The basic umbrella was invented over four thousand years ago. We have seen evidence of umbrellas in the ancient art and artifacts of Egypt, Assyria, Greece, and China. These ancient umbrellas or parasols, were first designed to provide shade from the sun. The Chinese were the first to waterproof their umbrellas for use as rain protection.

Soon after telescopes were invented, people started to fasten two of the long tubes together to make binoculars (from the Latin "two eyes"). Around 1900, a German physicist named Ernst Abbe made a pair of binoculars using prisms. The triangular prisms each reflected the incoming light twice. This meant it was possible to make a shorter instrument. The two prisms also flipped the image upright.

Camera The history of the camera - Camera Obscura, photography, the significant processes of photography, and who invented the Polaroid and photographic film. In 1818, Baron von Drais introduced a machine to the public in Paris. It had two in-line wheels connected by a wooden frame. The rider sat astride and pushed it along with his feet, while steering the front wheel.
