valued all over the world. However, did you know that chocolate cookies were an American invention? The mouth-watering dessert was created by Ruth graves Wakefield in 1930. Transistor
Created in 1947, the American invention of the transistor laid the foundations of modern electronics. The first transistor was built at Bell Labs, having the approximate size of a classic iPod. Without the invention of the transistor, every electronic device would be impossible to create. It can be argued that he is the father of all technologies.
Traffic light
The inventor of the first electric traffic light is considered to be Lester Weir from salt lake city (Utah, USA). In 1912, he developed (but did not patent) a traffic light with two round electric signals (red and green). This is an American invention significantly improving the safety of pedestrians and drivers in the United States and eventually around the world.

kitchen. The microwave oven was invented in 1945 by Percy Spencer, a Maine engineer who worked on a magnetron for radar installations at Raytheon.
Spencer was very fond of sweets: one day he accidentally left a chocolate bar in his pocket and started working with a magnetron. a few minutes later, Spencer felt a melting chocolate in his pocket. That's when he discovered the device's" microwave " potential.
Lasers
The first laser was created by Theodore H. Mayman at the Hughes research laboratory in Malibu, California, in 1960. Today, lasers play an important role in areas such as medicine, astronomy, and engineering
. Personal computer
You probably know companies like IBM and Apple well. Names like Steve jobs and bill gates probably come to mind when you think about the evolution of the personal computer over the decades. However, you should definitely know John Blankenbaker. Blankenbaker is credited with inventing the first Kenback-1 personal computer in his garage in California.

defense programmer ray Tomlinson invented a way to send text messages from person to person via email.
To avoid confusion in the spelling of names, Tomlinson chose a character on the keyboard that never occurs in first and last names as a "separator". And on a computer keyboard, this symbol appeared as an inheritance from the keyboard of typewriters. Back in 1885, the first model of the underwood typewriter (USA) was equipped with a key with the @symbol



.3D печать
3D printing was invented by Charles hull, founder of 3D Systems. In 1986, he patented a device for stereolithography. 3D printing itself can change the way we eat, deal with injuries, create details, colonize space, and even create weapons.

operational in 1993, GPS (Global Positioning System) has become an important tool for national defense strategy, research, and national security. Moreover, it doesn't let you get lost.








"Waffle" sole of sneakers
To create clean shoes that fit perfectly on a variety of surfaces, Nike co-founder bill Bowerman created sneakers with a "waffle" sole. By pouring rubberized liquid into his wife's waffle iron, Bowerman created an American invention. These Nike Waffle sneakers were a huge success, so much so that they are still sold today.

a man's dream of flying a reality. A bunch of failed experiments and other competitors who also started fighting for successful flights led to the fact that the Wright brothers received a patent for a "flying machine"in 1906.

160 years ago, American inventor George B. Simpson received a patent for the first widely used electric furnace. A patent dated September 20, 1859 registered an "electric food apparatus" that can heat and cook food, boil water, and heat a room.

1969:
... at 21:00, a communication session was held between the first two nodes of the ARPANET network, located at a distance of 640 km — at the University of California, Los Angeles (UCLA) and the Stanford research Institute (SRI). Charley Kline was trying to make a remote connection from Los Angeles to a computer at Stanford. His colleague Bill Duvall from Stanford confirmed the successful transmission of each entered character over the phone.
For the first time, only two "LO" characters were sent (originally it was supposed to pass "LOG"), after which the network stopped functioning. LOG should have been the word LOGIN (login command). The system was returned to working condition by 22: 30, and the next attempt was successful. This date can be considered the birthday of the Internet.
Robert Elliot Kahn and Vinton CERF are the inventors of the TCP/IP Protocol. In the media, they are often referred to as the"fathers of the Internet". Winton Surf since 2005 They can also be called the fathers of any computer network, because they invented the fundamental Protocol that underlies data transmission.
