Why are eyebrows needed?
This is a natural “headband” that we inherited from our ancestors. Eyebrows prevent acrid sweat and raindrops from rolling down from your forehead directly into your eyes. There is a possibility that the invention of umbrellas and hats, as well as the ruthless evolution over the coming millennia, will remove eyebrows from the list of organs necessary for survival and procreation. Because of this, women of the fourth millennium will no longer need to track discounts on plucking and styling on beauty salon Instagrams.How does dirt appear in the navel?
The accumulation of dirt in the navel is - no joke - the most mysterious physical process on the human body. Austrian chemist Georg Steinheiser investigated the formation process and composition of “umbilical mud” and published the results of his scientific research in 2010. It turns out that during the day, the hairs around the navel collect fibers from clothing and push them inside, where they mix with dust particles, beads of sweat and microscopic particles of skin, falling into clumps. To combat this scourge, says Steinheiser, you can either shave the hair around the problem area or get a piercing: the metal will repel dirt and there will be nothing to pick out in the shower in the evenings.
What does the subway smell like?
Creosote is a special chemical that is used to lubricate wooden sleepers and other subway parts. In the quantities in which it is in the air at stations, it is non-toxic and does not cause any unpleasant effects, except for reactions in allergy sufferers. In the subways of other cities (New York, Tokyo, London and even CIS cities - Minsk and Kyiv) this characteristic smell is not present.
If the mother of Russian cities is Kyiv, then who is the father?
First, we need to figure out why Kyiv is still a “mother”, despite the masculine gender. The pre-revolutionary spelling of Kyiv is “Kiev”. The hard sign at the end did not sound anything in the 19th century, but indicated the hardness of the previous consonant sound. But in IX it was pronounced as an unstressed “o” (for example, like the first two “o” in the word “milk”). During the reign of Prince Oleg, who called Kyiv “the mother of Russian cities,” the word was read as “Kieva” and belonged to the feminine gender. The pope of Russian cities, according to historians, is Novgorod. It was built before Kyiv, and served as an important trading hub - it was the beginning of the legendary route “From the Varangians to the Greeks.”
Do penguins have knees?
There are two sets. The first is the so-called tarsus, which looks like a backwards-turned knee, which almost all birds have, and a real functional knee that connects the femur and tibia.
The problem is that the penguins' tarsus is too close to the foot, and the knee itself is too close to the body. Therefore, the lower legs of penguins look like a solid, rigid structure. 
Where does the excavated soil go after the construction of the metro?
She doesn’t disappear anywhere without a trace. Depending on the quality of the resulting soil, the soil is sent either for processing and disposal to technical enterprises, for example, to construction sites in Moscow and the region, or, if it is of good quality, for landscaping parks and forest areas.
What dreams do blind people see?
People who are blind from birth actually see dreams that do not have visual images. Dreams may contain sounds, smells and touches in various combinations, but they will not even have color or light elements. People who have lost their sight during their lifetime experience normal dreams. Their brightness decreases year after year: colors disappear and images blur, until eventually they fade to zero.
Why do traffic police officers have striped batons?
The contrasting black and white coloring is equally noticeable both in the city and in the field at any time of the day and in any weather. The traffic police came to the idea of painting the batons black and white 77 years ago. Before this, back at the beginning of the century, until traffic lights appeared and the traffic flow grew to the modern endless traffic jam for the entire city, traffic controllers made do with first all-white and then red-yellow wands, similar to lightsabers from Star Wars. . Then the USSR launched a bold but unsuccessful experiment: for several years they made do with white gloves and a special set of gestures. It was after the fiasco of this venture that the traffic controllers were given the famous black and white sticks.
What is the most popular word in Russian?
A special organization of linguists that monitors the state of the Russian language found out in 2014 that the most popular word in the Russian language is the interjection “damn”, which is used in speech even more often than the pronouns “I” and “you”. This says a lot about the state of modern Russian speech.
Will a gun fire in space?
It will definitely shoot once. A bullet, devoid of air friction, gravity and other obstacles, will fly for a very long time and very far (quite likely millions of kilometers) until it falls into the gravitational zone of a star or extinguishes inertia in another way, but the shooter will have to fight with the recoil from shot, spinning around its axis and coping with nausea and disorientation. The second, third and other shots may well not happen: in order for some parts of the gun to work as required, they need an air gap to compensate for the friction of the parts. So every shot in space will render the gun unusable a thousand times faster than on Earth.
What causes "butterflies in the stomach"?
Adrenalin. For the brain, falling in love is very little different from other types of stress, such as grief or danger. This is why lovers eat little and sleep poorly. As soon as a person sees a loved one, the brain recognizes this as a stress signal and begins to pump adrenaline through the vessels. Please note: you most likely experienced the same sensations in your stomach before an important exam or before an important interview.
Why don't people sneeze in their sleep?
First, you need to understand how people sneeze: the brain receives information about irritation, transmits a signal to the chest muscles to fill the lungs with air, closes the holes in the throat and gives a signal to exhale. The air ends up exploding through the nasopharynx. It is impossible to sneeze in a dream, because problems occur at the very first stage: the brain receives a signal about irritation, but due to the fact that the nervous system works in a suppressed “sleep” mode, it cannot do anything about it except to wake up the owner, if the irritation is strong enough. And then, you won’t be able to sneeze immediately after getting up: the nervous system has not yet entered working mode.
Why are some dreams so difficult to remember?
During sleep, norepinephrine is not released - a hormone that, among its other duties, is responsible for fixing memories in long-term memory. An interesting detail: norepinephrine is released during lightning stressful situations: injuries and burns, as well as during serious nervous shocks, states of anxiety and fear. This is why nightmares and disturbing dreams are much more memorable than good dreams.
Why do some drinks taste bad after brushing my teeth?
The toothpaste contains sodium lauryl sulfate. It is added as a foaming agent, which makes brushing your teeth easier and distributes the paste more evenly throughout the mouth. The substance is not considered harmful, but may cause an allergic reaction or irritation. Another thing is that upon contact with the tongue, sodium lauryl sulfate suppresses the receptors responsible for sweetness. In addition, the component temporarily destroys the phospholipid layer, which suppresses the bitterness of food. So it turns out that the taste of food and drinks that a person consumes immediately after thoroughly brushing his teeth changes beyond recognition and not for the better.
Why does ice cream hurt my forehead?
The effect is called “brain freeze” and is observed in a third of people living on earth. Unpleasant pressing sensations in the forehead or behind the ears are caused by the fact that from the cold in the mouth (specifically in the palate), the brain is “scared” that the cold will soon reach it, and begins to urgently pump warm blood to itself. Because of this, blood flow is disrupted for some time, and unpleasant sensations arise in the head. In science, the effect is called sphenopalatative ganglioneuralgia. You can make warning stickers and use them to mark ice cream in stores.
What happens to the pages of deceased people on social networks?
In most cases - nothing. There is still no automatic deletion of a page after a certain period of inactivity in many social networks. For example, pages on Facebook, Odnoklassniki and VKontakte remain forever. However, Twitter deletes a profile in which no new posts have appeared for more than six months. In other cases, pages change status. Facebook allows you to turn a user profile into a “memorial”. To do this, you need to send a copy of the death certificate to the network administration. The status of the page will change - the inscription “In loving memory of...” will appear, and you can continue to leave comments and entries on the wall. When changing status, access to personal correspondence is not transferred to either relatives or other close people. Your secrets will definitely remain yours forever. A single solution to the problem of the social network has not yet been developed, but in the coming years it is already worth having in stock: around 2050, the number of pages of the dead will be equal to the number of profiles of the living, and then the ratio will change in favor of the dead.

There is a planet covered in burning ice. Not dry, but incredibly hot. On this planet, called Gliese 436 b, temperatures hover around 300 degrees Celsius, but the ice doesn't melt. The point is gravity - it is so powerful that it compresses water and keeps it in a solid state.
Radiation exposure can be measured in bananas. This is called the “banana equivalent”. The fact is that bananas are naturally radioactive due to the potassium-40 they contain. Banana equivalent is defined as the activity of the substance introduced into the body when eating one banana. And an X-ray of a tooth, for example, is approximately 50 banana equivalents.
