Quantum Point Contacts

The quantization of ballistic electron transport through a constriction demonstrates that "conduction is transmission" -- Henk van Houten and Carlo Beenakker

Solar Neutrino Experiments: The Next Generation

Three big new detectors are addressing the puzzle of the persistent solar-neutrino deficit. Is it the Sun, or the neutrino, that's behaving so strangely? We may soon know for certain -- John N. Bahcall, Frank Calaprice, Arthur B. McDonald and Yoji Totsuka

Making a Difference: Ethnic Diversity in Physics

If we are to overcome the major obstacles to science education for all, it will require the dedicated efforts of the entire science community -- James H. Stith

Search and Discovery

Galileo's probe sends a weather report from Jupiter. The first-ever in situ measurements of Jupiter's atmosphere reveal conditions to be dry and windy; but is this true globally or just the result of local weather?

. . . And Io yields still more surprises. Almost four centuries after Galileo's telescope revealed moons orbiting Jupiter, those same moons are revealing their secrets to the Galileo spacecraft---starting with Io's differentiated structure and magnetic properties.
