What are the sizes of the planets?

A planet is very different from a star. A star is a huge ball of hot gases that release heat and light. A planet is a much smaller celestial body that shines by reflected light. Let's start with the planets closest to the Sun.

The first one is Mercury. Mercury's diameter of 4640 km is almost the width of the Atlantic Ocean, that is, it is only a fraction of the size of the Earth.

The next planet is Venus. It is almost the same size as the Earth. Its diameter is 12160 km, while the diameter of the Earth is 12660 km.

By the way, such a strange fact is known that Venus rotates in the opposite direction, that is, from east to west.

The next planet is our Earth and then Mars. Mars shines with a reddish light. Its diameter is 6720 km, which is slightly more than half the diameter of the Earth. Some parts of its surface look like lunar landscapes, with large craters apparently formed by fallen meteorites, but there are also giant volcanoes and valleys, which proves the possible geological activity of the planet.

Jupiter - the next planet - is far from the Sun. It takes him 11,9 years to complete one orbit. Jupiter is the largest of the planets. Its diameter is 141 km, almost 920 times the diameter of the Earth.

Saturn, following it, is also a giant. Its diameter is 120 160 km. This is almost 9 times more than the earth. Saturn is unusual in that it is surrounded by a group of flat rings. These rings are made up of billions of tiny particles.

The next planet, Uranus, is much larger than Earth. Uranus is slightly tilted to the side: its axis is tilted at an angle of 98° to its orbit. (The Earth's axis is tilted at an angle of 23,5°.)

Next comes Neptune, a planet with a diameter of 48 km.

And finally, the last known planet is Pluto, which is believed to have a diameter of 3000 km. It is so far from the Sun that for Pluto it is just a bright star in the sky.

Who and when sold the Eiffel Tower for scrap?

In 1925, the Czech Viktor Lustig pulled off a scam to sell the Eiffel Tower. Having gathered several businessmen at a secret meeting, he announced that the government could no longer maintain the tower and was forced to hand it over for scrap. His victim was Andre Poisson, who paid a huge amount in cash, and after he recognized the deception, he did not even go to the police, fearing shame in business circles. A month later, Lustig returned to Paris and sold the tower again. True, the new buyer nevertheless turned to the police before completing the transaction, but the swindler managed to avoid arrest. After emigrating to the United States, Lustig continued to engage in fraud and ended up in Alcatraz.

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. ... >>

Qualcomm S7 and S7 Pro headphones 26.10.2023

Qualcomm Corporation has introduced new audio platforms designed specifically for headphones and speakers - Qualcomm S7 and S7 Pro Gen1. These innovative chips promise optimal use of artificial intelligence algorithms, thus providing the best audio experience.

Benefits of the new platforms include a six-fold increase in overall performance and more than a hundred times faster AI algorithm calculations compared to the previous generation.

Particularly noteworthy is the Qualcomm Expanded Personal Area Network (XPAN) technology and micro-Wi-Fi connectivity introduced in the S7 Pro model. This innovation extends indoor connectivity while also supporting lossless music streaming at up to 192 kHz. Unlike Bluetooth, which is limited to 48 kHz at a distance of up to 10 meters, the new XPAN technology breaks new ground.

Dino Bekis, vice president of Qualcomm, noted: “When we lowered power consumption and added Wi-Fi support to the headphones, we were able to stream 96 kHz audio over Wi-Fi while maintaining 10 hours of playback on a 50 mAh battery. This way, we can transmit lossless audio over Wi-Fi at the same power consumption as lossless audio over Bluetooth."

New Snapdragon Sound technologies will be integrated into new Qualcomm products such as Snapdragon 8 Gen 3 processors (for smartphones and tablets) and Snapdragon X Elite processors (for laptops), delivering a new level of wireless audio. Qualcomm partners, including brands such as Audio-Technica, Bose, Edifier, Fiio, Jabra, LG, Master & Dynamic, Shure and others, will provide compatible models for use with Snapdragon Sound technology.
