stationary cylinder filled with water? According to new work by physicists
in Denmark, you produce rotating polygons with up to six corners on the
water's surface. This new and spectacular type of "instability" could be
used to study a wide variety of complex systems in physics, including
rotating flows on Earth, hydraulic machinery in industry, vortices and
tornadoes (Phys. Rev. Lett. 96 174502) ...
