Per Wikipedia, Paul Ehrenfest (1880 – 1933) Was An Austrian Theoretical Physicist Who Made Major Contributions To Statistical Mechanics And Its Relation To Quantum Mechanics. He Majored In Chemistry At The Vienna Institute Of Technology, But Took Courses At The University Of Vienna, In Particular From Ludwig Boltzmann On His Kinetic Theory Of Thermodynamics. These Lectures Had A Profound Influence. In 1903, He Met Dutch Physicist Hendrik Lorentz During A Short Visit To Leiden, Netherlands. He Wrote His Dissertation On Die Bewegung Starrer Körper In Flüssigkeiten Und Die Mechanik Von Hertz (The Motion Of Rigid Bodies In Fluids And The Mechanics Of Hertz) And Obtained His Ph.D. On 23 June 1904 In Vienna, Where He Stayed From 1904 To 1905. Because He Was Unwilling To Declare Belief In Any Religious Denomination, He Could Not Apply For A Professorship And Therefore Had No Prospect Of Securing A Permanent Position.[6] In 1912, Ehrenfest Toured German-Speaking Universities In The Hope Of A Position. He Visited Berlin, Where He Saw Max Planck; Leipzig, Where He Met His Old Friend German Mathematician Gustav Herglotz; Munich, Where He Met Theoretical Physicist Arnold Sommerfeld; Zürich; And Vienna. In Prague He Met Albert Einstein For The First Time, And They Remained Close Friends Thereafter. Einstein Recommended That Ehrenfest Succeed Him In His Position In Prague, But The Plan Failed Since Ehrenfest Declared Himself An Atheist.[7][8] Sommerfeld Offered Him A Position In Munich, But Ehrenfest Received A Better Offer; At The Same Time There Was An Unexpected Turn Of Events: H. A. Lorentz Resigned His Position At The University Of Leiden, And On His Advice, Ehrenfest Was Appointed As His Successor. In October 1912, Ehrenfest Arrived In Leiden. To Stimulate Interaction And Exchange Among Physics Students, Ehrenfest Organized A Discussion Group And A Study Association Called De Leidsche Flesch ("The Leyden Jar"). He Maintained Close Contact With Prominent Physicists In The Country And Abroad, And Invited Them To Visit Leiden And Give Presentations In His Lecture Series. Among His Students Were Johannes Burgers, Hendrik Kramers, Dirk Coster, George Uhlenbeck And Samuel Goudsmit, Who Became Famous For Jointly Proposing The Concept Of Electron Spin, Jan Tinbergen, Arend Rutgers, Hendrik Casimir, Gerhard Dieke, Dirk Struik, And Gerard Kuiper. His Assistants Included Yuri Krutkov, Viktor Trkal, Adriaan Fokker, Paul Epstein, And Gregory Breit. Other Young Foreign Scientists Who Spent Extended Periods In His Laboratory Included Gunnar Nordström, Enrico Fermi, Igor Tamm, Oskar Klein, J. Robert Oppenheimer, Walter Elsasser, Ralph Kronig, Werner Heisenberg, Paul Dirac, And David Dennison.Ehrenfest's Most Important Contribution From 1912 To 1933 Is The Theory Of Adiabatic Invariants, A Concept Derived From Classical Mechanics That Can Serve To Refine Certain Methods Of Niels Bohr's Model Of The Atom, And Also Creates An Association Between Atomic Mechanics And Statistical Mechanics. He Made Major Contributions To Quantum Physics, Including The Theory Of Phase Transitions And The Ehrenfest Theorem, Which States That Expectation Values Of A Quantum System Conform To Classical Mechanics. His Name Is Also Given To The Ehrenfest Paradox, An Apparent Paradox Of Relativity, To The Ehrenfest Model, And To Ehrenfest Time, The Time Characterizing The Difference Of Quantum Dynamics For Observables From Classical Dynamics. Ehrenfest Was Also Interested In Developing Mathematical Theories For Economics. His Student Jan Tinbergen Received A Nobel Prize In Economics.…
