The many lives of Fermi's magnet

If this magnet could talk, you'd hear some amazing stories. During its half-century career, this four-million-pound magnet contributed to experiments that changed our view of physics while serving some of the field's foremost experimenters, including Enrico Fermi.

Lylie Fisher: Beauty bubbles through

For artist Lylie Fisher, particle physics is much more than a field of science. It is art: "Like art, particle physics deals with the invisible," says Fisher. "One portrays emotional and spiritual experiences; the other studies unseen matter and energy.
