  1. 8.14: Jr. Lab. IIWhat’s new, different and why should you take it?

  2. Poisson statistics (Poisson 1835, Rutherford, Bateman, Geiger 1910) Electromagnetic pulses (Kelvin 1855, Heaviside 1885) Photoelectric effect (Hertz, 1887, Lenard 1902, Einstein 1905) Optical spectroscopy (Balmer 1885) Alpha decay (Becquerel 1896) Relativistic dynamics (Einstein 1905) Rutherford scattering (with Geiger & Marsden 1909 Franck-Hertz (1914) 8.13: Early 20th century physics

  3. Compton scattering (1923) Johnson (Johnson & Nyquist 1928) and shot noise (Schottky 1918) Nuclear Magnetic Resonance (Rabi 1938, Bloch & Purcell 1952) Cosmic-ray muons (Anderson & Neddermeyer 1936) 21 cm radio astrophysics (Jansky and Reber 1936) Neutron physics (Wollan & Shull 1945) 8.13: Early 20th century physics

  4. Zeeman effect Splitting of spectral lines in external magnetic field With Lorentz, 1896 Superconductivity For T<TC, R0! Onnes, 1911 Optical pumping Population inversion  laser! Kastler & Brossel, 1951 Mössbauer spectroscopy Energy levels of nucleus! Mössbauer 1957 Doppler-free laser spectroscopy Hyperfine structure! Laser >1960, Lamb, Schalow Quantum Information Processing Feynman 1985, Gershenfeld & Chuang, Cory et al. 1997) 8.14: second half of 20th century

  5. Should I take 8.14?Or should I do a UROP and publish a paper?

  6. Do both, if you can … with some consequences clipartguide.com Eugeniy @ 40m Lab

  7. Why? • In 8.14 you learn a broad range of physics and laboratory techniques • Precision spectroscopy • Cryogenics • Laser interferometry • More sophisticated data analysis techniques • Observe firsthand the physics of 8.06, 8.321, 8.08, 8.371, 8.421 • While doing a UROP you learn about one (narrow sub-) field of physics in greater depth Junior Lab builds a broad set of laboratory and analytical skills

  8. Closing remarks You have been a great section Every single one of you has grown tremendously (watch your intro oral videos and compare them to the final orals, e.g.) Good luck with finals See you in 8.14
