1981 (Volume 12, No. 2)Planetology -- Earth Sciences Special: The Terrestrial PlanetsThe solar system's inner, terrestrial planets are not all at the same evolutionary stage. Studies of each casts light on where the others have been-or are going. A solar system model.Mort LaBrecquePDF
1981 (Volume 12, No. 5)Hydraulic Piston Corer: Coring Near the MudlineThe hydraulic piston corer--a homely invention--makes possible retrieval of soft sediment cores that rotary bits reduce to mush.Mort LaBrecquePDF
1982 (Volume 13, No. 1)Vlsi Technology: Faster Switches, Smaller Wires, Larger ChipsVery large scale integrated (VLSI) circuit technology is revolutionizing the design of computer microcircuits. Some of the mystery is coming out of the process.Mort LaBrecquePDF
1982 (Volume 13, No. 4)Integrated Optics: Integrated Optics: A Communications RevolutionIntegrated optical devices will do much that integrated electronic circuits now do. The problem of the optical switching transistor may set the limit. Optical switching transistors.Mort LaBrecquePDF
1983 (Volume 14, No. 3)Proteins' Tertiary Structure: Protein FoldingLearning how proteins acquire the multifarious shapes they need in order to function is as complex as the molecules are convoluted.Mort LaBrecquePDF
1984 (Volume 15, No. 1)Architectures -- Computer Research Special: The Many Ways Data Must FlowTo break the bottleneck inherent to today's linear computer architectures, parallel schemes of many kinds are being devised. Parallel number-crunchers.Mort LaBrecquePDF
1984 (Volume 15, No. 4)Organic Synthesis -- Engineering Research Special: Synthesizing Organics ElectricallyElectro organic synthesis promises to be economical for classes of chemicals that are not easy to define. Organizing the record.Mort LaBrecquePDF
1985 (Volume 16, No. 1)Fractals -- Symmetry Special: Fractal SymmetryMandelbrot's arcane mathematics contains its own arcane symmetries. Nonlinear fractals.Mort LaBrecquePDF
1985 (Volume 16, No. 4)Chemistry -- Scientific Computing Special: Many Chemists, Many Cups of TeaA chemist's approach to advanced scientific computing is as unique as the kind of chemistry being done; neither theoreticians nor experimenters necessarily share hardware or software needs. One chemist's experience. Chemical plant design. Modeling failure. Expert Chemical Systems. Mort LaBrecquePDF
1985 (Volume 16, No. 4)Chemistry -- Scientific Computing Special: Expert Chemical SystemsAdvances in computational chemistry are not limited to the familiar aspects of numerical processing. Symbolic processing especially as used in programming for artificial intelligence, is a real, albeit, subtle presence. Mort LaBrecquePDF
1986 (Volume 17, No. 1)Manybody -- Scientific Computing Special III: Many-body ProblemsOnce the number of bodies interacting with each other grows beyond two, the problems of computing their effects on each other begins to grow out of control.Mort LaBrecquePDF
1986 (Volume 17, No. 4)Fractal Applications: Fractal Applications IFractals are far more than the fantastic fruits of the crossmatching of geometric theory and computer graphics. Both the spawn and the seed of a mathematical revolution, they are influencing an increasing range of scientific undertakings. The Mandelbrot set. Mort LaBrecquePDF
1987 (Volume 18, No. 2)Fractal Applications: Fractals in PhysicsThough the theory is reasonably clear, researchers are still largely in the dark about the physical bases of fractals, which are, paradoxically, increasingly important in physics.Mort LaBrecquePDF
1987 (Volume 18, No. 4)Quasicrystals: Opening the Door to Forbidden SymmetriesFivefold quasiperiodic symmetries have rapidly made their way from prohibited crystallographic anomalies to subjects of many-pronged investigation in condensed matter physics; their fundamental characteristics are still not well understood. I: Discovery. II: Follow-up. III: Competing models. IV: Decoration and utilization. Pauling's twinning model. The Penrose tilings. Mort LaBrecquePDF
1988 (Volume 19, No. 3&4)Biogeochemical Cycles -- Global Change Special: A Global Chemical FluxThe constant, cycling flow of such critical elements as carbon, nitrogen, and sulfur among the earth's atmospheric, oceanic, geological, and biological regimes becomes a major challenge to those scientists seeking a handle on the processes of global change. The view from space. Mort LaBrecquePDF
1989 (Volume 20, No. 1)Molecular Electronics (i:organic Molecules): Circuits and Devices a Molecule WidePart I of a special report. With the hype removed, efforts to design electronic devices made of single molecules are settling in for the long, productive haul. Biochips are in the barrel too.Mort LaBrecquePDF
1989 (Volume 20, No. 1)Molecular Electronics (II: Biological Molecules): Devices That Assemble ThemselvesPart II of a special report. Electronic devices that can assemble themselves without any outside assistance are luring some researchers to the promise of proteins. Langmuir-Blodgett films.Mort LaBrecquePDF
1989 (Volume 20, No. 3)Organelle Transport -- Cell Biology Special: The Engines Within CellsVesicles and other subcellular organelles course constantly along the cytosceletal microtubules that crisscross a cell's interior. The engines that drive them, like the fuel that powers them, are turning out to be the same throughout the animal kingdom.Mort LaBrecquePDF
1989 (Volume 20, No. 4)Global Change: GLOBAL CHANGE: A two-part special reportOn every front, signals that could reveal a vector of change in global climate remain inextricably buried in background. Efforts intensify to tease out reliable data so that directions and rates of change can be clearly perceived. DETECTING CLIMATE CHANGE I: Taking the world's shifting temperature. DETECTING CLIMATE CHANGE II: The impact of the water budget.Mort LaBrecquePDF
1990 (Volume 21, No. 2)Global Change: Clouds and Climate: A Critical Unknown In Global Change EquationsOf all the pieces in the global-change puzzle, the role of clouds may be the most elusive. Until it can be defined and incorporated into climate models, the models will remain imprecise indicators of things to come. Aerosols and cloud feedback.Mort LaBrecquePDF
1991 (Volume 22, No. 1)Cluster Chemistry: A Fifth State of MatterBound by the weakest of chemical bonds and occupying a state of matter somewhere between the gaseous and the liquid or solid, chemical clusters have become subject to study only as techniques emerged in the past few decades. Tools of the trade. Magic clusters. A clathrate ion cluster. Mort LaBrecquePDF
1992 (Volume 23, No. 1)Infrared Astronomy: IR Arrays in Space and on the GroundMultiple, interconnected receptors take their place in yet another of astronomy's windows to the cosmos. These arrays are measured in microns, not the meters of optical or the kilometers of radio interferometry. What the arrays are disclosingMort LaBrecquePDF
1992 (Volume 23, No. 2)Fractals In Chemistry: To Model the Otherwise UnmodelablePhysical chemists are joining their colleagues in condensed-matter (and other) physics in their far-ranging application of the wonder that Mandelbrot wrought. Fundamentally fractal.Mort LaBrecquePDF
