and bytes, there's increasing concern that the same technology is changing the way we approach complex problems and conundrums, and making it more difficult to really think. "We're exposed to [greater amounts of] poor yet charismatic thinking, the fads of intellectual fashion, opinion, and mere assertion," says West. "The wealth of communications and information can easily overwhelm our reasoning abilities." What's more, it's ironic that ever-growing piles of data and information do not equate to greater knowledge and better decision-making. What's remarkable, West says, is just "how little this has affected the quality of our thinking." According to the National Endowment for the Arts, literary reading declined 10 percentage points from 1982 to 2002 and the rate of decline is accelerating. Many, including Patricia Greenfield, a UCLA distinguished professor of psychology and director of the Children's Digital Media Center, Los Angeles, believe that a greater focus on visual media exacts a toll. "A drop-off in reading has possibly contributed to a decline in critical thinking," she says. "There is a greater emphasis on real-time media and multitasking rather than focusing on a single thing." Nevertheless, the verdict isn't in and a definitive answer about how technology affects critical thinking is not yet available. Instead, critical thinking lands in a mushy swamp somewhere between perception and reality; measurable and incomprehensible. It's largely a product of our own invention—and a subjective one at that. And although technology alters the way we see, hear, and assimilate our world—the act of thinking remains decidedly human. Back to Top Rethinking Thinking Arriving at a clear definition for critical thinking is a bit tricky. Wikipedia describes it as "purposeful and reflective judgment about what to believe or what to do in response to observations, experience, verbal or written expressions, or arguments." Overlay technology and that's where things get complex. "We can do the same critical-reasoning operations without technology as we can with it—just at different speeds and with different ease," West says. What's more, while it's tempting to view computers, video games, and the Internet in a monolithic good or bad way, the reality is that they may be both good and bad, and different technologies, systems, and uses yield entirely different results. For example, a computer game may promote critical thinking or diminish it. Reading on the Internet may ratchet up one's ability to analyze while chasing an endless array of hyperlinks may undercut deeper thought.

Closer to home, private industries like Mars One seek to establish a permanent settlement on the Red Planet. At the Smithsonian Magazine's "The Future is Here Festival" in Washington, D.C. this month, former astronaut Mae Jemison and NASA engineer Adam Steltzner spoke optimistically about the future of manned space exploration

Although the idea that bacteria — and life — could hitch a ride on traveling rocks to spread life to other planets is not new, Steltzner suggested a deliberate program that sounds more like science fiction than science fact. Such bacteria could carry our genome and the instructions to reassemble it after landing on a planet (and, one assumes, after the planet has been terraformed to support such life). Steltzner described the process as "printing human beings organically over time."

In addition to curiosity-motivated exploration, Steltzner pointed out that as long as humans remain on a single planet, we are at risk of extinction when disaster strikes. "Our real estate portfolio suffers from a concentration of risk," he said.
