What is the fastest mammal on earth?

Man can move on the ground much faster than any other mammal... but not at the expense of his own legs! Even the fastest runner of our time can seem very slow compared to some animals.

A person can run at speeds up to 35 kilometers per hour. But even such a slow animal as an elephant or a rhinoceros can reach speeds of up to 40 kilometers per hour.

A racehorse, which is considered a fairly fast animal, can run at speeds up to 80 kilometers per hour. The fastest greyhound can race at a speed of about 60 kilometers per hour.

If we want to know the true speed of a mammal, then we need to think about animals such as antelopes and gazelles. These animals can reach speeds of up to 100 kilometers per hour. But the speed champion of the animal kingdom is the cheetah. The speed of this animal exceeds 110 kilometers per hour! Of course, they can maintain this speed for a distance not exceeding one mile, after which they switch to a slower speed.

 Random interesting fact from the Great Encyclopedia:

Why is fire hot?

The answer to this question is the very definition of fire. Fire accompanies combustion - a rapidly occurring reaction in which heat and light are released. There are several kinds of chemical reactions that can result in the phenomenon we call fire. The most common of these is the reaction between oxygen and fuel. If heat and light are released as a result of it, we get fire. Three things are needed to start a fire.

The first is fuel, the second is oxygen. Fuel quickly begins to combine with oxygen. When wood is burned in a fire or gas is burned in a stove, there is a vigorous interaction between the fuel and the oxygen in the air. The third thing we need to start a fire is warmth. Paper or wood cannot catch fire simply by being exposed to air. Usually this requires a lit match. When the paper is heated sufficiently, oxygen begins to actively react with it - and the paper is engulfed in flames.

Each type of fuel can ignite only at a certain temperature. It is called its ignition temperature. Imagine a wooden stick being heated to ignition temperature by a burning match. It's not all covered in flames. The reason for this is that oxygen does not come into contact with the rod as a whole, but only with its upper layer, which turns into a gaseous substance under the action of heat. As the heating continues, the gas particles and oxygen in the air move very quickly. Under these conditions, gas and oxygen particles combine very easily and quickly. Heat and light are emitted: we have received fire.

With some types of combustion, no light is emitted. If the fuel reacts slowly with oxygen, only heat is released. This happens, for example, when rust eats iron. Rusting is just a very slow form of burning, so slow that you can't even feel the heat it gives off. Fire is a rapid burning, or ignition, and when ignited, both heat and light are released.

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 ... >>

TV controlled by the power of thought 23.06.2015

The British broadcasting corporation BBC has demonstrated a prototype of the Mind Control TV system, which allows you to control the TV in the literal sense of the power of thought.

To use the system, you need to put a special headset on your head to take an electroencephalogram. This device uses integrated sensors to record the electrical activity of the brain. The accompanying application generates control commands based on the received data.

In the Mind Control TV prototype, the user needs to reach a certain level of concentration in order to perform the desired action. This is indicated by a scale similar to a volume increase bar.

During the experiment, the system alternately showed screensavers of five channels, lingering on each of them for 10 seconds. Volunteers were asked to make a choice by gaining the required level of concentration.

In general, the Mind Control TV complex showed positive results, although channel switching was easy for some subjects, and difficult for others. It is assumed that in the future, such a system will make life easier for people with various disorders of hand motility, as well as paralyzed patients.
