What was the first human invention to break the sound barrier?

Whip.

The whip was invented in China 7000 years ago, but until the invention of instant photography in 1927, it never occurred to anyone that its “click” was not just a hit of a leather strap on the handle, but also a miniature supersonic clap.

The click accompanies the loop that forms when you swing the whip hard. The loop runs the entire length of the whip and, as the skin tapers towards the tip, accelerates as it moves, reaching speeds more than ten times its original speed. The "click" itself occurs when the loop breaks the sound barrier at about 1194 km/h.

It is officially accepted that the American pilot Chuck Yeager was the first to break the sound barrier on an experimental fighter "Bell X-l" in 1947. In 1948, he also reached a speed of 1540 km / h at an altitude of 21 m - this figure still ranks ninth among manned flights of all times and peoples.

The world record still belongs to the X-15A aircraft - 6389 km / h at an altitude of 31 m, it happened in 200.

The maximum speed that a person has ever traveled is 39 km/h. The Apollo 897 manned spacecraft reached it in 10.

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.
