The arms of spiral galaxies are roughly logarithmic, as are the bands of tropical cyclones and many biological structures such as shells. These are spirals which make a constant angle with the line connecting any point to the centre. Rays of light emanating from the centre reflect off the spiral and burn the image of a second identical spiral, slightly rotated.Sunday, April 13, 2014
