What is a perpetual motion machine?

For hundreds of years, people have dreamed of creating a mechanism that, once set in motion, would continue it, performing useful work, while not drawing energy from an external source. However, each of the machines known to us requires an energy source. For example, the wings of windmills rotate using wind energy, while car engines run using the energy released when fuel is burned.

The idea of a perpetual motion machine is that in the course of its work it must produce energy for itself.

In other words, every time, making a full cycle, that is, returning to its original state, it must produce more energy than it consumed. Most people who tried to invent a perpetual motion machine proceeded from some practical considerations. They thought about how wonderful it would be if the mechanism pumped water or ground grain without requiring any energy. Is it possible to create such an engine?

Any scientist will answer you this question in the negative, because the existence of such a mechanism would contradict one of the most important laws of nature: the law of conservation of energy. According to this law, energy in nature is neither created nor destroyed. Energy can change from one form to another, be released, accumulated or dissipated. However, it cannot be created, which means that any mechanism must have a source of energy.

Throughout the history of mankind, thousands of attempts have been made to solve the problem of creating a perpetual motion machine. They began long before the law of conservation of energy was discovered. Even after this happened, there were many reports that such a device had finally been constructed. However, in each such case, the inventor's errors or simple fraud were subsequently discovered.

Who published the first newspaper?

The first newspaper was not like modern ones. It was more like a letter containing news. In the XNUMXth century BC e. in Rome there lived a man who wrote these letters and sent them to people living far from the capital.

Newspapers began to resemble modern ones under Julius Caesar, in 60 BC. e. He forced the government to print a daily bulletin to present it in the Forum. Devoted mainly to government announcements, it was called "Akta Diurna", which in translation means "Events of the Day". In the old days, getting news quickly was important for business.

Business people needed to know what important events had happened. Therefore, the first newspaper, or messenger, was created in the XNUMXth century by the Faggerses, a well-known German family of international bankers. They have also set up a news gathering system to make sure they are reliable. In Venice, at the same time, people paid one gazzetta (small change) to read the news collection issued by the government daily. It was called Recorded News.

The first regular newspaper published in London was called The Informant. This happened in 1663. The very first newspapers to appear could only come out once a week, because both communications and news gathering and production were slow.

The first American newspaper, Public Incidents, began publication in Boston in 1690, but the colony's governor quickly discontinued it. Benjamin Franklin ran the Pennsylvania Gazette from 1729 to 1765. People were so eager to receive news that by the time of the American Revolution, 37 publications were being printed in the colonies. One of the most influential newspapers ever published is The Times in London, which appeared in 1785 under the name of the Daily Universal Register.

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. ... >>
