Science and Technologies
With the advent of future developments in science and technology, we will assign more and more decision making to machines. At present this is evident in military systems in which electronic sensors maintain the ideal flight characteristics in advanced aircraft. The capacities of computers today exceed five hundred trillion bits of information per second. The complexity of today’s civilization is far too complex for human systems to manage without the assistance of electronic computers.
Computers of today are relatively primitive compared to those that will evolve in the future. Eventually the management of social systems will call for require electronic sensors interconnected with all phases of the social sequences thus eliminating the need for politics. Today modern industrial plants have built in automatic inventory systems, which order materials such as bearings and other mechanical replacements well in advance People became accustomed to live surrounded by the things that make their lives easier and more comfortable.
When we look back at previous centuries and especially at the 20th century we focus on wonderful events: trains, cars, planes making distance shorter; rockets taking people out into space; our homes and offices taken over by successive waves of electronic equipment, including telephones, TVs, faxes, computers, cell phones, Internet facilities, and electronic liberties. Scientific and technological achievements follow so called folklore “science” which lays foundation for genuine science.
For example, common people predicted planes or television in the fairy tales flying carpets or mirrors that show other lands and people. Many fairy tale dreams came true, and the emergence of television proves this. Television has grown up all over the world, enabling nearly every country to share aspects of its culture and society with others. Practically every country in the world now has at least one broadcast television station. It came into being based on the inventions and discoveries of many scientists, engineers, managers.
The idea of television implied in its early stages of development of a combination of optical, mechanical and electronic technologies of capture transmit and display a visual image. All modern television system relies on the electronic technologies, and it is not compatible with the old mechanical type of television. But the knowledge gained from the work on mechanical – dependent systems was crucial in the development of fully electronic television. In early television era televisions were made to be sold from in the United Kingdom, United States, and Russia.
The first person who demonstrated a working television was a famous Scottish engineer John Baird. John Baird, the son of a clergyman, was known for being of poor health for most of his life, but he nonetheless showed early signs of ingenuity. When he was twelve years old, he and some friends built a private telephone system which connected his bedroom to those of his friends across the street. The system worked well, but it had to be closed as one night a storm pulled down the wires that were stretched across by the boys and a man was hurt by the falling wires.
Baird had always been interested in science. He studied at Glasgow University, but the tuition was interrupted by the outbreak of World War One. When the war ended he set himself up in business, but his real dream was creating the television – a dream of many scientist for decades. By 1924 he managed to transmit a flickering image of a Maltese cross across a few feet. On October 2, 1925, Baird transmitted a picture of a human face – the face of a fifteen year old boy. He also gave the first demonstration of both colour and stereoscopic television.
In September 1929, the BBC started experimental transmission with Baird’s equipment. In the 30s his mechanical system was rapidly becoming obsolete as innovative electronic devises came into existence. When BBC committee of inquiry launched in 1935 a side by side trial between the existing television systems, American’s all-electronic system devised by Marconi was found to be the best. The Baird’s system was not chosen, and two years later the Baird’s system was dropped out the use. The history of television is remarkable, and it is tightly connected with the history of human civilization.
All these precious ideas and things are used by people in their everyday life; they are carefully kept in scientific museums such as the National media Museum in England or the Early Television Museum and the Museum of broadcast Communication in the USA. The mission of such museums is to collect, preserve and present technological content of human civilisation as well is to inform, entertain, and educate people. There is no doubt that television made our lives richer, more informative and colourful.
Somehow it made people of the world closer to each other. The society is aware of television and radio as having cultural, creative, and social significance. Both television and radio create communication platforms for common people, media-interested public and the professional community. But there is some anxiety in the society about such topic as violence, tabloid television and the quiz show scandals. The development of technologies moves on: we witness the emergence of such broadcasting technologies as the internet, mobile video and podcasting.
