pira1000 |
A machine shows the behavior of clocks and measuring rods in two reference frames. |
7F10.20a |
Flow ripple tank |
pira1000 |
Wave propagation upstream and downstream is shown with a flow ripple tank. |
7F10.20b |
Flow ripple tank - twin source |
pira1000 |
Twin source interference in a moving medium is demonstrated with a flow ripple tank and variable phase generator. |

Foam rubber roller |
pira1000 |
|
7F10.26 |
Fitzgerald contraction model |
|
A stick traveling at constant velocity makes a traveling dimple in an elastic sheet. |
7F10.30 |

|
The Edwin F Taylor Spacetime Software is used to generate printouts demonstrating aberration, the Doppler effect, the headlight effect, etc. |
7F10.41 |
Many colored relativity engine |
|
The author's review of a simple program about relativistic space and time that requires no knowledge of physics, algebra, or geometry. |
7F10.50 |
Cylindrical relativity model |
|
A spacetime diagram rolled on a cardboard tube is used to demonstrate the nature of simultaneity and the propagation of light in a rotating coordinate system. |
7F10.55 |
Geometrical appearances |
|
Some examples are illustrated in detail. |
7F10.60 |
