... A self-consistent model for a thin accretion disk with turbulent convection is presented. ... In the gas pressure region, two distinct solutions are obtained. ... R : radiation pressure region, strong convection. ... It is interesting to note that the trend of convection to stabilize the radiation pressure dominated region, is evident even in models in which the disk viscosity is described by an parameter and the convective flux by the mixing length approach (Milsom, Chen, & Taam 1994). ...

The trailers started running in theaters many months before the movie came out, and I knew right away that "The Core" was ripe for a BA review. I remember distinctly that one line in the trailer said that the reversal of the Earth's magnetic field wipes out all life every 700,000 years. ... So they really blew it in the movie; they could have used real science to collapse the magnetic field, instead of the silliness of stopping the core. ...
