10 Scientific Facts That Prove We Know Little About the World

Even if you have several academic titles, a high intelligence quotient (the famous IQ) and the nickname of “walking encyclopedia”, the world will always have interesting facts under its sleeve that you have never heard about or that you had not even thought about. And it seems that this reserve is inexhaustible! Have you ever heard that there is an animal that has ultraviolet particles in its beak? It is about these and other data that our post addresses.

O awesome.club presents a series of very interesting information about our world and that you probably still don’t know.

“It is clear! For the fact that he is happy!”, would answer the experienced cat owners… and they are right. However, cats not only respond with a purr to caresses, they can also produce this sound in response to fright or hunger, express support and even cure some ailments.

Scientists have discovered that the purring frequency of our felines, on average, ranges from 50 to 150 Hz. But this frequency depends on the situation: when expressing gratitude or demanding food, the pet will produce sounds of different tones. Purring at a frequency from 25 to 150 Hz accelerates the healing of bones, tendons and relieves pain. Veterinarians also point out that, often, a healthy cat purrs next to a sick one.

What’s more, scientists also consider that cats evolved such a healing mechanism. By applying it at rest, the animal is performing “self-prevention”.

The flamingo is distinguished by its extraordinary anatomy: a large body with a long neck supported by long, slender legs. In addition, these birds can stand still for a long time by balancing on one leg. Why, after all, do they rest in such an apparently uncomfortable position?

This happens due to thermoregulation: the proportion of its legs that are not covered with feathers means that, on a windy day, the flamingo loses a lot of heat. Therefore, it hides the other leg in its plumage to warm it up. Furthermore, the result is that such a position is not at all uncomfortable for them: the special physiology of these birds prevents the leg from bending, so it manages to keep it straight without muscle tension.

Due to erroneous engineering calculations, the famous tower of Pisa began to lean to one side from the time of its construction in 1173. For many centuries, authorities tried to restore the balance of the building. In 1990 they even had to close access to tourists due to the danger, as the famous tower was about to collapse completely.

Over several years, the responsible engineers took various architectural and technical measures, fixed outriggers and careful earth work was carried out. Finally, experts came to the conclusion that with the help of engineering technologies, the tower for the first time in several centuries ceased to fall. Moreover, it is now straightening: in the last 20 years, the belfry has raised about four centimeters. The construction, as it is now, is super stable and it is not necessary to worry about the safety of people or the monument itself.

The ornithologist Jamie Dunning, from the University of Nottingham (in the United Kingdom), when studying puffins, intended to find ultraviolet particles in the plumage of the birds due to their belonging to the family Alcidae🇧🇷 However, by no means did I expect the birds’ beaks to light up as well.

With the help of the brightly colored beak, males attract the attention of females. In fact, most of the time the beak is unimportant and acquires a saturated hue only in the mating season. The fact that the puffins’ beaks (as the puffin is also called) are fluorescent shows that these birds still hide a series of mysteries.

Squirrels practically never store all their reserves in one place, as that would be too unwise. Usually, rodents disperse their hiding places over a very large surface. At the same time, they select their harvest strictly, leaving only fruit and seeds in good condition.

It is not enough just to bury the reserve; squirrels hide it by placing several leaves on top of them so that no one can imagine its existence. If an astute rodent notices that it is being pursued, it pretends that it is making one of these reservations and hides the food somewhere else.

Scientists have come to the conclusion that squirrels have a phenomenal memory and an incredible sense of direction, as they accurately find up to 95% of their “savings”. At the same time, their sense of smell almost does not help them: firstly, it is almost impossible to smell nuts from under a layer of ice and snow where they live. Second, rodents often ignore other people’s hiding places too confidently and seek only their own deposits.

Some (rare) people are born to work as super-secret agents, as they never leave any clues. However, in real life, this quirk brings more problems than benefits. It sounds silly, but the absence of an individual design on the fingertips is called adermatoglyphia and, to enter some countries where it is necessary to verify fingerprints, access is beyond complicated.

Today, in the world, there are 4 families that have this rare genetic disorder. This characteristic is related to a mutation of a certain gene during embryonic development. Scientists continue to make observations and raise hypotheses, however, they still haven’t discovered health problems in people who have adermoglyphics.

In the animal world, males must possess special qualities to attract a female’s attention. Bird researchers have already noticed an interesting trend: males with more striking and slightly more elaborate plumage are only able to emit monotonous signals, while those with more interesting vocal abilities are simpler and almost indistinguishable from females of other types. of birds.

Ornithologists assume that quickly developing two methods for conquest of females would be too hard work for evolution. Therefore, each type of bird had to make the choice in favor of a striking appearance or a fascinating song.

An innovative ice cream, known under the name of Kanazawa Ice, became very popular in Japan. And the reason is that this cold dessert does not melt and does not leave stains around it, even on the hottest days of summer.

Such an effect was only possible thanks to the polyphenols obtained from the extract of strawberries. The polyphenols, here, perform the function of emulsifiers, preventing the portions of ice cream, oil and water from mixing. It’s funny that those responsible, in general, did not plan to create an “inmelt” ice cream. The idea was to experiment with a new strawberry dessert.

If, by chance, at some point in your life you order green tea in the Azores, be prepared to observe a curious trick: directly, in front of your eyes, the water that has just entered the teapot turns gray and then , will begin to acquire a lilac hue, thickening to an intense purple color. Don’t be alarmed, the coffee shop owners don’t plan on poisoning you.

Boiling water, rich in deoxidized iron, reacts with the antioxidants in green tea. Such a “volcanic” drink is not only safe, but also pleasant in taste and extremely saturated with minerals.

When talking about the ancient Inca city, first of all, we remember its monumental walls and complex of buildings. However, expert Kenneth Wright argues that the most memorable detail of Machu Picchu does not lie in the architecture, but in the engineering. It should be remembered that the Incas did not use animal traction, steel tools or even wheels. However, they managed to erect stone buildings and also pave a surface between two mountain peaks.

Kenneth considers that about 60% of the construction of Machu Picchu is hidden underground. It consists of deep foundations of buildings sunk underground and fragmented stones used as drainage. Thanks to this incredible engineering work, the city is still preserved today.
