FOTD -- October 06, 2010 (Rating 7) Fractal visionaries and enthusiasts: For some reason, the TV channels these days are filled with programs about looming catastrophes and the end of civilization. So why not have one of the looming catastrophes appear in fractal form? This is just what happened in today's FOTD, which captures the hypothetical asteroid-impact catastrophe at the moment of impact. Actually, the scene shows an order 1.15 minibrot in the parent fractal that appears when the formula Z^(1.15)+C is iterated at the MandelbrotBC3 formula's ground level. This parent is shaped much like the minibrot in today's image, and is decorated on its southwest side by a field of rather fantastic zigzagging fila- ments. Today's image lies about halfway out in this field. The name "Asteroid Impact" says it all. The rating of a 7 might be a little overdone. The colors appear a bit too brilliant to me. The calculation time of 1-3/4 minutes is a lot shorter than the time it took for the asteroid to reach the earth. And even if the asteroid never arrives, the finished image is or soon will be available for instant viewing on the FOTD web site at: <http://www.Nahee.com/FOTD/> Chilly temperatures and occasional light rain kept activity suppressed here at Fractal Central on Tuesday. The fractal cats leaped to their shelf for joy when the sun briefly appeared in the afternoon, taking the chill from the temperature of 54F 12C. Unfortunately, the sun went behind the clouds after bringing only 5 minutes warmth, and the cats were sorely disappointed. My day was slow and routine. FL killed time watching those hot Latin soap operas. The next FOTD will be posted in 24 hours. Until then, take care, and when will we capture a live bigfoot?
