The subject of this month's feature column from the American Mathematical Society Online is the solution to the "Three Body Problem" of Newtonian mechanics. The problem deals with three orbiting bodies of equal mass and...

This webpage from Exploratorium provides an activity that demonstrates the Bernoulli principle with readily available materials. In this activity a table tennis ball is levitated in a stream of air from a vacuum...

This activity from the provides a demonstration of the relationship between an object’s center of gravity and its angular momentum. One attempts to balance a stick with a piece of clay stuck to it in various locations. ...

This Exploratorium site provides a demonstration using an ordinary bicycle wheel and rotating stool to show how gyroscopes behave. A person sitting on the stool is turned due to a change in the direction of the axis of...

This activity from the Exploratorium provides a technique for determining the center of gravity of a long, thin object using only one’s hands. A yard stick, with a piece of clay to displace its center of mass, is placed...
