Dreams create the future
Hello, teachers and students! The title of my following speech is "Dreams Create the Future".
Bell, a professor at Boston University in the United States, suddenly came up with a whim in the process of studying multiplex telegraphy: Can we use electric current to transmit human voices to distant places, so that people who are thousands of miles apart can be close at hand? Woolen cloth? With this dream in mind, Bell began his journey to study telephones. Hard work paid off, and on March 7, 1876, Bell became the patentee of the invention of the telephone. It is precisely because of Bell's phone that the way humans communicate has been refreshed.
Before 1968, the U.S. Department of Defense Advanced Projects Agency had a network construction dream, and the world-famous "ARPAnet" was born. From 1969, when the first host of ARPANET was put into operation, to the end of 1989, ARPANET had been in operation for 20 years. In the past 20 years, network technology has continued to advance, and the number of network users has also continued to expand. Especially in 1987, the number of users skyrocketed. Since 1988, the number of Internet users has doubled every year. In 1995, the Internet's backbone network grew from 6 nodes with a transmission speed of 56,000 baud to 21 nodes, and the data transmission speed also increased to 45 Mbps. At this time, there were about 29,000 websites connected to the Internet in the entire United States, and more than 50,000 websites connected to the Internet worldwide. Today, there are over 100 million websites connected to the Internet around the world. A dream has become the highway of the world's information network.
Thousands of years ago, humans had the dream of flying into the sky. The birth of the first manned spacecraft in 1961 and its successful entry into space made mankind's fantasy of the space world a reality and increased mankind's yearning for space.
The emergence of "frozen human" technology has fulfilled the dream of people suffering from terminal diseases who long to continue to live. Perhaps without terminally ill patients dreaming of survival, scientists would never have thought of “freezing” people. When the level of medical treatment improves in the future, patients will be "thawed" and their diseases will be cured.
Humanity still has many dreams, which may become reality in the near future.
For example, one day, AIDS and cancer will no longer be the "number one killer" of mankind. Human beings will no longer talk about them with disgrace, no longer fear them, but will treat them as easily as they do with diseases such as colds.
For example, one day, humans invented a high-tech product to predict earthquakes, so that the losses caused by natural disasters such as earthquakes to humans can be minimized.
Just think about how many of the dreams of ancient people have become reality today. Electric lights, telephones, televisions, computers, cars, and airplanes are all born out of dreams. With dreams, there is pursuit. With pursuit, there is possibility. When it becomes possible, it becomes a reality. Everything is possible, dreams create the future.
