Max Karl Ernst Ludwig Planck Por volta de 1942 Max Planck era um homem atormentado. Fazia 40 anos que suas descobertas científicas haviam aberto à física novos horizontes, permitindo um progresso vertiginoso na compreensão dos fenômenos subatômicos: agora, cientistas alemães, utilizando suas descobertas, propunham-se a construir o mais temível engenho bélico de todos os tempos: a bomba atômica. A Alemanha, porém, não conseguiu levá-la a termo. Isso foi feito pela América do Norte, que três anos mais tarde explodia o artefato sobre Hiroxima e Nagasáqui. E Max Planck viveu o bastante para testemunhar o triste acontecimento. Uma das grandes conquistas do início do século XIX foi a "redescoberta" da descontinuidade da matéria. Esta mostrava-se composta de "unidades", os átomos (ou as moléculas), entre os quais havia o vácuo. Coube a Planck estender o conceito de descontinuidade também à energia. Planck postulou que as trocas de energia entre átomos, ou, mais geralmente, entre corpos, não eram quantidades quaisquer. Parecia existir, para a energia, uma estrutura granular, pois as trocas faziam-se envolvendo quantidades bem determinadas. Isso foi a descoberta do caminho para o interior do átomo, para o conhecimento de sua estrutura e para a elucidação de fenômenos até então inexplicados; implicava também a existência, nele, de propriedades ainda não percebidas.

MAX KARL ERNST LUDWIG PLANCK Marjolein Van Butsel, 1C2, 2000-2001 Max Planck wurde am 23. April 1858 in Kiel geboren. Er war das vierte Kind von Johann Julius Wilhelm von Planck aus Göttingen, der in Kiel einen Lehrstuhl für Zivilprozessrecht (Bürgerrecht) hatte, und Emma Patzig von Greifswald. Außerdem hatte er noch zwei Stiefgeschwister von Wilhelm von Plancks erster Frau, Mathilde Voigt. Die Namen seiner Geschwister waren Hugo, Emma, Hermann, Hildegard, Adalbert und Otto. Im Frühling 1867, zog die Familie von Kiel nach München, wo Max das klassische Königliche Maximiliansgymnasium besuchte. Schon bald wurde deutlich, dass er ein außergewöhnlich talentierter Mathematiker war. Außerdem erhielt er fast jedes Jahr den Preis aus der “Religionslehre und dem sittlichen Betragen”. Die Lehrer meinten, dass er durch sein artiges und bescheidenes Benehmen einen sehr guten Eindruck mache. Bei seinen Klassenkameraden war er auch sehr beliebt, denn er war stets pflichtbewust, offen und fröhlich. In seinem Zeugnis der zweiten Gymnasialklasse stand: “Mit Recht der Liebling seiner Lehrer und seiner Mitschüler, der Jüngste der Klasse (14 Jahre, 3 Monate) und bei aller Kindlichkeit ein sehr klarer, logischer Kopf. Verspricht etwas Rechtes.” Oskar Miller (damals noch ohne “von”) war einer seiner Klassenkameraden, und war den Lehrern eine echte Plage: “Nicht ohne Talent. Schnell fertig und richtig in seinem Urteil; hört mit einem Ohr mehr als andere auf zwei, aber die personifizierte Unordnung, ohne allen Fleiss und ohne Aufmerksamkeit, den Unterricht stets störend, ein Hemmschuh für die Klasse.” Und während Miller sich gegen die strenge Disziplin aufbäumte, ordnete Max sich mühelos ein. Fast regelmäßig wurde in seinem Zeugnis die “Bravheit” hervorgehoben. Er akzeptierte die Autorität der Schule, wie später die Autorität des Lehrgebäudes der Physik. Ganz gegen seinen Willen führte ihn die Konsequenz seines Denkens um die Wende zum 20. Jahrhundert zur geistigen Revolution.

The German physicist Max Karl Ernst Ludwig Planck, b. Apr. 23, 1858, d. Oct. 3, 1947, developed the concept of the quantum, or fundamental increment of energy, basic to quantum mechanics, and a cornerstone of modern physics. After receiving his Ph.D. from the University of Munich in 1879, Planck taught at the University of Kiel (1885-89) and the University of Berlin (1889-1926). His appointment at the latter institution included the directorship of the Institute of Theoretical Physics that was newly founded for him. Planck began studying black body radiation in 1897 and discovered that at very short wavelengths it did not obey the distribution laws given by Wilhelm Wien . In trying to understand this spectrum using Wien’s laws, Planek ran smack into an "ultraviolet catastrophe". A black body would give off an infinite amount of energy at the ultraviolet end of the spectrum. That was impossible. After working on this problem unsuccessfully for several years. he took a fateful step in late 1900 that he eventually called "an act of desperation." Planck cautiously proposed that, contrary to classical wave theory, matter emits and absorbs radiation in tiny discrete packets or bundles called "quanta" — not continuously, as everyone had assumed. Initially Planck was not comfortable with this explanation and fully expected the idea to be disproved by further research. Instead quantum theory, which gained Planck the Nobel Prize for physics in 1918, was used by

Max Planck was a German physicist whose work was revolutionary to the world of classical physics, his most remarkable contribution to the field being his theses on energy quantisation. Planck's biography is analagously remarkable to his work; the first half of his life was one marked by success, brilliant work which ended up earning Planck world-wide recognition and a Nobel Prize for Physics in 1918. The latter half was marked by tragedy, culminating with the execution of his son Erwin by the Nazi regime in 1945. From Childhood to Quanta Blessed with perfect pitch, Planck was a virtuoso pianist. In 1867, The Planck family moved to Munich and there Planck attended the famous Gymnasium Maximilianeum. When in 1874 he finished school with brilliant marks, Max Planck was seriously considering a career in music. However, by an unknown twist of fate, instead of choosing music he ended up enrolling in the faculty of philosophy, which at that time offered a course comparable to what we would now refer to as physics, with a strong bent towards maths. Planck became a doctor of physics in 1879 and started lecturing one year later - climbing higher yet in the academic ranks. Already by 1892 he was a renowned and respected full professor at Berlin in a field which at that time commanded respect from even the most important of physicists - theoretical physics. However, in spite of this, general academic consensus was that theoretical physics had no practical use and was therefore an intellectually onanistic pursuit. This attitude - along with the structural theories of the entirety of classical physics - collapsed in 1900, when Planck published his account of the (popularly perceived as being irrelevant, but yet lingering) problem of

Físico alemán, premiado con el Premio Nobel l, considerado el creador de la teoría cuántica Planck nació en Kiel el 23 de abril de 1858 y estudió en las universidades de Munich y Berlín . Fue nombrado profesor de física en la Universidad de Kiel en 1885, y desde 1889 hasta 1928 ocupó el mismo cargo en la Universidad de Berlín . En 1900 Planck formuló que la energía se radia en unidades pequeñas separadas denominadas cuantos. Avanzando en el desarrollo de esta teoría, descubrió una constante de naturaleza universal que se conoce como la constante de Planck. La ley de Planck establece que la energía de cada cuanto es igual a la frecuencia de la radiación multiplicada por la constante universal. Sus descubrimientos, sin embargo, no invalidaron la teoría de que la radiación se propagaba por ondas. Los físicos en la actualidad creen que la radiación electromagnética combina las propiedades de las ondas y de las partículas. Los descubrimientos de Planck, que fueron verificados posteriormente por otros científicos, fueron el nacimiento de un campo totalmente nuevo de la física, conocido como mecánica cuántica y proporcionaron los cimientos para la investigación en campos como el de la energía atómica.

Max Karl Ernst Ludwig Planck (23. dubna 1858 – 3. øíjna 1947) Nobelovu cenu získal v roce 1918 za objev elementárních kvant. Nìmecký fyzik Max Karl Ernst Ludwig Planck se narodil v roce 1858 v rodinì profesora obèanského práva. Planck studoval na univerzitì v Mnichovì matematiku a experimentální fyziku, pozdìji na univerzitì v Berlínì u H. L. F. Helmholtze a G. R. Kirchhoffa. V roce 1885 se stal mimoøádným profesorem na univerzitì v Kielu a v roce 1889 se stal vedoucím katedry teoretické fyziky na univerzitì v Berlínì. Max Planck vypracoval práci o podstatì energie, rozpracoval zákony prùbìhu chemických reakcí, disociace plynù a vlastnosti zøedìných roztokù. Od roku 1896 se soustøedil na výzkum tepelného záøení, který byl v roce 1900 korunován jeho životním úspìchem. Planck nazval nejmenší dávku energie vyzaøovanou tìlesem kvantem energie, které je úmìrné frekvenci záøení a konstantì, pozdìji pojmenované Planckovou. Objev byl zpoèátku pøijat s velkou nedùvìrou, nebo znamenal zásadní zmìnu v pøedstavách klasické fyziky o energii a poprvé se objevila myšlenka nespojitosti mezi vyzaøováním a pohlcováním energie. Teprve práce Alberta Einsteina, který na jeho základì vysvìtlil fotoelektrický efekt a dospìl k pojmu svìtelných kvant, a N. Bohra, který vytvoøil nový model atomu, daly zapravdu jeho teorii. Planckova konstanta se stala nedílnou souèástí všech základních vzorcù, které vyjadøují korpuskulární a vlnové vlastnosti mikroobjektù a zákony jejich pohybu.

Editorial Staff quick search Search Physics World Physics World December 2000 Max Planck: the reluctant revolutionary Feature: December 2000 It was 100 years ago when Max Planck published a paper that gave birth to quantum mechanics - or so the story goes. History reveals, however, that Planck did not immediately realize the consequences of his work and became a revolutionary against his will. According to the standard story, which is unfortunately still found in many physics textbooks, quantum theory emerged when it was realized that classical physics predicts an energy distribution for black-body radiation that disagrees violently with that found experimentally. In the late 1890s, so the story continues, the German physicist Wilhelm Wien developed an expression that corresponded reasonably well with experiment - but had no theoretical foundation. When Lord Rayleigh and James Jeans then analysed black-body radiation from the perspective of classical physics, the resulting spectrum differed drastically from both experiment and the Wien law. Faced with this grave anomaly, Max Planck looked for a solution, during the course of which he was forced to introduce the notion of "energy quanta". With the quantum hypothesis, a perfect match between theory and experiment was obtained. Voila! Quantum theory was born.
