One sprinkle of sand at a time, two artists have recreated the moment a particle passed through a detector 30 years earlier. Their piece, a bright blue and white sculpture of tracks of microscopic bubbles in a bubble chamber, was inspired by the Tibetan Buddhist tradition of the sand mandala. To find the perfect bubble chamber image to recreate, they scrolled through hundreds of these photographs in the archive at Fermilab.
The Large Synoptic Survey Telescope will manage unprecedented volumes of data produced each night. Scheduled to come online in the early 2020s, the LSST will use a 3.2-gigapixel camera to photograph a giant swath of the heavens. It’ll keep it up for 10 years, every night with a clear sky, creating the world’s largest astronomical stop-motion movie.
With the warmth of holiday cheer in the air, some physicists decided to hit the pub after a conference in December 2014 and do what many physicists tend to do after work: keep talking about physics. That evening’s topic of conversation: dark energy particles. The chat would lead to a new line of investigation at the Large Hadron Collider at CERN. Every second, the universe grows a little bigger. Scientists are using the LHC to try to find out why.
If one wanted to follow the recipe for the universe, it would call for about 14 parts dark energy, 5 parts dark matter and 1 part visible matter. In a perpetually expanding cosmic landscape that reaches far beyond what even the most powerful telescopes can see, this might be hard to visualize. Physicists Katy Grimm and Katharine Leney found a solution for this: Use this recipe for the cosmos to bake a proportionally correct dark matter cake.
Fermilab’s Liz Sexton-Kennedy talks to Symmetry about her lifelong drive to learn and how it led to her current role as chief information officer for Fermilab. Jim Daley spoke to Sexton-Kennedy about her experiences in STEM, her career at Fermilab and a bit about herself.
Physicists often find thrifty, ingenious ways to reuse equipment and resources. What do you do about an 800-ton magnet originally used to discover new particles? Send it off on a months-long journey via truck, train and ship halfway across the world to detect oscillating particles called neutrinos, of course. It’s all part of the vast recycling network of the physics community.
A new telescope will take a sequence of snapshots with the world’s largest digital camera, covering the entire visible night sky every few days — and repeating the process for an entire decade. What’s the best way to rapidly and automatically identify and categorize all of the stars, galaxies and other objects captured in these images? Data scientists trained have computers to pick out useful information from these hi-res snapshots of the universe.
A pair of 1964 films detailing the construction of Stanford Linear Accelerator Center were recently remastered and are now available for viewing on YouTube. The films provide a fascinating look back at the origins of SLAC and the history of particle physics in the United States. At the time of the production, SLAC was the largest civilian basic science project ever undertaken in the United States.
If you want to visit the Pasner family farm, you’ll need a truck with four-wheel drive. You’ll need to traverse 4 miles of bumpy dirt road deep into the countryside of Penn Valley, California. But once you arrive, you’ll be greeted by fields of organic onions and garlic, nestled between rolling grassy hills speckled with oak trees. For physicist Jake Pasner, this will always be home.
Fermilab’s Inclusivity Journal Club seeks answers to difficult social questions in science. A typical meeting includes physicists and postdoctoral researchers as well as non-science staff; students are also welcome to attend. Members read and discuss reports and peer-reviewed papers that address issues such as sexual harassment, implicit bias and best practices for expanding inclusivity.
