In the rest of the world, it's just another ; day. Today is the 100th anniversary of the great Baltimore ; fire -- the world's least-known conflagration. On this day in ; 1904 someone threw a cigarette butt down a ventilation grate and ; started a fire that burned over 1500 buildings in the downtown ; area. Only one person was reported as killed -- a drunk who was ; pulled from the harbor -- but it has always been uncertain that ; the death was actually due to the fire. ; ; Refusing to admit defeat and without federal assistance, the ; city pulled itself from the disaster and rose to be the nation's ; largest seaport for most of the 20th century. Only toward the ; end of the century did the bottom fall out. It now appears our ; no-longer-fair city leads the nation in everything bad and is in ; last place in everything good. The reasons for the decline are ; as numerous as the people still living in the city, which is ; where I still live by less than 1/2 mile, though this will likely ; change within two years. ; ; The connection of the fire to today's fractal is straight- ; forward. The fire started as a simple lit cigarette; today's ; fractal started as a simple mathematical expression -- ; (Z^2)-0.25(Z^3)+C. Like so many other things of the world ; around us, and even of the worlds within us, a fire has a ; fractal nature. Like fractals, a spark can find itself in con- ; ditions that are stable, neutral or unstable. If a tiny flame ; finds itself in stable conditions such as a burning match on a ; concrete sidewalk, it will quickly be extinguished. If the con- ; ditions are neutral, such as the flame of the wick of a large ; candle, it will continue unchanged indefinitely. But if the con- ; ditions are unstable, such as a flame in a large pile of waste ; paper, the flame will quickly grow without limit, as did that ; cigarette spark back in February of 1904. ; ; The parent fractal of today's image resembles a Mandelbrot set ; rotated 180 degrees. Its East Valley, which is now on the west ; side, is split down the middle into two separate valleys, ; leaving two entirely new shorelines along the interior edges of ; the valleys. Today's scene is located along one of these shore- ; lines, rather deep in the valley. ; ; In this area, the 'outside' parts of the fractal do not have the ; smooth, unbroken nature that we find in the 'outside' parts of ; the M-set. They are more like a swiss cheese in which the holes ; have been organized to form a regular pattern that can itself ; become the most important feature. ; ; In today's image however, it is not the holes that are the most ; important feature, it is the coloring. The amber ring close ; around the central midget is so brilliant that I named the ; entire image for it. The name I chose is "Amber Mandeloid". ; ; The rating of a 7 that I gave the image is above average, but ; the overall value has been cut to a measly 13 by the render ; time of over 53 minutes. In a few days I will adjust the ; method of calculating the overall value, or perhaps drop it ; entirely. ; ; The wait of nearly an hour for the parameter file to finish ; running may be avoided by downloading the completed image from ; Paul's FOTD web site at: ; ; ; ; Heavy rain all day Friday here at Fractal Central led to ; localized flooding and unhappy cats. The high temperature of ; 36F 2C helped not at all. It took almost a whole can of tuna ; to restore the spirits of the dynamic duo. Luckily, today is ; starting better. ; ; That's it for now. Until next FOTD, take care, and fill in the ; blanks before you leave. ; ; ; Jim Muth ; jamth@mindspring.com ; jimmuth@aol.com ; ; ; START PARAMETER FILE================================ Amber_Mandeloid { ; time=0:53:24.50--SF5 on a P200 reset=2003 type=formula formulafile=allinone.frm formulaname=MandelbrotMix2 function=ident passes=1 center-mag=-0.00161624027746348/+0.000070489860749\ 22/1.182809e+009/1/-155/1.14853522872881975e-008 params=1/2/-0.25/3/0/0/0/0 float=y maxiter=10000 inside=0 outside=tdis periodicity=10 colors=000kqihypdzxczz`zyYzuWxpTqkRkhOdcMZZJTVIMRF\ GMDAIA4D90AA76CF3DM0FV0Ga0Ii0Jq0Jy0Mx0Ov0Pu0Rs6TqC\ VpGWpMYnRZmY`kcaihchndhs`cfYWWVPJRJ9OD0L90PzsJnxFe\ zA_z4Wy0Tx0Qx0Nw4Kw7HwCEtFFoJHhMIcRJZWQ`ZUZcYZfZWk\ `TncOsdLvfIxiJykJzmJznLzpLzqLzuMzvMzxMzyOzzOzzOzzO\ uzIczCOy6MsCLmIJhOIaTGYZGRdFMkDGpCCvA6zA1zFJzJazZf\ dnkJzn0vd4nW9fMDZDJR4OJ0Tz7zzCuzGmzLdvOYqTPmYGh`9c\ d1Zi0Vm0`i0dh0kf0pd0vc0za0z`0zZ0zW0xT0qP0kM0dJ0ZG0\ TD0LA0F70940310000000000000011344979DADJDGPILWLO`O\ TfRYmV`sYdx`hsYipWkmVmiRndPpaOqZLsWJuRIvOFxLDyICzD\ 9zA7z76z44zA3yG3qL3kR3cY3Wa1Ph1In1As14y10z10sJAhaV\ Yum`mkadkdYifPiiJikChn4hp0fs0fu0fp0Zm3TiDLfMFaW9Zf\ 1Wp0Ty0Ps0On0Mh0Jc0IZ0GT0FO0CI0AD09907304003001000\ 0010030040060460970F90LA0PC0WC0`94a7Cc6Jd4Rf3Zh1fi\ 0mk6nfApaFpYJqVOqPVsLZsIcuDhv9mv6sx1xx0zy0zy0zz0zz\ 0zn0pc0aT6PGDC6L00T03W0AY } frm:MandelbrotMix2 {; Jim Muth a=real(p1), b=imag(p1), d=real(p2), f=imag(p2), g=1/f, h=1/d, j=1/(f-b), z=(((-a*b*g*h)^j)+(p4)), k=real(p3)+1, l=imag(p3)+100, c=fn1(pixel): z=k*((a*(z^b))+(d*(z^f)))+c, |z| < l } ; END PARAMETER FILE================================== ;
