For everyone and about everything. Interesting science facts for kids

Nowadays, most schoolchildren, unfortunately, have very stupid, low and primitive values ​​and interests. Perhaps every second person now is either a hype fashionista, or a redneck ("boyish" style, speech, behavior, etc.), or anime fans, people from public places like "4(2)chan", " Oatmeal, sir!" and the rest are some kind of rabble, groups of people in whose interests there is something stupid, gregarious and stupid. All this together and separately: “sharyu, fashionista, chan, gear, bro, brother, fighter, coons, kitty, fu, bang, newfangled music (cloud, thrill: Pharaoh, Kizaru, FACE, Bones, etc. ), chicks, chicks with a bob, well, it just makes me want to puke. It’s so funny, pathetic, defective, to “eat” everything that is dictated in popular public pages on VKontakte and also despise and ridicule everyone who does not share your type of consumed shit. Well, those who spend a lot of time in the open spaces of “contact” understand perfectly well who I’m talking about and what communities of people I’m talking about. By the way, I was once also almost obsessed with hype fashion, memes, and so on. , this did not last long, because I am perfectly capable of analyzing, evaluating and eliminating what brings me to the bottom, to the same level as 90% of my peers.

It came out quite rude and harsh, but it’s all true, which is very, very sad.

I am 14 years old, I study in the 8th grade. And you know, all my classmates, parallel and even people from older classes, are passionate about some stupid, strange, worthless things. I observe, I see their manner of communication, behavior, tastes, values, opinions, positions and I realize that everything is very, very bad. I am sad to see that most of them are completely illiterate, naive, ignorant, not interested in self-development, or in their future, or in personal improvement, or in anything. They just live for themselves and live. And the worst thing that can happen is that they don’t need it, they don’t have the desire, they don’t care. They just exist indifferently and seem to enjoy it.

Maybe I was harsh and critical of everything, but this is the undeniable truth. Of course, there are also those teenage schoolchildren who, already at their age, are engaged in additional, versatile education, show critical thinking, have an adult and sober view of society, the world and what is happening in it, and the like (only if they are not pseudo-intellectuals and posers - I can’t stand them). I believe that such schoolchildren, truly interested in something worthwhile, are simply the highest value, rarity and salvation.

I don't have an overestimate, but I consider myself to be in that minority. Quite reasonable, I think))

I'm on this moment I try to devote as much time as possible to self-development and education. In addition to school education, I additionally read books (novels, books on science, prose, etc.), I also took for myself very good habit watch YouTube channels about science, critical bloggers, channels exposing absurdity and pseudoscience, science pop, video lectures, lessons, advice, and other channels on topics that interest me. I highly recommend it).

Well, in general, I am a very versatile, multifaceted and, at some points, contradictory person. I am hyperactive, cheerful, sociable, sociable, but, most often, only with my social circle, which never exceeds 4-5 people. I have bipolar affective disorder (BAD), which affects my assessment of myself and others, but I don’t consider it a terrible problem.

I love interesting, educated, competent, charismatic, ambitious people who have their own style, position and views. As for music, I am a music lover. I love rock, metal, blues, jazz and their branches, subgenres (I don’t really understand this, there may be a semantic, terminological error somewhere). Favorites: foreign indie rock, heavy, nu metal, pop rock, rock and roll, blues rock, hard rock and the like. I also love Russian music.

IN Lately I am tormented by doubts, thoughts about future profession and about your direction. I creative person, very different, and I don’t know what to choose. But I have definitely decided on one thing - this English language. At this time I am trying to study it in more detail, better. This language is, in principle, easy for me. My level of knowledge of English is now above average (well, this is compared with peers). Undoubtedly, we need to move even further.

I want to connect my life with travel, perhaps I will be a translator. I also really like the art of photography and music. I think I will highlight the main and secondary things for myself, but I will definitely not neglect anything. I will try to do everything possible so that all this comes true and does not remain just empty words and dreams.

I am not going to live a boring, unpromising, primitive and routine life. I’m not a particularly family person, but love is important to me and I’ll definitely have one child, after 33 years) I think that life should be lived interestingly, usefully, richly, brightly, freely and most importantly, happily. This is the kind of schoolgirl I am.

Most of the knowledge acquired at school will never be useful to us. Most of this we will never even remember. And yet some crumbs of “useless” information will remain in memory. Paradoxically, it is thanks to them that we feel educated people. The luxury of keeping in mind not only vital information, but also “information surplus” increases self-esteem and gives a feeling of intellectual competence.

And “unnecessary information” surprisingly turns out to be the most interesting. This interest can become a magic key for children to huge world science, which often hides behind boring formulas and incomprehensible definitions.

In this article, we have collected nine scientific facts that can be used in mathematics, physics, geography, chemistry and biology lessons to clearly show: science is not something abstract from real life, but the situations we face every day.

Fact No. 1. On average, an ordinary person travels a distance equal to three Earth equators in his life

The length of the equator is approximately 40,075 km. Multiplying this figure by three, we get 120,225 km. At average duration life at 70 years, we get about 1717 km per year, which is a little more than five kilometers per day. Not that much, but it adds up to a lifetime.

On the one side, practical application this information does not have. On the other hand, it is much more interesting to measure the distance traveled not in meters, steps or calories, but in equators. And calculating the percentage of the length of the equator will attract attention not only to geography, but also to mathematics.

The following two facts may also be useful in mathematics lessons. Using the first, you can calculate the number of children in a parallel or even in an entire school born on the same day.

Fact #2: If there are 23 random people in a room, then the probability that two of them will have the same birthday is more than 50%.

And if you bring 75 people together, then this probability reaches 99%. There can be a 100% chance of a match in a group of 367 people. The probability of a match is determined by the number of pairs that can be made from all the people in the group. Since the order of people in pairs does not matter, total number such pairs are equal to the number of combinations of 23 by 2, that is, (23 × 22)/2 = 253 pairs. Thus, the number of couples exceeds the number of days in a year. The same formula calculates the probability of coincidences for any number of people. This way you can estimate the number of children born on the same day in a parallel school or even in the entire school.

Fact No. 3. The number of living organisms in a teaspoon of soil is greater than the entire population of our planet.

One square centimeter of soil contains billions of bacteria, fungi, algae and other organisms. About 60 million bacteria live in just one gram of dry soil. Nematodes, or roundworms(the most famous of which are roundworms and pinworms) in the same amount of soil is much less - only 10 thousand. A figure incommensurate with the human population, but no less unpleasant for that.

Practical application of information: Wash your hands thoroughly after caring for your indoor plants, as well as after working in the garden or vegetable garden. High zone bacterial danger- sandbox on any playground.

Fact #4: The average toilet seat is much cleaner than the average toothbrush.

The bacteria on your teeth live at a density of about 10 million per square centimeter. The amount of bacteria on the skin varies depending on the part of the body, but in any case it is much less than in the mouth.

But there are no bacteria on the skin of frogs at all. The reason for this is the mucus secreted by the frog and containing strong antibiotics. This is how frogs protect themselves from the aggressive bacterial environment of the swamps in which they live.

A person is much less adapted in this regard, so it is recommended to change toothbrushes every couple of months.

Fact No. 5. In the evening, a person becomes 1% shorter compared to his “daytime” height

Under load, our joints tend to compress. With a normal lifestyle, by evening a person’s height decreases by 1-2 cm, which is approximately 1%. The decrease is short-lived.

The maximum reduction in height occurs after weightlifting. Changes in height can be three or more centimeters. This is due to compaction of the vertebrae.

Fact #6: Diamonds can be produced from peanut butter using very high pressure.

Scientists from the Bavarian Research Institute of Geophysics and Geochemistry tried to simulate in the laboratory the conditions of the Earth's lower mantle, where at a depth of 2,900 kilometers the pressure is 1.3 million times higher than atmospheric pressure. During the experiment, some innovative ways of producing diamonds were discovered. According to one hypothesis, diamonds are formed from carbon under the influence of very high pressure. Carbon is found in almost all foods. And since the researchers only had peanut butter on hand, they tried it. Unfortunately, hydrogen, which is bound to carbon in peanut butter, slows down the process significantly, taking several weeks to produce even a small diamond. Thus, scientific thought proves that the most incredible transformations are quite possible.

Fact No. 7. The height of the Eiffel Tower can change by 12 centimeters depending on the air temperature

An iron rod 300 meters long lengthens by 3 mm with increasing temperature environment by one degree.

This is exactly what happens with the Eiffel Tower, which is approximately 324 meters high.

In hot sunny weather, the iron material of the tower can heat up to +40 degrees, and in winter in Paris it cools down to approximately 0 degrees (severe frosts are rare there).

Thus, the height of the Eiffel Tower can fluctuate by 12 centimeters (3 mm * 40 = 120 mm).

Fact #8: A typical microwave oven uses much more energy to keep its built-in clock running than it does to reheat food.

While in standby mode, a modern microwave uses approximately 3 watts per hour. Already 72 W per day comes out, and if we multiply this number by thirty days, we get an energy consumption of 2160 W per month.

If we assume that we use the microwave every day for 5 minutes, we get 150 minutes or 2.5 hours per month. Modern stoves consume about 0.8 kW/hour in heating mode. It turns out that with this use, the energy consumption directly for heating food is 2000 W. If you purchase a more economical model that consumes only 0.7 kW/hour, we get only 1.75 kW per month.

Fact No. 9. The first computer mouse was made of wood

Sometimes we are just curious to know the fate of the objects that we use every day.

A computer mouse in our usual design was introduced to the world in 1984 by Apple. Largely thanks to her, Macintosh computers became incredibly popular. But this small but such a necessary device begins its true history 20 years earlier.

In 1964, engineer Douglas Engelbart from Stanford developed a manipulator to work with operating system oN-Line System (NLS). Initially the device was a wooden box self made with two wheels inside and a button on the body. After some time, the device appears with a third button, and a couple of years later Engelbart receives a patent for his invention.

Then Xerox comes into play, but its modification of the computer mouse costs about $700, which does not at all contribute to its mass distribution. And only Steve Jobs’ company is able to develop a similar device with a cost of 20-30 dollars, which was included in daily life billion people.

Teachers can use this material in preparing and conducting the most various events: competitions and quizzes, thematic classes and conversations, messages, oral journals, “The Amazing is Nearby” reviews, etc.

Cognitive information is designed to interest students and broaden their horizons. The material was prepared according to various sources: popular science and children's fiction, scientific and educational magazines, periodicals.

. Where is the center of Russia?

According to geographers, the center of Russia is located in the Krasnoyarsk Territory, southeast of the city of Norilsk. They decided to mark the center of Russia with a seven-meter obelisk with a double-headed eagle on top.

. Can animals dance?

Many animals are excellent dancers. The ballet couple is reminiscent of storks during their mating dance. Cabbage butterflies hover merrily around each other. Moving with all eight legs, the spiders perform dashing leaps and jumps. Small seahorses, slowly approaching and diverging, bow as if performing a square dance, or begin to spin slowly and smoothly in a waltz. Night moths resemble light fluttering around the stage in the spotlights of little dancers.

. Did the real Ilya Muromets ever live?

According to the folk calendar, September 28 according to the old style (or October 11 according to the new style) is the day of Ilya Muromets, who was considered a historical figure and was revered as a people's intercessor. Epics, unlike fairy tales (fiction), are based on real historical events. Historians do not deny that the epic hero Ilya Muromets could have a real prototype.

Ilya accomplished many feats, protecting the Russian land. And the hero was born not far from the glorious city of Murom in the village of Karacharovo, hence his nickname - Muromets.

Nowadays the city of Murom is located in Vladimir region, and the village has survived like this - Karacharovo. The bed (now dry) of the Oka River has also been preserved, which, according to legend, was once filled with stones by a young man, testing his brave strength. And modern Karacharites sincerely consider themselves descendants of Ilya Muromets, who presumably lived in the 13th century. From the legends we learn that the hero was a believer - after finishing his military service, he gave everything he had acquired to churches and devoted himself to serving God. He traveled a lot throughout Rus', and ended his life in the Kiev-Pechersk monastery. The ancient chronicles that have come down to us speak of the Venerable Ilya Muromets, nicknamed Chobotok, whose biography is similar to the life and exploits mentioned in the legends about the Russian hero Ilya Muromets.

The chronicles also say that the relics of the famous hero rest in Kiev-Pechersk Lavra. In the last century, historians decided to check the authenticity of the document and examined the approximate burial sites. In one of the tombs they found the remains of a broad-shouldered, heroically built warrior. True, his height was slightly above average - 177 cm. But in the old days, Russians rarely grew beyond 160 cm. Therefore, by those standards, the deceased looked simply like a giant.

Judging by the remains, the warrior had a severe curvature of the spine in lumbar region. From the epics we know that Ilya sat on the stove for almost 33 years, the passers-by healed him, and blessed him for military deeds. The hero took part in many battles. The dried-up body of the found warrior retained traces of many wounds, and he died, presumably, from a mortal wound from a dagger or spear at the age of fifty.

The notes of the pilgrim Leonty, preserved from the 13th century, tell us how he visited the last monastery of Ilya Muromets: “Seeing the brave warrior Ilya Muromets incorruptible, under the cover of gold. He is tall like today's large people, left hand it is pierced with a spear, and the right one depicts the sign of the cross...”

The Orthodox Church canonized the hero, and the memory of St. Elijah of Muromets is celebrated, according to church canons, on December 19.

. What did Sadko play?

We all remember the epic about the Novgorod guslar Sadko. Historians even managed to find a prototype of the epic hero: the chronicles preserve information about Sotko Sytinich, who lived in the second half of the 12th century. And this is what Sadko’s harp looked like, for a long time remained a mystery. About 30 years ago, during excavations in Novgorod, archaeologists recovered from the layers of the 12th century an unusually shaped wooden box decorated with carvings. Based on its shape and the hole for the pegs, scientists determined that this was an ancient harp.

. How old is the anthology?

The first anthology appeared around the 4th century AD, thanks to the Greek grammarian Helladius. It consisted of excerpts from the works of many Greek writers, “useful for teaching.” Since then, all the “useful for teaching” collections of scientific and literary works began to be called anthologies.

. Do fairy tales come true?

Many fairy tales talk about how one or another fairy-tale character hears and sees thousands of miles away. Today this is done using radio, radar, television, satellite dish, etc.

Remember about “dead” and “living” water? “I took” dead water and became old, decrepit, lost my vitality... Can you guess what I’m talking about? Of course, about alcoholism and drug addiction!

“Living” water in our real life can be considered healing tinctures on various plants: ginseng root, Rhodiola rosea leaves, etc. They cure many ailments, expel old illnesses, give strength and energy, cleanse our body of harmful substances and so on.

In fairy tales, only one can make it rain to an experienced magician or a sorcerer. According to ancient beliefs, this was the direct responsibility of the pagan deity Dazhdbog, then the Thunderer Ilya and other saints. Today man has learned not only this. Rain is produced by using carbon dioxide launched from a rocket into a thundercloud. With the help of airplanes they learned to disperse thunderclouds.

Just like in fairy tales, modern “alchemists” (doctors) have learned to restore life to people. Temporary cardiac arrest for 7-10 minutes, that is clinical death, is now reversible.

. Science fiction ideas - myth or reality?

Scientists have calculated that out of 108 fantastic ideas of Jules Verne, only 10 were unfulfilled, out of 86 ideas of H. Wells - 9, and out of 50 ideas of Alexander Belyaev - only 3.

The most striking example of scientific foresight was shown by our great compatriot Konstantin Eduardovich Tsiolkovsky. According to cosmonaut Yuri Gagarin, the scientist even described the sensations of a person in a state of weightlessness with amazing accuracy.

. What do gnomes eat?

Everyone knows healing properties carrots. Did you know that in the Middle Ages carrots were considered a delicacy for gnomes - fabulous little forest people?

There was a belief: if you take a bowl of steamed carrots into the forest in the evening, then in the morning you will find an ingot of gold instead of carrots. At night, the gnomes will eat carrots and pay generously for their favorite food.

Try feeding the little people, maybe you'll get lucky. But a miracle will happen only if you believe in fairy tales and magic.

. When did carrots appear?

Carrots as a cultivated plant began to be grown in different parts of the globe long before our era. Archaeological finds prove this. Carrots were found in fossilized form in pile buildings near Bern in Switzerland. Experts believe that it lay there for at least 30-40 centuries.

Behind long years cultural cultivation has changed the appearance of this vegetable. I changed the carrots yellow to orange and red, it became more juicy and sweet, and there was a significant increase in vitamins and carotene.

There is especially a lot of it in red varieties of carrots. The most valuable nutrients in carrots not only stimulate growth and improve vision, but also cure many diseases. So eat more carrots - you will be cheerful, cheerful and healthy!

. Can animals build nests?

Quite. For example, fish. In warm tropical seas, many of them weave nests from algae, thereby protecting their future offspring - first eggs, then fry. Often, enterprising fish line their nest with pebbles and shells for greater strength and protection, turning the temporary home of their offspring into a real fortress.

. What should ancient schoolchildren learn?

What knowledge would Alexandrian schoolchildren have had 2000 years ago? First, know the names of famous people: legislators who proposed useful laws, sculptors, artists, inventors of machines and mechanisms. In addition, they were required to know the islands of the Mediterranean Sea, the mountains and rivers of Europe, Asia and Africa, as well as the seven famous wonders of the world. In a document found during excavations in Alexandria - papyrus with ancient Greek writings - it was especially emphasized that all these miracles were created by the mind and hands of man.

. About the seven wonders of the world.

Every modern schoolchild should have an idea of ​​the seven wonders of the world. “Seven Wonders of the World” was the name given in ancient times to seven works of architecture and sculpture that surpassed all others in size, shape, decoration, and so on.

The first wonder of the world is the Temple of Artemis at Ephesus.

The second wonder of the world is the statue of Zeus at Olympia by Phidias.

The third is the Colossus of Rhodes - a huge copper statue of the god Helios (more than 70 meters high), erected by the Greeks 300 BC. e. at the entrance to the harbor on the island of Rhodes.

Fourth - pyramid-tomb Egyptian pharaoh Cheops, built more than two thousand years BC. e. on the west bank of the Nile.

Fifth - the hanging gardens of the Babylonian queen Semiramis.

The sixth is the tombstone of the Carian king Mausolus in Halicarnassus, erected in 351 BC. e. (length 37.5 meters, width 26.5 meters, height 42 meters). For fifteen centuries (before its destruction by an earthquake), this structure aroused everyone's amazement. From him came the word “mausoleum” to denote outstanding funerary monuments;

And finally, the seventh wonder of the world - the lighthouse tower, erected at the end of the 3rd century BC. e. on the island of Pharos at the mouth of the Nile near Alexandria and was about 180 meters high.

. When did ice cream appear in Rus'?

A long time ago. Only ancient ice cream was very different from modern ice cream in its own way. appearance and taste. Our ancestors sculpted various funny figures from cottage cheese with sour cream and sweets and exposed them to the cold. But more and more peasant people in the villages enjoyed such ice cream. In rich houses, ice cream was served no worse than today. Famous historical fact using ice cream for insidious and cunning purposes. The future Empress Catherine II on the eve palace coup lured Emperor Peter III to her place, promising to treat him with this cold delicacy.

Scientists have not yet been able to establish the exact date of the appearance of ice cream. It is known only from the chronicles that have reached us that Alexander the Great loved to treat himself to fruit juice with snow, which was specially delivered to him in Persia. A similar product was described by Hippocrates. Ice mixtures were also adored in the time of Nero. The Venetian traveler Marco Polo brought a recipe for making ice cream from Ancient China to Europe. At first, the delicacy was available only to very rich nobility. The recipe for making ice cream was kept in big secret, the disclosure of which was punishable by death.

In 1851, in America, in the city of Baltimore, the world's first ice cream factory was built.

. Why is a popsicle called a popsicle?

This cold delicacy is almost 85 years old, and all of humanity owes its appearance to the French. One of the founders of the company that produced cheese, Charles Gervais, after a trip to America and getting acquainted with American fruit ice cream, came up with the idea of ​​filling a candy bar with chocolate and “putting” it on a stick.

At first, the ice cream was nameless, that is, it did not have a special name. It appeared only after Gervais began selling his “invention” in one of the then few cinemas in Paris, where a film about the Arctic and the Eskimos living in it was shown for a long time.

Soon this cinema became known to all residents of the French capital, and ice cream with light hand One of the Parisian wits began to be called “Eskimo”.

. Who is a teacher?

Translated from Greek, the word “teacher” means “guide of a child.” In ancient times, the duties of a teacher included accompanying the offspring of noble parents from home to the gymnasium. He made sure that the ward came to classes on time, waited for him until the end of classes and took him back.

. Do cows like music?

Recently, American scientists conducted a series of experiments to find out whether cows respond to music, and came to amazing results. It turned out that cows not only love music, but also have a delicate taste. Thus, to the sounds of classical music, milk yield increases by 5-10%, but animals are completely indifferent to modern music.

. Are there animal monuments?

Exist. Many animals have merits for humanity. For example, in the USA, Holland, Denmark and Romania there are monuments to a cow, and in Paris and Tokyo - to a frog. In Russia in St. Petersburg There is a life-size monument to a small siskin; a monument to a bull was recently erected in Saratov, and a monument to a goat was erected in Uryupinsk.

. Who invented the day off?

Really - who? It is believed that the first “inventors” of a seven-day week with one day of rest were the Babylonians. On this day, residents of the country had to perform religious ceremonies and avoid physical labor.
