How does electronic paper work? http://www.kidsworldfun.com/images/e-paper.jpg Electronic paper, also known as e-paper or Electronic Paper Display (EPD) is a display which imitates the appearance of ordinary paper. Electronic paper is portable and reusable – it can be refreshed (electronically) and written upon millions of times. Many different technologies are used for making e-paper. The most commonly used e-paper consists of millions of tiny plastic capsules which are sandwiched between two sheets of flexible plastic. Each capsule, which is as narrow as a human hair, contains several positively charged white beads and negatively charged black beads floating in a clear fluid. When an electric voltage is applied to each of the capsules through the circuitry embedded underneath, the beads, due to their unlike charges, get separated and move to the opposite faces of the capsule. When white beads are on top, the upper face of the capsule appears white, thus making the display appear white at the point where the capsule is located. Similarly, when black beads are on top, the display appears black at the point. Thus, each capsule functions as a separate pixel allowing the black text or picture to be visible on the display. |
Who invented the yo-yo?
http://www.kidsworldfun.com/images/yo-yo.jpg The yo-yo is an ancient toy, with the oldest surviving model dating back to 500BC. Ancient Greaks made the toy from wood, metal and terracotta. In the Philippines, hunters used yo-yos as retractable weapons – rocks were attached to 6.09m long thick ropes which were hurled at wild animals. The yo-yo derives its name from a native Filipino word meaning ‘come back’. In the 18th and 19th century, the simple yet dynamic toy that worked on the principles of physics became very popular in Europe and was known by various names like bandelore, quiz and L’emigrette. In 1928, a Filipino American named Pedro Flores opened a small toy factory in California, USA, becoming the first person I the world to mass-produce yo-yos. The yo-yos became such a rage that a businessman, Donald Duncan bought over Flores’ company. Doncan’s factory manufactured 3600 yo-yos in an hour, earning the town of Luck in Wisconsin, the epithet of ‘Yo-Yo Capital of the World’! The yo-yo has undergone various innovations to make it spin faster and longer. Today, yo-yo competitions are held all over the world. |
What are barnacles?
http://www.kidsworldfun.com/images/barnacles.jpg If you have been to the sea coast you might have seen barnacles. Many a barefoot runner on the seashore finds his foot lacerated when he accidentally steps on a barnacle. Barnacles, lie crabs and lobsters, their distant cousins, are members of the phylum Arthropoda, the largest and most diverse group of animals on earth. Barnacles alone account for more than 1200 known species. Some are fresh water inhabitants while a few live as parasites on other animals. Some of them, like the acorn barnacle, grow directly on a hard rocky surface while others like the goose barnacle attach to it by means of a stalk. Life as a barnacle is not easy. A marine barnacle living in the inter-tidal area is alternately lashed by fierce waves one moment and roasted by the sun the next. When exposed to the sun, barnacles stop all activities and concentrate on keeping themselves moist. They live in shells made of calcium carbonate, (the substance found in marble and chalk) and rely on the tides to bring their food. Barnacles have six pairs of legs that form a type of net to filter plankton which is their food. |
