Although we now think of the universe as three bulky, nearly-flat dimensions, we might soon discover that the fabric of space-time consists of many more dimensions than we ever dreamed.
Nature provides three kinds of neutrinos. In the last ten years, physicists have gathered increasingly strong evidence for neutrino oscillations, the transformation of one kind of neutrino into another one.
Today's cutting-edge scientific projects are larger, more complex, and more expensive than ever. Grid computing provides the resources that allow researchers to share knowledge, data, and computer processing power across boundaries.
A piece of steel may look cold and lifeless. But like any other piece of matter, it is bursting with activity deep inside. Electrons whiz around inside atoms, and a sea of never-resting quarks and gluons populates the nucleons that make up the atomic core.
