Boltzmann, Ludwig Eduard Boltzmann, Ludwig Eduard (szül. 1844. febr. 20. Bécs - megh. 1906. szept. 5. Duino, Olaszország), fizikus, legnagyobb eredményeit a statisztikus mechanika kidolgozásában érte el. A statisztikus mechanika megmagyarázza és elôrejelzi, hogyan határozzák meg az atomok tulajdonságai (mint a tömeg, töltés és szerkezet) az anyag látható tulajdonságait (mint a viszkozitás, hôvezetés és diffúzió). 1866-ban a Bécsi Egyetemen doktorált, majd matematika- és fizikaprofesszor volt Bécsben, Grazban, Münchenben és Lipcsében. A kontinensen az elsô tudósok közé tartozott, akik felismerték a skót James Clerk Maxwell által javasolt elektromágneses elmélet jelentôségét. Statisztikus mechanikai munkáját erôsen támadták és sokáig félrertették, következtetéseit végül a kevéssel 1900 elôtt kezdôdô atomfizikai felfedezések támasztották alá, valamint az a felismerés, hogy az olyan fluktuációs jelenségek, mint a Brown-mozgás (a folyadékban lebegô mikroszkópikus részecskék véletlen mozgása), csak a statisztikus mechanika alapján magyarázhatók meg. 1866: A Bécsi Egyetemen doktorátust szerez a kinetikus gázelmélet témakörében, Josef Stefannál.

Back Issues Ludwig Boltzmann and Entropy Sriram Ramaswamy So what did Boltzmann do? l He defined entropy as log W, where W is the number of microstates accessible to the system. From this definition flows all of thermodynamics and statistical physics. l He explained in statistical terms the second law of thermodynamics, i.e., that entropy must in general increase for an isolated system, and showed how such `irreversible' behaviour could follow from the time-symmetric laws of mechanics. l He constructed an approximate but very useful model (the Boltzmann transport equation) to describe how the distribution of positions and velocities of the particles of a gas evolves in time under flow and collisions. l His work, in particular the idea of counting microstates, relied in a fundamental way on the idea that matter was composed of discrete atoms. Its success, and his impassioned defence of these ideas, established atomism once and for all. Below, I summarise briefly the course of Boltz-mann's life and work. More on the subject can be found in the various `entropy articles' in this special issue dedicated to him, as well as in others to which I refer at the end.

Boltzmann, Ludwig Eduard (1844-1906) Físico austríaco, estabeleceu as bases da física clássica estatística, e relacionou a teoria cinética à termodinâmica. Boltzmann foi criado em Wels e Linz, onde seu pai era funcionário, trabalhando no setor de impostos. Ele obteve seu doutorado em Viena, em 1866, e foi professor, ao longo de sua carreira em Graz, Viena, Munich e Leipzig. A física teórica sofreu mudanças importantes nos anos 1860-1870, após o estabelecimento da Segunda Lei da Termodinâmica, efetuado por Clausius e Kelvin; da teoria cinética dos gases por Clausius e Maxwell e da teoria do eletromagnetismo por Maxwell. Botzmann estendeu a teoria cinética, desenvolvendo a lei de equipartição da energia das partículas pelos graus de liberdade, e calculando quantas partículas possuem uma determinada energia, originando a chamada distribuição de Maxwell-Boltzmann. Além disso Boltzmann utilizou a mecânica e estatística no estudo de sistemas contendo um grande número de partículas, e para a definição da energia térmica e da entropia (medida da desordem do sistema). Ele mostrou que a entropia (S)de um sistema está relacionada à probabilidade (W), que depende do número de modos em que o sistema pode ser constituído, de acordo com a expressão S = k.log(W), chamada equação de Boltzmann. Outra contribuição importante esteve relacionada a uma nova derivação da Lei de Stephan da radiação térmica emitida por emissores ideais, chamados "corpos-negros". Boltzmann também realizou diversos trabalhos sobre o eletromagnetismo.

Ludwig Boltzmann at Clark Ludwig Boltzmann was awarded an honorary degree by Clark University in 1899. This year coincided with Clark's 10th anniversary. Boltzmann's reply to his award is given below Boltzmann also gave four talks on the principles and basic equations of mechanics. These talks are currently being translated from German into English. To honor Boltzmann's work and his visit to Clark, a honorary degree was awarded to Joel Lebowitz , a recipient of the Boltzmann medal , on May 23, 1999. Boltzmann's reply The problem of science is a twofold one: first, to advance our knowledge of nature independently of any practical application; and second, to make practical applications of the knowledge gained. Although to a superficial observer it may seem that the latter is of greater importance, the development of humanity has shown in the most convincing way that the first kind of activity is not only of paramount importance, but that the leading role belongs to it. In fact, it is only thanks to the pioneers of science who, laying aside all practical applications, penetrate deeper and deeper into the essence and arrangement of the forces of nature, that humanity has obtained that sway over the laws of nature which makes possible the present practical achievements. The German universities have devoted themselves at all times to the nurture of pure science apart from its practical applications, although but one of the four university faculties is consecrated to it, and that one not entirely. It must be considered as a good omen, therefore, that here in America, which is usually taken to be the land of practical men, the ideal of a place entirely consecrated to the service of pure science, unattainable in Germany, has found its realization, so that I, who am body and soul a German professor, deem it a great honor to have conferred on me in this place, the greatest distinction which the University can grant. While desiring Clark University to flourish and thrive in the intimate conviction that the whole scientific world is interested in her prosperity, I express my thanks to the President and all its members for the high honor bestowed upon me today.

Er hatte dabei zahlreiche Fachgenossen seiner Zeit als Gegner, unter ihnen Wilhelm Ostwald und Max Planck . Dieser griff jedoch bei seinem Plancksches Strahlungsgesetz auf die Vorstellungen Boltzmanns zurück. Das Stefan-Boltzmann-Gesetz (die ausgestrahlte Leistung ist der 4. Potenz der absoluten Temperatur proportional) ist ein Sonderfall des Planckschen Gesetzes.
