Year (Volume & No.)TitleAbstractAuthorDownload
1985 (Volume 16, No. 1)Supersymmetry -- Symmetry Special: Laboratory SupersymmetrySupersymmetry has been shown to hold in the realm of the nucleon of atoms. What good is a baby?T.A. HeppenheimerPDF
1985 (Volume 16, No. 2)Earthquake Prediction: Earthquakes to ComeAnticipating an earthquake and predicting one are not quite the same thing. What does it take to put together a dependable earthquake prediction?T.A. HeppenheimerPDF
1985 (Volume 16, No. 4)Mathematics Computation -- Scientific Computing Special: Mathematicians at the Receiving EndAdvanced scientific computing is helping to turn some mathematics into an experimental science.T.A. HeppenheimerPDF
1986 (Volume 17, No. 2)Chaos: Routes to ChaosStudies of the transitions from predictable to unpredictable states weave together the concerns of a growing cadre of scientists and engineers.T.A. HeppenheimerPDF
1986 (Volume 17, No. 3)Quantum: Experimental Quantum MechanicsEfforts to test experimentally the assertions of quantum mechanics must match conceivable equipment to ideas that remain inconceivable in a naive, non-quantum world.T.A. HeppenheimerPDF
1987 (Volume 18, No. 1)Engineering -- Education Special: Engineering Education:Stability under strain. Thanks largely to industrial demand, swelling student populations are encountering shrinking faculties. Despite that and some other problems, the main shape of engineering education seems to be largely what the doctor is ordering.T.A. HeppenheimerPDF
1988 (Volume 19, No. 2)Topology: The Mathematics of ManifoldsIn the arcane world of multi-dimensional surfaces, mathematicians are forging new bonds with physics and posing new riddles for that sister discipline. Degrees of topological equivalence. Topology and fractals. DNA topology. Cartography and topology.T.A. HeppenheimerPDF
1988 (Volume 19, No. 3&4)Deep Earth -- Global Change Special: The Sum of Its PartsAn array of new techniques and the insights that stem from their application are providing an emerging picture of the earth's interior unprecedented in detail and complexity. Processes as well as phenomena come into focus. Inner core and core-mantle boundary.T.A. HeppenheimerPDF
1988 (Volume 19, No. 3&4)Instrumentation -- Global Change Special: Forging the ToolsNowhere more than in the design and dispersal of the instruments needed to monitor and study global change is the application of ingenuity to the pursuit of scientific research more apparent. Challenges abound.T.A. HeppenheimerPDF
1989 (Volume 20, No. 2)Quantum Chaos: Classical Mechanics, Quantum Mechanics, and the Arrow of TimeA resolution of the paradox presented by the appearance of chaos in classical but not in quantum systems suggests that, given enough time for its kinks to work themselves out, chaos may be more apparent than real. Experiments are shrinking the distance between the quantum and classical worlds.T.A. HeppenheimerPDF
1990 (Volume 21, No. 1)Goedel: The Long Shadow of Kurt GoedelEarly in his career, Kurt Goedel shook the foundations of mathematics. His work has since become part of the bedrock of mathematical research.T.A. HeppenheimerPDF
1990 (Volume 21, No. 3)Quantum Cosmology: Bridging the Very Large and Very SmallIn their efforts to unravel the universe's mystery, physicists are drawing on quantum mechanics and are finding as many imponderables as there are avenues of promise and hope. Quantum gravity.T.A. HeppenheimerPDF
1991 (Volume 22, No. 1)Turbulence Modeling: Some Tractable Mathematicsfor Some Intractable Physics. Mathematical modelers' efforts to come to terms with turbulent phenomena have made contributions to the solution of engineering problems; physicists concerns are less readily addressed. Ptolemy's solar system is an apt parallel. Turbulence measurements T.A. HeppenheimerPDF
1991 (Volume 22, No. 4)Symbol Manipulation: Computer Algebra: Speed Is Not AllNew methods of computerized symbol manipulation are producing `new and deep mathematical insights that lead to new algorithms of great power.` The reach of mathematics is extended. Limits to excellence. From seed to fruit.T.A. HeppenheimerPDF
1992 (Volume 23, No. 1)Quantum Gravity: The Grandest UnificationInterleaving the principles of general relativity with those of quantum mechanics requires the invention of new physics. What might work for matter and energy dissolves when space must be incorporated. And it must be. Cosmology at 10-33 cm. Seeing the elephant.T.A. HeppenheimerPDF
1992 (Volume 23, No. 3)High-temperature Superconductivity: Woodstock Plus Five and CountingThe extravagant futures forecast for HTC are being replaced by more reasonable expectations, while experimentalists and theorists both settle in for what is likely to be a fruitful long haul.T.A. HeppenheimerPDF
