8 interesting facts about everything in the world (9 photos)
In order for our brain to constantly develop, we need to learn new information every day. In this post you will read facts that you may learn for the first time.
1. "Tip your tongue"
This expression refers to ornithology. "Pip" is a specific growth that forms on the tongue of some birds. This phenomenon relates to the anatomy of birds, and they wish a person a “pip” when, in the opinion of the interlocutor, he says something not very good.
2. Black box or flight recorder
The name “black box” is essentially untrue, because for visibility purposes, the body of the device is painted bright orange. And the device got its name because of the previously used photographic film, which required complete darkness, so the inside was painted black.
3. Surprise
When we encounter something unexpected, our brain immediately focuses all its attention on the source that surprised us. And in order to absorb as much information as possible, our eyes automatically open wide. Almost the same thing happens with the mouth, because this reflex appeared in our distant ancestors; by opening our mouth slightly, we thereby maximally improve our sense of smell, activating the additional vomeronasal organ.
4. "China's latest warning"
The event, which was called the “Last Chinese Warning,” was associated with the deterioration of relations between the United States and China in the fifties of the last century over the Taiwan issue. The Americans sent reconnaissance planes that violated China's air borders. And for each incident, the United States received a protest warning through diplomatic channels. As a result, the number of violations approached 1000, but no action was taken against the United States.
5. Insects
The most numerous species on the planet are insects. According to scientists, about a million different species of insects live on Earth, which accounts for more than 90% of all species of living beings. Among insects, the largest part are beetles; there are 350 thousand species of them.
6. Anosmia
This is a violation of the sense of smell, which can occur due to a number of reasons - such as head trauma, various infections, allergies and other diseases. Research by scientists has shown that about 5% of the population suffers from anosmia, and this problem can worsen with age.
7. Why you shouldn’t throw batteries in regular trash
There are certain rules for recycling batteries, but not everyone follows them. Each battery, regardless of size (finger or little finger) can lead to contamination of about 20 square meters of land or 400 liters of water with heavy metals such as zinc, manganese, cadmium, nickel, mercury and others. That is, in terms of volume, it is a 25-meter pool of water. In addition, batteries have a decomposition time of about one hundred years.
8. How sleep depends on rain
Surely, many have noticed that before the rain, their eyes close by themselves, and they just want to lie down. Scientists have long studied this phenomenon and came to the conclusion that the fact is that before the rain, atmospheric pressure drops significantly. It is this fact that affects our circulatory system, causing it to lower blood pressure and reduce heart rate. As a result of this, we immediately feel drowsy.
