Thirty amazing facts about everything

You may have read a lot of interesting things, but there is probably something else to surprise you. This article contains 30 interesting and reliable facts from biology, history, geography, physics and other sciences that will definitely not leave you indifferent.

So, did you know that:

  • Cashew grows on apples? .. In this case, the apple is a false fruit, and the nut grows on its top.
  • But what about the fact that fungi are closer to animals than to plants by genetic similarity. The common ancestor of fungi and mammals lived (existed) later than the common ancestor of fungi and plants.
  • Further, trees actually grow from the air, not from the soil. Yes, they get minerals from the ground, but carbon dioxide comes to them from the air. With the help of the sun, it decomposes into oxygen and carbon, which together with water make up the tree itself.
  • Lake Superior (which is located in North America on the border between the United States and Canada and is the largest and deepest in the Great Lakes system) has so much water that it can cover both Americas with a layer of 30 centimeters.
  • In the visible universe there are more stars than grains of sand on all the beaches of the Earth.
  • In the human brain more than 125 trillion neural connections. The same number of stars will fit in 1,500 galaxies the size of the Milky Way (the Milky Way is a galaxy that includes the solar system).
  • Any atom is 99.99% void, so almost the entire universe is a void, including the human body, and all the objects around us.
  • The human body is constantly replacing its cells. It is fully updated every ten years. Thus, now you have with you, only ten years ago, no more in common than with any other person (in terms of purely material meaning of course).
  • At the same time, there are more bacteria in your body than your own cells (in number). But the total mass of bacteria in the human body is only a few kilograms.
  • The legs of a dragonfly serve for landing (landing), but are not suitable for walking (moving along the surface).
  • Male clown fish can change sex if there are no females in their population.
  • But sharks are the opposite. If a female shark cannot find a male for a long time, then she is able to fertilize herself. However, sharks prefer to “use” males for this. In this case, greater genetic diversity of the species is provided, which contributes to its survival.
  • And also some species of sharks are not able to independently pump air through the gills, so they are forced to almost always swim, so that the water flows through the gills in a free flow.
  • Like the annual rings of trees, the concentric rings on the shields of the tortoise shell can determine its age.
  • During the construction of the Egyptian pyramids in the III millennium BC, about 30 million people lived on the whole Earth. Currently, the world’s population is increasing annually by approximately 80 million people.
  • The Egyptian pyramids were as ancient for the inhabitants of Ancient Rome, as for us today, the Roman Empire itself.
  • Some of the roads in Italy, built during the time of the Roman Empire, still regularly serve people, requiring absolutely no repair and maintenance.
  • Reading this interesting fact, you finally begin to breathe consciously, and this does not happen so often in life.
  • Most alcoholic drinks contain all 13 minerals that are vital for humans.
  • At the same time, about 1% of the world’s population is currently in a state of extreme intoxication.
  • On average, an ordinary inhabitant of the Earth in his entire life travels a distance sufficient to circumnavigate the Earth three times.
  • The best-selling product in history at the moment is the Rubik’s Cube, which, by the way, has 43,252,003,274,489,989,000 possible different configurations.
  • A randomly shuffled deck of regular playing cards, consisting of 52 pieces, will contain these cards in a manner that has never been added before. The fact is that the number of possible combinations of the location of the cards in the deck is equal to the factorial of the number 52, and this is very, very much, about 8 ∙ 1067. Thus, the likelihood of repeating one of the combinations of card arrangement that took place in the past is negligible (unless you repeat the repeating combination consciously).
  • Oxygen is necessary for combustion, and hydrogen is a combustible gas, but together they make up water, which not only does not burn, but also can extinguish a fire.
  • Before the invention, erasers, pencil notes and drawings were washed with bread.
  • Peanut butter turns into diamonds under incredibly high pressure.
  • If you shout at the mug for 10 years, then the received sound energy should be enough to boil the water in it (it’s only a pity that the loss of the same energy during such boiling associated with heat exchange with the environment will not allow the mug even warm up).
  • No matter how strange it may be, the brain itself came up with a name (that is, the word “brain”), and a scientist studying the structure of atoms is nothing more than atoms trying to understand their structure.
  • The sound can be seen. A blast wave formed as a result of a strong explosion can compress the air to such a density that it will cast a full shadow.
  • Scientists still have not figured out what the physiological cause of yawning is. According to one theory, when yawning, a person receives a large portion of oxygen, with its lack in the body. On the other hand, an overheated brain thus reduces its temperature. But not a single theory has been convincingly proven. However, it is absolutely statistically proven that yawning is contagious. A person is more likely to yawn at the sight of a yawn, or when he hears the yawning of the interlocutor, for example, by phone.
