This shows that in Galilean relativity, two observers moving relative to each other will measure different values for the speed of light.
This demonstrates that two events, simultaneous as observed from one inertial frame of reference are not simultaneous when observed from another inertial frame.
This demonstrates that "moving clocks" advance more slowly than stationary clocks.
This demonstrates how two observers moving relative to each other measure the same speed of light.
This demonstrates how each of two observers, moving relative to each other, sees the other observer's clocks as running slow.
This demonstrates how the coordinates of a set of points in the x-y plane depend on the coordinate system from which they are viewed.
This demonstrates how the coordinates of a set of events in space-time depend on the inertial frame (coordinate system) from which they are viewed.
This is the same as the previous item, but no grid lines are shown.
