Mind Blowing Inventions That Changed The World

We are here to talking about the average inventions that changed the world and it's technology. And make the world developed because of this scientists who invent this things. 

The Wheel

The wheel was invented in the 4th millennium BC in lower Mesopotamia(modern day Iraq), where the summarian people inserted rotating axis into solid discs of wood. It was only in 2000 BC that the discs began to be hollowed out to make a lighter wheel. This Innovation led to major advances in two main areas.

The Wheel was invented in an age known as the Chalcolithic age. It's also known as Eneolithic or Aeneolithic age. It was the time period during which the first ever metal was used by man. In the modern age, 

it is used to make brass and bronze alloys.

The Compass   

The Compass was invented in China during the Han Dynasty between the 2nd Century BC and 1st Century AD. The magnetic Compass was not, at first, used for navigation, but for geomancy and fortune telling by the Chinese.

Historians think China may have been the first Civilization to develop a Magnetic compass that could be used for navigation. Chinese Scientists may have developed navigational compass as early as the 11th or 12th Century.

The Telephone 

Telephone was invented by Alexander Graham Bell. The first telephone was invented on 7 March 1876, bell was granted US patent 174465A, for a method of transmitting speech by telegraphy.

In the 1870s, Elisha grey and alexander graham bell Independently designed telephone could transmit speech electrically.

Printing press

German goldsmith Johannas Gutenberg is credited to invented Printing press in 1436, although he was far from the first to automate the book printing process. Woodblock printing in china dates back to the 9th century and Korean bookmakers were printing with moveable metal type a century before Gutenberg.

Johannas Gutenberg was a political exile from Mainz, Germany when he began experimenting with printing in Strasbourg, France in 1440. He returned to Mainz several years and by 1450, has a printing machine perfected and ready to use commercially : The Gutenberg Press.

Nails 

It's Unknown exactly when nails were first invented, but archaeological evidence shows nails were used in Ancient Egypt around 3,400 B.C. Since then, little has changed regarding their designs. 

The cut-nail process was patented in America by jacob perkins in 1795 in England by Joseph Dyer, who set up machinery in Birmingham. The process was designed to cut nails from sheets of iron, while making sure that the fibres of the iron ran down the nails. 

Light Bulb

In 1802, Humphry Davy Invented the first electric light bulb. He experimented with Electricity and invented an electric battery. When he connected wires to his battery and a piece of carbon, the carbon glowed producing light. 

US inventor Thomas A. Edison is often credited with creating the solution on 1879. The carbon filament light bulb. Yet the British chemist Warren de La Rue had solved the scientific challenges nearly 40 years earlier.

Internet

The first workable prototype of the internet came in the late 1960 with the creation of ARPANET, The Advanced Research Projects Agency Networks. Originally funded by the U.S. Department of defense, ARPANET used packet switching to allow multiple computers to communicate on a single network.

Computer Scientists Vinton Cerf and Bob Kahn are credited with inventing the internet communication protocols we use today and system referred to as the internet.
