How was the American Edison's phonograph received in France and Russia?

In 1877, American inventor and entrepreneur Thomas Alva Edison (1847-1931) designed the first household phonograph.

This mechanical device for recording and reproducing sound made a real sensation. Few people believed that a small cylinder with grooves on which a needle slides could reproduce a human voice. During a demonstration of the phonograph at a meeting of the Paris Academy of Sciences, the indignant academician Buyo exclaimed: "We will not allow some ventriloquist to cheat us!"

In Russia, the owner of the "talking mechanical beast" was sentenced to a large fine and three months in prison.

Random interesting fact from the Great Encyclopedia:

What is a cold?

Surely most of you know the joke about the doctor who says to a patient with a cold: "Only if you have pneumonia can I treat you." The common cold is not only one of the most annoying diseases to a person, but also the most mysterious.

More than 90% of Americans get a cold every year, and more than half of them get sick more than once. You probably know the signs of a cold as well as any doctor. Your nose runs, you sneeze a lot, your throat hurts or tickles, and sometimes you get a headache. Later, cough and fever appear.

In adults, colds are rarely serious. But in children, these signs may actually be the first symptoms of a more serious illness, such as measles or diphtheria. That is why children with a cold must be under the supervision of a doctor.

A cold develops in one to three days and has three stages. The first is called "dry", it is not very long. The nose is blocked, the throat begins to tickle, and the eyes are watery. In the second stage, your nose is running. And finally, there is a cough and fever.

Now for the mystery. What is a cold and what causes it? We can describe it as an acute inflammation of the upper respiratory tract. But medicine does not know what causes the common cold!

It is assumed that the disease is caused by a specific virus. But here's what's interesting - it turns out that it is in our throat all the time, but it attacks when our body's resistance drops. The same happens with other bacteria found here. Thus, the cold virus weakens us, while others infect.

The best way to avoid getting a cold is to keep your resistance high. Namely - eating well, resting enough, dressing for the weather and not communicating with people who have already caught a cold.

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. ... >>

No spots left on the sun 07.06.2016

There has not been a single spot on the Sun since June 3, which indicates the beginning of an 11-year cycle of minimum solar activity.

Sunspots are areas where strong magnetic fields enter the solar photosphere. On the solar disk, they look like dark spots. Their temperature is about 1500 kelvins lower than other parts of the Sun's surface.

The eleven-year solar cycle is also called the Schwabe-Wolf cycle. This is a cycle of solar activity, lasting an average of about 11 years. It is distinguished by a rapid (in about 4 years) increase in the number of sunspots and a slower (about 7 years) decrease in their number.

The decline in solar activity entails a decrease in ultraviolet solar radiation, as a result of which the upper layers of the Earth's atmosphere are cooled and destroyed. This will lead to the accumulation of space debris around the planet. The heliosphere will contract and interstellar space will move closer to Earth, causing radiation from deep space to reach our planet with greater intensity.

Of the positive consequences of the decrease in solar activity, one can note the reduction of magnetic storms, which many inhabitants of our planet endure with difficulty.
