2015 Fermilab Photowalk: winning images

Mike Baker of Bolingbrook, Illinois, took first place with this photo of the bubble chamber by the Geodesic Dome.
The second-place photo was also submitted by Mike Baker, Bolingbrook, Illinois.
Nelson Mark of Middletown, Indiana, submitted the third-place photo.

You are viewing winners of the recent 2015 Fermilab Photowalk competition. These three finalists will be entered into an international competition organized by

View the Fermilab finalists and the honorable mentions on the Fermilab Photowalk Web page. Read more about the global competition.

On Sept. 26, Fermilab invited 50 photographers into five areas of the lab that are not normally part of the public tour. The photographers were then asked to submit their best pictures, and a panel of local judges selected their favorites.

Will quantum mechanics swallow relativity?

From Nautilus, Oct. 29, 2015

It is the biggest of problems, it is the smallest of problems.

At present physicists have two separate rulebooks explaining how nature works. There is general relativity, which beautifully accounts for gravity and all of the things it dominates: orbiting planets, colliding galaxies, the dynamics of the expanding universe as a whole. That's big. Then there is quantum mechanics, which handles the other three forces — electromagnetism and the two nuclear forces. Quantum theory is extremely adept at describing what happens when a uranium atom decays, or when individual particles of light hit a solar cell. That's small.

Workshop on Booster accelerator performance and enhancements - Nov. 23-24

The Proton Improvement Plan Group will host the Workshop on Booster Performance and Enhancement from Nov. 23-24 in Wilson Hall.

This workshop will bring together machine experts, collaborators, users, collegial experts and interested members of the Fermilab community to confer with Fermilab accelerator physicists and experts. Attendees will critically assess issues related to the intensity and performance of the Fermilab Booster synchrotron and comparable accelerators elsewhere.

To register or learn more about the workshop, visit the workshop Indico site.

If you have any questions, please contact one of the workshop organizers, Bill Pellico, Bob Zwaska or Cheng-Yang Tan.

Gravitational waves and where to find them

Advanced LIGO has just begun its search for gravitational waves.

For thousands of years, astronomy was the province of visible light, that narrow band of colors the human eye can see.

In the 20th century, astronomers pushed into other kinds of light, from radio waves to infrared light to gamma rays. Researchers built neutrino detectors and cosmic ray observatories to study the universe using particles instead. Most recently, another branch of lightless astronomy has been making strides: gravitational wave astronomy.

It's easy to make gravitational waves: Just flap your arms. Earth's orbit produces more powerful gravitational waves, but even these are too small to have a measurable effect. This is a good thing: Gravitational waves carry energy, and losing too much energy would cause Earth to spiral into the sun.

Gravitational waves are an important prediction of Einstein's general theory of relativity. According to that theory, a variety of astronomical objects—such as supernova explosions, pairs of black holes and other mutually orbiting objects with strong gravity—give off energy as disturbances in the structure of space-time that propagate outward at the speed of light.

Even though these waves are ubiquitous and often carry enormous amounts of energy, gravity is so weak that they barely nudge other objects as they pass.

But sufficiently sensitive detectors could measure these waves.

Safety Update

ESH&Q weekly report, Nov. 2

This week's safety report, compiled by the Fermilab ESH&Q Section, contains one incident.

An employee dropped the Exacto knife he was using to cut the outer jacket of a type SO cord. He reflexively reached to catch it and cut his left thumb. He received first aid.

See the full report.

Searching the invisible

From Nature, Nov. 3, 2015

By particle-physics standards, the Kamioka site is a rather small laboratory, hidden away in the mountains of the Gifu prefecture in Japan. Nevertheless, it has come to be seen as something of a legendary place by physicists and science aficionados in Japan. One of its experiments, the Super-Kamiokande, is even reproduced as a 1/10 scale model in Miraikan, the National Museum of Emerging Science and Innovation, in Tokyo. And few Japanese aren't aware of Masatoshi Koshiba, and more recently Takaaki Kajita, the recipients of the 2002 and 2015 Nobel prizes in physics. Although the discovery of neutrinos and their oscillations is one of the more fascinating stories in the history of science, the Kamioka site itself has its own captivating history.
