1. Raindrops are usually depicted in the form of a tear, but this is not the case. They have a spherical shape.
2. During the process of sublimation, a solid substance turns directly into a gas, bypassing the liquid state. For example, this will happen if you throw dry ice into a fire.
3. Gorillas sleep in nests - they make them from soft foliage and curved branches. Males, as a rule, place their nests on the ground, and females - in trees.
4. Champagne fizzes not because of the carbon dioxide in it - it fizzes because of the contact of the gas with dirt and dust. In a completely smooth glass without a single molecule of dust, champagne would not fizz at all.
5. Most of the digestion process occurs not in the stomach, but in the small intestine. This is why a person can suffer from bulimia and remain overweight for some time.
6. The red juice that comes out of the steak is not blood. This is myoglobin - close relative blood. By the time the steak hits the counter, there's barely a drop of blood left in it.
7. For those who want to contribute to conservation environment, it is better to use plastic bags rather than paper bags. Manufacturing process The production and processing of paper bags requires significantly more energy than the production of plastic. And in a landfill, paper bags take up significantly more space.
8. Polar bears' fur is actually transparent and not white as it appears. And the skin is black, not white. And in a warm, humid environment, fur polar bear may turn greenish due to algae.
9. Allergies to pets, as a rule, are not caused by animal hair, as is commonly believed, but by particles of their dead skin or saliva. Regularly washing your pet thoroughly can help relieve allergy symptoms.
10. The map of the tongue, according to which sour, sweet, salty and bitter tastes are perceived by different zones of the tongue, is considered incorrect. This theory was debunked in 1901 by German scientists, who based their proof on the fact that any taste is recognized by any zone of the tongue, based on practical experiments.
11. Many people put a shell to their ear to hear the sea. The sound you hear is actually the sound of your own blood in your veins! You can use any cup-shaped object to hear this effect.
12. While a person is alive, his brain is Pink colour. Only after the brain dies does it turn gray. Therefore, describing the brain as “gray matter” is a little misleading.
13. Mercury is not the only liquid metal. Gallium, Cesium and Francium are metals that are solid at room temperature, but even in the hand they begin to melt at the temperature of the human body.
14. Dolphins do not drink sea water. It can make them sick or even die. They satisfy all their drinking needs by consuming food containing liquid.
Newborns typically have about 270 bones, most of which are very small. This makes the skeleton more flexible and helps the baby pass through the birth canal and grow quickly. As we grow older, many of these bones fuse together. The adult human skeleton consists on average of 200–213 bones.
2. The Eiffel Tower grows 15 centimeters in summer
The huge structure is built with temperature expansion joints, allowing the steel to expand and contract without any damage.
When steel heats up, it begins to expand and takes up more volume. This is called thermal expansion. Conversely, a drop in temperature leads to a decrease in volume. For this reason, large structures, such as bridges, are built with expansion joints that allow them to change in size without damage.
3. 20% of oxygen comes from the Amazon rainforest
Flickr.com/thiagomarraThe Amazon rainforest covers 5.5 million square kilometers. The Amazon jungle produces a significant portion of the oxygen on Earth, absorbing huge amounts of carbon dioxide, which is why it is often called the lungs of the planet.
4. Some metals are so reactive that they explode even when in contact with water.
Some metals and compounds - potassium, sodium, lithium, rubidium and cesium - exhibit increased chemical activity, so they can ignite with lightning speed when in contact with air, and if they are placed in water, they can even explode.
5. A teaspoon of a neutron star would weigh 6 billion tons.
Neutron stars are the remains of massive stars, consisting mainly of a neutron core covered with a relatively thin (about 1 km) crust of matter in the form of heavy atomic nuclei and electrons. The cores of stars that died during a supernova explosion were compressed under the influence of gravity. This is how super-dense neutron stars were formed. Astronomers have found that the mass of neutron stars can be comparable to the mass of the Sun, although their radius does not exceed 10–20 kilometers.
6. Every year, Hawaii gets 7.5 cm closer to Alaska.
The earth's crust consists of several huge parts - tectonic plates. These plates are constantly moving along with the upper layer of the mantle. Hawaii is located in the middle part of the Pacific Plate, which is slowly drifting northwest toward the North American Plate, on which Alaska is located. Tectonic plates move at the same speed as human nails grow.
7. In 2.3 billion years, Earth will be too hot to support life.
Our planet will eventually become an endless desert, similar to today's Mars. Over hundreds of millions of years, the Sun has warmed up, become brighter and hotter, and will continue to do so. In more than two billion years, temperatures will be so high that the oceans that make Earth habitable will evaporate. The entire planet will turn into an endless desert. As scientists predict, in the next few billion years the Sun will turn into a red giant and completely engulf the Earth - the planet will definitely come to an end.

9. Light will take 8 minutes 19 seconds to travel from the Sun to the Earth
It is known that the speed of light is 300,000 kilometers per second. But even at such breakneck speed, it will take time to cover the distance between the Sun and Earth. And 8 minutes is not so much on a cosmic scale. It takes sunlight 5.5 hours to reach Pluto.
10. If you remove all the interatomic space, humanity will fit in a sugar cube
In fact, more than 99.9999% of an atom is empty space. An atom consists of a tiny, dense nucleus surrounded by a cloud of electrons, which occupy proportionately more space. This is because electrons move in waves. They can only exist where the crests and troughs of the waves are formed in a certain way. Electrons do not remain at one point; their location can be anywhere within the orbit. And therefore they take up a lot of space.
11. Stomach juice can dissolve razor blades
The stomach digests food thanks to caustic hydrochloric acid with high content pH (hydrogen index) - from two to three. But at the same time, the acid also affects the gastric mucosa, which, however, can quickly recover. The lining of your stomach is completely renewed every four days.
Scientists have many versions of why this happens. The most likely: due to huge asteroids that influenced its course in the past, or due to strong circulation of air currents in the upper atmosphere.
13. A flea can accelerate faster than the space shuttle
Flea jumps reach mind-boggling heights - 8 centimeters per millisecond. Each jump gives the flea an acceleration 50 times greater than the acceleration of the spacecraft.

Here are a number of interesting and amazing facts about science, which includes research into our Universe, and also touch on the topic of the elixir of immortality and some alarming moments.
What is so interesting about science?
The world of science has inexhaustible information, but where else more information still remains inaccessible to human minds. However, we strive to penetrate the secrets of the universe, which leads us to various discoveries, many of which are extremely fascinating and surprising.
What are some interesting facts about science? various directions Can you give an example today, so that every reader will find something interesting for themselves in each of them? Let's try to talk about the most surprising and relevant ones.
The head of the department of geocryology at one of the Russian universities, Anatoly Brushkov, injected into his body an ancient bacterium that was once discovered in a frozen state in Siberia. As he assures, it contains a gene responsible for longevity. It was found in the region of Yakutia, whose residents have a high life expectancy.
The scientist believes that bacterial cells are endowed with special mechanisms that make it possible to significantly prolong their existence. Brushkov insists that the experiment carried out on himself will be successful, which will someday be confirmed by the extension of his life. Although, how can we know how long he would have lived without this bacterium?
Are we not alone in the Universe?
Interesting facts about science in the field of astronomy often shock the world. Some time ago, during joint research carried out by German and American scientists, it was possible to detect radio signals sent from space. Researchers have no doubt that they come from beyond solar system, and the energy of the source of these signals is conventionally equated to the energy generated by the Sun during the day.
On this basis, a variety of hypotheses are built, and the main one is the opinion that this was an attempt by an extraterrestrial civilization to establish contact with us. Or the signals are a consequence of certain processes occurring in space, about which modern science nothing is known.
Scientists are also confident that the source is located somewhere within our galaxy, and not outside it, and in the near future attempts will be made to determine more accurate coordinates.
Black holes or spatial gates?
Everyone has heard about the existence of black holes in the Universe. These are substances that have great mass and energy, and absorb all matter, including any cosmic bodies. 
Famous physicist Stephen Hawking insists that these holes can act as gates for transition from one Universe to another. However, according to the scientist, a traveler who enters such a gate may find himself in any place in some other Universe, but will never be able to return to this one.
Previously, black holes were considered a dead end, an element of the end of the world. Now Hawking expresses the opinion that this is a one-way tunnel with a one-way ticket. This hypothesis is, in fact, an attempt to answer the question of scientists where bodies and objects can disappear, including sunlight. After all, this contradicts the earthly laws of physics and the main one: energy does not come from nowhere and does not disappear into nowhere.
Endangered bees
Interesting facts about science also emerge in the world of fauna. Scientists suggest that bees may completely disappear from our planet within 20 years. The process of their disappearance is already progressing dynamically. For example, in Russia the number of these insects has almost halved.
Researchers cite the deterioration of the environmental situation as an explanation for this. Besides, rapid development telecommunication systems affects in the form of radio emissions, which also makes it impossible for many species of organisms to exist on Earth.
How much is the Earth worth?
An interesting idea occurred to an American astrophysicist. He considered that the mass of the planets of the solar system and their sizes are no longer interesting to anyone, but the cost is monetary equivalent– new and relevant. In the course of research, GregLaughlin came to the conclusion that our planet is the most expensive of them.
