  1. Physics: the basic subfields • The fundamental physical laws • Classical mechanics(PHY 110, 220, 320, 380.03) • Electromagnetism(PHY 111,112, 240, 340, 330) • Thermodynamics(PHY 111, 325) • Quantum physics(PHY 112, 284, 384, 355, 287) • (including atoms, molecules, solids, nuclei, fundamental particles) • Statistical mechanics (PHY 111, 325, 380.03) • General Relativity (PHY 207, 287: Indep. study!)

  2. Physics: What’s that field? • Determine the motion of spacecraft in the solar system for NASA missions • mechanics, general relativity • Determine the motion of atoms in a solid as it is heated • quantum physics, mechanics, statistical mechanics • Explain how lightning is generated in a thunderstorm • electromagnetism, quantum mechanics, statistical mechanics

  3. Physics: What’s that field? 2 • Design a new high intensity blue laser • quantum physics, electromagnetism • Try to reduce the production of waste heat in a diesel engine • thermodynamics, statistical mechanics • Derive the chemical law of 'detailed balance' from the behavior of atoms and molecules • statistical mechanics

  4. Physics: What’s that field? 3 • Measure the bending of light around the planet Jupiter due to its gravitational field • general relativity, electromagnetism • Figure out how a particle-antiparticle pair is created out of the vacuum in a particle accelerator • quantum physics, statistical mechanics, E&M • Determine how far into the future the weather can be predicted • statistical mechanics, mechanics • Understand the universe: all subfields

  5. Methodologies of Physics • Experimental Physics • Observe nature(e.g. astro, geophysics) • ‘Prod’ Nature into revealing secrets(laboratory experiments) • Theoretical Physics • Build theoretical models of reality • Solve models mathematically • Computational Physics • Build computational models of reality • Solve models via computer simulation
