Atom Smashers or Colliders), ...more
In addition to the traditional topics of mechanical vibrations and waves, coupled oscillators, and electro-magnetic radiation, this course also discusses musical instruments, red sunsets, glories, coronae, rainbows, haloes, X-ray binaries, neutron stars, black holes and big-bang cosmology.
Fundamentals of Physics, II (PHYS 201) After a description of more complicated electric circuits, the basic ideas underlying magnetism are discussed and the relationship between electrical charges and magnetic fields is explored. Magnetism is caused and experienced only by moving charges. The Lorentz force on a charge is described and used to deduce the force on a current carrying wire. The cyclotron and velocity selector are described. ...more
Within a lecture on biological resolution, the synthesis of single enantiomers, and the naming and 3D visualization of omeprazole, Professor Laurence Barron of the University of Glasgow delivers a guest lecture on the subject of how chiral molecules rotate polarized light. Mixing wave functions by coordinated application of light's perpendicular electric and magnetic fields shifts electrons along a helix that can be right- or left-handed, ...more
Professor Saltzman continues his discussion of biomedical imaging technology. Magnetic resonance imaging (MRI) is introduced as an alternate form of imaging, which does not use ionizing radiation yet can provide detailed structure of the body. Functional MRI (fMRI) has a different application from traditional MRI. It can be used to measure oxygen consumption (tissue metabolic rate), and is an important tool in deciphering brain function. T...more
Professor Sylvia Ceyer focuses on the hydrogen atom, beginning with a discussion of electron binding energy to the nucleus. Other topics covered are verification of energy levels for the H atom (including photon emission, transitions between states, and photon emission) as well as the wavefunctions for an H atom. The stations state wavefunction is explained and the three quantum numbers used to describe a wave in 3D – principle quantum ...more
May 19, 2009 - Leonard Susskind lectures on a new class of systems, magnetic systems. He goes on to talk about mean field approximations of molecules in multidimensional lattice systems.
