Solar active regions consist of strongly magnetic sunspots and surrounding regions of more diffuse magnetic field.

These regions are the origin of solar activity which controls space weather and causes beautiful phenomena such as aurora but in some cases also damage to satellites or power grids. Solar active regions are thought to be the result of magnetic flux concentrations - bundles of magnetic field lines - rising from deep in the solar interior and penetrating the surface. A team consisting of researchers from the Max Planck Institute for Solar System Research (MPS), The University of Göttingen, NorthWest Research Associates, and the High Altitude Observatory of the National Center for Atmospheric Research has now shown tha...

After the Science Wars What is a Thought Experiment, Anyhow? Chaos & An Unpredictable Tomorrow Peter Saltzstein  finds that Chaos Theory yields unexpected philosophical results. The future is not what it used to be. I mean, an intriguing implication of the branch of mathematics called  chaos theory  is that the future states of complex dynamical systems such as the weather, the human brain, the stock market, evolution, and history itself, are not what we once thought them to be. Specifically, ...
