Views Through a Mathematical Microscope.The strange object that follows is composed of a reflecting sphere surrounded by a sine wave bent into a spherical shape. This specialized sine wave is given by the equation that follows: x = (b2  c2 cos2 at)1/2 cos t y = (b2  c2 cos2 at)1/2 sin t z = c cos at
