The Sesame institute is made up of physicists from several countries that rarely talk to one another but whose scientists are determined to collaborate.
Whether climbing trees with her eight-year-old son Isaac, trying to put a dress on her four-year-old daughter Sonia, or running tests on the MINOS neutrino beam line, Debbie Harris is a problem solver and her mind is always busy. "It's really hard to be a parent," she says.
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.
As the sun rises each day, warming the grounds and buildings of the Stanford Linear Accelerator Center, the entire SPEAR3 synchrotron facility expands in response.
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.
