2015-07-15: Can You Trust Your Eyes in Spacetime?

  • 00:02: But before we can graduate to the curves version and general relativity, we need a stronger foundation in spacetime geometry.
  • 01:07: Now, we're not going to do a complete treatment of special relativity or all aspects of flat spacetime geometry.
  • 01:22: Our principle tool for exploring flat spacetime geometry will be something called a spacetime diagram for representing physical events.
