A second sign at the entry to the toll road will contain a tiny electronic device that will record the driver's identification number that is attached to the car's rear-view mirror. The driver's account will then be billed automatically. If a car does not have an identification card, a camera will photograph the car's license number, and a fine will be sent to the violator by mail. For the past fifty years, the most powerful telescope in the world was the Hale telescope atop Mt. Palomar in rural southern California. Recently, it was replaced as the most powerful one by one installed in Hawaii.
Plans are underway for even more powerful telescopes to be built around the globe.
By the end of the decade, it is estimated that the Hale telescope will be only the seventh most powerful telescope in the world. Here are ideas that experts have suggested. Appliances should have child locks so that children can't turn them on. Drawers in the bathroom and kitchen should have special latches that make it impossible for kids to open. All medicine and kitchen cleaning products should be stored in locked boxes such as fishing tackle boxes.
