History of the Telephone

Liquid Transmitter...This was the name of the very first telephone ever made. It was founded by Alexander Graham Bell on the March 10, 1876. That very day, Alexander tested his new invention by calling his assistant Thomas Watson: “Mr. Watson, come here, I want to see you.” Unknowingly, Bell launched world's most famously used electronic device.

The newest model of Samsung Phones is the new Samsung Galaxy S6/ Galaxy S6 edge+! It released in August 2015. It comes in 4 different colours: Black Sapphire, Gold Platinum, Silver Titan, and White Pearl. It has a 5.7-inch screen and the body’s made of glass and metal. The S6 Edge Plus ups the amount of RAM to 4GB, up from 3GB in the preceding model. The battery’s been bumped to 3,000mAh, a 400mAh increase. And the handset wirelessly recharges a tad faster — empty to full in 2 hours. You can even connect it to bluetooth and wifi.


It was a vertical metal cone with a piece of parchment stretched over its end (base). On the outside of the parchment, he had glued a cork with a needle in it, pointing into a cup of diluted sulphuric acid.When he spoke into the open end of the cone, the parchment vibrated, so the needle moved. As the needle was wired to a battery, the sound waves converted into an electric signal which travelled in a wire to the receiver.

Though he invented the telephone, he refused to keep one in his study, fearing it would distract him from his scientific work.

Samsung was founded in 1938 by Lee Byung-chul.
