A physicist who has devoted his career to developing linear colliders confronts the decision that changed the global physics community and the focus of his work.
In 1998, theorists Lisa Randall and Raman Sundrum met in a coffee shop in Boston to discuss how extra dimensions of space would change the predictions of particle theories.
Deep in the Homestake Gold Mine in Lead, South Dakota, during the early 1970s, Ray Davis monitored a 100,000-gallon tank of perchloroethylene, a chlorine-rich dry-cleaning chemical.
Not only are neutrinos hard to catch, but they also change form as they travel through space. New experiments hope to understand their chameleonic nature.
Neutrinos are like no other particle in the universe. The more we learn about these "little neutral ones," the less we seem to understand them. Physicists do not even yet know what type of particle the neutrino is.
As spring arrived, so did the kids. Their knees wobbly and eyes wide open, they stayed close to their moms. Dad, weighing more than 2500 pounds, made sure that no harm came the babies' way.
