Symmetry features

Missing visits to the museum? Or in need of some home-school activities? Check out these five do-it-yourself physics demos from Ketevan Akhobadze, an exhibit developer for the Lederman Science Center at Fermilab.

Symmetry writer Sarah Charley answers life and relationship questions through the lens of fundamental physics. Instead of using analogies from elsewhere in life to explain science, she’ll use physics analogies to explore human nature. This time, she tackles unwanted gifts, when to give up on a dream and how friendships might be like Newtonian mechanics.

Later this decade, the Large Hadron Collider will be upgraded to the High-Luminosity LHC. What does “luminosity” mean in particle physics, and why measure it instead of collisions?

Organizers of the planning exercise that helps shape the future of U.S. particle physics have moved its final workshop back by one year.

Once the most popular framework for physics beyond the Standard Model, supersymmetry is facing a reckoning — but many researchers are not giving up on it yet.

Workshops around the world train science teachers to incorporate particle physics into their classrooms.

Until recently, scientists had never detected black holes in the “mass gap.” Now, particle physicists are exploring ideas beyond the Standard Model that could explain them.

How do the questions Galileo faced in the 17th century relate to those posed in our own era? What is our place in this vast realm of existence? How will spacetime come to an end?Symmetry writer Mike Perricone’s favorite physics books of 2020 cover an impressive span of time: from the very beginning of our universe until the very end.

Next week, scientists with connections to U.S. particle physics will make their morning coffee, boot up their computers and log in to a virtual community planning meeting with over 1,500 colleagues. The four-day gathering will set the stage for a process known as Snowmass, during which scientists will develop a collective vision for the next decade of U.S. particle physics research. The Snowmass process seeks to identify the most promising questions to explore in future research.

Handedness — and the related concept of chirality — are double-sided ways of understanding how matter breaks symmetries. Different-handed object pairs reveal some puzzling asymmetries in the way our universe works.
