30 amazing facts about everything.
Isn’t the world around us amazing? You may have read a lot of interesting things, but there will probably be something else that can 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:
1. Cashews grow on apples? .. In this case, the apple is a false fruit, and the nut grows on top of it.
2. And what about the fact that fungi are closer to animals than to plants in genetic similarity. The common ancestor of fungi and mammals lived (existed) later than the common ancestor of fungi and plants.
3. Well, trees actually grow out of air, not soil. Yes, they get minerals from the soil, 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.
4. 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.
5. There are more stars in the visible universe than grains of sand on all the beaches of the Earth.
6. There are over 125 trillion neural connections in the human brain. The same number of stars will fit into 1,500 galaxies the size of the Milky Way (the Milky Way is a galaxy that includes the solar system).
7. Any atom is 99.99% void, so almost the entire universe is a solid void, including the human body and all objects around us.
8. The human body is constantly replacing its cells. It is completely renewed every ten years. Thus, now you have no more in common with you of 10 years ago than with any other person (in the purely material sense, of course).
9. At the same time, your body has more bacteria than its own cells (by number). But the total mass of bacteria in the human body is only a few kilograms.
10. The legs of a dragonfly are used for landing, but not suitable for walking (moving along the surface).
11. Male clown fish can change sex if there are no females in their population.
12. But with sharks, the opposite is true. If a female shark cannot find a male for a long time, then she is able to fertilize herself. However, sharks still prefer to "use" males for this. In this case, a greater genetic diversity of the species is provided, which contributes to its survival.
13. And some species of sharks are not able to pump air through the gills independently; therefore they are almost always forced to swim so that the water flows itself through the gills in an oncoming stream.
14. Like the annual rings of trees, the concentric rings on the shields of the turtle's shell can be used to determine its age.
15. During the construction of the Egyptian pyramids in the III millennium BC, about 30 million people lived on the entire Earth. Currently, the population of the Earth is increasing annually by about 80 million people.
16. The Egyptian pyramids were as ancient to the inhabitants of Ancient Rome as the Roman Empire itself is to us today.
17. Some of the roads in Italy, built in the days of the Roman Empire, still serve people regularly, requiring absolutely no repair or maintenance.
18. Reading this interesting fact, you finally begin to breathe consciously, and this does not happen very often in life.
19. Most alcoholic beverages contain all 13 minerals essential for humans.
20. At the same time, about 1% of the world's population is currently in a state of strong alcoholic intoxication.
21. On average, an ordinary inhabitant of the Earth covers in his entire life the distance sufficient to circumnavigate the Earth three times.
22. The best-selling product in history at the moment is the Rubik's cube, which, by the way, has 43,252,003,274,489,856,000 possible different configurations.
23. A randomly shuffled deck of ordinary 52 playing cards will contain these cards in an order that has never been stacked anywhere before. The fact is that the number of possible combinations of the arrangement of cards in the deck is equal to the factorial of the number 52, and this is very, very much, approximately 8∙1067. Thus, the probability of repeating one of the combinations of the arrangement of cards, which took place in the past, is negligible (unless you consciously reproduce the repeated combination).
24. Oxygen is necessary for combustion, and hydrogen is a combustible gas, but together they make up water, which does not burn, but besides that can also extinguish fire.
25. Before the eraser was invented, pencil notes and drawings were erased with bread.
26. Peanut butter turns into diamonds under incredible pressure.
27. If you shout at a mug for 10 years, then the received sound energy should be enough to boil the water in it (it's 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 heat up).
28. As strange as it may be, the brain itself invented a name for itself (that is, the word "brain"), and a scientist studying the structure of atoms is nothing more than atoms trying to understand their structure.
29. The sound can be seen. The blast wave generated by a violent explosion can compress the air to such a density that it casts a full shadow.
30. Scientists still haven't 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 reduces its temperature in this way. But no theory has been conclusively proven. However, it is absolutely statistically proven that yawning is contagious. A person is more likely to yawn when they see someone yawning, or when they hear someone else yawn, for example, on the phone.
