This lecture starts with a thorough review of symmetries and conservation laws. Energy conservation is shown to be a consequence of time translation symmetry and the Hamiltonian is introduced.

Topics: 
  • Recommended books
  • Superluminal neutrinos in the news
  • Review of symmetries and conservation laws
  • Active vs passive transformations
  • Review of momentum and angular momentum conservation and associated symmetries
  • Energy conservation as a consequence of time translation symmetry
  • Hamiltonian and energy conservation
