The 1970s led to great changes that we were not aware of but would contribute to the development of the world.
While some of the emerging inventions revolutionized technology, he was not even aware of what he was doing for that time. Let’s see, what big strides did the world make in the 1970s?
1) Floppy / 1971
Floppy disks are the best solution developed for storing electronic data. Introduced by IBM (International Business Machines) in 1971, the floppy disk was created in 1967 as a result of the work of a group of engineers. It existed before the times of cloud storage, thumb drives and CD. With its patent in 1972, Apple first mass-produced it with the Apple II in 1977.
2) Email / 1971-1978
There is still an ongoing debate for E-mail today, it is not clear who launched it. Ray Tomlinson, a computer programmer at the research and design company now known as BBN Technologies, created a text-based messaging service over the ARPANET network in 1971. He added the “@” symbol to the world of technology to direct the messages. In 1978, VA Shiva Ayyadurai, who was 14 years old, discovered the internal communication system of the University of Medicine and Dentistry, developed “E-mail” and received the copyright in 1982.
3) Cell Phone / 1973
Undoubtedly, the biggest revolution in the technology world started with mobile phones. The first mobile phone was invented in 1973, although Motorola does not have a mobile image. It weighed two and a half pounds, was about a foot in size, and had a talk time of just 30 minutes, with a charge time of 10 hours.
4) Universal Product Code (UPC) / 1974
The retail superhero was first taken as inspiration on the beach of Miami in 1949. Norman Joseph Woodland drew the first sketch of this idea that came to mind in the sand and patented the idea in 1952. It has undergone a great change with the ever-changing designs, but Woodland has been struggling for years, but without success. A team from the National Cash Register managed to read the first product with the new scanners and computers they installed in the Marsh Supermarket in Ohio in 1974, and they made their name in history thanks to Wrigley Juicy Gum.
5) Sticky Notes / 1974
Do you know that these little sticky papers that save our memories and allow us to carry our important notes with us were accidentally produced? Dr. Spencer Silver was working on an adhesive in 1698. Six years later, researcher Arthur Fry tried to use this glue to keep his notes together. The sticky notes, which are still unknown how they came to the present day, emerged by chance and survived to the present day.
6) Rubik’s Cube / 1974
In 1974, while speaking to his students about spatial relations, Erno Rubik prepared the cube to make it more interesting. Saying that he wanted to present it as a work of art in himself, he never wanted it to become a toy. Unable to withstand the system, this cube became child’s play in 1979 and has sold over 350 million copies.
7) Carbonated Drink Lids / 1975
According to an article published in the Journal of Pediatrics in the 1970s, the pull-tab before aluminum beverage cans caused environmental and health debate in the scientific world. Thereupon, engineer Daniel F. Cudzik designed a new mechanism with the “Sta-Tap” used today. He patented the design from most companies in 1975 and 1976.
8) Digital Camera / 1975
It was invented by Kodak engineer Steven Saason in December 1975. He started shooting with a weight of eight kilograms and 0.01 megapixel black and white photos recorded on tape. It took about 23 seconds to take the picture and the picture could only be viewed by connecting it to a television.
9) MRI Machine / 1977
20 for MRI (Magnetic Resonance Imaging) machine. It is one of the greatest medical inventions of the century. Dr. The machine, invented by Raymonda Damadian, founded a company that manufactures MRI scanners in 1977 and completed the first MGR in the human body this year.
10) Sony Walkman / 1979
Walkman was a personal music device that came into our lives by Sony before smartphones. Powered by two batteries, this musical instrument first hit the market in Japan and sold more than 50,000 Walkmans within two months.
