The weak force is responsible for the decay of matter: unstable particles made of heavy quarks and antiquarks decay into particles made of their lighter cousins.
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.
Artist Robert Lang has folded intricate paper sculptures from flat sheets that, in some cases, started out over nine feet long. He uses the same method many of us used to make cranes and party hats in elementary schoola series of precise folds. But Langs designs are far more complex.
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.
