What's up in
The KATRIN experiment is closing in on the mass of the neutrino, which could point to new laws of particle physics and shape theories of cosmology.
The theoretical particle physicist Ann Nelson, who died on August 4 at age 61, was a font of brilliant ideas and a champion of ending discrimination in the field.
Carlo Rubbia, leader of the bold collider experiment that in 1983 discovered the W and Z bosons, thinks particle physicists should now smash muons together in an innovative “Higgs factory.”
Lurking behind Einstein’s theory of gravity and our modern understanding of particle physics is the deceptively simple idea of symmetry. But physicists are beginning to question whether focusing on symmetry is still as productive as it once was.
In the hunt for new fundamental particles, physicists have always had to make assumptions about how the particles will behave. New machine learning algorithms don’t.
New findings are fueling an old suspicion that fundamental particles and forces spring from strange eight-part numbers called “octonions.”
