Benoit B.[n 1] Mandelbrot[n 2] (20 November 1924 – 14 October 2010) was a Polish-born French-American mathematician and polymath with broad interests in the practical sciences, especially regarding what he labeled as "the art of roughness" of physical phenomena and "the uncontrolled element in life".[5][6][7] He referred to himself as a "fractalist"[8] and is recognized for his contribution to the field of fractal geometry, which included coining the word "fractal", as well as developing a theory of "roughness and self-similarity" in nature.

伯努瓦 曼德布洛特（1924年11月20日至2010年10月14日）是波兰裔法国裔美国数学家和博学家，对实用科学有着广泛的兴趣。他将其称为物理现象的“粗糙艺术”和“生活中不受控制的元素”。他称自己为“分形主义者”，并因其对分形几何学领域的贡献而受到认可，其中包括创造了“分形Fractal”一词，并发展了自然界中的“'''<font color="#ff8000"> 粗糙度Roughness</font>'''和'''<font color="#ff8000"> 自相似性Self-similarity </font>'''”理论。

In 1936, while he was a child, Mandelbrot's family emigrated to France from Warsaw, Poland. After World War II ended, Mandelbrot studied mathematics, graduating from universities in Paris and the United States and receiving a master's degree in aeronautics from the California Institute of Technology. He spent most of his career in both the United States and France, having dual French and American citizenship. In 1958, he began a 35-year career at IBM, where he became an IBM Fellow, and periodically took leaves of absence to teach at Harvard University. At Harvard, following the publication of his study of U.S. commodity markets in relation to cotton futures, he taught economics and applied sciences.

1936年，当曼德布罗特还是个孩子时，一家人从波兰华沙移民到了法国。第二次世界大战结束后，曼德布洛特学习了数学，从巴黎和美国的大学毕业，并获得了加州理工学院的航空硕士学位。他的职业生涯大部分时间都是在美国和法国度过，拥有法国和美国双重国籍。1958年，他在IBM开始了35年的职业生涯，并在那里成为了IBM院士，定期请假到哈佛大学任教。在哈佛大学发表关于棉花期货的美国商品市场研究之后，他开始教授经济学和应用科学。
Because of his access to IBM's computers, Mandelbrot was one of the first to use computer graphics to create and display fractal geometric images, leading to his discovery of the Mandelbrot set in 1980. He showed how visual complexity can be created from simple rules. He said that things typically considered to be "rough", a "mess", or "chaotic", such as clouds or shorelines, actually had a "degree of order".[10] His math and geometry-centered research career included contributions to such fields as statistical physics, meteorology, hydrology, geomorphology, anatomy, taxonomy, neurology, linguistics, information technology, computer graphics, economics, geology, medicine, physical cosmology, engineering, chaos theory, econophysics, metallurgy, and the social sciences.

由于曼德布罗特可以使用IBM的计算机，因此他是最早使用计算机图形来创建和显示分形几何图像的人之一，因此他于1980年发现了曼德布洛特集合。他展示了如何从简单的规则图形创建出视觉复杂的图形。他认为那些通常被认为是“粗糙”，“杂乱”或“混乱”的事物，例如云层或海岸线，实际上都具有“'''<font color="#ff8000"> 有序度Degree of order </font>'''”。他以数学和几何学为中心的延申研究领域包括了统计物理学，气象学，水文学，地貌学，解剖学，分类学，神经学，语言学，信息技术，计算机图形学，经济学，地质学，医学，物理宇宙学，工程学，混沌理论等领域的贡献 ，经济物理学，冶金学和社会科学。
As a visiting professor at Harvard University, Mandelbrot began to study fractals called Julia sets that were invariant under certain transformations of the complex plane. Building on previous work by Gaston Julia and Pierre Fatou, Mandelbrot used a computer to plot images of the Julia sets. While investigating the topology of these Julia sets, he studied the Mandelbrot set which was introduced by him in 1979. In 1982, Mandelbrot expanded and updated his ideas in The Fractal Geometry of Nature.[21] This influential work brought fractals into the mainstream of professional and popular mathematics, as well as silencing critics, who had dismissed fractals as "program artifacts".

作为哈佛大学的客座教授，曼德布洛特开始研究名为'''<font color="#ff8000"> 朱莉娅集合Julia sets</font>'''的分形，这些分形在复杂平面的变换下依旧保持不变。在加斯顿·朱莉娅Gaston Julia和皮埃尔·法图Pierre Fatou先前工作的基础上，曼德尔布洛特使用计算机绘制出了朱莉娅集合的图像。在他研究这些朱莉娅集的拓扑时，他研究了他于1979年提出的曼德布洛特集。1982年，他在《大自然的分形几何学》一书中扩展并更新了他的思想。这项颇具影响力的著作将分形技术引入到专业数学和大众数学中，同时也进入到了那些将分形技术仅视为“程序工件”的批评者眼中。

In 1975, Mandelbrot coined the term fractal to describe these structures and first published his ideas, and later translated, Fractals: Form, Chance and Dimension.[22] According to computer scientist and physicist Stephen Wolfram, the book was a "breakthrough" for Mandelbrot, who until then would typically "apply fairly straightforward mathematics ... to areas that had barely seen the light of serious mathematics before".[10] Wolfram adds that as a result of this new research, he was no longer a "wandering scientist", and later called him "the father of fractals":

1975年，曼德布洛特创造了“分形”一词来描述这些结构，并首先发表了他的想法，其翻译为《分形：形式，机会和维度》。根据计算机科学家和物理学家斯蒂芬·沃尔夫拉姆Stephen Wolfram的说法，这本书对曼德尔布洛特来说是一个“突破”，他在那之前通常会“将相当简单的数学应用于……以前几乎没有看到过的严肃数学领域”。沃尔夫拉姆补充说，由于这项新研究，他不再是“流浪的科学家”，后来称他为“分形之父”：

One might have thought that such a simple and fundamental form of regularity would have been studied for hundreds, if not thousands, of years. But it was not. In fact, it rose to prominence only over the past 30 or so years—almost entirely through the efforts of one man, the mathematician Benoit Mandelbrot.

可能有人以为，这种简单而基本的规律已经被研究了数百年甚至数千年，但事实并非如此。实际上，它仅在过去30多年中才受到关注，而且几乎完全是通过一个人的努力，即数学家伯努瓦 曼德布洛特。
Exploring this set I certainly never had the feeling of invention. I never had the feeling that my imagination was rich enough to invent all those extraordinary things on discovering them. They were there, even though nobody had seen them before. It's marvelous, a very simple formula explains all these very complicated things. So the goal of science is starting with a mess, and explaining it with a simple formula, a kind of dream of science

在探索这个集合的时候我并未感觉在发明一个新概念。我也从没有感觉到我的想象力足以发现所有这些非凡的事物。其实他们就一直呈现在那里，只是过去没有人注意过他们。一个如此简单的公式就可以解释所有这些异常复杂的事物，太难以置信了。因此，科学的目标是从一团乱开始，再由一个简单的公式来解释它。我想这是研究科学的梦想。
In his paper titled How Long Is the Coast of Britain? Statistical Self-Similarity and Fractional Dimension published in Science in 1967 Mandelbrot discusses self-similar curves that have Hausdorff dimension that are examples of fractals, although Mandelbrot does not use this term in the paper, as he did not coin it until 1975. The paper is one of Mandelbrot's first publications on the topic of fractals.

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》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。
