| First, our world: the entire occupancy of this planet, as far as we can tell, is constrained to a thin surface layer of the earth—the peel of our potato—throughout which we space our skyscrapers and stadiums, our mansions, apartments, and igloos, our aircraft and submarines, our tour buses and rickshaws, our cruise ships and dinghies. The thickness of this shell is barely more than a thousandth of the earth's width across, yet it contains virtually all of life that we know about, all manner of microbes, algae, insects, daffodils, vermin, fowl, people, elephants, trees, and whales, not to mention the mountains and oceans! So, if we imagine a gigantic, alien potato peeler, poised to scrape off the usual amount of skin to make some global fries, all that we know would be taken off with the peel (except, perhaps, a few adventurous souls on the space station and a bit of other space paraphernalia).
Far from making global fries, we have not even been able to reach into our potato planet to any significant depth at all. Yet we have managed to land on our moon, a smallish cherry tomato that orbits our spud a half-room away—a tenuous connection to another world, but real nonetheless. In this picture, Apollo 13 would be smaller than a red blood cell! When I think about it, travelling essentially without power across that room along gravitational stream lines, around the cherry tomato and back again to the potato, and through the top layer of that skin, it fills me with some serious awe.
"Connecting Worlds" in a literal sense is difficult but . . . well, awesome. Of course, though, the Physics Congress planners are thinking figuratively, too: worlds of public service, worlds of different cultures, and worlds of new technologies, for example. The lineup of speakers is truly amazing—from Jocelyn Bell Burnell, co-discoverer of pulsars, astronaut John Grunsfeld, and Nobel Prize winner John Mather, to author Freeman Dyson, exoplanet pioneer John Johnson, and binary star expert Mercedes Richards—and is filled with scientists who have really shown how to serve society and connect the uninitiated with their cutting-edge science. In some ways, though, the heart of the Congress is the sequence of workshops in which participants discuss and debate the future directions of the societies (SPS and Sigma Pi Sigma) after hearing from scientists in the trenches. Topics like Connecting Scientists and Science Policy, Connecting Science and Technology, Connecting Students and Careers, and Connecting Physics and the Public are sure to engage the participants and provide actionable outcomes. Bookending the Congress will be tours of the Kennedy Space Center and an art competition, rounding out the experience and better connecting the left and right brain worlds, if yours were ever feeling disconnected.
So, consider connecting your disjoint worlds, be they spud-like or not, and join Sigma Pi Sigma at the Physics Congress. Registration begins in May, and you can check out further details on the conference website, http://www.spscongress.org/.

One week later, the team also supported The Optical Society by helping to promote the cutting-edge research presented at the Optical Fiber Communication Conference and Exposition/National Fiber Optic Engineers Conference (OFC/NFOEC), which was held March 4–8 at the Los Angeles Convention Center. This conference covered topics of interest in telecommunications, optical networks, data communications, and more. Of particular interest were two presentations: a new graphene-based optical modulator that is poised to help break current data speed records and an equally record-setting wireless data bridge, which took communications that important "last mile."
A hearing in the House Committee on Science, Space, and Technology addressed the challenges and opportunities associated with the International Space Station, and a hearing in the House Energy and Commerce Committee addressed what can be done regarding rising gas prices. American competitiveness was the ongoing topic of numerous discussions in the Senate as well as the House of Representatives.
The Government Relations team summarizes these and other hearings in FYI: The AIP Bulletin of Science Policy News. Staff also met with members of Congress to discuss the importance of sustained science funding during this climate of tightened budgets.
|Physics Today, April 2012 issue. Cover—The human brain consists of nearly 1011 neurons and some 104 times that number of connections, organized into a complex network of local circuits and long-range fiber pathways. The diffusion spectrum image shown here reveals part of that web: The threadlike structures are nerve bundles, each containing thousands of nerve fibers. The brain is just one of countless networks whose behavior scientists seek to understand. For details on their properties and often counterintuitive dynamics, refer to the article by Adilson Motter and Réka Albert on page 43.
