What invention of Edison is used every day?

The word "Hello" (Hello (English).).

The first written use of hello through the letter "e" occurs in a letter from Thomas Edison to the president of the Pittsburgh Telegraph Company, where the famous inventor proves that the best word for greeting on the phone is "hello", since it is heard "for ten, or even twenty feet".

Edison made his discovery while testing Alexander Graham Bell's prototype telephone. Bell himself preferred a more nautical version: "Ahoy, hoy!", something like "Hey, on deck!".

While working on improvements to the Bell design at the Menlo Park lab, Edison yelled "hello!" all the time. into telephone handsets. Edison's habit was gradually adopted first by all his colleagues, and then by telephone operators. Before Edison's "hello", telephone operators used the phrases "Are you there?", "Who are you?" or "Are you ready to talk?" ("Are you listening?", "Who are you?", or "Are you ready to talk?").

When the word "hello" became the standard, the young ladies-operators were nicknamed "hello girls".

The variant "hullo" in those days was used exclusively to express surprise. Charles Dickens uses the word "hullo" in this sense in the novel Oliver Twist (1839): in the scene where Oliver first meets the Artful Dodger Dawkins, who greets him with the phrase: "Hullo, that covey! What's the row?" (Hey boy! What's the trouble? (English))

"Halloo" ("Atu!", "Hey!") was used when it was necessary to set the dogs or call the ferryman. By the way, this word was also considered one of the favorites in Edison's lexicon. When he first discovered how to record sound (July 18, 1877), the word that the inventor shouted into a typewriter (tape phonograph) was just "Halloo".

"I did an experiment, first on a strip of telegraph paper, and found that the tip wrote the alphabet. I yelled 'Halloo! Halloo!" drove the paper back through the steel tip and heard a faint "Halloo! Halloo!" Then I decided to make a machine that would work neatly and accurately, and I gave instructions to my assistants, telling what I found. "

The earliest officially registered delegate badge bearing the inscription "Hello, that name is..." refers to the first convention of telephone operators held in the city of Niagara Falls in 1880.

In what century did the last execution on the guillotine take place, and Swiss women received the right to vote?

In Europe, in the second half of the 20th century, things were practiced that today are considered absolutely uncivilized. For example, Swiss women received the right to vote only in 1971 (in the local elections of the canton of Appenzell - Innerrhoden and even in 1991). And the last execution on the guillotine took place in France in 1977.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Created a device to simulate odors in computer games 30.10.2022

Scientists at Stockholm University have developed breakthrough technology for computer simulations and games. The device allows you to smell objects or products that are in the simulator or game.

The smell machine - the so-called olfactometer - allows you to smell in virtual reality. A new device that can be printed on 3D printers has been developed by Stockholm University.

This means that the aroma machine can even be used to train wine tasters or perfumers. And for those who, for example, lost their sense of smell after COVID-19 or for other reasons, the new technology will restore the sense of smell through game-based learning. After all, many stop. training is recommended by doctors because it becomes too boring," explained Jonas Olofsson, professor of psychology, head of the research project.

The creators are confident that the new gadget paves the way for new games.
