10 facts that invert our view of the world

The total number of scientists in the world has reached 8 million. If we imagine that each of them has worked in a study for 10 years, it also means that there will be hundreds of discoveries every day. They can span various fields, such as medicine, animal behavior, technology, etc., but there may be some interesting arguments that will make you reverse your view of the world.

Combining this fact, l will break the routine and introduce you to 10 unexpected facts about our world.

1. World City of Crime: Vatican

This paradox has developed due to the method of calculating ratings: In the Vatican, the number of civil and criminal crimes that have occurred in a year has caught up with the number of urban residents, which is indeed a very strange ratio. In the latter city-state, Sao Paulo in Brazil, Lagos in Nigeria and even the Bronx in New York are far from the case.

For example, in 2006, the population of the Vatican was 492, and the number of registered cases in its territory was 827. Therefore, the statistical level of crime is the highest in the world: on average, there are 1.68 incidents per citizen.

2. Sloths can hold their breath for 40 minutes and swim underwater

Such animals are called mammals, and we all know that they are "slow" to measure lifestyle in a gentle way. Of course, they sometimes do not recommend swimming in the water. And they have many surprises: if a sloth can only move 2 meters per minute on land, its speed in the water will increase by 5 times! And because of their slow metabolism, they can last for a while without air.

3. Human tongue does not have a "professional" taste zone

I don’t know if you’ve heard of it: If you like sweetness, just use the tip of your tongue, while the bitterness is closer to the root. But is this true? Of course...wrong! The illusion that different types of taste sensing are distributed throughout the tongue "partitioned" creates a species receptor advantage in a specific location.

4. The sight of dogs is not black and white, they distinguish blue and yellow

Dogs are color blind, which is common sense, but another common sense "dogs see the world in black and white" is wrong. Scientists deny this. Experiments with different colors show that our pets can distinguish blue and yellow. However, the difference between red and green cannot be seen by dogs.

5. After shearing the sheep, the sheep will start fighting because they no longer know each other

In the flock, each sheep has its own rank, and the rank ranking will be determined according to gender and age. The leader of its flock can get the best rest time and can control the behavior of other group members.

But the flock after the "haircut" will re-launch an unusual "revolution". While shearing the wool, it is accompanied by changes in appearance and smell characteristics, as well as loss of status. With the help of the battle, the animals re-recognized the sheep who are now worthy of leading the flock.

6. Newton’s famous apple did not fall on his head

When we were young, we all learned this knowledge in textbooks, Apple; it fell on Isaac Newton, and eventually led to the discovery of the law of universal gravitation, but in fact, the apple did fall, but this happened in Newton. In the eyes. This made the British physicist think about why the trajectory is the same every time.

The biographer of the scientist Williams Teckley mentioned these reflections in his book "The Memory of Newton's Life." Obviously, this text has long been the legend of an apple that the researchers fell on.

7. Changing the wallpaper on the desktop can reduce stress levels

Many people are accustomed to the unruly rules in life. If you feel stressed recently, it is time to make some changes, such as changing the wallpaper on your computer desktop. A new background can relieve stress and increase motivation. In this case, the most effective are natural images, and the worst are urban species and geometric abstraction.

8.Gorillas are worse than bears

 In  addition to our familiar pets, lemurs, guinea pigs, bears, foxes, hyenas, rabbits and squirrels all can hear the purring sounds. The gorilla can start chewing during meal time.

9. In total darkness, human eyes can see burning candles at a distance of 48 kilometers

Do you think you know all your abilities as a human being? But the fact is on the contrary, you may not know how much energy you have. In fact, one can see a further place: if the earth is flat, in a completely dark environment, we can see a small flame burning 48 kilometers away from us, according to the research scientist.

10. A ton of mobile phones contains more gold than a ton of gold ore

According to environmentalists, 1 to 2 grams of gold can be obtained by processing 1 ton of ore.

One ton of the same thing contains about 300 grams of gold. However, the cost of such equipment itself was too high, and such "gold mining" proved to be profitable.

Of course, there are many facts outside the article that can invert our thinking about the world. Share in the comments what you and I don’t know yet.
