In this post, the non-exhaustive list of inventions that have revolutionized our daily life.
Nowadays we live in symbiosis with connected electronic devices. Have you ever wondered what the first versions were like? In this post, discover the 10 great inventions that have revolutionized our daily lives.

1 / The invention of the first mobile phone
The Motorola DynaTAC 8000X became the first cell phone released on March 6, 1983. It can hold 30 minutes of talk time, 8 hours of standby time, with an LED display for dialing and redialing one of 30 numbers. from the phone. It sold for $ 3,995 in 1983 and was manufactured by Motorola, Inc.
2 / The first smartphone
IBM Simon which was a product of the merger between IBM and BellSouth is considered the world's first smartphone. It was designed in 1992 but released a year later by BellSouth in 1993.
The smartphone combines the functionality of a mobile phone, a pager, a PDA and a fax machine. It also contained a calendar, an address book, world clock, games and other basic applications that our smartphones contain today.
IBM Simon was also already tactile. It was after him that many other companies created smartphones that were smaller and smaller and more sophisticated than we know today.
3 / The invention of the world wide web
The very first site was info.nxoc01.cern.ch . The latter is running on a CERN NeXT computer which is also the first server in the world at the same time. The world's first web page still exists today and has been online since August 6, 1991. You can find it by going to this link http://info.cern.ch/hypertext/WWW/TheProject.html .
The only people who had web browsing software were Berners-Lee and his colleagues at CERN. Sir Timothy John ou “Tim” or even Tim Berners-Lee (timbl) is a British computer scientist, professor at MIT and the inventor of World Wide Web that we know today in the form of www .
He is now the founder of the foundation World Wide Web (WWW).
While making the first site, physicists at CERN came up with the idea of connecting hypertext (web page) with the Internet and personal computers, thus having a single network to help them share all of the information from the computer stored in the laboratory.
4 / The first multi-task desktop computer
ENIAC (Electronic Numerical Integrator And Computer) was the first general purpose electronic computer. Funded by the US military during World War II, John mauchly et John eckert from the University of Pennsylvania, developed the ENIAC.
It weighed over 27 tons, was approximately in dimension (2,4m × 0,9m × 30m), with 1800 square feet (167 m2), and consumed 150 kW of power. Entrance was possible at from an IBM card reader, and an IBM punch card was used for output. These cards can be used to produce printed output used by an IBM accounting machine, such as the IBM 405.
5 / The invention of the first electronic mail
Raymond Samuel Tomlinson is an American programmer who sent the first email in 1971 to ARPANET network. He received the George R. Stibitz Computer Pioneer Award from the American Museum of Computing in April 2000.
He is also the man who put the sign @ in the email to link the username with the destination address. Before inventing electronic mail, which is now called email, he had the idea of merging an in-machine mail program with another program developed to transfer files between ARPANET computers.
He was born in 1941 in Amsterdam, New York. He received a Bachelor of Science degree, graduating in Electrical Engineering from RPI in 1963. Later he joined the technology company of Bolt, Beranek and Newman, where he helped develop the TENEX operating system including ARPANET Protocol. control network and Telnet implementations.
6 / First commercialized television
If we go for CRT televisions, the credit goes to the radio - german television from the Telefunken company, which was founded in Berlin in 1903. The television games were created by the same company in 1934.
If we remove the cathode ray tubes, then stationary TVs made up of a “neon tube behind a disc” were sold by Baird in the UK in 1928. CRT televisions were then made in France and Great Britain in 1936.
A Scottish engineer, John logie baird, will subsequently invent what will be the first color television and will publicly demonstrate it to the world.
7 / The invention of the first airplane
Successful aircraft invention credit goes to Orville and Wilbur. These are two Americans also known by the nickname of the Wright brothers. They also obtained the record for the first human flight on December 17, 1903.
For the record, the brothers watched the birds and wondered if they can fly? (a lot of people have done it before them anyway).
They noticed that when the birds soar to the sky, the air flowing over the curved surface of their wings creates an upward wind. Birds twist their wings and spin their tails. This observation was of a capital inspiration which allowed them to fly their first plane.
8 / The first microphone
A microphone (commonly known as a microphone) is an instrument that converts sound waves into electrical signals. The author of the invention of the microphone goes to thomas edison.
Initially, two people filed for patents for the carbon microphone, in March and June 1877. Finally, the patent application was approved for Thomas Alva Edison. The loser was Emile berliner.
thomas edison was an American inventor and businessman. He was born in Milan, Ohio on February 11, 1847. Today microphones are used in almost all of our devices such as telephones, tape recorders, karaoke systems, and our computers.
9 / The invention of the first computer mouse
The computer mouse was invented by Douglas Engelbart at the Stanford Research Institute. He invented the first prototype of the mouse in 1963 with the help of his colleague Bill English.
The first mouse was made of wood with wheels that contact the work surface. The famous device has a string attached to the rear part resembling a tail and generally similar to the animal mouse.
The trackball, a related pointing device, was independently invented by Tom Cranston, Fred Longstaff and Kenyon Taylor who were working on the DATAR Royal Canadian Navy project in 1952. This trackball was not used on the mouse invented by Douglas Engelbart. It was later that the ball became an integral part of the smile.
10 / The first super computer
The CDC 6600 Supercomputer is the first supercomputer to use a superscalar multi-core processor. With a computing power of 10 MIPS (ten million instructions per second) and 3,3 MFLOPS in addition / subtraction (a little less in multiplication / division), it was the most powerful computer between 1964 and 1969 , date on which it was overtaken by its successor, the CDC 7600. (extract from wikipedia)
This supercomputer did not exceed the first generation of the intel microprocessor which has a computing power 10 times greater. But of course, it didn't exist at the time.
Today the supercomputer named the K Computer (kei) is the fastest in the world and is created by Fujitsu for the RIKEN Institute for Computer Science Research in Kobe, Japan.
The letter "K" is an abbreviation of the Japanese word "kei", which symbolizes 10 quadrillion. The name is given to it because this computer is capable of 10,51 petaflops. That means it can do a trillion - calculations per second. By comparison, the fastest commercially available Intel processor (the Core i7) is capable of around 109 gigaflops, or around 109 billion calculations per second. This means that KComputer is at least 96000 times faster than your PC.

It should be remembered that I have not listed all the inventions here, we will do it as we go. The list is not exhaustive either, the figures do not represent the order of magnitude of these inventions.
