  1. Lecture 1. Birth of Quantum Mechanics.Historical Background of QM. Experiments, Theories & Student Presentation • Engel, Ch. 1 • Ratner & Schatz, Ch. 1 • Quantum chemistry, D. A. McQuarrie (1983), Ch. 1 • Molecular quantum mechanics, Atkins & Friedman (4th ed. 2005), Ch. 0 • Introductory quantum mechanics, R. L. Liboff (4th ed, 2004), Ch. 2 Experiments are the only means of knowledge at our disposal. The rest is poetry, imagination. - Max Planck -

Thomson – Discovery of electrons from cathode rays experiment • 1900 – Max Planck – Quantum theory of blackbody radiation • 1905 – Albert Einstein– Quantum theory of photoelectric effect • 1910 – Ernest Rutherford – Scattering experiment with a-particles • 1913 – Niels Bohr – Quantum theory of hydrogen spectra • 1923 – A. H. Compton – Scattering experiment of photons off electrons • 1924 – Wolfgang Pauli – Exclusion principle – Ch. 10 • 1924 – Louis de Broglie – Matter waves • 1925 – Davisson and Germer – Diffraction experiment on wave properties of electrons • 1926 – Erwin Schrodinger – Wave equation – Ch. 2 • 1927 – Werner Heisenberg – Uncertainty principle – Ch. 6 • 1927 – Max Born – Interpretation of wave function – Ch. 3 particle wave

  3. 1900 – Max Planck: Quantum theory of blackbody radiation • What is a blackbody radiation? • Any example in real life? • What is a classical theory for it? • What is “UV catastrophe”? • What is Planck’s assumption? • How did it resolve the dilemma?

(Joseph John) Thomson: Discovery of electrons 1905 – Albert Einstein: Quantum theory of photoelectric effect 1910 – Ernest Rutherford – a-particle scattering experiment 1923 – A. H. Compton: Photon-electron scattering experiment • What is a photoelectric effect? • How was an electron found? • What was the dilemma in the photoelectric effect? • What is Einstein’s assumption? • How did it resolve the dilemma? • Any application of the photoelectric effect in real life? • How did Compton prove Einstein’s theory?
