In 1905, Albert Einstein published five papers that changed the course of physics and the modern world. In this episode, we look at the first three of those works including his paper on the photoelectric effect, his derivation of Avogardo's number and his analysis of Brownian motion that more or less proved the existence of atoms.
In this last episode on Richard Feynman, we cover his work in condensed matter physics on superfluidity and superconductivity, the development of V-A meson theory and parton theory. We also discuss his work with the presidential commission investigation the Challenger explosion.
In this continuation of our biography of the life and scientific work of Richard Feynman, we look at the work for which he would win his Nobel prize. Beginning with his move to Cornell after the end of the Manhattan Project, we cover his full development of the path integral formulation of quantum mechanics, it's application to renormalization of quantum electrodynamics and the development of his Feynman Diagram. We also consider the contributions of Julian Schwinger and Freeman Dyson.
A biographical sketch of Wolfgang Pauli and his contributions to quantum physics.
A few quotes by or about Pauli:
In this episode, we begin with the wave mechanics approach of Erwin Schrodinger and work through the Fifth Solvay Conference held in October of 1927. We discuss the crisis that arose in the atomic physics community and the debate between the matrix mechanics of Werner Heisenberg and the wave mechanics of Schrodinger, concluding with the development of the Uncertainty Principle and the Copenhagen Interpretation.
In this episode we address the crisis in atomic physics, the work of Louis de Broglie and the matrix mechanics of Werner Heisenberg. Also discussed are Wolfgang Pauli, John Slater, Hans Kramers and Max Born.
In this episode, we discuss the contributions of Gilbert Newton Lewis, Irving Langmuir and Arnold Sommerfeld and push the Bohr Model of the Atom to the breaking point.
A discussion of the life and influence of Niels Bohr.
In this podcast, we look at the development of a theoretical model of electron behavior for Rutherford's nuclear model of the atom by Niels Bohr. We begin with a brief introduction to light and spectra before considering the groundbreaking work of Max Planck and Albert Einstein and then finally to Bohr's radical solution to electron behavior around a nucleus. This is the first episode in the series where things get really strange.
Also discussed are the three spectral laws of Robert Bunsen and Gustav Kirchoff, the ultraviolet catastrophe and the photoelectric effect.
A look at the life of Ernest Rutherford after the Great War, including the first transmutation of an element, the discovery of the neutron and the splitting of the atom. Others scientists in the podcast include Ernst Marsden, James Chadwick, Pyotr Kapitsa, John Cockcroft and Ernest Watson.
A biographical sketch of the life of Ernest Rutherford from his birth in New Zealand to the outbreak of the Great War.
In this episode, we develop the atomic models of Hantaro Nagaoka (Saturnian Model), J.J. Thomson (Plum Pudding Model) and Ernest Rutherford (Nuclear Model). We also consider the theoretical work of Perrin and Anton van den Broek along with the experimental contributions for Hans Geiger, Ernest Marsden, Charles Barkla and Henry Moseley.
In this supplemental episode we cover the life of Marie Curie from her childhood in Warsaw to the discovery of polonium and radium to the founding of the Radium Institute.
In this episode, the work of first Wilhelm Conrad Röntgen (the discovery of X-Rays) and Henri Becquerel (the discovery of radioactivity) is discussed followed by the discoveries of Pierre Curie, Marie Curie and Ernest Rutherford.
This episode begins a multipart series discussing the discoveries at the turn of the 20th century that led to the downfall of Dalton's atom and a new understanding of the nature of matter.
This episode focuses on the work of JJ Thomson at the Cavendish laboratory that led to the discovery of the electron. Others mentioned in the episode include Henry Cavendish, James Clerk Maxwell, William John Strutt (Lord Rayleigh), William Watson, Heinrich Geissler, William Crookes and Robert Millikan.
In this episode, developments in electrochemistry by Jons Jacob Berzelius, Humphry Davy, Michael Faraday, Svante Arrhenius, Wilhelm Oswald, Jacobus Henricus van 't Hoff and Alfred Werner are discussed.
A discussion of the development of the periodic table beginning with Prout's protyle and ending with Mendeleev. Much of the material for this episode has been developed from Eric Scerri's, "The Periodic Table, Its Story and Its Significance." Persons discussed include William Prout, Johann Wolfgang Döbereiner, Leopold Glemin, Max Joseph Pettenkofer, Ernst Lenssen, Alexander Emile Beguyer De Chancourtois, John Newlands, William Odling, Gustavus Hinrichs, Lothar Meyer and Dmitri Mendeleev.
This episode discusses the life and contributions of John Dalton with particular focus on his development of the Billiard Ball model of the atom.
Reflections on chemistry by Michel Eugene Chevreul on the occasion of his 100th birthday.
Color Wheel developed by Cheveul.
From Bruno to Boscovich, the podcast suveys the development of the intellectual and experimental lanscape of Renaissance Europe as it moves closer to answering the question of the nature of matter. Other scientists discussed include Pierre Gassendi, Galileo, Rene Descartes, Francis Bacon, Robert Boyle and Isaac Newton
