Презентация на тему The Greatest inventors and invetentions John Logie Baird invented television

Introduction
Wonderful inventions have been made in science and

technology recently. This advances are changing the lifestyle of millions of people all over the world. By the end of the 20th century lots of inventions have been appeared. Some of them have become so commonplace that it is difficult to imagine them things to make our life more comfortable. Almost every day a new technique or product appears in the world.

It had been realized for some time that light could be converted into electrical impulses, making it possible to transmit such impulses over a distance and then reconvert them into light.

into existence: mechanical television and electronic television.

television held great potential but were not converted into reality. Finally, in 1927, Philo Taylor Farnsworth was able to invent a working model of electronic television that was based on Swinton’s ideas.

an American inventor called Charles Jenkins used the disk

idea of Nipkow to invent the first ever practical mechanical television system. By 1931, his Radiovisor Model 100 was being sold in a complete kit as a mechanical television.

in 1888. His father was a graduate in Arts

and Divinity of Glasgow University and had moved to Hel­ensburgh, a little town on the Firth of Clyde, to become minister in a small parish church. The boy respected his father and adorned his mother.

Logie Baird pioneered early television with the mechanical scanning

system he developed from 1923 to the late 1930s. He is remembered today as an inventor (178 patents) with considerable insight, who was in many ways ahead of his time. Among his pioneering ideas were early versions of color television, the video disc, large screen television, stereo television, televised sports, and pay television by closed circuit.

as the inventor of mechanical television, radar and fiber

optics. Successfully tested in a laboratory in late 1925 and unveiled with much fanfare in London in early 1926, mechanical television technology was quickly usurped by electronic television, the basis of modern video technology.

Baird
Baird died in his sleep on the 14th June

1946, before he could complete his work. There was not any place in Westminster Abbey for this genius, no lavish praise from the BBC, no honours from his country. He was buried in the little churchyard in Helensburgh, the place of his birth.

Conclusion

That`s why my favourite TV programme is «Who wants

to be a millionaire?» The programme is now hosted by Dmitry Dibrov. I think it is the perfect way to be in the known of everything. I find this programme clever and informative.

In short, television does have its good points. Many of the programme that broadcast are educational and can help with schoolwork.
