There are so many wonders of the world. But all of them are different in their nature. In the Ancient times there was Seven Wonders of the World: the Pyramids of Egypt, the Hanging Gardens of Babylon, the Statue of Zeus, the Temple of Artemis, the Mausoleum of Halicarnassus, the Pharos of Alexandria, and the Colossus of Rhodes. They were created by people to glorify beauty and entreat gods or emperors. Nowadays most of the ancient wonders are destroyed but the existing ones still remind us of the man’s power and wisdom.
But wonders of the modern world are different from the ancient ones which were all buildings and statues. In the last centuries there was a time of unprecedented technical and scientific achievements. That’s why the modern wonders are mainly the product of science and technology. And these wonders made our life easier, more efficient and convenient. The achievements of science can be easily seen in the material level modern. These are of course the modern conveniences and appliances. We can’t imagine our life today without telephone, television, fax, cars, planes, computers, space rockets etc. Nowadays modern industry is fulfilled with the help of robots which replaced man in some hard or dangerous labor and run by computers. Robots provide people with all necessities. They have vision systems and work at a very high speed. And today they are used for skilled work like welding, spray painting and assembling components. Although robots have got some disadvantages their main benefits are the quality of work and also that they never get bored with their tasks.
The modern world of high technology could not have come about except for the development of the computer. Different types and sizes of computers find uses throughout society in the storage and handling of data, from secret governmental files to banking transactions to private household accounts. Computers have opened up a new era in manufacturing through the techniques of automation, and they have enhanced modern communication systems. They are essential tools in almost every field of research and applied technology, from constructing models of the universe to producing tomorrow’s weather reports, and their use has in itself opened up new areas of conjecture. Database services and computer networks make available a great variety of information sources. The same advanced techniques also make possible invasions of privacy and of restricted information sources, but computer crime has become one of the many risks that society must face if it would enjoy the benefits of modern technology.
Computer networks have become increasingly important in the development of computer technology. Networks are groups of computers that are interconnected by communications facilities. The public Internet is an example of a global network of computers. Networks enable connected computers to rapidly exchange information and in some cases, to share a workload, so that many computers may cooperate in performing a task. New software and hardware technology is being developed that will accelerate both of these processes.
The achievements of space exploration have surpassed the wildest expectations of men and have overturned so many notions made by reputable scientists who could hardly foresee satellites and long-term stations and international crews working in space for months and astronauts walking in outer space. It is a real wonder, isn’t it?
We have invented many things but we should remember that not all of them are peaceful, because there are such inventions as nuclear weapons, atom bombs, etc. The ecology is also harmed by our inventions. Many species are dying out. Forests are destroyed by acid rains and cut out for farming. Natural resources are being exhausted. So before inventing something we should thing about the consequences first otherwise all of us may disappear one day. But anyway there are so many amazing things have been made in the world today.
