People have invented many useful devices. One of the most interesting and widely-used inventions is the telephone.
The modern phone that we use today is the result of work of many people. The first person to have patented the telephone in 1876 was Alexander Graham Bell. He is credited as the inventor of this practical device. Other scientists who also worked on telephone invention were Elisha Gray, Antonio Meucci, Thomas Edison and some others. The 20th century was the era of phone development and modernization. Rotary telephones were replaced by touch-tone dials and other sophisticated features.
Modern phones are presented mostly by mobiles, which support IP telephony and wi-fi. It is almost impossible to find a person nowadays who doesn’t have a personal mobile phone. These phones have become highly popular over the last years. They are rather compact, handy and easy to carry around. Mobile phones allow us to make instant calls, send text messages, listen to music, play games, take photos, check an e-mail and else. Thus, they have replaced not only landlines but also personal computers, MP3-players and cameras.
However, there are many people in the world who are against mobiles phones. Doctors claim that this device has a bad effect on people’s health. It can damage our eyesight and immune system. The signals that are sent from mobiles can be harmful. Some people also believe that phones prevent live communication. And, it is true. With the appearance of mobile phones and computers people meet up with friends less often.
In my opinion, telephone is a very useful and important device. We simply can’t live without it in the modern world, even though it is not safe for health. The only solution is to try to use it less in everyday life.
