When Olympic athletes perform dazzling feats of athletic prowess, they are using the same principles of physics that gave birth to stars and planets.
Conservation of angular momentum tells us that when a spinning object changes how its matter is distributed, it changes its rate of spin.
Conservation of angular momentum links the formation of planets in star-forming clouds to the beauty of a gymnast's spinning dismount from the uneven bars.
Returning boomerangs are the banana-shaped devices that come back to you when you throw them.
The returning boomerangs are made from lightweight pieces of wood, plastic or similar material and generally measure 1 to 2 feet (30 to 60cm) across. When thrown correctly, a returning boomerang flies in a circular path and returns to its starting point.
