斐波纳契数列在现代物理、准晶体结构、化学等领域都有直接的应用，为此，美国数学会从1960年代起出版了《斐波纳契数列》季刊，专门刊载这方面的研究成果。 (Fibonacci series in modern physics, quasi-crystalline structure, chemical and other fields have direct application, for which the American Mathematical Society published since the 1960s, " Fibonacci series" quarterly, is devoted to research in this area .)
