New members of Users Executive Committee elected

Fermilab welcomes the newest members of the Users Executive Committee: Fernanda Garcia (Fermilab), Fabio Happacher (INFN Frascati), William Louis (Los Alamos National Laboratory), Jesus Orduna (Rice University), Linda Spentzouris (Illinois Institute of Technology) and Thomas Strauss (University of Bern).

The new members will serve a two-year term and will join continuing members Sandra Biedron (Colorado State University), Tulika Bose (Boston University), Andre de Gouvea (Northwestern University), Bill Lee (Fermilab), Vivian O'Dell (Fermilab), Marcelle Soares-Santos (Fermilab) and Lee Roberts (Boston University, current UEC chair) in the first year. Rotating off the committee at this time are Mary Anne Cummings (Muons Inc.), Craig Group (University of Virginia and Fermilab), Breese Quinn (University of Mississippi), Mandy Rominsky (Fermilab), Greg Snow (University of Nebraska) and Nikos Varelas (University of Illinois at Chicago). A new UEC chair will be elected by the committee at its first meeting on Sept. 26.

Got a minute? Turning collisions into numbers

It might be obvious, but a crucial step in understanding our universe is to take physical properties, for instance energy and position, and to quantify them. Once the results have been quantified, we can then turn to powerful mathematical tools to better understand what is going on. Scientist Titas Roy helps us understand this better. View the video.

All Experimenter Meetings during six-week shutdown

The All Experimenter Meetings will take place every other Monday at 4 p.m. during the accelerator shutdown for maintenance and upgrades. The next AEM will take place on Sept. 22. The seminar will return to the normal weekly cycle towards the end of October, after the shutdown.

Butterfly birth

From caterpillar to butterfly. The monarch butterfly chrysalis is green until the evening before the butterfly emerges, when it seems to turn black. In reality the chrysalis is becoming clear like glass, and the perceived black is the wings of the butterfly itself. This shows the chrysalis just moments before the butterfly emerges. Its wings are folded up inside the clear chrysalis. Photo: Gregory Cisko, CCD
The butterfly emerges from the chrysalis, wings still folded. It will still be several hours before the butterfly is ready to fly. Photo: Gregory Cisko, CCD
This is one of four monarchs that the photographer released several hours after it emerged from its chrysalis and just before it took off and started flying for the first time. The butterflies were released near the flowers by the Ramsey Auditorium entrance. Photo: Gregory Cisko, CCD

National labs play unique role in working for America

From The Hill, Sept. 9, 2014

In the last decade, our nation's energy supply has been radically transformed by technologies to harness shale gas and unconventional oil. The advancement of inexpensive renewables is now poised to improve the energy mix even further. Since the end of the Cold War, the global use of nuclear material has been contained without incident, while emerging security challenges are being met head on with novel technologies. Millions today are alive because of drugs that the pharmaceutical industry can design with molecular precision, while a revolution in personalized medicine is under way as a result of inexpensive and rapid genomic testing.

In each of these developments, the U.S. Department of Energy's National Laboratory System has played a unique and decisive role — a fact unknown to most Americans.

Physics in a Nutshell

Epic facepalm

A recent statement by physicist Stephen Hawking has been misrepresented in the extreme. Let's take a look at what he really meant.

Read the full column on stability and the Higgs boson.

If you're a science enthusiast, this week you have likely encountered outlandish headlines invoking Stephen Hawking, the Higgs boson and the end of the universe. I hope you had the presence of mind to react as the famous actor in the picture did. Let's start with the answer first. The universe is safe and will be for a very long time — for trillions of years. This story as widely reported by the media is a jaw-dropping misrepresentation of science.

To understand how abominably Hawking's statement was twisted, first we need to understand the statement. To paraphrase just a little, Hawking said that in a world in which the Higgs boson and the top quark have the masses that scientists have measured, the universe is in a metastable state.

So let's take those pieces one at a time. What does "metastable" mean? Basically, metastable means "kind of stable." So what does that mean? Let's consider an example. Take a pool cue and lay it on the pool table. The cue is stable; it's not going anywhere. Take the same cue and balance it on your finger. That's unstable; under almost any circumstances, the cue will fall over. So the terms stable and unstable are easy and have familiar, real-world analogues. The analogy for a metastable object is a barstool. Under almost all circumstances, the stool will sit there for all eternity. However, if you bump the stool hard enough, it will fall over. When the stool has fallen over, it is now more stable than it was, just like the pool cue lying on the table.

Now we need to bring in the universe and the laws that govern it. Here is an important guiding principle: The universe is lazy — a giant, cosmic couch potato. If at all possible, the universe will figure out a way to move to the lowest energy state it can. A simple analogy is a ball placed on the side of a mountain. It will roll down the mountainside and come to rest at the bottom of the valley. This ball would then be in a stable configuration. The universe is the same way. After the cosmos was created, the fields that make up the universe should arrange themselves into the lowest possible energy state.

There is a proviso. Just as on a slope of a mountain, where there may be a little valley part way up the hill (above the real valley), it is possible that there could be little "valleys" in the energy slope. As the universe cooled, it could be that it might have been caught in one of those little valleys. Ideally, the universe would like to fall into the deeper valley below, but it could be trapped. This is an example of a metastable state. As long as the little valley is deep enough, it's hard to get out of. Indeed, using classical physics, it is impossible to get out of it.
