In Brief

Fermilab Users Meeting registration now open

The 2015 Fermilab Users Meeting takes place from June 10-11. Registration is now open.

Registration for the 48th annual Fermilab Users Meeting is now open. The meeting will take place from June 10-11, with the Festa Italiana taking place on the evening of June 9.

Topics to be covered at the Users Meeting include collider, astroparticle, neutrino, muon and accelerator physics, as well as future plans.

The New Perspectives conference, organized by the Fermilab Student and Postdoc Association, will be held before the Users Meeting, from June 8-9.

This year at the meeting, the American Physical Society will recognize the bottom and top quark discoveries at Fermilab by naming Fermilab a historic site.

The meeting will also feature a public lecture on June 10 by Francis Halzen of the University of Wisconsin–Madison. Tickets to the talk are now on sale.

The deadline for registration is June 1. For more information, visit the Users Meeting Web page. You can also view the draft meeting agenda.


Fermilab Arts and Lecture Series presents Hot Club of Cowtown - Saturday at 8 p.m.

Hot Club of Cowtown performs Saturday at 8 p.m. in Ramsey Auditorium.

Since its beginnings in the late 1990s, Hot Club of Cowtown's star has continued to rise as its reputation for virtuosity and unforgettable live shows has become the band's global brand.

The Fermilab Arts and Lecture Series presents Hot Club of Cowtown on Saturday, May 2, at 8 p.m. in Ramsey Auditorium.

The band's musical alchemy has been described as "another breathless journey in the Texas trades." The Hot Club has a dedicated cult following worldwide. They have toured with Bob Dylan and opened seven nights of Roxy Music's sold-out "For Your Pleasure" U.K. stadium tour in early 2011.

Tickets are $25, $13 for ages 18 and under. For more information or to make reservations, visit the Fermilab Arts Series Web page or call 630-840-2787.

Biggest dark matter detector lies in wait for antisocial WIMPs

From New Scientist, April 23, 2015

I feel a rush in my stomach as the cage drops and the pressure on my eardrums increases. I am travelling 2 kilometers underground in a metal box that will carry me to the front line in the search for dark matter. I am eager to see DEAP, the world's most sensitive detector before it is sealed off forever — but right now I wish I could stay at sea level.

My guide, Jack Dunger from the University of Oxford, reassures me. "The cage is much scarier than the tunnel," he says. "Once you are down there you will feel more normal."

A long look at Earth Day

As I write this, it is April 22, Earth Day. Each year at Fermilab, we celebrate this day with nature programs, tree plantings and, more recently, the Earth Day Fair in Wilson Hall. But what is it we are celebrating?

The original Earth Day, the conception of then Senator Gaylord Nelson, was to be a national "teach-in" — a day for citizens to learn about and advocate for the environment. The environment in 1970 was in serious peril. Municipalities and industry routinely discharged untreated waste into rivers and lakes, and chimneys poured pollution into the air to return as acid rain. Secondly, it was an era of protest: against the war in Vietnam, racism, sexism and society in general, including the deterioration of the environment.

Earth Day 1970 is widely cited as the beginning of the environmental movement. With the passage of epic legislation by Congress during the 1970s to protect air, water, wildlife and responsibly manage hazardous chemicals, the overall condition of the environment began to turn around in dramatic fashion. The air in industrial cities such as Pittsburgh and Cincinnati became breathable, some rare species received legal protection, and the Cuyahoga River in Cleveland no longer caught fire. That's the good news.

Challenges remain, however. Cleaning up the water and air was relatively easy, what we often call the low-hanging fruit. Since the 1970s, new and less tractable environmental issues have arisen. Many of these 21st-century problems are harder to approach because they are less immediate than dirty air and water. Habitat destruction, especially on other continents, ozone depletion and climate change resulting from increases in greenhouse gases are difficult for the average person to visualize on an average day.

The activism and legislation of the 1970s produced tangible results, but it also ushered in a paradigm shift of sorts. Government, business and urban planners have slowly begun to incorporate environmental factors into their thought processes. "Sustainability" has become an all-encompassing concept that integrates various environmental as well as human welfare issues. For us at Fermilab, the federal push for sustainability forces us to examine our use of resources, generation of greenhouse gases and human health.

Earth Day is, and should be, a celebration. At Fermilab, we have a proud history of environmental awareness, land stewardship and responsible policies. We now have a Sustainability Committee that includes members from all laboratory organizations, and each year we publish our Site Sustainability Plan. But the celebration should also remind all of us that there is still much to be done before we reach a truly sustainable society at multiple levels. If you have an idea about how to make Fermilab more sustainable, email me with your suggestion.

Wormholes untangle a black hole paradox

From Quanta Magazine, April 24, 2015

One hundred years after Albert Einstein developed his general theory of relativity, physicists are still stuck with perhaps the biggest incompatibility problem in the universe. The smoothly warped space-time landscape that Einstein described is like a painting by Salvador Dalí — seamless, unbroken, geometric. But the quantum particles that occupy this space are more like something from Georges Seurat: pointillist, discrete, described by probabilities. At their core, the two descriptions contradict each other. Yet a bold new strain of thinking suggests that quantum correlations between specks of impressionist paint actually create not just Dalí's landscape, but the canvases that both sit on, as well as the three-dimensional space around them. And Einstein, as he so often does, sits right in the center of it all, still turning things upside-down from beyond the grave.
