Who Invented Television

by admin on August 24, 2009

The invention of television is a highly debated topic. There are several inventors who have claimed credit for the invention. Guglielmo Marconi first created wireless telegraphy in 1897, and after this invention, many inventors began to experiment with sending images and sound wirelessly as well.

Edwin Belin, and Englishman who was living in France was the first one to transmit photographs wirelessly. On the 2nd of December, 1922, Belin showed his invention off. Belin’s invention was a mechanical device that took flashes of light which produced sound waves. These sound waves could be received in a different location and then turned back into flashes of light on a mirror. This was the precursor to television. However, it wasn’t until the invention of electronic scanning of imagery, where images are broken up into tiny bits of light and then sent by radio waves, that modern television came about.

The invention of the modern television comes down to two inventors who were working on the same invention at the same time. Philo Taylor Farnsworth and Vladimir Kosma Zworykin both competed to invent the first TV. In 1923, Zworykin patented the iconoscope, which was an electronic image scanner, and the primitive form of a television camera. However it was Farnsworth that was first able to successfully demonstrate the technology in 1927, using a scanning tube of his design which he then patented. Thus Farnsworth became credited for invented the modern television, although he essentially improved upon Zworykin’s design. Zworykin, who began to work for RCA, would later try to claim rights for the essence of television, but in the trial to decide the true inventor, Farnsworth’s high school science teacher was brought to Washington in order to testify that Farnsworth had first came up with his idea of the television scanning tube as a 14 year old. RCA was forced to pay Farnsworth royalties in 1939.

Who Invented Glass

by admin on August 13, 2009

Glass is a clear, solid material that is usually translucent and can come in a variety of colors. Glass has been used all over, from windows in churches, to drinking glasses.

Glass originated in around 3000 B.C. during the Bronze Age. The Egyptians were the first to use glass, with artifacts showing glass being used as ingots and beads.

Modern glass came about during the Ptolemaic period which dates from about 305 B.C. Artistans began to create “mosaic glass” which were bits of arranged colored glass to create decorative patterns. Glass would later be moulded into different shapes using glassblowing, a technique which first appeared in 100 B.C. by Syrian glassmakers.

Rhe first clear glass appeared during the 15th century in Venicecalled, and was called cristallo. It would be heavily exported all around the world. Crystal was invented 175 years later, after glassmaker George Ravenscroft added lead oxide to glass, creating lead crystal glass.

In 1902, sheet glass would be invented, which allowed for the mass production of windows. Two years later, the “glass shaping machine” was also invented, which allows us to shape glass into virtually anything, including jars, bottles, etc.
