Fibonacci Numbers and Phyllotaxis
In the late 1970s Adler turned his attention to the question of phyllotaxis, specifically to the arrangement of plant spirals according to the Fibonacci sequence. His papers in the Journal of Theoretical Biology serve as the basis for a revival of interest in the subject. In 2012, a compilation of these papers were published in a book by World Scientific Publishing. The book's foreword is by Adler's son, Stephen L. Adler, and the diagrams by his daughter, Peggy Adler. Adler gave lectures about phyllotaxis at many universities and conferences in the United States and internationally, including the University of Kansas, The Institute for Advanced Study and West Point.

Famous quotes containing the word numbers:
“The barriers of conventionality have been raised so high, and so strangely cemented by long existence, that the only hope of overthrowing them exists in the union of numbers linked together by common opinion and effort ... the united watchword of thousands would strike at the foundation of the false system and annihilate it.”
