The Barnsley Fern is a fractal named after the British mathematician Michael Barnsley who first described it in his book ''Fractals Everywhere''.〔(Fractals Everywhere ), Boston, MA: Academic Press, 1993, ISBN 0-12-079062-9〕 He made it to resemble the Black Spleenwort, ''Asplenium adiantum-nigrum''. == History == The fern is one of the basic examples of self-similar sets, i.e. it is a mathematically generated pattern that can be reproducible at any magnification or reduction. Like the Sierpinski triangle, the Barnsley fern shows how graphically beautiful structures can be built from repetitive uses of mathematical formulas with computers. Barnsley's book about fractals is based on the course which he taught for undergraduate and graduate students in the School of Mathematics, Georgia Institute of Technology, called ''Fractal Geometry''. After publishing the book, a second course was developed, called ''Fractal Measure Theory''.〔 Barnsley's work has been a source of inspiration to graphic artists attempting to imitate nature with mathematical models. The fern code developed by Barnsley is an example of an iterated function system (IFS) to create a fractal. He has used fractals to model a diverse range of phenomena in science and technology, but most specifically plant structures. —Michael Barnsley ''et al.''〔Michael Barnsley, ''et al.'',〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Barnsley fern」の詳細全文を読む スポンサード リンク
