Guys!
This material will introduce you to the rules of safe handling of electricity in a fun way. Remember them, and electricity will become your reliable friend and assistant.
Signor Plugelion
Energyland + gameland.
In the country of Energyland -
A wondrous light shines
In the country of Energyland -
What's missing here!
Electrical devices
There are countless useful ones here.
Lamps, soldering irons,
Ovens, chandeliers, kettles
Visible everywhere here.
And also televisions,
Fireplaces, hair dryers, mixers,
Garlands, refrigerators,
Floor lamps, boilers,
Computers and toasters –
In short, there’s plenty of everything here...
Country Energylandia –
It's so cozy to live in!
But life is even more comfortable
To the one who knows the rules,
And who is ready with the laws
This country should be friends!
Who's talking about these rules?
Doesn't know anything
He will remind him politely
The most famous expert about them -
Signor Plugelion!
Don't go near this wire!
There are a lot of big troubles hidden in it!
I saw the wire - tell those around you,
Tell adults about this as soon as possible!
If next to a broken wire
It turned out to be, remember then:
You have to go to the side with a goose step,
So that no trouble happens to you.
Guys! Don’t any of you know that it’s forbidden to play here in the security zone?!
You are deeply mistaken, girl! This tree will not save you - Lightning is a powerful electric strike, Know: it hits a lonely tree!
Guys, remember: it is dangerous to turn on electrical appliances in the bathroom! Otherwise, not only your health will be affected by the current, but your young life can be lost in an instant!
Remember: forgetting about the iron on, you can suddenly lose your home and everything!
Stop, baby! Stop! Your life is at risk! Apart from the plug, nothing else can be inserted into the socket! Even a five-year-old boy should know this!
Stop! There are wires above the roof! Current always flows through them! And therefore, my friend, learn this law: Neither with hedgehogs nor with friends, do not strive to get there!
Guys! Get away from the tree! Wires in branches are dangerous! And if, on top of that, the weather is damp, then they are twice as scary!
Don’t imitate this Alla, young friend! Otherwise, disaster awaits you - fire!
No! Don't touch this wire! Don’t touch it with your little finger, let alone with your hand! The current does not forgive mistakes and nonsense. A second - and everything will turn into disaster! Sparking wire is deadly - this should never be forgotten! And in order to avoid trouble, you need to immediately call adults for help.
The arrow is drawn here for a reason - After all, my friend, this is a transformer! There is a current of deadly force hidden in it! There is no need to approach him!
Children! Remember the main rule: Whether with a stick, a branch, a pole - never touch the electrical wire - big trouble can happen!
For those who go fishing, guys, you need to remember the most important rule: If you see a power line, if it’s near a river, try to find another place, and lower the fishing rod when you pass where the wires are visible. The fisherman must remember this and know, otherwise he cannot avoid trouble!

Very strict controller
Staring straight from the wall,
He looks and doesn’t blink:
You just have to turn on the light,
Or plug in the oven -
Everything is going wrong.
(Electricity meter)
I run along the paths
I can’t live without a path.
Where am I, guys, no?
The lights in the house won't come on.

It would seem that there are no unresolved questions left for humanity, but despite the latest discoveries in various fields of science, scientists are still trying to find answers to many questions.
Our review contains ten still unsolved mysteries of science.
Secrets of science
1. Why is there more matter than antimatter?
According to modern understanding of particle physics, matter and antimatter are identical but opposite. When they meet, they completely destroy each other and release a large amount of energy. Most of these annihilations must have occurred when the Universe was just beginning. However, there is enough matter left in it to create billions of galaxies, stars, planets and everything else.
Most of the discussion occurs around B mesons, subatomic particles with short half-lives that consist of a quark and an antiquark. The decay of B mesons occurs more slowly than the decay of anti-B mesons, which is why there could be enough B mesons to form everything in the Universe. In addition, B-, D- and K-mesons can vibrate and become antiparticles and back to composite particles. According to one hypothesis, mesons, in all likelihood, take on an ordinary state, which is quite possible, since there are still more ordinary particles than antiparticles.
2. Where did all the lithium go?
At the beginning of the Universe, when temperatures were incredibly high, isotopes of helium, hydrogen and lithium were synthesized in huge quantities. The proportion of hydrogen and helium in the Universe is still very high, but the lithium-7 isotope has been detected only about a third of the level predicted by modeling. There are many different explanations for why this happened, including hypothetical bosons known as axions. They are also thought to have ended up in the cores of stars that our current telescopes and instruments cannot detect. But there is no clear theory why this happened yet.
3. Why do we sleep
Although we know that circadian rhythms (biological clocks) are responsible for wakefulness and sleep, the essence of this phenomenon is not yet known to us. Human sleep consists of several 90-minute cycles of brain activity. Each of these cycles consists of a gradual, slow descent into deeper sleep, and then an abrupt transition into the dreaming phase - the so-called rapid or paradoxical sleep. At the end of REM sleep, the cycle either ends and we wake up, or a new cycle begins. The structure of the human brain is such that in the first half of the night deep slow-wave sleep predominates, and by the morning the rapid phase of sleep intensifies.
Apart from warm-blooded animals (mammals and birds), no living creature has these forms of sleep. In cold-blooded vertebrates and invertebrates, the sleep period is monotonous. However, according to a number of signs, the form of sleep with different phases is very ancient. Most likely, this form of sleep provides some kind of survival advantage because it has been established during evolution. But what this advantage is is still completely unclear.
4. What is gravity
We all know that the gravity of the Moon causes the tides to rise and fall, the gravity of the Earth keeps us on the earth's surface, the gravity of the Sun keeps our planet in orbit, but how well do we understand this? Gravity means that large objects have the ability to attract smaller ones. But why does gravity exist? Why are there so many empty spaces in atoms? Why is the force that holds the constituent parts of an atom together different from gravity? Do gravity particles exist? We cannot answer these questions at the current level of scientific development.
5. Are we alone in the Universe?
The size of the universe we see is 92 billion light years, filled with billions of galaxies with stars and planets. But the only evidence of life is only here on planet Earth. The likelihood that we are the only form of life in the Universe is incredibly low, but why haven’t we contacted anyone yet? This is called the Fermi paradox. Many proposals have been put forward for why this did not happen, and many of them seem quite plausible.
There are many scenarios, maybe we just don’t notice the signals, maybe they have been here for a long time, but we don’t know about it, maybe they don’t want to communicate with us. Or, the most disappointing scenario - Earth is really the only habitable planet in the Universe.
6. What is dark matter made of?
About 80% of the matter in the Universe consists of dark matter. Dark matter is a rather strange thing because it doesn't emit any light. Although its existence was first discussed about 60 years ago, there is still not a single piece of evidence confirming this theory.
The most natural assumption seems to be that dark matter consists of ordinary, baryonic matter, which for some reason weakly interacts electromagnetically and therefore is not detectable when studying, for example, emission and absorption lines. There are other candidates for the role of dark matter composition - these are axions, neutrinos and supersymmetric particles. But a conversation about significant candidates can be conducted on the basis of some facts obtained from observations, but there are no such facts.
How life began
7. Where are we from?
Where did life on Earth come from? How did this happen? Proponents of the “Primal Soup” theory believe that at the dawn of its development, our fertile planet itself formed more and more complex molecules, which subsequently gave rise to life. This could happen in the depths of the ocean, under layers of ice and in the craters of volcanoes. Although DNA is the predominant basis of life on Earth now, it has been suggested that RNA may have dominated early life forms.
In addition, the question arises whether there were other nucleic acids besides RNA or DNA. Did life arise only once, or did it begin once, then be destroyed, and then arise again? Some believe in pansermia, the hypothesis that life was brought to Earth by meteorites or comets in the form of microbes.
8. How plate tectonics occurs
This may seem surprising, but the theory of plate tectonics, moving continents and causing earthquakes, volcanic eruptions and even forming mountains, has become widely known not so long ago. Although the hypothesis that all continents could once have been a single whole was first put forward in 1500, this idea only gained currency in the 1960s, when the theory of ocean floor spreading, based on physical evidence, appeared, according to which blocks of the lithosphere of the oceanic crust move apart and the released space is filled with magma generated in the Earth's mantle. The mystery, however, is what exactly causes these plates to move.
9. How do animal migrations occur?
Many animals and insects migrate throughout the year, trying to avoid seasonal temperature changes and the disappearance of vital food resources, or in search of mates. Some travel thousands of kilometers to do this and then easily find their way back. Different animals use different methods of navigation, including those that take advantage of the Earth's magnetic field and internal compass. However, scientists still cannot understand the entire mechanism of these abilities, how animals know exactly where to go year after year.
The universe is full of mysteries and inexplicable phenomena. Its sheer size is a mystery in itself. And, in the end, no one knows what the Universe is. In this review, we have collected the most incredible mysteries that still haunt scientists today.
1. How old is the universe
At the dawn of the 21st century, despite all the inventions and scientific and technological progress, the age of the Universe remains a mystery. According to the latest expert estimates, the age of the Universe is 13.8 billion years.
2. How galaxies form
There is a lot of discussion about how galaxies formed, but no one really knows for sure. Scientists do not know what happened after the Big Bang: whether small particles began to slowly come together and gradually form stars, star clusters and galaxies, or whether the Universe was originally a structure in the form of clumps of matter, which later split into galaxies.
3. Rectangular Galaxy
It's called the "emerald-shaped galaxy" and was recently discovered by an international team of astronomers from Swinburne University of Technology in Australia. The jewel-shaped galaxy was discovered using the Subaru telescope by Japanese astrophysicist Lee Spitler. The unusual shape is believed to be the result of a collision between two galaxies.
4. The Universe before the Big Bang
Did anything exist before the Big Bang? People will probably never know this.
5. How life appeared on Earth
Scientists know that the Earth was devoid of life when the solar system formed. However, whether the first forms of life arose on Earth or elsewhere is a huge mystery that is the subject of considerable scientific debate. Previously, scientists believed that all life could have arisen spontaneously, but some scientists believe that complex organic molecules may have arisen in space and were brought to Earth by comets or meteorites.
6. Dark matter
No one knows exactly what dark matter is, which is supposedly 22% in the Universe. Because it (presumably) does not emit or interact with electromagnetic radiation, direct observation of dark matter is impossible. The conclusion about its existence was made based on the behavior of astronomical objects and gravitational effects.
7. How big is the Universe
Everyone knows that the Universe is huge. Although the size of the observable universe is about 13.8 billion years, the distance to the edge of the observable universe is about 46 billion light years. This is because the Universe is constantly expanding and has been constantly getting larger the entire time that light has been traveling to Earth.
8. Black holes
The concept of black holes goes back to the 1780s, when John Michell and Laplace proposed the existence of “dark stars” whose gravity was so strong that even light radiation was attracted to them. However, people still don't know much about black holes. For example, in 2014, scientists discovered galaxies with three supermassive black holes in the center (and previously it was assumed that there could only be 1 black hole in the center of the galaxy).
9. Gamma-ray bursts
One of the biggest mysteries in astronomy over the past three decades has been the nature of gamma-ray bursts (the most powerful bursts of energy in the Universe). Scientists can record them and observe them, but they still have no idea why they appear randomly or why they happen in the first place.
10. Dark energy
According to the most generally accepted theory, dark energy should act in opposition to gravity. It makes up approximately 68% of the Universe and causes its expansion. In all other respects, what it is is a complete mystery.
11. Was there a Big Bang?
Our Universe, according to Einstein's theory, is about 13.8 billion years old and was formed from an infinitesimal point during the Big Bang. Although most scientists today accept this model, the scientific community still cannot explain what happened at this small point before the explosion and why it happened.
12. Are people alone in the Universe?
This is another great mystery that many thinkers and scientists have tried to solve throughout the history of human civilization, but have not yet found an answer to it. The question is also whether people will even be able to realize a completely different life - after all, maybe a different type of life is watching people right now, and they don’t even understand it.13. Origin of life
This is without a doubt one of the oldest questions and the biggest mystery in human history. Although there are theories that try to explain this with complex chemical reactions, in reality scientists do not have a clear unambiguous explanation for life.
14. Is everything around true?
Ever since people began to think analytically, this question has been lurking somewhere in the subconscious. And it lies in the following: is what people see what it really is?
15. What gravity really is
Gravity played a large role in the creation of the universe as it exists today. Thanks to the force of gravity, pieces of matter “stick together” into planets, moons and stars. Because of gravity, when a person drops something, the object falls down instead of up. But what this power actually is is unknown. Although scientists can observe and understand how gravity “behaves,” they have no idea why it exists. For example, if gravity is the force that causes all matter to be attracted to all other matter, why is it that atoms are basically empty space inside.
And continuing the unearthly theme - incredible.
