→分形与“粗糙度理论”
曼德布洛特创造了第一个“[[粗糙度理论]]”，他看到了山脉，[[海岸线]]和[[河流盆地形状]]的“粗糙度”。植物，血管和肺的结构的“粗糙度”；还有[[星系聚集]]的“粗糙度”。他个人的追求是创建一些数学公式来测量此类物体在自然界中的整体“粗糙度”<ref name=Mandelbrot />。他首先问自己各种与自然有关的问题：

曼德布洛特在1967年《科学》杂志上发表的论文《英国的海岸线有多长？统计自相似性和分形维数How Long Is the Coast of Britain? Statistical Self-Similarity and Fractional Dimension》中讨论了'''<font color="#ff8000"> [[豪斯多夫维数]]Hausdorff dimension</font>'''的自相似曲线。这些都是分形的例子，尽管当时曼德布洛特在论文中并没有使用这个术语，因为他直到1975年才创造这个名词。该论文是曼德布洛特关于分形主题的第一批出版物之一。<ref>"Dr. Mandelbrot traced his work on fractals to a question he first encountered as a young researcher: how long is the coast of Britain?": Benoit Mandelbrot (1967).
