Benoit B.[n 1] Mandelbrot[n 2] (20 November 1924 – 14 October 2010) was a Polish-born French and 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".[3][4][5] He referred to himself as a "fractalist"[6] 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.[7]


{{quote|Our constant fear was that a sufficiently determined foe might report us to an authority and we would be sent to our deaths. This happened to a close friend from Paris, Zina Morhange, a physician in a nearby county seat. Simply to eliminate the competition, another physician denounced her ... We escaped this fate. Who knows why? In 1958 the couple moved to the United States where Mandelbrot joined the research staff at the IBM Thomas J. Watson Research Center in Yorktown Heights, New York.

{引用 | 我们一直担心的是,一个足够坚定的敌人可能会向某个权威举报我们,我们将会被送去送死。来自巴黎的密友吉娜 · 莫汉格就遇到了这种情况,她是附近一个县城的内科医生。仅仅是为了消除竞争,另一个医生谴责她... 我们逃过了这个命运。谁知道为什么呢?1958年,这对夫妇移居美国,在那里曼德尔布洛特加入了位于约克敦海茨的 IBM 汤玛士·J·华生研究中心的研究人员。

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.

In his early work, he found that the price changes in financial markets did not follow a Gaussian distribution, but rather Lévy stable distributions having infinite variance. He found, for example, that cotton prices followed a Lévy stable distribution with parameter α equal to 1.7 rather than 2 as in a Gaussian distribution. "Stable" distributions have the property that the sum of many instances of a random variable follows the same distribution but with a larger scale parameter.

在他的早期工作中,他发现金融市场的价格变化并不遵循正态分布,而是具有无限方差的 l é vy 稳定分布。例如,他发现,棉花价格遵循一个 l é vy 稳定分布,参数 α 等于1.7,而不是像正态分布一样遵循2。“稳定”分布具有这样的性质: 一个随机变量的多个实例的和服从相同的分布,但具有更大的尺度参数。


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", like clouds or shorelines, actually had a "degree of order".[8] 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.[9]


Toward the end of his career, he was Sterling Professor of Mathematical Sciences at Yale University, where he was the oldest professor in Yale's history to receive tenure.[10] Mandelbrot also held positions at the Pacific Northwest National Laboratory, Université Lille Nord de France, Institute for Advanced Study and Centre National de la Recherche Scientifique. During his career, he received over 15 honorary doctorates and served on many science journals, along with winning numerous awards. His autobiography, The Fractalist: Memoir of a Scientific Maverick, was published posthumously in 2012.

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. 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,Mandelbrot 开始研究被称为 Julia 集的分形,它们在复平面的某些变换下是不变的。在加斯顿 · 朱莉娅和皮埃尔 · 法图之前工作的基础上,曼德尔布洛特使用计算机绘制了朱莉娅集合的图像。在研究这些 Julia 集的拓扑结构时,他研究了他在1979年提出的 Mandelbrot 集。1982年,曼德布洛特在《自然的分形几何》一书中扩展和更新了他的观点。这一有影响力的工作带来了分形进入主流的专业和流行数学,以及沉默批评家,谁曾驳回分形作为“程序人工制品”。

曼德布洛特谈到了[2006年他在法国荣誉军团勋章的获奖感言中谈到了曼德布洛特集合]

Mandelbrot was born in a Jewish family, in Warsaw during the Second Polish Republic. His father made his living trading clothing; his mother was a dental surgeon. During his first two school years, he was tutored privately by an uncle who despised rote learning: "Most of my time was spent playing chess, reading maps and learning how to open my eyes to everything around me."[11] Later, the family's move to France, the war, and his acquaintance with his father's brother, the mathematician Szolem Mandelbrojt who had moved to Paris around 1920, further prevented a standard education.


In 1975, Mandelbrot coined the term fractal to describe these structures and first published his ideas, and later translated, Fractals: Form, Chance and Dimension. 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". 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这个术语来描述这些结构,并首次发表了他的观点,后来被翻译成分形: 形式、机会和维度。计算机科学家、物理学家斯蒂芬•沃尔夫拉姆(Stephen Wolfram)表示,这本书对曼德布洛特来说是一个“突破” ,在此之前,他通常会“将相当简单的数学应用到以前几乎没有认真研究过数学的领域”。沃尔夫勒姆补充说,由于这项新研究的结果,他不再是一个“流浪的科学家” ,后来称他为“分形之父” :

The family emigrated from Poland to France in 1936, when he was 11. "The fact that my parents, as economic and political refugees, joined Szolem in France saved our lives," he writes.[6]:17[12] Mandelbrot attended the Lycée Rolin in Paris until the start of World War II, when his family moved to Tulle, France. He was helped by Rabbi David Feuerwerker, the Rabbi of Brive-la-Gaillarde, to continue his studies.[6]:62–63[13] Much of France was occupied by the Nazis at the time, and Mandelbrot recalls this period:

}

曼德布洛特创立了有史以来第一个“粗糙理论” ,他看到了山脉、海岸线和河流盆地形状的“粗糙” ,看到了植物、血管和肺的结构,看到了星系的聚集。他个人的追求是创造一些数学公式来衡量这些物体在自然界中的整体“粗糙度”

Randomness in financial markets

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.

在他题为《英国海岸有多长?统计自相似性和分维数1967年发表在《科学》杂志上,曼德尔布洛特讨论了自相似曲线,这些曲线都有豪斯多夫维数,是分形的例子,尽管曼德尔布洛特在论文中没有使用这个术语,因为他直到1975年才造出这个术语。这篇论文是曼德布洛特关于分形主题的首批出版物之一。

Mandelbrot saw financial markets as an example of "wild randomness", characterized by concentration and long range dependence. He developed several original approaches for modelling financial fluctuations.[14]

In his early work, he found that the price changes in financial markets did not follow a Gaussian distribution, but rather Lévy stable distributions having infinite variance. He found, for example, that cotton prices followed a Lévy stable distribution with parameter α equal to 1.7 rather than 2 as in a Gaussian distribution. "Stable" distributions have the property that the sum of many instances of a random variable follows the same distribution but with a larger scale parameter.[15]

Mandelbrot emphasized the use of fractals as realistic and useful models for describing many "rough" phenomena in the real world. He concluded that "real roughness is often fractal and can be measured." and a maverick. His informal and passionate style of writing and his emphasis on visual and geometric intuition (supported by the inclusion of numerous illustrations) made The Fractal Geometry of Nature accessible to non-specialists. The book sparked widespread popular interest in fractals and contributed to chaos theory and other fields of science and mathematics.

曼德布洛特强调用分形作为现实和有用的模型来描述现实世界中的许多“粗糙”现象。他的结论是: “真实的粗糙度通常是分形的,可以测量。”还是个特立独行的人。他非正式和充满激情的写作风格和他对视觉和几何直觉的强调(通过大量插图的支持)使得《自然的分形几何学》对非专业人士来说易于理解。这本书激发了人们对分形的广泛兴趣,并促成了混沌理论和其他领域的科学和数学。


Developing "fractal geometry" and the Mandelbrot set

Mandelbrot also put his ideas to work in cosmology. He offered in 1974 a new explanation of Olbers' paradox (the "dark night sky" riddle), demonstrating the consequences of fractal theory as a sufficient, but not necessary, resolution of the paradox. He postulated that if the stars in the universe were fractally distributed (for example, like Cantor dust), it would not be necessary to rely on the Big Bang theory to explain the paradox. His model would not rule out a Big Bang, but would allow for a dark sky even if the Big Bang had not occurred.

曼德布洛特也将他的想法应用于宇宙学。1974年,他对奥尔伯斯悖论(“黑暗的夜空”之谜)提出了新的解释,证明了分形理论的结果是解决这一悖论的充分而非必要的方法。他假设,如果宇宙中的恒星是分散分布的(例如,康托尔尘埃) ,就没有必要依靠大爆炸理论来解释这一悖论。他的模型不能排除宇宙大爆炸的可能性,但是即使宇宙大爆炸没有发生,也可以考虑到黑暗的天空。

The small asteroid 27500 Mandelbrot was named in his honor. In November 1990, he was made a Chevalier in France's Legion of Honour. In December 2005, Mandelbrot was appointed to the position of Battelle Fellow at the Pacific Northwest National Laboratory. Mandelbrot was promoted to an Officer of the Legion of Honour in January 2006. An honorary degree from Johns Hopkins University was bestowed on Mandelbrot in the May 2010 commencement exercises.

Wolfram briefly describes fractals as a form of geometric repetition, "in which smaller and smaller copies of a pattern are successively nested inside each other, so that the same intricate shapes appear no matter how much you zoom in to the whole. Fern leaves and Romanesco broccoli are two examples from nature."[8] He points out an unexpected conclusion:

Mandelbrot used the term "fractal" as it derived from the Latin word "fractus", defined as broken or shattered glass. Using the newly developed IBM computers at his disposal, Mandelbrot was able to create fractal images using graphic computer code, images that an interviewer described as looking like "the delirious exuberance of the 1960s psychedelic art with forms hauntingly reminiscent of nature and the human body". He also saw himself as a "would-be Kepler", after the 17th-century scientist Johannes Kepler, who calculated and described the orbits of the planets.[18]


A Mandelbrot set

Mandelbrot, however, never felt he was inventing a new idea. He describes his feelings in a documentary with science writer Arthur C. Clarke:

   /* @noflip */
   padding-left: 1.6em;
   margin-top: 0;

}


According to Clarke, "the Mandelbrot set is indeed one of the most astonishing discoveries in the entire history of mathematics. Who could have dreamed that such an incredibly simple equation could have generated images of literally infinite complexity?" Clarke also notes an "odd coincidence

the name Mandelbrot, and the word "mandala"—for a religious symbol—which I'm sure is a pure coincidence, but indeed the Mandelbrot set does seem to contain an enormous number of mandalas.[19]


Mandelbrot left IBM in 1987, after 35 years and 12 days, when IBM decided to end pure research in his division.[20] He joined the Department of Mathematics at Yale, and obtained his first tenured post in 1999, at the age of 75.[21] At the time of his retirement in 2005, he was Sterling Professor of Mathematical Sciences.


Fractals and the "theory of roughness"

Mandelbrot created the first-ever "theory of roughness", and he saw "roughness" in the shapes of mountains, coastlines and river basins; the structures of plants, blood vessels and lungs; the clustering of galaxies. His personal quest was to create some mathematical formula to measure the overall "roughness" of such objects in nature.[6]:xi He began by asking himself various kinds of questions related to nature:

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.[22][23]


Mandelbrot emphasized the use of fractals as realistic and useful models for describing many "rough" phenomena in the real world. He concluded that "real roughness is often fractal and can be measured."[6]:296 Although Mandelbrot coined the term "fractal", some of the mathematical objects he presented in The Fractal Geometry of Nature had been previously described by other mathematicians. Before Mandelbrot, however, they were regarded as isolated curiosities with unnatural and non-intuitive properties. Mandelbrot brought these objects together for the first time and turned them into essential tools for the long-stalled effort to extend the scope of science to explaining non-smooth, "rough" objects in the real world. His methods of research were both old and new:

   /* @noflip */
   padding-left: 1.6em;
   margin-top: 0;

}


Fractals are also found in human pursuits, such as music, painting, architecture, and stock market prices. Mandelbrot believed that fractals, far from being unnatural, were in many ways more intuitive and natural than the artificially smooth objects of traditional Euclidean geometry:

Clouds are not spheres, mountains are not cones, coastlines are not circles, and bark is not smooth, nor does lightning travel in a straight line.
  —Mandelbrot, in his introduction to The Fractal Geometry of Nature

Section of a Mandelbrot set


Mandelbrot has been called an artist, and a visionary[24] and a maverick.[25] His informal and passionate style of writing and his emphasis on visual and geometric intuition (supported by the inclusion of numerous illustrations) made The Fractal Geometry of Nature accessible to non-specialists. The book sparked widespread popular interest in fractals and contributed to chaos theory and other fields of science and mathematics.


Mandelbrot died from pancreatic cancer at the age of 85 in a hospice in Cambridge, Massachusetts on 14 October 2010. Reacting to news of his death, mathematician Heinz-Otto Peitgen said: "[I]f we talk about impact inside mathematics, and applications in the sciences, he is one of the most important figures of the last fifty years." Nicolas Sarkozy, President of France at the time of Mandelbrot's death, said Mandelbrot had "a powerful, original mind that never shied away from innovating and shattering preconceived notions [... h]is work, developed entirely outside mainstream research, led to modern information theory." Mandelbrot's obituary in The Economist points out his fame as "celebrity beyond the academy" and lauds him as the "father of fractal geometry".

2010年10月14日,曼德尔布洛特在马萨诸塞州剑桥的一家临终关怀胰腺癌去世,享年85岁。数学家海因茨-奥托 · 佩特根在听到他去世的消息后说: “如果我们谈论数学内部的影响,以及在科学中的应用,他是过去50年来最重要的人物之一。”曼德布洛特去世时的法国总统尼古拉•萨科齐(Nicolas Sarkozy)表示,曼德布洛特“拥有强大的、独创的头脑,从不回避创新和打破先入为主的观念[ ... ... 他是工作,完全在主流研究之外发展起来,导致了现代信息理论的产生。”曼德布洛特在《经济学人》上发表的讣告指出,他是“学术之外的名人” ,并称赞他是“分形几何之父”。

Mandelbrot also put his ideas to work in cosmology. He offered in 1974 a new explanation of Olbers' paradox (the "dark night sky" riddle), demonstrating the consequences of fractal theory as a sufficient, but not necessary, resolution of the paradox. He postulated that if the stars in the universe were fractally distributed (for example, like Cantor dust), it would not be necessary to rely on the Big Bang theory to explain the paradox. His model would not rule out a Big Bang, but would allow for a dark sky even if the Big Bang had not occurred.[26]


Best-selling essayist-author Nassim Nicholas Taleb has remarked that Mandelbrot's book The (Mis)Behavior of Markets is in his opinion "The deepest and most realistic finance book ever published".

最畅销的散文作家兼作家纳西姆·尼可拉斯·塔雷伯 · 曼德布洛特评论说,曼德布洛特的著作《市场的(错误)行为》是他认为“有史以来最深刻、最现实的金融著作”。

Awards and honors

Mandelbrot's awards include the Wolf Prize for Physics in 1993, the Lewis Fry Richardson Prize of the European Geophysical Society in 2000, the Japan Prize in 2003,[27] and the Einstein Lectureship of the American Mathematical Society in 2006.

He referred to himself as a "fractalist" 伯努瓦 b。在用法语说话时,曼德布洛特宣布了他的名字。| group = n }(1924年11月20日至2010年10月14日)是波兰出生的法国和美国数学家和博学家,对实用科学有着广泛的兴趣,特别是对他所称的物理现象的”粗糙艺术”和”生活中不受控制的元素”。他说自己是个“分裂主义者” | last1 = Gomory | first1 = R. | authorlink1 = Ralph E. Gomory 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,当曼德布洛特还是个孩子的时候,他的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,并在加利福尼亚理工学院获得了航空学硕士学位。他的大部分职业生涯都在美国和法国度过,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,在那里他成为了 IBM 研究员,并定期休假到哈佛大学教书。在哈佛大学,他发表了关于美国商品市场与棉花期货的研究成果之后,他开始教授经济学和应用科学。 | title = Benoît Mandelbrot (1924–2010) | doi = 10.1038/468378a 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", like clouds or shorelines, actually had a "degree of order". 由于可以访问 IBM 的计算机,曼德尔布洛特是第一个使用计算机图形学图形来创建和显示分形几何图形的人,这导致了他在1980年发现了曼德尔布洛特集合。他展示了如何从简单的规则中创造出视觉的复杂性。他说,通常被认为是“粗糙”、“混乱”或“混乱”的事物,如云或海岸线,实际上有一定程度的秩序。 | journal = Nature | volume = 468 Toward the end of his career, he was Sterling Professor of Mathematical Sciences at Yale University, where he was the oldest professor in Yale's history to receive tenure. Mandelbrot also held positions at the Pacific Northwest National Laboratory, Université Lille Nord de France, Institute for Advanced Study and Centre National de la Recherche Scientifique. During his career, he received over 15 honorary doctorates and served on many science journals, along with winning numerous awards. His autobiography, The Fractalist: Memoir of a Scientific Maverick, was published posthumously in 2012. 在他职业生涯的最后阶段,他是耶鲁大学数学科学系的斯特林教席,也是耶鲁历史上获得终身教职的最年长的教授。曼德布洛特还在太平洋西北国家实验室、法国里尔北方的大学、高级研究所和法国国家科学研究中心担任过职务。在他的职业生涯中,他获得了超过15个荣誉博士学位,并在许多科学期刊上服务,同时还获得了许多奖项。他的自传《分析家: 科学怪人的回忆录》在他死后于2012年出版。 | issue = 7322 | pages = 378 | year = 2010 Mandelbrot was born in a Jewish family, in Warsaw during the Second Polish Republic. His father made his living trading clothing; his mother was a dental surgeon. During his first two school years, he was tutored privately by an uncle who despised rote learning: "Most of my time was spent playing chess, reading maps and learning how to open my eyes to everything around me." Later, the family's move to France, the war, and his acquaintance with his father's brother, the mathematician Szolem Mandelbrojt who had moved to Paris around 1920, further prevented a standard education. 曼德布洛特出生于第二波兰共和国时期的华沙的一个犹太家庭。他的父亲靠卖衣服为生,母亲是牙科医生。在他的头两个学年里,他的一位叔叔私下辅导他,他鄙视死记硬背: “我的大部分时间都花在下棋、看地图和学习如何睁开眼睛看我周围的一切。”后来,他们全家搬到了法国,战争爆发,他和父亲的兄弟,数学家 Szolem Mandelbrojt 相识,后者在1920年前后移居巴黎,这进一步阻碍了他接受标准教育。 | pmid = 21085164 |bibcode = 2010Natur.468..378G | s2cid = 4393964 The family emigrated from Poland to France in 1936, when he was 11. "The fact that my parents, as economic and political refugees, joined Szolem in France saved our lives," he writes. Mandelbrot attended the Lycée Rolin in Paris until the start of World War II, when his family moved to Tulle, France. He was helped by Rabbi David Feuerwerker, the Rabbi of Brive-la-Gaillarde, to continue his studies. Much of France was occupied by the Nazis at the time, and Mandelbrot recalls this period: 1936年,当他11岁的时候,他们一家从波兰移民到法国。他写道: “我的父母作为经济和政治难民加入了 Szolem,这一事实挽救了我们的生命。”。曼德布洛特曾在巴黎的 Lycée Rolin 工作,直到二战爆发,他的家人搬到了法国的图勒。他在布里夫拉盖亚尔德的犹太教教士 David Feuerwerker 的帮助下继续学业。当时法国大部分地区都被纳粹占领,曼德布洛特回忆起这段时期: }}
