Presentation Transcript

  1. Max Planck Quantum Physicist who was awarded the nobel prize in 1918 for his development of the law of radiation and the quantum theory “I could have easily become a linguist or a historian. What brought me to the exact natural sciences was a mathematics lecture I attended at the university, which I found emotionally satisfying and inspiring” – Max Planck By Jenny Amaral aka Erna

  2. Planck Family History • Max Karl Ernst Ludwig Planck was born in Kiel, Germany on April 23, 1858 • Son of Johann Julius Wilhem Planck and second wife Emma Patzig • His great-grandfather and grandfather were both Theology professors in Göttinger – his uncle a judge • Max was the youngest of six children, two of them from his father’s first marriage

  3. Education • Max graduated high school at an early age of 16 • He was an extremely gifted musician having taken voice lessons along with piano and organ, cello and composed songs and operas, and although he could have easily made this his career, he insteadchose to study physics. • Max chose physics, not for discovery, but simply to understand the fundamentals of physics and thus, began his studies in Munich 1874 • In 1877, he studied in Berlin for a year where he became close friends with famous physicist Hermann von Helmholz, who was, in his teachings, according to Max, never quite prepared, spoke slowly, made endless miscalculations, and overall a bore to his listeners. • Max also met Gustav Kirchhoff, who somewhat opposingly to Hermholz, in his teachings, spoke in prepared lectures that were dry and monotonous. • While there, Planck also met with mathematician Karl Weierstrass. • In October 1878, Planck passed his qualifying exams and in February 1879, gave his dissertation, “Über den zweitenHauptsatzdermechanischenWärmetheorie” (On the second fundamental theorem of the mechanical heat theory) • June 1880, he presented his thesis, “GleichgewichtszuständeisotroperKörper in verschiedenenTemperaturen” (Equilibrium states of isotropic bodies at different temperatures

  4. Academic Career • With the completion of his thesis, Planck became an unpaid private lecturer in Munich and later in April 1885, became an associate professor of theoretical physics at the University of Kiel while continuing his work in heat theory, and by 1892 became a full professor. • In 1907 he refused a positions in Vienna to stay in Berlin. • 1909, eight of his lectures were used by the Ernest Kempton Adams Fund for Physical Research in Theoretical Physics at Columbia University in New York City. • He retired January 10, 1926 in Berlin and was succeeded by Erwin Schrödinger "What Is Life?"

  5. Planck Family • Planck married Marie Merck in March 1887 and had four children: Karl (1888-1916), twins Emma (1889-1919) and Grete (1889-1917), and Erwin (1893-1945) • In the vicinity of Berlin where many professors of Berlin University resided, Planck became good friends with a famous theologian Adolf von Harnack. During this time, Planck’s home became place of social and cultural nature where he had frequent visitors. Those visitors included Albert Einstein - creator of the theory of relativity, and others like Otto Hahn and Lise Meitner. • After several happy years the Planck family was struck with several tragedies. • In October 1909, Marie Planck died from tuberculosis • In March 1911, Planck remarried to Marga von Hoesslin (1882-1948) and fathered his third son, Herrmann. • His oldest son, Karl, was killed in action in Verdun during World War I; Erwin was taken prisioner in 1914by the French; and his two daughters both died givingbirth to their first child, Grete in 1917 and Emma in 1919. • And finally, in 1945, Erwin, his closest son was executedbythe Nazis for his failed attempt to assassinate Adolf Hitler in July 1944.

  6. Quantum Theory • Quantum theory is the nature of matter! • The quantum theory is the work of, not only Max Planck (the originator of quantum theory), but of Werner Heisenberg (who formulated the Uncertainty Principle also known as the principle of indeterminacy – one of the most eminent laws of quantum theory). Other brilliant physicist include Niels Bohr, Erwin Schrödinger, Wolfgang Pauli, and Max Born. • Quantum physics is the leading theory in hopes to understand how our universe was created. Are quantum effects responsible for matter forming discrete entities, instead of spreading out evenly during the birth of the universe? The answer to this question is still being debated today!

  7. Blackbody Radiation • Blackbody radiation or “cavity radiation” is thermal radiation from a black body (an object that absorbs electromagnetic radiation) • Through his research in the observations of the radiation of heated materials, Planck discovered a constant that enabled him to define a new universal set of physical units – that energy is not continuous • He developed a formula which showed that energy is always emitted or absorbed in units, otherwise known as quanta, which further helped to develop his theory in quantum physics that led to this universal constant, now known as Planck’s Constant • Planck’s constant states that energy of each quantum is equal to the frequency of radiation multiplied by the universal constant –E=f*h, where h is 6.63 * 10E-34 Js – which revolutionized physics because it contradicted ideas about the nature of radiation and energy • Law of Radiation: http://classes.atmos.uiuc.edu/100C/Atmos100/day05.html Blackbody Radiation:http://www.youtube.com/watch?v=R2Af_VMTxZY Sixty Symbols – Planck’s constant:http://www.youtube.com/watch?v=Tz2D1aahd5A

  8. Kaiser Wilhelm Society • The Kaiser Wilhelm Society (founded in 1911) was an important scientific institution during World War II that was devoted to different fields in scientific research for the advancement of science • Planck became president of the Kaiser Wilhelm Society in 1930 at the age of 72 until 1937 and after National Socialists came to power was confronted with difficult questions • In an effort to preserve the Kaiser Wilhelm Society, Planck had to make unavoidable compromises while still supporting his colleagues who’s lives were in danger and also managed to re-employ a number of Jewish scientists. • In 1938, Planck resigned in protest of the Nazi regime who shortly after bombed his villa in Berlin • In 1945, he temporarily became president again and in 1946 was the only scientist to attend the Newton anniversary celebrations at the Royal Society in London where he became Honorary President of the Kaiser Wilhelm Society that later became the Max Planck Society founded on February 26, 1948 - but not until after Max Planck’s death on October 4, 1947 (age 89)

  9. Max Planck Institute • The Max Planck Institute is a an independent non-profit society devoted to research for the advancement of science. • There are currently 80 research facilities throughout Germany in the following fields of study listed below… • Biology and Medicine • Chemistry • Physics • Technology • Humanities Max Planck Institute:http://www.mpg.de/english/portal/index.html

  10. Further Work & Publications Planck also worked with albert Einstein (founder of the theory of relativity) making his own contributions to the theory • Planck’s Publications include… • VorlesungenüberThermodynamik (1897) • Entropy and Temperature of Radiant Heat - AnnalenderPhysik, vol. 1. no 4. April, pg. 719-737 (1900) • On the Law of Distribution of Energy in the Normal Spectrum – AnnalenderPhysik, vol. 4, p. 553 ff (1901) “Reality is ... just a very specific, narrow slice of that vast range of what our thoughts try to encompass.”Max Planck, "From the lecture on the law of causality and free will." February 1923
