Symmetry features

Imagine a particle. What comes to mind? If you aren’t a theoretical particle physicist, chances are you picture a tiny ball, bobbing in space. But that’s not quite correct. One way to prove it: Try to imagine that tiny ball as a particle with no mass. If a particle has no mass, how can it exist?

Right now could be considered one of the best — and most uncertain — times in theoretical physics. That’s what Symmetry heard in interviews with 10 junior faculty in the field. They talk about what keeps them up at night, their favorite places to think and how they explain their jobs to nonscientists.

Particle accelerators are some of the most complicated machines in science. In today’s more autonomous era of self-driving cars and vacuuming robots, efforts are going strong to automate different aspects of the operation of accelerators, and the next generation of particle accelerators promises to be more automated than ever. Scientists are working on ways to run them with a diminishing amount of direction from humans.

Word fans, rejoice! Symmetry is back with another list of 10 common words that take on a new meaning when spoken by scientists. Take these physics words for a spin.

Physicists meet this week in Granada, Spain, to update the European Strategy for Particle Physics. Hundreds of scientists from around the globe associated with the European particle physics program are meeting ti discuss and evaluate what Europe’s next collaborative projects should be. The end goal is a consolidated strategy that European research institutions can use to guide their efforts for the next several years.

In their quest to discover physics beyond the Standard Model, physicists weigh the pros and cons of different search strategies.

By developing clever theories and conducting experiments with particle colliders, telescopes and satellites, physicists have been able to wind the film of the universe back billions of years—and glimpse the details of the very first moments in the history of our cosmic home. Take a (brief) journey through the early history of our cosmos.

Building a particle physics laboratory requires more than physicists. Fermilab archivist Valerie Higgins has authored a paper available in the online physics repository arXiv, and earlier this month she published an op-ed for Physics World on the importance of capturing perspectives from all parts of the laboratory. She sat down with Symmetry writer Lauren Biron to discuss her thoughts.

Respondents to Symmetry’s survey about what it’s like to earn a Ph.D. in particle physics or astrophysics offer their views of the experience. Nearly 2,000 people worldwide complete the scientific rite of passage each year. Yet for many people, the process remains mysterious.
The more than 300 responses to Symmetry’s survey described a challenging, multifaceted experience that goes far beyond job training, and even beyond the scientific goal of studying the fundamental nature of the universe.
