About previous books: Read 2-3 lines, and you are happy for the rest of the day!Theoretically, angular velocity and area measures are exploited. The applications are; boundary layer replications for a bar chain, fractals to describe buckling, gait, super-fluidicity, tornado & plasma dynamics due to densification, and EM in Photovoltaic.Angular velocities, sometimes called rotations, are present in many motions and processes: Helium 4, in its superfluid state, is scrutinised while climbing up a wall. Photovoltaic, i.e. engineering for Schottky diods and solar panels, is analysed. Accelerated spin in Figure skating is compared with a branch in the RMB-bifurcation. Singular solutions are derived for area flows. These apply to elongated shapes and rotations into densifications and appear as extreme weather, e.g. tornados with distinct boundaries. In situ observation of such structures gives that they operate by themselves, with different shapes and somehow resemble creatures.
