Describing the Development of an Invention and Writing Biographies of Scientists
- READ
We use all kinds of devices in our daily life, but we have rarely wondered whether they had the same shape and functions when they were first invented, and if they were as convenient as they are today.
Let us read about the most successful invention of the 20th century:
It is said that the television is an accumulation of other discoveries and inventions.
1831: The era of electronic inventions experimented with electronics for a better life.
1862: Abbe Giovonna invented the Pantelegraph. It transferred an image through wires ,similar to the way telephone wires transfer sound.
1873: Smith and May, two scientists who experimented with selenium. This enabled them to understand that it was possible to transform pictures into signals so as to send them over wires more easily.
1876: George Carey designed a machine that people would use in their homes to view pictures.
1880: Alexander Graham Bell and Thomas Edison invented the photo phone which transferred sound but it could do the same with pictures at a higher quality.
1884: Paul Nipkow demonstrated how we could send multipictures through wires by using a rotating disk to move.
1900: The first “television” was shown at the 1900 World Fair in Paris.
1907: Scientists used “cathode rays” and “a vacuum tube” to work the television.
1924: John Baird was able to develop a way to capture objects in motion.
1925: the first long distance television test was done between Washington D.C and New YorK.
1950s: Colour TV was released to the public in 1955.
1997: Panasonic engineers developed and released the flat screen TV.
2009: Digital television viewing became mandatory in the USA.
When we write about the development of an invention through time, we always start with a brief introduction in which we contrast the present state of the invention with the past.
Then, we enumerate chronologically the main dates that highlight the evolution and improvement of the invention.
Last piece of advice: use pictures and make your sentences simple, short and precise.

- He was born on March 3rd,1847. (eighteen, forty-seven)
- He died in Canada on August 2nd,1922.
