Thousands of villages in the developing world have no telephones. They have no money to build telephone systems. A new kind of technology may help change this situation. I t reduces the cost of building and using telephone systems.
Traditional systems use wires to carry electrical signals from one telephone to another. The wires often cost much more than telephones. The new system is based on radio communication. Each telephone sends and receives signals through the air, but not through the wires. This reduces the cost greatly. The radio telephone gets their power from the sun.
Each is connected to a solar equipment that changes the sun’s energy into electricity. A battery stores the electricity until someone needs to make or receive a call. The telephone turns off by itself if the level of power in the battery falls too low. This prevents damage to the system. Each radio telephone is connected to a computer microprocessor. It rewards how many calls are sent and received. It controls the power supply.
The technology needs more study, but its new use of radio equipment sun power and computers may help start telephone ringing in the other parts of the world.

Artificial(假的) flowers are used for scientific as well as for decorative purposes. They are made from a variety of materials, such as wax and glass, so skillfully that they can scarcely be distinguished from natural flowers. In making such models, painstaking and artistry are called for, as well as thorough knowledge of plant structure. The collection of glass flowers in the Botanical Museum of Harvard University is the most famous in North America and is widely known throughout the scientific world. In all, there are several thousand models in colored glass, the work of two artist-naturalists, Leopold Blaschka and his son Rudolph.?

The intention was to have the collection represent at least one member of each flower family native to the United States. Although it was never completed. It contains more than seven hundred species representing 164 families of flowering plants, a group of fruits showing the effect of fungus diseases, and thousands of flower parts and magnified details. Every detail of these is accurately reproduced in color and structure. The models are kept in locked cases as they are too valuable and fragile for classroom use.?
