    Direct coronal heating from dissipation of magnetic field

    Get PDF
    The visible corona of the Sun appears to be heated by direct dissipation of magnetic fields. The magnetic fields in the visible corona are tied at both ends to the photosphere where the active convection continually rotates and shuffles the footpoints in a random pattern. The twisting and wrapping of flux tubes about each other produce magnetic neutral sheets in a state of dynamical nonequilibrium such that the current sheets become increasingly concentrated with the passage of time. Dissipation of the high current densities takes place regardless of the high electrical conductivity of the fluid. The convection on the feet of the lines of force at the surface of the Sun goes directly (within a matter of 10 to 20 hours) into heat in the corona. The rate of doing work seems adequate to supply the necessary 10 to the 7th power ergs/square cm. sec for the active corona

    In this paper, we consider some issues surrounding the teaching of mathematics to pre-service teachers. In particular. we look at the possibilities for teaching elementary mathematics from an advanced standpoint and alignments of curriculum that have the capacity to enhance student involvement in the making of the mathematics.The particulars of the James Madison University curriculum are used to illustrate many of the points
