Workshops around the world train science teachers to incorporate particle physics into their classrooms. Picture this: A stationary object such as a vase suddenly explodes, sending fragments flying.

Particle accelerators reveal the heart of nuclear matter by smashing together atoms at close to the speed of light. The high-energy collisions produce a shower of subatomic fragments that scientists ...

Scientists who moved from particle physics or astrophysics to medical physics sit down with Symmetry to talk about life, science and career changes. “I wasn’t one of those people who grew up knowing ...

At every moment, subatomic particles stream in unfathomable numbers through your body. Each second, about 100 billion neutrinos from the sun pass through your thumbnail, and you’re bathed in a rain of ...
