  • efg's Fractals and Chaos -- Glynn Function Gallery Page
    which was news to me when I read about it in his excellent book See this image in the CycleColors example on the Palettes and Colors page This was part of the Computer Graphics World review of Cliff Pickover s book Mazes for the Mind Computers and the Unexpected St Martin s Press 1992 Color plate before page 173 This image is similar to Spiraling Tree Biomorphic Cells in The Pattern Book Clifford Pickover ed World Scientific 1995 p 239 The Spiraling Tree Biomorphic Cells images were selected for the second place three way tie prize in The Pattern Book The Cell Division image was also awarded a special prize at the Complex Systems 92 Australian National University Conference for its extremely life like character See the SigGraph experimental online document or the conference proceedings in Complex Systems From Biology to Computation IOS Press Amsterdam 1993 Clifford Pickover included his black and white version of this fractal biomorph in his book Computers and the Imagination St Martin s Press 1991 frontispiece for Part I I was amused by Cliff s acknowledgement in Appendix F when he suggested further information could be obtained from me at the Glynn Function Study Center

  • efg's Fractals And Chaos -- Fractal Discovery Lab
    Discovery Lab was part of Digital Visions The Art of Computer Science at the Kansas City Museum July September 1992 and later was displayed at Wonderscope The Fractal Discovery Laboratory is a computer program designed for use in a science museum or school setting The Lab introduces the concepts of fractals and mathematical chaos in a way that is entertaining to a four year old yet may be interesting to a mathematician With a mouse just point and click to make all selections The Discovery Lab is available in English or French The Art Gallery shows the beauty of fractals and amazing mathematical worlds of chaos The Gallery has 72 pre computed fractal images Special Effects add a dynamic dimension to each image The Gallery s Slide Show starts automatically as a screen saver whenever the Lab is inactive for more than 30 seconds The Microscope shows several enlargements of five particular fractal images Starting with a macroscopic view the Microscope enlarges some images to beyond a magnification of 5 000 000X The Microscope consists of 85 pre computed fractal images Six different Movies show fractals in motion Each movie consists of a series of frames that are shown as

  • The Guidon
    of those big bursts of fire in the sky Keys to the exercise are range angle and a simple mathematical calculation So build the astrolabe and start your budding Edwin Hubble off on the exploration of science How to Count the number of seconds elapsed from the instant you see the light of a firework until you hear the sound One thousand one one thousand two and so on Estimate the angle in degrees as shown in drawing Making a simple astrolabe Since estimating angles is difficult make a simple astrolabe to measure the angles You will need the following 1 six inch plastic protractor with hole 2 plastic drinking straw 3 piece of string or heavy thread about two feet long 4 large paper clip or binder clip for a weight 5 some tape To make the astrolabe follow these simple steps 1 Tape the drinking straw to the straight edge part of the protractor 2 Make a loop with the string that passes through the hole in the protractor 3 Attach the two ends of the string together and to the paper clip weight Take measurements with the astrolabe of both the top and bottom of the firework
