Ludwig Eduard Boltzmann (German pronunciation: [ˈluːtvɪg ˈbɔlt͡sman]; February 20, 1844 – September 5, 1906) was an Austrian physicist and philosopher. His greatest achievements were the development of statistical mechanics, and the statistical explanation of the second law of thermodynamics. In 1877 he provided the current definition of entropy, [math]\displaystyle{ S = k_{\rm B} \ln \Omega \! }[/math], interpreted as a measure of statistical disorder of a system. Max Planck named the constant, k_B, the Boltzmann constant.

路德维希·爱德华·玻尔兹曼（1844年2月20日—1906年9月5日），奥地利物理学家、哲学家。他最伟大的功绩是发展了统计力学，并且从统计意义出发解释了热力学第二定律。1877年，他给出了目前熵的定义，即玻尔兹曼熵公式：[math]\displaystyle{ S = k_{\rm B} \ln \Omega \! }[/math]，将熵解释为系统统计无序性的度量。马克斯·普朗克命名k_B为玻尔兹曼常数。

Statistical mechanics is one of the pillars of modern physics. It describes how macroscopic observations (such as temperature and pressure) are related to microscopic parameters that fluctuate around an average. It connects thermodynamic quantities (such as heat capacity) to microscopic behavior, whereas, in classical thermodynamics, the only available option would be to measure and tabulate such quantities for various materials.

统计力学是现代物理学的支柱之一。它描述了宏观观察量(如温度和压力)如何与围绕平均值波动的微观参数相联系。它将热力学量(比如热容)与微观行为联系起来，而在经典热力学中，唯一可行的选择就是测量各种材料的热力学量，然后列成表格。

个人简介

童年时光与教育经历

Boltzmann was born in Erdberg, a suburb of Vienna. His father, Ludwig Georg Boltzmann, was a revenue official. His grandfather, who had moved to Vienna from Berlin, was a clock manufacturer, and Boltzmann's mother, Katharina Pauernfeind, was originally from Salzburg. He received his primary education at the home of his parents. Boltzmann attended high school in Linz, Upper Austria. When Boltzmann was 15, his father died.

玻尔兹曼出生在维也纳郊区的埃尔德伯格。祖父从柏林搬到维也纳，是一名钟表制造商。父亲路德维希·格奥尔格·玻尔兹曼是一名税务官员，母亲卡塔琳娜·波恩芬德来自萨尔茨堡。他在父母家里接受了初等教育。高中时光在上奥地利的林茨度过。玻尔兹曼15岁时，他的父亲去世了。

Starting in 1863, Boltzmann studied mathematics and physics at the University of Vienna. He received his doctorate in 1866 and his venia legendi in 1869. Boltzmann worked closely with Josef Stefan, director of the institute of physics. It was Stefan who introduced Boltzmann to Maxwell's work.

从1863年开始，玻尔兹曼在维也纳大学学习数学和物理。他于1866年获得博士学位，1869年获得venia legendi（任教资格）。波尔兹曼与物理研究所所长约瑟夫·斯特凡(Josef Stefan)密切合作。正是斯特凡把玻尔兹曼引入了麦克斯韦的研究。

学术生涯

In 1869 at age 25, thanks to a letter of recommendation written by Stefan, Boltzmann was appointed full Professor of Mathematical Physics at the University of Graz in the province of Styria. In 1869 he spent several months in Heidelberg working with Robert Bunsen and Leo Königsberger and in 1871 with Gustav Kirchhoff and Hermann von Helmholtz in Berlin. In 1873 Boltzmann joined the University of Vienna as Professor of Mathematics and there he stayed until 1876.

1869年，25岁的玻尔兹曼经斯特凡的推荐，被任命为斯蒂里亚省格拉茨大学的数学物理正教授。1869年，他在海德堡与罗伯特·本森和里奥·柯尼斯堡一起工作数月，1871年在柏林与古斯塔夫·基尔霍夫和赫尔曼·冯·赫姆霍尔兹一起工作。1873年玻尔兹曼加入维也纳大学担任数学教授，直至1876年。

In 1872, long before women were admitted to Austrian universities, he met Henriette von Aigentler, an aspiring teacher of mathematics and physics in Graz. She was refused permission to audit lectures unofficially. Boltzmann supported her decision to appeal, which was successful. On July 17, 1876 Ludwig Boltzmann married Henriette; they had three daughters: Henriette (1880), Ida (1884) and Else (1891); and a son, Arthur Ludwig (1881). Boltzmann went back to Graz to take up the chair of Experimental Physics. Among his students in Graz were Svante Arrhenius and Walther Nernst. He spent 14 happy years in Graz and it was there that he developed his statistical concept of nature.

1872年，远在女性可以被奥地利大学录取之前，他遇到了亨里埃特·冯·艾根特勒，这是一位有抱负的格拉茨数学和物理女教师。然而她被拒绝旁听大学讲座。玻尔兹曼支持她上诉的决定，之后上诉成功。1876年7月17日，路德维希·玻尔兹曼与亨里埃特结婚；他们共育有三女一子：亨里埃特(1880年)、艾达(1884年)、爱尔莎(1891年)、亚瑟·路德维希(1881年)。玻尔兹曼回到格拉茨担任实验物理学的主席。他在格拉茨的学生中有斯凡特·阿伦尼乌斯和瓦尔特·能斯特。

他在格拉茨度过了快乐的14年，正是在那里，他发展了他的自然界的统计概念。

Boltzmann was appointed to the Chair of Theoretical Physics at the University of Munich in Bavaria, Germany in 1890.

玻尔兹曼于1890年被任命为德国巴伐利亚慕尼黑大学理论物理学主席。

In 1894, Boltzmann succeeded his teacher Joseph Stefan as Professor of Theoretical Physics at the University of Vienna.

1894年，波尔兹曼接替他的老师约瑟夫·斯特凡成为维也纳大学理论物理学教授。

晚年生活与逝世缘由

Boltzmann spent a great deal of effort in his final years defending his theories. He did not get along with some of his colleagues in Vienna, particularly Ernst Mach, who became a professor of philosophy and history of sciences in 1895. That same year Georg Helm and Wilhelm Ostwald presented their position on energetics at a meeting in Lübeck. They saw energy, and not matter, as the chief component of the universe. Boltzmann's position carried the day among other physicists who supported his atomic theories in the debate. In 1900, Boltzmann went to the University of Leipzig, on the invitation of Wilhelm Ostwald. Ostwald offered Boltzmann the professorial chair in physics, which became vacant when Gustav Heinrich Wiedemann died. After Mach retired due to bad health, Boltzmann returned to Vienna in 1902. In 1903, Boltzmann, together with Gustav von Escherich and Emil Müller, founded the Austrian Mathematical Society. His students included Karl Přibram, Paul Ehrenfest and Lise Meitner.

晚年的玻尔兹曼致力于维护自己所创立的理论。在维也纳，他和一些同事相处不很融洽，尤其是恩斯特·马赫(Ernst Mach，1895年成为哲学和科学史教授)。1895年，格奥尔格·赫尔姆（Georg Helm）和威廉·奥斯特瓦尔德（Wilhelm Ostwald）在吕贝克的一次会议上提出了他们关于能量学的观点。他们认为宇宙的主要组成部分是能量，而不是物质。会议辩论中玻尔兹曼的观点赢得了其他支持原子理论的物理学家的赞同。在威廉·奥斯特瓦尔德的邀请下，玻尔兹曼于1900年前往莱比锡大学，填补辞世的古斯塔夫·海因里希·维德曼留下的空缺，出任物理学首席教授。在马赫因健康原因退休以后，玻尔兹曼于1902年返回维也纳。1903年，玻尔兹曼与古斯塔夫·冯·埃舍里希、埃米尔·穆勒一同创立了奥地利数学学会。他的门生包括：卡尔·普里贝拉姆（经济学家），保罗·埃伦费斯特（理论物理学家），丽斯·迈特纳（物理学家，被爱因斯坦称为“德国居里夫人”）。

In Vienna, Boltzmann taught physics and also lectured on philosophy. Boltzmann's lectures on natural philosophy were very popular and received considerable attention. His first lecture was an enormous success. Even though the largest lecture hall had been chosen for it, the people stood all the way down the staircase. Because of the great successes of Boltzmann's philosophical lectures, the Emperor invited him for a reception at the Palace.

在维也纳大学，玻尔兹曼教授物理和哲学。他有关自然哲学的讲座颇受欢迎。开课当天，即使已经事先安排了最大的讲堂，现场依然是座无虚席，观者如山。讲座取得巨大成功，轰动全国，奥匈帝国皇帝也邀请玻尔兹曼入宫进行招待。

In 1906, Boltzmann's deteriorating mental condition forced him to resign his position, and his symptoms indicate he experienced what would today be diagnosed as bipolar disorder. Four months later he died by suicide on September 5, 1906, by hanging himself while on vacation with his wife and daughter in Duino, near Trieste (then Austria).

1906年，玻尔兹曼日渐恶化的精神状况迫使他辞去教职。后人对他当时的症状进行分析得出了躁郁症的结论。四个月后，在和妻女的度假过程中，他选择上吊自杀结束自己的痛苦和生命，终年63岁。

He is buried in the Viennese Zentralfriedhof. His tombstone bears the inscription of Boltzmann's entropy formula: [math]\displaystyle{ S = k \cdot \log W }[/math]

他被葬在维也纳中央弗里德霍夫博物馆。墓碑上刻着玻尔兹曼熵公式: [math]\displaystyle{ S = k \cdot \log W }[/math]

Philosophy

模板:Unreferenced section Boltzmann's kinetic theory of gases seemed to presuppose the reality of atoms and molecules, but almost all German philosophers and many scientists like Ernst Mach and the physical chemist Wilhelm Ostwald disbelieved their existence. During the 1890s, Boltzmann attempted to formulate a compromise position which would allow both atomists and anti-atomists to do physics without arguing over atoms. His solution was to use Hertz's theory that atoms were Bilder, that is, models or pictures. Atomists could think the pictures were the real atoms while the anti-atomists could think of the pictures as representing a useful but unreal model, but this did not fully satisfy either group. Furthermore, Ostwald and many defenders of "pure thermodynamics" were trying hard to refute the kinetic theory of gases and statistical mechanics because of Boltzmann's assumptions about atoms and molecules and especially statistical interpretation of the second law of thermodynamics.

玻尔兹曼的气体动力学理论似乎假定了原子和分子的真实性，但几乎所有的德国哲学家和许多科学家，如恩斯特·马赫(Ernst Mach)和物理化学家威廉·奥斯特瓦尔德(Wilhelm Ostwald)，都不相信它们的存在。在19世纪90年代，玻尔兹曼试图形成一个折中立场，使原子主义者和反原子主义者都可以在不争论原子存在与否的情况下研究物理学。他的解决方案是使用赫兹的理论，即原子是Bilder，即模型或图片。原子论者可以认为这些图像是真实的原子，而反原子论者则认为这些图像代表了一种有用但不真实的模型，然而这两类人都不完全满意。此外，由于玻尔兹曼关于原子和分子真实存在的假设，特别是对于热力学第二定律的统计解释，奥斯特瓦尔德和许多“纯热力学”的捍卫者试图努力驳斥气体动力学理论和统计力学。

Around the turn of the century, Boltzmann's science was being threatened by another philosophical objection. Some physicists, including Mach's student, Gustav Jaumann, interpreted Hertz to mean that all electromagnetic behavior is continuous, as if there were no atoms and molecules, and likewise as if all physical behavior were ultimately electromagnetic. This movement around 1900 deeply depressed Boltzmann since it could mean the end of his kinetic theory and statistical interpretation of the second law of thermodynamics.

在世纪之交，玻尔兹曼的理论受到了另一种哲学异议的威胁。一些物理学家，包括马赫的学生古斯塔夫·乔曼，把赫兹的理论解释为所有的电磁行为都是连续的，就好像没有原子和分子的存在，同样所有的物理行为最终都是电磁性质的。1900年左右的这一运动使玻尔兹曼深感沮丧，因为它可能意味着他的动力学理论和热力学第二定律的统计解释的终结。

After Mach's resignation in Vienna in 1901, Boltzmann returned there and decided to become a philosopher himself to refute philosophical objections to his physics, but he soon became discouraged again. In 1904 at a physics conference in St. Louis most physicists seemed to reject atoms and he was not even invited to the physics section. Rather, he was stuck in a section called "applied mathematics", he violently attacked philosophy, especially on allegedly Darwinian grounds but actually in terms of Lamarck's theory of the inheritance of acquired characteristics that people inherited bad philosophy from the past and that it was hard for scientists to overcome such inheritance.

1901年马赫在维也纳辞职后，玻尔兹曼回到学校，并决定自己成为一名哲学家，以驳斥哲学上对物理学的异议，但他很快又受到了打击。1904年，在圣路易斯举行的一次物理会议上，大多数物理学家似乎都拒绝接受原子，他甚至没有被邀请参加物理部分。相反，他被困在“应用数学”的讨论会，他猛烈地攻击哲学，特别是在所谓的达尔文主义的基础上，但实际上是根据拉马克的后天特征遗传理论，人们从过去继承了糟糕的哲学，科学家很难克服这种遗传（感觉这句话最后部分很奇怪，希望有大佬帮助看看）。

In 1905 Boltzmann corresponded extensively with the Austro-German philosopher Franz Brentano with the hope of gaining a better mastery of philosophy, apparently, so that he could better refute its relevancy in science, but he became discouraged about this approach as well.

1905年，玻尔兹曼与德-奥哲学家弗朗茨·布伦塔诺进行了广泛的通信，希望能更好地掌握哲学，显然，这样他就能更好地驳斥哲学在科学上的相关性，但他对这种方法也逐渐感到沮丧。

Physics

Boltzmann's most important scientific contributions were in kinetic theory, including for motivating the Maxwell–Boltzmann distribution as a description of molecular speeds in a gas. Maxwell–Boltzmann statistics and the Boltzmann distribution remain central in the foundations of classical statistical mechanics. They are also applicable to other phenomena that do not require quantum statistics and provide insight into the meaning of temperature.

玻尔兹曼最重要的科学贡献是在动力学理论上，包括推动应用麦克斯韦-玻尔兹曼分布描述气体中分子的速度。直至今日，麦克斯韦-玻尔兹曼统计和玻尔兹曼分布仍然是经典统计力学基石之一。他们也适用于解释其他不需要量子统计的现象，另外提供关于温度内涵的洞见。

Most chemists, since the discoveries of John Dalton in 1808, and James Clerk Maxwell in Scotland and Josiah Willard Gibbs in the United States, shared Boltzmann's belief in atoms and molecules, but much of the physics establishment did not share this belief until decades later. Boltzmann had a long-running dispute with the editor of the preeminent German physics journal of his day, who refused to let Boltzmann refer to atoms and molecules as anything other than convenient theoretical constructs. Only a couple of years after Boltzmann's death, Perrin's studies of colloidal suspensions (1908–1909), based on Einstein's theoretical studies of 1905, confirmed the values of Avogadro's number and Boltzmann's constant, convincing the world that the tiny particles really exist.

自1808年，约翰·道尔顿(John Dalton)提出原子理论以来、包括詹姆斯·克拉克·麦克斯韦（苏格兰）(James Clerk Maxwell)和乔赛亚·威拉德·吉布斯（美）(Josiah Willard Gibbs)在内，大多数化学家都认同玻尔兹曼对原子和分子的看法，但很多物理学家直到几十年后才认同这一观点。玻尔兹曼与当时著名的德国物理学杂志的编辑有长期的争执，后者拒绝让玻尔兹曼将原子和分子作为方便的理论结构之外的任何东西。玻尔兹曼去世几年后，佩兰基于爱因斯坦1905年的理论研究，对胶体悬浮液进行了研究(1908-1909)，证实了阿伏伽德罗数和玻尔兹曼常数的值，使世界相信微小粒子确实存在。

To quote Planck, "The logarithmic connection between entropy and probability was first stated by L. Boltzmann in his kinetic theory of gases". This famous formula for entropy S is

[math]\displaystyle{ S = k_B \ln W }[/math]

where k_B is Boltzmann's constant, and ln is the natural logarithm. W is Wahrscheinlichkeit, a German word meaning the probability of occurrence of a macrostate or, more precisely, the number of possible microstates corresponding to the macroscopic state of a system — the number of (unobservable) "ways" in the (observable) thermodynamic state of a system that can be realized by assigning different positions and momenta to the various molecules. Boltzmann's paradigm was an ideal gas of N identical particles, of which N_i are in the ith microscopic condition (range) of position and momentum. W can be counted using the formula for permutations

[math]\displaystyle{ W = N! \prod_i \frac{1}{N_i!} }[/math]

where i ranges over all possible molecular conditions, and where [math]\displaystyle{ ! }[/math] denotes factorial. The "correction" in the denominator account for indistinguishable particles in the same condition.

普朗克曾说：“熵和概率之间的对数联系是由玻尔兹曼在他的气体动力学理论中首次提出的”。也就是著名的熵公式：[math]\displaystyle{ S = k_B \ln W }[/math]，其中k_B 是玻尔兹曼常数，W 代表德文中宏观状态出现的概率，更准确一些来说，是对应于系统宏观状态的可能微观状态的数量——在一个系统的(可观察的)热力学状态下的(不可观测的)“方式”的数量，可以通过分配不同的位置和动量给不同的分子来实现。玻尔兹曼的范式是N个相同粒子的理想气体，其中Ni处于第i个微观位置和动量条件(范围)。W 可以用排列公式计算：[math]\displaystyle{ W = N! \prod_i \frac{1}{N_i!} }[/math]，其中i 的范围包含所有可能的分子状态，[math]\displaystyle{ ! }[/math]代表阶乘。分母中的“修正”解释了相同条件下难以区分的粒子。

Boltzmann could also be considered one of the forerunners of quantum mechanics due to his suggestion in 1877 that the energy levels of a physical system could be discrete.

玻尔兹曼也被认为是量子力学的先驱之一，因为他在1877年提出了物理系统的能级可以是离散的。

Boltzmann equation

Boltzmann's bust in the courtyard arcade of the main building, University of Vienna.

Main article: Boltzmann equation

The Boltzmann equation was developed to describe the dynamics of an ideal gas.

建立玻尔兹曼方程是用来描述理想气体的动力学规律的。

[math]\displaystyle{ \frac{\partial f}{\partial t}+ v \frac{\partial f}{\partial x}+ \frac{F}{m} \frac{\partial f}{\partial v} = \frac{\partial f}{\partial t}\left.{\!\!\frac{}{}}\right|_\mathrm{collision} }[/math]

where ƒ represents the distribution function of single-particle position and momentum at a given time (see the Maxwell–Boltzmann distribution), F is a force, m is the mass of a particle, t is the time and v is an average velocity of particles.

其中 ƒ 代表某一时刻单个粒子位置和动量的函数分布（见麦克斯韦-玻尔兹曼方程），F 代表力，m 代表粒子的质量，t 是时间，v 是粒子的平均速度。

This equation describes the temporal and spatial variation of the probability distribution for the position and momentum of a density distribution of a cloud of points in single-particle phase space. (See Hamiltonian mechanics.) The first term on the left-hand side represents the explicit time variation of the distribution function, while the second term gives the spatial variation, and the third term describes the effect of any force acting on the particles. The right-hand side of the equation represents the effect of collisions.

In principle, the above equation completely describes the dynamics of an ensemble of gas particles, given appropriate boundary conditions. This first-order differential equation has a deceptively simple appearance, since ƒ can represent an arbitrary single-particle distribution function. Also, the force acting on the particles depends directly on the velocity distribution function ƒ. The Boltzmann equation is notoriously difficult to integrate. David Hilbert spent years trying to solve it without any real success.

The form of the collision term assumed by Boltzmann was approximate. However, for an ideal gas the standard Chapman–Enskog solution of the Boltzmann equation is highly accurate. It is expected to lead to incorrect results for an ideal gas only under shock wave conditions.

Boltzmann tried for many years to "prove" the second law of thermodynamics using his gas-dynamical equation — his famous H-theorem. However the key assumption he made in formulating the collision term was "molecular chaos", an assumption which breaks time-reversal symmetry as is necessary for anything which could imply the second law. It was from the probabilistic assumption alone that Boltzmann's apparent success emanated, so his long dispute with Loschmidt and others over Loschmidt's paradox ultimately ended in his failure.

Finally, in the 1970s E.G.D. Cohen and J. R. Dorfman proved that a systematic (power series) extension of the Boltzmann equation to high densities is mathematically impossible. Consequently, nonequilibrium statistical mechanics for dense gases and liquids focuses on the Green–Kubo relations, the fluctuation theorem, and other approaches instead.

Second thermodynamics law as a law of disorder

Boltzmann's grave in the Zentralfriedhof, Vienna, with bust and entropy formula.

The idea that the second law of thermodynamics or "entropy law" is a law of disorder (or that dynamically ordered states are "infinitely improbable") is due to Boltzmann's view of the second law of thermodynamics.

In particular, it was Boltzmann's attempt to reduce it to a stochastic collision function, or law of probability following from the random collisions of mechanical particles. Following Maxwell, Boltzmann modeled gas molecules as colliding billiard balls in a box, noting that with each collision nonequilibrium velocity distributions (groups of molecules moving at the same speed and in the same direction) would become increasingly disordered leading to a final state of macroscopic uniformity and maximum microscopic disorder or the state of maximum entropy (where the macroscopic uniformity corresponds to the obliteration of all field potentials or gradients). The second law, he argued, was thus simply the result of the fact that in a world of mechanically colliding particles disordered states are the most probable. Because there are so many more possible disordered states than ordered ones, a system will almost always be found either in the state of maximum disorder – the macrostate with the greatest number of accessible microstates such as a gas in a box at equilibrium – or moving towards it. A dynamically ordered state, one with molecules moving "at the same speed and in the same direction", Boltzmann concluded, is thus "the most improbable case conceivable...an infinitely improbable configuration of energy."

Boltzmann accomplished the feat of showing that the second law of thermodynamics is only a statistical fact. The gradual disordering of energy is analogous to the disordering of an initially ordered pack of cards under repeated shuffling, and just as the cards will finally return to their original order if shuffled a gigantic number of times, so the entire universe must some-day regain, by pure chance, the state from which it first set out. (This optimistic coda to the idea of the dying universe becomes somewhat muted when one attempts to estimate the timeline which will probably elapse before it spontaneously occurs.) The tendency for entropy increase seems to cause difficulty to beginners in thermodynamics, but is easy to understand from the standpoint of the theory of probability. Consider two ordinary dice, with both sixes face up. After the dice are shaken, the chance of finding these two sixes face up is small (1 in 36); thus one can say that the random motion (the agitation) of the dice, like the chaotic collisions of molecules because of thermal energy, causes the less probable state to change to one that is more probable. With millions of dice, like the millions of atoms involved in thermodynamic calculations, the probability of their all being sixes becomes so vanishingly small that the system must move to one of the more probable states. However, mathematically the odds of all the dice results not being a pair sixes is also as hard as the ones of all of them being sixes, and since statistically the data tend to balance, one in every 36 pairs of dice will tend to be a pair of sixes, and the cards -when shuffled- will sometimes present a certain temporary sequence order even if in its whole the deck was disordered.

Awards and honours

In 1885 he became a member of the Imperial Austrian Academy of Sciences and in 1887 he became the President of the University of Graz. He was elected a member of the Royal Swedish Academy of Sciences in 1888 and a Foreign Member of the Royal Society (ForMemRS) in 1899. Numerous things are named in his honour.
