1. Little drops of water, little grains of sand, make the mighty ocean and the pleasant land. Little minutes, small though they may be, make the mighty ages of eternity.

2. SPECIAL RELATIVITY

3. REFERENCE FRAMES n Inertial reference frame n Galilean relativity n Accelerated reference frames

4. THE SPEED OF LIGHT n Maxwell’s equations –magnetic and electric field symmetry –accelerating/oscillating charges n Michelson-Morley experiment

5. POSTULATES OF SPECIAL RELATIVITY n The postulate of relativity (reference frames) n The speed of light n The problem of simultaneity

7. RELATIVE MEASUREMENTS n Proper time –single clock at rest

9. RELATIVE MEASUREMENTS n Time dilation –two synchronized clocks

11. RELATIVE MEASUREMENTS n Time dilation –the speed parameter –the Lorentz factor –muon experimental confirmation –the twin paradox

12. RELATIVE MEASUREMENTS n Proper length –no time constraints n Length contraction –Simultaneous position measurements n The Lorentz transformations –displacement –time period

13. Relative Measurements n Velocity n Mass –classical momentum –relativistic momentum and mass n Relativistic kinetic energy

14. Relative Measurements n Total energy, momentum, and kinetic energy relationship n Space-time diagrams –vertical lines –horizontal lines
