Who was the first astronaut?

The idea of interplanetary travel arose a very long time ago, but only in the last fifty years has cosmonautics become a reality. Back in 1903, the Russian discoverer K. E. Tsiolkovsky suggested using rockets for space exploration, since rockets are propelled by jet engines and do not depend on the atmosphere. He also suggested using liquid-fueled rockets, since solid-fueled rockets had much less thrust and the process of fuel combustion in them was much more difficult to follow.

In 1926, the American R. H. Goddard launched the first liquid-fuel rocket of the modern type. Active research in this area was also carried out in Germany, as a result of which liquid-fuel rockets V-2 appeared, with the help of which rocket strikes were carried out against England during World War II.

After the war, a serious development of space technology unfolded in the Soviet Union and the United States. The first artificial earth satellite was launched by the Soviet Union in 1957. In 1961, the USSR amazed the world by launching into space a rocket with the first man on board - Yuri Gagarin, who during his space flight made one revolution around the Earth.

Random interesting fact from the Great Encyclopedia:

Which country has a comprehensive genealogical database dating back to the 18th century?

Every citizen of Iceland has access to the Islendingabok website, a genealogical database containing information about family ties of all Icelanders since the 18th century. The task of compiling such a database could be solved thanks to the not very large population of the state (just over 300 thousand) and the fact that Iceland throughout its history was weakly influenced by both emigration and immigration. Many young people use this site to check if their new lover is a cousin or cousin to rule out the possibility of incest. Another popular use of the site is to check the degree of your relationship with famous personalities. For example, every Icelander can find out how many generations he is related to Björk.

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 ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

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. ... >>

Artificial eye the size of a fly 23.05.2013

Scientists and engineers at the Polytechnic School of Lausanne have created an artificial eye comparable in performance to the eyes of insects such as fruit flies. The invention opens up great opportunities for robotics and medicine, where high-speed miniature video sensors are especially in demand.

For the first time, engineers have overcome the problem of accurately aligning photoreceptors and other optical components on a curved surface. Thus, thanks to the use of microelectronics stacked in layers, it was possible to copy the complex structure of the insect's eye, albeit in large in the same dimensions.

Insect eyes are very different from human eyes: in humans, the eye consists of a single "objective lens", while in insects the eye consists of many tiny objective lenses. Of course, the human eye has a higher resolution, but the insect eye has a larger field of view, and a faster response to movement. Engineers need such video systems so that, for example, robots can instantly survey large spaces and evade obstacles with lightning speed.

The Swiss were able to create a prototype of such a device and called it CurvACE. The tiny electronic eye weighs just 1,75 grams and shoots at 150 frames. CurvACE is capable of working in high or low light mode, consumes less than 0,9 W and takes up only 2.2 cm3, which allows it to be integrated into even small robots. It is integration with robots that will be the next step for scientists. In addition to robotics, it is supposed to be used to create "smart" fabrics that change shape and provide maximum comfort, as well as to create security systems and texture recognition technologies. In general, there are many applications for CurvACE, for example, in the military they can be used in homing missiles and active protection systems, and in aviation - for collision avoidance systems.
