; June 26, 1997: The Vanished Butterflies ; ; buitterflies ; ; Fractal visionaries: ; ; Today's fractal looks like an object of some sort, but I just can't ; place what it is that the picture reminds me of. One thing that ; immediately comes to mind is that wonderful series of "Circle Limit" ; drawings by M.C. Escher, where the objects increase to infinity as the ; limit of the circle is approached, almost as though they were imbedded ; in a space of constant negative curvature. But if this is the case, ; today's fractal should have been called "Octagon Limit". ; ; This fractal is a good example of the type of image I prefer -- one that ; subtly hints at something familiar without actually picturing it. It is ; this hint of familiarity that turns people on to fractals, just as it ; does to art of all kinds. ; ; There is no reason for people to be put off by the mathematical aspect ; of fractals. One can appreciate a rainbow without an understanding of ; the laws of reflection and refraction. One can also appreciate a ; fractal without understanding the complex math behind it. In fact, I no ; longer bring up the topic of math unless I see that the person is ; actually interested in it. ; ; The world around us is filled with fractal shapes. It always has been ; filled with fractal shapes -- we simply did not recognize them before we ; discovered fractals. When I see the mountains and clouds, I see ; fractals; when I see a leaf, I see a fractal network; when I see the ; Arctic ice cap photographed from a plane, I see a fractal pattern. When ; I see a fractal on the screen, I see these physical things and much ; more. ; ; Certainly some of those fractal patterns that remind us of nothing ; actually do have undiscovered physical counterparts, perhaps on other ; planets, perhaps yet undiscovered on our own. And I never stop ; wondering the ultimate thought -- is the universe the greatest fractal ; of all? ; ; Today's fractal may not be the greatest fractal of all, but it's an ; acceptable one. After all, it's difficult to come up with the greatest ; fractal of all every day. The image is that of an obscure slice of the ; (-Z)^1.1 mandeloid. The finished image has been posted as always to ; a.b.p.f. and a.f.p. ; ; For tomorrow -- who knows. We'll just have to wait and see. ; ; Jim Muth ; jamth@mindspring.com ; ; START PAR FILE FOR 19.6==================================== TheVanishedButterf { ; time=0:00:19.56-SF5 on P4-2000 reset=1960 type=formula formulafile=basicer.frm formulaname=ManMinusN-XZ passes=1 center-mag=+1.58\ 3346097323374/+4.075536133500432/728.7263/0.2393/\ -60.0434214984606456/35.3825248139930579 inside=0 params=0.75/0/1.1/0/1/0 float=y maxiter=500 logmap=yes periodicity=10 colors=000`hPafQbeRdcReaSf_TgZUhXUjVVkTWlSXmQXnOYo\ MZqL_rJ_sH`rH`pH`oHamHalHajHaiHagHafHbeGbcGbbGb`Gb\ _GbYGcXGcVGcUGcWIaZKZ`MXbNUePSgRPaVTWYXQa`00MDii00\ N1pq04P2M_27R48R7AR9BSBDSDESGFSIHTKITMKTPLTRMTTOUV\ PUYQU_SUaTUcVVfWVhXVjZVl_WoaWqbWqcWpdWpeXpfXogXogX\ ohXniXnjYnkYnlYmmYmnYQWGPVGPUGOTFOSFORFNQENPEMOEMM\ ELLDLKDLJDKIDKHCJGCJFCIEBIDBICBHBBHAAG9AG8AE3CF4BF\ 5BG6AG7AH89H99IA8IB8JC7JD7KE6KF6LG5LH5MI4MJ4NK3NL3\ OM2ON2PO1OQ0PP1PP1PP1PP1PP1PP2QP2QP2QP2QP2QP2QP3QP\ 3RO3RO3RO3RO3RO4RO4SO4SO4SO4SO4SO5SO5SO5TN5TN5TN5T\ N6TN6TN6TN6UN6UN6UN7UN7UN7UN7VM7VM7VM8VM8VM8VM8VM8\ WM8WM9WM9WM9WM9WM9VK8WL9WL9WL9WM9WM9WMAWNAWNAWNAWO\ AWOBWOBWPBWPBWPBWQCWQCWQCWRCWRCWRDXSDXSDXSDXTDXTEX\ TEXUEXUEXUEXVFXVFXVFXWFXWFXWFXWGXXGXXGXXGXYGXYHXYH\ YZHYZHYZHY_IY_IY_IY`IY`IY`JYaJYaJYaJYbJVhJUgJUfJUe\ JTdITbISaIS`IR_HRZHRYHQXG } frm:ManMinusN-XZ { z=real(pixel)+flip(real(p1)), c=imag(pixel)+flip(imag(p1)): z=(-z)^p2+(p3*c), |z| <= 16 } ; END PAR FILE FOR 19.6====================================== ;
