# Introduction

This is an archive of Quicktime animations used for teaching physics at the ANU.

The Mathematica notebooks should be "loaded to disk".

# Special relativity

## Light Clocks

These animations were produced using Mathematica to demonstrate time
dilation using light clocks.
The notebook can be downloaded.
The animations are explained here.
A stationary light clock:
QT animation (20k).

A moving light clock:
QT animation (330k).

Moving and stationary light clocks:
QT animation (180k).

## Lengths perpendicular to the motion

These were produced using Mathematica to demonstrate the invariance
of lengths perpendicular to an objects motion.
The notebook can be downloaded.
The animations are explained here.
Box and C shape move:
QT animation (60k).

Box moves:
QT animation (20k).

C shape moves:
QT animation (40k).

## Curved space = gravity analogy

This was produced using Mathematica to demonstrate how a curved surface
can simulate a force.
The notebook can be downloaded.
The animations are explained here.
Points moving on great circles of a sphere:
QT animation (50k).
