What is a "black hole"? The most difficult questions.

In order to find the answer to any question, today it is not necessary to go to the library and spend many hours searching necessary information. Modern Internet search engines offer many ways to do this quickly and efficiently.

As is known, in World Wide Web contained huge amount information, both necessary and useless for a particular user. In order to quickly navigate this diversity and not spend a lot of time sorting, there are so-called search engines.

One of the most popular and sought after search engines is Google. It is enough to enter a couple of keywords into the search bar, and the system will immediately return a huge amount of useful and interesting information By this direction, and sorted by degree of value and relevance.

An important condition for an effective search is the maximum precise definition keywords. It is necessary to be as detailed as possible, but at the same time, succinctly compose a request for information on which you want to find. If you want an answer to "where to buy red skis," don't ask "how to find colorful snow sports gear." Brevity is the sister not only of talent, but also of the search engine.

If you need to find some exact phrase or quote on the Internet, you need to enclose it in quotation marks - this is a command for Google to search the Internet exact match phrases, not individual words from her. If your memory fails you a little, and you are not sure that you remember the sentence exactly, you can insert an asterisk instead of the missing words, Google will understand you even perfectly. If an exact match is not necessary and you are happy with a selective match, just list keywords, separating them not with commas, but with a vertical slash icon.

It is not always possible to find comprehensive answers to some questions in a standard way. To solve this problem, there is such a convenient function as advanced search.

Go to the search engine settings by clicking on special icon with the gear on the right side of the screen and select the "Advanced Search" option. On a separate page that opens, fill out the menu lines with all the necessary parameters of your request down to the details. To the right of each field there is brief description with examples to simplify the task. Among additional settings You can mark such parameters as searching for pages in a selected language, in a specific country, by the date the information was updated. Here you can specify the site or domain within which you want to search, as well as possible place location of the search words on the page.

One of the quite interesting and useful functions- search for a match using a picture. For example, you have a photo of an actor you know or a logo of a company, but you just can’t remember, and for the past hour you’ve been racking your brains over who this person is or what’s hidden behind the brand. Search engine Yandex system simplified the task: go to the “Pictures” tab, select the “Search by picture” option, upload a photo from the gadget and in a couple of seconds the system will show all possible matches. In 99 out of 100 cases you will be able to identify the object.

Many answers to certain questions information regarding a specific brand or product can be found on the company's official website. Often big brands compose an entire knowledge base with a list of the most asked questions. If the knowledge base does not contain the answer you need, you can always contact the support team, which operates for everyone large companies any direction: sports, fashion, technology, nutrition. Even the operators card games We have our own support service.

There are no fewer questions. On the contrary, every day new questions arise again and again - and all need to be answered. Of course, search engines always come to the rescue in these cases, and I wrote about how to properly search for information on the Internet in an article.

It is quite possible that some of you, dear readers, will information resource will also be of interest. Moreover, this is not a young and newly created project, but a respected site that recently turned 6 years old. Please love and favor: genon.ru.

Note: the genon.ru website is not working.

Guenon is a quick search for answers to questions

Over the years, the resource administration has done everything possible to interest visitors and turn them into their readers. Over the course of a month, this resource is visited by more than 3 million visitors, those who prefer to get answers to their questions here. Dozens of editors and hundreds of partner sites work with Guenon, providing us, visitors with high-quality and reliable information.

For example, to my question “How to cook mushrooms,” I received comprehensive answers on the methods of cooking various mushrooms: champignons, chanterelles, honey mushrooms, boletus and others. There is a feeling that they are doing everything here to ensure that we receive comprehensive answers and are satisfied with the results obtained.

And this, friends, is neither more nor less - a huge time saver. You can even compare by typing exactly the same question into a search engine, and getting hundreds of pages in the search results with supposedly the information I need. I need to go to each site in order to understand where the information is presented to me in a more convenient and understandable form. This will take more than one minute.

But I like to value my time, so I am happy to take note of such information, which ultimately allows me to cope with matters and tasks more effectively.

I ask you not to consider this article as advertising; to be honest, I was surprised when, in response to other similar articles of mine, several times I heard the opinion of readers that the article was custom-made. I only write about what I like and what benefits me and, I hope, my readers.

The authors of the site are happy to write about how the information retrieval system works. Initially, the goal of the site was to ensure that the user received a clear answer to his question. The goal of the project is still relevant today - to improve ways of providing knowledge to people.

For your information, anyone can add their answers by first registering on the site. The information is carefully checked by editors and then entered into the database. Guenon's knowledge base is formed from questions to which there are complete, unambiguous and relevant answers that do not contain any information garbage and advertising of goods and services.

Over the years of work, a system of working with Authors has been formed: there is an incentive scheme that depends on the number of visits to answers and their quality. Become Authors and earn money! This is another source of additional income for you.

Today, for dessert, a video for those who are bored working in the office. I hope you have stickers in stock? All that remains is to learn how to perform various tricks with them!

We offer a selection of interesting questions, the answers to which will make our world clearer and more interesting.

1.Do artificial gravity technologies exist?

Yes. According to the general theory of relativity, the forces of gravity and inertia are fundamentally indistinguishable. The g-force you experience in a car, on an airplane, or on a merry-go-round is the same artificial gravity. Moreover, the carousel, unlike a car and an airplane, can maintain “centrifugal” gravity for an unlimited time. All that remains is to make the space station in the form of a carousel, and it will have artificial gravity.

This is how the pioneers of astronautics imagined cities in orbit. However, such stations are not being built yet, since this involves a lot of technical problems. All other “gravity generators” are science fiction, and not very scientific at that.

2. What will happen to a spider if it gets into the web of another spider?

Most likely, he will be eaten. However, he may survive if he turns out to be much larger than the owner of the web. Then the owner will break the threads holding the unwanted prey so that the alien falls out.

3.How did the witch hunt begin?

On December 5, 1484, Pope Innocent VIII issued a bull against witches, giving broad powers to the Inquisition. Innocent VIII led a far from righteous lifestyle, did not hide his illegitimate children and, apparently, hoped to earn the mercy of heaven in another way - by fighting witchcraft.

Inquisitors Jacob Sprenger and Heinrich Institoris, future authors of the reference book defining witchcraft atrocities and ways to combat them “The Hammer of Witches,” while hunting for the devil’s minions in German cities, encountered opposition from local authorities. Then the zealous Dominicans sent a complaint to the Pope in Rome. He heeded their request and issued a bull that gave the inquisitors unlimited powers and the ability to attract secular authorities of any locality to assist them and called on them to devote all their efforts to eradicating witchcraft.

The bull Summis desiderantes affectibus (“With all the strength of the soul”) designated new stage in the activities of the Inquisition. The resulting terror throughout Europe lasted for several centuries. In the 17th century, the city council of Regensburg seriously feared that, due to the zeal of the Inquisition, there would soon not be a single woman left in the city. Surprisingly, the decree of 1484 has not been formally annulled by the Catholic Church to this day.

4. Is it possible to swing on a swing in zero gravity?

You can’t use regular ones. A swing is a pendulum that swings under the influence of gravity. If this strength is not there, then you cannot swing. However, you can come up with a spring or magnetic swing. You can swing on them in zero gravity if you use body movements with the required frequency shift the center of gravity first to one side or the other.

5.What is a smoking room?

Luchina. The smoking room is a smoldering ray, it gave its name to the children's game. The players passed the board from hand to hand, saying: “Alive, alive, smoking room, thin legs, short soul,” etc. Whoever had the torch in his hands lost, lost. Over time, a smoking room began to be called a person who seemed to have disappeared, but suddenly showed up again.

6.Are there immortal beings?

There are potentially immortals. There are no creatures that cannot be killed. But for some, death is not a natural and necessary end to life. So, life cycle bacteria and many other single-celled organisms are completed by division; as a result, two equivalent organisms are formed, also capable of unlimited reproduction. Plants, including higher ones, also have potential immortality, since they can restore an entire organism from individual parts.

In Sweden, a spruce tree is known that grew back from its roots several times over 9.5 thousand years, and in California an entire oak grove was discovered that was once a single tree that grew back many times after fires over 13 thousand years.

7. Did ancient people have caries?

Yes. An examination of the remains of 52 people who lived 13,700–15,000 years ago on the territory of modern Morocco showed that 49 of them had signs of caries, and many had severely damaged teeth. True, this incidence of the disease was unusually high for that time. Scientists attribute this to the specific nutrition of this tribe, in whose diet a large share was made up of acorns and other seeds. In communities that ate fewer carbohydrate foods, tooth decay was less common.

8. Do animals kiss?

Yes. Animals quite often touch each other with their lips or beaks, expressing affection or affection. However, for a full kiss you need soft and moving lips. Only some mammals have them, including monkeys. Many of their types during family and social contacts They kiss for real, sometimes mutually. In most other mammals, kissing is performed by licking or light biting.

9.Why do surgeons clean their hands with 70% alcohol and not 96%?

This is enough for sterility. Alcohol at a concentration of 70 degrees disinfects almost as effectively as 96 degrees, and it tans the skin less. In addition, 70-proof alcohol is cheaper.

10.Why are there pimples on cucumbers?

These are the remains of thorns. Many species of wild cucumbers are covered with impressive thorns. They prevent animals from eating the fruits before the seeds ripen; then the thorns dry out and break off. However, in the ancestors of the cultivated cucumber, growing in a humid tropical climate, the spines were transformed into organs through which excess water was discharged in droplets. Thus, all that remained of the thorns were tubercles.

11.What exploded in the Big Bang?

False vacuum.Po modern ideas, empty space (vacuum) can be in different energy states. Our familiar space appears to be the lowest energy state of vacuum. However, before the Big Bang, the vacuum could have been in a much more energetic state, called a false vacuum. According to the theory of cosmological inflation, this state is unstable. It was the decay of the false vacuum that could become the source of energy for the Big Bang.

12. How does a baby whale not suffocate if it is born in water?

He is quickly pushed to the surface. Cetaceans do not have hind limbs, and the pelvic bones are reduced and not connected to each other and to the spine, so the birth canal consists almost of soft tissue. Childbirth goes very quickly. The baby whale appears tail first, the head comes out last. Immediately after birth, the mother or other members of the pack push the newborn to the surface of the water so that it can take a breath. Mammals also give birth to sirens in water.

13. Is it true that a person’s nose grows throughout his life?

No. Nose growth usually ends by age 18-20. Subsequently, only its shape changes due to a decrease in the firmness and elasticity of the skin or under the influence, for example, of dehydration of the body. But in some pathological processes in adults, the concentration of hormones that regulate growth increases. In these cases, the nose and ears may actually become enlarged.

14.How far does the laser pointer shine?

Hundreds of thousands of kilometers away. On a wall illuminated by the sun, the spot from the pointer is difficult to see even from 10 meters, and at night it is visible from a hundred meters away. If the beam hits the eye directly, it can blind from 10 km. The maximum distance from which a pointer signal can theoretically be seen in space in the absence of interference is hundreds of thousands of kilometers. At a million kilometers, due to the divergence of the beam, too few photons would reach the eye.

15. How do the police differ from the gendarmerie?

Gendarmes are military men. The phrase gens d’armes is translated from French as “people with weapons.” In France, the gendarmerie is part of the armed forces and reports to the Ministry of Defense. That is, these are military personnel performing police tasks. In addition, gendarmes are entrusted with responsibilities related to the armed defense of the country.

The police are a civilian formation subordinate to the Ministry of Internal Affairs. It ensures public order in the broad sense of the word. IN modern Russia The analogue of the gendarmerie is the internal troops.

16.Where is “in the middle of nowhere”?

No one knows where, but obviously very far away. Once in this phraseological turn the word “Kulizhki” was used, which gradually began to be replaced by “Kulichki”. Back in the 19th century, this replacement was considered erroneous. So, in explanatory dictionary Vladimir Dahl says: “In the middle of nowhere (incorrectly: in the middle of nowhere), I don’t know where.” “Kulizhka” is a diminutive of “kuliga”.

In the eastern dialects of the Russian language, this word meant cleared, uprooted or burned forest for arable land. Kulizhki were, as a rule, located outside the villages, on the outskirts; these were swampy places, and, moreover, according to popular beliefs, inhabited by evil spirits. By the way, Moscow also has its own “kulizhki” (more precisely, Kulishki): this is the name of the area of ​​​​the current Slavyanskaya Square and Solyanka, where there were once fish and salt auctions (hence the name).

When the word “Kulizhka” began to fall out of widespread use, the expression was rethought and turned into “in the middle of nowhere.” However, its meaning has not actually changed: and in fact, where can you find the devil with Easter cakes? According to some linguists, initially the expression “to hell with the middle of nowhere” was an answer to the question: “Where are you going?” Superstitious people avoided answering this question directly, so as not to cause trouble on the road.

17.Who made the parachute?

In 1783, the Frenchman Louis-Sébastien Lenormand made the first successful parachute jump, confirmed by witnesses. Lenormand jumped from the 15-meter tower of the observatory in the city of Montpellier, using a parachute with a wooden frame that he designed.

18.When was the first dollar printed?

The dollar (from the German taler) was declared the monetary unit on July 6, 1785 by the Continental Congress. In the beginning, the dollar was a silver coin. And in 1861, the first banknotes came into circulation, printed on special linen-cotton paper with green ink. One edge of the bills was uneven. The mint kept a spine, the opposite edge of which was exact copy banknote of a certain series. It was used to establish the authenticity of the banknotes.

In August 1862, the Bureau of Engraving and Printing began work. Four women and two men in the basement of the main Treasury building began sorting and stamping $1 and $2 bills that were printed by private companies. Government money printing began in 1863, and by 1877 all US currency had been printed by the Bureau.

Today in the United States there are banknotes in circulation with a date of issue no earlier than 1928 - in denominations of 1, 2, 5, 10, 20, 50, 100, 500, 1000, 5000 and 10,000 dollars. However, banknotes worth more than $100 are prohibited from being exported outside the country. $10,000 bills have not been printed since July 1944, and by the end of the 1980s there were only 348 of these bills in circulation. In 1969, the US Treasury announced the cessation of further issuance of banknotes in denominations above $100. The last $2 bill was printed in 1976.

The front side of the $500 bill features a portrait of McKinley, 25th President of the United States; the $1,000 bill features Stephen Cleveland, 22nd and 24th President; the $5,000 bill features James Madison, 4th President; dollar bill - financier Samon Portland Chace.

The commonly used “buck” comes from buck (English) - deer. It was deer antlers or skins that served as the monetary equivalent in Great Britain. This word took root in the New World, since the British also settled in it.

19.Does a hedgehog change its spines?

Yes, gradually. A hedgehog loses a certain number of quills throughout the year. And when a hedgehog awakens from hibernation, it loses about a third of its needles, in the place of which new ones immediately begin to grow. Therefore, the animal is not defenseless. If a hedgehog's spines fall out faster than they grow back, then most likely he is sick.

20. Why does Chomolungma have a second name - Everest?

Because the first was not known to surveyors. In the 19th century, the British carried out geodetic surveys in the Himalayas. They could not enter the territory of Nepal, which was then closed to foreigners, and took measurements from India at a distance of more than 200 km from the Nepalese peaks.

At that time, Kanchenjunga on the border of Nepal and India was considered the highest mountain. But in 1852, Indian mathematician Radhanath Sikdar, based on measurements made by the British, calculated that the mountain, codenamed Peak XV, should be higher than Kanchenjunga. She needed to be given a name by which the world would recognize her.

Not knowing the Tibetan name of the mountain (Qomolungma), the head of the geodetic survey of British India, Andrew Waugh, named the peak in honor of his predecessor in this post - George Everest.

21.When did light appear?

During the Big Bang, but did not become visible immediately. Visible light is electromagnetic radiation in a certain wavelength range. Radiation existed in the Universe from the very moment of the Big Bang, but in dense hot plasma photons could not move freely: electrons constantly absorbed them and emitted them again, the matter was opaque.

Light began to spread freely through space only 300,000 years later, when the temperature of the universe dropped, electrons merged with nuclei, and the gas became mostly transparent. The light emitted then is now visible as cosmic microwave background radiation.

22.Where did the asteroid fall that supposedly killed the dinosaurs?

Near the Yucatan Peninsula. The crater with a diameter of 180 km was formed by the impact of an asteroid 65 million years ago. According to one hypothesis, the dust and soot it raised reduced the flow of sunlight and warmth. The death of plants led to the extinction of dinosaurs. But many paleontologists point out that the extinction began long before the asteroid hit. And even a serious catastrophe would not have led to the rapid death of the dominant fauna if dinosaurs had not experienced evolutionary competition from mammals.

23. If diamond is the hardest material, then how is it processed?

Diamond. First, jewelers must study the structure of the stone to understand how to process it. Cutting the crystal in the direction of greatest hardness is practically useless. It is sawed in the direction of less hardness, usually using a very thin (hundredths of a millimeter) circular saw, into the blade of which diamond chips are pressed.

So, in essence, the diamond is cutting the diamond, albeit very slowly, over many hours. IN lately Lasers are also used for cutting. Stones are cut and polished using discs containing the same diamond dust. Unfortunately, up to half of the original weight of the diamond is lost during processing.

24.What is Baikal famous for?

Lakes are bodies of water with slow water exchange, occupying about 1.5% of the land surface, which are characterized by the absence of a direct connection with the World Ocean. Hydrogeologists believe that there are about 5 million lakes on Earth, the total water reserve in which is 230 thousand km 3, of which 123 thousand km 3 is fresh.

On a global scale, the supply of drinking water in Lake Baikal, located in Russia, is 1/5 and exceeds the volume of water in the five Great Lakes North America, taken together. In order to imagine how large the water reserve of this lake is, it is enough to say that to fill the lake basin, the deepest point of which lies 5-6 thousand m below ocean level, all the rivers of the world would have to drain water here for 300 days.

Baikal is one of the oldest lakes on the planet. Its age is estimated at 25 million years. Despite such a respectable age, he shows no signs of aging. 336 rivers flow into Baikal, but the main role in the water balance of the lake, namely 50% of the annual influx of water, is played by the waters of the Selenga River. Once in Baikal, its upper 50-meter layer is repeatedly cleaned by the epishura crustaceans (endemics to Lake Baikal) that live in it, is saturated with oxygen and settles for years.

Water exchange in the northern basin of the lake occurs with a periodicity of 225 years, in the middle - 132 years, in the southern - 66 years, which makes it suitable for use as drinking water without any additional purification.

Do you want to ask a question on the Internet, but don’t know how to get it answered? You have to be able to ask questions, it’s not that simple. To do this, you need to try a little, because not everything in life comes easy. Read this article to find out exactly how and where to ask a question in order to get the answer you want.

Steps

Part 1

Look for the answer to your question in a search engine. Before asking your question on a website or forum, look to see if it has already been answered. Try entering your question in the search engine Google system. View the results. Can you formulate search query differently. For example, in the form of a question. Or try searching using keywords.

• Search the Internet for the answer before asking a question, this is very important. If the answer to your question is already online, you may not receive an answer or even be reprimanded when you ask your question.
• If you want to find information on a specific site, add "site:sitename.com" before your query. Google will only show results for this site.

1. Assume this question has been asked before. The Internet is simply huge, so you are unlikely to be the first person in the world to have such a question. Try searching for similar questions and answers online. This will save you a lot of time and effort.

   Check out the FAQ (Questions and Answers) sections. Many sites, services and companies have FAQ (Frequently Asked Questions, translated) sections on their pages and sites. There you can find answers to many questions that concern the clientele and in general world internet community.

   You may be able to find partial answers to the question that interests you. You can use this information you found to better formulate the question that worries you, if you decide to ask it on one of the forums on the Internet. This will show forum users that you are seriously interested in this topic and you are already partly aware of it, or at least We have already looked for answers to our question on the Internet, and all to no avail. This will help them answer your question more accurately.

Part 3

1. The title of the post should be a shortened version of your question. When you create new publication on the forum, pay attention, first of all, to the title. Then describe all known and relevant details within the post to make it easier for forum users to understand and answer your question.

   • For example, “Windows won’t start” is not very good name. Instead, write something more detailed, such as: "Windows 7 won't start and the following error message appears when you turn on your computer:<сообщение>".

2. Then pay attention to the text of the question. After you have chosen the title for your post question, write the body of the question. Here you need to describe in detail the problem you encountered, what you tried to do to fix it, and what happened. Please indicate the sources from which you obtained the information you are using. The more details you provide in the question, the more accurate the answer will be.

   • If you're asking technical question, please indicate detailed information about the program or system you are using. For example, indicate the characteristics of your system, its version, etc., as well as any error messages that you received. If the question is automotive-related, please include the model number and year, as well as the part of the vehicle that is causing the problem.
