ARTICLES - The Discovery of Rapid Climate Change .- Only within the past decade have researchers warmed to the possibility of abrupt shifts in Earth's climate. Sometimes, it takes a while to see what one is not prepared to look for. Spencer Weart- pp. 30-36 .- A Topological Look at the Quantum Hall Effect .- The amazingly precise quantization of Hall conductance in a two-dimensional electron gas can be understood in terms of a topological invariant known as the Chern number. Joseph E. Avron, Daniel Osadchy, and Ruedi Seiler pp. 38-42.- Quantum Physics Under Control .- Thanks to the increasing ability to coherently control quantum systems, designer Hamiltonians can be created to explore new physics and to yield a better understanding of complex phenomena. Ian Walmsley and Herschel Rabitz pp. 43-49.- PHYSICS UPDATE- Physics Update.- Phil Schewe and Ben Stein p. 9 .- LETTERS - Science for All Americans: Seeking a Common Knowledge Core Across Disciplines.- Richard Conn Henry, Jo Ellen Roseman, Rustum Roy, and Leon Lederman pp. 10-12 .- Ronald Richter, Genius or Nut?.- Friedwardt Winterberg and Juan G. Roederer pp. 12-13 .- Baade, Shapley, and the Doubling of the Universe- Sidney van den Bergh and Norriss S. Hetherington pp. 13-14 .- Karl Brown's Role in TRANSPORT- David C. Carey p. 14 .- Group Velocity Is Not Signal Velocity - Max J. Lazarus- p. 14.- Correction - p. 14.- SEARCH AND DISCOVERY - Intriguing Properties Put Sodium Cobalt Oxide in the Spotlight - The compound is a good thermoelectric material. In hydrated form, it superconducts. And its structure is a theorist's dream. Barbara Goss Levi pp. 15-17 .- Band on the Run: Light Meets Shock Fronts in Virtual Photonic Crystals .- When light interacts with dynamically changing photonic structures, the results can be surprising -- and in some cases unprecedented. Steven K. Blau- pp. 17-19 .- Watching a Molecule Break Up Reveals How- Quickly It Changes Shape - It takes less than 60 femtoseconds for a doubly charged acetylene ion to change into its structural isomer vinylidene. Charles Day- pp. 19-21.- ISSUES AND EVENTS - Astronomy Foes Join Forces to Build Giant Telescope .- A new publicûprivate partnership faces hurdles but promises to make the US a formidable international competitor in ground-based astronomy. Toni Feder.- pp. 22-24 .- South Dakota Governor Pushes for Underground Lab as Homestake Water Rises.- NSF officials say approval of a science laboratory in the Homestake mine can come only after a multistep review process that takes "many months to many years." But a determined Republican governor and South Dakota's congressional delegation may bring politics to the science. Jim Dawson. pp. 24-25.- Italy's Underground Lab Recuperates From Toxic Spill, Gets New Director - Toni Feder.- pp. 25-26 .- Research Workforce Will Weaken Without Focus on Homegrown Talent .- Jim Dawson- pp. 26-27.- North American Women Sweep Top Honors at Intel Competition- Anthony Tweed p. 28.- News Notes .- Jim Dawson and Toni Feder- pp. 28-29
