Necessity is the mother of invention, as they say, and she has created some fairly unusual children.

Inventors and Inventions I — Animal Tracking Satellites let scientists follow elephants, whales, and manatees. Baby Stretcher When an infant is injured, this child-size stretcher provides more protection. Biodegradable Golf Tee Take your swing, then leave the tee where it stands. Nature will do the rest. Boomerang From aboriginal weapon to child's toy, learn about the forces that bring boomerangs back. Velcro The idea for this handy fastener came from a walk in a field thick with burrs.

Inventors and Inventions II — Explore some of the discoveries that opened the heavens to humanity. Leonardo da Vinci Artist and inventor Leonardo da Vinci created on paper, at least the first helicopter. Galileo's Telescope This Renaissance man risked all to discover the secrets of the spheres with his telescope.
