Do all cats purr?

When something smells delicious or you just feel good, you sometimes hum rather: "Mmmm! .." When the cat wants to express its pleasure, it purrs. The purring sound is produced by the vibration of the vocal cords. The cat draws air into the lungs, and it passes through the vocal cords along the way.

Thus, if desired, the cat can allow the vocal cords to vibrate with air pressure. When a cat doesn't want to purr, she doesn't use her vocal cords - and no purring! Of course, when we talk about a cat, we usually mean a domestic cat. But there are still many members in the cat family. Did you know that the tiger, lion, leopard, jaguar, coguar, ocelot, and lynx also belong to the cat family? As for the reproduction of various sounds, a domestic cat, in addition to purring, can also meow, howl and yell.

Other types of cats make different sounds. Lion and tiger can roar. Jaguar and leopard make a sound similar to a loud cough or bark. But the most interesting thing is that due to the different structure of some of the bones of the throat, neither a lion, nor a tiger, nor a jaguar, nor a leopard can meow! But all cats, regardless of their size, have the same body proportions. If you enlarge the photo of a cat to a large format, you will see that it is very similar to a tiger.

 Random interesting fact from the Great Encyclopedia:

Why do waves appear?

If you have ever spent time on the shore of a reservoir, you probably noticed that in calm weather there are almost no waves on the water, and on a windy rainy day there are many waves.

Here's how you can explain the appearance of waves on the water. The wind creates them. A wave is a way of moving one form of energy from one place to another. Some kind of force or energy is needed to create a wave, and the wind transfers this energy to the water.

When we observe the movement of waves - successive, one after another - it seems that the water also moves forward. But if a piece of wood floats on the surface of the water, we will notice that it does not move forward with the waves. It will only appear and disappear in waves. It will only move in the presence of wind or current. What is the movement in the wave? Basically, this is the movement of water particles up and down. This movement is transmitted towards the shore. For example, if you have a rope, you can create a kind of wave along its entire length. Wave-like movements run along the entire length of the rope, but the particles of the rope do not move forward.

Near the shore, the base of the wave hits the bottom, and the movement of the wave slows down due to friction. The crest of the wave continues to move, breaking down and forming surf.

Near the shore, the waves lose their energy. Stand in the waves near the shore, and you will understand what energy they have!

In waves, water particles move up and forward, pushed by the wind. Gravity then causes them to descend and return to their original position. It is these movements of the water that make the waves move. The distance between the crests of two waves is called the wavelength, its lowest position is called the sole.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

The robot will find water on the moon 30.10.2012

Astrobotic Technology Corporation has completed development of a full-size prototype of Polaris, a solar-powered robot that will search for water ice at the lunar poles. Polaris will be able to drill into the lunar surface and work in areas with long, harsh shadows and low sun above the horizon. Even though Polaris is a prototype, it has the same configuration as the rover that will land on the Moon's surface. The prototype will allow the Astrobotic team to conduct the necessary testing and improve the robot's vision and navigation systems, as well as its software, in the near future.

"This is the first rover designed specifically for lunar ice drilling," said William Whittaker, CEO and founder of CMU's Robotics Center. The technology needed to drill on the lunar surface was already being developed at the center, but none of the previous robots were planned to be sent into space.

Based on observations from NASA and India, it seems likely that there is a significant amount of water ice at the Moon's poles. This ice could be a source of water, fuel and oxygen for future expeditions. To find this ice, the rover must operate as close to the dark poles as possible, but still far enough away to be able to be powered by solar panels. Polaris has three large solar arrays to capture the light of the sun low on the horizon. On average, they are capable of generating about 250 watts of electricity.

The device weighs 150 kg and can accommodate drilling equipment and other payloads weighing up to 70 kg. The speed of its movement on two-foot wheels will be about 1 foot per second. The robot itself is made from aerospace-grade lightweight composite structural materials.

Scientists expect Polaris to drill 10 to 100 holes during the time it searches for ice. He will have about 10 days at his disposal, given that the lunar day lasts 14 days. However, if the robot proves capable of surviving the long, cold moonlit night, the search mission will be extended indefinitely.
