What it Shows

An inverted trash can is launched into the air by an exploding bottle of liquid nitrogen.

What it shows

A telescope (with video output) at the front of the lecture hall is focused on two point light sources at the rear of the hall. Although the light sources are only 1/2 mm apart, they are readily resolved. The Rayleigh limit of resolution can...

What it shows:  Two bodies, rotating about each other, rotate about their common center-of-mass (COM). The COM exhibits uniform motion (or none at all) regardless of what the two bodies are doing.

How it works:  The "bodies" are 4-1/2" diameter acrylic...

[XL | t++ | ***]  inverse square law, luminosity

What it shows:  The intensity of light from a point source decreases as 1/r², where r is the distance from the source.

How it works:  For the point light source, we use a 1500 watt clear light bulb. The...

As demonstrated by two people throwing a volleyball to each other while sitting on rotating platform.

What it shows: 

The Coriolis force is a pseudo force existing in a frame that rotates with constant angular velocity to a reference frame. It acts on a...

A photon (modeled by a bouncing ping-pong ball) is observed from two reference frames and provides the motivation for time dilation.

What it shows:

The Relativity Train is a realization of the famous Einstein gedanken experiments involving traveling trains carrying clocks and meter sticks. The demonstration is used to show how the preservation of the postulated constancy of physical...

Large (20 feet long) Shive wave machine that can clearly show the reflection and transmission of a pulse at the boundary of fast and slow media.

What it shows:

Being so large (20 feet long), transverse traveling waves on this apparatus are easily seen by a...

What it shows:

The Coriolis force is a pseudo force existing in a frame that rotates with constant angular velocity to a reference frame. It acts on a body moving in the rotating frame to deflect its motion sideways. Here the audience sits in the...
