Spider webs show a similar pattern. The low-pressure area over Iceland and the Whirlpool Galaxy resemble logarithmic spirals.Many materials develop spiral cracks either due to imposed torsion (twist), as in the spiral fracture of the tibia, or due to geometric constraints, as in the fracture ...

The use of a logarithmic curve pattern for blade design and an aerodynamic profile allows the present invention to not only be versatile in its uses, but also much more efficient at gathering forms of energy for different purposes.doi:US20120076656 A1Omar Nabil ABASS...
Spiral cracks may, however, arise in situations where no obvious twisting is applied; the symmetry is broken spontaneously. It has been found that the rank size pattern of the cities of USA approximately follows logarithmic spiral. The usual procedure of curve-fitting fails miserably in fitting a...
the directional pattern differs little from that for central excitation, with ellipticity coefficient of a spiral open at the center varying from 0.7 to 0.9 over a 1:2 frequency range; the input impedance depends weakly on the presence of reflection at the center of the spiral, is of an osci...
Properties of Logarithmic Spiral Beaches with Particular Reference to Algoa BayA hundred and fifty years ago De la Beche (1833) and later De Beaumont (1845) recognized that an intrinsic relationship existed between the angle of wave approach and the pattern of shoreline curvature (Lewis, 1937). ...
The results such as reflection coefficient, impedance, gain, efficiency, radiation pattern, and axial ratio bandwidth of the first and second iterated modified Koch logarithmic spiral antenna are similar to the original logarithmic spiral operating in frequency range 2.00鈥 18.30 GHz....
