Math 215. Fractals and computer graphics. Spring 1998.



 

 


  Course description: This hands on course surveys fractal geometry with applications to chaos theory and related computer software. You will learn about the mathematics behind the fractal images shown below (among others), and how to use software that produces them. The course will meet in the social sciences computer lab in Harkness, and enrollment is limited to 25. For a soon to be published account of previous offerings of this course written for other educators, see Ravenel's paper, A software driven undergraduate fractal course.  Here is a photo of of the meeting on teaching courses about fractals at Yale in December, 1997. Click here for the catalog description of Math 215.

Prequisites: One semester of calculus (Math 141, 161, 171 or equivalent AP credit) is required, and computer literacy is highly desirable.

Time and place: Monday and Wednesday, 2:00-3:15, Harkness 114. This room has a computer at every desk. Click here for computer instructions relevant to this course.

Text: Encounters with Chaos by Denny Gulick (McGraw-Hill 1992). A copy will soon be on reserve in Carlson Library.

Material to be covered: Most of Chapters 1, 2 and 4 of Gulick.  The main topics are discrete dynamics, the Mandelbrot and Julia sets, and iterated fucntion systems.
 
 
 

 

 

Grading:
Your course grade will be based on eight group homework assignments. These are to be done by groups of up to three people.   Each should result in a printed paper with computer generated illustrations, some of which may be animated.  I am open to suggestions for alternative experiments for each of these topics.  Contact me a week or more before an assignment is due if you want to try something different.
Class attendance is mandatory and your final grade will be discounted by 1% for each unexcused absence after January 21. Homework assignments are due at classtime unless otherwise noted and late assignments will not be accepted.

 

 

Software:
We will make substantial use of Fractint, an omnibus program that can quickly produce any fractal image you can think of. It will be the work horse program for this course and you should familiarize yourself with it as soon as possible. It comes with extensive online help. On the web you can find copy of the help manual and extensive information about Fractint commands. It has a formula mode and an L-systems mode, both of which enable you to create new types of fractals. Fractint runs under DOS, Windows and Unix, but I know of no comparable software for the Macintosh.
We will also use FDESIGN, a mouse driven program for experimenting with IFS attractors.
