The experiment's third and final result, based on the last three years of data, is in perfect agreement with previous results ...

With big outstanding questions and little hints of new physics, physicists are now rethinking some of their most fundamental assumptions. For centuries, scientists thought the universe was filled with ...

A large and unexpected excess of top quark pairs has the physics community excited, but the interpretation is still up for debate. In 1995, Alexander Grohsjean cut out a story from the local German ...

The LHCb experiment at CERN has revealed a fundamental asymmetry in the behavior of particles called baryons. “The reason why it took longer to observe CP violation in baryons than in mesons is down ...

Don’t know your convolutional neural networks from your boosted decision trees? Symmetry is here to help. It’s time for some deep learning. Check out this list to pick up some new terminology—and ...

The US physics community dreams of building a muon collider. In the spring of 2022, Karri DiPetrillo was gearing up for the final step of the Snowmass particle physics community planning process. It ...

A professor at the University of Tennessee reimagines the way we teach STEM with a science-fiction story-based class. In the beginning, a spaceship called the Yggdrasil is sailing through the cosmos ...

In the 1900s, Albert Einstein unified the concepts of space and time, giving us a useful new way to picture the universe. At the start of the 20th century, physicists had a problem: The speed of light ...

The Higgs boson is the only fundamental particle known to be scalar, meaning it has no quantum spin. This fact answers questions about our universe, but it also raises new ones. When it was first ...

For decades scientists have tried to find a way to measure the mass of the lightest matter particle known to exist. Three new approaches now have a chance to succeed. In 1980, Hamish Robertson was a ...

Symmetry chats with scientists and engineers about doing important work in physics without a doctoral degree. Ronald Richards’ father was a mechanical engineer for Ford Motor Co., and as a child in ...
