Electric Sky, Traffic Light Design, and Other Reasons for Paying Attention

This article was published in Scientific American’s former blog network and reflects the views of the author, not necessarily those of Scientific American


The world is trying to remind you to keep your eyes open, to take nothing for granted. Don't ignore the quotidian: look there for breakthroughs.

Consider the electric sky created by a German electric engineering firm to mimic the changing cloudscape of life under the real blue sky. The idea is to improve workers' senses of well-being by making them feel like they are outside, according to a piece in Wired.co.uk. Each ceiling tile is 50cm square and uses 288 LEDs to make the obligatory millions of colors in the full light spectrum. A diffuser grating -- remember the old speaker-cabinet-filled-with-Christmas-lights shop project? -- gives the whole thing that gauzy, cloudy effect.

In the Wired article, Dr. Matthias Bues says the fluctuating colors "promote concentration and heighten alertness." Volunteers who spent time under the panels when they fluctuated slowly, fluctuated rapidly, or remained unchanging preferred the rapid fluctuations, which appear to be most like the real outdoors.

When you really are outdoors, pay attention to something as simple as your traffic signals. This article on Weburbanist.com surveys some awesome new designs that enable signals to give you more information -- for example, through hourglasses, countdowns, shapes, or clockfaces -- preventing frustration and smoothing flow by letting you know how long you'll be waiting. Shaped lights help the colorblind, too. You didn't know how much more you could be getting from your traffic signal until you paid some attention, yes?

Finally, for general attention paying, check out The Spotter's Guide to Urban Engineering,a new book that falls somewhere between the pocket-handy Field Guide to Roadside Technology and the irreplaceable but unwieldy Infrastructure: The Book of Evertything for the Industrial Landscape. The Spotter's Guide is sort of the bathroom book that goes between the pocket Field Guide and the encyclopedic Infrastructure. Too big for your pocket yet not overwhelmingly thorough, it's a great place to dip -- how do canal locks work? the world's most complicated roundabout? a movable bridge that curls instead of lifting or rotating? It's all here.

Now pay attention.

Scott Huler was born in 1959 in Cleveland and raised in that city's eastern suburbs. He graduated from Washington University in 1981; he was made a member of Phi Beta Kappa because of the breadth of his studies, and that breadth has been a signature of his writing work. He has written on everything from the death penalty to bikini waxing, from NASCAR racing to the stealth bomber, for such newspapers as the New York Times, the Washington Post, the Philadelphia Inquirer, and the Los Angeles Times and such magazines as ESPN, Backpacker, and Fortune. His award-winning radio work has been heard on "All Things Considered" and "Day to Day" on National Public Radio and on "Marketplace" and "Splendid Table" on American Public Media. He has been a staff writer for the Philadelphia Daily News and the Raleigh News & Observer and a staff reporter and producer for Nashville Public Radio. He was the founding and managing editor of the Nashville City Paper. He has taught at such colleges as Berry College and the University of North Carolina at Chapel Hill.

His books include Defining the Wind, about the Beaufort Scale of wind force, and No-Man's Lands, about retracing the journey of Odysseus.

His most recent book, On the Grid, was his sixth. His work has been included in such compilations as Appalachian Adventure and in such anthologies as Literary Trails of the North Carolina Piedmont, The Appalachian Trail Reader and Speed: Stories of Survival from Behind the Wheel.

For 2014-2015 Scott is a Knight Science Journalism Fellow at MIT, which is funding his work on the Lawson Trek, an effort to retrace the journey of explorer John Lawson through the Carolinas in 1700-1701.

He lives in Raleigh, North Carolina, with his wife, the writer June Spence, and their two sons.
